Hi storical/Archaeological and Paleontological Resources Report _(TT 30487) Applicant: Santa Rosa Developers Archaeological Consultant: CRM TECH (Bruce Love, Principal) P:\CAROLYN\HPC6-20-02.wpd 4- 003 Historic Preservation Commission Minutes June 20, 2002 1. Principal Planner Stan Sawa presented the information contained in the staff report, a copy of which is on file in the Community Development Department. 2. Mr. Dave Brudvik, president of Santa Rosa Builders, stated he was unaware of any archaeological or historical items on the site. The property was formerly a date grove and most of the palm trees have been removed. He indicated he did not disagree with monitoring. 3. Commissioner Mouriquand recommended the monitoring requirement include any off site activity for trenching and other ground disturbance in relation to the project. 4. Commissioner Irwin clarified that any grading grubbing, trenching, excavations and/or other earth moving activities in the area should be monitored. 5. Commissioner Mouriquand explained that any off site activities necessary for the construction project, such as putting in water and sewer lines, are impacts which also need to be mitigated. 6. Mr. Brudvik asked if the monitoring would include construction activity after grading and utility lines were completed. 7. Commissioner Wright explained it was only required for mass grading, until the infrastructure was completed. He stated it was nice to have Commissioner Leslie Mouriquand involved with the Commission again as the commissioners had not thought about the off -site requirement, and her expertise was appreciated. He concurred with the staff report. 8. Commissioner Sharp pointed out that 11 prehistoric sites have been found nearby. He confirmed with Mr. Brudvik that the existing date grove on the adjacent property was slated for removal, and agreed with staff's recommendations. 9. Commissioner Irwin agreed with the CRM TECH report that it is a very rich area and merits monitoring. The stipulation for monitoring during grading, grubbing, trenching, excavation and other related off site earth moving activities should be added to the recommendation. .. 004 P:\CAROLYN\HPC6-20-O2.wpd -2- Historic Preservation Commission Minutes June 20, 2002 10. It was moved and seconded by Commissioners Wright/Sharp to adopt Minute Motion 2002-014 approving the Historical/Archaeological Resources Report for Tentative Tract 30487 as amended. Unanimously approved. a. Monitoring during grading, grubbing, trenching, excavation and other related off site earth moving activities will be required. 11. There being no further discussion, it was moved and seconded by Commissioners Wright/Sharp to adopt Minute Motion 2002-015 approving the Paleontological Resources Report for Tentative Tract 30487. Unanimously approved. a. Monitoring during grading, grubbing, trenching, excavation and other related off site earth moving activities will be required. B. Phase II Historical Study for Tentative Tract Mao 30550 Applicant: Dutch Parent, N.V. Archaeological Consultant: Archaeological Advisory Group (James Brock, RPA) Principal Planner Stan Sawa presented the information contained in the staff report, a copy of which is on file in the Community Development Department. 2. Kris Schultz of NRI Consulting and .and Mike Rowe, applicant, were present. Mr. Schultz pointed out that the recommendation to name the entry street from the intersection of Palm Royale Drive is merely a drive aisle and would probably not warrant a name. He also pointed out that emergency services usually do not like two segments of one street with different names. On the plan, it is indicated only as a short extension of Palm Royale Drive. The applicant has no objection to providing commemorative plaques for Iona T. Mackenzie and Raymond V. Darby. 3. Commissioner Wright concurred with staff's recommendations. He clarified with staff the Commission has no real authority for street naming. 005 P:\CAROLYN\HPC6-20-02.wpd -3- Historic Preservation Commission Minutes June 20, 2002 4. Staff explained that the street naming would be a recommendation for City Council consideration, and if the Council felt it unnecessary, it could be deleted. 5. Commissioner Wright agreed with staff's recommendations. 6. Commissioner Sharp found the report very interesting, and the stories fascinating. He said these anecdotes should be perpetuated through a display at the project. 7. Commissioner Irwin asked about the project plans. 8. Mr. Schultz explained the site is slated for commercial and high density residential. 9. Commissioner Irwin suggested that artwork could be added to the plan to reflect some of the history of the site in addition to the plaques. 10. Schultz pointed out that placement of artwork would be the responsibility of each developer who buys into the project. At this stage of planning, it would be impossible to accommodate such a requirement. 11. Commissioner Irwin stated she would like to see something on the property indicating the history of the area. The homesteads are important and as much of the history as possible should be preserved. 12. Mr. Rowe stated he would be more than happy to have the assistance of the Historic Preservation Commission to develop a package to provide to the developers of the property. 13. There being no further discussion, it was moved and seconded by Commissioners Wright/Sharp to adopt Minute Motion 2002-016 approving Phase II Historical Study for Tentative Tract 30550, the Dutch Parent project. Unanimously approved. 14. Schultz asked for clarification of the requirement of the Iona T. Mackenzie street name. 15. Commissioner Irwin read staff's recommendation that the road 006 P: \CARO LYN\H PC6-20-02. wpd -4- Historic Preservation Commission Minutes June 20, 2002 extending into the project, through the heart of the homestead, be changed to a name commemorating Iona T. Mackenzie. She questioned whether the recommendation should be eliminated. 16. Commissioner Wright stated he did not believe it should be eliminated. Having two names on a street is not unusual, and Ms. Mackenzie should be commemorated. 17. Commissioner Irwin expressed concern that no part of the project would have the "Mackenzie" name. 18. Commissioner Mouriquand explained the Commission can recommend a street name to the City Council, but if it's not a street there's a different issue. 19. Commissioner Irwin suggested the Commission recommend that if the access drive becomes a street, it should be named after Ms. Mackenzie. 20. Mr. Schultz showed the Commissioners the proposed plan. 21. Commissioner Irwin pointed out that since the plan proposes the access as Palm Royale Drive, it should be changed to Mackenzie Drive. 22. Staff confirmed that a street name change requires Council action, and he would see that it becomes part of the process. 23. Commissioners Wright/Sharp amended their motion to include: a. Palm Royale Drive be changed to Mackenzie Drive, 24. Staff clarified the street name change pertains only to the portion of Palm Royale Drive through the development in question, not the segment on the southern side of Fred Waring Drive. 25. Unanimously approved. C.

Principal Planner Stan Sawa presented the information contained in the staff report, a copy of which is on file in the Community Development Department. 2. Commissioner Mouriquand expressed concern that the authors of the archaeological reports had not contacted the Torres -Martinez Tribe or any other local tribal governments for comment. She understood it was something the City expected them to do as part of the background for the report. 3. Commissioner Wright concurred with staff's recommendations. He said it is a sensitive area and needs close monitoring. 4. Commissioner Sharp agreed and pointed out there should be no off -site requirement as the area is improved up to the property line. 5. Commissioner Mouriquand noted that something could be lying below the existing street. 6. Commissioner Irwin stated that when the original Del Oro development was constructed, monitoring was not required. Off site activity should definitely be monitored. She agreed with staff's recommendations. 7. There being no further discussion, it was moved and seconded by Commissioners Wright/Sharp to adopt Minute Motion 2002-017 approving the Phase I Cultural Resources Assessment of Tentative Tract 30521 as amended. a. Monitoring during grading, grubbing, trenching, excavation and other related off site earth moving activities will be required. D. A Phase I Cultural Resources Inventory for the Quarry Ranch Development ITT 30561) Applicant: Dean Palumbo, The Keith Companies for Winchester Development Archaeological / Historical Consultant: The Keith Companies (David Smith) 1.

