UNDERTAKING DESCRIPTION AND LOCATION District County Route Post Miles Unit E-FIS Project Number Phase District County Federal Project. Number. (Prefix, Agency Code, Project No.) Location 8 Riverside BLRKS 5433 (014) Dune Palms Road, La Quinta, California Project Description: The project proposes to remove the existing low-water crossing of Dune Palms Road at the Coachella Valley Stormwater Channel (CVSC) in the City of La Quinta, Riverside County (see Vicinity and Location Maps in Attachment A). As part of the Dune Palms Road Low Water Crossing Replacement Project, a bridge will be constructed to replace the existing low-water crossing of Dune Palms Road across the CVSC. The existing low-water roadway crossing width is a four lane roadway section with no median, an eight foot wide sidewalk along the western edge, and an eight foot shoulder along the eastern edge of the road which is 68 feet wide. Immediately north of the channel crossing, the existing right-of-way width does accommodate a second northbound through lane. In addition, Dune Palms Road approximately one-quarter mile south of the channel low-water crossing is a four lane roadway with a median. Immediately south of the channel crossing, the existing roadway width is sufficient to accommodate four through lanes. The existing adjacent roadway approach from the south consists of one northbound and two southbound through lanes and the northern roadway approach consists of one through lanes in each direction. The transition from one to two lanes in the southbound direction occurs at the midpoint of the channel crossing. The new three-span bridge will be 480 feet long and 86 feet wide. The bridge typical section consists of a six-foot sidewalk on both sides of the bridge, two (2) eight-foot outside shoulders also serving as bike/golf cart lanes, a 9’8” raised median, two (2) eleven-foot travel lanes, and two (2) twelve-foot travel lanes. The bridge will increase the existing roadway width to accommodate a median area; however, the existing configuration will be modified to accommodate the existing four lane roadway section to the south, and the City’s current improvement project to the north, which will widen Dune Palms Road to four lanes with a continuous center left-turn lane. The proposed improvements will include a significant vertical grade raise to meet the hydraulic requirements of the Coachella Valley Water District (CVWD). The roadway at the bridge approach will be reconstructed to accommodate the raised profile. In order to match the roadway section on the south side of the bridge, the project’s construction limits will be extended to Highway 111. On the north side of the bridge, the project limits will be extended to include a vacant lot north of the project area. The vacant lot is owned by the City and may be used for storage and construction staging. As a part of the bridge construction, concrete slope protection will be installed along the north side of the channel. Additionally, minor removal and replacement of slope protection will be required on the south side of channel west of the proposed bridge and extension of slope protection approximately 300 feet downstream of the proposed bridge. The slope protection will be based on revised CVWD standards for scour countermeasures. As a result of the proposed cast-in-place drilled shaft bridge construction, scour protection within the bottom of the channel is not currently being required by CVWD. The project will also require utility relocations for State of California Transportation Agency Department of Transportation HISTORIC PROPERTY SURVEY REPORT [HPSR form rev 08/07/15] Caltrans, Division of Environmental Analysis.

Page 2 overhead electrical distribution lines (Imperial Irrigation District facility), adjustment to both water valve can and lids and the manhole covers, minor 12” ductile iron pipe water main relocations at each bridge abutment, and relocation of both a 12” and 18” sewer line at the northern bridge abutment. The bridge design will incorporate a special architectural treatment on the bridge railing to achieve the community design goals. Both the north and southbound street approaches will incorporate alternative strategies that will reduce bridge deck noise levels. In addition, the project will follow current Caltrans Design Memo’s for reducing noise generated from traditional concrete bridge decks. The Coachella Valley Association of Governments (CVAG) and the communities within the Coachella Valley are working together on the implementation of a regional Bike/Pedestrian/NEV corridor (CV Link) along Whitewater River and CVSC. In accordance with this plan, the project will be designed to allow for the integration of a trail under crossing within the southern slope protection. It also includes a trail connector to the pedestrian and bike facilities along Dune Palms Road. The project will require right-of- way acquisition on the northeast and southeast corners of the proposed bridge. The existing development at the northeast corner of the proposed bridge consists of a manufactured home park with one single family home on the same parcel of land. However, the existing mobile home park has a number of encroachments with site improvements within the street right of way. The project may require the acquisition and relocation of one single-family residence as a result of the raise in street grade for the proposed bridge. In addition, the project may need to acquire and relocate the residents of one mobile home located to the north of the single family residence. However, the project will be designed to avoid relocation impacts, pending approval by the property owners of a partial property acquisition and access modification. The existing roadway will be modified as a temporary bypass to allow for staged construction of the bridge, and to maintain vehicle and pedestrian access at all times. Temporary and short term access impact may occur during construction, and will require coordination with property owners, the public, and other stakeholders. 2. AREA OF POTENTIAL EFFECTS In accordance with Section 106 Programmatic Agreement Stipulation VIII.A, the Area of Potential Effects (APE) for the Project was established in consultation with Steven Holm, Principal Investigator, Historic Archaeology, and David Lee, District Local Assistance Planner, on November 13, 2017. The APE map is located in Attachment A in this Historic Property Survey Report. The APE was established from the project footprint and includes all direct impacts, temporary construction easements, right-of-way acquisitions, and staging and storage areas. The horizontal limits of the APE north of the CVSC are along the existing street right-of-way, along the west side of Dune Palms Road and include the entire intersection of Westward Ho Drive/Blackhawk Way and Dune Palms Road. The eastern extent of the APE north of the CVSC includes the intersection of Westward Ho Drive/Blackhawk Way and Dune Palms Road and continues east approximately 500 feet to encompass the entireties of city owned parcels 600-030-020, 600-030-004, and 600-030-021, as well as privately owned parcels 600-030-019 State of California Transportation Agency Department of Transportation HISTORIC PROPERTY SURVEY REPORT [HPSR form rev 08/07/15] Caltrans, Division of Environmental Analysis. Copyright © 2014 State of California. All rights reserved. Alteration to the title and section headings is prohibited. Page 3 and 600-030-010. The 35,000 square foot staging area is located within parcels 600-030-021 and 600-030-004. The Dune Palms Mobile Estates mobile home park is located within Parcel 600-030-010. South of the Dune Palms Mobile Estates, the APE includes an approximately 750-foot wide section of the CVSC; this includes approximately 450 feet east of Dune Palms road and an approximately 300 feet west of Dune Palms Road. South of the CVSC, the western limits of the APE include all of parcel 600-390-021, as well as portions of the La Quinta Corporate Center (parcels 600-390-023 and 600-390-010). The eastern extent of the APE south of the CVSC includes the entirety of parcel 600-030-018. The maximum vertical APE is 80 to 100 feet. An Area of Direct Impact (ADI) was defined and includes all areas where ground disturbing activities will take place. The ADI is limited to the area along both sides of Dune Palms Road. However, where the road crosses the CVSC, the ADI extends 300 feet westward into the CVSC and 465 feet eastward into the CVSC. There is a high potential for deeper sediments within the ADI in parcel 600-030-018 to contain archaeological material. Previous testing at P-33-16950 identified subsurface deposits to a depth of 250 centimeters below surface (cmbs). The majority of subsurface artifacts were located within the top 40 cmbs. However, a less dense deeper deposit consisting mainly of charcoal fragments and pieces of fire-affected clay extended to depth of 250 cmbs. Although no subsurface artifacts were identified within the Project ADI during the Extended Phase I program, STPs were terminated at a depth of 80 cmbs and there remains the potential for the ADI to contain unidentified deeper deposits. Sediments in the APE consist of Holocene sand and gravels from the Whitewater River (Qg), Holocene alluvial valley deposits (Qa), and Holocene eolian wind-laid dune sands (Qs). Thus, sediments in the APE are a result of fluvial, alluvial, and eolian deposition, all of which could contain archaeological material. 3. CONSULTING PARTIES / PUBLIC PARTICIPATION X Native American Heritage Commission • A search of the Sacred Lands File was requested from the Native American Heritage Commission (NAHC) on October 22, 2014. On November 6, 2014, the Commission responded stating there that the search failed to indicate the presence of Native American cultural resources within the APE. The NAHC also provided a list of 20 Native American tribes or individuals to be contacted for further information regarding the Project vicinity (HPSR Attachment E). X Native American Tribes, Groups and Individuals • Letters requesting any information related to cultural resources or heritage sites within or adjacent to the Project were sent on 12 November 2014. If no response was received, follow-up emails or phone calls were made on 1 December 2014 and on 9 December 2014. • Agua Caliente Band of Mission Indians –On December 11, 2014, Patricia Garcia on behalf of the Agua Caliente Band of Mission Indians indicated that the project area is not located within the boundaries of Tribe's Reservation. However, it is within the Tribe's Traditional Use area (TUA). Ms. Garcia requested the presence of an approved Native American Cultural Resource Monitor during any ground disturbing activities (including archaeological testing and surveys). If buried cultural deposits are State of California Transportation Agency Department of Transportation HISTORIC PROPERTY SURVEY REPORT [HPSR form rev 08/07/15] Caltrans, Division of Environmental Analysis.

Page 4 encountered, the monitor may request that destructive construction halt and that the monitor shall notify a qualified archaeologist (Secretary of the Interior Standards and Guidelines) to investigate and, if necessary, prepare a mitigation plan for submission to the State Historic Preservation Officer and the Agua Caliente Tribal Historic Preservation office. Ms. Garcia also requested the presence of an archaeologist that meets the Secretary of the Interior standards during any ground disturbing activities and indicated that the Tribe is particularly concerned with site P-33-08692 (CA-RIV- 6190) because it was recorded within the Project Area. A Native American monitor approved by the Agua Caliente Band of Cahuilla Indians monitored the Extended Phase I program and will monitor ground-disturbing activities during construction. • Augustine Band of Cahuilla Mission Indians—On November 25, 2014 Mary Ann Green, Chairperson of the Augustine Band of Cahuilla Mission Indians indicated that she is unaware of specific cultural resources that may be affected by the proposed Dune Palms project. However, she recommended that a Native American monitor be present during all pre-construction and construction phases of the project. She also asked to be notified if any cultural resources are discovered. A Native American monitor approved by the Agua Caliente Band of Cahuilla Indians monitored the Extended Phase I program and will monitor ground-disturbing activities during construction. • Morongo Band of Mission Indians—On December 2, 2014, Denisa Torres, on behalf of the Morongo Band of Mission Indians, indicated that the Dune Palms Project is located outside of the Morongo reservation boundaries but within an area that may be considered a traditional use area or one in which the Tribe has cultural ties (e.g. Cahuilla/Serrano territory). Ms. Torres requested that if human remains are encountered during grading and other construction excavation, work in the immediate vicinity shall cease and the County Coroner shall be contacted pursuant to State Health and Safety Code §7050.5; and, in the event that Native American cultural resources are discovered during project development/construction, all work in the immediate vicinity of the find shall cease and a qualified archaeologist meeting Secretary of Interior standards shall be hired to assess the find. Work on the overall project may continue during this assessment period. If significant Native American cultural resources are discovered, for which a Treatment Plan must be prepared, the developer or his archaeologist shall contact the Morongo Band of Mission Indians. Additionally, if requested by the Tribe, the developer or the project archaeologist shall, in good faith, consult on the discovery and its disposition (e.g. avoidance, preservation, return of artifacts to tribe, etc.). • Los Coyotes Band of Mission Indians, Shane Chapparosa, Chairman—On 12/9/2014, Cogstone was informed that John Perada is responsible for Native American consultation. An email and a voicemail were sent to updated contact information. No response to the inquiry was received from Mr. Perada to date. • Ramona Band of Mission Indians, Joseph Hamilton, Chairman—On 12/9/2014 Cogstone was informed that Mr. John Gomez is responsible for Native American Consultation.

He stated that he received the consultation letter and asked for associated cultural and environmental reports related to the project area. Appropriate documents were sent and no further response was received. The Tribe was contacted subsequently regarding monitoring (see below). • Santa Rosa Band of Mission Indians, John Marcus, Chairman—On December 1st, 2014, the tribal administrator for the Santa Rosa Band of Mission Indians informed Cogstone that the City of La Quinta is in the jurisdiction of the Cabazon Tribes and to please defer to them for consultation. • Cahuilla Band of Indians, Luther Salgado. Mr. Salgado provided updated information and received a digital copy of the consultation letter. No response to date has been received. • Cabazon Band of Mission Indians, Judy Stapp, Director of Cultural Affairs. On November 19th, 2014, Ms. Judy Stapp on behalf of the Cabazon Mission Indians indicated that the Dune Palms Project is located outside of the Tribe's current reservation boundaries. The Tribe has no specific archival information on the site indicating that it may be a sacred/religious site or other site of Native American cultural value. • Ramona Band of Mission Indians, Manuel Hamilton, Vice Chairperson. No response to date has been received. Prior to beginning the Extended Phase I program, another set of letters to Native Americans was sent. A letter providing updated information about the project was sent by the City of La Quinta to the following Native American contacts on April 18, 2017: • Luther Salgado, Chairman, Cahuilla Band of Indians • Ernest Siva, Tribal Elder, Morongo Band of Mission Indians • Karen Kupcha, Augustine Band of Cahuilla Mission Indians • Patricia Garcia-Plotkin, THPO, Agua Caliente Band of Cahuilla Indians • Michael Mirelez, Cultural Resources Coordinator, Torres-Martinez Desert Cahuilla Indians William Vance, Tribal Vice Chairman of the Augustine Band of Cahuilla Mission Indians replied that the Band is unaware of specific cultural resources that may be affected by the proposed project. They recommended that a qualified Native American monitor be present during construction and they wish to be notified if any cultural resources are discovered. A Native American monitor approved by the Agua Caliente Band of Cahuilla Indians monitored the Extended Phase I program and will monitor ground-disturbing activities during construction. The Agua Caliente Band of Mission Indians and the Torres-Martinez Desert Cahuilla Indians were asked if they wished to provide Native American monitors for the project. ECORP contacted Patricia Garcia-Plotkin, the Director of the Tribal Historic Preservation Office for the Agua Caliente Band of Mission Indians and Michael Mirelez, the Cultural Resources Coordinator, for the Torres-Martinez Desert Cahuilla Indians via telephone State of California Transportation Agency Department of Transportation HISTORIC PROPERTY SURVEY REPORT [HPSR form rev 08/07/15] Caltrans, Division of Environmental Analysis.

SUMMARY OF IDENTIFICATION EFFORTS X National Register of Historic Places X California Points of Historical Interest X California Register of Historical Resources _ Caltrans Cultural Resources Database (CCRD) X California Inventory of Historic Resources X Caltrans Historic Highway Bridge Inventory X California Historical Landmarks X California Historical Resources Information System (CHRIS) • Eastern Information Center accessed 10 October 2014. X Other Sources consulted • City of La Quinta Historic Resources Inventory Database (HRID): Negative X Results: • 143 cultural resources investigations have been completed previously within a 1-mile radius of the APE. Of these, 12 studies included portions of the APE. • 120 cultural resources have been identified and documented previously within a 1-mile radius of the APE. Two prehistoric archaeological sites (P-33-08692 and P-33-16950) have been recorded within the APE. Of the other 118 cultural resources within 1-mile of the APE, 11 have been evaluated for inclusion on the NRHP and CRHR; however, none of them are currently listed on either register. Five prehistoric Native American and three historic archaeological sites are located within ¼-mile of the APE. One historic built resource, six historic archaeological sites, and 26 prehistoric Native American archaeological sites are located between ¼-mile and ½-mile from the APE. Finally, two historic built resources, four historic archaeological sites, and 71 prehistoric Native American archaeological sites are located between ½-mile and 1 mile from the APE.

Located adjacent to the APE at the northwestern corner of the Highway 111 and Dune Palms Road intersection, this site was recorded as an extensive prehistoric habitation site with five loci of ceramics, burned bone, debitage, burned clay, and fire affected rock. A jasper Cottonwood Triangular projectile point was also recovered from this site. The Cottonwood Triangular projectile point indicates that this site was a late prehistoric Cahuilla habitation site less than 1000 years old. The site was not evaluated for inclusion in the National Register of Historic Places (NRHP) or the California Register of Historical Resources (CRHR). Aerial photographs and the results of the field survey show that the location of site P-33-08692 in the APE is now occupied by a USA Gasoline station and the La Quinta Corporate Centre. It appears that P-33-08692 no longer exists within the APE. • P-33-16950 (CA-RIV-8835) first was recorded in February of 2008 by CRM Tech. Located in the southeastern part of the APE and entirely within parcel 600-030-018 (see APE Map), the site was initially recorded as a light prehistoric ceramic scatter with daub and fire affected rock. CRM Tech conducted archaeological subsurface testing at the site in April of 2008. Testing revealed the presence of additional ceramic sherds, marine and freshwater shell, groundstone, charcoal, and faunal remains. Cremated human remains were also found during subsurface testing. Seven hundred fourteen artifacts were recovered during surface collection while an additional 712 artifacts were collected during subsurface testing. After human remains were found, additional recovery units were excavated around them revealing the presence of an additional 1,125 artifacts and ecofacts. Based on the results of the test program, CRM Tech did not think that P-33-16950 was a Historical Resource as defined by CEQA. However, when human remains were found, they said that P-33-16950 is a Historical Resource. The site has not been evaluated using NRHP eligibility criteria. As a result of the survey for the current Project (see Attachment B, ASR), ceramic sherds and daub, along with one flake (debitage), were identified near Dune Palms Road in the Area of Direct Impact (ADI) and the P33-16950 site boundary was extended into the ADI. In July 2017 an Extended Phase I subsurface investigation was carried out to determine whether subsurface prehistoric archaeological deposits are present in the ADI. No cultural material associated with site P33-16950 was found in any of the 17 STPs in the ADI. In addition, evidence of previous disturbance was noted in multiple STPs as evidenced by the presence of modern debris at depths exceeding 60 and 70 cm below the surface. Potentially intact native sediments were noted in two STPs at a depth below 60 cm, but no cultural material was noted in these sediments. Based on these results, it appears that the subsurface deposits within P33-16950 do not extend into the ADI and that the surface material in the ADI is part of a modern secondary deposit. Therefore, the site boundary remains as defined in 2008 (see APE Map) . 5.

