EXECUTIVE SUMMARY •The Planning Commission (Commission) held public hearings on January 25, 2022, and on February 8, 2022, where this project was continued to a date uncertain at the request of the applicant to allow time to address concerns from surrounding residents. •Tentative Tract Map (TTM) 32879 was approved on January 4, 2005, along with Griffin Ranch Specific Plan which included the approval of 303 single-family residential homes (Attachment 1). •The applicant proposes to resubdivide Lots 1 through 20 of TTM 32879 by increasing the number of residential lots from 20 to 37 (Attachment 2). •The map identifies the layout of the subdivision, lot lines, utility and access easements, and common area landscaping. In order to approve the project, the Commission must make findings as it relates to consistency with General Plan and Griffin Ranch Specific Plan and compliance with CEQA (Attachment 3). 38 •Staff prepared an addendum to the Mitigated Negative Declaration (MND) for Griffin Ranch Specific Plan Amendment No. 1, EA2006-577, pursuant to Section 15164 of the California Environmental Quality Act (CEQA) and determined that no substantial changes to the project are proposed that result in new significant environmental effects (Exhibit A). BACKGROUND/ANALYSIS The existing Tract Map 32879 was approved by City Council on January 4, 2005, as a 303 single-family residential lot subdivision part of the Griffin Ranch Specific Plan Area (later amended in 2006 and 2013). These lots were designed for custom designed homes that match the architectural design prevalent in Griffin Ranch. The site is located on the south side of Avenue 54 between Madison and Monroe Streets surrounding the Merv Griffin Estate (Attachment 4). The proposed TTM is a continuation of the development plan for the Griffin Ranch Specific Plan Area. This component of the plan proposes to subdivide 20 existing one-acre (approximately 40,000 square feet) vacant residential lots into 37 half-acre (approximately 20,000 square feet) lots, an increase of 17 additional units. The TTM identifies the utility and access easements, lot lines, and common area landscaping (Attachment 2). The proposed subdivision conforms to the development standards provided in the Griffin Ranch Specific Plan and meets the requirements of the Subdivision Map Act. Common area landscaping is being proposed along Seattle Slew Way, Boulder Ruler Way and Donali Street. The existing planter areas along Avenue 54, which are already landscaped and maintained, will remain. The proposed preliminary landscaping plan plant palette incorporates typical desert compatible species such as Honey Mesquite, Hybrid Fan Palm, Yellow Oleander, etc. Architecture, site, and landscaping design of the homes to be constructed is not part of this TTM application. At the time building permits are applied for these homes, the architecture, site, and landscaping design will be reviewed for its consistency with the design guidelines of the Griffin Ranch Specific Plan. Current access to the tract is via Donali Street, Seattle Slew Way, and Bold Ruler Way and this access shall remain the same. As part of the MND Addendum, a traffic memo was prepared and determined that the addition of 17 units will not have a negative impact on the internal circulation of the project since this tract does not have direct access from any local street. 39 TTM 32879 one-acre (approximately 40,000 square feet) lots were originally intended to act as a buffer between the Griffin Ranch Estates and the Merv Griffin Estate property. The Merv Griffin Estate property has an approved Specific Plan (the Estates at Griffin Lake Specific Plan) for single family residential lots at 10,000 square feet in size. The lot sizes of the surrounding Griffin Ranch Estates range in size from 11,000 and up to 20,000 square feet. The proposed subdivision of 20 lots at 40,000 square feet in size, into 37 lots at 20,000 square feet in size would be more consistent with the size and density of the surrounding Griffin Ranch Estates and Estates at Griffin Lake Specific Plan. A letter was received by Allen Matkins Leck Gamble Mallory & Natsis LLP, attorney on behalf of the applicant, regarding how the Housing Accountability Act and portions of the Housing Crisis Act of 2019 (SB 330) relate to the consideration of this project. The letter has been forwarded to the City Attorney’s office and should there be any questions concerning the contents of the letter, the City Attorney and staff can address them at the meeting.

The Griffin Ranch MND evaluated the impacts associated with the proposed development of a roughly U-shaped master planned community includes 303 residential lots, community clubhouse, streets, retention basins, well sites, internal pedestrian/equestrian trails, and open space areas on approximately 199 acres. The analysis of the Griffin Ranch project identified several mitigation measures to address and mitigate potentially significant impacts to less than significant levels. The adopted Griffin Ranch Specific Plan and MND is included as Appendix A. The previous project is located on 199 acres of disturbed land located south of Avenue 54, east of Madison Street, north of 55th Avenue, and approximately 0.25 miles east of Monroe Street in the City of La Quinta, California. The previous project proposed a General Plan Amendment (GPA 2004-103), a Zone Change (2004-122), a Specific Plan (SP 2004-074), and a Tentative Tract Map (TTM No. 32879). The General Plan Amendment and Zone Change for the previous project was proposed to modify the land use designation on the property from Very Low Density and Very Low Density/Equestrian Overlay, to Low Density Residential. The GPA was also proposed to modify the roadway classification of Madison Street from a Major Arterial to a Primary Arterial. The Specific Plan was proposed to establish the design standards and guidelines for the development of a master planned community. Since 2005, the Griffin Ranch Specific Plan has undergone two Specific Plan Amendments. Specific Plan 2004-074 Amendment No. 1 involved the addition of 90 lots, an enlarged clubhouse, and revised development standards on a separate, roughly square shaped, property located at the southwest corner of Avenue 54 and Monroe Street. This Amendment also included the approval of Tentative Tract Map 34642, to add and subdivide approximately 45 acres into 90 residential lots and other amenity lots, and Environmental Assessment 2006-577, which analyzed the environmental impact of the additional lots. Amendment No. 1 was adopted in April 2007 (Resolution No. 2007-036) and resulted in a total of 393 residential lots on the Griffin Ranch Specific Plan area. SP 2004-074 Amendment No. 2 proposed to reduce the size of the clubhouse in the Griffin Ranch Specific Plan from 21,200 square feet to 10,420 square feet. Amendment No. 2 was adopted in 2013. As previously stated, the Griffin Ranch MND analyzed impacts associated with the proposed development of 303 residential units, opens space uses, and associated improvements on 199 acres of the Griffin Ranch Specific Plan area. A majority of the western portion of the site has now been developed with residential lots, community area, paved driveways, and open space areas. Developed residential lots are scattered throughout the project site. The undeveloped lots onsite have been graded and sprayed with chemical dust suppressant. All roadways within the Griffin Ranch property are paved. The eastern-most portion of the Griffin Ranch Specific Plan area located at the southwest corner of Avenue 54 and Monroe Street (approximately 45 acres added in Amendment No. 1) is undeveloped. The revised project proposes the subdivision of 20 existing 1-acre residential lots into 37 half-acre lots within the Tract Map No. 38083 in the Griffin Ranch Specific Plan area. The 20 lots are currently graded with previously installed utility infrastructure and are centrally located within the Griffin Ranch community, in the “interior” of the U-shaped property and directly adjacent to the Merv Griffin Estate (not a part of the project). The revised project proposes to increase the density 47 City of La Quinta Page 4 Draft Addendum October 2021 of the Tract Map 38083 area; however, a Specific Plan Amendment is not required based on substantial conformance through a Director’s Determination. In accordance with the California Environmental Quality Act (CEQA) and CEQA Guidelines, this addendum addresses the potential environmental impacts associated with the proposed residential community and provides an evaluation of potential environmental impacts in relation to the original project evaluated in the adopted MND. A CEQA MND Addendum does not require analysis of topics that were not required during the time that the original CEQA document was adopted, however for informational purposes, new environmental topics required by the most current CEQA Guidelines have been included. The addendum is an informational document intended to be used in the planning and decision-making process as provided for under Section 15164 of the CEQA Guidelines. The addendum does not recommend approval or denial of the proposed modifications of the previous project. The conclusion of this addendum is that the proposed changes to the project will neither result in new significant impacts nor substantially increase the severity of previously disclosed impacts beyond those already identified in the previously adopted MND. Thus, a subsequent MND is not required. The location of the project site is shown below in Exhibit 1 and 2. 48 N.T.S.

Under CEQA, an addendum to a certified Environmental Impact Report (EIR) or a Negative Declaration (ND) may be prepared if minor technical changes or additions to the proposed project are required or if none of the conditions described in Section 15162 calling for the preparation of a subsequent EIR (or MND) have occurred (CEQA Guidelines Section 15164[b]). An addendum is appropriate if the project changes or modifications do not result in any new significant impacts or a substantial increase in severity of previously identified significant impacts. The addendum need not be circulated for public review (CEQA Guidelines Section 15164[c]); however, an addendum is to be considered along by the decision-making body prior to making a decision on the project (CEQA Guidelines Section 15164[d]). This MND addendum demonstrates that the environmental analysis, impacts, and mitigation requirements identified in the MND remain substantively unchanged by the revised project description detailed herein and supports the findings that the proposed project does not raise any new issues and does not exceed the level of impacts identified in the previous MND. Further, rather than only focusing on the characterization of whether the project is “new” or “old”, the City has also evaluated the previous environmental document to determine if it retains any relevance in light of the proposed changes, and if any major revisions to the document are required due to the involvement of new, previously unstudied significant environmental effects. The subsequent review provisions of CEQA are designed to ensure that an agency proposing changes to a previously approved project explores environmental impacts not considered in the original environmental document. This assumes that some of the environmental impacts of the modified project are considered in the original environmental document, such that the original document retains relevance to the decision-making process. If it is wholly, irrelevant, then it is only logical that the agency starts over from the beginning. The City has determined that project changes will not require major revisions to the initial environmental document. Accordingly, recirculation of the MND for public review is not necessary, pursuant to Section 15164 of the CEQA Guidelines. Therefore, a subsequent Negative Declaration pursuant to Section 15162 of the CEQA Guidelines is not required. To support this decision, the following discussion describes the proposed project modifications and the associated environmental analysis. 51 City of La Quinta Page 8 Draft Addendum October 2021 CHAPTER THREE – SUMMARY OF ORIGINAL PROJECT The previous project includes the Griffin Ranch Specific Plan area on the southeast corner of Avenue 54 and Madison Street. As stated in Chapter One, the City of La Quinta adopted a Specific Plan (SP) and Mitigated Negative Declaration (MND) for the Griffin Ranch Project (Specific Plan No. 2004-074; Resolution 2005-005; Environmental Assessment 2004-526) in January 2005. The SP and MND proposed and analyzed the proposed development of a master planned community includes 303 residential lots, community clubhouse, streets, retention basins, well sites, internal pedestrian/equestrian trails, and open space areas on approximately 199 acres. At the time the MND was written the site was characterized by partially developed land with agricultural and equestrian land uses onsite. Lands in the southeastern quadrant of the site were characterized by vacant desert lands. In its current condition, the entire site has been disturbed from human-related construction activities. The site has also been graded throughout. The western portion of the Griffin Ranch Specific Plan is nearly fully developed with residential homes, community areas, open space areas, and associated improvements. Developed residential homes are found throughout the central and eastern portions of the site (the development pattern primarily extends from the southern and eastern boundaries). However, approximately half of the central and eastern portions of the site is not developed with residential buildings. These areas are, however, graded and sprayed with a dust suppressant agent for dust-control purposes. The entire site includes paved roadways and infrastructure. Access to the site occurs from one point on Madison Street and two points on Avenue 54. The previous project site plan is shown below, in Exhibit 3. 52 N.T.S.MSA CONSULTING, INC.> PLANNING > CIVIL ENGINEERING > LAND SURVEYING34200 Bob Hope Drive, Rancho Mirage, CA 92270760.320.9811 msaconsultinginc.comPREVIOUS PROJECT SITE PLANEXHIBIT3GRIFFIN RANCHCEQA ADDENDUM53 City of La Quinta Page 10 Draft Addendum October 2021 CHAPTER FOUR – PROJECT REVISIONS The revised project proposes Tentative Tract Map Number 38083 (TTM No 38083), which allows for the subdivision of 20 existing 1-acre residential lots into 37 half-acre lots within on approximately 25 acres of the Griffin Ranch Specific Plan area resulting in an additional 17 lots. The 20 lots are currently graded with previously installed utility and road infrastructure and are centrally located within the Griffin Ranch community directly adjacent to the eastern, western and southern boundaries of the Merv Griffin Estate. The revised site plan is indicated in Exhibit 4. The addition of the aforementioned 17 lots would bring the total unit count in Griffin Ranch to 410, which is below the overall allowable number of 478. In addition, the overall project density will marginally increase from 1.6 dwelling units per acre (du/ac) to approximately 1.7 du/ac, which is below the maximum allowed of 2 du/ac. The proposed project is consistent with the current General Plan and Zoning regulations and a Specific Plan Amendment is not required based on substantial conformance through a Director’s Determination. Currently, the SP Land Use Map exhibit has the existing lots under the SP’s 40,000-square-foot lot designation. The appropriate language and graphics have been revised to reflect the proposed subdivision and show these lots under the SP’s 20,000-square-foot designation, which is in character with the community and adjoining 20,000-square-foot lots. No changes are proposed to the existing SP boundary, design guidelines, maximum unit count, maximum density, or development standards. As previously stated, the portion of the site to be revised is currently designated for 40,000- square-foot lots. The 40,000-square-foot designation was established in this area to act as a buffer between the project and the Merv Griffin Estate, which was a private residential estate. However, since then, the Merv Griffin Estate has been entitled under the Griffin Lake Specific Plan for the development of 10,000-square-foot lots, which are directly adjacent to the proposed project. For this reason, the need for a low-density buffer is no longer necessary and the proposed 20,000-square-foot lot designation is in character with the current and future development plans for proposed project and the Griffin Lake Specific Plan. Both the previous and revised projects propose the development of single-family homes on the project site, and the revised project proposes a slight increase in the total number of units. The impact analysis contained herein will focus on whether the revised project would result in any new or more severe impacts not previously identified in the adopted Griffin Ranch Project MND. 54 N.T.S.MSA CONSULTING, INC.> PLANNING > CIVIL ENGINEERING > LAND SURVEYING34200 Bob Hope Drive, Rancho Mirage, CA 92270760.320.9811 msaconsultinginc.comREVISED PROJECT SITE PLANEXHIBIT4GRIFFIN RANCHCEQA ADDENDUM55 City of La Quinta Page 12 Draft Addendum October 2021 CHAPTER FIVE – ENVIRONMENTAL SETTING The Griffin Ranch Specific Plan area, including the revised project site, is located in the City of La Quinta, south of Avenue 54, east of Madison Street, north of Avenue 55, and west of Monroe Street. The previous project analyzed in the MND (Environmental Assessment 2004-526, adopted in 2005) encompassed approximately 199-acres on a roughly U-shaped property. An additional 45 acre roughly square shaped property was included in Amendment No. 1 in 2007. The 2005 MND is analyzed in this Addendum document. The western portion of the Griffin Ranch Specific Plan is nearly fully developed. Developed residential homes are found throughout the central and eastern portions of the site. Approximately half of the central and eastern portions of the site is vacant. Madison Street, west of the site, Avenue 54, north of the site, and Monroe Street, east of the site, are paved. The area surrounding the project site is characterized by developed, residential lots to the west, vacant lots to the south and east, and the Merv Griffin Estate to the north. A golf course residential community is located north of Avenue 54. The revised property occupies approximately 25 acres of the Griffin Ranch SP area and would occur within Tract Map No. 38083 (TTM No. 38083). TTM No. 38083 is located adjacent to the Merv Griffin Estate property. TTM No. 38083 is located in a portion of the north one-half of Section 15, Township 6 South, Range 7 East, San Bernardino Meridian. The project is located within the City of La Quinta’s Low Density Residential (RL) with Equestrian Overlay zone. The existing land use designation for the site is Low Density Residential with Equestrian Overlay. The project does not propose changes to the existing zone and land use designations. The project’s land use is shown in Exhibit 5 and zoning is shown in Exhibit 6.