Commissioner Mouriquand concurred with staff's recommendations. 3. Applicant's representative for The Keith Companies, Craig Lambert, who performed the first phase of the site testing, was present to answer any questions. 4. Commissioner Wright agreed with staff's recommendations and asked if there was a paved road to this site. 5. Mr. Lambert confirmed the pavement ends at the guard shack prior to the property line. 6. Commissioner Sharp concurred with staff's recommendations. 7. Commissioner Irwin noted she enjoyed the report and agreed with staff's recommendations. 8. There being no further discussion, it was moved and seconded by Commissioners Wright / Mouriquand to adopt Minute Motion 2002-018 approving the Phase I Cultural Resources Inventory for the Quarry Ranch Development, Tentative Tract 30561. 9. Commissioner Mouriquand asked if the Torres -Martinez Tribe was contacted. Mr. Lambert answered no. 10. Commissioner Sharp asked if the additional 9 holes of golf would be connected to the existing 18 holes of golf at the Quarry. Mr. Lambert stated he believed there were houses between the two courses. 11. Commissioner Mouriquand asked if trenching was planned. Mr. Lambert said no. Commissioner Mouriquand asked if the developer would submit a scope of work before testing. 12. Commissioner Wright pointed out that the scope of work is usually determined on a case -by -case basis. This particular area has been previously disturbed by flash flooding and other events over the years. 13. There being no further discussion, it was moved and seconded by Commissioners Wright/Mouriquand to adopt Minute Motion 2002- 018 approving the Phase I Cultural Resources Inventory for the Quarry Ranch Development, Tentative Tract 30561. Unanimously approved. P:\CAROLYN\HPC6-20-02.wpd -7- 009 Historic Preservation Commission Minutes June 20, 2002 VI. CORRESPONDENCE AND WRITTEN MATERIAL A. A brochure from the National Trust for Historic Preservation regarding the 2002 conference in Cleveland was provided for commissioners' perusal. VII. COMMISSIONER ITEMS A. Commissioner Irwin asked for clarification of the City of La Quinta Monitoring Program for CEQA Compliance which reads under Summary Mitigation Measures: "if artifacts are found during grading, stop and hire an archaeologist." She believes the statement is misleading. 1. Commissioner Wright agreed. All sites are supposed to be monitored anyway. 2. Commissioner Irwin suggested the sentence be reworded to indicate the proper focus. It could be a problem if this was the only reference a developer had seen. 3. Staff believed the statement was left in as a secondary reminder that monitoring should be on site. 4. Commissioner Wright suggested the wording be changed to "Stop and CONTACT the archaeologist," since there should be an archaeologist on site. 5. Staff will change the wording. B. Commissioner Wright asked Staff to include the requirement related to off -site activity in future reports. C. Commissioner Irwin officially welcomed Commissioner Mouriquand. VIII. ADJOURNMENT There being no further business, it was moved and seconded by Commissioners Wright / Mouriquand to adjourn this meeting of the Historic Preservation Commission to the next regularly scheduled meeting to be held on July 18, 2002. This meeting of the Historical Preservation Commission was adjourned at 4:05 p.m. Unanimously approved. Submitted by: Lynda J.

Phase I (survey level) cultural and paleontological resources assessments have been completed for this site which is a portion of proposed tentative tract application (TT 30834) for construction of a single family development. The assessment includes an archaeological, historical, and paleontological resources record search and field reconnaissance of the property. This assessment will be part of the environmental review required by the California Environmental Quality Act for the project application. DISCUSSION: Archaeological and Historical: This site is immediately to the east of a 15 acre parcel which will also become a part of TT 30834 and was previously surveyed and approved by the HPC on October 18, 2001 when it was proposed to be TT 29963 (see attached report). The new Tract 30834 includes the TT 29963 site and the two sites being considered at this meeting. As such, only a on -foot survey was needed and conducted. The intensive -level on -foot field survey of the study area did not result in any prehistoric sites, features, isolates, or evidence of objects, sites, features, or artifacts more than 50 years old. There was a scattering of modern trash found on the Oil p[\stan\hpc rpt ph 1 tt 30834-4.6 ac.wpd property. CRM TECH states that none of the items appear to be more than 50 years of age. Paleontological The paleontological assessment for the property to the west applies to this property as well, and therefore, only a on -foot field survey was conducted. During the field survey . scatters of fresh water shells and shell fragments were observed on the surface of the project area. Fresh water mollusks remains were also noted on the ground. However, no fish bone or other vertebrate fossil remains were found. CONCLUSIONS: The archaeological resources report notes the records search, the historical research, and archaeological field survey produced negative results and no historical resources more than fifty years old. Therefore, approval of the project will have no effect on any "historical resources" as defined by the California Environmental Quality Act (CEQA). The report states that no further investigation is recommended unless the project area is expanded or buried cultural materials are discovered during construction. The paleontological resources report concludes the project area has a moderate potential for Holocene vertebrate fossils and a high potential for Holocene Period invertebrate remains. As such, impacts created by the proposed project need to be mitigated pursuant to CEQA requirements. Paleontological monitoring during earth - moving activities is recommended in the report. RECOMMENDATIONS: Adopt Minute Motion 2002- , accepting the "Historical/Archaeological Resources Survey• APNs 762-240-009 and -010", as prepared by CRM TECH, subject to the following conditions: A. The site shall be monitored during rough grading and off -site trenching by a qualified archaeological monitor. B.