The improvements would provide safe access across the channel during all weather events, provide reliable routes for emergency vehicles, motorist, pedestrians and bicyclists and achieve the City’s General Plan goals for the corridor. The bridge is funded by the federal Highway Bridge Project program. Caltrans District 8, on behalf of Federal Highway Administration (FWHA), is the federal lead agency for this Project. The Project requires compliance with the January 2014 First Amended Programmatic Agreement Among the Federal Highway Administration, the Advisory Council on Historic Preservation, the California State Historic Preservation Officer, and the California Department of Transportation Regarding Compliance with Section 106 of the National Historic Preservation Act, as it pertains to the Administration of the Federal-Aid Highway Program in California (PA). The cultural resource investigation was conducted within the confines of the approved Area of Potential Effects (APE) for the Project. The cultural resources records search identified two previously documented archaeological sites (P-33-08692/CA-RIV-6190 and P-33-16950/CA-RIV-8835) located within the APE. P-33-08692 (CA-RIV-6190) was recorded as an extensive prehistoric habitation site with five loci of ceramics, burned bone, debitage, burned clay, and fire affected rock in November of 1998 by CRM Tech. P-33-16950 (CA-RIV-8835) was initially recorded as a light prehistoric ceramic scatter with daub and fire affected rock in February of 2008 by CRM Tech. Archaeological subsurface testing and evaluation was conducted by CRM Tech in April 2008 and resulted in the recovery of 712 artifacts consisting of ceramic sherds, marine and freshwater shell, groundstone, charcoal, faunal bone and cremated human remains (Eddy et al. 2008). The testing program identified artifacts at 250 cm in depth but a majority of the artifacts are in the upper 40 cm (1.3 ft) of the site. Based on the testing program CRM Tech concluded that the site as a whole does not appear to qualify as a historical resource. However CRM Tech also stated that since the cremated human remains retain a high degree of Native American traditional cultural value, the portion of the site containing the cremation remains was determined to meet CEQA's definition of a historical resource. The proposed bridge crossing of the Coachella Valley Storm Water Channel (CVC) is located entirely within the APE. Dune Palms Road Low-Water Crossing Replacement Project ASR vii A search of the sacred lands file was requested by Cogstone staff from the Native American Heritage Commission (NAHC) on October 22, 2014. On November 6, 2014, the Commission responded that the search failed to indicate the presence of Native American cultural resources in the immediate vicinity. The NAHC also requested that 20 Native American tribes or individuals be contacted for further information regarding the general Project vicinity. Letters requesting any information related to cultural resources or heritage sites within or adjacent to the Project were sent on 12 November 2014. If no response was received, follow-up emails or phone calls were made on 1 December 2014 and on 9 December 2014. Prior to beginning the Extended Phase I program, another set of letters to Native Americans was sent. A letter providing updated information about the project was sent by the City of La Quinta on April 18, 2017. No responses provided new information on cultural resources. Agua Caliente Band of Cahuilla Indians and Torres-Martinez Desert Cahuilla Indians both requested monitoring for this project; on 20 June, 2017 Torres-Martinez Desert Cahuilla Indians deferred to Agua Caliente Band of Cahuilla Indians for monitoring. Please see HPSR Attachment E for a full description of Native American consultation efforts. On December 29th, 2014, June 23, 2015, July 7, 2015, and August 6, 2016, Cogstone staff conducted a field survey of the APE to verify the location of each previously identified cultural resource, the condition and integrity of the resource, and the identification and recording of new resources. The survey consisted of walking parallel transects, spaced at no greater than 15-meters within the APE while closely inspecting the ground surface. An isolated granitic mano (20141229LAP_1) was found within parcel 600-030-021 of the APE. Site P-33-16950 (CA- RIV-8835) located in APN 600-030-018 was re-identified and an additional light prehistoric ceramic scatter was documented to the northwest of its previously documented boundaries. T his scatter was determined to be an extension of P-33-16950 (CA-RIV-8835) and its boundaries were extended to include the ceramic scatter. This extension places P-33-16950 (CA-RIV-8835) also within APN 600-010-009. Thus the entirety of the site is within the proposed APE and the possibility of intact subsurface features varies across the site. The geoarchaeological analysis indicates the potential for buried archaeological deposits ranges from low to medium potential in the APE. Areas of low potential are located within the Coachella River bed. The rest of the APE is assigned a medium potential for buried archaeological deposits. Additional research was conducted in order to understand to what extent previous disturbances within APN 600-030-018 may have affected the distribution of cultural materials from P-33-16950 (CA-RIV-8835). Cogstone reviewed the Coachella Valley Stormwater Channel Plan and Profile, the Off-site Improvement Plan for the La Quinta Corporate Centre, aerial photography, and additional information regarding the extent of construction disturbances as a result of the channelization of the Whitewater River and the installation of sewer pipes provided by the City’s design consultant. Research shows that the northern portion of P-33-16950 (CA- RIV-8835) that is within the APE has been disturbed by previous construction activities. New Dune Palms Road Low-Water Crossing Replacement Project ASR viii and updated DPR forms were drafted for P-33-08692 (CA-R IV-6190) and P-33-16950 (CA- RIV-8835) (Appendix E). It is Caltrans' policy to avoid cultural resources whenever possible. Further investigations may be needed if the site[s] cannot be avoided by the Project. If buried cultural materials are encountered during construction, it is Caltrans' policy that work stop in that area until a qualified archaeologist can evaluate the nature and significance of the find. Additional survey will be required if the Project changes to include areas not previously surveyed. Dune Palms Road Low-Water Crossing Replacement Project ASR 1 INTRODUCTION The purpose of this study is to identify cultural resources which may be affected by construction- related activities for Dune Palms Road Low-Water Crossing Replacement Project [Federal Project No. BLRKS – 5433(014)] in western Riverside County, California (Figure 1). Specifically, the proposed Project involves the replacement of the existing low-water crossing spanning the Coachella Valley Storm Water Channel (CVSC) at Dune Palms Road with an all- weather access bridge, located immediately north of Highway 111 and south of Westward Ho Drive in the City of La Quinta, California. Cogstone Staff Archaeologists Lindsay Porras, Desiree Martinez, and Lynn Furnis surveyed the Project Area on December 29, 2014, June 23, 2015, and August 6, 2016 respectively. Qualifications can be found in the Project Personnel section and Appendix A. Figure 1. Project Vicinity Map Dune Palms Road Low-Water Crossing Replacement Project ASR 2 PROJECT LOCATION AND DESCRIPTION PROJECT LOCATION The purpose of the Project is to replace the existing low-water crossing spanning the Coachella Valley Storm Water Channel (CVSC) at Dune Palms Road with an all-weather access bridge. The proposed improvements will accomplish the following in the Project area: • Provide safe access across the CVSC (Whitewater River) during all-weather events • Provide reliable route for emergency vehicles, motorists, pedestrians, and bicyclists • Achieve the City’s General Plan goals for the corridor The Project is located immediately north of Highway 111 and south of Westward Ho Drive in the City of La Quinta, western Riverside County, California (Figure 2). Located entirely within the City limits of La Quinta, the Project is depicted on the La Quinta 7.5 minute USGS quadrangle in Sections 20 and 29; Township 5 South, Range 7 East, San Bernardino Baseline and Meridian (Figure 2). PROJECT DESCRIPTION The Project proposes to remove the existing low-water crossing of Dune Palms Road at the CVSC in the City of La Quinta, Riverside County. The crossing will be replaced with a 480 feet long and 86 feet wide four-span bridge. The bridge typical section consists of six-foot sidewalk on both sides of the bridge, two (2) eight-foot outside shoulders also serving as bike/golf cart lanes, a 10 foot raised median, two (2) eleven-foot travel lanes, and two (2) twelve-foot travel lanes (Figure Appendix C-1). The proposed configuration will be consistent with the existing four lane roadway section to the south, and the City’s current improvement project to the north (project number 2009-04), which will widen Dune Palms Road from two to four lanes with a median and left turn lanes. The proposed improvements will include a reconstruction of the north and south bridge approaches to accommodate the significant raised profile of the roadway. In order to match the roadway section on the south side of the bridge, the Project’s construction limits will be extended to 239 feet north of Highway 111. On the north side of the bridge, the construction limits are extended along Dune Palms Road to the north and includes a portion of the vacant lots, Accessor’s Parcel Numbers (APNs) 600-030-004 & 600-030-021), located approximately 850 Dune Palms Road Low-Water Crossing Replacement Project ASR 3 feet north of the storm water channel. The vacant lots are owned by the City and will be offered by the City in the bidding documents to be used for storage and construction staging by the contractor for the construction of this Project. As a part of the bridge construction, concrete slope protection will be installed along the north side of the channel. Additionally, minor removal and replacement of slope protection will be required on the south side of the channel west of the proposed bridge and extension of slope protection approximately 465 feet east (downstream) of the proposed bridge. The slope protection is needed for scour countermeasures. As a result of the proposed cast-in-place drilled shaft bridge construction, scour protection within the bottom of the channel should not be required. The installation of the concrete slope protection will require the existing channel bank to be excavated at a 1.5:1 (horizontal to vertical) slope to the bottom of the channel, then at a 1:1 slope to the bottom of the slope protection. The current dirt channel bank is at an approximate slope of 2:1 to 2.5:1. A portion of archaeological site P-33-16950 is located within the proposed construction activities for the slope protection. Extended Phase I (XPI) testing is proposed to determine the subsurface extent of the site which is currently unknown at this location. As a result of the existing low water crossing acting as a quasi-grade control structure for the CVSC, sediment has been deposited on the upstream side of the channel from Dune Palms Road since the original construction. Additionally, on the downstream side of the Dune Palms Road crossing, the channel has an area of scour. Therefore the elevation differential between the upstream and downstream channel bottom approximately eleven (11) feet. The Project will grade the bottom of the channel 300 feet west and east, up and downstream, respectively, of the crossing to provide a uniform channel bottom slope within the Project Area. The Project will also include the following additional improvements: • Railing Architectural Treatment. The bridge design will incorporate railing architectural treatment as required by the City’s standard design. • Integration of a Regional Bike/Pedestrian/ Neighborhood Electric Vehicles (NEV) Corridor (CV Link). The Coachella Valley Association of Governments (CVAG) and the communities within the Coachella Valley are working together on the implementation of a regional CV Link along Whitewater River and Coachella Valley Storm Water Channel. The Project design will be consistent with these plans by allowing for the integration of a trail under crossing within the southern slope protection, which also includes a trail connector to the pedestrian and bike facilities proposed along Dune Palms Road in the Project Area. • Utility Relocation. The Project will require utility relocations for the Imperial Irrigation District (IID) overhead electrical distribution lines, adjustment to the both water valve can and lids and the manhole covers, minor 12 inch ductile iron pipe Dune Palms Road Low-Water Crossing Replacement Project ASR 4 water main relocations at each bridge abutment, and relocation of both a 12 inch and 18 inch sewer line, under the operations of Coachella Valley Water District (CVWD), at the northern bridge abutment. Both the water main and sewer line relocations would be minor in nature, with the relocation limited to the existing road right and/or channel of way. The relocation of the overhead electrical lines is considered by IID as a minor relocation, due to a parallel underground system along the west side of Dune Palms Road. The Project will coordinate with IID on providing the missing underground link crossing the channel through the placement of conduit on the proposed bridge. The placement of the electrical system on the bridge will mostly likely allow IID to eliminate the overhead distribution facility along the east side of the road. For the water main, the relocation is also considered minor by CVWD standards. The two possible solutions for relocation would be either minor realignment work at the two abutments to eliminate any possible conflicts with abutment construction or relocation of the full length crossing the channel onto the bridge. All utility relocation will be within the current APE. The Project will require right-of-way acquisition from three parcels within the APE, located in the northeast, southwest and southeast corners of the proposed bridge or APNs 600-030-010, 600-390-021 and 600-030-018 respectively. APNs 600-030-010 and 600-030-018 will require both street right of way acquisition as well as a temporary construction easement, and APN 600- 390-021 will require only a temporary construction easement. Note, the Project will not require any additional street right of way nor construction easements from the High School property (APN 600-010-004) located at the northwest corner of the Project. The existing development at the northeast corner of the proposed bridge consists of a Mobile Home Park with one single family home (APN 600-030-010). Some of the mobile homes adjacent to the Dune Palms Road are encroaching within the street right of way. The Project may require the acquisition of the single-family home site and relocation of two mobile homes residents. The Project will be designed to avoid and minimize relocation impacts of the mobile homes. The existing roadway will be modified to construct a temporary bypass road. The temporary bypass will allow for staged construction of the bridge, and maintain vehicle and pedestrian access at all times. Temporary and short term access impact may occur during construction, and will require coordination with property owners, the public, and other stakeholders. Dune Palms Road Low-Water Crossing Replacement Project ASR 5 Figure 2. Project Location Map Dune Palms Road Low-Water Crossing Replacement Project ASR 6 The proposed construction of the all-weather bridge at this location will require the raising of Dune Palms Road on both the northern and southern roadway approaches to accommodate the required flood flows conditions for the CVSC. The centerline of the road will be raised approximately 9.5 feet at the northern approach and approximately 12.9 feet at the southern approach. Minor grading will be required to prepare the existing ground to accept the fill material necessary to accommodate the proposed profile grade. At the south roadway approach along the east side of Dune Palms Road, the proposed fill will create a slope that will generally extend between 32 to 50 feet from the existing eastern edge of Dune Palms Road to the new toe of slope. At this location, the Project will most likely require a temporary construction easement outside of the noted toe of slope to allow for the construction of the slope. The current temporary construction easement is anticipated to be 55 feet from the existing street right of way. Within the area under the proposed fill slope embankment between the existing edge of pavement and the toe of slope, the existing ground will need to be over excavated up to 12 inches and re- compacted prior to initiating any placement of embankment fill (Figures Appendix C-1 to C-3). Along the west side of the roadway approach south of the channel, the abutting land has been fully developed making it likely that a retaining wall will be constructed along the right of way line to accommodate the proposed change in roadway grade. Along this frontage, the existing ground will need to be excavated up to 3 feet to allow for the placement of the wall footing. Note, the current ground is approximately 2 to 3 feet lower than the existing ground in the undeveloped condition. Therefore, the prior noted excavation depth for the proposed retaining wall will be 5 to 6 feet below the undeveloped ground elevation. AREA OF POTENTIAL EFFECTS The Area of Potential Effects (APE) includes both horizontal and vertical limits (Figure 3). The APE totals 48.5 acres. The horizontal limits of the APE north of the CVSC are along the existing street right-of-way, along the west side of Dune Palms Road and include the entire intersection of Westward Ho Drive/Blackhawk Way and Dune Palms Road. The eastern extent of the APE north of the CVSC includes the intersection of Westward Ho Drive/Blackhawk Way and Dune Palms Road and continues east approximately 500 feet to encompass the entireties of city-owned APNs 600-030-020, 600-030-004 and 600-030-021 as well as privately owned APNs 600-030- 019 and 600-030-010. The 35,000 square foot staging area is located within APNs 600-030-021 and 600-030-004. The Dune Palms Mobile Estates mobile home park is located within APN 600- 030-010. South of the Dune Palms Mobile Estates, the APE includes an approximately 750 foot wide section of the CVSC; this includes approximately 450 feet east of Dune Palms Road and approximately 300 feet west of Dune Palms Road. South of the CVSC, the western limit includes all of APN 600-390-021 as well as portions of the La Quinta Corporate Center (APNs 600-390- 023 and 600-390-010). The eastern extent of the APE south of the CVSC includes the entirety of Dune Palms Road Low-Water Crossing Replacement Project ASR 7 APNs 600-030-018. South of the storm water channel, work outside of the existing street right of way will occur on both sides of Dune Palms Road. North of the channel, work outside of the existing street right of way will occur along the east side of Dune Palms Road. The utility relocation is not included in the vertical APE because it does not require any ground disturbing work. The overhead electrical line along the east side of Dune Palms, south of the channel will be abandoned and relocated to the west side through an existing underground conduit system. A large majority of the Project, excluding the bridge section, is within a fill condition where the placement of fill on top of the over excavated existing ground will occur; therefore, the following indicates the anticipated excavation depths per specific Project areas. The typical maximum vertical excavation of the APE outside of the stormwater channel area would be 1 foot in undisturbed areas outside of the existing street right of way section (west of Dune Palms and south of the stormwater channel). During ground disturbing activities in these undisturbed areas it is possible that construction may unintentionally extend to a depth great then 1 foot. As a precaution, a buffer has been added to the vertical APE to encompass any such incidents. The maximum vertical depth of the APE for this portion of the Project is 2 feet. The maximum vertical depth of the APE within the existing roadway street right of way section and within previously disturbed areas (mobile home park) is a maximum of 4 feet. The maximum vertical depth of the APE for the portion of the Project within the channel area is up to 80 feet of excavation for the bridge piers and up to 40 feet of excavation along the channel banks for the installation of the concrete slope protection. The construction of bridge piers would be accomplished by a large diameter (8 foot) auger. Construction activities parallel to the Stormwater channel will not extend any further south than the previously installed sewer main. Therefore, the location of the sewer main would be the southernmost boundary of any proposed construction activities on this Project (Appendix C-2). Table 1 is a summary of the anticipated depths of proposed fill and excavation per work location. Figure Appendix C-3 shows a profile view of the depths for the sewer main excavations parallel to Dune Palms Road and the stormwater channel.

Project Map with APE boundaries Dune Palms Road Low-Water Crossing Replacement Project ASR 11 SOURCES CONSULTED CALIFORNIA HISTORICAL RESOURCES INFORMATION SYSTEM On October 29, 2014, Cogstone staff archaeologist Lindsay Porras conducted a search for archaeological and historical records at the Eastern Information Center (EIC) of the California Historical Resources Information System (CHRIS). The record search covered a one-mile radius around the APE boundaries. The records search indicated that 143 cultural resources investigations have been completed previously within a 1-mile radius of the APE (Appendix B). Of these, 12 studies included portions of the APE (Figure 4). The results of these studies indicate that 120 cultural resources have been identified and documented previously within a 1-mile radius of the APE (Table 2). There are two known archaeological site within the APE (P-33-08692 /CA-RIV -6190 and P-33-16950/CA-RIV -8835) (Figure Appendix C-4). P-33-08692 (CA-RIV-6190) is located at the northwestern corner of the Highway 111 and Dune Palms Road intersection and within the southwest portion of the APE mapped within APNs 600- 390-010, 600-390-007, and 600-390-023. It was recorded as an extensive prehistoric habitation site with five loci of ceramics, burned faunal bone, debitage, burned clay, and fire affected rock in November 1998 by CRM Tech. No human remains were positively identified at the site; however, 23 fragments were identified as possibly human due to their consistency with human cremations in the region. A jasper Cottonwood Triangular projectile point and Salton Buffware ceramic sherds were also recovered from this site. The Cottonwood Triangular projectile point and sherds indicate that this site was a late prehistoric Cahuilla habitation site less than 1000 years old (Love et al. 1998). CRM Tech performed testing at the site in conjunction with monitoring during construction of the Hotel 111 and La Quinta Corporate Centre. The site was not evaluated for inclusion on the National Register of Historic Places (NRHP) or the California Register of Historical Resources (CRHR) at the time of testing. Based on the testing and monitoring results, Love (2000) stated that the research potential of the site was exhausted and recommended that the site not be considered a historical resource. It is assumed that the site has been destroyed been destroyed b y the grading and construction activities of Hotel 111 and the La Quinta Corporate Centre and the USA Gasoline station. P-33-16950 (CA-RIV-8835) is located in the southeastern portion of the APE and was mapped entirely within parcel 600-030-018. The site was initially recorded as a light prehistoric ceramic scatter with daub and fire affected rock in February 2008 by CRM Tech. CRM Tech conducted archaeological subsurface testing and evaluation of the site in April of 2008 (Eddy et al. 2008). Testing included the hand excavation of 8 test units (TUs) measuring 1 meter (m) by 1 m or 1 m Dune Palms Road Low-Water Crossing Replacement Project ASR 12 by 2 m, twenty-three 50 centimeter (cm) by 50 cm shovel test pits (STPs), as well as two backhoe excavated trenches measuring 10 m by 2 m and three 2 m by 1 m backhoe excavated pits (Figure Appendix C-5). The TUs were excavated to 100 cm below ground surface (cmbs), STP depth ranged from 50 cmbs to 100 cmbs, while the backhoe trenches and pits were excavated to 150 cmbs to 250 cmbs. Seven hundred and fourteen artifacts (e.g. prehistoric ceramic sherds, daub/fire affected clay (FAC), groundstone fragments, and rocks) were recovered during surface collection prior to testing. Seven hundred and twelve artifacts consisting of ceramic sherds, marine and freshwater shell, groundstone, charcoal, faunal bone and human remains were recovered from the TUs. Additionally, twenty-seven 1m by 1 m recovery units (RUs) were hand excavated around the location of the human remains resulting an additional 1,125 artifacts and ecofacts. The depth of the RUs ranged from 20 cmbs to 40 cmbs. The report did not report which artifacts were identified at what depth. Based on the testing program CRM Tech concluded that the site in general had “very limited ability to provide important new information for the study of prehistory in the Whitewater River Delta/ Dune Complex and surrounding region, [and] in light of the low quantity of formal artifacts it yielded… the site as a whole does not appear to qualify as a ‘historical resource’." However CRM Tech also stated that since the cremated human remains retain a high degree of Native American traditional cultural value, the portion of the site containing the cremation remains was determined to meet CEQA's definition of a historical resource. Although the testing program at P-33-16950 (CA-RIV-8835) identified artifacts at 250 cm in depth, the type and quantity of artifacts were not listed in the report. Cogstone obtained a copy of the original catalog from Michael Hogan of CRM Tech. The catalog shows that a majority of the artifacts are in the upper 40 cm (1.3 ft) of the site (Table Appendix C-1). Sixteen items were found between 100 cm and 250 cm in depth. These items included 6 pieces of FAC, 1 piece of unburned sandy clay, 5+ pieces of unburned clay, 1 faunal bone fragment, and 3 pieces of charcoal. Of the other 118 cultural resources within 1-mile of the APE, 11 have been evaluated for inclusion on the NRHP and CRHR; however, none of them are currently listed on either register. Five prehistoric and three historic archaeological sites are located within ¼-mile of the APE. One historic built resource, six historic archaeological sites, and 26 prehistoric archaeological sites are located between ¼-mile and ½-mile from the APE. Finally, two historic built resources, four historic archaeological sites, and 71 prehistoric archaeological sites are located between ½-mile and 1 mile from the APE (Table 2). Within the 1 mile record search radius, a total of ten archaeological sites include cremated human remains. These include P-33-150 (CA-RIV-150), P- 33-1177 (CA-RIV-1177), P-33-1178 (CA-RIV-1178), P-33-3659 (CA-RIV-3659), P-33-4754 Dune Palms Road Low-Water Crossing Replacement Project ASR 13 Figure 4.

Agua Caliente Band of Mission Indians –On December 11, 2014, Patricia Garcia on behalf of the Agua Caliente Band of Mission Indians indicated that the project area is not located within the boundaries of Tribe's Reservation. However, it is within the Tribe's Traditional Use area (TUA). Ms. Garcia requested the presence of an approved Native American Cultural Resource Monitor during any ground disturbing activities (including archaeological testing and surveys). If buried cultural deposits are encountered, the monitor may request that destructive construction halt and that the monitor shall notify a qualified archaeologist (Secretary of the Interior Standards and Guidelines) to investigate and, if necessary, prepare a mitigation plan for submission to the State Historic Preservation Officer and the Agua Caliente Tribal Historic Preservation office. Ms. Garcia also requested the presence of an archaeologist that meets the Secretary of the Interior Dune Palms Road Low-Water Crossing Replacement Project ASR 26 standards during any ground disturbing activities and indicated that the Tribe is particularly concerned with site P-33-08692 (CA-RIV-6190) because it was recorded within the Project Area. A Native American monitor approved by the Agua Caliente Band of Cahuilla Indians monitored the Extended Phase I program and will monitor ground-disturbing activities during construction. Augustine Band of Cahuilla Mission Indians—On November 25, 2014 Mary Ann Green, Chairperson of the Augustine Band of Cahuilla Mission Indians indicated that she is unaware of specific cultural resources that may be affected by the proposed Dune Palms project. However, she recommended that a Native American monitor be present during all pre-construction and construction phases of the project. She also asked to be notified if any cultural resources are discovered. A Native American monitor approved by the Agua Caliente Band of Cahuilla Indians monitored the Extended Phase I program and will monitor ground-disturbing activities during construction. Morongo Band of Mission Indians—On December 2, 2014, Denisa Torres, on behalf of the Morongo Band of Mission Indians, indicated that the Dune Palms Project is located outside of the Morongo reservation boundaries but within an area that may be considered a traditional use area or one in which the Tribe has cultural ties (e.g. Cahuilla/Serrano territory). Ms. Torres requested that if human remains are encountered during grading and other construction excavation, work in the immediate vicinity shall cease and the County Coroner shall be contacted pursuant to State Health and Safety Code §7050.5; and, in the event that Native American cultural resources are discovered during project development/construction, all work in the immediate vicinity of the find shall cease and a qualified archaeologist meeting Secretary of Interior standards shall be hired to assess the find. Work on the overall project may continue during this assessment period. If significant Native American cultural resources are discovered, for which a Treatment Plan must be prepared, the developer or his archaeologist shall contact the Morongo Band of Mission Indians. Additionally, if requested by the Tribe, the developer or the project archaeologist shall, in good faith, consult on the discovery and its disposition (e.g. avoidance, preservation, return of artifacts to tribe, etc.). Los Coyotes Band of Mission Indians, Shane Chapparosa, Chairman—On 12/9/2014, Cogstone was informed that John Perada is responsible for Native American consultation.