This addendum provides the project specific environmental review pursuant to CEQA to demonstrate the adequacy of the MND relative to the revised project. As indicated above, the previous MND identified project-related impacts and proposed mitigation measures related to air quality, cultural resources, paleontological resources, noise, transportation. The analysis below discusses the adequacy and applicability of previous mitigation measures to the revised project. In addition, the analysis below addresses whether any new or more severe impacts would result from the project revisions and whether any additional mitigation measures beyond those previously identified in the MND would be required. I. Aesthetics Griffin Ranch Project MND The 2005 MND identified no significant impacts related to aesthetics. According to the MND, the previous project would include single family homes of up to two stories in height. The size of the lots (from 12,000 to 40,000 square feet) and the limitation of single-story development within 150 feet of either Madison Street or Avenue 54 will limit the potential aesthetic impacts associated with the project. The MND also stated that the residential, low intensity character of the project, and the enhanced parkways and trails provided on the perimeter of the site, would serve to limit visual impacts associated with the project site. The MND concluded that the overall impacts associated with the development of the site were expected to be less than significant. The MND also stated that there are no rock outcroppings or other significant resources on the site, therefore impacts associated with scenic resources were expected to be insignificant. Regarding project-related lighting, the MND concluded that construction of the site will increase light generation, compared to the previous light generated from the agricultural uses onsite. Additionally, the City regulates lighting levels and does not allow lighting to spill over into adjacent properties. Further, residential lighting is generally limited, and of low intensity. Therefore, the MND concluded that the impacts of the project related to light would be less that significant, and no mitigation measures were required. Revised Project Similar to the 2005 MND, the revised project would not affect scenic vistas in the area. The surrounding area is largely developed with single family residential lots. The revised project would develop single family residential dwelling units similar in design, scale, and mass to the existing residential structures. Since the revised project proposes residential homes in a neighborhood planned for residential lots, development of the revised project would result in less than significant impacts to scenic vistas, similar to the previous project. Similar to the prior MND, the revised project would be required to comply with design features, landscaping, and lighting requirements established in the Griffin Ranch Specific Plan and City’s zoning ordinance. Additional review from the City’s Planning Commission or architectural review may be required for the revised project to ensure a high-quality design project that is consistent with the Specific Plan and City goals. Therefore, the revised 59 City of La Quinta Page 16 Draft Addendum October 2021 project’s impacts to the visual character of the area would be the same as the previous project, and less than significant. Currently, the residential homes in the Griffin Ranch property consists of low-intensity, downward-oriented lights typical of residential neighborhoods. The lights proposed for the revised project would consist of lighting similar to the existing Griffin Ranch property, and consistent with Section 9.100.150 of the La Quinta Municipal Code. The revised project will not include exterior building materials that would emit significant amounts of glare. Similar to light, the revised project will include similar building materials to the existing residential units in Griffin Ranch for consistency. Therefore, the revised project’s impact to light and glare would result in less than significant impacts, similar to the previous project. As previously determined, rock outcroppings or other significant resources do not exist on the project site. Additionally, the project site is not located in proximity to a state scenic highway, therefore, the revised project would not impact scenic resources adjacent to or within close proximity to state scenic highways. Residential structures located within 150 feet of Avenue 54 would be limited to one-story to reduce the potential aesthetic impacts associated with the project to motorists and pedestrians travelling along these roadways. Therefore, impacts would be less than significant, similar to the MND. The revised project would result in equal impacts to aesthetics compared to the previous project. As concluded in the Griffin Ranch MND and above, both projects would result in no impacts or less than significant impacts to aesthetic resources. The revised project does not propose substantial changes to the project which will require major revisions of the previous MND or substantial changes with respect to the circumstances under which the project is undertaken that would require major revisions to the previous MND. Additionally, new substantially important information that was not included in the MND is not proposed in the revised project. Therefore, following Section 15162 of the CEQA Guidelines, the revised project is not required to prepare a subsequent MND. II. Agricultural Resources Griffin Ranch Project MND The MND concluded that the previous project would result in no significant impacts related to agricultural and forest/timberland resources. According to the MND, the Griffin Ranch site is located adjacent to single family residential developments and golf course uses. Per the MND, approximately 40 acres of the Griffin Ranch SP area, as well as lands to the east, were used for agriculture. However, the MND stated that the Griffin Ranch area is located in a rapidly urbanizing area of the City and is not under Williamson Act contract. Therefore, the MND concluded that the development of Griffin Ranch (resulting in the loss of approximately 40 acres of agricultural land) would not be significant. It was determined that the previous project would not prevent the continued use in agriculture of lands to the east. However, the City’s General Plan land use designation for the Griffin Ranch area and surrounding properties includes residential developments of varying sizes. Therefore, the MND concluded that the project would not result in impacts to agricultural resources. Revised Project 60 City of La Quinta Page 17 Draft Addendum October 2021 The revised project would not change the existing land use or zoning of the property. The project site does not include any active agricultural uses or agricultural resources, and is not adjacent to such uses, and is not zoned or designated for agricultural uses. The Griffin Ranch SP area has been partially developed with residential units, while most of the vacant lots within the SP area have been disturbed and graded. Thus, the revised project would not result in impacts to agricultural resources, similar to the MND. The revised project would result in equal impacts to agricultural resources compared to the previous project. As concluded in the Griffin Ranch MND and above, both projects would result in no impacts to agriculture. The revised project does not propose substantial changes to the project which will require major revisions of the previous MND or substantial changes with respect to the circumstances under which the project is undertaken that would require major revisions to the previous MND. Additionally, new substantially important information that was not included in the MND is not proposed in the revised project. Therefore, following Section 15162 of the CEQA Guidelines, the revised project is not required to prepare a subsequent MND. III. Air Quality Griffin Ranch Project MND For reference purposes, the Griffin Ranch MND air quality analysis based its findings primarily on the “Griffin Ranch Specific Plan and Vesting Tentative Map 32879 Air Quality and Noise Impact Study”, completed in September of 2004. Under this project scope, the prior MND found that the residential project would result in no impacts regarding the exposure of sensitive receptors to substantial pollutant concentrations and regarding objectionable odors affecting a substantial number of people. The prior MND also determined that the project would result in less than significant impacts regarding conflicts with the applicable air quality plan and regarding a cumulatively considerable net increase of any criteria pollutant for which the project region is non-attainment. It was also determined that project would not exceed any SCAQMD thresholds of significance for operational emissions. However, the short-term grading and construction activities were expected to potentially exceed the emissions thresholds for reactive organic gases (ROG) and nitrogen oxides (NOx). As a result, construction-related mitigation was formulated to adequately reduce ROG and NOx emissions levels during construction, including the phasing of grading activity and compliance with the applicable SCAMQD rules pertaining to dust control and volatile organic compound limits in architectural coatings. Such mitigation was deemed to result in less than significant impacts. Following project and MND approval, clearing and grading operations were completed in 2005. Perimeter walls and on-site infrastructure were also initially completed, while home construction continued to occur in phases. Therefore, the prior mitigation referenced in the adopted MND is deemed complete. Revised Project Since the prior environmental review, the project setting has not incurred any substantial change in circumstances deemed inconsistent with the project’s planned residential uses taking place in multiple construction phases. The current analysis applies to an area of approximately area of 24.93 acres corresponding to Tentative Tract Map No. 38083 (TTM 61 City of La Quinta Page 18 Draft Addendum October 2021 No. 38083), which is located within Tract Map No. 32879. In its current condition, the TTM No. 38083 area consists of rough-graded lots with installed back-bone utilities and partially constructed private streets. The site is partially surrounded by solid walls corresponding to neighboring constructed homes within Griffin Ranch and the perimeter wall associated with Merv Griffin Estate (not a part). The current map conditions allocate 20 single-family residential lots. Since the prior MND, the regulatory framework and air quality standards have undergone updates, including those reflected in the adopted Air Quality Management Plan (2016 AQMP) currently applicable to the entire SCAMQD jurisdiction. However, the SCAQMD construction and operational thresholds, to which the prior project was compared, have not changed. The project region is continuing to implement SIPs toward establishing attainment for PM10 (particulate matter with an aerodynamic diameter of 10 microns or less) and Ozone. Those attainment updates are summarized as follows: Regarding PM10, on February 25, 2010, the ARB approved the 2010 Coachella Valley PM10 Maintenance Plan and transmitted it to the U.S. EPA for approval. With the recent data being collected at the Coachella Valley monitoring stations, consideration of high-wind exceptional events, and submittal of a PM10 Re-designation Request and Maintenance Plan, a re- designation to attainment status of the PM10 NAAQS is deemed feasible in the near future according to the 2016 AQMP. As a standard requirement, the remaining construction activities for project buildout would be subject to SCAMQD Rules 403 and 403.1, as well as La Quinta’s Fugitive Dust Control requirements (Chapter 6.16) aimed at addressing the PM10 concerns for the region. The required measures are designed to prevent sediment track-out onto public roads, prevent visible dust emissions from exceeding a 20-percent opacity, and prevent visible dust emissions from extending more than 100 feet (vertically or horizontally from the origin of a source) or crossing any property line. The proposed project would not be precluded from the citywide dust control requirements during construction and therefore would continue to work toward preventing emissions impacts to nearby residential uses through the proper project site screening, track-out controls, and soil stabilization. After project completion, permanent site stabilization through residential construction would eliminate the potential source of fugitive dust. Regarding ozone, SCAQMD is continuing to implement an updated strategy to comply with the ozone standard (1997 8-hour standard), for which there is a target attainment date of June 15, 2024. SCAQMD has acknowledged that the largest ozone contributors to the Coachella Valley are not sources within the region, but rather the ozone and ozone precursors transported to the Coachella Valley from the upwind South Coast Air Basin (SCAB). SCAQMD deems that local sources of air pollution generated in the Coachella Valley have a limited impact on ozone levels compared to the transported sources generated in SCAB. The current analysis described below will calculate potential ozone precursor emissions to compare against the established standards. TTM No. 38083 proposes to subdivide 20 existing one-acre residential lots into 37 half-acre lots through the Tentative Tract Map process. The project footprint of approximately 24.93 acres occurs completely within the Griffin Ranch residential community. To perform and support the current analysis, the most current version of California Emissions Estimator Model (CalEEMod Version 2020.4.0) was used to calculate the project-related construction and operational emissions of criteria air pollutants and greenhouse gases. CalEEMod was developed for the California Air Pollution Control Officers Association (CAPCOA) in 62 City of La Quinta Page 19 Draft Addendum October 2021 collaboration with the California Air Districts (including SCAMQD) as a statewide land use emissions computer model. For comparative analysis, the software model was run respectively for construction and operation of the currently mapped condition of 20 residential lots and for the proposed condition of 37 lots in the same area and setting. The model input also assumed construction activities associated with buildout of the private streets and designation of open space areas per the TTM. The emissions calculations for both development scenarios are compared against the most current SCAMQD Air Quality Significance Thresholds below. Table III-1 Short Term Air Pollutant Emissions Associated with Construction 20 Lots and Associated Improvements (Pounds/Day) ROG/VOC NOx CO SO2 PM10 PM2.5 Max Emissions Resulting from Site Preparation, Grading, Building Construction, Paving, and Architectural Coating 14.7793 38.8842 29.6608 0.0636 8.2541 4.8668 SCAQMD Threshold 75 100 550 150 150 55 Threshold Exceeded No No No No No No Note: CalEEMod does not directly calculate ozone (O3) emissions. Instead, the emissions associated with ozone precursors are calculated. VOC and ROGs are summed in the CalEEMod report under the header ROG. The PM10 and PM2.5 emissions are based on the CalEEMod mitigated results due to the local standard requirement to implement SCAQMD Rule 403 and 403.1 to control fugitive dust. Table III-2 Short Term Air Pollutant Emissions Associated with Construction 37 Lots and Associated Improvements (Pounds/Day) ROG/VOC NOx CO SO2 PM10 PM2.5 Max Emissions Resulting from Site Preparation, Grading, Building Construction, Paving, and Architectural Coating 24.3560 38.8842 29.6608 0.0636 8.1755 4.8475 SCAQMD Threshold 75 100 550 150 150 55 Threshold Exceeded No No No No No No Note: CalEEMod does not directly calculate ozone (O3) emissions. Instead, the emissions associated with ozone precursors are calculated. VOC and ROGs are summed in the CalEEMod report under the header ROG. The PM10 and PM2.5 emissions are based on the CalEEMod mitigated results due to the local standard requirement to implement SCAQMD Rule 403 and 403.1 to control fugitive dust. As demonstrated in tables III-1 and III-2 above for the 20- and 37-lot scenario, short-term construction emission levels resulting from site preparation, grading, building construction, paving and architectural coating are not expected to exceed the reginal thresholds of significance established by SCAQMD for criteria air pollutants, including NOx and ROG/VOC as the ozone pre-cursors. Compliance with SCAMQD Rule 403/403.1 and Municipal Code Chapter 6.16 is factored in to calculate the PM10 and PM2.5 emissions. Implementation of the proposed 37-lot scenario would result in relatively higher short-term emission levels compared to the 20-lot scenario, but neither would reach or exceed any of the established thresholds. 63 City of La Quinta Page 20 Draft Addendum October 2021 Table III-3 Long Term Operational Air Pollutant Emissions Associated With Development of the Project (Unmitigated) (Pounds/Day) Emission Source ROG/VOC NOx CO SO2 PM10 PM2.5 Total Area Sources, Energy Use, Mobile Sources 2.9813 1.0303 8.8553 0.0188 1.3878 0.7262 SCAQMD Threshold 75 100 550 150 150 55 Threshold Exceeded No No No No No No Note: CalEEMod does not directly calculate ozone (O3) emissions. Instead, the emissions associated with ozone precursors are calculated. VOC and ROGs are summed in the CalEEMod report under the header ROG. Table III-4 Long Term Operational Air Pollutant Emissions Associated With Development of the Project (Unmitigated) (Pounds/Day) Emission Source ROG/VOC NOx CO SO2 PM10 PM2.5 Total Area Sources, Energy Use, Mobile Sources 5.4296 1.9061 16.3818 0.0347 2.5675 1.3434 SCAQMD Threshold 75 100 550 150 150 55 Threshold Exceeded No No No No No No Note: CalEEMod does not directly calculate ozone (O3) emissions. Instead, the emissions associated with ozone precursors are calculated. VOC and ROGs are summed in the CalEEMod report under the header ROG. As demonstrated in tables III-3 and III-4 above for the 20- and 37-lot scenario, long-term operational air pollutant emissions that would occur during the life of the project would not exceed any of the SCAQMD air quality thresholds. Operation of proposed 37-lot scenario would result in higher short-term emission levels compared to the 20-lot scenario, but neither would reach or exceed any of the thresholds. In summary, due to the compliant emission levels, the proposed project would not interfere with the City or region’s ability to comply with the most current air quality plans including the 2016 AQMP, CVSIP for PM10, and the ozone level attainment efforts. Therefore, the revised project would result in less than significant impacts to the region’s air quality standards, similar to the previous project. Moreover, the project’s short-term construction and long-term operational emissions would not exceed the established thresholds for criteria air pollutant emissions; therefore, the revised project will result in less than significant impacts to criteria air pollutant emissions. Pertaining to the obstruction of an applicable air quality plan, less than significant impacts are anticipated, similar to the previous project. Similar to the previous project, the revised project would result in no impacts regarding the generation of odors, since it proposes the development of residential lots. 64 City of La Quinta Page 21 Draft Addendum October 2021 The revised project does not propose substantial changes to the project which will require major revisions of the previous MND or substantial changes with respect to the circumstances under which the project is undertaken that would require major revisions to the previous MND. Additionally, new substantially important information that was not included in the MND is not proposed in the revised project. Therefore, following Section 15162 of the CEQA Guidelines, the revised project is not required to prepare a subsequent MND. IV. Biological Resources Griffin Ranch Project MND The MND evaluated potential biological resource impacts associated with the development of the 199-acre project site. James W. Cornett, Ecological Consultants conducted a search of available literature and conducted a general biological survey of the project property to identify special status plants, wildlife, and habitats known to occur in the vicinity of the project site. Records, collections and/or staff of the University of California at Riverside Herbarium, the Living Desert, the Boyd Deep Canyon Desert Research Station, and Natural Diversity Database were consulted. The MND states the biological study analyzed the entire site, with a particular focus on the 60-acres located in the northwestern and southeastern corners of the site which was undisturbed vacant land. No listed species were found on the project site and surveys for the desert tortoise and burrowing owl were negative. The prior analysis concludes that that no riparian habitat or wetland habitat was identified on the project site and that the site does not occur within the boundary of the Coachella Valley Fringed-toed lizard. Therefore, impacts to biological resources were found to be less than significant. Revised Project Similar to the MND, the revised project would result in less than significant impacts associated with sensitive habitat, riparian habitat, or other sensitive natural community as none of these resources were identified on the project site. The site has been heavily impacted by grading and development and surrounded by single family residential homes. Additionally, the 2004 biological report also found no impacts to any native resident or migratory fish or wildlife species, or with established native resident or migratory wildlife corridors or nursery sites. No conflicts with local policies or ordinances protecting biological resources such as a tree preservation policy or ordinance would occur under the revised project. Less than significant impacts are anticipated. The revised project would result in equal impacts to biological resources compared to the previous project. As concluded in the Griffin Ranch MND and above, both projects would result in no impacts or less than significant impacts to biological resources. The revised project does not propose substantial changes to the project which will require major revisions of the previous MND or substantial changes with respect to the circumstances under which the project is undertaken that would require major revisions to the previous MND. Additionally, new substantially important information that was not included in the MND is not proposed in the revised project. Therefore, following Section 15162 of the CEQA Guidelines, the revised project is not required to prepare a subsequent MND. 65 City of La Quinta Page 22 Draft Addendum October 2021 V. Cultural and Tribal Cultural Resources Griffin Ranch Project MND The MND evaluated potential cultural resource impacts associated with the development of the 199-acre project site. Phase I and Phase II cultural resources studied were completed for the proposed project. The studies identified and recorded six potentially significant cultural resource sites within the project area. These sites consisted of ceramic scatters and groundstone fragments. The archaeologist concluded that the six sites potential significance has been mitigated by the collection of materials, the laboratory analysis performed. The site lies within the City’s General Plan map boundary for ancient Lake Cahuilla and mitigation has been adopted to assure potential impacts are mitigated. The following mitigation was established for the project: 1. Local tribes shall be contacted in writing for comments prior to issuance of the first grubbing, earth moving or grading permit. The applicant shall provide the Community Development Department with all written responses received within one month prior to issuance of any grading permit. One Native American monitor shall be required should the tribes request it. 2. The site shall be monitored on and off-site trenching and rough grading by qualified archaeological and paleontological monitors. Proof of retention of monitors shall be submitted to the City prior to issuance of the first earth-moving or clearing permit. 3. The final report on monitoring shall be submitted to the Community Development Department prior to the issuance of the first production home permit for the project. 4. Collected archaeological resources shall be properly packaged for long term curation, in polyethylene self-seal bags, vials, or film cans as appropriate, all within acid free, standard size, comprehensively labeled archive boxes and delivered to the City prior to issuance of first Certificate of Occupancy for the property. Materials shall be accompanied by descriptive catalogue, field notes and records, primary research data, and the original graphics. 5. Results of the final artifact analysis and site interpretation shall be submitted to the Community Development Department for review by the Historic Preservation Commission prior to issuance of the first grading, clearing or grubbing permit. 6. A paleontological resources survey shall be conducted on the project site prior to the initiation of ant ground disturbance. The study shall be conducted in conformance with the City’s standard such a study and shall be submitted for review and approval. The MND concludes that potential impacts to cultural, tribal cultural, and paleontological resources have been mitigated to a less than significant. Revised Project The revised project proposes a Tentative Tract Map to allow for the subdivision of 20 existing 1-acre lots into 37 half acre lots within the same footprint. The 20 lots are currently graded with improvements. The revised project would not require construction beyond what was anticipated in the MND. While the overall lot count is proposed to change, no additional grading beyond what was anticipated in the MND would occur. Similar to the MND, the revised project would result in no impacts to historic resources, as defined in Section 15064.5 of the CEQA Guidelines. This includes any object, structure, site, area, place, record, or manuscript which a lead agency determines to be historically significant. 