Box 11335 Palm Desert, CA 92255 ATTACHMENT #1 Ci f- j l_9 = , ,;A.bu "01P220L � RE: Historical/Archaeological Resources Survey: APNs 762-240-009 and -010, City of La Quinta, Riverside County, California. Dear Mr. Bruduik: In June, 2002, CRM TECH initiated a cultural resource study for APNs 762-240-009 and -010. At the beginning of the study, we determined that, in August and September, 2001, CRM TECH had already completed a historical/archaeological resources investigation of APN 762-240-009 along with the adjacent APNs 762-240-007 and -008 (Love et al. 2001) (Fig. 1). For that study CRM TECH conducted a historical/archaeological resources records search, pursued historical background research, and carried out an intensive -level field survey. Since that study was conducted on one parcel that is part of the current study area and on parcels adjacent to it, a new records search and the background research were not needed for the current study. Additionally, the findings of the current study may be considered as an addendum to that previous study. On June 19, 2002, CRM TECH archaeologist Daniel Ballester conducted an intensive -level on -foot field survey of APN 762-240-010. During the survey, Ballester walked parallel, north -south transects spaced 15 meters (ca. 50 feet) apart across the entire parcel. In some areas, especially near the middle and northern part of the property among the tamarisk trees and mesquite bushes, the vegetation was so thick that the ground visibility was close to zero percent; other areas were more open, however, with better ground visibility. During the survey, Ballester carefully examined the visible ground for any evidence of human activities dating to the prehistoric or historic periods (i.e., 50 years ago or older). Photographs of the project area were taken for visual documentation of the current conditions of the property. The intensive -level field survey of the project area completed during this and the previous study produced completely negative results for potential historical/archaeological resources. The ground surface was closely inspected during the survey for any signs of past human activities dating to the prehistoric or historic periods, but none was found. Vegetation, including large mesquite brush and creosote bushes, had been removed from the northeast corner of the project area not too long ago. An additional disturbance to the project area was evident along its southern boundary where dirt had been piled. Modern trash, including broken glass, cans, pieces of lumber, and plastic, was noted throughout the project area. Since all of these items are clearly less than 50 years old, they are of no historical/archaeological interest. In sum, no buildings, structures, objects, sites, features, 014 Tel. 909 784 3051 Fax 909 784 2987 Cell 909 376 7843 or artifacts from the prehistoric or the historic periods were noted on the subject property during the field survey. Through the various avenues of research, including a previous records search and historical background research, this study did not encounter any potential "historical resources," as defined by CEQA, within or adjacent to the project area. Therefore, CRM TECH recommends that the City of La Quinta may reach a finding of No Impact regarding cultural resources. No further cultural resources investigation is recommended for the proposed project unless project plans undergo such changes as to include areas not covered by this study. However, if buried cultural materials are encountered during construction, all work in that area should be halted or diverted until a qualified archaeologist can evaluate the nature and significance of the finds. Please let us know if we can be of further assistance.

CRM TECH Job # 852 Dear Mr. Bruduik: In June, 2002, CRM TECH initiated a cultural resource study for APNs 762-240-009 and -010. At the beginning of the study, we determined that, in August and September, 2001, CRM TECH had already completed a paleontological resources assessment of APN 762- 240-009 along with the adjacent APNs 762-240-007 and -008 (Love et al. 2001) (Fig. 1). For that study CRM TECH initiated records searches at the San Bernardino County Museum and the Natural History Museum of Los Angeles County, conducted a literature search, and carried out a field survey of the project area in accordance with the guidelines of the Society of Vertebrate Paleontology. Since that study was conducted on one parcel that is part of the current study area and on parcels adjacent to it, a new records search and the literature search were not needed for the current study. Additionally, the findings of the current study may be considered as an addendum to that previous study. On June 18, 2002, CRM TECH geologist/paleontologist Harry M. Quinn conducted the field assessment of APN 762-240-010. The survey was carried out by walking the property in both east -west and north -south transects as well as walking in and around the thickets of brush that exist on the property. Special attention was paid to blow-out areas, many of which contain lag deposits of shell material. During the field survey, scattered Anodonta sp., Gyraulus sp., Physa sp., and Tryonia sp. shells and shell fragments were observed on the surface of the project area, with Physa sp. appearing to dominate. In blow-out areas, the Physa sp. and Tryonia sp. were seen as localized shell lag deposits. While fresh water mollusks were noted during the survey, no fish bone or other vertebrate fossil remains were found. The presence of the fresh water mollusks, especially when found as paired valves, confirms that the sediments found in the project area can be attributed to Holocene Lake Cahuilla lakebed sequences. As with other areas within the former lakebed, vertebrate fossil remains are rare or even non-existent, except where interbedded fluvial deposits might be present. Based on the various avenues of research, including the previous records searches and literature search, the proposed project's potential impact on Holocene vertebrate fossils is determined to be moderate, while the potential impact on Holocene invertebrate fossils is high. Therefore, on -site monitoring for paleontological resources is recommended. 017 Tel. 909 784 3051 Fax 909 784 2987 Cell 909 376 7843 Please let us know if we can be of further assistance.

Phase I (survey level) cultural and paleontological resources assessments have been completed for this site which is a portion of a proposed tentative tract application (TT 30834) for construction of a single family development. The assessment includes an archaeological, historical, and paleontological resources record search and field reconnaissance of the property. This assessment will be part of the environmental review required by the California Environmental Quality Act for the project application. DISCUSSION: Archaeological and Historical: An archaeological records search for the property was conducted at the Eastern Information Center located at UC Riverside. The records search indicated that the west half of the study area had been previously surveyed for cultural resources in 1983, but no archaeological sites were recorded within or adjacent to the project area. Within a one-half mile radius of the property 16 area -specific cultural resources studies have been conducted, including on the properties immediately to the north and south and along 58T" Avenue (linear study). As a result of these studies, eleven prehistoric archaeological sites and one historic -era site have been recorded. The prehistoric sites consist primarily of scatters of lithic and ceramic scatters, although a fire 020 pf\stan\hpc rpt ph 1 tt 30834.wpd hearth/roasting fire pit feature was noted at one of the sites. None of these previously recorded sites is located in the vicinity of the project area. Historical background research was conducted at the Science Library Map Room at UC Riverside and at the Bureau of Land Management (BLM) Office in Riverside. The search did not indicate any use of the property to the present day. The intensive -level on -foot field survey of the study area did not result in any prehistoric sites, features, isolates, or evidence of objects, sites, features, or artifacts more than 50 years old. There was a scattering of modern trash found on the property. CRM TECH states that none of the items appear to be more than 50 years of age. Paleontological: The project area is at an elevation of approximately 30 feet below sea level. Holocene or ancient Lake Cahuilla has at least seven times in the past covered much of the project and surrounding area. The last high water elevation of the lake was at 42 feet above sea level. Therefore, the project area has been under water in the past. Based on previous discoveries reported nearby, the San Bernardino County Museum considers the project area to have a "high paleontological sensitivity" which has a high potential to impact significant nonrenewable fossil resources, primarily invertebrate fossils. During the field survey scatters of fresh water shells and shell fragments were observed on the surface of the project area. Fresh water mollusks remains were also noted on the ground. However, no fish bone or other vertebrate fossil remains were found. CONCLUSIONS: The archaeological resources report notes the records search, the historical research, and archaeological field survey produced negative results and no historical resources more than fifty years old. Therefore, approval of the project will have no effect on any "historical resources" as defined by the California Environmental Quality Act ICEQA)• The report states that no further investigation is recommended unless the project area is expanded or buried cultural materials are discovered during construction. The paleontological resources report concludes the project area has a high potential for Holocene Period invertebrate remains. As such, impacts created by the proposed project need to be mitigated pursuant to CEQA requirements. A Phase 2 surface collection of the fresh water mollusk should be under taken. Additionally, paleontological monitoring during earth -moving activities and preparation of a final report on the monitoring is recommended in the report. 021 p[\stan\hpc rpt ph 1 tt 30834.wpd RECOMMENDATIONS: 1.