Cahuilla Band of Indians, Luther Salgado. Mr. Salgado provided updated information and received a digital copy of the consultation letter. No response to date has been received. Cabazon Band of Mission Indians, Judy Stapp, Director of Cultural Affairs. On November 19th, 2014, Ms. Judy Stapp on behalf of the Cabazon Mission Indians indicated that the Dune Palms Project is located outside of the Tribe's current reservation boundaries. The Tribe has no specific archival information on the site indicating that it may be a sacred/religious site or other site of Native American cultural value. Ramona Band of Mission Indians, Manuel Hamilton, Vice Chairperson. No response to date has been received. Prior to beginning the Extended Phase I program, another set of letters to Native Americans was sent. A letter providing updated information about the project was sent by the City of La Quinta to the following Native American contacts on April 18, 2017: Luther Salgado, Chairman, Cahuilla Band of Indians Ernest Siva, Tribal Elder, Morongo Band of Mission Indians Karen Kupcha, Augustine Band of Cahuilla Mission Indians Patricia Garcia-Plotkin, THPO, Agua Caliente Band of Cahuilla Indians Michael Mirelez, Cultural Resources Coordinator, Torres-Martinez Desert Cahuilla Indians William Vance, Tribal Vice Chairman of the Augustine Band of Cahuilla Mission Indians replied that the Band is unaware of specific cultural resources that may be affected by the proposed project. They recommended that a qualified Native American monitor be present during construction and they wish to be notified if any cultural resources are discovered. A Native American monitor approved by the Agua Caliente Band of Cahuilla Indians monitored the Extended Phase I program and will monitor ground-disturbing activities during construction. Dune Palms Road Low-Water Crossing Replacement Project ASR 28 The Agua Caliente Band of Mission Indians and the Torres-Martinez Desert Cahuilla Indians were asked if they wished to provide Native American monitors for the project. ECORP contacted Patricia Garcia-Plotkin, the Director of the Tribal Historic Preservation Office for the Agua Caliente Band of Mission Indians and Michael Mirelez, the Cultural Resources Coordinator, for the Torres-Martinez Desert Cahuilla Indians via telephone calls on May 31, 2017. Both Tribes initially expressed interest in providing monitors for the Project. Agua Caliente agreed to supply a Native American monitor on June 25, 2017. Mr. Mirelez of Torres- Martinez stated that the Tribe could not find a qualified monitor. Mr. Mirelez deferred to the Agua Caliente for Native American monitoring for the study. Native American monitors were supplied by the Agua Caliente Band for the entirety of the Extended Phase I fieldwork. Native American monitors were supplied by the Agua Caliente Band for the entirety of the Extended Phase I fieldwork and Native American monitors approved by the Agua Caliente Band of Cahuilla Indians will monitor ground-disturbing activities during construction. No responses have been received to date from Luther Salgado, Chairman, Cahuilla Band of Indians and Ernest Siva, Tribal Elder, Morongo Band of Mission Indians. Documentation of Native American consultation is in HPSR Attachment E. BACKGROUND The environmental setting section, below, provides information on the environmental factors that affect cultural resources, while the prehistoric and historical settings provide information on the land use history of the general Project region. ENVIRONMENT Located in the Coachella Valley, La Quinta enjoys a subtropical desert climate. The San Jacinto and Santa Rosa Mountains flank the City on the west with the San Bernardino and Little San Bernardino Mountains bordering it on the north and east, respectively. Mean annual rainfall is very low from the desert floor into the foothills, ranging from 3 to 6 inches per year and averaging about 5 to 6 inches along the Little San Bernardino foothills (Coachella Valley Water District n.d.). Most of the rainfall occurs during the cooler months of November through March, but occasional high-intensity thunderstorms and tropical monsoonal storms occur in late summer and early fall. Although the ground may be generally dry at the beginning of a storm, sufficient amounts and intensities of rainfall can saturate the surface, substantially reducing percolation and increasing runoff. Development also increases runoff by creating large areas of impermeable surfaces. Increased runoff upstream can contribute significantly to downstream flooding damage. Dune Palms Road Low-Water Crossing Replacement Project ASR 29 Summer daytime temperatures can occasionally exceed 125°F and winter temperatures rarely fall below freezing. The surrounding mountain slopes generally receive rainfall that increases with elevation. The mountains and upper elevations surrounding the Project study area are generally cooler, with an approximate 5°F drop with every 1,000-foot increase in elevation. Potential flooding problems in the La Quinta study area are associated with storm flows in the Whitewater River and its tributaries, flooding on the alluvial fans, and to runoff associated with the Indio Hills and the San Bernardino and Little San Bernardino mountain foothills. PREHISTORIC CULTURAL SETTING Approaches to prehistoric frameworks have changed over the years from those being based on material cultural attributes to radiocarbon-based chronologies to those associated with cultural traditions. Archaeologists defined a material complex consisting of an abundance of milling stones (for grinding food items) with few projectile points or vertebrate faunal remains dating from about seven to three thousand years before the present as the “Millingstone Horizon” (Wallace 1955). Later, the “Millingstone Horizon” was redefined as a cultural tradition named the Encinitas Tradition (Warren 1968) with various regional expressions including Topanga and La Jolla. Use by archaeologists varied as some adopted a generalized Encinitas Tradition without regional variations, some continued to use “Millingstone Horizon,” and some used Middle Holocene (the geologic time period) to indicate this observed pattern (Sutton and Gardner 2010:1-2). Recently, the generalized use of the “Millingstone Horizon” terminology has been seen to suppress the identification of specific cultural, spatial, and temporal cultural variations that occurred over several thousand years and the coincident movement of peoples, and it is these factors that are seen to be critical to understanding prehistoric adaptation and change (Sutton and Gardner 2010:1-2). The Encinitas Tradition characteristics are abundant metates and manos, crudely made core and flake tools, bone tools, shell ornaments, and very few projectile points with subsistence focusing on collecting (plants, shellfish, etc.). Faunal remains vary by location but include shellfish, land animals, marine mammals and fish (Sutton and Gardner 2010:7). The Encinitas Tradition has been redefined to have four patterns (Sutton and Gardner 2010: 8-25). These are (1) Topanga in coastal Los Angeles and Orange counties, (2) La Jolla in coastal San Diego County, (3) Greven Knoll in inland San Bernardino, Riverside, Orange and Los Angeles counties, and (4) Pauma in inland San Diego County. About 900 B.P. Greven Knoll III groups in the Project area adopted new cultural traits that transformed them into Palomar groups. The Palomar Tradition characteristics include bow and arrow technology, new rock art styles, new settlement and subsistence systems, and Takic Dune Palms Road Low-Water Crossing Replacement Project ASR 30 languages. The Palomar Tradition is defined to have two patterns (Sutton 2011). These are the San Luis Rey Pattern in the southern California coastal area and the Peninsular Pattern in the inland areas of the northern Peninsular Ranges (e.g., San Jacinto and Santa Rosa mountains) and northern Coachella Valley. PROJECT AREA CULTURES The latest cultural revisions for the Project area define traits for time phases of the Greven Knoll Pattern of the Encinitas Tradition applicable to inland San Bernardino, Riverside, Los Angeles, and Orange counties (Sutton and Gardner 2010). This pattern is subsequently replaced in the Project area by the Peninsular Pattern of the Palomar Tradition later in time (Sutton 2011; Table 4). Greven Knoll sites tend to be in located in the inland valley areas characteristic of the Project area. These inland people apparently did not switch from the use of manos and metates to the use of pestles and mortars that is seen in coastal sites dating to approximately 5000 years ago, possibly reflecting their closer relationship with desert cultural peoples who did not exploit acorns. The Greven Knoll toolkit is dominated by manos and metates throughout its 7,500-year extent. In Phase I, other typical characteristics were pinto dart points for atlatls or spears, charmstones, cogged stones, absence of shell artifacts, and flexed position burials (Table 4). In Phase II, Elko dart points for atlatls or spears and core tools are observed along with increased indications of gathering. In Phase III, stone tools including scraper planes, choppers and hammerstones are added to the tool kit, and yucca and plant seeds are staple foods, animals bones are heavily processed (broken and crushed to extract marrow), and burials tend to be marked by stone cairns (Table 4; Sutton and Gardner 2010). Early Peninsular sites tend to be near sources of fresh water in valleys. The former Lake Cahuilla played a major role in the prehistory of the Colorado Desert. As detailed above, Lake Cahuilla formed periodically when the Colorado River broke its channel and flowed into the Salton Trough of the Coachella and Imperial Valleys, forming a large, deep body of fresh water. Sutton (2011) suggests that some San Luis Rey I people of Yuman descent split away and migrated east to the northern Peninsular Ranges and the northern Coachella Valley to exploit Lake Cahuilla, and in so doing became Peninsular I. The Peninsular Pattern then developed through the Peninsular I, II and III phases (Sutton 2011). The Peninsular I phase is marked by small points for arrows, the appearance of bedrock mortars indicating use of acorns, pottery, the appearance of shell ornaments, and pit cremations are common. Hunting and gathering of terrestrial resources and the exploitation of Lake Cahuilla’s lacustrine resources resulted in the development of new technologies for waterfowl decoys and fish traps and/or nets (Table 4). The Peninsular II phase has some important new material traits (Table 4). The Peninsular III phase reflects the archaeological signature of the ethnographic Dune Palms Road Low-Water Crossing Replacement Project ASR 31 Table 4. Cultural Patterns and Phases Phase Dates B.P. Material Culture Other Traits Greven Knoll I 8,500 to 4,000 Abundant manos and metates; Pinto dart points for atlatls or spears; charmstones, cogged stones, and discoidals rare; no mortars or pestles; and general absence of shell artifacts. No shellfish; hunting important; flexed inhumations; and cremations rare. Greven Knoll II 4,000 to 3,000 Abundant manos and mutates; Elko dart points for atlatls or spears; core tools; late discoidals; few mortars and pestles; and general absence of shell artifacts. No shellfish; hunting and gathering important; flexed inhumations; and cremations rare. Greven Knoll III (formerly Sayles complex) 3,000 to 900 Abundant manos and mutates; Elko dart points for atlatls or spears; scraper planes, choppers, and hammerstones; late discoidals; few mortars and pestles; and general absence of shell artifacts. No shellfish; yucca and seeds as staples; hunting important but animal bones also processed; flexed inhumations beneath rock cairns; and cremations rare. Peninsular I 900 to 750 Appearance of small points (Cottonwood points &, Desert Side-notched) for arrows; shaft straighteners; pottery; few stone ornaments or stone pipes; appearance of shell ornaments; use of obsidian glass from Coso, Obsidian Butte, Bagdad, and unknown sources; and use bedrock metates but few mortars and pestles. Adoption of a lacustrine-based subsistence system; movement of people into the northern Coachella Valley from the interior valleys as Lake Cahuilla filled; establishment of major residential bases along the Lake Cahuilla shoreline; and primary pit cremations. Peninsular II 750 to 300 Addition of brown ware pottery, ceramic pipes and figurines; use of same obsidian sources; and the use of stone fish traps as levels of Lake Cahuilla fluctuated and eventually declined. Lacustrine based subsistence; and the appearance of the Peninsular Funerary Complex, with secondary cremations placed in ceramic “containers” and associated mourning ceremonies. Peninsular III 300 to 150 Continued use of Cottonwood and Desert Side-notched points; brown ware and buff ware pottery; primary use of Obsidian Butte as an obsidian source; addition of new figurine types and cultigens such as melons and squash, and the introduction of Euro-American material culture (e.g., glass beads and metal tools). Adoption of terrestrial-based subsistence system; full-time villages near springs; movement of some people west into the northern Peninsular Ranges as Lake Cahuilla became desiccated; use of domesticated species obtained from Colorado River Yumans and Euro- Americans; primary pit cremation as the principal mortuary practice; and retention of mourning ceremonies. Note: Adapted from Sutton and Gardner 2010 and Sutton 2011 groups that had become established in Peninsular I and II phases with the addition of some Euro- American material culture (Table 3; Sutton 2011). Dune Palms Road Low-Water Crossing Replacement Project ASR 32 ETHNOGRAPHY By the Late Prehistoric period, the Coachella Valley was home to affiliated peoples known as the Cahuilla. They occupied the San Gorgonio Pass (referred to as the Pass Cahuilla), San Jacinto and Santa Rosa Mountains (Mountain Cahuilla), and the Coachella Valley and the northern end of Imperial Valley (Desert Cahuilla; Figure 5). The Cahuilla are linked to other Takic language family groups such as the Serrano and Luiseño, and share many aspects of culture and religion with those tribes. These peoples spoke the Cahuilla language but each person’s primary identity was linked to clan lineage and moiety, rather than tribal affiliation. The two moieties of the Cahuilla were Istam (coyote) and Tuktum (wild cat). Affiliation was inherited from the father’s moiety and members of one moiety had to marry into the other group. Each clan was an independent, politically autonomous land-holding unit (Bean 1972, 1978; Strong 1929). In addition to lineage residence areas and clan territory owned in common with other clan members, each lineage had ownership rights to various food collecting and hunting areas. Individuals also “owned” specific areas rich in plant resources, as well as hunting grounds, rock quarry locations, and sacred spots used only by shamans, healers, and ritual practitioners. Cahuilla clans varied in size from several family groups to those composed of several thousand people. Clans were generally situated so that each lineage or community was located near a reliable water source and in proximity to significant food resources. Within each community, house structures were spatially placed at some distance from each other. Often a community would spread over a mile or two in distance with each nuclear and extended family having homes and associated structures for food storage and shaded work places (ramadas) for tool manufacture and food processing. Each community also contained a house clan leader. In more recent times, a ceremonial house (kishumnawat) was placed within each community, and most major religious ceremonies of the clan were held there. In addition, house and ceremonial structures, storage granaries, sweat houses, and song houses (for recreational music) were present. Usually an area within one to three miles contained the bulk of materials needed for daily subsistence, although territories of a given clan might be larger, and longer distances were traveled to get precious exotic resources, usually found in the higher elevations of the surrounding mountains. Dune Palms Road Low-Water Crossing Replacement Project ASR 33 Figure 5. Cahuilla Territory (Heizer 1978) While most daily secular and religious activities took place within the community, there were locations at some distance from the community where people camped for extended periods to harvest acorns or piñon nuts. Throughout the area, there were sacred places used primarily for rituals, intergroup or inter-clan meetings, caches for sacred materials, and locations for use by shamans or medicine men. Generally, hilly, rocky areas, cave sites, or walled cave sites were used for temporary camping, storage of foods, fasting by shamans, and as hunting blinds. Between the mid-1500s and the 1800s, the Cahuilla were variously contacted by Spanish explorers, then Mexican ranchers, and later American settlers. By the mid-1800s, the Cahuilla were fully exposed to new peoples with new cultural ways, opportunities, and constraints. In the 1860s, several epidemics devastated the Cahuilla population and the increasing contact with Europeans continued to have a major impact on their traditional lifeway. Survivors of decimated Cahuilla clans joined villages that were able to maintain their ceremonial, cultural, and economic institutions (Bean 1978). The Cahuilla were influenced by contact with the Patayan peoples of the lower Colorado River area. The Patayan were of the Yuman language family and introduced both floodplain agriculture, the use of ceramics, and bow-and-arrow technology to the Cahuilla approximately 1500 years ago. The Cahuilla were observed by early European explorers and settlers growing small plots of corn, pumpkin, melon, watermelon, barley, and wheat where there were reliable water sources (Schaefer and Laylander 2007: 253). Dune Palms Road Low-Water Crossing Replacement Project ASR 34 HISTORICAL SETTING The Cahuilla retained control of their ancestral lands longer than most California tribes did, as they were somewhat distant from the established Spanish Missions. The first regular incursion into Cahuilla territory was Hank Brown’s wagon road in the 1850s along what is now the route of Interstate 10 (Lech 2004:137-8). Because of competing economic and political considerations, however, it was not until the mid- 1870s that a serious push to settle the Coachella Valley occurred when the Southern Pacific Railroad transected the western Colorado Desert through the Coachella Valley. This route connected the San Gorgonio Pass to the town of Yuma, Arizona, via the eastern shore of the Salton Sink. Within a decade, the Federal Government gave all the odd-numbered sections of land in the Coachella Valley to the Southern Pacific Railroad, which completed its line through the desert to the Pacific Ocean in 1877. The Southern Pacific later became the Union Pacific Railroad. When President U.S. Grant established the Cahuilla Indian Reservations beginning in 1875, only the even-numbered sections were still available, thus creating the present Reservation checkerboard pattern. At the same time, ancestral Cahuilla lands were being granted to American settlers and Cahuilla peoples were being moved onto reservations (Agua Caliente Band of Indians n.d.). Development was very slow and towns were small until relatively recently; however, residential and commercial development is reaching new peaks during the current decade (Lech 2004:142). GEOARCHAEOLOGICAL SENSITIVITY ANALYSIS METHODS The United States Department of Agriculture (USDA) National Resources Conservation Service (NRCS) soils map and descriptions (accessed September 2016) and geologic maps (Figure 6) were utilized for this assessment. Using the USDA NRCS maps, the APE was mapped for soils (Figure 7). The most recent soil descriptions provided by the NRCS (accessed November 2016) were utilized for this assessment. Subsurface site preservation depends on many factors. Soils and locations were analyzed for grain sizes, slope, and environmental indicators that contribute to the preservation of sites. Primarily sites accumulate where people have the highest probability of living; on lower slope gradients near water sources but in areas that are unlikely to experience regular flooding. Additionally, lower slope gradients decreases erosion and increases deposition assisting in site burial. Both pebbly and coarser grain sizes as well as clay rich soils preserve artifacts poorly. The age of a soil also determines the likelihood of buried archaeological sites and must be assessed as the older soils are less likely to contain sites unless items were intentionally buried in them. Soils likely too old for site preservation have duripans (hardpans), and argillic (clay rich) Dune Palms Road Low-Water Crossing Replacement Project ASR 35 Figure 6. Project Geology Dune Palms Road Low-Water Crossing Replacement Project ASR 36 Figure 7. Project Geomorphology Dune Palms Road Low-Water Crossing Replacement Project ASR 37 horizons; while younger soils with a higher potential for preservation are indicated by the lack of a B horizon or the presence of a cambic horizon. Both Holocene alluvial and aeolian units have a higher potential for artifacts as the soils were co-deposited with the local cultural groups. Classifications for buried site potential are as follows: Very low: Soils are underlain by deposits that predate human occupation of the region. The soils that include B, argillic or silicic (duripan) horizons. Additionally exposed bedrock, borrow pits, heavily eroded or gullied land, or water bodies have a very low potential. Areas of high erosion, water, borrow pits, rock outcrops or sediments mapped as Pleistocene or older are also classified as having a very low potential. Low: Soils are underlain by deposits that predate human occupation of the region, high-energy deposits unlikely to contain cultural materials in a primary context, are residual soils (soils weathered in place above bedrock), or include B horizons. Low-potential areas include Inceptisols. Although these soils commonly have a higher probability for buried sites, Inceptisols are formed in residual soils weathered directly from bedrock and, thus, have a low potential for buried sites. Areas where soils are weathered from bedrock, dissected alluvial fans and locations where soils are forming on mountains are classified as having a low potential. Medium: Soils are underlain by deposits that are most likely terminal Pleistocene or Holocene in age, possibly have intact buried surfaces, or have sediments that are likely to have been deposited in a low-energy environment. Alluvial fans, fan aprons, valley fills, dissected remnants of alluvial fans, floodplains, and drainages are classified as having a medium potential. High: Soils are underlain by deposits that are most likely terminal Pleistocene or Holocene in age, or sediments represent low-energy deposits, or have a high potential to contain buried intact geomorphic surfaces that could have been used by humans in the past. Alluvial stream terraces and floodplains, terrace escarpments, alluvial fans (fan skirts, fan aprons, and inset fans), and areas with aeolian deposits are classified as having a high potential. RESULTS Using the produced soils maps and resources above, soils were classified as having a very low, low, medium or high potential to contain buried sites (Table 5). The APE within the Coachella River bed is mapped as Holocene gravels (Qg) and Coachella fine sand with a 0%-2% slope gradient. Outside of the channel the APE is mapped as Holocene dune sands and alluvium (Qd, Qa) and as Myoma fine sand with a 5%-15% slope gradient. The Coachella series is a sandy, mixed, hyperthermic Typic Torrifluvents soil (Entisol) with C1 to C5 horizons. Coachella soils are light olive gray fine sand and very fine sand with thin strata Dune Palms Road Low-Water Crossing Replacement Project ASR 38 of silt loam or very fine sandy loam to a depth of 60 inches (USDA Soil Series Description, accessed November 2016). The Myoma series is a mixed, hyperthermic Typic Torripsamments soil (Entisol) with C1 to C4 horizons. Myoma soils are typically light olive gray, moderately alkaline, fine and very fine sands to a depth of about 31 inches. Below 31 inches they are strongly alkaline very fine sands. The control section has less than 15 percent coarse fragments and less than 15 percent of coarse and very coarse sand. The profile throughout is moderately to strongly alkaline with slight to violent effervescence (USDA Soil Series Description, accessed November 2016). While approximately the same age, the Coachella fine sand has a low potential for buried sites as it lies within the Coachella River bed. Sites in areas that have strong erosion such as flash flood areas have lower potential. The Myoma fine sand through the rest of the APE is assigned a medium potential.