66 City of La Quinta Page 23 Draft Addendum October 2021 As discussed in the MND, there is the potential for grading to impact significant archaeological resources. Therefore, if grading or trenching of the revised project exceeds the depth of the previous onsite rough grading activities, the revised project would be required to implement mitigation measure 1 through 6 as required in the MND. This would ensure impacts to cultural, tribal cultural, and paleontological resources would be less than significant with mitigation, the same that was identified in the MND. The revised project would result in equal impacts to cultural and tribal cultural resources compared to the previous project. As concluded in the Griffin Ranch MND and above, both projects would result in less than significant impacts with mitigation to cultural and tribal cultural resources. The revised project does not propose substantial changes to the project which will require major revisions of the previous MND or substantial changes with respect to the circumstances under which the project is undertaken that would require major revisions to the previous MND. Additionally, new substantially important information that was not included in the MND is not proposed in the revised project. Therefore, following Section 15162 of the CEQA Guidelines, the revised project is not required to prepare a subsequent MND. VI. Energy Resources Griffin Ranch Project MND The Griffin Ranch Project MND was prepared prior to the requirement of energy resources analysis in the CEQA Appendix G Checklist. As a result, this topic of environmental review was not a part of the adopted project and is included herein for informational purposes only. Revised Project Since the prior MND adoption, the topic of energy resources has been added to the CEQA Appendix G Checklist with the respective thresholds of significance primarily centered around the quantification of project-related energy consumption related to the wasteful use of energy and the project’s compliance with local, regional and state policies regarding energy. As a result, this supplemental analysis also focuses on the energy consumption quantities and the project’s compliance with relevant policies and regulations. The revised project would not require grading or construction beyond the project area analyzed in the MND. The revised project proposes the subdivision of 20, 1-acre lots, to 37 half-acre lots on approximately 25 acres. Currently, the site is graded and includes infrastructure developed previously. Although the project proposes to increase the number of lots on the approximately 25-acre area, no additional grading beyond what as anticipated in the MND would occur. The number of dwelling units increased by 17 (20 to 37 dwelling units), which is compliant with the existing land use and zoning designations. The operation of the site would still consist of activities associated with residential communities. Associated improvements also include paved drive aisles and landscaping. To perform and support the current analysis, CalEEMod Version 2020.4.0 was used to calculate the project-related construction and operational energy consumption. The project is expected to consume energy in the form of electricity, natural gas, and petroleum during construction and operation. The software model was run respectively for construction and operation of the currently mapped condition of 20 residential lots and for the proposed condition of 37 lots in the same area and setting. The model input also assumed construction 67 City of La Quinta Page 24 Draft Addendum October 2021 activities associated with buildout of the private streets and designation of open space areas per the TTM. CalEEMod emission reports for the 20-lot project is included as Appendix B, C, and D; while Appendix D, F and G show the CalEEMod emission reports for the revised 37- lot project. Construction It can be concluded that electricity consumed during construction of the project would be temporary and negligible, while natural gas would not be consumed during construction of the project. Most energy used during construction would be from petroleum consumption during the use of heavy construction equipment and construction worker commute. As previously stated, CalEEMod was utilized to determine how much energy consumption would occur from the previous project, 20, 1-acre lots, and 37 half-acre lots. Energy consumption from the construction of the 20-lot project would result in 14,851.5 gallons of gasoline and 66,469.6 gallons of diesel fuel during the project’s construction. In total, the 20-lot project would consume approximately 81,321.1 gallons of petroleum during construction. This is indicated in Table VI-1. Table VI-1 Previous Project Construction Petroleum Consumption Petroleum Units Previous Project (20 lots) Gasoline Gallons 14,851.5 Diesel Gallons 66,469.6 Total Petroleum Consumption 81,321.1 The revised project proposes to increase the lots on the approximately 25-acre site by 17 lots, for a total of 37 lots. The CalEEMod calculations determined that the project is estimated to consume approximately 15,666.4 gallons of gasoline and 66,729 gallons of diesel fuel during project construction. In total, the revised project would consume approximate 82,395.4 gallons of petroleum during construction. This is approximately 1,074.3 gallons more than the previously 20-lot project. This is indicated in the table below. Table VI-2 Construction Petroleum Consumption Petroleum Units Previous Project (20 lots) Revised Project (37 Lots) Gasoline Gallons 14,851.5 15,666.4 Diesel Gallons 66,469.6 66,729 Total Gallons 81,321.1 82,395.4 Difference (total) 1,074.3 Gallons The construction equipment utilized for development of the proposed project would include Tier 3 engines or higher, and will include newer off-road equipment units. Therefore, the revised project would result in less than significant impacts to energy consumption during construction of the project. Operation The operational energy consumption, via electricity, natural gas and petroleum for the project 68 City of La Quinta Page 25 Draft Addendum October 2021 site is indicated in the table below. The revised project is proposed to consume approximately 294,692 kWh of electricity per year, which is approximately 135,399 kWh more electricity consumed than the previous project due to the increased unit number. However, the La Quinta General Plan Environmental Impact Report (LQGP EIR) predicts that buildout of residential uses in the General Plan, including the proposed project site, will result in electrical consumption of 530,867,194 kWh/year. The revised 37-lot project is anticipated to consume approximately 294,692 kWh/year, which is approximately 0.055 percent of the City’s electrical consumption at total build-out. According to the LQGP EIR, at General Plan build-out, residential units will use approximately 953,444,843.9 kBTU of natural gas per year. The 37-lot project is anticipated to consume approximately 1,046,620 kBTU/year, which is approximately 0.11 percent of the City’s natural gas consumption at total build-out. Finally, California consumes approximately 26 billion gallons of petroleum per year. The 37-lot project is anticipated to consume approximately 29,199.7 gallons of petroleum per year, which is approximately 0.0001 percent of the California’s estimated consumption of petroleum a year. Therefore, operation of the revised project is not anticipated to use excessive amounts of electricity, natural gas, and petroleum, and impacts were expected to be less than significant. In this context, the revised project would not result in the wasteful, inefficient, or unnecessary consumption of energy resources during construction or operation of the project, similar to the previous project. Table VI-3 Operational Energy Consumption Energy Previous Project (20 lots) Revised Project (37 Lots) Electricity (kWh) 159,293 294,692 Natural Gas (kBTU/yr) 565,739 1,046,620 Gasoline (gallons) 14,739.9 27,268.9 Diesel (gallons) 1,043.7 1,930.8 The revised project will comply with state-implemented building standards such as those outlined in Title 20 and Title 24 of the California Code of Regulations. Energy efficient appliances will be utilized during project operation. Project-related energy consumption and VMTs created by the project are not anticipated to be substantial. Construction activities would require the use of equipment that would be more energy intensive that is used for comparable activities. However, construction equipment will comply with the Tier 3 program engines or higher, therefore would be newer off-road equipment units. Therefore, the revised project would not conflict or obstruct a state or local plan for renewable energy or energy efficiency. The revised project would result in more energy consumed compared to the 20 lots approved and analyzed in the previous project, due to the increase of 17 additional lots. However, as concluded above, both the previous project and revised project would result in less than significant impacts to energy resources. Major revisions to the MND are not required due to changes to the project as there have been no substantial changes in circumstances requiring major MND revisions; and there is no new information showing greater significant effects than disclosed in the previous MND. VII. Geology and Soils Griffin Ranch Project MND 69 City of La Quinta Page 26 Draft Addendum October 2021 According to the MND, a project-specific geotechnical analysis was completed for the project. The geotechnical anlaysis determined that the project site is not located within an Alquist- Priolo earthquake study zone. The analysis also determined that development of a residential project on the property is feasible, with the implementation of standards already in place at the City. The MND states that groundwater was not found at a depth of up to 50 feet, based on boring tests provided in the geotechnical analysis. Therefore, the MND stated that the site is not subject to liquefaction. Additionally, the site is not located adjacent to rock outcroppings or hillsides, and is therefore, not subject to landslides or rockfalls. The site is not located on expansive soils, and the Griffin Ranch SP project proposed to connect to Coachella Valley’s Water District’s (CVWD) sewer infrastructure and therefore would not require septic tanks. With the foregoing, the MND concluded that impacts regarding geology and soils at the site would be less than significant. Revised Project The revised project would not require grading or construction beyond what was anticipated in the MND. As such, no new or increased impacts related to geology and soils would occur. Compliance with the most current State building codes and regulations would ensure grading and development of the site would reduce the impacts associated with geology and soils to less than significant, as concluded in the MND. The project shall comply with the most current seismic design coefficients and ground motion parameters and all applicable provisions of the California Building Code (CBC). Additionally, the proposed buildings shall be required to be constructed in a manner that reduced the risk of seismic hazards (Title 24, California Code of Regulations). Remedial grading and construction would reduce exposure of people or structures to adverse effects of seismic hazards to the greatest extent possible. All grading and construction plans will be reviewed by the City for approval. This will ensure that the foundation soils can support the proposed project. The revised project would result in equal impacts to seismic-related hazards. However, as concluded in the Griffin Ranch MND and above, project-related impacts to seismic-related hazards would be less than significant. Additionally, the implementation of a Fugitive Dust Control Plan (as required by Chapter 6.16 in the City’s Municipal Code) and a Storm Water Pollution Prevention Plan (SWPPP) during construction activities to reduce impacts of soil erosion at the site. Grading plans will be developed in compliance with the City’s standards and will be reviewed by the City. The revised project would result in similar impacts regarding project-related erosion compared to the previous project since they both propose development on the site. However, with the compliance of City standards, the revised project would ensure erosion at the site would be less than significant. As determined in the Griffin Ranch MND, the project is not located on expansive soils, and the site will connect to CVWD sewer systems; therefore, septic tanks are not required. The revised project would result in similar impacts compared to the previous project. Both the previous project and revised project would result in no impacts. Overall, the revised project would result in similar impacts to geology and soils compared to the previous project. As concluded in the Griffin Ranch MND and above, both projects would result in no impacts or less than significant impacts. The revised project does not propose substantial changes to the project which will require major revisions of the previous MND or 70 City of La Quinta Page 27 Draft Addendum October 2021 substantial changes with respect to the circumstances under which the project is undertaken that would require major revisions to the previous MND. Additionally, new substantially important information that was not included in the MND is not proposed in the revised project. Therefore, following Section 15162 of the CEQA Guidelines, the revised project is not required to prepare a subsequent MND. VIII. Greenhouse Gas Emissions Griffin Ranch Project MND The previous MND was prepared prior to the requirement of greenhouse gas (GHG) emissions analysis in the CEQA Appendix G Checklist. As a result, this topic of environmental review was not a part of the adopted project and is included herein for information purposes only. Revised Project Since the prior MND adoption, the topic of GHG emissions has been added to the CEQA Appendix G Checklist with the respective thresholds of significance primarily centered around the quantification of emission for comparison against the regionally applicable numeric standards. As a result, this supplemental analysis also focuses on the emissions quantities. To perform and support the current analysis, CalEEMod Version 2020.4.0 was used to calculate the project-related construction and operational GHG emissions. The software model was run respectively for construction and operation of the currently mapped condition of 20 residential lots and for the proposed condition of 37 lots in the same area and setting. The model input also assumed construction activities associated with buildout of the private streets and designation of open space areas per the TTM. CalEEMod emission reports for the 20-lot project is included as Appendix B, C, and D; while Appendix D, F and G show the CalEEMod emission reports for the revised 37-lot project. The currently applicable GHG thresholds for local lead agency consideration are referenced from the SCAQMD Working Group Threshold supporting documentation, which establishes an interim tiered approach. Under this guidance, a screening threshold of 3,000 metric tons of carbon dioxide equivalent (MTCO2e) per year has been an acceptable approach for this project. The GHG emissions estimates resulting from CalEEMod are displayed below in Table VIII-1. Table VIII-1 Total Project Greenhouse Gas Emissions Associated with 20 Lots and Associated Improvements Emission Source Emissions Metric Tons of Carbon Dioxide Equivalent (MTCO2e) per year Total MTCO2e Annual Construction Emissions Amortized Over 30 Years 15.6645 71 City of La Quinta Page 28 Draft Addendum October 2021 Area, Energy, Mobile Sources, Waste, and Water Usage 215.8178 Total MTCO2e (All Sources) 231.4823 Screening Threshold 3,000 MTCO2e Threshold Exceeded? NO Table VIII-2 Total Project Greenhouse Gas Emissions Associated with 37 Lots and Associated Improvements Emission Source Emissions Metric Tons of Carbon Dioxide Equivalent (MTCO2e) per year Total MTCO2e Annual Construction Emissions Amortized Over 30 Years 15.8405 Area, Energy, Mobile Sources, Waste, and Water Usage 399.4277 Total MTCO2e (All Sources) 415.2682 Screening Threshold 3,000 MTCO2e Threshold Exceeded? NO As summarized above, development of 20 lots, as currently mapped, would result in a total of 231.4823 MTCO2e per year from construction, area, energy, mobile sources, waste, and water usage sources. By comparison, the proposed development of 37 lots would result in 415.2682 MTCO2e per year from the same sources. Although the operation of 37 lots would result in higher GHG emissions, these would still occur considerably below the established thresholds. As a result, neither the 20- or 37-lot development scenario would result in potentially significant impacts. Having been evaluated against the regionally accepted thresholds, which are part of the State’s regulations aimed at addressing climate change, the project is not expected to interfere with the plans, policies, or regulations adopted for the purpose of reducing the emissions of greenhouse gases. Less than significant impacts are anticipated. IX. Hazards and Hazardous Materials Griffin Ranch Project MND According to the MND, the Griffin Ranch project would not create a significant impact on or from hazardous materials, since it is proposing single family homes. The City’s solid waste contractor implements household hazardous waste programs which assure that such materials are disposed of in a safe manner. Therefore, the MND concluded that the project would not result in impacts. Revised Project 72 City of La Quinta Page 29 Draft Addendum October 2021 The revised project would not require grading or construction beyond what was anticipated in the MND and would not change the allowable uses on the property from the previous project. As such, no new or more impacts related to hazards or hazardous materials would occur. As discussed in the MND, hazardous materials are not typically associated with residential land uses. Minor cleaning products and the occasional use of pesticides and herbicides for landscape maintenance would be the extent of materials used. Therefore, similar to the MND, the revised project would result in similar impacts compared to the previous project. Both projects would not result in significant impacts. Construction of the project was expected to involve the temporary management and use of potentially hazardous substances and petroleum products. The nature and quantities of these products would be limited to what is necessary to carry out construction of the project. Some of these materials would be transported to the site periodically by vehicle and would be stored in designated controlled areas on a short-term basis. When handled properly by trained individuals and consistent with the manufacturer’s instructions and industry standards, the risk involved with handling these materials would be considerably reduced. To prevent a threat to the environment during construction, the management of potentially hazardous materials and other potential pollutant sources would be regulated through the implementation of control measures required in the Storm Water Pollution Prevention Plan (SWPPP) for the project. The SWPPP requires a list of potential pollutant sources and the identification of construction areas where additional control measures are necessary to prevent pollutants from being discharged. The measures outlined in SWPPP documents require physical improvements and procedures to prevent impacts of pollutants and hazardous materials to workers and the environment during construction. Compliance with industry and manufacturer standards regarding the handling, use, delivery, and storage of hazardous materials would ensure impacts of accidental release or the handling of hazardous materials during construction and operation of the site would be less than significant. Development of the revised project would result in similar impacts to the use of hazardous materials compared to the previous project since they both proposed the development of residential units. With the implementation of the SWPPP, impacts would not be significant. In addition, the project site is not located within one-quarter mile of a school. Therefore, impacts would be less than significant. The project is not within an airport land use plan, or within two miles of an airport or airstrip. Therefore, the revised project would result in similar impacts to schools or airports compared to the previous project. As determined in the Griffin Ranch MND and above, both projects would result in no impacts. Implementation of the revised project would not physically interfere with an adopted emergency response plan or emergency evacuation plan. The revised project occurs within a partially developed residential community. Access to the site includes paved roads with fire truck accessible drive aisles to ensure adequate emergency response access on-site. The proposed design would be subject to a standard review process by the Riverside County Fire Department to ensure that the site-specific emergency access, water pressure, and other pertinent criteria are met by the revised project. Impacts will not be significant. The revised project would result in similar impacts regarding emergency response and evacuation plans compared to the previous project. The project is located outside of areas designed as Very High/High/Moderate Fire Hazard 73 City of La Quinta Page 30 Draft Addendum October 2021 Severity Zone (FHSZ) for State and Federal Responsibility Areas, and Very High FHSZ for Local Responsibility Areas. The project is not located near wildlands and impacts were determined to be less than significant. The revised project will not result in additional grading or construction beyond the boundaries of the property analyzed in the MND. Therefore, impacts of wildfires would not be significant, similar to the MND. Both projects would result in similar impacts to exposing people or structures to a risk involving wildland fires. No impacts would occur due to the project’s location outside of a Very High FHSZ. Overall, the revised project would result in equal impacts of hazards and hazardous materials compared to the previous project. As concluded in the Griffin Ranch MND and above, both projects would result in no impacts or less than significant impacts.. The revised project does not propose substantial changes to the project which will require major revisions of the previous MND or substantial changes with respect to the circumstances under which the project is undertaken that would require major revisions to the previous MND. Additionally, new substantially important information that was not included in the MND is not proposed in the revised project. Therefore, following Section 15162 of the CEQA Guidelines, the revised project is not required to prepare a subsequent MND. X. Hydrology and Water Quality Griffin Ranch Project MND The Griffin Ranch MND evaluated the residential project against the hydrology and water quality thresholds applicable under CEQA at the time of preparation. The prior MND analysis cited various regulatory requirements and project-specific engineering design approvals necessary to adhere to the local hydrology and surface water quality standards, as well as mandates under the National Pollution Discharge Elimination System (NPDES) framework (Section 402 of the Clean Water Act). Specifically, the prior MND determined that the project proponent would be required to obtain coverage under the applicable NPDES permits and comply with the City’s requirement to retain stormwater runoff from the controlling 100-year storm event on-site. The site design included a private storm drain system with dual use open space and retention basins designed to accept infiltrate project runoff from the 100-year storm event and in doing so, also provide flood protection to the residential structures. Such storm drain system would be privately funded and maintained. Therefore, the prior MND found that the project would not generate runoff which would exceed the capacity of existing or planned stormwater drainage systems or provide substantial sources of pollution. The prior MND also determined that the project would not place housing or structures within a 100-year flood hazard area and would not impede or redirect flood flows. These findings of no significant impact were supported by the proposed storm drain design with retention basins. The prior MND determined less than significant impacts regarding water quality standards or waste discharge requirements, groundwater supplies, existing drainage patterns, erosion, siltation, and flooding conditions. These findings of less than significant impacts were also supported by the evaluation of the proposed storm drain design aimed at complying with the hydrology and water quality standards, as well as the water efficiency measures across the project. Revised Project 74 City of La Quinta Page 31 Draft Addendum October 2021 Since the prior environmental review, the project setting has not incurred any substantial change in circumstances inconsistent with the project’s phased residential development and the associated storm drain infrastructure. Storm drain facilities are operational and are maintained by the homeowner’s association. The Griffin Ranch community is divided into two on-site hydrologic drainage areas, each served by a retention system (Basin 1 and 2) sized to collect and infiltrate the tributary runoff resulting from the controlling 100-year storm event. The combined capacity of the retention facilities is approximately 27.3 acre-feet. A revised hydrology analysis prepared for the current project estimated that the existing storm drain system has an available retention capacity of approximately 7.5 acre-feet after accounting for the developed uses. TTM No. 38083 involves a net area of 24.93 acres, of which 19.55 acres would consist of single-family residential lots (Lots 1 through 37), approximately 3.15 acres would consist of private streets, and 2.23 acres would consist of open space. The project will follow the approved drainage condition by allowing conveyance into the existing catch basins on Seattle Slew Way. Stormwater from the western part of the project would be conveyed along existing storm drain lines to retention Basin 1. For the east part of the project, runoff would be conveyed along existing storm drain lines to retention Basin 2. It is worth noting that the drainage pattern followed by the proposed project is similar to the existing drainage condition associated with the 20-lot allocation. This is due to the previously established grading, elevations, street design and lot configuration. The available retention capacity at Griffin Ranch is sufficient to address the City’s hydrologic retention requirements and the volumetric-based stormwater quality design quantities for the project area. The runoff volume of 0.25 acre-feet associated with the residential development of 37 lots would be accommodated by the available retention capacity of 7.75 acre-feet. As a result, the project will not generate runoff quantities capable of exceeding the storm drain system. Moreover, the project would not result in stormwater discharge to any publicly operated storm drain system outside of the Griffin Ranch community. Therefore, the revised project would result in similar impacts to stormwater runoff compared to the previous project and impacts for both projects are less than significant. For the period of construction, a stormwater pollution prevention plan and erosion control plan must be prepared, filed, and implemented to comply with the State’s most current Construction General Permit (CGP), Order No. 2009-0009-DWQ, as amended by 2010- 0014-DWQ and 2012-006-DWQ. This regulatory compliance plan will include measures to ensure that the remaining construction activities prevent surface water quality impacts. For post-construction (operational) conditions, additional documentation will be required in the form of a WQMP to comply with the most current standards of the Whitewater River Region Water Quality Management Plan for Urban Runoff and the Whitewater River Watershed MS4 Permit. This WQMP will be subject to review and approval by the City prior to issuance of a grading permit. The existing on-site stormwater infrastructure will continue to provide adequate capacity to prevent uncontrolled runoff discharge. There is no aspect of the remaining residential buildout deviating from the prior analysis, regulatory requirements and the associated stormwater controls. Therefore, by following regulatory program requirements designed to specifically prevent hydrologic, stormwater and surface water impairments, the impacts resulting from the revised project of 37 lots would continue to be less than significant. The 75 City of La Quinta Page 32 Draft Addendum October 2021 revised plans would not result in new or greater significance levels than those disclosed in the previous MND. Overall, the revised project would result in equal impacts to hydrology and water quality compared to the previous project. Onsite drainage is controlled by existing stormwater facilities in the Griffin Ranch property. As concluded in the Griffin Ranch MND and above, both projects would not result in significant impacts to hydrology and water quality. The revised project does not propose substantial changes to the project which will require major revisions of the previous MND or substantial changes with respect to the circumstances under which the project is undertaken that would require major revisions to the previous MND. Additionally, new substantially important information that was not included in the MND is not proposed in the revised project. Therefore, following Section 15162 of the CEQA Guidelines, the revised project is not required to prepare a subsequent MND. XI. Land Use and Planning Griffin Ranch Project MND The MND concluded that the project site would not divide an established community. At the time the MND was written, the area surrounding the Griffin Ranch Specific Plan area consisted of existing low density residential communities. Future low density residential communities were proposed north of the Griffin Ranch SP site. The previous project included a General Plan Amendment (GPA) and a Change of Zone from Very Low Density Residential to Low Density Residential. According to the MND, the previous project proposed 303 residential units, which is less than the amount that could be constructed under the Very Low Density Residential category. Therefore, the MND concluded that the GPA and Change of Zone proposed with the project would not result in impacts. Finally, the MND stated that the Griffin Ranch SP area is located outside the boundary of the mitigation fee for the Coachella Valley Fringe-toed Lizard Habitat Conservation Plan, and the project would result in no impacts to land use and planning. Revised Project As stated throughout this document, the revised project is proposing the subdivision of 20 existing 1-acre residential lots into 37 half-acre lots within the Griffin Ranch SP area. The revised project would not create any new land use barriers, preclude the development of surrounding parcels, or otherwise divide or disrupt the physical arrangement of the surrounding established community, as the areas surrounding the project site are mostly developed and consist of residential buildings and uses. Therefore, the revised project would result in similar impacts compared to the previous project. Both projects would not divide an established