The subject property of the study, Tentative Tract No. 30566, consists of three existing parcels, APNs 762-240-004, -005, and -006, located on the north side of Avenue 58 between Jefferson and Madison Streets. It is a portion of the southeast quarter of the southwest quarter of Section 21, T6S R7E, San Bernardino Base Meridian. The study is part of the environmental review process for a proposed residential development known as Coral Mountain Resort, to be undertaken partially on the subject property. The City of La Quinta, as Lead Agency for the project, required the study in compliance w ith the California Environmental Quality Act (CEQA) and the City's Historic Preservation Ordinance. The purpose of the study is to provide the City of La Quinta with the necessary information and analysis to determine whether the proposed development would cause substantial adverse changes to any historical/ archaeological resources that may exist in or around the project area, as mandated by CEQA. In order to identify and evaluate such resources, CRM TECH conducted a historical/archaeological resources records search, pursued historical background research, and carried out an intensive -level field survey. Through the various avenues of research, this study did not encounter any potential "historical resources," as defined by CEQA, within or adjacent to the project area. Therefore, CRM TECH recommends that the City of La Quinta may reach a finding of No Impact regarding cultural resources. No further cultural resources investigation is recommended for the proposed project unless project plans undergo such changes as to include areas not covered by this study. However, if buried cultural materials are encountered during construction, all work in that area should be halted or diverted Until a qualified archaeologist can evaluate the nature and significance of the finds. . . 024 .Jml 31,02 01:50p CRMfECH 90 842987 p.4 TABLE OF CONTENTS MANAGEMENT SUMMARY .................................................

The subject property of the study, Tentative Tract No. 30566, consists of three existing parcels, APNs 762-240-004, -005, and -006, located on the north side of Avenue 58 between Jefferson and Madison Streets (Fig. 2). It is a portion of the southeast quarter of the southwest quarter of Section 21, T6S R7E, San Bernardino Base Meridian (Fig. 2). The study is part of the environmental review process for a proposed residential development known as Coral Mountain Resort, to be undertaken partially on the subject property. The City of La Quinta, as Lead Agency for the project, required the study in compliance with the California Environmental Quality Act (CEQA; PRC §21000 et seq.) and the City's Historic Preservation Ordinance (Title 7, La Quinta Municipal Code). CRM TECH performed the present study to provide the City of La Quinta with the necessary information and analysis to determine whether the proposed development would cause substantial adverse changes to any historical/archaeological resources that may exist in or around the project area, as mandated by CEQA. In order to identify and evaluate such resources, CRM TECH conducted a historical/archaeological resources records search, pursued historical background research, and carried out an intensive -level field survey. The following report is a complete account of the methods, results, and final conclusion of the study. Figure 1, Project vicinity.

Dictated by this geographic setting, the project area and its environs are marked by extremes in temperature and aridity. Temperatures in the region reach over 120 degrees in summer, and dip to near freezing in winter while average annual precipitation is less than five inches. The project area lies at an elevation of approximately 30 feet below sea level. It is relatively level except near the center of the property, where several small depressions are located. Brick walls and a chain -link fence mark its northern and western limits, and Avenue 58 runs along the southern boundary. The land is partly open and partly covered by dense growths of tamarisk and mesquite, along with moderate stands of salt bush and arrowweed (Fig. 3). The vegetation is especially thick in the northern portion of the project area, while the central portion has been largely cleared (Fig. 3). The southern portion, meanwhile, has apparently been disturbed by heavy equipment. A number of dirt roads are found in the project area. CULTURAL SETTING Ethnohistoric Context The Coachella Valley is a historical center of Native American settlement, where U.S. surveyors noted large numbers of Indian villages and rancherfas, occupied by the Cahuilla people, in the mid-19th century. The Cahuilla, a Takic-speaking people of hunters and gatherers, are generally divided by anthropologists into three groups, according to their geographic setting: the Pass Cahuilla of the San Gorgonio Pass -Palm Springs area, the Mountain Cahuilla of the San Jacinto and Santa Rosa Mountains and the Cahuilla Valley, and the Desert Cahuilla of the eastern Coachella Valley. The Cahuilla did not have a single name that referred to an all-inclusive tribal affiliation. Instead, membership was in terms of lineages or clans. Each lineage or clan belonged to one of two main divisions of the people, known as moieties. Members of clans in one Figure 3. Typical landscapes in the project area. Left: dense vegetation in the northern portion; right: cleared area in the central portion. 028 moiety had to marry into clans from the other moiety. Individual clans had villages, or central places, and territories they called their own, for purposes of hunting game, gathering food, or utilizing other necessary resources. They interacted with other clans through trade, intermarriage, and ceremonies. Population data prior to European contact are almost impossible to obtain, but estimates range from 3,600 to as high as 10,000 persons. During the 19th century, however, the Cahuilla population was decimated as a result of European diseases, most notably smallpox, for which the Native peoples had no immunity. Today, Native Americans of Desert and Pass Cahuilla heritage are mostly affiliated with one or more of the Indian reservations in the Coachella Valley, including Torres Martinez, Augustine, Cabazon, Agua Caliente, and Morongo, most of which are located in close proximity to the City of La Quinta. Historic Context In 1823-1825, Jose Romero, Jose Maria Estudillo, and Romualdo Pacheco, leading an expedition in search of a route to Yuma, became the first noted European explorers to travel through the Coachella Valley. However, due to its harsh environment, few non - Indians ventured into the desert valley during the Mexican and early American periods, except those who traveled across it along the established trails. The most important among these trails was the Cocomaricopa Trail, an ancient Indian trading route that was "discovered" in 1862 by William David Bradshaw and became known after that as the Bradshaw Trail. In the Coachella Valley, this historic wagon road traversed a course that is very similar to present-day Highway 111. During the 1860s-1870s, the Bradshaw Trail served as the main thoroughfare between coastal southern California and the Colorado River, until the completion of the Southern Pacific Railroad in 1876-1877 brought an end to its heyday. Non -Indian settlement in the Coachella Valley began in the 1870s, with the establishment of railroad stations along the Southern Pacific Railroad, and spread further in the 1.880s, after public land was opened for claims under the Homestead Act, the Desert Land Act, and other federal land laws. Farming became the dominant economic activity in the valley, thanks to the development of underground water sources, often in the form of artesian wells. But it was not until the completion of the Coachella Canal in 1948-1949 that farmers in the and region obtained an adequate and reliable water supply. The main agricultural staple in the Coachella Valley, the date palm, was first introduced around the turn of the century. By the late 1910s, the date palm industry had firmly established itself, giving the region its celebrated image of "the Arabia of America." Starting in the 1920s, a new industry, featuring equestrian camps, resort hotels, and eventually country clubs, gradually spread throughout the Coachella Valley, and since then transformed it into southern California's leading winter retreat. In today's City of La Quinta, the earliest settlement and land development activities did not occur until the turn of the century. In 1926, with the construction of the La Quinta Hotel, the development of La Quinta took on the character of a winter resort, typical of the desert communities along Highway 111. Beginning in the early 1930s, the subdivision of the cove area of La Quinta and the marketing of "weekend homes" further emphasized this new direction of development. On May 1,1982, La Quinta was incorporated as the 19th city in Riverside County. 4 029 13•d L86Z4 6n6 H331 d?J3 dZS:rn 00 ZE inC' RESEARCH METHODS RECORDS SEARCH On March 12, 2002, CRM TECH archaeologist Mariam Dandul (see App.1 for qualifications) conducted the historical/archaeological resources records search at the Eastern Information Center (EIC), University of California, Riverside. During the records search, Dandul examined maps and records on file at the EIC for previously identified cultural resources in or near the project area, and existing cultural resources reports pertaining to the vicinity. Previously identified cultural resources include properties designated as California Historical Landmarks, Points of Historical Interest, or Riverside County Landmarks, as well as those listed in the National Register of Historic Places, the California Register of Historical Resources, or the California Historical Resource Information System. HISTORICAL RESEARCH Historical research for this study was conducted by CRM TECH historian Bai "Toni' Tang (see App.1 for qualifications) on the basis of published literature in local and regional history and historic maps of the La Quinta area. Among maps consulted for this study were the U.S. General Land Office's (GLO) land survey plat maps dated 1856 and 1903, and the U.S. Geological Survey's (USGS) topographic maps dated 1904,1941, and 1956-1959. These maps are collected at the Science Library of the University of California, Riverside, and the California Desert District of the U.S. Bureau of Land Management, also located in Riverside. FIELD SURVEY On March 19, 2002, CRM TECH archaeologist Daniel Ballester (see App. 1 for qualifications) carried out the intensive -level field survey of the project area. During the survey, Ballester walked parallel east -west transects at 15-meter (ca. 50-foot) intervals across the southern and central portions of the project area, as well as most of the northern portion. Areas with impenetrably dense vegetation were inspected around the perimeters and spot-checked wherever possible. Following this approach, the ground surface was examined systematically for any evidence of human activities dating to the prehistoric or historic periods (i.e., 50 years ago or older). RESULTS AND FINDINGS RECORDS SEARCH RESULTS According to records on file at the Eastern Information Center, the western half of the project area was previously surveyed for cultural resources in 1983, but no archaeological sites or other cultural resources were recorded on or adjacent to the property (Paden 1983). Within a one -mile radius of the project area, EIC records indicate that a total of 16 other previous cultural resources studies have taken place on various tracts of land and linear features, including a linear study along Avenue 58 (Fig. 4). 030 AM, Am 6•d L86Zb 606 H031 83 des:10 20 1E IBC' r v EL n p �E Scope of records '� }A a search 22 �� !1 w r• � p41 q, �� JII„f' 1 .i ,.1 :r�r� -a. k n y ,� • A. �L MIS � .i� a.. 1_ I � L OIIhW parM1 °t. .��i �e.