PROJECT AREA HISTORY The historical settlement pattern is reflected in land patents granted by the Government Land Office, which show that the Southern Pacific Railroad Company was granted patents in 1866 and the State of California in 1927 (BLM n.d.). The 1904 USGS topographic quadrangle, the earliest available, shows no development or any other features near the APE with the exception of the Whitewater River. Highway 111 and Dune Palms Road are first depicted on the 1941 Toro Peak USGS 15’ quadrangle. The Trailer Park [Dune Palms Mobile Estates (parcel 600-030-010)] adjacent to the northeast APE is first shown on the 1973 La Quinta USGS 7.5’ quadrangle; Dune Palms Road Low-Water Crossing Replacement Project ASR 39 however, buildings first appear in this area in the 1959 La Quinta USGS 7.5’ quadrangle (Figure 8). The APE and the immediate area around it shows no other signs of development until USDA aerial photographs show the presence of La Quinta High School by 1996, a USA Gasoline Station on the northwest corner of the intersection of Highway 111 and Dune Palms Road by 2002, and the La Quinta Corporate Centre by 2005. The City of La Quinta began as a “watering hole” for gold miners traveling through the Coachella Valley along the on their way to Arizona. In 1862, Major William Bradshaw transported miners through the Valley and stopped at Point Happy (corner of Washington Street and Highway 111) which soon became a way station for stagecoaches and freight wagons traveling the Bradshaw trail (Soltys 2005:175). In 1926, Walter Morgan founded the La Quinta Resort which attracted Hollywood celebrities and established La Quinta as a resort destination for Los Angeles’ wealthy population. The City of La Quinta, named for the Resort, was incorporated in 1982 and maintains a seasonal population and reputation as a premier resort town (City of La Quinta 2014). PREVIOUS GROUND DISTURBANCE WITHIN THE PROJECT AREA Cogstone reviewed the Coachella Valley Stormwater Channel Plan and Profile and the Off-site Improvement Plan for the LA Quinta Corporate Centre, both provided by the City’s design consultant, as well as historic topographic maps (Figure 8) and historic aerials (Figures 10-13) in order to understand to what extent previous disturbances had occurred within APE. The information from these two plans was geo-referenced and overlain on the APE map (Figures 9 and Appendix C-2). Additionally, aerial photography available on Google Earth was reviewed. Finally Brad Donais, Senior Project Manager for Heptagon Seven, provided additional information regarding the extent of construction disturbances as a result of the channelization of the Whitewater River and the installation of sewer pipes (personal communication, 2016). Specific construction disturbances to the APE include residential construction, roads, and commercial structures. These disturbances are briefly discussed here according to the date in which they occurred: • 1940s: The Dune Palms Mobile Homes Estates (APN 600-030-010) was built in or shortly after 1949, according to a classified advertisement in The Desert Sun (1949:13). Dune Palms Road was also constructed at this time. • 1950s: Disturbances postdating the construction of the Dune Palms Road and Dune Palms Mobile Homes Estates occurred in APNs 600-030-004, 600-030-021 and 600-030- 020, when three houses were constructed in the late 1950s. These are not visible on the 1954 Palm Desert 15 min. USGS quadrangle topographic map but do appear on the 1959 La Quinta 15 min. USGS quadrangle topographic map (Figure 8). Although all were Dune Palms Road Low-Water Crossing Replacement Project ASR 40 extant through at least 2006, only the northernmost of these remained by 2009, and it was demolished by the following year (Figures 10 & 11). • 1950s-2000s: The Whitewater River was channelized by the Coachella Valley County Water District (CVCWD) in order to better manage storm water run-off (CVCWD 1971), a project which, judging by historic USGS topographic quadrangle maps, began in the 1950s (Figure 8). The channelization process included the building up of the dirt side walls with portions of the walls concreted over (Figure 9). • 1970s-1990s: The sidewalk along the west side of Dune Palms Road was added after 1972 but prior to 1996 (National Environmental Title Research 2016). It was likely constructed in conjunction with the building of La Quinta High School. The school is just west of the sidewalk and outside the APE and was constructed between 1994 and 1996 (Figure 10). Ground disturbance also occurred along the western edge of the APN 600- 030-018 when Dune Palms Road was extended north from Highway 111 between 1996 and 2002 (Figures 12 & 13). • 1999-2001: Further disturbance within the APE occurred during the construction of the La Quinta Corporate Centre, located at Highway 111 and Dune Palms Road on APNs 600-390-007, 690-390-021 and 690-390-023 (Figures 9-13). CRM Tech carried out a testing and evaluation plan of P-33-08692 (CA-RIV-6190), located on the aforementioned APNs, and P-33-16950 (CA-RIV-8835, located on APN 600-030-018, in 2000. A 12 inch sewer line was installed within APN 600-030-018. Details of the disturbance the installation of the sewer line and its effects on site located, is described in the next section. • 2000s: A borrow pit, measuring approximately 24 m in diameter and from 40 cm to 1.37 m in depth, is located within APN 600-030-021 and must have been excavated after 2009, when the last house on the parcel was demolished (see discussion of 1950s disturbances, above), and prior to the 2014 survey. The Kingdom Hall of Jehovah Witnesses located on APN 600-030-019 was constructed between 2002 and 2004 (Figure 13). With the building of the Jefferson Plaza Shopping Center to the east of APN 600- 030-018 sometime between 2006 and 2009, the concreted walls of the Whitewater River channel were extended west (Figures 10 & 11). Dune Palms Road Low-Water Crossing Replacement Project ASR 41 Figure 8. 1959 Historic USGS Topographic Map SEWER LINE DISTURBANCES TO SITE P-33-16950 (CA-RIV-8835) APN 600-030-018 In addition to the channelization of the Whitewater River, site P-33-16950 (CA-RIV -8835) has been effected by the installation of a 12 inch sewer main in 2000 for the La Quinta Corporate Centre located across the street on the west side of Dune Palms Road (La Quinta Corporate Centre 2000). The sewer pipe runs south of the stormwater channel and east of Dune Palms Road, from Corporate Center Drive north to the southern bank of the CVSC, then turning east parallel with the channel. Table 6 depicts the depth below existing ground of the installed sewer main. In those areas where Dune Palms Road Low-Water Crossing Replacement Project ASR 42 the depth of the sewer was greater than five (5) feet between the bottom of the pipe trench and existing ground, the pipe trenching would have required a minimum slope of a 1.5:1 slope from a point five (5) feet above the bottom of the pipe, with the lower five (5) feet being excavated close to vertical sides of the trench. The depth of sewer main at the four manholes located within the Project Area along with the estimated excavation limits for the sewer trench excavation limits are summarized below. In addition to the above noted excavation limits, visual evidence of the current site condition indicates that the sewer construction operations utilized the area to the south of the sewer line for staging, through either the temporary placement of trench material and/or as a path of travel for the construction equipment. The undisturbed portions of parcel 600-030-018 contain natural rolling mounds and scattered scrub brush. These features are absent from the disturbed areas indicating prior earth moving activities. Table 6. Depth of Manholes constructed for the CVSC Location Manhole Depth Construction Trench Half Width 1 Dune Palms/Corporate Ctr. Intersection 14.75 ft 17.0 ft Dune Palms @ Channel South Side 7.15 ft 5.5 ft ~262 ft east of Dune Palms along channel 11.39 ft 12.0 ft ~462 ft east of Dune Palms along channel 13.32 ft 14.5 ft Through the use of historical and current aerial photography, the previously disturbed limits are approximately 40 feet east of the edge of the existing Dune Palms Road and approximately 120 feet south of the top of the storm water channel into the existing vacant commercial site. Based on all of the data gathered from previous archaeological research, prior disturbances and the survey, it is evident that P-33-08692 (CA-RIV-6190) is likely destroyed and the portion of P- 33-16950 (CA-RIV-8835) within the APE has been disturbed and the possibility of intact sub- surface cultural features within the area of direct impact and its sensitivity is unknown. 1 Trench Half Width is half the width of the trench excavation necessary for the placement of the sewer line, measured from the centerline of the pipeline.

Previous Construction Disturbances, Historic Aerial 2002 (Google Earth 2015) Dune Palms Road Low-Water Crossing Replacement Project ASR 48 FIELD SURVEY METHODS AND RESULTS On December 29, 2014 Lindsey Porras, Cogstone Staff Archaeologist, completed an intensive- level pedestrian survey of the APE as it was then delineated. Ms. Porras surveyed the entire APE with the exception of the Dune Palms Mobile Estates development due to access limitations. The survey consisted of walking parallel transects, spaced at no greater than 15-meter intervals within the APE while closely inspecting the ground surface. Existing disturbances (e.g., rodent burrows, cut banks) were examined for artifacts or buried cultural deposits. Digital photographs were taken to document environmental conditions. Subsequent to the initial survey and in consultation with Caltrans, Desiree Martinez, Cogstone Principal Archaeologist, returned to the Project Area on June 23, 2015 to gain a better understanding of the disturbances that had occurred on APNs 600-030-018 and 600-030-019. On July 7, 2015, Martinez met with Steven Holm (Caltrans Cultural Studies Archaeologist), Gabrielle Duff (Caltrans Branch Chief Cultural Studies), Aaron Burton (Caltrans Senior Environmental Planner), and Brad Donais (Senior Project Manager, Heptagon Seven representing the City of La Quinta) on-site to review the project and to discuss the construction activities that would occur within the APNs and how they may affect P-33-16950 (CA-RIV- 8835). The site visit prompted an expansion of the APE to include entirety of APNs 600-030-018, 600- 030-019, 600-030-020, 600-390-021, 600-030-004, 600-030-010, 600-030-021, 600-390-010, 600-390-007 and 600-390-023. Martinez surveyed these additional areas by walking parallel transects, spaced at no greater than 10-meters within the APE while closely inspecting the ground surface. Existing disturbances (e.g., rodent burrows, cut banks) were examined for artifacts or buried cultural deposits. Digital photographs were taken of each parcel to document environmental conditions. Weather was clear, slight breeze with temperature recorded at 105º. Ms. Martinez was at that time able to access all the new portions of the APE except for the Dune Palms Mobile Estates development. The development was accessed by L. Furnis on August 6, 2016 during the survey for the Historical Resources Evaluation Report (HRER) and is discussed in that document (Furnis 2015). In general, the APE consists of the hardscaped Dune Palms Road between Highway 111 and Westward Hoe Drive along with adjacent parcels. Ground visibility within the paved areas was zero. In the unpaved areas of the APE, ground visibility ranged from excellent (80-100%) to poor (10%). Moderate visibility occurred near the Whitewater River because of the presence of overgrown vegetation. Each parcel exhibits slightly different environmental, visibility and previous disturbance characteristics; therefore, the survey results are described by parcel number. Dune Palms Road Low-Water Crossing Replacement Project ASR 49 APN 600-030-004 APN 600-030-004 is a vacant lot located at 46160 Dune Palms Road. Visibility was 90% and sediments are wind-blown silty sand with 15% small cobbles and pebbles. Portions of the parcel were covered with a reddish hard clay crust possibility from construction that occurred on adjacent parcels (Figure 14). A Southern California Edison pole # 995270 is located in the western portion of the parcel. Pedestrian disturbance is evident by modern trash. No cultural resources were identified. APN 600-030-010 The Dune Palms Mobile Estates is located on APN 600-030-010 at 46400 Dune Palms Road. This property was surveyed by Lynn Furnis and is discussed in detail in the HRER (Furnis 2016). No historic properties were discovered within the parcel and the property itself was evaluated and recommended to be not eligible for listing on the NRHP or CRHR. APN 600-010-009 Ground visibility was excellent (90 %). There is little vegetation within the bed of the Whitewater River (Figure 15), except in clusters near to where Dune Palms Road crosses the wash (Figure 16). The survey of this parcel was positive for cultural resources: one ceramic sherd was located. Figure 14.

Typical Area with Excellent Visibility, Facing South at Whitewater River, on December 29, 2014 Figure 16. Overgrown Vegetation at Whitewater River, Facing East, on December 29, 2014 APN 600-030-018 Dune Palms Road Low-Water Crossing Replacement Project ASR 51 The survey of APN 600-030-018 was positive for cultural resources; previously recorded site P- 33-16950 (CA-RIV-8835) was re-identified and additional material recorded. The finds were aided by the excellent (90%) ground visibility as there is little vegetation on this vacant lot. The field survey discovered that the site extended further north of the previously documented boundaries (Figures 17, 18, Appendix C-6, and Appendix C-7). The additional cultural materials included a ceramic scatter consisting of seven brownware sherds as well as one chert secondary flake. Four GPS points were taken as an example of the sherds’ location. Although Cogstone identified cultural material on the surface within the APE and extended the boundary of P-33-16950 (CA-RIV-8835) to include the material, it was evident that extensive ground disturbance had occurred. As a result, it is not clear if there were intact subsurface cultural matrix extending into the APE or if the material was being brought into the APE by previous grading, disking, utility installation and/or construction activities. As a result, Desiree Martinez, Cogstone Principal Archaeologist, revisited APN 600-030-018 on June 23, 2015 to further investigate the ground disturbance, to relocate the artifacts identified in the initial survey and assess whether the artifacts were in a primary context. Figure 17. Ceramic Scatter in APN 600-030-018, on December 29, 2014 Dune Palms Road Low-Water Crossing Replacement Project ASR 52 Figure 18. Rim Profile of Brownware Sherd in APN 600-030-018, on December 29, 2014 The ceramic scatter located at GPS point B by Porras was re-identified and collected (20150623DRM12). Martinez and Porras used different GPS units to collect UTM coordinates which resulted in a 5 ft error. As a result Martinez cannot verify that the ceramic pieces collected were the same ones identified at GPS point A. Martinez also collected 56 brownware ceramic sherds and 1 shaped ceramic artifact in order to get a sampling of the types of ceramics within the scatter in the expanded site boundaries (Table 7; Figures 19 and Appendix C-7). Also collected were 25 fire-hardened clay pieces, which at the time were thought to be fired daub (Figure 20 & 21). CRM Tech (2008) cataloged similar items as daub/FAC during their testing phase. All of the artifacts were located on sediments described as silty fine-grained sand with 10 percent pebbles and granules. Photos of the fire-hardened clay pieces were sent to colleague Ivan Strudwick for review. Strudwick, a California archaeologist, had previously conducted research on fired clay daub recovered from prehistoric California sites (Strudwick 2005). Strudwick stated that they were not fired daub since they lacked organic material within the paste and do not have any impressions of twigs, sticks or structure poles as one would see in true fired daub. He suggested that the pieces could be fire-hardened clay from a clay-lined hearth similar to what he has seen in the Central Valley (Strudwick, personal communication 2015). This theory needs to be investigated further. Dune Palms Road Low-Water Crossing Replacement Project ASR 53 Table 7.

This may be the result of the ground disturbance that has occurred since the December 29, 2014 survey. There is a dirt access road that parallels the location of the VCP sewer line on the southern side of the Whitewater River Storm Water Channel. The sewer access road had been graded within the last six months (Figure 22). Additionally, sometime after the grading of the access road, it rained heavily enough to cause small erosion channels near the location of the artifacts (Figure 23). Throughout APN 600-030- 018 there is evidence of construction dumping, including large chunks and small pieces of asphalt, chunks of concrete slabs and structures as well as soil berming (Figures 24-26). No intact features or human remains were identified during the re-visit. The ceramic artifacts varied widely in thickness and color indicating that they were from different vessels and were therefore likely collected and redeposited at an unknown date (Figure 27). Additionally, although the artifacts found at GPS points C & D were not re-identified, based on the documentation of the ground disturbance that has occurred historically within APN 600-030-018 and the more recent ground disturbance that was documented during the re-visit, it is evident that those artifacts were also in a secondary context. The site boundaries of P-33-16950 (CA-RIV-8835) were expanded northwesterly to include the ceramic scatter (Appendix E). Dune Palms Road Low-Water Crossing Replacement Project ASR 56 Figure 22.

Martinez conducted a survey of the area; two buildings sit on the parcel. Eighty percent of the parcel is hardscaped with asphalt and concrete, leaving just 20 % of the ground surface visible. The islands between parking spaces were covered with vegetation (bushes and trees) and show evidence of previous disturbance by the installation of electrical lighting and irrigation. The sediments were silty sand. No cultural material was identified (Figures 28 & 29). APN 600-030-020 APN 600-030-020 is a vacant lot located at 46150 Dune Palms Road. Visibility was 95% and sediments are wind-blown silty sand with 15% small cobbles and pebbles. Portions of the parcel are covered with a reddish hard clay crust. Pedestrian disturbance is evident by modern trash. No cultural resources were identified (Figure 30). Figure 28.

Visibility was 97% and sediments were wind-blown silty sand with 15 % small cobbles and pebbles. An isolated granitic mano (20141229LAP_1) was found within this of the APE (Figures 31 & Appendix C-6, Appendix E). Portions of the parcel were covered with hardened reddish clay possibly from construction that occurred on adjacent parcels (Figure 32). On the western edge of the parcel, there is a borrow pit area measuring approximately 24 m in diameter and 40 cm to 1.37 m in depth (Figure 33). Pedestrian disturbance is evident by modern trash throughout the parcel. One tree is located in the middle of the parcel and a cluster or trees on the western edge. No other cultural material was found at this location. Figure 31.

No cultural material or features were observed. APN 600-390-010 A USA Gasoline station is located on APN 600-390-010 at 79490 Highway 111. Seventy-five percent of the area was hardscaped with asphalt and concrete, with 25 % ground visibility. Martinez surveyed the tree/flower beds that surrounded the south and east sides of the parcel; the sediments were silty sand. The flower/tree beds had evidence of disturbance from the installation of sprinklers. Vegetation included palm trees and low desert shrubs. No cultural material or features were observed (Figure 34).

Dune Palms Road Low-Water Crossing Replacement Project ASR 66 STUDY FINDINGS AND CONCLUSIONS Two previously recorded archaeological sites were identified within the APE during the records search. These sites were P-33-08692 (CA-RIV-6190) and P-33-16950 (CA-RIV-8835). One isolate (20141229LAP_1) was found during the cultural resources survey of the APE and DPR forms have been drafted. According to January 2014 First Amended Programmatic Agreement Among the Federal Highway Administration, the Advisory Council on Historic Preservation, the California State Historic Preservation Officer, and the California Department of Transportation Regarding Compliance with Section 106 of the National Historic Preservation Act, as it pertains to the Administration of the Federal-Aid Highway Program in California (PA) “Isolated prehistoric finds consisting of fewer than three items per 100 square meters” are exempted from evaluation; therefore, 20141229LAP_1, a granitic mano, does not require further consideration. P-33-08692 (CA-RIV-6190) is located within the southwest portion of the APE mapped, to the west of Dune Palms Road. It was previously recorded as a 230 m by 170 m prehistoric habitation site with six loci of ceramics, burned faunal bone, debitage, burned clay, and fire affected rock. Although no human remains were positively identified, 23 fragments were considered possibly human due to their consistency with human cremations in the region. Based on a jasper Cottonwood Triangular projectile point and Salton Buffware ceramic fragments recovered, the site is a late prehistoric Cahuilla habitation site less than 1000 years old (Love et al. 1998). Based on the testing and monitoring results, Love (2000) stated that the research potential of the site was exhausted and recommended that the site not be considered eligible for the National Register of Historic Places (NRHP) or the California Register of Historical Resources (CRHR). P-33- 08692 (CA-RIV-6190) was not re-identified during the survey because the area has since been developed with several businesses currently occupying its location. Site P-33-16950 (CA-RIV-8835) is located in the southeastern portion of the APE, to the east of Dune Palms Road and was previously recorded as a 145 m by 130 m light prehistoric ceramic scatter with daub and fire affected rock in 2008. Archaeological subsurface testing and evaluation was conducted which included the hand excavation of eight 1 m by 1 m or 1 m by 2 m TUs, twenty-three 50 cm by 50 cm STPs. Two trenches measuring 10 m by 2 m and three 2 m by 1 m were excavated by backhoe. The TUs were excavated to 1 m below ground surface (cmbs), STP depth ranged from 50 cmbs to 100 cmbs, while the backhoe trenches and pits were excavated to 150 cmbs or 250 cmbs. Seven hundred and fourteen artifacts (e.g. prehistoric ceramic sherds, daub/fire affected clay, groundstone fragments, and rocks) were recovered during surface collection prior to testing. Seven hundred and twelve artifacts consisting of ceramic sherds, marine and freshwater shell, Dune Palms Road Low-Water Crossing Replacement Project ASR 67 groundstone, charcoal, faunal bone and human remains were recovered from the TUs. Additionally, twenty-seven 1 m by 1 m recovery units (RUs) were hand excavated around the location of the human remains resulting an additional 1,125 artifacts and ecofacts. The depth of the RUs ranged from 20 cmbs to 40 cmbs. Based on the testing program, CRM Tech concluded that the site in general had “very limited ability to provide important new information for the study of prehistory in the Whitewater River Delta/ Dune Complex and surrounding region, [and] in light of the low quantity of formal artifacts it yielded… the site as a whole does not appear to qualify as a ‘historical resource’." However CRM Tech also stated that since the cremated human remains retain a high degree of Native American traditional cultural value, the portion of the site containing the cremation remains was determined to meet CEQA's definition of a "historical resource” (Eddy et al. 2008). Although the testing program at P-33-16950 (CA-RIV-8835) identified artifacts at 250 cm in depth, the type and quantity of artifacts were not listed in the report. Cogstone obtained a copy of the original catalog which shows that a majority of the artifacts were found in the upper 40 cm (1.3 ft) of the site. Sixteen items were found between 100 cm and 250 cm in depth. These items included 6 pieces of fire affected clay, 1 piece of unburned sandy clay, 5+ pieces of unburned clay, 1 faunal bone fragment, and 3 pieces of charcoal. P-33-16950 (CA-RIV-8835) was re-identified during the current survey and its boundaries extended to the northwest to include a newly identified ceramic scatter. This extension constituted 550 m2 of additional area making the total area of the site 12,168 m2. The geoarchaeological analysis in the Background Section indicates the potential for buried archaeological deposits ranges from low to medium potential. Areas of low potential are located within the Coachella River bed. The rest of the APE is assigned a medium potential for buried archaeological deposits. Within the medium potential areas, ground disturbing activities include reconstructing the north and south bridge approaches to accommodate the significant raised profile of the road. Minor grading will be required to prepare the existing ground to accept the fill material necessary to accommodate the proposed profile grade. The typical maximum vertical excavation of the APE within the medium potential area is 1 foot in undisturbed areas outside of the existing street right of way section (west of Dune Palms and south of the stormwater channel). The maximum vertical depth of the APE within the existing roadway street right of way section and within previously disturbed areas (mobile home park) is a maximum of 4 feet. Additional research was conducted to understand the extent of previous disturbances affecting the integrity of P-33-16950 (CA-RIV-8835) within the APE. Data suggests that the possibility of intact subsurface features varies across the site and cultural sensitivity is unknown. As a result, the impacts to the site are unknown. Dune Palms Road Low-Water Crossing Replacement Project ASR 68 It is Caltrans' policy to avoid cultural resources whenever possible. Further investigations may be needed if the site[s] cannot be avoided by the Project. If previously unidentified cultural materials are unearthed during construction, it is Caltrans' policy that work be halted in that area until a qualified archaeologist can assess the significance of the find. Additional archaeological survey will be needed if Project limits are extended beyond the present survey limits. Further, if human remains are unearthed during excavation, State Health and Safety Code Section 7050.5 states “there shall be no further excavation or disturbance of the site or any nearby area reasonably suspected to overlie adjacent remains until the coroner of the county in which the human remains are discovered... [has made the appropriate assessment, and] …recommendations concerning the treatment and disposition of the human remains have been made to the person responsible for the excavation, or to his or her authorized representative, in the manner provided in Section 5097.98 of the Public Resources Code.” Dune Palms Road Low-Water Crossing Replacement Project ASR 69 REFERENCES CITED Agua Caliente Band of Indians n.d.