community, thus, as determined in the MND and above, no impacts are anticipated. The site is currently designated as Low Density Residential land use and zoning. The land use and zoning designations would not change as a result of implementing the revised project. The revised project proposes to increase the density of the Tract Map 38083 area, however, a Specific Plan Amendment is not required based on substantial conformance through a Director’s Determination. Additionally, the revised project would not consist of 76 City of La Quinta Page 33 Draft Addendum October 2021 components that would conflict with any applicable habitat conservation plans or natural conservation plans, similar to the previous project. The revised project would result in similar impacts to land use plan, policy or regulations, or conservation plans compared to the previous project. Both projects would result in no impacts. No new or more severe impacts associated with land use and planning would occur as a result of implementing the revised project. The revised project does not propose substantial changes to the project which will require major revisions of the previous MND or substantial changes with respect to the circumstances under which the project is undertaken that would require major revisions to the previous MND. Additionally, new substantially important information that was not included in the MND is not proposed in the revised project. Therefore, following Section 15162 of the CEQA Guidelines, the revised project is not required to prepare a subsequent MND. XII. Mineral Resources Griffin Ranch Project MND The MND concluded that the previous project would result in no impacts to mineral resources. The MND determined that the project site is designated as MRZ-1, therefore, the project would not result in the loss of availability of any known mineral resource valuable to the region or to the residents of the state. No impacts were identified in the previous MND. Revised Project Similar to the previous project, under the revised project it would not be feasible to use the project site for mining operation due to the site’s zoning and land use designation. Additionally, the site is located within the Griffin Ranch Specific Plan area and is designated for single family residential homes. Existing residential communities surround the revised project. The City’s General Plan does not identify the project site as an existing or past extraction site. Therefore, implementation of the revised project would result in no impacts related to the loss of local, regional, or state mineral resources, similar to the MND. Overall, the revised project would result in similar impacts to mineral resources compared to the previous project. As concluded in the Griffin Ranch MND and above, both projects would result in no impacts. The revised project does not propose substantial changes to the project which will require major revisions of the previous MND or substantial changes with respect to the circumstances under which the project is undertaken that would require major revisions to the previous MND. Additionally, new substantially important information that was not included in the MND is not proposed in the revised project. Therefore, following Section 15162 of the CEQA Guidelines, the revised project is not required to prepare a subsequent MND. XIII. Noise Griffin Ranch Project MND A project-related noise impact analysis was prepared for the previous project to determine the potential noise impacts associated with the development of the project site. Per the MND, the project would result in short-term (construction), and long-term (operational) impacts 77 City of La Quinta Page 34 Draft Addendum October 2021 related to noise. In particular, the study found that the noise levels associated with vehicular traffic adjacent to the project site would have the potential to exceed the City’s standards for residential land uses without mitigation on both Madison and Avenue 54. The MND stated that on Madison Street, the noise level without mitigation was expected to exceed 75 dBA CNEL, while on Avenue 54 the noise level was expected to exceed 65 dBA CNEL. Additionally, the project was expected to generate noise associated with construction on the project site which would exceed City standards for a short period of time. Therefore, the MND established the following mitigation measures to reduce project-related noise impacts. 1: Construction on the project site shall occur only during the hours prescribed by the La Quinta Municipal Code. 2: All construction equipment shall be properly maintained and mufflered, and the engines shall be equipped with shrouds. 3: Stockpiling and staging areas, as well as servicing and fueling equipment, shall be located as far away from existing residential structures as possible. 4: A six-foot wall on a one foot berm shall be constructed on Madison Street. A six-foot wall shall be constructed on Avenue 54. Both walls shall be of solid construction, without breaks or openings. 5: A final noise analysis shall be completed when final lot layout and pad elevations have been completed to assure that the wall requirements are sufficient to meet the City standards. Therefore, with the implementation of the mitigation measures, impacts associated with noise were expected to be less than significant. Finally, the MND concluded that the Griffin Ranch SP area is not located adjacent to an airport or airstrip, and no impacts would occur. Revised Project The revised project would not require grading or construction beyond what was anticipated in the MND, nor would it change the allowed uses within the project site. No additional grading beyond what was anticipated in the MND would occur. As such, no new or more impacts related to noise would occur. Impacts would be less than significant, similar to the MND. Construction activities associated with the revised project are only permitted within the construction hours established by the City. During construction, the revised project will be subject to mitigation measures 1, 2, 3 and 5 (listed above). Mitigation measure 4 is not applicable to the revised project because the frontages along Madison Street and Avenue 54 have been developed. The revised project is expected to follow common industry standards that will help limit noise level increases. For example, all construction equipment, fixed or mobile, should be equipped with properly operating and maintained mufflers and the engines should be equipped with shrouds. Approved haul routes shall be used to minimize exposure of sensitive receptors to potential adverse levels from hauling operations. All construction equipment shall be in proper working order and maintained to reduce backfires. Similar to the MND, construction and operational noise generated by the revised project is expected to be less than significant with the implementation of 1, 2, 3 and 5, as established in the MND. 78 City of La Quinta Page 35 Draft Addendum October 2021 The operation of the revised project is the same as the operations analyzed in the MND. While the revised project would result in an increase in noise levels compared to the existing partially undeveloped condition, the nature of the residential uses is not expected to result in the generation of noise levels that would surpass the community noise and land use compatibility standards. In regard to noise generated by project traffic, the revised project would not introduce a substantial amount of additional vehicle travel to the site. The revised project would not significantly alter on- or off-site noise generation, as the proposed uses would be similar to the existing uses in the surrounding area and the increase in lot count (additional 17 lots) would still result in less dwelling units per acre than allowed in the existing Low Density Residential land use and zoning designation, which allows 2 dwelling units per acre (du/ac). Similar to the MND, noise levels associated with the revised project would not conflict with the City’s Noise Ordinance or the General Plan noise standards, resulting in less than significant impacts. Additionally, the revised project is not located within two miles of a public airport or public use airport, or within the vicinity of a private airstrip. Therefore, there would be no impacts. With the implementation of mitigation measures 1, 2, 3 and 5, the revised project would result in less than significant impacts. Overall, the revised project would result in slightly increased impacts to noise compared to the previous project due to the addition of 17 residential lots. However, impacts from the revised project would be less than significant with the implementation of the mitigation measures of the Griffin Ranch MND, as with the previous project.. The revised project does not propose substantial changes to the project which will require major revisions of the previous MND or substantial changes with respect to the circumstances under which the project is undertaken that would require major revisions to the previous MND. Additionally, new substantially important information that was not included in the MND is not proposed in the revised project. Therefore, following Section 15162 of the CEQA Guidelines, the revised project is not required to prepare a subsequent MND. XIV. Population and Housing Griffin Ranch Project MND According to the MND, the previous project would result in less than significant and no impacts to population and housing. At the time the MND was written, the Griffin Ranch SP area was designated Very Low and Low Density Residential. Per the MND, the General Plan land use designations for the Griffin Ranch SP area had the potential to allow up to 478 single family homes on the project site, resulting in 1,200 persons on the 199-acre property. The development of the Griffin Ranch project proposed a General Plan Amendment and Zone Change to allow Low Density Residential land uses and zoning, which would generate 303 residential lots, with a maximum population of about 758 persons. The proposed 303 was 62 percent fewer than permitted under the previous Very Low and Low Density Residential land use designations on the Griffin Ranch property. The MND stated that even with the entire site at Very Low Density Residential, the project itself would remain 237 persons and 95 units less than the maximum population potential under that land use designation. While the specific plan provides development standards to 79 City of La Quinta Page 36 Draft Addendum October 2021 govern the project as designed, they are based on a combination of Low Density and Very Low Density standards. Allowing the Low Density Residential zoning would not affect the project, and would allow greater flexibility in housing and lot design. It would also encourage a greater amount of open space in a subsequent development in the event this project does not build out and the specific plan is revised. Due to the vacant character of the site, the MND determined that the site would not displace any existing housing or require replacement housing. Therefore, the MND concluded that there would be no impact to replacement housing as a result of the project and impacts associated with the proposed project are expected to be less than significant. Revised Project The revised project would not displace any existing housing units or people, as the site is vacant and located in La Quinta’s Low Density Residential land use and zoning designation. The revised project proposes to subdivide 20, 1-acre lots to 37 half-acre lots, adding 17 additional lots to an approximately 25-acre property (TTM No. 38083). The addition of the 17 residential lots would increase the population of the 25-acre site by approximately 44 persons, based on the City’s current 2.60 persons per household, as established by the Department of Finance (DOF). The 20 lots would generate approximately 52 residents, while the revised project could generate 96 residents on the 25-acre area. However, Low Density Residential zones in La Quinta allows two to four dwelling units per acre. Therefore, the 25- acre site could accommodate up to 100 dwelling units, generating 260 residents on the site. The potential population increase of 44 persons is not substantial since the number of units proposed for the revised project is consistent with the existing Low Density Residential designation. Thus, the revised project would not result in any substantial increase or decrease of population. Similar to the MND, impacts to population growth would be less than significant. The additional 17 lots onsite would also not result in indirect impacts such as the need for additional infrastructure development. The project site, which is a part of the Griffin Ranch Specific Plan area, is currently provided with existing infrastructure, such as water, sewer, and cable since the surrounding area is developed as a part of the Griffin Ranch Specific Plan. Therefore, the revised project would not result in significant indirect growth impacts. Similar to the MND, the revised project would also not displace any existing housing or require replacement housing, due to the vacant character of the site. No impacts are anticipated. Overall, the revised project would result in slightly increased population on the project site compared to the previous project due to the proposed addition of 17 residential lots. However, as stated above, impacts would not be significant. As concluded in the Griffin Ranch MND and above, both projects would result in less than significant impacts. The revised project does not propose substantial changes to the project which will require major revisions of the previous MND or substantial changes with respect to the circumstances under which the project is undertaken that would require major revisions to the previous MND. Additionally, new substantially important information that was not included in the MND is not proposed in the revised project. Therefore, following Section 15162 of the CEQA Guidelines, the revised project is not required to prepare a subsequent MND. XV. Public Services 80 City of La Quinta Page 37 Draft Addendum October 2021 Griffin Ranch Project MND The MND found that impacts to public services would be less than significant. Buildout of the proposed project will generate property tax and sales tax which would offset the costs of added police and fire services, as well as the costs of general government. The project will be required to pay the mandated school fees in place at the time of issuance of building permits. Coachella Valley Unified School District (CVUSD) requested a bus turnout on Avenue 54, but no such turnout has been requested by Sunline Transit. The MND states that the City would require the applicant to work with Sunline and CVUSD in finding an appropriate turnout and incorporating it into improvement plans for Avenue 54. The project was also expected to provide on-site recreational facilities, and also pay the City’s park fees for development of off-site park facilities. The MND determined that the project would result in less than significant impacts to public services. Revised Project Similar to the MND, the revised project would result in less than significant impacts to public facilities. The revised project would result in less than significant impacts to fire protection, police services, and school facilities, similar to the proposed project. Therefore, the revised project will be required to comply with the City’s Development Impact Fees (DIF) to assist with the funding of public facilities and services, including fire and police services. The revised project would also be required to pay developer impact fees to the CVUSD to assist in offsetting impacts to school facilities. The developer impact fees for the District have increased since the time the MND was written. Currently, fees are $4.08 per square foot for residential, and $0.66 per square foot for commercial. The revised project would be required to pay the most current fees. However, with the payment of the DIFs for public facilities and services, and developer impact fees for the school facilities and parks, the revised project would result in less than significant impacts to public services, similar to the previous project. Overall, the revised project would result in slightly increased needs for public services compared to the previous project due to the proposed addition of 17 residential lots. However, as stated above, the revised project is required to pay DIF fees to accommodate the increased needs and impacts would be less than significant. As concluded in the Griffin Ranch MND and above, both projects would result in less than significant impacts. The revised project does not propose substantial changes to the project which will require major revisions of the previous MND or substantial changes with respect to the circumstances under which the project is undertaken that would require major revisions to the previous MND. Additionally, new substantially important information that was not included in the MND is not proposed in the revised project. Therefore, following Section 15162 of the CEQA Guidelines, the revised project is not required to prepare a subsequent MND. XVI. Recreation Griffin Ranch Project MND 81 City of La Quinta Page 38 Draft Addendum October 2021 According to the MND, the previous project proposed the development of on-site recreational spaces/retention areas. The previous project also proposed the removal of a pedestrian/hiking trail on the Avenue 55 alignment. This trail was identified in the City’s General Plan and ran east from Madison Street, one-half mile along the Griffin Ranch property’s southern boundary. At the time the MND was written, the trail did not lead to any planned or existing park or other public facility, nor was it usable within the existing improvements for the area. Additionally, Avenue 55 was not planned, either on the Circulation Element or as a local street. Therefore, it was recommended that the segment be removed from the General Plan as part of the General Plan Amendment proposed for the previous project. The MND also stated that the previous project would contribute park fees for off-site park development. Therefore, the MND stated that no impacts to City recreational facilities are expected. Revised Project The revised project proposes to subdivide 20, 1-acre lots, to 37 half-acre lots for residential dwelling units. The addition of 17 proposed residential lots is not proposed to substantially increase the use of existing neighborhood and regional parks or other recreational facilities such that substantial physical deterioration of the facilities would occur or be accelerated. The Griffin Ranch SP area recreation facilities includes open space, a community center with swimming pool, tennis and pickleball courts. The residents of the revised project will utilize these existing facilities. Similar to the MND, the revised project would not result in impacts to public recreation facilities in the City of La Quinta. Overall, the revised project would result in equal impacts to recreational facilities compared to the previous project, although the revised project proposes 17 additional residential lots. However, as stated above, impacts would be less than significant since the Griffin Ranch neighborhood provides recreational facilities in the community. It is likely that the residents of the revised project will utilize the Griffin Ranch recreational facilities. As concluded in the Griffin Ranch MND and above, both projects would result in less than significant impacts. The revised project does not propose substantial changes to the project which will require major revisions of the previous MND or substantial changes with respect to the circumstances under which the project is undertaken that would require major revisions to the previous MND. Additionally, new substantially important information that was not included in the MND is not proposed in the revised project. Therefore, following Section 15162 of the CEQA Guidelines, the revised project is not required to prepare a subsequent MND. XVII. Transportation Griffin Ranch Project MND The 199-acre project setting evaluated by the prior MND was characterized as partially developed with agricultural and equestrian land uses. The surrounding context included a combination of undeveloped, residential and golf course uses. The 2005 Griffin Ranch Specific Plan included a Tentative Tract Map to subdivide the property into 303 single family residential lots, as well as lettered lots for a community clubhouse, streets, retention basins, three well sites and an internal equestrian/pedestrian trail system. The project also included a General Plan Amendment and Zone Change to 82 City of La Quinta Page 39 Draft Addendum October 2021 modify the land use designation from Very Low Density Residential and Very Low Density/Equestrian Overlay to Low Density Residential. Additionally, the project also proposed to process a General Plan Amendment to modify the roadway classification of Madison Street from a Major Arterial to a Primary Arterial. A project specific Traffic Impact Analysis was prepared by Endo Engineering. The proposed 199-acre Project site consisted of 303 single-family dwelling units in the City of La Quinta. As part of the proposed Project, the following improvements were included as Mitigation Measures: 1 Madison Street and Avenue 54 shall be improved to their buildout half width with development of the proposed project. 2 A Class II bikeway and golf cart path shall be located on Madison and Avenue 54. 3 A left turn pocket shall be constructed in the median on Madison Street at the project entry to allow for deceleration. 4 Lane geometrics shall be as shown on Exhibit 5.1 of the traffic study. 5 The project proponent shall contribute their fair share to signalization of Jefferson Street and Avenue 54, Madison Street and Avenue 54 and Monroe Street and Avenue 54. The Institute of Transportation Engineers (ITE) trip generation rates were used to calculate the number of trips forecast to be generated by the proposed Project. The proposed Project was forecast to generate approximately 2,900 average daily trips (ADT), which included approximately 223 a.m. peak hour trips and approximately 292 p.m. peak hour trips. The focused analysis also found, based on approved projects in the area, that potential trips on Madison Street would be reduced from the General Plan assumption of 41,300 – 43,700 daily trips (based on location) to 30,020 – 32,420 daily trips. The capacity of a 6-lane divided Major Arterial roadway is 57,000 daily trips, while the capacity of a 4-lane divided Primary Arterial roadway is 38,000 daily trips. The determination was made that the reduction in daily trips would lead to a reduction in the appropriate width of Madison Street. The Primary Arterial (4-lane) classification and cross section were determined to be acceptable to carry the buildout traffic. The project applicant’s payment to the Coachella Valley Association of Governments (CVAG) Transportation Uniform Mitigation Fund (TUMF) Fee Program would have been required as a condition of the approval process. The fair share contribution of the project to the City of La Quinta Fee Program for signalization was required as a mitigation measure. Following compliance with Mitigation Measures and Standard Conditions including adjacent roadway improvements and payment of TUMF and Development Impact Fees, the project was expected to result in an acceptable increase in traffic levels on the local roadways and less than significant impacts were expected. Revised Project 83 City of La Quinta Page 40 Draft Addendum October 2021 The majority of the 2005 Griffin Ranch Specific Plan project has been developed including all roadway improvements aside from the two roadways that would abut and serve the proposed project. These roadways include Seattle Slew Way and Afleet Alex Way. Currently 20 lots remain vacant. The area that contains these 20 lots is the property included in the proposed Tract Map 38083. The revised project proposes the subdivision of the 20 existing 1-acre residential lots into 37 half-acre lots. The 20 lots are currently graded and stabilized with previously installed utility infrastructure and are centrally located within the Griffin Ranch community, directly adjacent to the Merv Griffin Estate (not a part of the project). The revised project proposes to increase the density of the Tract Map 38083 area. There will be no revisions to the street layout. Buildout of Tract Map 38083 would require the same categories of compliance plans and final engineering design approvals required of the 2005 Plan to comply with City-specific engineering standards. The following existing roadways provide access to the project: Madison Street – Madison Street is a north-south oriented roadway located west of the project and classified as a 4-lane divided Primary Arterial in the City of La Quinta Circulation Plan. Avenue 54 – Avenue 54 is an east-west oriented roadway located north of the project and classified as a 4-lane divided primary arterial in the City of La Quinta Circulation Plan. Vehicle Miles Traveled Changes to the CEQA Guidelines, associated with SB 743, were adopted in December 2018 which require all lead agencies to implement Vehicle Miles Traveled (VMT) as a replacement for automobile delay-based level of service (LOS) as the new measure for identifying transportation impacts for land use projects. This statewide mandate went into effect July 1, 2020. To aid in this transition, the Governor’s Office of Planning and Research (OPR) released a Technical Advisory on Evaluating Transportation Impacts to CEQA (December of 2018) (Technical Advisory). LOS analysis is currently utilized to determine General Plan Consistency. Per the request of the City of La Quinta TTM 38083 VMT Screening and Trip Generation/Access Assessment was prepared by Urban Crossroads, Inc. A CEQA MND Addendum does not require analysis of topics that were not included in the CEQA Guidelines at the time of adoption of the original MND. However, as requested by the City of La Quinta, and for informational purposes, a VMT screening is included in this MND Addendum. The City of La Quinta utilizes the City of La Quinta Vehicle Miles Traveled Analysis Policy for VMT assessments and sets forth screening criteria under which projects are not required to submit detailed VMT analysis. This guidance for determination of non-significant VMT impact is primarily intended to avoid unnecessary analysis and findings that would be inconsistent with the intent of SB 743. The City of La Quinta’s VMT Analysis Policy outlines three types of screening criteria for development projects. The three include:  Project Type Screening: Small projects and Local serving projects may be presumed to have a less than significant impact. Small projects are those with low trip generation per existing CEQA exemptions or result in 3,000 Metric Tons of 84 City of La Quinta Page 41 Draft Addendum October 2021 Carbon Equivalent (MTCO2e) or less. Local serving projects are determined to shorten non-discretionary trips by putting goods and services closer to residents, resulting in an overall reduction in VMT.  Transit Priority Area (TPA) Screening: Projects located within a half-mile area around an existing major transit stop or an existing stop along a high-quality transit corridor (TPA) may be presumed to have a less than significant impact absent substantial evidence to the contrary.  Low VMT Area Screening: Residential and office projects located within a low VMT- generating area may be presumed to have a less than significant impact absent substantial evidence to the contrary. In addition, other employment-related and mixed-use land use projects may qualify for the use of screening if the project can reasonably be expected to generate VMT per resident, per worker, or per service population that is similar to the existing land uses in the low VMT area. The project has been reviewed against the City’s VMT Analysis Policy for VMT screening and based on its size as a small single-family housing project less than or equal to 140 dwelling units, no further VMT analysis is needed. Project Trip Generation For this assessment trip generation rates are based on data collected by the Institute of Transportation Engineers (ITE) in the Trip Generation Manual, 10th Edition, 2017, and the Trip Generation Manual, 10th Edition Supplement, February 2020. The ITE Land Use (LU) Code 210 – Single Family Detached has been identified as the appropriate ITE description of the proposed project. Trip generation rates used to compare approve and proposed traffic for the site are shown in Table XVII-1 and trip generation estimates for the currently approved 20 residences are shown in Table XVII-2. Table XVII-1 ITE Trip Generation Rates (Note 1) Land Use ITE LU Code Quantity (Note 2) AM Peak Hour PM Peak Hour Daily In:Out Split Total In:Out Split Total Single Family Detached 210 DU 19:55 0.74 62:37 0.99 9.44 1.