The prehistoric sites consisted of scatters of lithic and ceramic artifacts, fire hearths, habitation debris, bedrock milling features, and petroglyphs. The historic -era site was recorded as an abandoned adobe residence of unknown age with several associated loci, including a foundation, wells/cisterns, and a trash scatter, which were interpreted as a site of long-term occupation dating from circa 1915 to the 1960s. None of these previously recorded sites were located in the immediate vicinity of the project area. Therefore, none of them requires further consideration during this study. Although the western half of the project area has been surveyed for cultural resources in the past, that survey is now nearly 20 years old. Pursuant to EIC and City policies, it was determined that a systematic re -survey of the entire project area would be necessary for the present study. HISTORICAL RESEARCH RESULTS Based on historical maps consulted for this study, the project area appears to be rather low in sensitivity for cultural remains dating to the historic period. As Figures 5-7 illustrate, from the 1850s to the early 20th century, the only man-made feature observed in the vicinity by the various U.S. government surveyors was a road traversing just under a mile to the east of the project area. Identified in 1903 as the "Road from Indian Wells to Torres" (Fig. 7), this road was clearly a part of the Cocomaricopa-Bradshaw Trail Qohnston 1987:115-120).

(Source: USGS 1941a;1941b) Despite its proximity to this historic transportation artery, no evidence of any settlement or land development activities was found in or near the project area in the 19th and early 20th centuries (Figs. 5-7)• By the early 1940s, scattered buildings, presumably farmsteads, had appeared in the vicinity of the project area, connected to one another by crisscrossing roads (Fig. 8), a development pattern typical of rural areas in the Coachella Valley at that time. During the next two decades, Avenue 58 came into being along the southern edge of the project area (Fig. 9). Nevertheless, the project area itself apparently remained vacant and undeveloped to the present time (USGS 1980 [Fig. 2]). FIELD SURVEY RESULTS The intensive -level field survey of the project area produced completely negative results for potential historical/ archaeological resources.