SITE RECORDS State of California  The Resources Agency Primary # P-33-16950 DEPARTMENT OF PARKS AND RECREATION HRI# CONTINUATION SHEET Trinomial CA-RIV-8835 Page 1 of 7 *Resource Name or # P-33-16950 CRM Tech first recorded site P-33-16950 16950 (CA-RIV-8835) during Phase I survey in February 2008. At that time, the site was recorded as a prehistoric scatter of daub, ceramic sherds, and fire affected rock. Significance and the vertical extent of the site could not be determined and CRM Tech recommended a testing and evaluation program (Eddy et al. 2008). In April of 2008, CRM Tech conducted a Phase II testing and evaluation program. The Phase II study was conducted with the purpose of determining the historical significance of the site according to guidelines established by the California Environmental Quality Act (CEQA). The CRM Tech study consisted of a re-survey of the site, surface collection of artifacts, and multiple excavations. Testing included the hand excavation of 8 test units (TUs) measuring 1meter by 1 meter (m) or 1 m by 2 m, twenty-three 50 centimeter (cm) by 50 cm shovel test pits (STPs), as well as two backhoe excavated trenches measuring 10 m by 2 m and three 2 m by 1 m backhoe excavated pits. The TUs were excavated to a 100 cm below ground surface (cmbs), the STP depth ranged from 50 to 100 cmbs, while the backhoe trenches and pits were excavated to 150-250cmbs. The depth of the RUs ranged from 20 to 40 cmbs. Survey and excavation resulted in the recovery of approximately 2651 artifacts the majority of which consisted of daub/fire affected clay, rock, and faunal remains. Sixty-four ceramic sherds, 15 lithic artifacts, three groundstone fragments, and 10 shell fragments were also recovered. Importantly, 88 specimens were positively identified as human and an additional 83 specimens identified as probable human. The human remains were the result of a cremation burial and were poorly preserved. CRM Tech determined that the site as a whole did not meet CEQA significance criteria: therefore, it did not qualify as a historical resource. However, CRM Tech noted that the area containing the cremation burial retains a high degree of traditional cultural value to the local Native American community and therefore meets CEQA criteria as a historical resource (Eddy et al. 2008:45; Ballester and Eddy 2008:3). In December of 2014, Lindsay Porras, an archaeologist with Cogstone Resource Management (Cogstone), conducted archeological survey of portions of parcels 600-030-018 and 600-010-009 as part of the Dune Palms Road Low-water Crossing Replacement Project proposed by Caltrans and the City of La Quinta. The survey resulted in the documentation of a light ceramic scatter directly northwest of the recorded boundaries of site P-33-16950. The scatter included seven brownware sherds as well as one chert secondary flake. The presence of the ceramic scatter in the close proximity to P-33-16950 necessitated a northwesterly expansion of the site’s boundaries. This expansion contains an area of 2180.82 square meters, of which 258 are within parcel 600-010-009. None of the artifacts were collected during the survey. Although Cogstone identified cultural material on the surface and extended the boundary of P-33-16950 (CA-RIV- 8835) to include the material, it was evident that extensive ground disturbance had occurred. As a result, it was not clear if there was intact subsurface cultural matrix within the new extended boundary or if the material was being brought into the area by previous grading, disking, utility installation and/or construction activities. Additional research was conducted in order to understand to what extent previous disturbances within APN 600-030- 018 may have affected the distribution of cultural materials from P-33-16950 (CA-RIV-8835). Cogstone reviewed the Coachella Valley Stormwater Channel Plan and Profile and the Off-site Improvement Plan for the La Quinta Corporate Centre, both provided by the City of La Quinta. Additionally, aerial photography available on Google Earth was reviewed. The Whitewater River was channelized by the Coachella Valley County Water District (CVCWD) in order to better manage storm water run-off (CVCWD 1971). This included the building up of the dirt side walls with portions of the walls concreted over. With the building of the Jefferson Plaza Shopping Center to the east of APN 600-030-018 sometime between 2006 and 2009, the concreted walls of the channel were extended west. Ground disturbance also occurred along the western edge of the APN 600-030-018 when Dune Palms Road was extended north from Highway 111 between 1996 and 2002 (Figures 15 & 16). In 2000, 8” and 12” vitrified clay pipes (VCP) for a sewer line were installed for the La Quinta Corporate Centre located across the street on the west side of Dune Palms Road. The VCP sewer line was placed approximately 20 feet south of the storm water channel. This included excavation from 7ft to 14 ft below surface (La Quinta Corporate Centre 2000). With the new information obtained about prior disturbances, Martinez revisited APN 600-030-018 on June 23, 2015 to further investigate the ground disturbance, to relocate the artifacts identified in the initial survey and assess whether the artifacts were in a primary context. *Recorded by: Lindsey Porras *Date: 12/29/2014  Continuation  Update DPR 523L (1/95) State of California  The Resources Agency Primary # P-33-16950 DEPARTMENT OF PARKS AND RECREATION HRI# CONTINUATION SHEET Trinomial CA-RIV-8835 Page 2 of 7 *Resource Name or # P-33-16950 The ceramic scatter located at GPS point B by Porras was re-identified and collected (20150623DRM12). Martinez and Porras used different GPS units to collect UTM coordinates which resulted in a 5 ft error. As a result Martinez cannot verify that the ceramic pieces collected were the same ones identified at GPS point A. Martinez also collected 56 brownware ceramic sherds and 1 shaped ceramic artifact in order to get a sampling of the types of ceramics within the scatter in the expanded site boundaries. Also collected were 25 fire-hardened clay pieces, which at the time were thought to be fired daub. CRM Tech (Eddy et al. 2008) cataloged similar items as daub/fire affected clay (FAC) during their testing phase. All of the artifacts were located on sediments described as silty fine-grained sand with 10 percent pebbles and granules. In 2008, CRM Tech estimated the area of P-33-16950 at 3690 square meters. In December of 2014, Cogstone measured the area utilizing ArcGIS and found the original estimate to be in error. The area of the site as recorded in February of 2008 equaled 9255m2. The updated boundaries of April 2008 equaled 9987m2. The area of the site with the 2014 update totals 12168m2. The site was not evaluated for its eligibility for listing in the National Register of Historic Places or the California Register of Historical Resources. Subsurface testing in the extension area is required to make the determination.

However, no obvious or definite evidence of features, s u ch as fire pits or house rings, was found . The vertical extent of site CA-RIV-8835 and its potential for containing intact subsurface artifact deposits and features could not be ascertained on the basis of the 2008 Phase I survey (E n carnarcion and Hogan 2008: 13-14). Therefore, a testing and evaluation program was recommended to assess the historical significance of the site. In April 2008 , CRM TECH completed the field procedures for the testing program at the site. In April 2008, variety of recovery methods were used to collect data from site CA-RIV-8835, including a systematic re-survey, surface collection, shovel test pits (STPS), test units, backhoe trenching, backhoe test pits, and recovery units. All artif a cts and ecofacts recovered from CA-RIV-8835 were transported to CRM TECH's laboratory for further detailed analysis. The re-survey of site CA-RIV-8835 found additional surface artifacts, including ceramic sherds, marine a n d freshwater shell, groundstone, and faunal that were not observed during the previous s u rvey . This resulted in a slight expansion of the boundaries of the site . The surface area of the site now covers approx imately 3,690 square meters. The site was subsequently organized into areas of relatively dense artifact concentrations, small artifact clusters, and sparse artifact scatters. Although sparse scatters of daub/FAC typically characterized the surface deposit at the site, there were several areas where artifacts appeared to cluster in relatively dense concentrations. During the surface collection, a total of 714 artifacts and ecofacts, including prehistoric ceramic sherds, daub/FAC, grounds tone fragments, and rocks, were collected from five artifact concentrations and the sparsely scattered areas of the rest of the site . A total of eight test units, seven measuring 1x1 meter and o n e measuring 1x2 meters, were excavated to the depths of 50-100 cm below ground surface. Approximately 712 artifacts, including daub/FAC, ceramic sherds, lithics, freshwater shell, charcoal, rock, and faunal, including cremated human remains, were recovered from the test units. Most significantly, cremated human remains were discovered in Unit 5, placed where non-diagnostic bone fragments were found on the surface o f Concentration 4 during the re-survey.

Under more favorable conditions, analysis of the types of artifacts found at CA- RIV-8835, including daub/FAC, ceramic sherds, lithics, groundstone, FAR, shell, faunal, and human remains, could yield important information on prehistoric life in the Whitewater River Delta/Dune complex and near the northwest shoreline of ancient Lake Cahuilla. However, in light of the low quantity of formal tool artifacts and production debris, the absence of dense cultural midden, and the relative homogeneity of the material assemblage, Site CA-RIV-8835 have a very limited ability to provide any new information of importance to the results of numerous previous studies in the vicinity. Based on these considerations, Site CA-RIV-8835 as a whole does not appear to meet the criteria for listing in the California Register of Historical Resources_ However, the cremated human remains identified at CA-RIV-8835 retain a high degree of traditional cultural value to the local Native American community. As such, the portion of the site containing the cremation remains does appear to meet the criteria for listing in the California Register. Report Citation : Eddy, John J., Mariam Dahdul, Harry M.

The crossing will be replaced with a four- span bridge 480 feet long and 86 feet wide. The bridge typical section consists of six-foot sidewalk on both sides of the bridge, two (2) eight-foot outside shoulders also serving as bike/golf cart lanes, a 10 foot raised median, two (2) eleven-foot travel lanes, and two (2) twelve-foot travel lanes (Figure Appendix D-1). The proposed configuration will be consistent with the existing four lane roadway section to the south, and the City’s current improvement project to the north (project number 2009-04), which will widen Dune Palms Road from two to four lanes with a median and left turn lanes. The proposed improvements will include a reconstruction of the north and south bridge approaches to accommodate the significant raised profile of the roadway. In order to match the roadway section on the south side of the bridge, the Project’s construction limits will be extended to 239 feet of Highway 111. On the north side of the bridge, the Project construction limits will be extended to include a vacant lot immediately north of the Project limits. The vacant lot is owned by the City and will be offered by the City in the bidding documents to be used for storage and construction staging by the contractor for the construction of this Project A more detailed project description is in the ASR (Gust et al 2016). The potential for subsurface archaeological material from the prehistoric period was identified in the Project APE. During the archaeological survey for the Project, prehistoric archaeological site P33-16950 was identified in the APE east of Dune Palms Road and north of Hwy 111 (APN 600- 030-018). The site occupies most of the parcel and extends into the construction limits or Area of Direct Impact (ADI) along Dune Palms Road (see Site Map in Section 10.0). The portion of the site outside the ADI was tested using shovel test pits (STPs), hand-excavated units, and backhoe trenches in 2008 (Eddy et al. 2008) and subsurface archaeological material and human remains were found. Additional units were excavated to recover all of the human remains. As a result of the survey for the current project (Gust et al 2016), ceramic sherds and daub, along with one flake (debitage), were identified near Dune Palms Road and the P33-16950 site boundary was extended into the ADI. The part of the site in the ADI appeared greatly disturbed during the 2016 survey. No subsurface testing has been conducted in the portion of the site in the ADI. An Extended Phase I subsurface investigation is needed to determine whether subsurface prehistoric archaeological deposits extend horizontally into the ADI and if so, whether they can be protected by an ESA. If subsurface deposits are present, the Extended Phase I subsurface investigation will also determine whether the deposits are intact or too disturbed to contribute to the eligibility of site P33-16950. The Extended Phase I program will help determine the boundaries of the site as required by 36 CFR 800.4(b). Extended Phase I Proposal 2 Dune Palms Road Low Water Crossing Replacement Project July 2017 2.0 SITE CONTEXT The prehistoric and ethnographic context for the project area is provided in the ASR (Gust, et al 2016). Site P33-16950 was previously tested using shovel test pits (STPs), hand-excavated units, and backhoe trenches in 2008 (Eddy et al. 2008). Seven hundred and fourteen artifacts (prehistoric ceramic sherds, daub/FAC, ground stone fragments, and rocks) were recovered during surface collection prior to testing. Seven hundred and twelve artifacts consisting of ceramic sherds, marine and freshwater shell, ground stone, charcoal, faunal bone and human remains were recovered from the units. Additionally, 27 1 meter by 1 meter recovery units (RUs) were hand excavated around the location of the human remains and an additional 1,125 artifacts and ecofacts were found. The depth of the RUs ranged from 20 to 40 centimeters (cm) below surface. The report did not report which artifacts were identified at what depth, but the catalog indicates that a majority of the artifacts are in the upper 40 cm of the site. Sixteen items were found between 100 cm and 250 cm in depth. These items included 6 pieces of fire- affected rock, 1 piece of unburned sandy clay, 5 pieces of unburned clay, 1 faunal bone fragment, and 3 pieces of charcoal (Gust, et al 2016). Based on the testing program, Eddy et al. (2008) concluded that the site in general had “very limited ability to provide important new information for the study of prehistory in the Whitewater River Delta/ Dune Complex and surrounding region, [and] in light of the low quantity of formal artifacts it yielded… the site as a whole does not appear to qualify as a ‘historical resource’." In other words, they believed that based on the artifacts recovered, the site is not eligible for the CRHR. However, the cremated human remains retain a high degree of Native American traditional cultural value, so it was concluded that the portion of the site containing the cremated remains was eligible for the CRHR under CEQA. P33-16950 has not been evaluated for the NRHP. Ceramics and cremations indicate that site P33-16950 was occupied during the Peninsular Pattern of the Palomar Tradition (900 to 150 B.P.). Sites similar to P33-16950 occupied during the Peninsular Pattern appear to be resource procurement camps for people from nearby villages. The procured resources were likely taken back to the village for consumption or storage. Data from such sites could be used to address research issues about the kinds of resources procured (based on faunal bone, shell, and macrobotanical remains from flotation samples) and the activities that took place at these sites (based on functional artifact types and features). Issues of chronology and trade and exchange could also possibly be addressed. A more specific period of use for the site could be determined if charcoal for radiocarbon dating is present. Items traded in from outside the area could include marine shell beads from the coast and obsidian from the Coso source or the Obsidian Butte source. 3.0 SCOPE OF WORK Shovel test pits (STPs) will be excavated in the ADI along the east side of Dune Palms Road south of the stormwater channel (CVSC), as shown on the Site Map and Site Detail Map in Section 10.0. This is the area between the edge of Dune Palms Road and the ADI boundary to the east. The northern part of this area is where the recently extended P33-16950 site boundary (based on surface material) overlaps the ADI. Seventeen STPs systematically spaced 10 m apart will be excavated in this area with the STPs arranged in two north-south lines. STPs Extended Phase I Proposal 3 Dune Palms Road Low Water Crossing Replacement Project July 2017 will not be excavated to the north in the CVSC where there is a vertical drop of 10 to 18 feet. There is little or no potential for archaeological material in the channel (see Site Detail Map in Section 10.0). The STPs will be excavated by hand with shovels in arbitrary 20-centimeter (cm) levels and will be about 40 cm in diameter. Excavated material will be passed through 1/8th-inch mesh. Artifacts remaining in the screen will be placed in bags labeled with the appropriate provenience information. STPs will be excavated to a depth of 80 cm (it is not practical to excavate STPs beyond about 80 cm below surface). If subsurface artifacts are found in the lower levels of an STP, an auger will be used to assess whether cultural material continues below 80 cm. If subsurface prehistoric artifacts are found in STPs, a hand-excavated unit may be necessary to assess whether the artifacts are in a disturbed context. It is difficult to observe stratigraphy in the sides of STPs. However, a unit can provide information about stratigraphy (whether the archaeological material is mixed or in situ) by examining the unit sidewalls. If the unit is necessary, the unit will measure 1 m by 1 m and will be excavated by hand in arbitrary 10 cm levels. Excavated material will be passed through 1/8th-inch mesh. A profile of two perpendicular sidewalls will be drawn. Artifacts remaining in the screen will be placed in bags labeled with the appropriate provenience information. Artifacts will be identified, described, photographed, and drawn in ECORP’s lab in Redlands. A report will be prepared following the format required by Caltrans for an Extended Phase I investigation. The report will contain the project description, the methods used, and will describe the results, including any artifacts recovered. The report will contain a discussion of whether intact subsurface archaeological deposits are present. The Principal Investigator for the Extended Phase I Investigation will be Roger Mason who has a Ph.D. in Anthropology from the University of Texas, Austin. He has over 30 years of experience in southern California archaeological investigations. The Field Director will be Robert Cunningham who has a B.A. in Anthropology from UCLA and has 9 years of experience. 4.0 DECISION THRESHOLDS STPs will be excavated to the maximum practical depth for STPs (80 cm). However, if archaeological material is found in a 20 cm level of an STP and the deposits appear to be undisturbed, the remaining levels of the STP will not be excavated so as not to further disturb intact archaeological material. However, if it cannot be determined if the archaeological material is from a disturbed or undisturbed context, the remaining levels of the STP will be excavated. STPs will be considered sterile if they contain no archaeological material. If no archaeological material is found in any of the STPs, it will be concluded that there is not a substantial subsurface deposit in the ADI. If archaeological material is present in the STPs, the degree of disturbance will be assessed by examining the sediments and other material from the STPs. Recent intrusive material indicating disturbance could include road gravel, chunks of concrete or asphalt, and recent refuse (glass, metal, plastic). If such material is present, it will be concluded that the deposit is so disturbed that it would no longer have the potential to contribute to the eligibility of the site as a whole. If such material is not present, but the Extended Phase I Proposal 4 Dune Palms Road Low Water Crossing Replacement Project July 2017 sediments from the STPs appear disturbed, a unit will be excavated and the sidewall profiles will be examined. If there is variation by depth in the type (sand, silt, loam) and color of the sediments and it appears that sediments characteristic of the upper levels have been introduced into the lower levels, it will be concluded that the deposit is too disturbed to have the potential to contribute to the eligibility of the site as a whole. If archaeological material is found in the STPs in an undisturbed context, the Extended Phase I subsurface investigation will cease and units will be excavated as part of a Phase II program to evaluate whether the material can contribute to the eligibility of the site as a whole. The evaluation would take into account the results of the previous test program (Eddy et al. 2008), along with the material found in the Phase II units in the ADI. 5.0 TIMETABLE The fieldwork will require 6 days (if the unit is necessary) and will be scheduled upon acceptance of this Extended Phase I Proposal and upon notification by the City that property access has been obtained (see Section 8). Lab work (if material is found) will require two days and report preparation will require one week. However, the total calendar time for completion of the report may be extended to account for Native American coordination. 6.0 NATIVE AMERICAN COORDINATION Twenty Native American groups were contacted as part of the initial Native American coordination as part of the ASR preparation. The Agua Caliente Band of Mission Indians, the Augustine Band of Mission Indians, and the Morongo Band of Mission Indians all requested that a Native American monitor observe all project-related ground disturbing activities. The Torres- Martinez Desert Cahuilla Indians stated that an MLD from their group supervised the reburial of human remains from site P33-16950 in 2008, but they did not know where the remains were reburied. They consider the entire area from Washington to Jefferson Streets to be part of one large village. A letter providing updated information about the project was sent by the City of La Quinta to the following Native American contacts: Luther Salgado, Chairman, Cahuilla Band of Indians Ernest Siva, Tribal Elder, Morongo Band of Mission Indians Karen Kupcha, Augustine Band of Cahuilla Mission Indians Patricia Garcia, THPO, Agua Caliente Band of Cahuilla Indians Michael Mirelez, Cultural Resources Coordinator, Torres-Martinez Desert Cahuilla Indians William Vance, Tribal Vice Chairman of the Augustine Band of Cahuilla Mission Indians replied that the Band is unaware of specific cultural resources that may be affected by the proposed project. They recommended that a qualified Native American monitor be present during construction and they wish to be notified if any cultural resources are discovered. No other responses to the letter were received. Extended Phase I Proposal 5 Dune Palms Road Low Water Crossing Replacement Project July 2017 In telephone calls on May 3, 2017, Patricia Garcia, THPO, Agua Caliente Band of Cahuilla Indians and Michael Mirelez, Cultural Resources Coordinator, Torres-Martinez Desert Cahuilla Indians, stated that they wished to supply a Native American monitor to observe the Extended Phase I Program. An agreement for Native American monitoring was received from Agua Caliente, but not from Torres-Martinez. In a follow-up telephone call on June 20, Michael Mirelez of Torres-Martinez said that they could not find a qualified monitor and that they defer to Agua Caliente for Native American monitoring. As confirmed in a phone call with Patricia Garcia on June 20, a Native American monitor for the Extended Phase I Program will be supplied by the Agua Caliente Band. If human remains are discovered in a location other than a dedicated cemetery, the provisions and regulations of Health and Safety Code 7050.5, CEQA 15064.5(e), and Public Resources Code 5097.98 will be followed; archaeological excavation will cease and the Field Director will notify the ECORP Project Archaeologist who will notify the Caltrans Archaeologist, Caltrans District 8 Native American Coordinator, and the Riverside County Coroner. The Field Director will maintain control of the area until the Coroner arrives. If the Coroner determines the remains are Native American and not the result of a crime, then the Coroner will notify the NAHC, which then will designate a Native American Most Likely Descendant (MLD) for the project. When the MLD visits the site, the Field Director will be present. The designated MLD will have 48 hours from the time access to the property is granted to make recommendations concerning treatment of the remains. The MLD’s recommendations will be given to the landowner and Caltrans. 7.0 CURATION Recovered archaeological material will be temporarily maintained at the ECORP office in Redlands until a curation agreement with an acceptable facility is obtained. The curation agreement and a collection agreement with the property owner will be in place by the time the XPI field work begins. All prehistoric artifacts will be curated. 8.0 ARCHAEOLOGICAL PERMITS Permission from the owner of the property at APN 600-030-018 will be necessary in order to excavate the STPs. The City of La Quinta will obtain a Right to Enter access agreement with the landowner.

The City proposes to remove the existing low-water crossing of Dune Palms Road at the Coachella Valley Storm Water Channel and replace it with a four-span bridge. During an earlier archaeological survey as part of the Phase I study for the Project, one prehistoric archaeological site (P33-16950) was identified in the APE east of Dune Palms Road and north of Highway 111 (Hwy 111). Previous subsurface testing at the site identified buried archaeological deposits and human remains. In order to determine whether or not subsurface prehistoric archaeological deposits extend into the Area of Direct Impacts (ADI), an Extended Phase I study, including subsurface investigation was completed. Prior to the commencement of field work, a Right of Entry Permit was obtained from the property owner of the parcel by the City, and a curation agreement for the study was put in place with the Western Science Center in Hemet. Fieldwork for this study consisted of excavating 17 shovel test pits (STPs) to determine whether subsurface prehistoric archaeological deposits associated with P33-16950 extend into the ADI. Each STP was excavated by hand in 20-centimeter (cm) levels to a depth of 80 cm. All work was monitored by a Native American monitor supplied by the Agua Caliente Band of Cahuilla Indians. The results from the STPs indicate that an intact subsurface deposit of prehistoric material from site P33-16950 is not present in the upper 80 cm of soil within the Dune Palms Road Low Water Crossing ADI. All 17 STPs were sterile and did not contain any cultural material associated with site P33-16950. In addition, evidence of previous disturbance was noted in multiple STPs as evidenced by the presence of modern debris at depths exceeding 60 and 70 cm below the surface. Intact native sediments were noted in two STPs at a depth below 60 cm. However, no cultural materials were noted in these sediments. Based on these results, it does not appear that the subsurface deposits within P33-16950 extend into the ADI at the depths tested. The horizontal boundaries of the site remain as defined in 2008. ii TABLE OF CONTENTS SUMMARY OF FINDINGS ............................................................................................................I TABLE OF CONTENTS ..................................................................................................................