DU = Dwelling Units ITE trip rates were applied to the existing project as illustrated in Table XVII-2. The currently approved 20 Dwelling Units are anticipated to generate a total of approximately 189 trip-ends per day with 15 vehicles per hour during the AM peak hour and 19 vehicles per hour during the PM peak hour.

The proposed 37 Dwelling Units are anticipated to generate a total of approximately 349 trip-ends per day with 27 vehicles per hour during the AM peak hour and 37 vehicles per hour during the PM peak hour. The net difference between the approved and proposed project are also illustrated in Table XVII-3. The proposed project is anticipated to generate approximately 160 additional trip- ends per day when compared to the approved residential site, with 12 more vehicles per hour during the AM peak hour and 18 more vehicles per hour during the PM peak hour.

DU = Dwelling Units 2. Difference between approved residential for the site and the proposed project. Site Access and Circulation Context The proposed project will have three points of access. Merv Griffin Way provides a primary gated access point for residents and guests. The intersection of Madison Street/Merv Griffin Way (#3) includes a northbound right turn lane and southbound left turn lane to accommodate inbound turning movements. Seattle Slew Way connects the project to Merv Griffin Way and outward to Madison Street at the southwest corner of the site. An additional gated access point for residents only is located at the Alysheba Drive/Avenue 54 intersection (#1). Donali Street connects the project to Alysheba Drive and outward to avenue 54 at the northwest corner of the site. A third gated access point is located at the intersection of Merv Griffin Way/Avenue 54 (#2) for residents only. Bold Ruler Way connects the project to Merv Griffin Way and outward to Avenue 54. This access point has a westbound left turn lane for inbound traffic. Trip Distribution and Assignment The patten of trip distribution is influenced by the location of the site, the location of surrounding uses, and the proximity to the regional freeway system. Exhibit 7, Project Trip Distribution, illustrates the estimated project traffic distribution pattern. Intersection turning movements are described subsequently for the existing and proposed project. Madison Street/Merv Griffin Way (#3) Northbound Right Turn Lane: The approved site residential (20 DU) adds 1 vehicle during the AM peak hour and 3 vehicles during the PM peak hour to the northbound right turn lane. The proposed project (37 DU) contributes 1 additional vehicle during the AM peak hour and 3 vehicles during the PM peak hour to the northbound right turn lane. Madison Street/Merv Griffin Way (#3) Southbound Left Turn Lane: The approved site residential (20 DU) adds 1 vehicle during the AM peak hour and 2 vehicles during the PM peak hour to the southbound left turn lane. The proposed project (37 DU) contributes an additional 2 vehicles during the PM peak hour to the southbound left turn lane. 86 City of La Quinta Page 43 Draft Addendum October 2021 Alysheba Drive/Avenue 54 (#1) and Merv Griffin Way/Avenue 54 (#2) all Turn Lanes: The volumes added by the proposed project (in addition to the approved site residential) at individual turning movements are 2 vehicles or less on all inbound and outbound turns. Conclusions The revised project would not introduce a substantial amount of additional vehicle trips to the area. The project has been reviewed for VMT screening based on its size as a small project, additional VMT analysis is not necessary and there would be no impact regarding VMT. And finally, the proposed project will have three access points. Each access point has existing lane geometrics which have been planned to serve buildout of the Griffin Ranch Specific Plan area. Volumes added by the proposed project (in addition to the approved site residential) at both the AM and PM peak hours are considered nominal. The revised project would not result in increased vehicular conflicts, as the proposed uses would be similar to the prior proposed uses and existing uses in the surrounding area. The project is expected to result in less than significant impacts similar to the previous project. Overall, the revised project would result in slightly increased vehicle volume compared to the previous project due to the proposed addition of 17 residential lots. However, as stated above, impacts would be less than significant. As concluded in the Griffin Ranch MND and above, both projects would not result in significant impacts. The revised project does not propose substantial changes to the project which will require major revisions of the previous MND or substantial changes with respect to the circumstances under which the project is undertaken that would require major revisions to the previous MND. Additionally, new substantially important information that was not included in the MND is not proposed in the revised project. Therefore, following Section 15162 of the CEQA Guidelines, the revised project is not required to prepare a subsequent MND. 87 N.T.S.

Utilities and Service Systems Griffin Ranch Project MND The MND determined that the project would result in less than significant impacts to utilities and service systems including water infrastructure and supply, wastewater infrastructure, stormwater infrastructure, or solid waste facilities. According to the MND, utilities are available to the site or in the immediate facility. Service providers will collect connection and usage fees to balance the cost of providing services. Therefore, the MND concluded that the project would result in less than significant impacts on utility services. Revised Project Similar to the MND, the revised project would not result in significant impacts to utilities and service systems. The revised project would not require grading or construction beyond what was anticipated in the MND and would not change the allowable uses. As such, no new or more severe impacts related to utilities and service systems would occur. Similar to the MND, wastewater generated by the revised project is expected to be minimal. The revised project is not expected to exceed wastewater treatment requirements of the State Regional Water Quality Control Board (SRWQCB) (Colorado River Basin). In addition, City and other local and governmental agency review will ensure compliance with all current and applicable wastewater treatment requirements. Similar to the MND, the revised project proposes to connect to existing waste and sewer infrastructure. The revised project would undergo review by the Coachella Valley Water District (CVWD) and City staff to ensure wastewater capacity and compliance with the current wastewater treatment requirements. Additionally, sewer installation and connection fees in place at the time of development will be collected by CVWD. No new or expanded treatment facilities are anticipated from project implementation. The revised project would result in similar impacts to wastewater compared to the previous project. Neither project would result in significant impacts to wastewater infrastructure. The revised project would be expected to incorporate storm drain and flood control facilities to prevent changes to local drainage conditions (patterns, quantities, or velocities) and adverse erosion and sedimentation impacts. This entitlement would not change the land use type or increase the tributary area to the existing storm drain system, which is privately maintained to serve the entire Griffin Ranch community. TTM No. 38083 would follow the approved drainage condition by allowing conveyance into the existing catch basins on Seattle Slew Way. For the west part of the project, stormwater would be conveyed to existing retention Basin 1. For the east part of the project, runoff would be conveyed to Basin 2. Less than significant impacts to stormwater drainage are expected. The revised project would result in equal impacts to stormwater drainage compared to the previous project. Neither project would result in significant impacts. Like the previous project, the revised project will be required to comply with all construction requirements and best management practices through the life of the project. Regarding water supply, the revised project would be expected to follow water conservation guidelines to mitigate impacts to public water supplies. Examples of these water conservation methods 89 City of La Quinta Page 46 Draft Addendum October 2021 include water conserving plumbing fixtures, drought tolerant landscaping, and drip irrigation systems. The revised project proposes to connect to the existing water lines. Additional domestic water improvements necessary to serve this development will be identified by CVWD and included as conditions of approval by the City of La Quinta during the City’s standard review process. Less than significant impacts to water supply are expected. The revised project would result in similar impacts to water consumption and supply compared to the previous project. As determined in the Griffin Ranch MND and above, both projects would not result in significant impacts related to water supply. In regard to landfill capacity, solid waste generated by the revised project would consist of standard household/office waste. Residential waste and recycling collected from the revised project will be hauled to the Edom Hill Transfer Station. Waste from this transfer station is then sent to a permitted landfill or recycling facility outside of the Coachella Valley. These include Badlands Disposal Site, El Sobrante Sanitary Landfill and Lamb Canyon Disposal Site. CalRecycle data indicates that these landfills have 40-50% of their remaining estimated capacity. Less than significant impacts to solid waste are expected. Additionally, the revised project would comply with all applicable solid waste statutes and guidelines. No impacts are expected relative to solid waste statues and regulations. The revised project would result in similar impacts to solid waste generation compared to the previous project. Neither project would result in significant impacts to landfills or statues and regulations related to solid waste. Overall, the revised project would result in similar impacts to utilities and service systems compared to the previous project. However, as concluded in the Griffin Ranch MND and above, both projects would not result in significant impacts. The revised project does not propose substantial changes to the project which will require major revisions of the previous MND or substantial changes with respect to the circumstances under which the project is undertaken that would require major revisions to the previous MND. Additionally, new substantially important information that was not included in the MND is not proposed in the revised project. Therefore, following Section 15162 of the CEQA Guidelines, the revised project is not required to prepare a subsequent MND. XIX. Wildfire Griffin Ranch Project MND The Griffin Ranch Project MND did not discuss project-related wildfire impacts since it was not a required topic by CEQA at the time the MND was written and adopted. Revised Project A CEQA MND Addendum does not require analysis of topics that were not required during the time that the original CEQA document was adopted, however for informational purposes, new environmental topics required by the most current CEQA Guidelines have been included, such as this discussion of wildfires. The revised project is located in an urban context of the City of La Quinta, surrounded by residential developments to the north, west, south, and east. Human activities on the project property, such as clearing of native vegetation and grading, is evident onsite. The revised project is located within the Griffin Ranch Specific Plan area, which proposes a master- planned community consisting of residential lots, open space recreational areas, and a community clubhouse area. A majority of the Griffin Ranch Specific Plan area has been 90 City of La Quinta Page 47 Draft Addendum October 2021 developed, apart from the area east of the revised project and scattered lots south and southeast of the revised project. According to CAL Fire’s Fire Hazard Severity Zones (FHSZ) in State Responsibility Areas (SRA) Map, the project is not located in an SRA or located in an area classified as very high fire hazard severity zone (VHFHSZ). Additionally, the project property is not located in or near lands classified as high or moderate fire hazard severity zones. Areas classified as SRA or VHFHSZs in the City are located in the southern portion of La Quinta, in the Santa Rosa Mountains. However, wildfires in the undeveloped local mountains adjacent to the Coachella Valley cities (i.e., Santa Rosa Mountains) are not common due to the mountain’s natural terrain, which is steep, rocky, and dry. Furthermore, the Santa Rosa Mountains are made up primarily of Granitic rock and sparse desert vegetation. The topographic character of the Santa Rosa Mountains is not conducive for the growth of dense vegetation; and as a result, the amount of fuel available for wildland fires is limited. Additionally, the distance between the existing vegetation does not allow wildfires to spread easily. Due to the project’s location in an urban context of the City, and the revised project’s distance from SRAs and areas designated as VHFHSZs, impacts of wildfires are not anticipated. XX. Mandatory Findings of Significance Griffin Ranch Project MND The MND found that the 199-acre Griffin Ranch Project would result in potentially significant impacts related to air quality, cultural resources, noise, transportation and traffic. As previously described, all of these impacts were reduced to below a significant level with the implementation of mitigation measures. All other project impacts were found to be less than significant without mitigation, and no deficiencies related to the City’s General Plan were found to occur. The project would not result in environmental effects that would cause a substantial adverse effect on human beings either directly or indirectly. Revised Project Similar to the previous project analyzed in the MND, the revised project would result in potentially significant impacts, however, these impacts would be reduced to less than significant through implementation of the mitigation measures outlined in the MND. No additional impacts were identified as a result of the revised project, and no deficiencies were identified related to the City’s General Plan as a result of the residential project revisions. The revised project does not propose substantial changes to the project which will require major revisions of the previous MND or substantial changes with respect to the circumstances under which the project is undertaken that would require major revisions to the previous MND. Additionally, new substantially important information that was not included in the MND is not proposed in the revised project. Therefore, following Section 15162 of the CEQA Guidelines, the revised project is not required to prepare a subsequent MND. 91 City of La Quinta Page 48 Draft Addendum October 2021 Sources California Emission Estimator Model (CalEEMod) Version 2020.4.0, California Air Pollution Control Officers Association (CAPCOA), May 2021.