A large amount of modem trash was noted throughout the project area, especially along the western boundary. Since all of these items are clearly less than 50 years old, they are of no historical/archaeological interest. In sum, no buildings, structures, objects, sites, features, or artifacts more than 50 years of age were encountered on the subject property during the survey. DISCUSSION The purpose of this study is to identify any cultural resources within or adjacent to the project area, and to assist the City of La Quinta in determining whether such resources meet the official definitions of "historical resources," as provided in the California Public Resources Code, in particular CEQA. According to PRC §5020.10), "'historical resource' includes, but is not limited to, any object, building, site, area, place, record, or manuscript which is historically or archaeologically significant, or is significant in the architectural, engineering, scientific, economic, agricultural, educational, social, political, military, or cultural annals of California." More specifically, CEQA guidelines state that the term "historical resources" applies to any such resources listed in or determined to be eligible for listing in the California Register of Historical Resources, included in a local register of historical resources, or determined to be historically significant by the Lead Agency (Title 14 CCR §15064.5(a)(1)-(3)). Regarding the proper criteria for the evaluation of historical significance, CEQA guidelines mandate that "a resource shall be considered by the lead agency to be 'historically significant' if the resource meets the criteria for listing on the California Register of Historical Resources" (Title 14 CCR §15064.5(a)(3)). A resource may be listed in the California Register if it meets any of the following criteria: (I) Is associated with events that have made a significant contribution to the broad patterns of California's history and cultural heritage. (2) Is associated with the lives of persons important in our past. (3) Embodies the distinctive characteristics of a type, period, region, or method of construction, or represents the work of an important creative individual, or possesses high artistic values. (4) Has yielded, or may be likely to yield, information important in prehistory or history. (PRC §5024.1(c)) A local register of historical resources, as defined by PRC §5020.1(k), "means a list cf properties officially designated or recognized as historically significant by a local government pursuant to a local ordinance or resolution." For properties within the City of La Quinta, the City's Historic Preservation Ordinance (Title 7, La Quinta Municipal Code) provides for the establishment of a historic resources inventory as the official local register. A historic resource may be considered for inclusion in the historic resources inventory based on one or more of the following: A. It exemplifies or reflects special elements of the city's cultural, social, economic, political, aesthetic, engineering or architectural history; or 034 CT -Cl L66Zb6It 6 H03-L 110 d89--10 aO SE'inr ' B. It is identified with persons or events significant in local, state or national history; or C. It embodies distinctive characteristics of a style, type, period or method of construction, is a valuable example of the use of the indigenous materials or craftsmanship or is representative of a notable work of an acclaimed builder, designer or architect; or D. It is an archaeological, paleontological, botanical, geological, topographical, ecological or geographical site which has the potential of yielding information of scientific value; or E. It is a geographically definable area possessing concentration of sites, buildings, structures, improvements or objects linked historically through location, design, setting, materials, workmanship, feeling and/or association, in which the collective value of the improvements may be greater than the value of each individual improvement. (LQNIC §7.06.020) As stated above, the records search, the historical research, and the field survey conducted during this study have all produced negative results, and no potential historical/ archaeological resources more than 50 years of age were discovered in or near the project area. Based on these findings, and in light of the criteria listed above, the present study concludes that no historical resources exist within or adjacent to the project area. RECOMMENDATIONS CEQA establishes that "a project that may cause a substantial adverse change in the significance of a historical resource is a project that may have a significant effect on the environment" (PRC §21084.1). 'Substantial adverse change," according to PRC §5020.1(q), "means demolition, destruction, relocation, or alteration such that the significance of an historical resource would be impaired." Since no historical resources were encountered during the course of this study, Ch:M TECH presents the following recommendations to the City of La Quinta: No historical resources exist within or adjacent to the project area, and thus the project as currently proposed will cause no substantial adverse change to any known historical resources. No further cultural resources investigation is necessary for the proposed project unless project plans undergo such changes as to include unstudied areas. If buried cultural materials are discovered during construction, all work in that area should be halted or diverted until a qualified archaeologist can evaluate the nature and significance of the finds. CONCLUSION The foregoing report has provided background information on the project area, outlined the methods used in the current study, and presented the results of the various avenues of research. Throughout the course of the study, no 'historical resources," as defined by CEQA, were encountered within or adjacent to the project area. Therefore, CRM TECH recommends that the City of La Quinta may reach a finding of No Impact regarding cultural resources, with the condition that any buried cultural materials unearthed during future development are to be examined and evaluated by a qualified archaeologist prior to further disturbances. 10 (13 5 i,I•d LBSails 4 Nos H031980 dBS:IO 20 iB inr REFERENCES GLO (General Land Office, U.S. Department of the Interior) 1856 Plat Map: Township No. 6 South Range No. 7 East, San Bernardino Meridian; surveyed in 1856. 1903 Plat Map: Township No. 6 South Range No. 7 East, San Bernardino Meridian, California; surveyed in 1903.

The subject property of the study, Tentative Tract No. 30566, consists of three existing parcels, APNs 762-240-004, -005, and -006, located on the north side of Avenue 58 between Jefferson and Madison Streets. It is a portion of the southeast quarter of the southwest quarter of Section 21, T6S R7E, San Bernardino Base Meridian. The study is part of the environmental review process for a proposed residential development known as Coral Mountain Resort, to be undertaken partially on the subject property. The City of La Quinta, as Lead Agency for the project, required the study in compliance with the California Environmental Quality Act (CEQA). The purpose of the study is to provide the City of La Quinta with the necessary information and analysis to determine whether the proposed development would potentially disrupt or adversely affect any paleontological resources, as mandated by CEQA, and to design a paleontological salvage program for the project, if necessary. In order to identify any paleontological resource localities that may exist in or near the project area and to assess the possibility for such resources to be encountered in future excavation and construction activities, CRM TECH initiated records searches at the San Bernardino County Museum and the Natural History Museum of Los Angeles County, conducted a literature search, and carried out a field survey of the project area in accordancewith the guidelines of the Society of Vertebrate Paleontology. Based on the findings from these research procedures, the proposed project's potential impact on paleontological resources is determined to be high for Holocene age invertebrate fossils. Therefore, CRM TECH recommends that grading, grubbing, trenching, excavations, and/or other earth -moving activities in the project area be monitored for paleontological resources, and that a mitigation program be implemented to address potential impacts to any paleontological deposits that are unearthed. 041 Jul 31 02 02:00p CRM TECH . . . �� ��� �� 9097842987 p.21 TABLE OF CONTENTS MANAGEMENTSUMMARy INTRODUCTION ����,~.��,.�~..�~.�.���.°^.

The subject property of the study, Tentative Tract No. 30566, consists of three existing parcels, APNs 762-240-004, -005, and - 006, located on the north side of Avenue 58 between Jefferson and Madison Streets (Fig. 2). It is a portion of the southeast quarter of the southwest quarter of Section 21, T6S R7E, San Bernardino Base Meridian (Fig. 2). The study is part of the environmental review process for a proposed residential development known as Coral Mountain Resort, to be undertaken partially on the subject property. The City of La Quinta, as Lead Agency for the project, required the study in compliance with the California Environmental Quality Act (CEQA). CRM TECH performed the present study to provide the City of La Quinta with the necessary information and analysis to determine whether the proposed development would potentially disrupt or adversely affect any paleontological resources, as mandated by CEQA, and to design a paleontological salvage program for the project, if necessary. In order to identify any paleontological resource localities that may exist in or near the project area and to assess the possibility for such resources to be encountered in future excavation and construction activities, CRM TECH initiated records searches at the San Bernardino County Museum and the Natural History Museum of Los Angeles County, conducted a literature search, and carried out a field survey of the project area in accordance with the guidelines of the Society of Vertebrate Paleontology.