The crossing will be replaced with a four- span bridge 480 feet long and 86 feet wide. The bridge typical section consists of six-foot sidewalk on both sides of the bridge, two eight-foot outside shoulders also serving as bike/golf cart lanes, a 10-foot raised median, two 11-foot travel lanes, and two 12-foot travel lanes. The proposed configuration will be consistent with the existing four-lane roadway section to the south, and the City’s current improvement project to the north (project number 2009-04), which will widen Dune Palms Road from two to four lanes with a median and left turn lanes. The proposed improvements will include a reconstruction of the north and south bridge approaches to accommodate the significant raised profile of the roadway. In order to match the roadway section on the south side of the bridge, the Project’s construction limits will be extended to 239 feet north of Highway 111 (Hwy 111). On the north side of the bridge, the Project construction limits will be extended to include a vacant lot immediately north of the Project limits. The vacant lot is owned by the City and will be offered by the City in the bidding documents to be used for storage and construction staging by the contractor for the construction of this Project. A more detailed project description can be found in the ASR (Gust et al. 2016). During the archaeological survey for the Project, prehistoric archaeological site P33-16950 was identified in the APE east of Dune Palms Road and north of Hwy 111 (APN 600-030-018). The site occupies most of the parcel and extends into the construction limits or Area of Direct Impact (ADI) along Dune Palms Road. The portion of the site outside the ADI was tested using shovel test pits (STPs), hand-excavated units, and backhoe trenches in 2008 (Eddy et al. 2008) and subsurface archaeological material and human remains were found. Additional units were excavated to recover all of the human remains. As a result of the survey for the current Project (Gust et al. 2016), ceramic sherds and daub, along with one flake (debitage), were identified near Dune Palms Road and the P33-16950 site boundary defined in 2008 was extended into the ADI in 2016. The part of the site in the ADI appeared greatly disturbed during the 2016 survey. At the time the ASR was prepared, no subsurface testing had been conducted in the portion of the site in the ADI. An Extended Phase I subsurface investigation was carried out to determine whether subsurface prehistoric archaeological deposits are present in the ADI and if so, whether they can be protected by the establishment of an ESA. If subsurface deposits are present, the Extended Phase I subsurface investigation was also designed to determine whether the deposits are intact or too disturbed to contribute to the eligibility of site P33-16950. The Extended Phase I study will help determine the boundaries of the site as required by 36 CFR 800.4(b). 2 1.2 Fieldwork Fieldwork was conducted on July 17 to July 20, 2017. The Principal Investigator for this Extended Phase I project is Roger Mason who has a Ph.D. in Anthropology from the University of Texas, Austin. He has over 30 years of experience in southern California archaeological investigations. The Field Director is Robert Cunningham who has a B.A. in Anthropology from UCLA and has 9 years of experience. The field crew consisted of Andrew Myers and Matthew Willenborg. Mr. Myers has a B.A. in Sociology from UCSB and five years of experience in southern California archaeology. Mr. Willenborg has a B.A. from California State University, San Bernardino and has two years of experience in southern California archaeology. 1.3 Permits Prior to the commencement of fieldwork, a Right of Entry Permit for the property where P33- 16950 is located (APN 600-030-018) was obtained from the property owner of the parcel by the City of La Quinta for the dates of April 10 to June 30. This permit was extended, via email exchange, to include the dates of the fieldwork (Attachment A). 1.4 Curation Agreement A curation agreement for the study, dated July 10, 2017, was put in place with the Western Science Center in Hemet, Riverside County, California. In this agreement, the Western Science Center agreed to serve as the repository for artifacts collected as a part of the project (Attachment A). 1.5 Human Bone Disposition If human remains were discovered in a location other than a dedicated cemetery, the provisions and regulations of Health and Safety Code 7050.5, CEQA 15064.5(e), and Public Resources Code 5097.98 would be followed; archaeological excavation will cease and the Field Director will notify the ECORP Project Archaeologist who will notify the Caltrans Archaeologist, Caltrans District 8 Native American Coordinator, and the Riverside County Coroner. The Field Director will maintain control of the area until the Coroner arrives. If the Coroner determines the remains are Native American and not the result of a crime, then the Coroner will notify the NAHC, which then will designate a Native American Most Likely Descendant (MLD) for the project. When the MLD visits the site, the Field Director will be present. The designated MLD will have 48 hours from the time access to the property is granted to make recommendations concerning treatment of the remains. The MLD’s recommendations will be given to the landowner and Caltrans. 1.6 Native American Consultation and Monitoring Twenty Native American groups were contacted as part of the initial Native American coordination as part of the ASR preparation. The Agua Caliente Band of Mission Indians and the Morongo Band of Mission Indians requested that a Native American monitor observe all project- related ground disturbing activities. The Augustine Band of Mission Indians suggested that a Native American monitor be present. The Torres- Martinez Desert Cahuilla Indians stated that 3 an MLD from their group supervised the reburial of human remains from site P33-16950 in 2008, but they did not know where the remains were reburied. They consider the entire area from Washington to Jefferson Streets to be part of one large village. A letter providing updated information about the project was sent by the City of La Quinta to the following Native American contacts: Luther Salgado, Chairman, Cahuilla Band of Indians Ernest Siva, Tribal Elder, Morongo Band of Mission Indians Karen Kupcha, Augustine Band of Cahuilla Mission Indians Patricia Garcia, THPO, Agua Caliente Band of Cahuilla Indians Michael Mirelez, Cultural Resources Coordinator, Torres-Martinez Desert Cahuilla Indians William Vance, Tribal Vice Chairman of the Augustine Band of Cahuilla Mission Indians replied that the Band is unaware of specific cultural resources that may be affected by the proposed project. They recommended that a qualified Native American monitor be present during construction and they wish to be notified if any cultural resources are discovered. No other responses to the letter were received. The Agua Caliente Band of Mission Indians and the Torres-Martinez Desert Cahuilla Indians were asked if they wished to provide Native American monitors for the project. ECORP contacted Patricia Garcia-Plotkin, the Director of the Tribal Historic Preservation Office for the Agua Caliente Band of Mission Indians and Michael Mirelez, the Cultural Resources Coordinator, for the Torres-Martinez Desert Cahuilla Indians via telephone calls on May 31, 2017. Both Tribes initially expressed interest in providing monitors for the Project. Agua Caliente agreed to supply a Native American monitor on June 25, 2017. Mr. Mirelez of Torres-Martinez stated that the Tribe could not find a qualified monitor. Mr. Mirelez deferred to the Agua Caliente for Native American monitoring for the study. Native American monitors were supplied by the Agua Caliente Band for the entirety of the Extended Phase I fieldwork. 2.0 SITE CONTEXT The context for P33-16950 is provided in the Archaeological Survey Report (Gust et al. 2016) and the Extended Phase I Proposal (Mason 2017). 3.0 SCOPE OF WORK Fieldwork for this Project consisted of excavating shovel test pits (STPs) to determine whether subsurface prehistoric archaeological deposits associated with P33-16950 extend into the ADI. The Extended Phase I Proposal (Proposal) stipulated that STPs be excavated to the maximum practical depth for STPs (80 cm). However, if archaeological material was found in a 20-cm level of an STP and the deposits appeared to be undisturbed, the remaining levels of the STP would not be excavated. However, if it could be determined that the archaeological material was from a disturbed or undisturbed context, the remaining levels of the STP would be excavated. STPs would be considered sterile if they contained no archaeological material (Mason 2017). 4 A total of 17 shovel test pits (STPs) were excavated in the ADI (see Study Site Map in Section 7). Fourteen STPs, numbered 1 through 14, were excavated in two parallel north-south rows. The westernmost row ran parallel to Dune Palms Road and consisted of STPs numbered 1, 3, 5, 7, 10, 11, and 13. The second row of STPs was located approximately 10 meters (m) to the east and consisted of STPs numbered 2, 4, 6, 8, 9, 12, and 14. The remaining three STPs, numbered 15 through 17, extended in a line south from STP 14. All STPs were spaced approximately 10 m apart. The locations of two STPs were adjusted due to vegetation. STP 7 was moved approximately 1 m south of the proposed location due to a large bush, and STP 9 was moved approximately 50 cm south due to another large bush. Six STPs (STPs 1, 2, 3, 4, 6, and 8) were located within the P33-16590 boundary. Each STP was excavated by hand in 20-cm levels using a round-tip shovel and chisel-tip dig bar. The diameter of the STPs was about 40 cm. Each STP was excavated to a depth of 80 cm. Excavated sediments from the STPs were screened through 1/8-inch wire mesh. Notes about cultural material and soils were taken on ECORP STP forms. All STPs were backfilled immediately upon their completion and flagging and equipment were removed from the vicinity. In total, 64 person hours were expended for the archaeological staff in the field and 32 hours were expended for the Tribal Monitor. 4.0 STUDY RESULTS One ceramic sherd was observed on the surface within the 2016 site boundary in the ADI, but no cultural material was identified within the 17 STPs excavated. The field crew noted charcoal within STP 6 at a depth of 40 cm. However, modern plastic was also noted at the same depth within STP 6, and there was no evidence that the charcoal was cultural or prehistoric in origin. Unmodified shell fragments were also noted in disturbed contexts (associated with modern debris) in STP 7 at a depth of 60 to 70 cm and in STP 12 in undisturbed contexts. The shell fragments appeared to be from bivalves, but were 1 cm or less in size and did not include hinges or other readily identifiable markers. Surface sediments within the Project ADI consist of Holocene alluvial valley sand and clay deposits and Holocene fluvial sand and gravel from the Whitewater River (Dibblee, Jr. and Minch 2008). Soils consist of Myoma fine sand with 5- to 15-percent slopes in the flat area south of the Whitewater River channel and Coachella fine sand with 0- to 2-percent slopes in and adjacent to the Whitewater channel (Soilweb 2017). Observations from the STPs indicated that the sediments within the ADI consist of silty sand containing small angular gravel clasts. Modern debris, including glass fragments, plastic, and concrete was noted down to a depth at or exceeding 60 cm in 14 of the 17 STPs. Given the proximity of the ADI to Dune Palms Road and the Whitewater Channel, the top 60 cm of sediment within the ADI appears to represent overburden from road construction or periodic cleaning of the Whitewater River channel. In STPs 3 and 12 archaeologists noted more compact, clay-rich sediments below a depth of 60 cm below surface (cmbs). This clay-rich stratum lacked the modern debris seen in the sediments above 60 cm in these STPs. Unmodified shell fragments were noted in these deeper sediments within STP 12. This deeper stratum may represent undisturbed possibly native sediments. However, no cultural material was found in these sediments. 5 The Extended Phase I study showed that subsurface prehistoric archaeological deposits associated with P33-16950 are not present in the ADI. There appears to be no intact subsurface material from site P33-16950 in the ADI. Although cultural material was found on the surface which caused the site boundary to be extended into the ADI in 2016, as shown on the Study Site Map, this surface material appears to represent a modern and secondary deposition of cultural material. The updated DPR 523 record is in Attachment B. Photos are in Attachment C. 5.0 SUMMARY AND CONCLUSIONS The results from the STPs show that an intact subsurface deposit of prehistoric material from site P33-16950 is not present in the upper 80 cm of soil within the Dune Palms Road Low Water Crossing ADI. No cultural material associated with site P33-16950 was found in any of the 17 STPs. In addition, evidence of previous disturbance was noted in multiple STPs as evidenced by the presence of modern debris at depths exceeding 60 and 70 cm below the surface. Intact native sediments were noted in two STPs at a depth below 60 cm, but no cultural material was noted in these sediments. Based on these results, it does not appear that the subsurface deposits within P33-16950 extend into the ADI at the depths tested. The cultural material seen on the surface in the ADI in 2016 is part of a modern secondary deposition of cultural material. Therefore, the site boundary remains as defined in 2008 and does not extend into the ADI. These conclusions are based on the tested sample with STPs spaced 10 m apart and excavated to a depth of 80 cm. It is Caltrans’ policy to avoid cultural resources whenever possible. If buried cultural materials are encountered during construction, it is Caltrans’ policy that work stop in that area until a qualified archaeologist can evaluate the nature and significance of the find. Additional survey will be required if the Project changes to include areas not previously surveyed. 6 6.0 REFERENCES CITED Dibblee, Jr., Thomas and John A.

Description: (Describe resource and its major elements. Include design, materials, condition, alterations, size, setting, and boundaries) This site was originally recorded by CRM Tech in 2008. They describe the site as containing a light scatter of burned clay, fire- affected rock, and pottery. Subsurface testing at the site was conducted by CRM Tech in 2008 using shovel test pits (STPs), hand- excavated units, and backhoe trenches. Subsurface archaeological material and human remains were found. In 2016, an updated survey by Cogstone identified additional ceramic sherds and daub along with one flake (debitage) to the northwest of the P33- 16950 site boundary. As a result, the site boundary was was extended northwest toward Dune Palms Road . In 2017, the City of La Quinta proposed to remove a the low water crossing along Dune Palms Road at the Whitewater river channel. The proposed area of direct impacts (ADI) overlapped the site boundary extension noted by Cogstone in 2016. Because this portion of the site had not been tested previously, an Extended Phase I subsurface investigation was completed to determine whether subsurface prehistoric archaeological deposits extend horizontally into the ADI (see continuation sheet). *P3b.

Description (continued): In July 2017, ECORP consulting, Inc. excavated 17 STPs near Dune Palms Road within the 2016 extension of the site. No cultural material was identified within any of the 17 STPs excavated. The field crew noted charcoal within STP 6 at a depth of 40 centimeters below surface (cmbs). However, modern plastic was also noted at the same depth within STP 6 and there was no evidence that the charcoal was cultural or prehistoric in origin. Unmodified shell fragments were also noted in disturbed contexts (associated with modern debris) in STP 7 at a depth of 60 to 70 cmbs. The results from the STPs suggest that an intact subsurface deposit of prehistoric material from site P33-16950 is not present in the upper 80 cm of soil within the northwestern extension of P33-16950. In addition, evidence of previous disturbance was indicated by the presence of modern debris at depths exceeding 60 and 70 cmbs in 14 of the 17 STPs. Intact native sediments were noted in two STPs at a depth below 60 cmbs. No cultural materials were noted in these sediments. The results of the STPs showed that the material on the surface near the road is part of a modern secondary deposit. Therefore the site boundary reverts to the original site boundary defined in 2008 (see Sketch Map).

The improvements would provide safe access across the channel during all weather events, provide reliable routes for emergency vehicles, motorist, pedestrains and bicyclists and achieve the City’s General Plan goals for the corridor. The bridge is funded by the federal Highway Bridge Project (HBP) program. Caltrans District 8, on behalf of FHWA, is the federal lead agency for this project. The project requires compliance with the January 2014 First Amended Programmatic Agreement Among the Federal Highway Administration, the Advisory Council on Historic Preservation, the California State Historic Preservation Officer, and the California Department of Transportation Regarding Compliance with Section 106 of the National Historic Preservation Act, as it pertains to the Administration of the Federal-Aid Highway Program in California (PA). The record search at the Eastern Information Center determined that no built environment resources had previously been recorded within the Area of Potential Effects (APE). The APE was surveyed by a qualified architectural historian and only the Dune Palms Mobile Estates Park located within APN 600-030-010 was determined to have constituents older than 45 years and would therefore require evaluation. The buildings on this parcel were identified, recorded, and evaluated per National Register of Historic Places (NRHP) and California Register of Historic Resources (CRHR) eligibility criteria to determine if they qualified for listing for either register. The mobile home park was evaluated as a historic district. There were no other buildings or structures within the APE but outside the boundary of the mobile home park that are more than 45 years of age or older that would require individual evaluation for historic significance. The mobile home park does not appear eligible for listing on the NRHP or on the CRHR as a historic district, nor do any individual resources within appear eligible for either listing individually. The results of the survey of the project APE for built environment resources determined that there are no historic properties present within the APE for the purposes of Section 106 of the National Historic Preservation Act (NHPA) or any historical resources for the purposes of the California Environmental Quality Act (CEQA).