(Exhibit 1-Vicinity) The proposed project is single family subdivision. This Specific Plan is intended to meet the requirements for a Specific Plan as set forth in State law. The State authorizes cities and counties to adopt Specific Plans as an appropriate tool in implementing their General Plans. Such a plan is to include the detailed regulations, conditions, programs, and any proposed legislation that is necessary for the systematic implementation of the General Plan. The Specific Plan provides the linkage between the General Plan, the general goals and policies of the City, and the detailed implementation of that plan with tools such as zoning ordinances, subdivision ordinances, and the like. The Government Code (Section 65451) sets forth the minimum requirements of a Specific Plan and states: "A Specific Plan shall include a text and diagram or diagrams which specify all of the following in detail: 1). The distribution, location, and extent of the uses of land, including open space, within the area covered by the plan. 2). The proposed distribution, location and extent and intensity of major components of public and private transportation, sewage, water, drainage, solid waste disposal, energy, and other essential facilities proposed to be located within the area covered by the plan and needed to support the land uses described by the plan. 3). Standards and criteria by which development will proceed, and standards for the conservation, development, and utilization of natural resources, where applicable. As Adopted January 4, 2005 Page 1 of 62 98 Griffin Ranch Specific Plan City of La Quinta 4). A program of implementation measures including regulations, programs, public works projects, and financing measures necessary to carry out paragraphs (1), (2), and (3)." The Specific Plan shall include a statement of the relationship of the specific plan to the General Plan. The establishment of specific performance, design, and development standards is set forth to guide the development of the subject property in such a way as to implement the General Plan while maintaining some flexibility to respond to changing conditions which may be a factor in any long term development program. This document acts to augment the City's Zoning Ordinance by providing particular design guidelines, a tailored list of allowable, conditionally allowable, and prohibited uses for the site, and unique development standards. The site plan, architectural and landscape illustrations in the Specific Plan establish a design theme with detailed perspectives. These illustrations are conceptual and do not constitute precise pre- construction drawings. As Adopted January 4, 2005 Page 2 of 62 99 Griffin Ranch Specific Plan City of La Quinta EXECUTIVE SUMMARY Griffin Ranch is a proposed single family subdivision located on approximately 199 +/- acres of property located on the south side of Avenue 54 and east of Madison Street within the City of La Quinta (Exhibit 2). The land use designation on the City's General Plan is LDR-Low Density Residential with up to 4 du/acre on the southwest corner of the site, and VLDR–Very Low Density Residential with up to 2 du/acre on the remainder of the site (Exhibit 6). The zoning is RL, Low Density Residential (2- 4du/ac) and RVL, Very Low Density (0-2du/ac) both designations have an Equestrian Overlay (Exhibit 5). This designation permits the development of single family homes on large lots. The site has approximately 2,600 feet of frontage on the east side Madison Street and 2,300 feet of frontage along the south side of 54th Avenue. Madison Street is designated as a Major Arterial (6D) and 54th Avenue as a Secondary Arterial (4U) according to the City’s General Plan. Both 54th Avenue and Madison Street are designated as an Agrarian Image Corridors and require Class II Bike Trails (On Road Bicycle Lane) along Madison Street and Pedestrian/ Hiking Trails along 54th Avenue and Madison Street. The surrounding properties are vacant with scattered residences to the north, single family residences and vacant land to the east, and PGA West to the west and to the south. Site photos are illustrated on Exhibits 7 and 7a. The project is a single family subdivision with common recreational facilities (Exhibit 4). The homes will be a mixture of one and two story structures on lots ranging in size from a minimum of 11,000 to over 40,000 square feet in size. In the southwest corner of the site will be an 11 +/- acre Community Recreation and Open Space Area available for equestrian uses with access to a central riding/arena area and on site trails. This area will also include a clubhouse facility for residents and members with such amenities as pool, spa and tennis courts (See Exhibits 20 and 30). As Adopted January 4, 2005 Page 3 of 62 100 Griffin Ranch Specific Plan City of La Quinta Landscaping and a meandering multi use trail will surround the project along its entire public street frontage. Exhibit 8 illustrates the Tentative Tract Map/Site Plan for the project. Three entrances to the site are proposed. The primary entrance on Madison Street shall be for resident and guest entry. This entry shall be staffed with security personnel. The two secondary entrances located on 54th Avenue will be for residents utilizing card transponders. The project will contain private streets and an equestrian multi- purpose trail. As Adopted January 4, 2005 Page 4 of 62 101 Griffin Ranch Specific Plan City of La Quinta THE PROCESS The purpose of a Specific Plan is to provide a detailed plan for a selected area within the City for the purpose of implementing the General Plan. This Specific Plan outlines and directs all facets of development for this site. The standards of development delineated in this Specific Plan create a link between the General Plan and the Zoning Ordinance. Development of the project is allowed through adoption of a Mitigated Negative Declaration of Environmental Impact, amendment to the General Plan Circulation, Change of Zone from RVL to RL (Residential Low), approval of the Griffin Ranch Specific Plan and approval of Tentative Tract Map No. 32879 (Exhibit 8) to subdivide 199 +/- acres into 303 lots. Implementation of this Specific Plan is intended to carry out the goals and policies contained in the General Plan of the City of La Quinta in a planned and orderly fashion. The land use designation on the City's General Plan is LDR - Low Density Residential up to 4 du/acres, and VLDR – Very Low Density Residential up to 2 du/acre. The zoning is RL - Low Density Residential (2-4 du/acre) and RVL - Very Low Density Residential (0-2 du/acre) both designations have an Equestrian Overlay. The proposed project density of 1.52 dwelling units/acre is below the maximum permitted of 2 dwelling units per acre (20% of the site is zoned for 4 dwelling units per acre). The 303 units proposed are below the combined overall allowable number of 468 units. A comparison of the project’s development plan to the City’s General Plan Goals and Policies are contained in Appendix One. The City of La Quinta, as Lead Agency for the project, required an Environmental Assessment to include an Archaeological Report, Traffic Study, Geotechnical Investigation, Biological Assessment and Noise and Air Quality analysis of the site. A summary of each study’s findings follows. As Adopted January 4, 2005 Page 5 of 62 102 Griffin Ranch Specific Plan City of La Quinta CRM Tech completed the Archaeological Report. This study determined in its findings that the site does not constitute as a potential historic resource. The study also determined that the site’s historical significance cannot be ascertained without further archaeological excavations. An Archaeological testing and evaluation program is recommended as mitigation. Endo Engineering prepared the Traffic Impact Study as well as the noise and air Quality Analysis and identified mitigation measures to be incorporated into the project’s condition of approval to minimize the potential for any adverse impacts associated with the development. Sladden Engineering prepared the Geotechnical Investigation and determined that the proposed site is feasible for residential development. JWC Ecological Consultants prepared the Biological Assessment and determined that the project will have no significant adverse impacts to the biological resources of the region. The project site contains the proper land use designation for the uses proposed. Exhibit 5 depicts the zoning on the site and the surrounding parcels. The City of La Quinta requires a Specific Plan to provide a detailed plan for modifications to the development standards. RELATIONSHIP TO OTHER AGENCIES In addition to City approvals, permits will be required by the Coachella Valley Water District (CVWD) for improvements to the water and sewer lines. Other infrastructure improvements will be required by Imperial Irrigation District (electrical power), Verizon for telephone service and Time Warner for cable TV service.

The site is vacant and there are no significant landforms or scenic features on the site except for a private ranch home in the out parcel of the site. The project will provide a grouping of lots into custom homes and semi-custom home sites. Custom homes will be built on 1-acre lots with semi-custom homes built on lots ranging in size from 11,000 to 40,000 square feet (Exhibit 4). The Plan will integrate architecture and landscape architecture into a pleasant residential setting with equestrian amenities. The Griffin Ranch will be a gated community consisting of up to 303 single-family homes ranging in size from 2,800 to approximately 5,500 square feet, incorporating equestrian amenities accessing a common riding area and trails. The custom lots will be built around the out parcel of the site having south or west views of the area. Most homes will enjoy a view of the Santa Rosa Mountains and will accommodate the construction of a pool and spa in the rear yard. Each floor plan will have three to four front elevations illustrating one of the following styles: Andalusian, Monterey, Spanish Colonial, Contemporary Mexican, and Italian Farmhouse. The overall theme envisions earth-tone stucco colors accented by the use of arches, courtyards, smooth style stucco and clay roof tiles. Other exterior standard features include detached casitas, covered rear yard porches and patios, three car garages, masonry walls, and front yard landscaping. Griffin Ranch will be surrounded by a masonry wall up to 8.5’ in height with smooth stucco and metal ornamental iron, pilasters and desert friendly landscaping on the perimeter, including the multi-purpose trail along Madison Street and 54th Avenue. As Adopted January 4, 2005 Page 16 of 62 113 Griffin Ranch Specific Plan City of La Quinta There will be three gated entries into the project. The main entry on Madison Street will be staffed by security personnel and utilized for resident and guest entry. The two entries on 54th Avenue will be for resident access only. Each gated entry will include monument signage. The main gated entry on Madison Street will include extensive entry features and landscaping. A meandering multi purpose trail will be provided along the perimeter of the site with exception of along the perimeter at the southern boundary. The two secondary entries on 54th Avenue will also have a meandering multi purpose trail. The project will include privately maintained streets and open space with low profile lighting to preserve the visibility of the naturally clear skies of the desert. Art in Public Places and Recreation The requirement for Art in Public Places will be satisfied in accordance with Chapter 2.65 of the La Quinta Municipal Code. Recreational requirements will be satisfied in accordance with Section 13.65 of the La Quinta Municipal Code. Phasing Plan The project will be constructed in three phases. See Exhibit 9. Phase I shall include commencement of construction of public street frontages along Madison Street and the westernmost section of 54th Avenue prior to the 25th production home and the east/west spine road and westernmost portion of the site. Phase II shall include commencement of construction at the easternmost section of 54th Avenue upon issuance of the 50th building permit or May 31, 2006; whichever comes first. Phase II will also include construction of the central third portion of the site. Phase III will include construction of the easternmost third portion of the site. All off-site improvements are to be constructed as conditioned in the approval of Tentative Tract Map No. 32879 and Specific Plan 2004-074. All areas left vacant during construction will be stabilized using soil stabilization techniques and materials. Prior to issuance of the first certificate of occupancy the project shall complete the parkway landscaping, walls and gates along Madison Street. See Exhibits 18 and 19. As Adopted January 4, 2005 Page 17 of 62 114 Griffin Ranch Specific Plan City of La Quinta Hydrology and Flood Control The site lies in flood Zone C according to Community Panel No. 060245-2300 B dated March 22, 1983. Zone C is an area of minimal flooding; no special protection or measures are required. (Exhibit 10) Grading The site will be graded in a single phase. It is anticipated that there will be a balance of material on the site. The preliminary grading concept for the property shows retention basins located throughout the site for retention of storm flows and nuisance water. The Coachella Valley has been classified by the Environmental Protection Agency (EPA) as a “serious” non-attainment area for PM10 particulate dust. During periods of moderate to heavy wind conditions, wind-blown dust and sand are a concern with grading operations. Because of health concerns, the Environmental Protection Agency has instituted a plan in the valley to curb fugitive dust. Storm Water Pollution Prevention Plan (SWPPP), National Pollution Discharge Elimination System and PM 10 mitigation plans will be adhered to as measures utilized in order to control the wind and water born erosion associated with grading operations. The grading operations shall include adequate provisions for wind and water erosion control during as well as after grading operations have ceased. The details of erosion control shall be included in the project’s Storm Water Pollution Prevention Plan (SWPPP) and PM-10 Plan. As Adopted January 4, 2005 Page 18 of 62 115 Griffin Ranch Specific Plan City of La Quinta Erosion Control The project will comply with the City’s erosion control ordinance. The grading operations shall include adequate provisions for wind and water erosion control during as well as after grading operations have ceased. The details of erosion control shall be included in the project's Storm Water Pollution Prevention Plan (SWPPP) and PM 10 Plan. • Pre Grading --The portions of the site to be graded shall be prewatered to a depth designated by the soils engineer prior to the onset of grading operations. • During Grading -- Once grading has commenced, and until grading has been completed, watering of the site and/or other treatment(s) determined to be appropriate shall be ongoing. • Post Grading -- All disturbed areas shall be treated to prevent erosion for the term that the area will remain undeveloped. Wherever feasible, final landscape and irrigation shall be installed. • On-Site Observer – Throughout the grading portion of the construction, any project with a disturbed surface area of 50 or more acres shall have an On-Site Environmental Observer that: o Is hired by the property owner or developer, and o Has dust control as the sole or primary responsibility, o Has successfully completed the AQMD Coachella Valley Fugitive Dust Control Class and has been issued a Certificate of Completion for the class, and is identified in the approved Fugitive Dust Control Plan as having the authority to immediately employ dust mitigation 24-hours per day, 7 days a week and to ensure compliance with this ordinance, the approved Fugitive Dust Control Plan, AQMD regulations and the Coachella Valley Model Dust Control Ordinance. As Adopted January 4, 2005 Page 19 of 62 116 Griffin Ranch Specific Plan City of La Quinta SWPPP/NPDES/PM 10 Since the Coachella Valley experiences periods of moderate to heavy wind conditions, wind-blown dust and sand is a concern with mass grading operations. Because of health concerns, the Environmental Protection Agency has instituted a plan in the valley to curb excess PM 10 (small particle dust). The City also participates in the National Pollutant Discharge Elimination System program. The City of La Quinta requires SWPPP, NPDES and PM 10 plans to control the wind and water born erosion associated with such grading operations. The project will comply with the City's requirements relative to these programs. UTILITIES Water Plan Coachella Valley Water District (CVWD) provides water service in the City. There is an existing 18” water line located along the west side of Madison Street. There is also an 18” water main along the south side of 54th Avenue (Exhibit 11). Exhibit 12 illustrates the location of proposed water mains throughout the project. The project proposes 3 well sites. Each well site is approximately a half-acre in size. The well sites are located along the northern and eastern boundaries of the project. These well sites will be dedicated to the Coachella Valley Water District. The Coachella Valley Water Management Plan, November 2000, was prepared to address a valley-wide overdraft of the groundwater basin. Water conservation goals within the plan include reducing urban water demand by 10 percent. This project will positively contribute to offsetting the overdraft by incorporating the goals of the management plan and implementing water conservation measures. As Adopted January 4, 2005 Page 20 of 62 117 Griffin Ranch Specific Plan City of La Quinta Measures that promote water conservation include more efficient landscaping, irrigation and utilization of water efficient plumbing fixtures. Sewer Plan Sanitary sewer facilities for La Quinta are provided by Coachella Valley Water District (CVWD). There are no facilities along the northern boundary of the site on 54th Avenue. Along the eastern side of Madison Street is a 33” gravity sewer main with a southerly flow. Likewise, there is an 18” sewer force main east of the gravity sewer main also with a southerly flow. Both gravity and force mains are at the southeast corner of Madison Street and 54th Avenue (See Exhibit 11). Exhibit 13 illustrates the location of proposed sewer service within the development. Eight inch sewer mains will be constructed within private streets throughout the site. The sewer mains will be connected to an off-site connection point located east of the project on Monroe Street. Electrical Plan The Imperial Irrigation District provides electric facilities in La Quinta. There is a 12.5kv power distribution line on the east side of Madison Street. There is also 12.5kv power distribution on the north side of 54th Avenue (See Exhibit 11). At Madison Street and 54th Avenue distribution wires are underground and run west of the site. The City will require the installation of electrical services to be underground if the voltage is less than 34 KV. All electrical service to the residences will be placed underground. As Adopted January 4, 2005 Page 21 of 62 118 Griffin Ranch Specific Plan City of La Quinta Other Utilities The Gas Company provides natural gas services. There is a 4” gas main on the east side of Madison Street and 2 gas mains (8”-high pressure transmission line and a 6” distribution line) on the north side of 54th Avenue. This service is adequate to serve the development. Time Warner Cable provides television cable service to the area. There is service available along the east side of Madison Street and along the north side of 54th Avenue. Verizon will provide telephone service. Based on site visits, there are service connection points along the east side of Madison Street and along the north side of 54th Avenue. Waste Management of the Desert provides waste disposal service. Plans for incorporating recycling facilities will be considered for the development. All appropriate City staff shall review facilities for compliance with all City ordinances.