The Colorado Desert province is bounded on the southwest by the Peninsular ranges, on the north by the eastern Transverse Ranges province, and on the northeast by the Mojave Desert province (Jenkins 1980:40-41). The province widens to the southeast through the Imperial Valley and into Mexico. One of the major features to be found within the Colorado Desert province is the Salton Trough, a 290-kilometer-long (ca. 180 miles) structural depression containing the present day Salton Sea. This depression extends from the Banning Pass area southward into Mexico. During Pleistocene and Holocene times, the northwestern portion of this trough was filled with over 4,000 feet of sediments (Proctor 1968). While the term "Salton trough" refers to the entire structural depression from the San Gorgonio Pass to the Gulf of California, the term "Salton Sink" is used to describe that portion of the area that drains directly into the Salton Sea. The Salton Sea, therefore, occupies the Salton Basin portion of the Salton Trough. Holocene Lake Cahuilla occupied a much larger portion of the Salton Basin than that of the present day Salton Sea (Rogers 1965). The shoreline of the last ancient lake to fill the basin can be seen today as a line along the base of the Santa Rosa Mountains at an elevation of about 42 feet above sea level (Waters 1983; Wilke 1978). Based on radiocarbon dating the last high stand of Holocene Lake Cahuilla was about 1680 (Laylander 1997; Quinn 2002; Rockwell 1995;1997). The field survey found the property to have a wall/fence along the west and north sides, a series of tamarisk -mesquite thickets along the northwest and north portions, some arrowweed and dead reeds in a north -central portion, and a moderate stand of salt bush over the remainder of the property. There are also a few large dead mesquites and some smaller living mesquites scattered around the south half of the property. The property is partly open and partly covered by dense growths of tamarisk/mesquite and moderate stands of salt bush and arrowweed. Soil exposures are only available between and around the tamarisk/mesquite thickets and in the low areas between the salt bushes. There has been some brush clearing near the central portion of the property, which is connected to the street by a dirt road. The sediments present on this property are fine sandy loam and silty loam. METHODS AND PROCEDURES RECORDSSEARCHES The paleontological records searches used for this study were originally conducted in August, 2001, for a property immediately to the west of the project area. The records search service was provided by the Regional Paleontologic Locality Inventory located at OI 75 Jul 31 02 02:03p CRM TECH 90a2842987 p.25 TAW the San Bernardino County Museum in Redlands and the Natural History Museurn of Los Angeles County in Los Angeles. These institutions maintain files of regional paleontological site records as well as supporting maps and documents. The records search results are used to identify previously performed paleontological resource assessments and known paleontological localities near the project area. In addition, a literature search was conducted using materials in the CRM TECH library and the personal library of the author, including unpublished reports produced from surveys of other properties in the vicinity. FIELD SURVEY On March 2.2, 2002, CRM TECH geologist/paleontologist Harry M. Quinn (see App.1 for qualifications) conducted the field assessment of the project area. The survey was carried out by walking across the project area along north -south transects, while avoiding the thickets of tamarisk and mesquite. RESULTS AND FINDINGS EXISTING DATA SUMMARY The paleontology records searches indicate that no paleontological localities have been discovered within the boundaries of that property but sites are known from within a one - mile radius of the current project area (Scott 2001; McLeod 2001). In addition, several paleontological localities previously reported within and outside of the one -mile radius are known to have produced fossils from sediment lithologies similar to those in the project area (ibid.). Based on these previous discoveries, the San Bernardino County Museum assigns the project area a "high paleontological sensitivity" and declares the proposed project to have a "high potential to impact significant nonrenewable fossil resources," primarily Holocene age lacustrine invertebrate fossils (Scott 2001). Whistler et al. (1995) reports the discovery of terrestrial vertebrate remains at a locality a short distance to the north of this property and from similar sediment lithologies. That locality is characterized by interbedded sediments of lacustrine and fluvial origin, and it is not clear which interval the terrestrial fauna came from. Since terrestrial faunas do not live in lacustrine environments, the terrestrial vertebrate remains most likely came from the fluvial sediments. The project area does lie close to the old shoreline of ancient Lake Cahuilla, so may have similar stratigraphy to that present at the PGA West Tom Weiskopf Signature Golf Course site reported by Whistler et al (1995). Padon (1983) incorrectly dated the lake bed sediments as being Pleistocene through early Holocene in age. These ages were apparently based on calcareous tufa dates by Reynolds (ibid.), a material that results in very questionable radiometric dates (Quinn 2000a:5-6). Scott (2001:1) dates the Holocene Lake Cahuilla as having been present from 470 years before present to at least around 6,000 years before present, making them late Holocene in age. More recent data suggests that the last high stand (the 12-meter mark) only ended about 320 years before present (Laylander 1997; Quinn 2002; Rockwell 1995;1997; Von Werlhof 2001:26). 11. 046 ,Jul 31 02 02:04p CRM TECH 90842987 p.26 1. GEOLOGY The onsite geology is mapped by Rogers (1965) as Q1-Qal, or Quaternary lake deposits and Recent alluvium. Jahns (1954) mapped the site geology as Qal, or Recent alluvial -fan, flood - plain, swamp, lake, and sand dune deposits. The soils present on this property are mapped as GbA, GcA, and Is (Knecht 1980:Map Sheet 12). The 1975 aerial photograph on which the soils have been mapped shows the property to be open undeveloped land. The property is crossed by a northwest -southeast trending channel at the north end containing a dense growth of brush/trees. These areas match very well with the tamarisk and mesquite thickets observed during the field inspection. The GbA type soil is identified as the Gilman fine sandy loam with 0 to 2 percent slopes (Knecht 1980:17). It is described as a nearly level soil with a profile similar to the one described as representative of the Gilman series (ibid.). The representative profile to 60 inches (about 1.5 meters) below the surface is shown to be loose, nonsticky, and nonplastic very fine sand with some silt and clay with common scattered shells and shell fragments (ibid.). The GcA type soil is identified as the Gilman fine sandy loam, wet, 0 to 2 percent slopes (Knecht 1980:18). It is described as a nearly flat soil found on alluvial fans and flood plains of the Coachella Valley. It has the profile described as representative of the series and usually has a water table between 40 and 60 inches (ibid.) The representative profile to 60 inches (about 1.5 meters) below the surface is shown to be loose, nonsticky, and nonplastic very fine sand with some silt and clay with common scattered shells and shell fragments (Knecht 1980:17). The Is type soil is identified as the Indio very fine sandy loam (Knecht 1980:21). It is described as a nearly level soil that has a profile similar to the one described as representative of the series, but the water table is below 6 feet (ibid.). The Indio Series soils in general are described by Knecht (1980:21) as, "Typically, the surface layer is light brownish gray, very fine sandy loam about 10 inches thick. The substratum to a depth of 60 inches or more is light brownish gray, highly micaceous very fine sandy loam stratified with silt and silt loam. It contains a few freshwater shells. The soil is moderately alkaline and strongly effervescent." These soils are found within the old lake bed portion of the Coachella Valley. The above soils indicate nearness to the Holocene Lake Cahuilla shoreline, where alluvial sediments may be interbedded with lacustrine sediments. The field survey confirmed the presence of fresh water shell material, supporting the fact that the property lies within the old Holocene Lake Cahuilla lake bed. No vertebrate fossils were found. PALEONTOLOGY During the field survey scattered Tryonia sp., Anodonta sp., Physa sp., and a few Gyraulus sp. shells and shell fragments were observed on the surface of the project area. While fresh water mollusks were found during the survey, no fish bone or other vertebrate fossil remains were noted. In blowout areas, the Physa sp. and Tryonia sp. often form localized shell lag deposits. The fresh water mollusks located during the field survey reinforce the 5 047 Jul 31 02 02:04p CRM TECH 90 842987 p.27 AM presence of sediments that can be attributed to Holocene Lake Cahuilla lakebed sequence. As with other areas within the former