The improvements would provide safe access across the channel during all weather events, provide reliable routes for emergency vehicles, motorist, pedestrains and bicyclists and achieve the City’s General Plan goals for the corridor. The Project is located immediately north of State Route 111 and south of Westward Ho Drive in the City of La Quinta, western Riverside County, California (Appendix B, Map 2). Located entirely within the city limits of La Quinta, the Project is depicted on the La Quinta 7.5 minute USGS quadrangle in Sections 20 and 29; Township 5 South, Range 7 East, San Bernardino Baseline and Meridian. The existing roadway crosses the CVSC at the channel grade. The roadway width is 68 feet at the crossing, and consists of one northbound and two southbound through lanes, an eight foot wide walkway area along the western edge, and an eight-foot wide shoulder along the eastern edge of the road, and no median. The existing roadway approach south of the crossing consists of one northbound and two southbound through lanes. The northern roadway approach consists of one through lane in each direction. The transition from one to two lanes in the southbound direction occurs at the midpoint of the channel crossing. Dune Palms Road becomes a four lane roadway with a median approximately one-quarter mile north of the channel low-water crossing and just south of the project limits. The roadway section just north of the crossing will be widened as part of an approved City project. The project was originally approved with a Mitigated Negative Declaration under CEQA in April 2010. The Project proposes to remove the existing low-water crossing on Dune Palms Road at the CVSC in the City of La Quinta, Riverside County. The crossing would be replaced with a 480- foot long and 86-foot wide three-span bridge. The bridge typical section consists of a six-foot sidewalk on both sides of the bridge, two (2) 8-foot outside shoulders also serving as bike/golf cart lanes, a 10-foot raised median, two (2) 11-foot travel lanes, and two (2) 12-foot travel lanes. The proposed configuration will be consistent with the existing four lane roadway section to the south, and the City’s current improvement project to the north (project number 2009-04), which will widen Dune Palms Road from two to four lanes with a median and left turn lanes. The proposed improvements would include reconstruction of the north and south bridge approaches to accommodate the significant raised profile of the roadway. In order to match the roadway section on the south side of the bridge, the project’s construction limits will be extended to within 239 feet of Highway 111. On the north side of the bridge, the project construction Dune Palms Low Water Bridge Replacement HRER 2 limits would be extended to include a vacant lot immediately north of the project limits. The vacant lot is owned by the City and would be offered by the City in the bidding documents to be used for storage and construction staging by the contractor for the construction of this project. As a part of the bridge construction, concrete slope protection would be installed along the north side of the channel. Additionally, minor removal and replacement of slope protection would be required on the south side of the channel west of the proposed bridge and extension of slope protection approximately 300 feet downstream of the proposed bridge. The slope protection is needed for scour countermeasures. As a result of the proposed cast-in-place drilled shaft bridge construction, scour protection within the bottom of the channel should not be required. As a result of the existing low water crossing acting as a quasi-grade control structure for the CVSC, sediment has been deposited on the upstream side of the channel from Dune Palms Road since the original construction. Additionally, on the downstream side of the Dune Palms Road crossing, the channel has an area of scour. Therefore the elevation differential between the upstream and downstream channel bottom is approximately eleven (11) feet; therefore the project will grade the bottom of the channel 300 feet up and down stream of the crossing to provide a uniform channel bottom slope within the project area. The project will also include the following additional improvements: • Railing Architectural treatment. The bridge design will incorporate railing architectural treatment as required by the City’s standard design. • Integration of a regional Bike/Pedestrian/NEV corridor (CV Link). The Coachella Valley Association of Governments (CVAG) and the communities within the Coachella Valley are working together on the implementation of a regional Bike/Pedestrian/NEV corridor (CV Link) along Whitewater River and Coachella Valley Storm Water Channel. The project design will be consistent with these plans by allowing for the integration of a trail under crossing within the southern slope protection, which also includes a trail connector to the pedestrian and bike facilities proposed along Dune Palms Road in the project area. • Utility Relocation. The project will also require utility relocations for overhead electrical distribution lines (Imperial Irrigation District facility), adjustment to both water valve can and lids and the manhole covers, minor 12-inch ductile iron pipe water main relocations at each bridge abutment, and relocation of both a 12-inch and 18-inch sewer line at the northern bridge abutment. Both the water main and sewer line relocations would be minor in nature, with the relocation limited to the existing road right and or channel of way. The relocation of the overhead electrical lines is considered by IID as a minor relocation, due to a parallel underground system along the west side of Dune Palms Road. The project will Dune Palms Low Water Bridge Replacement HRER 3 coordinate with IID on providing the missing underground link crossing the channel through the placement of conduit on the proposed bridge. The placement of the electrical system on the bridge will mostly likely allow IID to eliminate the overhead distribution facility along the east side of the road. For the water main, the relocation is also considered minor by CVWD standards. The two possible solutions for relocation would be either minor realignment work at the two abutments to eliminate any possible conflicts with abutment construction or relocation of the full length crossing the channel onto the bridge. The Project would require right-of-way acquisition from three parcels within the APE, located inthe northeast, southwest and southeast corners of the proposed bridge (APN’s 600-030-010, 600-390-021 and 600-030-018 respectively). APN’s 600-030-010 and 600-030-018 will require both street right of way acquisition as well as a temporary construction easement, and APN 600- 390-021 will require only a temporary construction easement. Note, the Project will not require any additional street right of way or construction easements from the High School property (APN 600-010-004) located at the northwest corner of the project area. The existing development at the northeast corner of the proposed bridge consists of a Mobile Home Park with one single family home, which is the park manager’s residence and, though outside the park fence, is part of the park (APN 600-030-010). Some of the mobile homes adjacent to the Dune Palms Road are encroaching within the street right of way. The project may require the acquisition of the single-family home site and relocation of two mobile homes. The existing roadway will be modified to construct a temporary bypass road. The temporary bypass will allow for staged construction of the bridge, and maintaining vehicle and pedestrian access at all times. Temporary and short term access impacts may occur during construction, and will require coordination with property owners, the public, and other stakeholders. Dune Palms Low Water Bridge Replacement HRER 4 AREA OF POTENTIAL EFFECTS The Area of Potential Effects (APE) includes both horizontal and vertical limits (Appendix B, Maps 3 and 5). The horizontal limits of the APE north of the CVSC are along the existing street right-of-way, along the west side of Dune Palms Road and include the entire intersection of Westward Ho Drive/Blackhawk Way and Dune Palms Road. The eastern extent of the APE north of the CVSC includes the intersection of Westward Ho Drive/Blackhawk Way and Dune Palms Road and continues east approximately 500 feet to encompass the city-owned Accessor’s Parcel Numbers (APNs) 600-030-020, 600-030-004, and 600-030-021 as well as privately- owned APNs 600-030-019 and 600-030-010. The 35,000 square foot staging area is located within APNs 600-030-021 and 600-030-004. The Dune Palms Mobile Estates mobile home park is located within APN 600-030-010. South of the Dune Palms Mobile Estates, the APE includes an approximately 750 foot wide section of the CVSC; this includes approximately 450 feet east of Dune Palms Road and approximately 300 feet west of Dune Palms Road. South of the CVSC, the western limit includes all of APN 600-390-021 as well as portions of the La Quinta Corporate Center (APNs 600-390-023 and 600-390-010). The eastern extent of the APE south of the CVSC includes the entire APN 600-030-018. The typical maximum vertical depth APE outside of the channel area would be 1 foot of excavation in undisturbed areas and up to 4 feet of excavation within the existing roadway street section, notwithstanding the above noted roadway approach fill areas. The maximum vertical depth APE for the portion of the project within the channel area is up to 80 feet of excavation for the bridge piers and up to 40 feet of excavation along the channel banks for the installation of the concrete slope protection. The construction of bridge piers would be accomplished by a large diameter (8 foot) auger. The APE totals 48.5 acres. RESEARCH METHODS Cogstone staff conducted a search for archaeological and historical records at the Eastern Information Center (EIC) for a one-mile radius around the APE on October 29, 2014. During the records search, the following sources were consulted: • California Historical Resources Inventory System (CHRIS) • National Register of Historic Places (NRHP) • California Historical Landmarks (CHL) • California Historical Resources Inventory (HRI) • California Points of Interest (PHI) • California Register of Historical Resources (CRHR) Dune Palms Low Water Bridge Replacement HRER 5 Online resources consulted include the City of La Quinta Historic Resources Inventory Database (HRID), historic topographic maps and historic aerial maps. Published and online references were consulted to develop a history of the APE vicinity. The record search did not locate any recorded built environmental structures within the APE. Within the one-mile search area, one historic structure was previously recorded, located outside the APE. Site P-33-4756 (CA-RIV-4756/H) is a historic-age concrete water valve tower with associated pipes and a fence along Adams Street. It was recommended as not eligible for NRHP listing by the surveyors. See the Archaeological Survey Report (ASR) for more details. In-person visits were made to the City of La Quinta Building Department and to the County of Riverside Building Department and Assessor’s Office on August 6, 2015 and on March 3, 2016. Cogstone staff also visited the Dune Palms Mobile Home Park on two separate occasions to conduct a survey and interview the Park Manager for information about the Park. Themes that are relevant to this Project include “Desert Recreation” and “Trailer and Mobile Home Parks” as they relate to the post-World War II years, from 1945 to 1975 in the Southern California desert. The two themes are interconnected and are treated as one here because trailer parks first came into existence in the region through recreational and travel activities. FIELD METHODS A field survey was performed on August 6, 2015, by Architectural Historian Lynn Furnis, M.A. The survey consisted of a pedestrian-level investigation of the historic built-environment resources located in the APE. Fieldwork included examining the style, construction, and materials of the built-environment resources, and recording and photographing those resources, which were mostly located in the south half of the park, since most of the mobile homes in the north half were known to have been moved to the park sometime after 1972 and, therefore, would be less than 45 years old. The row of mobile homes in the north half that border Dune Palms Road are the exception and they were recorded. They stand along a row that had been occupied by mobile homes prior to 1972 and some are old enough to have been there since that time. The data collected was then used to prepare the California Department of Parks and Recreation (DPR) 523 series site forms. Dune Palms Low Water Bridge Replacement HRER 6 HISTORICAL OVERVIEW The City of La Quinta began as a “watering hole” for gold miners traveling through the Coachella Valley on their way to Arizona. In 1862, Major William Bradshaw transported miners through the Valley and stopped at Point Happy (corner of Washington Street and Highway 111) which soon became a way station for stagecoaches and freight wagons traveling the Bradshaw trail (Soltys 2005:175). In 1876, the Southern Pacific Railroad (SPRR) constructed tracks through the region that today parallel US 86; they are now Union Pacific Railroad (UPRR) tracks and are located 9 miles east of the Project Area. The coming of the railroad spurred a new local industry. In the 1880s, enterprising growers in Coachella Valley imported date palms from the Middle East in an effort to produce dates for the American market (Miller 2012). The center of this effort was at nearby Indio and the effort was extremely successful. Coachella Valley’s dates comprise approximately 95 per cent of all dates consumed in the United States. The date palms provided a strong agricultural industry in the valley, with their fruit dependent on the local railroad for shipping to distant markets. The proliferation of date production was responsible for the founding of several Middle East inspired towns, such as Indio, Mecca, Oasis, and the now defunct Arabia and Edom (Miller 2012). The historical settlement pattern is reflected in land patents granted by the Government Land Office, which show that the Southern Pacific Railroad Company was granted patents in 1866 and the State of California in 1927 (BLM n.d.). In 1926, Walter Morgan founded the La Quinta Resort which attracted Hollywood celebrities and established La Quinta as a resort destination for Los Angeles’ wealthy population. The City of La Quinta, named for the Resort, was incorporated in 1982 and maintains a seasonal population and reputation as a premier resort town (City of La Quinta 2014). The 1904 USGS topographic quadrangle, the earliest available, shows no development or any other features near the APE with the exception of the Whitewater River. Highway 111 and Dune Palms Road are first depicted on the 1941 Toro Peak USGS 15 min. quadrangle. According to one article, there were more than 32 trailer parks in the Coachella Valley in the 1950s (Brown 2014). At this time, after World War II, people sought inexpensive recreation, often bringing their travel trailer with them to desert, beach, and mountain destinations. The many trailer parks around Palm Springs offered those seeking fall and winter sun and warmth, safe and familiar facilities, to which many of them returned year after year. Each park served as a small community, many of them having their own stores, restaurants, and recreational facilities such as heated pools and shuffleboards. The Dune Palms Mobile Home Park (parcel 600-030-010), as it was first called, was established in 1949, or shortly before (The Desert Sun 1949:13). A classified advertisement from December Dune Palms Low Water Bridge Replacement HRER 7 16, 1949 reads, under “Trailer Space” “DUNE PALMS Trailer Park, new, quiet, beautiful view of desert and mountains. Restful grass patio. On Dune Palms Rd, just off Highway 111, ½ mile west of Sun Gold Date Gardens. Reasonable rates” (The Desert Sun 1949:9). This park was probably always a more simple, plain, basic type of trailer park, as it remains today. According to the present park manager, the park was established in 1951 and at one time had a pond on the property (Michael Moss, March 3, 2016, personal communication). The 1972 aerial photograph shows the pond, located in the northeast quadrant of the park (NETR 1972). The 1972 aerial photograph is also the first to depict the Dune Palms Trailer Park (NETR 1972); it also appears on the 1973 La Quinta USGS 7.5 min. quadrangle. Though the park had been established in 1949, and presumably accommodated primarily small travel trailers, by 1972, it was providing lots primarily for larger, more long-term single-wide mobile homes. These were located primarily in the south half of the park. Much of the north half was vacant in 1972. It is possible that that portion of the park was reserved for winter visitors in their travel trailers, with the remainder being rented to year-round occupants, suggesting a transitional strategy to keep up with changing trailer park/ mobile home park trends. There are several permanent buildings in the park, including a community center, laundry room, tiny office, as well as a swimming pool, as well as the single-family house located outside the park fence. The house is the residence for the park manager and likely has been since at least 1972. The standing buildings do not appear to have been constructed in 1949, but rather sometime between 1959 and 1972 (NETR 1972; USGS 1959). A few buildings and a short east-west road first appear in this area in the 1959 La Quinta USGS 7.5 min. quadrangle (Map 4). In the USGS topographic maps from the 1960s and 1970s, and in aerial photographs from the early 1970s, crops of some kind were being cultivated on a few parcels within 0.25 mile of the Project Area. Today, the park is called the Dune Palms Mobile Estates. No other signs of development were apparent within or around the APE until 1996. Later aerial photographs show the presence of La Quinta High School by1996, a USA Gasoline Station on the northwest corner of the intersection of Highway 111 and Dune Palms Road by 2002, and the La Quinta Corporate Centre by 2005. HISTORIC THEMES Themes that are relevant to this Project include “Desert Recreation” and “Trailer and Mobile Home Parks” as they relate to the post-World War II years, from 1945 to 1975 in the Southern California desert. The two themes are interconnected and are treated as one here because trailer parks first came into existence in the region through recreational and travel activities and interests of Americans. As noted above, there were more than 32 trailer parks in the Coachella Valley in the 1950s (Brown 2014). After World War II, people were seeking inexpensive recreation, and traveling with their trailers for cheap lodging in the desert was a popular way to Dune Palms Low Water Bridge Replacement HRER 8 do it. Based on trailer parks designated as such on the 1973 USGS topographic map (USGS 1973), there were at least 35 trailer parks in existence in 1973 within the La Quinta, Coachella, Indio, Palm Desert, Cathedral City, and Palm Springs communities. Several of these were quite large. Palm Springs was the most famous, early desert resort in the Coachella Valley, beginning in the 1930s. Its sunny, warm winter climate drew year-round and seasonal residents. By 1939, the permanent population was 5,336, with more than 8,000 in the winter (Bogert 2016). One of its earliest trailer parks was established in the 1930s, known as Ramon Trailer Park (Brown 2014). It is still operating, with 250 mobile homes (no longer trailers) on 20 acres. At about this same time, famous Hollywood actors and actresses discovered the place and truly put Palm Springs on the map as a desirable resort town. Tourists with their travel trailers came in droves before and after World War II. The popularity of Palm Springs spread to the region as a whole, with Desert Hot Springs, Cathedral City, Rancho Mirage, La Quinta and other nearby communities being created or, if already in existence, then expanding and prospering through tourism and recreation. Golf courses and swimming pools were everywhere. Hollywood celebrities were also attracted to La Quinta, the very upscale resort established by Walter Morgan in 1926 (City of La Quinta 2014). La Quinta had few trailer parks, with just two shown in 1973 (USGS 1973). One of those was the Dune Palms Trailer Park, the other, name unknown, was located approximately 0.25 mile to the south-southeast, south of the Whitewater River and on the south side of Hwy 111. It appears to have been even smaller than the Dune Palms Trailer Park. The Dune Palms Trailer Park was 14 acres in size, as it remains today. The unnamed park was approximately 8 acres in extent. In neighboring communities, the number of trailer parks varied in 1973, with 13 in Palm Springs, eight in Indio, six in Cathedral City, four in Palm Desert, two in Coachella (USGS 1973). The range of trailer park types varied considerably within the Coachella Valley, from small, less structured parks like the Dune Palms Trailer Park to large, well-groomed parks with amenities such as wide, paved streets, extensive landscaping, large club houses and other ancillary buildings, large trailer spaces, and multiple pools. Bing Crosby’s Blue Skies Village in Rancho Mirage was one of the latter type (Brown 2014). As mentioned above, each park served as a small community, many of them having their own stores, restaurants, and recreational facilities. In the early years of auto camping, private camps tended to arrange camp spaces in a row that was either parallel to or perpendicular to the adjacent highway (Fowler et al. 2016:4). The older topographic maps indicate that the first interation of the Dune Palms Mobile Home Estates consisted of a single road oriented perpendicular to Dune Palms Road. Presumably, the trailers were lined up along one or both sides of this road or lane. As time went on, Dune Palms Trailer Park (later Dune Palms Mobile Dune Palms Low Water Bridge Replacement HRER 9 Estates) offered a swimming pool, small laundry room, a community room of some type, a pond in its early years, paved lanes, and narrow trailer and mobile home spaces. There is a tiny manager’s office on the grounds today, as well as a manager’s residence just outside the fenced park area, but still within the same parcel of land. By the mid-1950s, trailers had become larger and more spacious inside (Fowler et al. 2016:9, 11). They became more like permanent houses and less like travel trailers. Their larger sizes and more limited mobility, as well as their popularity, led to changes in the configuration of the later trailer parks, soon to be mobile home parks. The lots became larger and often had individual concrete patios. Each also had its own utilities, such as water, electricity, sewer, and garbage service. The street patterns within the parks became less grid-like and more curvilinear. And they were furnished with communal recreation or meeting buildings, playgrounds, and swimming pools, in addition to laundry rooms and park offices. They were also well-defined through outer fencing and landscaping, as well as more extensive landscaping between lots. The Dune Palms Trailer Park has some of the later features and some of the earlier features, reflecting its existence and transition from 1949 to the present. It has expanded its streets, from the original one, then to two parallel streets that are perpendicular to the adjacent main road. By 1972, there were two loops formed around the two streets. But individual spaces remain quite narrow for the most part, with little landscaping between them. Many do have concrete patios. The park is a mix of double-wide and single-wide mobile homes, with a few small trailers and even campers on trucks. The park has communal amenities such as a swimming pool, park office, laundry room, and community center, but it definitely appears to cater mostly to working families and a few retirees, rather than to mostly retirees looking to the park for social activities and recreation. When compared with the full spectrum of trailer and mobile home park possibilities available in the area in the 1940s to the 1970s, the Dune Palms Trailer Park was a very modest one. It contained approximately 100 spaces within its 14 acres. There were smaller parks, as well as some that were much larger and more refined. DESCRIPTION OF CULTURAL RESOURCES Through this study, one historic resource has been newly-recorded and evaluated; the Dune Palms Trailer Park. The DPR is included in Appendix C. Table 1. Properties Surveyed Older Than 45 Years Street Address Assessor’s Parcel No. (APN) Date of Construction Description 46-400 M.E. Dune Palms Road 600-30-010 Pre-1972 Trailer/Mobile Home Park Dune Palms Low Water Bridge Replacement HRER 10 The current Dune Palms Mobile Estates mobile home park comprises 14 acres and includes five permanent buildings and structures (pool, laundry room, community center, park office, and manager’s residence), five mobile homes that are more than 45 years old and 94 that are less than 45 years old. Due to the nature of the property type and the concentration of buildings, structures and objects within a defined boundary that have a shared historic context, the mobile home park was evaluated as a singular resource (historic district) instead of evaluating each individual feature therein. It was determined to not meet the NRHP or CRHR criteria because it does not appear to be a trailer or mobile home park that has specifically influenced or led the national or regional trends in trailer park development or popularity over time; it is not known to be associated with a person or persons important in national or regional history, it possesses most of the character-defining features for a mobile home park from the 1920-1969 period (Fowler et al. 2016), yet is not a good example of one. In addition, it retains little of its integrity since very few of the existing trailers and mobile homes are 45 years old or older and are not contributing district elements. Figure 1 below provides an aerial view of the mobile home park depicting its boundaries. Dune Palms Low Water Bridge Replacement HRER 11 Figure 1. Aerial view of Dune Palms Mobile Home Park Dune Palms Low Water Bridge Replacement HRER 12 FINDINGS AND CONCLUSIONS FINDINGS One property was evaluated for historic signficance. It consists of a trailer/mobile home park over 45-years of age, evaluated as a historic district. Inside the park fence are mobile homes and trailers, as well as permanent buildings such as a tiny manager’s office, a community building, a laundry room, and a swimming pool (Figure 2). Outside the fence but on the same parcel is a single-family house serving as the park manager’s residence. Cogstone recorded and evaluated the mobile home park as a district in keeping with Caltrans’s guidelines that a district “possesses a significant concentration, linkage, or continuityof sites, buildings, structures, or objects united historically or aesthetically by plan or physical development” (Caltrans 2014:5). The Dune Palms Trailer Park (District) satisfies the district definition in that it possesses a concentration and continuity of buildings that are united historically by plan and physical development (Figure 1). It’s historic name of Dune Palms Trailer Park was utilized rather than the modern name. The Dune Palms Trailer Park District is 66 years old. It retains five permanent structures that also appear to be at least 45 years old. The vast majority (95 per cent) of the existing mobile homes within the Park are less than 45 years old and/or have been moved to the Park within the past 43 years. Only five mobile homes appear to be 45 years old or more. These and the five permanent buildings and structures, as well as roads, comprise the main structures that have been part of the Park since between 1960 and 1972. They are contributing elements to the district. Still, the Dune Palms Trailer Park does not appear eligible for listing on the NRHP or on the CRHR. Lynn Furnis, a qualified architectural historian who meets the Professionally Qualified Staff Standards in the Section 106 Programmatic Agreement (Section 106 PA) Attachment 1 as an Architectural Historian or above, has determined that the other properties present within the Indirect APE, including federally-owned resources, meet the criteria for Section 106 PA Attachment 4 (Properties Exempt from Evaluation) as property types 4 and 5. Andrea Galvin, a qualified principal architectural historian, has concurred.

Dune Palms Low Water Bridge Replacement HRER 15 CONCLUSIONS This HRER evaluated one property within the APE. The results of the survey of the project APE for built environment resources determined that the only non-exempt property, the Dune Palms Trailer Park, does not have the potential to be considered a historic property under the NHPA or under CEQA, either individually or as a historic district.

Turn right onto Washington Street and proceed 3.3 miles. Turn left onto Highway 111 and proceed 1.2 miles. Then turn left onto Dune Palms Road. The mobile home park (site) is located 0.38 mile to the north, on the east (right) side of the road. *P3a. Description: The site consists of a complete mobile home park, dating to at least 1949. At present, the park includes 103 mobile home spaces, of which 99 are occupied, 97 of them filled with mobile homes and two with travel trailers. In addition, the park includes four permanent structures – a laundry room, a community center building, a swimming pool, and a small office. A single-family 1960s style house is situated outside the mobile home park, but at the southwest corner of the same parcel occupied by the park. There are two entrances from Dune Palms Road – a north entrance and a south entrance – and these lead to paved lanes and loops along which the mobile homes and structures stand. As of 1972, most of the mobile homes were located in the south half of the park, with just eight units in the north half and approximately 30 in the south half. All of the permanent structures are located in the south half. Because the mobile homes in the north half (except for the original 8) had to have been moved to the park after 1972, they have been there for 43 years or less. Those 41 mobile homes are not recorded or evaluated here, since they have been in the park less than 45 years and are not considered historic in age, no matter how old each actual mobile home might be.

Historic Name: Dune Palms Trailer Park D2. Common Name: Dune Palms Mobile Estates *D3. Detailed Description: The district consists of a complete mobile home park, dating to 1949. At present, the park includes 103 mobile home spaces, of which 99 are occupied, 97 of them filled with mobile homes and two with travel trailers. In addition, the park includes four permanent structures – a laundry room, a community center building, a swimming pool, and a small office. A single-family 1960s style house is situated outside the mobile home park, but at the southwest corner of the same parcel occupied by the park. This house was constructed by 1972 and likely was associated with the park. Very possibly, the owners and occupants of the house were also the owners of the original mobile home park, as all are situated within the same single, large parcel (APN 600-030-010). Today, the park’s manager resides in the house (See attached Continuation Sheet for additional text).. *D4. Boundary Description: The district is confined to the parcel known as APN 600-030-010, which is defined by Dune Palms Road on the west, by the Coachella Valley Storm Water Channel on the south, by the east boundary of the APN on the east, beyond which is a subdivision of tract homes, and by the north boundary of the APN, which is delineated by a paved east-west lane that is part of the church complex to the north, located on APN 600-030-019. The district boundary is the same as the current Dune Palms Mobile Estates Park. *D5. Boundary Justification: In terms of characteristics that provide cohesion, the Dune Palms Trailer Park District is unmistakable as a cohesive unit, as it is uniformly contained within the parcel boundaries. The park has an infrastructure, with two east-west entrance lanes, one for the north half and one for the south half. Each lane leads to a loop and to other, short cross lanes (north-south). These define the spaces along which all mobile homes, trailers, and permanent buildings are organized. *D6. Significance: Theme: Recreation Area: Southern California Desert Period of Significance: 1949-1970 Applicable Criteria: N/A The Dune Palms Trailer Park District is more than 45 years old. It retains four permanent structures that also appear to be at least 45 years old. But the vast majority (95 per cent) of the existing mobile homes within the Park are less than 45 years old and/or have been moved to the Park within the past 43 years. Only five mobile homes appear to be 45 years old or more. These and the five permanent buildings and structures, as well as roads, comprise the main structures that have been part of the Park since between 1960 and 1972. The District does not appear to be associated with events that have made a significant contribution to the broad patterns of history, and is therefore not eligible for NRHP listing under CriteriaA/1. The resource does not appear to be associated with the lives of significant persons in the past and is therefore not eligible for NRHP listing under CriteriaB/2. The Park does not embody the distinctive characteristics of a type, period, or method of construction, or represent the work of a master, or that possesses high artistic values, or represent a significant or distinguishable entity whose components may lack individual distinction. It is not considered eligible for NRHP listing under Critera C/3. This resource is not an archaeological resource and therefore Criteria D/4 do not apply. The District retains its integrity of materials, design, and location, but has lost its integrity of design, workmanship, setting, feeling, and association. It is recommended as not eligible for NRHP listing because it does not appear to be significant under any of the four criteria. Additionally, an estimated 5 per cent of the mobile homes present, plus all four of the permanent structures from pre-1972, and existing roads are the only historic-age remnants of the District. The large majority of mobile homes present today are less than 45 years old or were definitely moved to the park less than 45 years ago. *D7.

Description (continued): The south half of the park has 48 mobile homes and two travel trailers. The majority of these are not 45 years old or more. Most appear to be from the 1970s and 1980s. The same is true for the eight mobile homes in the north half. All of the permanent structures, including the single family house just outside the park, were in place by 1972 and are recorded and evaluated as part of this site record. Only those mobile homes that appear to date to the 1960s or older are described and evaluated here. Mobile Home Park Office Building: Standing adjacent to a mobile home along the north flank of the south entrance, at Space 29, the small wood-framed office building is found. It is rectangular in plan, one story in height, and is east-facing. It is oriented north-south. The roof is a shed roof, of low pitch, sloping to the west. It has a very wide overhang and open eaves to the south, but more narrow overhang on the other three elevations. On the south side, a palm tree grows through a large hole in the wide overhang. The small structure is partially clad in T1-11 siding (south elevation) and in sheet metal or other particle board sheeting elsewhere. On its east (front) elevation, the office has an entry door. On its south elevation, a pair of small fixed windows with faux muntins is set. A cement walkway separates the office from mobile home #29, where presumably the park manager lives. Laundry Room: A small, one-story, rectangular structure serves as the laundry room for the mobile home park. It faces west and is oriented north-south. It is located four mobile home spaces east of Dune Palms Road and along the south flank of the east-west road that leads into the park from the south entrance. The structure is side-gabled, with a roof of very low pitch. It has a moderate overhang and open eaves. The structure is clad in stucco. The structure’s front (west) elevation has two entry doors – one at the north end and one at the center. The central door has a metal security door on the front. A small window of unknown type is located between the doors, high up on the wall. A band of three more windows, all blinded, are located in the south half of the elevation. The north elevation includes one large central, fixed window with wood trim and an attached metal utility box. The east elevation is fitted with a large fixed window near the west end, one small blinded and barred window to the south, set high up on the wall, then with a boarded-up doorway near the center, and at least three large windows of unknown type in the south half of the elevation. A tall dog-eared fence and gate obscure the remainder of this elevation from view. A cement sidewalk leads from the lane along east and west elevations of the structure. Community Center Structure: An oddly-shaped structure located at the east end of the east-west south entrance lane is assumed to be a community center or social hall for the park residents, though there are no signs to indicate this. The single-story structure is of concrete block. It has a complex plan. It faces west and is oriented northeast-southwest. It appears that the original building was a shallow V shape, that had a later rectangular bay added to the rear, which appears to contain two bathrooms. The roof of the main, original part is a low-pitch shed roof, with a wide front (west) overhang and open eaves, but no overhang elsewhere, though it does have a wide, wooden fascia on the sides and rear. The shed roof slopes to the east. The roof on the addition is flat, with a wide overhang and open eaves. The structure’s west (front) elevation has a central entry door, with a metal security door in front. From there, the elevation spreads out in two wings, one to the southwest and one to the northwest. Most of it is clad in wide T1-11 siding, but the walls extend beyond the main building on both ends, to form tall wings composed of concrete block. The south elevation includes this narrow wing extension, then a plain wall expanse with no fenestration. The east elevation, also of concrete block, includes a blinded, barred window in the south half, a concrete block chimney at the center, then the rectangular addition bay on the north half. The north elevation of the main building is of concrete block, with a blinded, barred window near its east end, then the added bay, which is shorter in height than the main structure. This bay has an entry door off-center, with a metal security door on its north elevation. The south elevation of the bay has a similar door at its west end, abutting the chimney of the main structure. On its east elevation, it has two barred, blinded or painted windows situated high up on the wall. A wooden board is affixed at the center, vertically, and it braces a wooden light pole. The windows are identical hopper types, one for each bathroom. Palm trees are planted in front and at the rear of the building. Swimming Pool: A large swimming pool graces the south entrance of the park, with entrance and exit lanes skirting the pool area. The pool is oblong in shape, with a wide concrete apron around it on all sides, and fitted with two sets of steps and metal hand rails. A stout metal bar and concrete wall fence encloses the pool complex. It is filled with clean water and is obviously still being used.