The property is located on the south side of 54th Avenue and east of Madison Street. 54th Avenue is designated as a Secondary Arterial and Madison Street is designated as a Major Arterial. The project shall dedicate additional right of way to achieve 44’, ultimate right of way along 54th Avenue and additional right of way to achieve 55’, ultimate right of way along Madison Street. Street widening and improvements will be completed as part of this development. Street Cross Sections are shown in Exhibit 14. The main entry at Madison Street will provide the initial opportunity for thematic identification for the community. This entrance shall be staffed by security personnel and will serve as the entry for residents and guests. 54th Avenue will provide 2 secondary entrances to the site and shall be point of access for residents only. The landscape design along the project frontage shall be complementary to landscaping in the area and the goals of the General Plan for Image Corridors. See Exhibits 18 and 19. Madison Street and 54th Avenue are both identified in the La Quinta General Plan as Agrarian Image Corridors. Standards for Image Corridors will be complied with according to the City’s Development Code. The spine road beginning at the main entry on Madison Street to the second round- about will be 55’ wide with a staggered raised median. This spine road will then continue to the easternmost boundary of the site at a width of 41’. As Adopted January 4, 2005 Page 33 of 62 130 Griffin Ranch Specific Plan City of La Quinta The secondary entries on 54th Avenue will have a raised median up to the first intersection of the project. Both secondary entries shall have 41’ wide streets from point of entry to the round-about at the western entrance and to the spine road at the eastern entrance (See Exhibit 28). Pedestrian/Equestrian Griffin Ranch will provide a meandering multi use trail surrounding the site’s perimeter along Madison Street, 54th Avenue and its eastern boundary. These multi purpose trails shall contain walking paths along one side of the spine street, the secondary entrances to the spine street and along the perimeter of the out parcel. The trail will provide access through the community and to the exercise arena located in the southwest portion of the site. There is a private central riding path that will connect to trails on the site perimeter. See Exhibit 16. The retention areas throughout the project will provide opportunity for walking and passive recreation. As Adopted January 4, 2005 Page 34 of 62 131 132 133 134 135 Griffin Ranch Specific Plan City of La Quinta Section V. DESIGN GUIDELINES LANDSCAPE CONCEPTS The proposed Griffin Ranch landscape theme focuses on developing images of an equestrian oriented community set within the desert region that will complement the equestrian essence of the eastern portion of La Quinta. The landscape theme seeks to develop the association by utilizing a trail system and planting concept designed to strengthen the basic fabric and overall theme of the community through the use of specific plant material to define and reinforce the project entries, street patterns and neighborhood identity. Canopy trees, split rail fencing, enhanced desert planting, masonry/stone walls, and lawn create a dynamic landscape statement to this new development. See Exhibits 18 and 19. The proposed plant palette for the common areas is illustrated on Table 1. The Master Plant list shall be approved by the Riverside County Agricultural Commissioner’s Office prior to planting. The generous setback to the proposed perimeter wall allows for a dramatic streetscape, which incorporates multi use trails, smooth stucco walls with iron fixture treatments and decorative view fencing with pilasters at the project entries. Project entries will incorporate a rural equestrian flavor with natural water features, project signage, stone walls and pilasters, rustic vehicular and pedestrian gates. Enhanced paving and accent planting also embrace the landscape theme at the project entry (See Exhibit 25). The interior of the project follows the equestrian theme. Trails of decomposed granite bordered by split rail fencing meander throughout Griffin Ranch. There is a specifically designed area for horse related activities. Trails with accent landscaping flourish in the area used for equestrian riders. Additional open spaces are for passive and active use. Pedestrian trails, free play (lawn), park benches and gazebos occupy the open spaces for non-equestrian use (See Exhibit 20). As Adopted January 4, 2005 Page 39 of 62 136 Griffin Ranch Specific Plan City of La Quinta The equestrian landscape theme at Griffin Ranch will be reinforced by the incorporation of meandering trails throughout the interior and exterior of the project. The decomposed granite trails will be enhanced by split fencing and accent planting to complement the project’s theme. Landscaping for each of the front yards will be designed to embrace the overall community theme utilizing desert appropriate landscape materials that provide shade, seasonal color and texture. Minimum landscape standards as required by the City of La Quinta shall be met as well as complying with irrigation standards (See Exhibits 21, 22, 23 and 24). Landscape and irrigation plans for all developer provided landscape including the project entries, community center, streetscapes, retention areas and perimeter walls shall be prepared by a licensed Landscape Architect. Landscape and irrigation plans shall meet the City of La Quinta’s minimum requirements and be approved and signed by all governing agencies prior to being approved for construction. Project Entry Treatment Madison Street will be the main entry to the project. It will provide initial opportunity for thematic identification for the community. It will be a security staffed gate for use by residents, visitors and guests entering the exiting the project. The landscape design will incorporate a rural equestrian flavor with natural water features, project signage, stone walls and pilasters, rustic vehicular and pedestrian gates. Enhanced paving, willow-like canopy trees and accent planting will complement the landscape theme (See Exhibits 25, 26 and 27). 54th Avenue will provide two secondary entries to the project. Entry is for residents only and will be operated by an entry transponder. The theme will be consistent with the overall project theme which includes vehicular gates, entry walls, signage, enhanced paving and accent planting (See Exhibit 28) As Adopted January 4, 2005 Page 40 of 62 137 Griffin Ranch Specific Plan City of La Quinta Interior streets of the project will carry the equestrian theme. Setbacks for the residential units along the interior collector street and the singled loaded rural street allow for the addition of rails and fencing meandering through the project thereby contributing to the community image (See Exhibits 21, 22, 23 and 24). Landscape Maintenance The common areas will be maintained by the Home Owner’s Association. Trees will be double staked with two inch minimum lodge poles and shall be irrigated with bubblers or emitters. No spray irrigation shall be placed within 18 inches of street curbs. Prior to installation the City shall inspect trees to determine appropriate size. The HOA shall maintain all areas within the project including street and lighting. General Architectural Theme This gated community will include a mixture of semi-custom and custom homes that will include equestrian amenities.

(Project description) -27- 216 XV. a)-g) A traffic Impact Analysis was prepared for the proposed project6• The study analysed both project traffic, and the portion of the requested General Plan Amendment to reduce the street classification of Madison Street from a Major Arterial to a Primary Arterial. The study found that the proposed project will generate approximately 2,900 average daily trips (ADT), of which 223 would be during the morning peak hour, and 292 during the evening peak hour. The study also found that with development of the project site, and surrounding development, studied intersections will operate within the City's established levels of service. In order to assure that project impacts are adequately mitigated, the study includes several mitigation measures, which are summarized below. 1. Madison and A venue 54 shall be improved to their buildout half-width with development of the proposed project. 2. A Class II bikeway and golf cart path shall be located on Madison and A venue 54. 3. A left turn pocket shall be constructed in the median on Madison Street at the project entry to allow for deceleration. 4. Lane geometries shall be as shown on Exhibit 5.1 of the traffic study. 5. The project proponent shall contribute their fair share to signalization of Jefferson Street and Avenue 54, Madison Street and Avenue 54 and Monroe Street and Avenue 54. The proposed project includes a General Plan Amendment which will reduce the road classification, and associated cross-section for Madison Street from its current Major Arterial (6 lanes, divided), to a Primary Arterial (4lanes, divided). The potential impacts associated with this General Plan were studied in a traffic analysis performed separately from the above-referenced project analysis 7• The focus of the analysis was to determine whether Madison Street had been "over-designed" in the General Plan, and whether the 6 lanes were necessary to accommodate existing plus projected traffic at buildout of the General Plan, given the development which has occurred in this area of the City. The analysis found that the approved projects in this area, which are under construction, will generate 22,560 fewer daily trips than that analyzed in the General Plan. The analysis further found that approximately 50% of these trips will travel on Madison Street. Therefore, the potential trips on Madison Street will be reduced from the General Plan assumption of 41,300-43,700 (depending on location) to 30,020 to 32,420 (also depending on location). The capacity of a 6 lane divided roadway is 57,000 daily trips, while the capacity of a 4 lane divided roadway is 38,000 daily trips. Since the actual development affecting Madison Street will reduce the trip generation to 32,420 or less, the Primary Arterial classification and cross section are acceptable to carry the buildout traffic, and the proposed General Plan Amendment will have less than significant impacts on traffic and circulation at General Plan buildout. 6 "Griffm Ranch Specific Plan and Vesting Tentative Map 32879 Traffic Impact Study," prepared by Endo Engineering, September 2004 7 Letter report, dated November 12,2004, by Endo Engineering, titled "Evaluation of the Madison Street Planned Classification." -28- 217 - The project does not include inadequate parking or unsafe designs. The site is located · within the service area of SunLine Transit, and can be served by it. With implementation of these mitigation measures, overall impacts to traffic are expected to be reduced to a less than significant level. -29- 218 219 220 221 222 223 224 225 226 227 228 229 230 231 232 233 234 235 236 237 238 239 240 241 242 243 244 245 246 TTM No. 38083 City of La Quinta Draft Addendum October 2021 Appendix B – CalEEMod Annual Emissions Report – 20 Lots 247 TTM No. 38083 Addendum - 20 Lots Riverside-Salton Sea County, Annual Project Characteristics - This model run applies to the currently mapped condition involving 20 one-acre lots.

20 Lots Riverside-Salton Sea County, Summer Project Characteristics - This model run applies to the currently mapped condition involving 20 one-acre lots. The subdivision of 20 lots into 37 lots will be reflected in a separate model run to determine the quantitative emissions differences. For analysis purposes, the assumed start of construction date is approximately three months from the date of this analysis. Land Use - The current tract map condition includes 20 lots totaling approximately 19.55 acres plus areas for interior road improvements and open space (categorized as other asphalt surfaces). Population estimates are based on the May 2021 CDF household estimate of 2.60 PPH. Construction Phase - Default construction time frames are accepted. No structural demolition phase would be involved. Architectural Coating - SCAQMD Rule 1113 would apply toward the VOC limits in architectural coatings. Area Coating - SCAMQD Rule 1113 would apply toward the VOC content limits in architectural coatings. Construction Off-road Equipment Mitigation - SCAMQD Rule 403/403.1 and LQ Municipal COde would apply through a requirement of dust control measures. This is not a form of mitigation for the Coachella Valley. Mobile Land Use Mitigation - Area Mitigation - SCAQMD Rule 1113 would apply toward the VOC content limits in architectural coatings.

20 Lots Riverside-Salton Sea County, Winter Project Characteristics - This model run applies to the currently mapped condition involving 20 one-acre lots. The subdivision of 20 lots into 37 lots will be reflected in a separate model run to determine the quantitative emissions differences. For analysis purposes, the assumed start of construction date is approximately three months from the date of this analysis. Land Use - The current tract map condition includes 20 lots totaling approximately 19.55 acres plus areas for interior road improvements and open space (categorized as other asphalt surfaces). Population estimates are based on the May 2021 CDF household estimate of 2.60 PPH. Construction Phase - Default construction time frames are accepted. No structural demolition phase would be involved. Architectural Coating - SCAQMD Rule 1113 would apply toward the VOC limits in architectural coatings. Area Coating - SCAMQD Rule 1113 would apply toward the VOC content limits in architectural coatings. Construction Off-road Equipment Mitigation - SCAMQD Rule 403/403.1 and LQ Municipal COde would apply through a requirement of dust control measures. This is not a form of mitigation for the Coachella Valley. Mobile Land Use Mitigation - Area Mitigation - SCAQMD Rule 1113 would apply toward the VOC content limits in architectural coatings.

The Project proposes to subdivide 20 existing 1‐acre residential lots into 37 half‐acre lots within the Griffin Ranch Specific Plan area. The single family lots are located along Seattle Slew Way and Afleet Alex Way, and the existing use is vacant infill land. The 20 lots are currently graded with existing utility and road infrastructure previously installed and are centrally located within the Griffin Ranch Community adjacent to the Merv Griffin Estate. A preliminary site plan for the proposed Project is shown on Exhibit 1. Exhibit 2 depicts the location of the proposed 37 half‐acre lots in relation to the existing roadway network. VEHICLE MILES TRAVELED (VMT) Changes to California Environmental Quality Act (CEQA) Guidelines were adopted in December 2018, which require all lead agencies to adopt VMT as a replacement for automobile delay‐based level of service (LOS) as the new measure for identifying transportation impacts for land use projects. This statewide mandate went into effect July 1, 2020. To aid in this transition, the Governor’s Office of Planning and Research (OPR) released a Technical Advisory on Evaluating Transportation Impacts in CEQA (December of 2018) (Technical Advisory). Planning Commission Resolution 2021‐007 (July 13, 2021) adopts Revision 1 of the City of La Quinta Vehicle Miles Traveled Analysis Policy (City Guidelines). The City Guidelines set forth screening criteria under which Projects are not required to submit detailed VMT analysis. This guidance for determination of non‐significant VMT impact is primarily intended to avoid unnecessary analysis and findings that would be inconsistent with the intent of SB 743. VMT screening criteria for development projects include the following: 420 37 29,181 SF A A N 19°29'04" W 45.69' ∆=00°34'49" R=500.00' 5.06' 36 24,187 SF 35 25,280 SF 34 25,550 SF 33 21,580 SF 32 23,722 SF 31 24,706 SF 30 22,656 SF 29 21,662 SF 28 21,029 SF 27 27,161 SF 26 25,961 SF 25 29,832 SF24 21,416 SF 23 22,680 SF22 20,579 SF21 20,831 SF 20 21,036 SF 19 20,443 SF 18 20,517 SF17 21,111 SF 16 21,602 SF 15 29,787 SF 14 22,397 SF 13 24,437 SF 12 29,176 SF 11 21,755 SF 10 22,316 SF 9 20,878 SF 8 20,320 SF 7 22,062 SF 6 22,435 SF 5 22,355 SF 4 20,926 SF 3 20,060 SF 2 20,057 SF 1 20,027 SF SEATTLE SLEW WAY CANANERO DONALI STREET BOLD RULER WAY R = 1 3 0'R = 500' R = 500' R = 500' R = 500'R = 500' R = 500'R = 500'R = 500'R = 500'R = 500'R = 500'R = 130'R = 300'R = 200'R = 500'R = 500'R = 500'R = 500'R = 300'ALYSHEBA DRIVER = 500'SEATTLE SLEW WAYGIACOMO WAY ALYSHEBA DRIVEME R V G R I F F I N W A Y M E R V G R IFFIN W A Y MERV GRIFFIN WAYSECRETARIATHAFLINGER WAY WAR AVENUE 54 CIRCLE AD M I R A LAFLEET ALEX WAYLOT "A" 96,915 SF 2.23 AC.

Specific examples include Single Family Housing projects less than or equal to 140 Dwelling Units and Multi Family (low rise) Housing projects less than or equal to 200 Dwelling Units.  Affordable Housing with a high percentage of affordable units as determined by the Planning and Engineering departments,  Low VMT Area Screening within an area of development under threshold based upon RIVTAM modeling, and  Redevelopment Projects which replace an existing VMT‐generating land use and do not result in a net overall increase in VMT. PROJECT RESIDENTIAL SCREENING The Project has been reviewed for VMT screening based upon its size as a small project, and no further VMT analysis is needed. Single Family Housing projects less than or equal to 140 Dwelling Units may be presumed to have a less than significant impact absent substantial evidence to the contrary. PROJECT TRIP GENERATION Determining trip generation for a specific project is based upon estimates of the amount of traffic that is expected to be both attracted to and produced by the specific on‐site land use. For this assessment, trip generation rates are based upon data collected by the Institute of Transportation Engineers (ITE) in the Trip Generation Manual, 10th Edition, 2017, and the Trip Generation Manual, 10th Edition Supplement, February 2020. The ITE Land Use (LU) Code 210 and land use description has been utilized to identify the appropriate ITE description of the proposed Project: Trip generation rates used to estimate approved and proposed traffic for the site are shown in Table 1 and trip generation estimates for the currently approved 20 residences are shown in Table 2.

SITE ACCESS AND CIRCULATION CONTEXT The proposed Project will have three access connections to surrounding roadways. At the southwest corner of the site, Seattle Slew Way connects the Project to Merv Griffin Way and outward to Madison Street. Merv Griffin Way provides as a gated access point, serving visitors as well as residents. Northbound right turn and southbound left turn lanes accommodate inbound turning movements at the Madison Street/Merv Griffin Way intersection. At the northwest corner of the site, Donali Street connects the Project to Alysheba Drive and outward to Avenue 54. This is a gated resident‐only access point, with a westbound left turn lane for inbound traffic at the Alysheba Drive/Avenue 54 intersection. At the northeast corner of the site, Bold Ruler Way connects the Project to Merv Griffin Way and outward to Avenue 54. This is also a gated resident‐only access point, with a westbound left turn lane for inbound traffic at the Merv Griffin Way/Avenue 54 intersection. 424 Mr. Jon Myhre CADO La Quinta Estates, LLC November 2, 2021 14041‐02 VMT Screening and Access Assessment Exhibit 2 illustrates the study area intersections located near the proposed Project and identifies the number of through traffic lanes for existing roadways and intersection traffic controls. GENERAL PLAN CIRCULATION ELEMENT Exhibit 3 shows the City of La Quinta Circulation Plan and classifications of adjacent roadways. Madison Street – Madison Street is a north‐south oriented roadway located west of the Project and classified as a 4‐lane divided primary arterial in the City of La Quinta Circulation Plan. Avenue 54 – Avenue 54 is an east‐west oriented roadway located north of the Project and classified as a 4‐lane divided primary arterial in the City of La Quinta Circulation Plan. TRIP DISTRIBUTION AND ASSIGNMENT The trip distribution pattern is heavily influenced by the geographical location of the site, the location of surrounding uses, and the proximity to the regional freeway system. Exhibit 4 displays the estimated Project traffic distribution pattern. Based on the identified Project traffic generation and estimated trip distribution pattern, Project peak hour intersection turning movement volumes are shown on Exhibits 5 and 6 for morning and evening peak hours, respectively. At the Madison Street/Merv Griffin Way (#3) intersection, the approved site residential (20 Dus) adds 1 vehicle during the morning peak hour and 3 vehicles during the evening peak hour to the northbound right turn lane. The proposed Project (37 Dus) contributes an additional 1 vehicle during the morning peak hour and 3 vehicles during the evening peak hour to the northbound right turn lane. At the Madison Street/Merv Griffin Way intersection (#3), the approved site residential (20 Dus) adds 1 vehicle during the morning peak hour and 2 vehicles during the evening peak hour to the southbound left turn lane. The proposed Project (37 Dus) contributes an 2 additional vehicles during the evening peak hour to the southbound left turn lane. At the Alysheba Drive/Avenue 54 (#1) and Merv Griffin Way/Avenue 54 (#2) intersections, the volumes added by the proposed Project (in addition to the approved site residential) at individual turning movements are 2 vehicles or less on all inbound and outbound turns. FINDINGS/CONCLUSIONS Tentative Tract Map 38083 is anticipated to generate approximately 160 more trip‐ends per day when compared to approved residential uses on‐site, with 12 more vehicles per hour during the AM peak hour and 18 more vehicles per hour during the PM peak hour. 425 7 426 8 427 9 428 10 429 Mr. Jon Myhre CADO La Quinta Estates, LLC November 2, 2021 14041‐02 VMT Screening and Access Assessment The Project has been reviewed for VMT screening based upon its size as a small project, and no further VMT analysis is needed. Single Family Housing projects less than or equal to 140 Dwelling Units may be presumed to have a less than significant impact absent substantial evidence to the contrary. The proposed Project will have three access connections to surrounding roadways. Each access point has existing lane geometrics which have been planned to serve buildout of the Griffin Ranch Specific Plan area. Volumes added by the proposed Project (in addition to the approved site residential) at individual turning movements have been reviewed, and the peak hour increases are nominal.