lakebed, vertebrate fossil remains are rare to non- existent. DISCUSSION The field survey results, supported by literature research, indicate that the project area contains sediments deposited by Holocene Lake Cahuilla. Fossil fresh water mollusks located during the field survey reinforce the presence of sediments that can be attributed to this ancient lakebed sequence, which have a low potential for vertebrate fossil remains, but a high potential for invertebrates, such as freshwater mollusks. Many Holocene paleontological localities are known from the ancient Lake Cahuilla sediments. Specimens from most of these localities usually consist only of fresh water mollusks, except in one instance where invertebrates, such as gastropods (snails) and pelecypods (clams and mussels), and vertebrate remains of fish, birds, reptiles, amphibians, and plants were also found (Whistler et al.1995:109-118). However, the fresh water mollusks are almost the only fauna found within the lakebeds sediments themselves. The San Bernardino County Museum reports the presence of paleontological resource localities within a half -mile radius of the project area (Scott 2001). However, no precise location for these sites is shown. These localities have produced mainly freshwater mollusks from Holocene Lake Cahuilla, but also listed are some other invertebrate, plant and vertebrate fossils. The Natural History Museum of Los Angeles reports the presence of a fossil locality just north of Indio (McLeod 2001). This site coincides with the sites reported by the San Bernardino County Museum. No Pleistocene age fossil localities have been reported from the lakebeds or their equivalent strata within the Coachella Valley area. A preliminary study of soil borings drilled for engineering purposes indicates that at least the upper 25 feet (ca. 7.6 meters) of sediments within the lower Coachella Valley are Holocene in age. A few borings have been drilled to 50 feet (ca.15.2 meters) below grade without encountering any Pleistocene sediments. It is therefore doubtful that any Pleistocene fossils, vertebrate or invertebrate, will be recovered from the lower Coachella Valley area during normal grading operations. Thus paleontological monitoring of deep trenching for utility lines should be given greater consideration than monitoring during grading operations, and even these utility trenches generally do not go deep enough to reach Pleistocene sediments. The nearest Pleistocene and older fossil -bearing sediments are known to be present along the up -thrown side of the San Andreas Fault System, such as in the Indio and Mecca Hills (Diblee 1954:21-28). Here, a small number of early Pleistocene vertebrate fossils have been found in outcrop. Some vertebrate fossils, including portions of a whale skeleton, have been found in the Imperial formation near Painted Hill. A thick section of the Imperial formation was encountered in the Texas Company Stone 1 "Edom" well, with the top of the Imperial formation over 3,000 feet below the present surface (Quinn and Weismeyer n.d.). These HE• Jul 31 02 02:05p CRM TECH 9097042987 p.28 data further support the theory of a rapidly filling, subsiding basin, making it very doubtful that any pre -Holocene sediments will be encountered within the Coachella Valley proper, especially by normal development grading. The fresh water mollusks, when found in place, indicate that deposition was below the lake surface, and the presence of the mussel (Anodonta sp.) indicates fresh water that is in motion (Schneider 1989). Since this was a large lake, the movement was probably restricted to shallow water within the surf -zone. The presence of fresh water snails suggests the presence of organic debris, such as vegetation like reeds and bull rushes along the shoreline. The shells and shell fragments of Anodonta sp., Gyraulus sp., Physa sp, and Tryonia sp., which are the most common mollusks found in the lake sediments (Quinn 2000b), are light and can be blown about by the same winds that create the shifting sand dunes. When found in a living position, such as paired valves for the Anodonta sp. and clusters of Physa sp. and Tryonia sp., these materials can make good paleo-environmental indicators. However, when they are found as scattered fragments, their paleontological use is questionable at best. To date, no one has found a difference in the lake faunas that inhabited the many separate Holocene lakes that have filled the basin. Since this fauna came from the Colorado River with the water when it filled the basin, all of the lake fillings probably had the same fauna. RECOMMENDATIONS Based on the study results presented above, the proposed project's potential impact: on paleontological resources is determined to be high for Holocene age invertebrate fossils. Therefore, a surface collection of the fresh water mollusk remains should be accomplished, with the specimens identified and curated and placed into a repository with permanent retrievable storage. Monitoring of earth -moving activities for paleontological resources during grading and a program to mitigate impacts to the resources that might be exposed or unearthed during all such excavation is recommended. Such a program should be developed in accordance with the provisions of CEQA as well as with regulations currently implemented by the County of Riverside and the proposed guidelines of the society of Vertebrate Paleontology, and should include, but not be limited to the following, as outlined by Scott (2001): The excavation of areas identified as likely to contain paleontologic resources should be monitored by a qualified paleontological monitor. Monitoring should be restricted to undisturbed Lake Cahuilla beds and any older undisturbed subsurface alluvium, which might be present below the surface. The monitor should be prepared to quickly salvage fossils as they are unearthed to avoid construction delays. The monitor should also remove samples of sediments which are likely to contain the remains of small fossil invertebrates and vertebrates. Collected samples of sediments should be washed to recover small invertebrate and vertebrate fossils. Recovered specimens should be prepared so that they can be identified and permanently preserved. Specimens should be identified and curated and placed into a repository with permanent retrievable storage. 049 ,Jul 31 02 02:06p C TECH 90 42907 p.29 • A report of findings, including an itemized inventory of recovered specimens, should be prepared upon completion of the steps outlined above. The report should include a discussion of the significance of all recovered specimens. The report and inventory, when submitted to the appropriate Lead Agency, would signify completion of the program to mitigate impacts to paleontologic resources. CONCLUSION CEQA Appendix G provides that "a project may be deemed to have a significant effect on the environment if it will ... disrupt or adversely affect a ... paleontological site except as a part of a scientific study." The present study, conducted in compliance with this provision, was designed to identify any significant, non-renewable paleontological resources that may exist within or adjacent to the project area, and to assess the possibility for such resources to be encountered in future excavation and construction activities. Based on the findings from these research procedures, the proposed project's potential impact on paleontological resources is determined to be high for Holocene age invertebrate fossils. Therefore, CRM TECH recommends that grading, grubbing, trenching, excavations, and/or other earth -moving activities in the project area be monitored for paleontological resources, and that a mitigation program be implemented to address potential impacts to any paleontological deposits that are unearthed. 050 'Jul 31 02 02:06p CRM TECH 90 842987 p.30 REFERENCES Dibblee, T.

Previous Work Experience in Paleontology 1969-73 Attended Texaco company -wide seminars designed to acquaint all paleontological laboratories with the capability of one another and the procedures of mutual assistance in solving correlation and paled -environmental reconstruction problems. 1967-1968 Attended Texaco seminars on Carboniferous coral zonation techniques and Carboniferous smaller foraminifera zonation techniques for Alaska and Nevada. 1966-1972, 1974, 1975 Conducted stratigraphic section measuring and field paleontological identification in Alaska for stratigraphic controls. Pursued more detailed fossil identification in the paleontological laboratory to establish closer stratigraphic controls, mainly with Paleozoic and Mesozoic rocks and some Tertiary rocks, including both megafossil and mfcrofossil identification, as well as fossil plant identification. 1965 Conducted stratigraphic section measuring and field paleontological identification in Nevada for stratigraphic controls. Pursued more detailed fossil identification in the paleontological laboratory to establish closer stratigraphic controls, mainly with Paleozoic rocks and some Mesozoic and Tertiary rocks. The Tertiary work included identification of ostracods from the Humboldt and Sheep Pass Formations and vertebrate and plant remains from Miocene alluvial sediments.