Description (continued): Single Family Residence: The house that stands within the same parcel as the Dune Palms Mobile Estates Park, but just outside the southwest corner of the park is a single-story, west-facing house, oriented north-south. It is roughly rectangular in plan and vernacular in style, with Ranch elements. It has an attached garage. The house is set back from Dune Palms Road approximately 30-35 ft and is adjacent to the Whitewater River bed, which is just to the south. The house is set on higher ground, above the street and the river bed. The roof of the house may be cross-gabled, but this is not certain as the garage is front-gabled, while the roof of the house is obscured by a short vertical wall extension, on the west elevation at least. The house roof may be flat or side-gabled and low in pitch. The garage roof is covered in composition shingles and has a moderate overhang with open eaves. The front of the house (west elevation) is characterized the two-car garage front at the north end, with two original wood, pull-up doors. Recessed an estimated four ft from the garage front elevation, the north half of the house front has a front porch with west- sloping shed roof element supported by three stout rectangular, stuccoed columns. The porch has a cement slab floor. The front entrydoor is set near the center of the house’s west elevation, with four large aluminum-frame windows across the front. Each window has a single center, fixed pane and two side panes that may be sliders. The house and garage are clad in stucco. The only other elevation that is visible from the street is the north elevation of the garage. It reveals a central aluminum slider. The side and rear yards are fenced with tall, dog-eared wood fence. The front yard is planted with several large trees, a grass lawn, and shrubs and smaller plants; the rear and side yards also appear to have mature trees and shrubs. A short, paved driveway (oriented east-west) leads from the street to the garage, with a parking space located at the front of the house. This house is the residence of the Dune Palms Mobile Estates park manager and is still associated with the park. Mobile Home #24: The mobile home in space #24 is a metal-clad single-wide with convex roof of low pitch and rectangular plan. It is west-facing and oriented north-south. The unit is set just a few feet north of the east-west lane from the south entrance and immediately west of a small connecting lane between north and south halves of the Park. The mobile home’s west (front) elevation includes a sliding glass entry door that is devoid of access steps and apparently is no longer used as the main entry. Near its south end, the unit has a medium-sized louvered window with three glass panes. A wooden door is located in the north half of the elevation, with wooden steps and handrails providing access. A second small window is further north. The entire length of the west elevation is covered by a metal porch roof supported by small metal posts and one wooden post. Beneath it is a concrete pad. The south elevation has a vertical upper half, with a central horizontal three-part window, consisting of two side fixed panes and a central 1/1 sash window, all in aluminum frame. Above the window, interrupting the vertical plane is a decorative metal projection consisting of a horizontal shelf above the window supported by side “wings” that narrow towards the vertical center of the elevation. At that point, the lower half of the elevation is curved and recessed, then vertical at the base. The unit has a plywood skirt on all elevations. The space is devoid of vegetation except for a few potted plants within the front patio area. A 3-ft tall picket fence encloses a portion of the space on the west and north, where a storage shed stands. Mobile Home #27: The mobile home in space #27 is a metal-clad single-wide (10-12 ft wide) with a flat, bi-level roof. It is and rectangular in plan. It is west-facing and oriented north-south. The unit is set approximately 10 ft north of the east-west lane from the south entrance. The mobile home’s west (front) elevation includes a single-width wooden panel door with nine lights in the upper half. Originally, a sliding glass entry door may have occupied this space as a door-width span adjacent to the existing door is now covered with non-matching siding, apparently covering an older opening. Wooden steps and handrail provide access to the door. Near its south end, the unit has a medium-sized louvered window with eight panes. A large, three-part window graces the center of the elevation, with two side sliders. In the north half, a second door is located, also with wooden steps and handrail. A small window is further north. The entire length of the west elevation is covered by a metal porch roof supported by small metal posts, by a length of metal pipe, and by one wooden dowel. Beneath it is a concrete pad. The roof projects approximately 18 inches above the south one-third of the roof for the northern two-thirds. The south elevation includes the projecting roof element, which is fitted with a window. The main elevation has a projecting, winged roof element covering the upper half, with a central horizontal three-part window, consisting of two side fixed panes and a central 6-pane, louvered window, all in aluminum frame. Below the window is a narrow, decorative shelf of metal, below which DPR 523L (1/95) *Required information State of California  The Resources Agency Primary # DEPARTMENT OF PARKS AND RECREATION HRI# CONTINUATION SHEET Trinomial Page 7 of 15 *Resource Name or # 46-400 M.E.

Description (continued): the lower half of the elevation is curved and recessed, then vertical at the base. The unit is skirted and the sparsely landscaped yard has low, wrought iron fencing in front of the unit and across a dirt driveway on the east side of the mobile home. A second, main driveway parallels the unit on its west, just beyond the patio area. Mobile Home #30: This unit is a 1960s vintage mobile home, a narrow single-wide (8 ft), with a rectangular addition added on to the west elevation, and a carport on the east. This home has a flat, metal roof. The south elevation is now the front of the mobile home, due to the addition, but originally the west elevation would have been the front. The unit is set back from the south entrance exit lane approximately 10 ft, and is behind a tall fence. The single-wide is clad in metal sheeting, while the addition appears to be wood or a particle board material. Its west elevation consists of a rounded metal overhang that extends down from the roof, with a recessed horizontal band within which a large central, fixed window is set. Beneath the window, the elevation projects slightly to the south. A wooden “awning” has been added above the window to shade the window. The awning is supported by two metal rods. At each side of the recessed window band, there are wrought iron decorative curvilinear pieces, an attribute common to 1960s mobile homes. The south elevation of the addition includes the front entryway, off-center, with a wood, paneled front door, accessed by steps and a raised deck. The west elevation of the mobile home includes a small aluminum slider near the south end of the single-wide and two aluminum sliders along the west elevation of the addition. The addition is composed of panels of wood or particle board. It is covered by a carport-like or patio roof, composed of metal with slim metal supports. The east elevation has a carport cover, of metal with metal supports projecting to the east. A single-car width paved driveway is along the east side of the single-wide, and under the carport. The rear and side yards are fenced with tall, wood, dog-eared fencing. Two mature palm trees grow in the yard. Mobile Home #40: The late 1960s vintage mobile home in Space 40 is a wide single-wide unit (at least 10 ft), facing northeast and oriented southeast- northwest. It is set at an angle to the private park lane and its front end is within a few feet of the lane. The unit has a flat roof that rises slightly above the rear two-thirds of the mobile home, then continues on as a flat roof to the rear. It is covered in sheet metal. The northeast elevation is clad in T1-11 siding, apparently replacement siding. A trim of three narrow horizontal boards covers the upper edges of the siding. The front entryway is set within the northwestern one-third of the elevation and is a sliding glass door that is accessed by means of a set of stairs and small stoop with wide wooden hand rail. To the southeast of the deck is a second door, a wood panel one, accessed by means of a separate set of steps, stoop, and wood handrail. A small vinyl slider is found southeast of this door, with a medium-sized one near the northwest end of the elevation. The central area is covered with a metal and wood patio roof, supported by two thin metal posts. The northwest elevation is also clad in T1-11 siding with a central, vinyl slider. The uppermost elevation segment is a metal strip that projects out horizontally from the roof edge and then narrows until it merges with the siding. The strip is approximately 12 inches wide. Its flaring shape mimmicks winged overhang roof element beneath it, that is of wood and T1-11 and forms a shade over the small slider. The window has wide wood trim, the horizontal parts of which extend beyond the vertical trim. Beneath the window is a wide, wood or metal strip attached to the foot of the winged overhang, forming an angled decorative (and perhaps structural) band across the front elevation. A concrete slab forms a patio floor beneath the patio roof on the northeast elevation. Two chain link segments of 3-ft height form a gate to the patio. Miscellaneous, non-matching metal fence segments enclose the patio and yard areas on either side of the gate. A second, taller chain link fence encloses the yard on the southwest flank of the mobile home. Tall palm trees grow adjacent to the yard. Mobile Home #41: The 1960s vintage mobile home in Space 41 is a single-wide unit (8-10 ft), facing south and oriented east-west. It is set at an angle to the private park lane and its east end is within 5 feet of the lane. The metal-clad unit has a low-pitch, convex roof clad in metal. The south (front) elevation has a main entry door of wood in the east half, with wood steps and handrail providing access. Aluminum-framed, narrow windows flank the door. A second door is located in the west half, with another window beyond that. The south elevation is fitted with a stout metal patio roof, supported by narrow metal posts, covering a concrete slab.

Detailed Description (Continued): There are two entrances from Dune Palms Road – a north entrance and a south entrance – each oriented east-west and these lead to paved lanes and loops along which the mobile homes and structures stand. As of 1972, most of the mobile homes in the park were located in its south half, with just eight units in the north half and approximately 30 in the south half. All of the permanent structures, all present by 1972, were and are located in the park’s south half. Because the mobile homes in the north half (except for the original eight) had to have been moved to the park after 1972, they have been there for 43 years or less. Those 41 mobile homes are not recorded or evaluated here, since they have been in the park less than 45 years and are not considered historic in age, no matter how old each actual mobile home might be. The south half of the park currently is filled with 48 mobile homes and two travel trailers. The majority of these are not 45 years old or more, based on their styles. Most appear to date from the 1970s and 1980s. The same is true for the eight mobile homes in the north half. All of the permanent structures, including the single family house just outside the park, were in place by 1972 and have been recorded and evaluated as part of this district site record. Only those five mobile homes that appear to date to the 1960s or older are described and evaluated here. In terms of characteristics that provide cohesion, the Dune Palms Trailer Park District is unmistakable as a cohesive unit, as it is uniformly contained within the parcel boundaries. Dune Palms Road defines it on the west, the Coachella Valley Storm Water Channel (CVSWC) defines it on the south, and parcel boundaries that abut other parcels with different uses define it on the east and north. The park has an infrastructure, with two east-west entrance lanes, one for the north half and one for the south half. Each lane leads to a loop and to other, short cross lanes (north-south). These define the spaces along which all mobile homes, trailers, and permanent buildings are organized. The mobile home spaces are organized in long east-west rows, for the most part, though there are short north-south rows along the west and east boundaries. The individual spaces within most of the east-west rows are oriented at diagonals, northwest-southeast. A few rows, however, have spaces that are all oriented north-south. The permanent structures within the park serve as community focal points and are permanent elements that lend additional stability, organization, and a sense of longevity to the District. These include the well-maintained swimming pool and fenced area around it adjacent to the south entrance, the small office building situated close to the south entrance, the laundry room also situated near the south entrance, but amongst a row of mobile homes, the community center located at the east end of the south entrance lane, and the central parking lot just west of the community center. The Dune Palms Trailer Park District is situated in the Colorado Desert, within the Coachella Valley, and now a part of the La Quinta incorporated community. As late as 1972, the land immediately surrounding the Park was either bare undeveloped ground or else was under cultivation, perhaps growing date palms (NETR 1972). A few houses also existed by then, located to the north and east in small groups of four or five houses. At that time, there were grand, open views of mountains to the north and west. At present, the area has been extensively developed and the Park is surrounded by tract homes on the east, by churches and small businesses on the north, and by a high school across Dune Palms Road and to the northwest. *D7.

The crossing will be replaced with a fourspan bridge 480 feet long and 86 feet wide. The APE Map for the Project is attached. The following prehistoric archaeological sites will be protected by the designation of Environmentally Sensitive Areas (ESAs): • P33-16950 The ESA boundary for site P33-16950 will follow the parcel boundary for APN 600-030- 018 which encompasses the site (see Attachment A). The following measures are required during each stage of the Project. Pre-construction: • The Project Engineer and Project Archaeologist will ensure that the boundaries of the ESA are clearly described and illustrated in the Plans, Specifications, and Estimates (PS&E) package. • A pre-construction meeting with the Construction Supervisor and construction personnel will be held to discuss the ESAs, including access restrictions and maintenance of fencing for protective measures. • The Project Engineer will notify the Project Archaeologist at least three weeks prior to start of construction to allow for a field review of ESA locations and arrangements for monitoring of fence installation. • Review ESA locations in the field one week prior to start of construction. During construction: • Install temporary orange plastic fencing along ESA boundary at least one week prior to initiating construction, under the supervision of the Project Engineer and the Project Archaeologist. • Conduct monitoring of ground-disturbing activities in the ADI south of the Stormwater Channel by an archaeologist and a monitor approved by the Agua Caliente Band of Cahuilla Indians • Conduct spot monitoring and photo-documentation at various times throughout Project construction to ensure the integrity of the ESAs. ESA Action Plan 2 Dune Palms Road October 2017 Post-construction: • The Construction Supervisor will notify the Project Archaeologist when construction is complete in the vicinity of each site, so that the temporary fencing can be removed. • The Project Archaeologist will oversee the removal of the fencing by the construction personnel. Responsible parties are the Project Engineer, Construction Supervisor, Caltrans Archaeologist, and Project Archaeologist (consultant), Co-Principal Investigator (Co-PI) (Archaeologist) (consultant). 2.0 PROJECT DESCRIPTION The Dune Palms Road Low Water Crossing Replacement Project (Project) in the City of La Quinta (see Study Vicinity Map and Study Location Map in Section 7) proposes to remove the existing low-water crossing of Dune Palms Road at the Coachella Valley Storm Water Channel (CVSC) in the City of La Quinta, Riverside County. The crossing will be replaced with a fourspan bridge 480 feet long and 86 feet wide. The bridge typical section consists of six-foot sidewalk on both sides of the bridge, two eight-foot outside shoulders also serving as bike/golf cart lanes, a 10-foot raised median, two 11- foot travel lanes, and two 12-foot travel lanes. The proposed configuration will be consistent with the existing four-lane roadway section to the south, and the City’s current improvement project to the north (project number 2009-04), which will widen Dune Palms Road from two to four lanes with a median and left turn lanes. The proposed improvements will include a reconstruction of the north and south bridge approaches to accommodate the significant raised profile of the roadway. In order to match the roadway section on the south side of the bridge, the Project’s construction limits will be extended to 239 feet north of Highway 111 (Hwy 111). Construction in the ADI adjacent to prehistoric archaeological site P33-16950 will consist of raising and widening the roadway for the south bridge approach. This ESA Action Plan was prepared pursuant to Section 106 Programmatic Agreement Stipulation X.B.1.a and Attachment 5. Archaeological site P33-16950 is located east of Dune Palms Road and south of the Stormwater Channel within APN 600-030-018. An ESA will be established along the boundaries of parcel 600-030-018 (see Project Area Map and APE Map). 3.0 METHODS An Environmentally Sensitive Area (ESA) has been established for this Project. The ESA consists of entirety of the boundary of parcel 600-030-018, except on the western ESA Action Plan 3 Dune Palms Road October 2017 parcel boundary along Dune Palms Road where the fencing will follow the ADI boundary (see Project Area Map). Pre-field Activities Prior to beginning construction, the temporary ESA fence shall be installed of temporary orange fencing. ESA fencing will be installed along the entirety of the boundary of parcel 600-030-018, except on the western parcel boundary along Dune Palms Road where the fencing will follow the ADI boundary (see Project Area Map). Signage will be placed along the ESA fencing indicating that access is prohibited for construction equipment, storage or transport of materials or equipment personnel, or other project- related activities. The ESAs will be established through depiction on project plans, by defining these in the PS&E package, and as provided in the Project Engineer’s files. No Project-related activities shall occur within the ESAs. There will be no access to the ESA parcel from the shopping plaza to the east. Temporary Fence Temporary fence shall be furnished, installed, maintained, and later removed by the Contractor in conformance with the details shown on the plans, as specified in these special provisions, and as directed by the City Project Manager. Materials Used materials may be installed, provided the used materials conform to these special provisions. High Visibility Fabric High visibility fabric shall be machine-produced, orange-colored mesh manufactured from polypropylene or polyethylene. High visibility fabric may be made of recycled materials. Materials shall not contain biodegradable filler materials that can degrade the physical or chemical characteristics of the finished fabric. High visibility fabric shall be fully stabilized ultraviolet-resistant, shall be a minimum of 4 feet in width with a maximum mesh opening of 2" × 2". High-visibility fabric shall be furnished in one continuous width and shall not be spliced to conform to the specified width dimension. Posts Posts for temporary fence shall be of one of the following: ESA Action Plan 4 Dune Palms Road October 2017 A. Wood posts shall be fir or pine, shall have a minimum cross section of 2" × 2", and a minimum length of 5.50 feet. The end of the post to be embedded in the soil shall be pointed. Wood posts shall not be treated with wood preservative. B. Steel posts shall have a U, T, L, or other cross-sectional shape that resists failure from lateral loads. Steel posts shall have a minimum weight of 0.75 pounds per linear foot and a minimum length of 5.50 feet. One end of the steel post shall be pointed and the other end shall have a high visibility colored top. Fasteners Fasteners for attaching high visibility fabric to the posts shall be as follows: A. The high visibility fabric shall be attached to wooden posts with commercial quality nails or staples, or as recommended by the manufacturer or supplier. B. Tie wire or locking plastic fasteners shall be used for attaching the high-visibility fabric to steel posts. Maximum spacing of tie wire or fasteners shall be 24 inches along the length of the steel post. Signs The sign legend and dimensions shall be as shown on the plans. The sign shall read “Keep Out: Environmentally Sensitive Area” or similar language. The sign shall be weatherproof and fade proof and may include plastic laminated printed paper affixed to an inflexible weatherproof backer board. The sign panel shall be affixed to the high- visibility fabric with tie wire or locking plastic fasteners. The top of the sign panel shall be flush with the top of the high-visibility fabric. Sign panels shall be placed no more than 100 feet apart along the length of the temporary fence, and at each end of the fence. Installation Temporary fence shall be installed by the Contractor as follows: • All fence construction activities shall be conducted from outside the ESA as shown on the plans or as staked. • Posts shall be embedded in the soil a minimum of 16 inches. Post spacing shall be 8 feet maximum from center to center and shall at all times support the fence in a vertical position. • Temporary fence shall be constructed prior to any clearing and grubbing work. • Temporary fence shall be located so that it is visible, as determined by the Caltrans Archaeologist and City consulting archaeologist. • When the ESA temporary fence is no longer required, as determined by the City Project Manager, the temporary fence shall be removed and disposed of in conformance with state law. ESA Action Plan 5 Dune Palms Road October 2017 • Holes caused by the removal of temporary fence shall be backfilled and compacted and the ground will be returned to the pre-work condition to the extent possible. Maintenance Temporary fence that is damaged during the progress of the work shall be repaired or replaced by the Contractor the same day the damage occurs. Prior to beginning construction, approximately 765 linear feet of temporary ESA fence shall be installed along the entire APE boundary, as shown on the attached Project Area Map and in conformance with the provisions in Temporary Fence noted in this document. Installation of temporary ESA fencing will restrict access and minimize impact to the parcel. This temporary fence shall be furnished, installed, maintained, and later removed by the Contractor in conformance with the details shown on the plans, as specified in the special provisions, and as directed by the City Project Manager. Native American Monitoring, performed by the Agua Caliente Band of Cahuilla Indians approved monitor, will occur along Dune Palms Road as depicted in the attached map. The Monitoring shall be furnished by the City of La Quinta in accordance with a Monitoring Agreement between the City of La Quinta and the Agua Caliente Band of Cahuilla Indians. In the event that cultural resources are discovered during construction activities, all work shall temporarily stop within a sixty foot buffer of the discovery until a Qualified Archaeologist can assess the nature of the discovery. In the event that human remains are discovered, all work shall cease within a sixty foot buffer of the discovery and the Riverside County Sheriff will be notified immediately. In accordance with California Public Resources Code (PRC) §5097.98, if the Coroner determines that the remains are Native American in origin, the provisions of PRC §5097.98 shall be followed. No work within the discovery buffer will be permitted until authorized by a Qualified Archaeologist. Construction Monitoring In addition to the establishment of an ESA, an Archaeological Monitoring Area (AMA) has been established. The AMA consists of an 0.82-acre portion the APE where ground disturbance is proposed. An archaeological monitor and the Agua Caliente Band of Cahuilla Indians approved monitor will monitor the AMA for the presence of any archaeological findings during all ground- disturbing activities, including bore pit excavations, installation of pull boxes, over excavation, and conduit installation through a Monitoring Agreement between the City of La Quinta and the Agua Caliente Band of Cahuilla Indians. The City Project Manager will submit the required Monitoring Request Form to the THPO and work with the tribal monitor and the Contractor to set up inspections every day during these construction activities. The City’s Public Works ESA Action Plan 6 Dune Palms Road October 2017 Inspector will monitor activity in and around the AMA/ESA and will report to the City Project Manager. This will consist of a weekly visit and regular communication with the Contractor and the tribal monitor. Archaeological Discoveries In the event that archaeological discoveries are made during construction, activities within 60 feet of the discovery shall cease and the Contractor must immediately notify the City Project Manager and the City Consulting Archaeologist. The City Project Manager will notify the Caltrans Environmental Manager, Caltrans Archaeologist, Caltrans Architectural Historian, THPO, and City Consulting Archaeologist. No work will be allowed within the 60 foot buffer until authorized by a Qualified Archaeologist. The Caltrans Archaeologist will notify the State Historic Preservation Officer within 48 hours of any ESA breach and consult immediately to determine how the discovery will be addressed. Human Remains In the event that human remains are discovered during construction, all activities within 60 feet of the discovery shall cease and the County Sheriff Deputy Coroner shall be contacted immediately. Pursuant to Public Resources Code (PRC) §5097.98, if the remains are thought to be Native American, the coroner will notify the Native American Heritage Commission (NAHC) who will then notify the Most Likely Descendent (MLD). The Contractor must also immediately notify the City Project Manager and the City Consulting Archaeologist. The City Project Manager will notify the Caltrans Environmental Manager, Caltrans Archaeologist, Caltrans Architectural Historian, THPO, and City Consulting Archaeologist. No work will be allowed within the 60 foot buffer until authorized by a Qualified Archaeologist. Further provisions of PRC §5097.98 are to be followed as applicable. Monitoring Report At the end of ground disturbing construction activities of the Project, A Monitoring and Discovery Report shall be prepared and submitted to Caltrans and the Agua Caliente Band of Cahuilla Indians for review and approval. Once finalized, the report will be distributed to the City of la Quinta, the Agua Caliente Band of Cahuilla Indians, and any other consulting parties who have requested documents related to the Project. Ground-disturbing activities in the ADI south of the Stormwater Channel (the Archaeological Monitoring Area [AMA]) (see Project Area Map) will be monitored by an archaeologist and a Native American. The archaeological monitor will meet the Caltrans qualifications for a Lead Archaeological Surveyor and will be supervised by an archaeologist who meets Caltrans qualifications for a Co-Principal Investigator (Co-PI) ESA Action Plan 7 Dune Palms Road October 2017 for Archaeology. The Co-PI will be on-call to assess any finds. The Native American monitor will be approved by the Agua Caliente Band of Cahuilla Indians.