The Tract Map is consistent with the Low Density land use designation as set forth in the General Plan, and as set forth in Specific Plan 2004-074. 2.Consistency with Specific Plan The design and improvement of Tentative Tract Map 38083 is consistent with the La Quinta General Plan, and Specific Plan 2004- 074 with the implementation of recommended conditions of approval to ensure consistency for the homes proposed on the lots created herein. The project density is consistent with the La Quinta General Plan and Specific Plan 2004-074 and is comparable to surrounding residential development. The project is consistent with Government Code section 65863, commonly referred to as the “no Net Loss” requirement and with the Housing Criss Act of 2019, Government Code Section 66300. The additional lots meet density requirements and the policies of these sections. 3.Compliance with CEQA The proposed project will not result in impacts which are individually limited or cumulatively considerable when considering planned or proposed development in the immediate vicinity. Impacts which are individually limited or cumulatively considerable can be mitigated to be less than significant. The design of Tentative Tract Map 38083 and proposed improvements are not likely to cause substantial environmental damage, nor substantially injure fish or wildlife or their habitat. The City Council, on April 17, 2007, adopted a Mitigated Negative Declaration (MND), Environmental Assessment 2006-577, for the Griffin Ranch Specific Plan and Tentative Tract 32879 project via Resolution 2007-035, in compliance with the requirements of the California Environmental Quality Act (CEQA). The Design and Development Department prepared an addendum to the adopted MND as EA2021-0002, pursuant to Section 15164 of CEQA, in that the project is substantially the same as the previously approved project, that conditions have not substantially changed, and that the findings and mitigation measures contained in EA 2006- 577 shall apply to this project. 459 4.Site Design The design of Tentative Tract Map 38083 and type of improvements are not likely to cause serious public health problems, insofar as the project will be required to comply with all laws, standards and requirements associated with sanitary sewer collection, water quality and other public health issues. All roadway improvements, easements, if any and surrounding improvements will be completed to City standards. 5.Landscape Design The proposed project is consistent with the landscaping standards and plant palette and implements the standards for landscaping and aesthetics established in the General Plan and Specific Plan. 460 Source: Esri, Maxar, GeoEye, Earthstar Geographics, CNES/Airbus DS, USDA, USGS, AeroGRID, IGN, and the GIS User Community, Esri, HERE, Garmin, (c) OpenStreetMap contributors, and the GIS user community City of La Quinta Design and Development Department TTM2021-0001Project Area Site Map May 24, 2022 ® Planning Division AVENUE 54 MADISON STREETMONROE STREETDONALI STREET SEATTLE SLEW WAY BOLD RULER WAY ATTACHMENT 4 461 Allen Matkins Leck Gamble Mallory & Natsis LLP Attorneys at Law 1900 Main Street, 5th Floor | Irvine, CA 92614-7321 Telephone: 949.553.1313 | Facsimile: 949.553.8354 www.allenmatkins.com Andrew Lee E-mail: alee@allenmatkins.com Direct Dial: 949.851.5484 File Number: 370221.00005/4871-5305-5003 Los Angeles | Orange County | San Diego | Century City | San Francisco Allen Matkins VIA ELECTRONIC MAIL May 5, 2022 Siji Fernandez, Associate Planner City of La Quinta 78-495 Calle Tampico La Quinta, CA 92253 Email: sfernandez@laquintaca.gov Re: Griffin Ranch Tentative Tract Map 38083: Applicability of State Housing Laws Dear Mr. Fernandez, We represent Capstone Advisors, Inc. (“Capstone”) in connection with its application for the Griffin Ranch Tentative Tract Map 38083 (“Project”), which proposes to subdivide 20 existing residential lots (approximately 24.5 acres), located south of Avenue 54 and midway between Madison Street and Monroe Street in the City of La Quinta (“City”), into 37 residential lots. At staff’s invitation, we submit this letter to explain how the Housing Accountability Act (“HAA,” Government Code, § 65589.5(j)) and portions of the Housing Crisis Act of 2019 (“SB 330,” Government Code, §§ 66300(b), 65905.5) apply to the City’s consideration of the Project. As detailed below, the HAA compels Project approval unless the City is able to make stringent health and safety findings against the Project, and SB 330 prevents the City from imposing subjective design standards and holding more than five hearings on the Project. We trust that this analysis will assist the City and its decisionmakers in reviewing this important Project, and we welcome any questions that staff may have about these state laws. 1.The Housing Accountability Act. The HAA has existed since 1982 and has been strengthened in recent years by pro- development housing legislation. To address the statewide housing shortage, the HAA promotes the approval of housing development projects by limiting the discretion agencies have to deny or impose density-reducing conditions on projects covered by the HAA. (Government Code, § ATTACHMENT 5 462 Allen Matkins Leck Gamble Mallory & Natsis LLP Attorneys at Law Siji Fernandez, Associate Planner May 5, 2022 Page 2 65589.5(a)(1), (2)(K), (j); Honchariw v. County of Stanislaus (2011) 200 Cal.App.4th 1066, 1068, 1074.) The HAA covers any housing project that satisfies two statutory criteria: 1.Constitutes a housing project. The project is a “housing development project” as defined under the HAA, which includes residential-only projects and two-thirds- residential mixed use projects. (Government Code, § 65589.5(h)(2).) 2.Meets objective standards. The project “complies with applicable, objective general plan, zoning, and subdivision standards and criteria, including design review standards, in effect at the time that the application was deemed complete.” (Government Code, § 65589.5(j)(1), emphasis added.) As amended in 2018, a project cannot be “inconsistent with the applicable zoning standards and criteria, and shall not require a rezoning, if the [] project is consistent with the objective general plan standards and criteria but the zoning for the project site is inconsistent with the general plan.” (Government Code, § 65589.5(j)(4).) The HAA further provides three clarifications that strengthen its pro-housing purpose: a.“Compliance” definition. “[C]ompliant . . . with an applicable plan, program, policy, ordinance, standard, requirement or other similar provision” means “there is substantial evidence that would allow a reasonable person to conclude that the [project] is consistent, compliant, or in conformity.” (Government Code, § 65589.5(f)(4).) This means that a city cannot find a project noncompliant so long as there is any substantial evidence that would allow a reasonable person to find the project compliant (the reverse of the typical standard of review where the city’s decision need only be supported by substantial evidence). (California Renters Legal Advocacy and Education Fund v. City of San Mateo (2021) 68 Cal.App.5th 820, 837.) b.“Objective” definition. “[O]bjective” standards and criteria involve “no personal or subjective judgment by a public official and being uniformly verifiable by reference to an external and uniform benchmark or criterion.” (Government Code, § 65589.5(h)(8).) This definition is intended to ensure that projects are measure against only objective standards for purposes of determining coverage under the HAA. (Id., 839.) c.Deemed compliance. If an agency fails to identify an alleged project inconsistency within a certain number of days (30 days for projects with 463 Allen Matkins Leck Gamble Mallory & Natsis LLP Attorneys at Law Siji Fernandez, Associate Planner May 5, 2022 Page 3 fewer than 151 units), the HAA also deems the project compliant by operation of law. (Government Code, § 65589.5(j)(2).) Here, the Project satisfies both criteria for coverage under the HAA. First, the Project constitutes a “housing development project” because it is a residential-only development. Second, the Project is conclusively compliant with the City’s applicable, “objective” standards and criteria for several reasons: •Deemed compliance. The City has not identified in writing any applicable land use regulations for which the Project is noncompliant. Thus, the Project is deemed compliant by operation of law under the HAA. •General Plan consistency. The Project is consistent with the “Low Density Residential” General Plan designation, which authorizes single-family residential at a density of 4 dwelling units per acre (“du/ac”). (Land Use Element p. II-3.) •Specific Plan consistency. The Project is consistent with the use and density of the Griffin Ranch Specific Plan (“Specific Plan”). The Specific Plan allows for a total of 476 units, with a maximum density of 2 du/ac. (Specific Plan, p. 5.) The Project’s addition of 17 units would raise the Specific Plan’s total number of units from 393 to 410, with a density of 1.7 du/ac, both well below the Specific Plan’s allowed maximums. Further, the Project’s 17 additional units, a 4.3% increase, falls well within the Specific Plan’s definition of substantial compliance, which allows a determination of substantial compliance to be made by the Director of Community Development (up to 5%) and by the Planning Commission (up to 10%). (Specific Plan, p. 32; see also General Plan, p. II-24.) •Zoning consistency. The Project is consistent with the applicable “Low Density Residential” base zoning and “Equestrian Overlay,” which authorizes single family residential at up to 4 du/ac. (Municipal Code, § 9.30.030.) Because the Project is covered by the HAA, the City may only deny the Project or impose density-reducing conditions if the City adopted two difficult-to-make “written findings supported by a preponderance of the evidence on the record.” (Government Code, § 65589.5(j)(1), emphasis added.) 1.“The housing development project would have a specific, adverse impact upon the public health or safety” unless denied or made less dense. (Government Code, § 65589.5(j)(1)(A), emphasis added.) “[S]pecific, adverse impact” must be a 464 Allen Matkins Leck Gamble Mallory & Natsis LLP Attorneys at Law Siji Fernandez, Associate Planner May 5, 2022 Page 4 “significant, quantifiable, direct, and unavoidable impact, based on objective, identified written public health or safety standards, policies, or conditions as they existed on the date the application was deemed complete.” (Ibid., emphasis added.) 2.“There is no feasible method to satisfactorily mitigate or avoid the adverse impact” except to disapprove the project or condition it at lower-than-proposed density. (Government Code, § 65589.5(j)(1)(B), emphasis added.) The HAA further defines “feasible” as meaning “capable of being accomplished . . . within a reasonable period of time, taking into account economic, environmental, social, and technological factors.” (Government Code, § 65589.5(h)(1).) These findings are notoriously difficult to make, as the California Legislature has explained that “[i]t is the intent of the Legislature that the conditions that would have a specific, adverse impact upon the public health and safety . . . arise infrequently.” (Government Code, § 65589.5(a)(3), emphasis added.) 2.Senate Bill 330. In 2019, the Legislature passed SB 330, which declares that there is “a statewide housing emergency” in effect until January 1, 2030. (SB 330, SB 8.) Among SB 330’s many provisions, at least two apply to the Project. A. No subjective standards. Generally, SB 330 prohibits “affected” cities like La Quinta from “imposing or enforcing” subjective “design standards” on housing developments where housing is an allowable use. (Government Code, § 66300(b)(1)(C).) Subjective design standards include standards that involve “personal or subjective judgement by a public official” and is not “uniformly verifiable by reference to an external and uniform benchmark or criterion available and knowable by both the development applicant . . . and the public official before submittal of an application.” (Government Code, § 66300(a)(7).) As such, the Project can only be made subject to clearly quantifiable design standards that existed before the application was submitted. B. Five-hearing rule. SB 330 also imposes a five-hearing rule, which requires a city to “approve or disapprove” a housing development application in no more than five public hearings. (Government Code, § 65905.5(a).) Importantly, continued hearings and administrative appeal hearings count toward the five hearing limit.

We trust that the City will find this analysis helpful and instructive in its review of the Project. We look forward to working collaboratively with the City on this Project.

Hayden John Condas 466 PUBLIC HEARING ITEM NO. 3 City of La Quinta PLANNING COMMISSION MEETING: May 24, 2022 STAFF REPORT AGENDA TITLE: ADOPT RESOLUTION TO RECOMMEND CITY COUNCIL APPROVE A STREET NAME CHANGE FOR SILVERROCK WAY AND AHMANSON LANE; CEQA: DESIGN AND DEVELOPMENT DEPARTMENT HAS DETERMINED THE PROJECT IS EXEMPT FROM CEQA UNDER THE PROVISIONS OF SECTION 15061(b)(3) COMMON SENSE RULE; LOCATION: SILVERROCK WAY AND AHMANSON LANE RECOMMENDATION Adopt a resolution recommending City Council approve a street name change for SilverRock Way and Ahmanson Lane to Talus Way and Painted Peak Lane, respectively, subject to the Conditions of Approval and find the project exempt from CEQA pursuant to Section 15061(b)(3), Common Sense Rule. EXECUTIVE SUMMARY •Street Name Change 2022-0002 is proposed by SilverRock Development Company, LLC (Applicant) to change the street names SilverRock Way to Talus Way and Ahmanson Lane to Painted Peak Lane (Attachment 1). •This process is regulated by La Quinta Municipal Code (LQMC) Chapter 14.08 Street Name Changes (Attachment 2). •Applicant is requesting these changes due to the rebranding of the development from SilverRock to Talus (Attachment 3). BACKGROUND/ANALYSIS SilverRock Way and Ahmanson Lane are two streets that run through the Talus Development. SilverRock Way begins at Avenue 52 and runs south and east and connects to Jefferson Street. Ahmanson Lane connects to SilverRock Way and runs south, leading to the current golf clubhouse. The proposed street name changes apply to the entirety of both streets and are being proposed as part of a rebranding for the development. LQMC permits any individual to initiate a street name change, with at least 67% of the owners 467 abutting the street having signed letters of support for this request. The owners abutting these streets include the Applicant and the City of La Quinta. On April 26, 2022, the Planning Commission adopted a resolution of intention to hold a public hearing for the proposed name changes. Following the Planning Commission’s public hearing, Staff followed the public noticing requirements from LQMC Chapter 14.08, which included a notice published in the Desert Sun and posted notices along SilverRock Way and Ahmanson Lane. Staff has reviewed the proposed request and it has met the requirements of LQMC Chapter 14.08. The City Manager also conducted a review of the proposal and recommended the application to move forward for Planning Commission consideration. Following Planning Commission’s recommendation, the proposed request will be considered by the City Council. AGENCY AND PUBLIC REVIEW Public Agency Review The applications were distributed to City staff, including the Riverside County Fire Department. All comments have been addressed and/or added as conditions of approval. ENVIRONMENTAL REVIEW The Design and Development Department has determined that the proposed project is exempt from California Environmental Quality Act (CEQA) under provisions of Section 15061(b)(3). The activity is covered by the common sense exemption that CEQA applies only to projects, which have the potential for causing a significant effect on the environment. In this case, it can be seen with certainty that there is no possibility that the proposal in question may have a significant effect on the environment, therefore the proposal is not subject to CEQA.

Please use proper judgement and caution when opening attachments, clicking links or responding to requests for information. I am opposed to CapStone Advisors request to alter the Tract Map and convert 20 lots into 37 lots. Please review and pass this along to The City Council. Also, please acknowledge receipt of this email. CapStone will likely argue the following points and I have listed my counter for each: 1. Capstone will be unable to sell the lots to a single "Production Builder", since the lots are too large. Counter: Oh, poor Capstone. They knew what they purchased when they purchased it. Capstone already made a great investment decision, purchasing the lots for about $75,000 a piece. They knew these lots were intended for Custom Homes. If CapStone can subdivide the lots, they will probably make an extra $1.5 million to $2 million. This is all about greed. The City Council should not take into account CapStone investment decisions. The lots were intended for Custom Homes. 2. Capstone might talk about the different Production Builders who MIGHT want to purchase the lots and build. Counter: Unless they bring a qualified buyer (Production Builder) to the table who is committed to moving forward, then subdividing the lots FOR A POTENTIAL PRODUCTION BUILDER should not even be considered. 3. Capstone might argue that bringing in a Production Builder will get the project built faster. Counter: As a Griffin Ranch homeowner, I expected a long build out, just like the Madison Club, The Quarry, The Tradition or The Hideaway. I also expect the bump up in home values that Custom Homes will bring to the neighborhood. 4. Capstone might argue that subdividing the lots will make the new 37 homes more similar to the Lennar product that was already built. Counter: Griffin Ranch was envisioned to be a community where the rich lived with the well off who lived with the "just getting by". I love this concept. I do not like having a club with the same socioeconomic make-up throughout. Let's have the diversity in Griffin Ranch that was envisioned. 5. Capstone might try to get Lennar to agree to subdividing the lots. It seems that Lennar still has HOA control over Griffin Ranch. Counter: This would be a bad idea. It seems that some Griffin Ranch Homeowners believe that Lennar was aware that Capstone wanted to subdivide the lots, but failed to disclose this to home buyers that purchased houses adjacent to these lots. Gosh, I expect that there could be years of litigation with these homeowners if the lots are subdivided. 6. Capstone might argue that subdividing would be in support of AB68. Counter: The intent of AB68 was to not include HOAs. However, the law is unclear about this. I expect litigation on this, so stay tuned and I suggest that this not influence your decision. 2 Finally, would you allow me to purchase 3 adjacent lots in the Madison Club or the Quarry and subdivide them into 5 lots? Consider that you might have to allow this based on what you allow in Griffin Ranch.

Please use proper judgement and caution when opening attachments, clicking links or responding to requests for information. Dear Mr. Fernandez, I am writing regarding the above-referenced item for the May 24 meeting of the planning commission. My husband and I live in Griffin Ranch on a lot that backs up to the Capstone land. We did not receive notice of the public meeting on the proposed change to the plan for those lots, and I think we should have, but we have heard from the neighbors (particularly Allen Katz) that the proposal is on the agenda for May 24. We are familiar with the letter that Allen Katz previously sent you regarding this matter, and agree with the points made in his letter. Specifically, we are in favor of the proposed change from 20 1-acre lots to the proposed 37 lots of approximately 1/2 acre, with the intent to have these lots sold to a developer for build-out. Our support for this proposal is contingent upon restricting the building height to 1 story, and the implementation of a temporary construction gate off of Avenue 54. We would like to see the land developed expeditiously to reduce dust and other undesirable effects of having the land undeveloped. Thank you very much for your time and consideration of this. Best regards, Lesa Aylward and Steve Warner La Quinta, CA 92253 1 Tania Flores From:Siji Fernandez Sent:Friday, May 20, 2022 9:43 AM To:Tania Flores Cc:Danny Castro; Cheri Flores; Carlos Flores Subject:FW: Griffin Ranch/ Capstone Matter Support Letter From: Eric Markell Sent: Sunday, May 15, 2022 2:45 PM To: Siji Fernandez <sfernandez@laquintaca.gov> Subject: Griffin Ranch/ Capstone Matter EXTERNAL: This message originated outside of the City of La Quinta. Please use proper judgement and caution when opening attachments, clicking links or responding to requests for information. Dear Mr. Fernandez: I write in support of Capstone’s request for approval of 37 lots. Regrettably, I have not been able to attend public information sessions and cannot attend the May 24 Planning Commission hearing to speak in favor of Capstone's proposal. My wife and I have lived in Griffin Ranch since 2007. I served as an early HOA Board President during the period of workout and restructuring following the departure of TransWest. I was intimately engaged in fashioning the ultimate workout and global settlement of issues among the various parties. The details of that history and settlement are interesting, but not really pertinent to the issues at hand with Capstone. Now that Lennar has finished building out the lots it acquired, the time has come for the Capstone parcel to be developed so that we don’t continue to have a big empty parcel in the middle of our community. I think it now more important than ever as we enter an uncertain economic era that the Capstone plan now before the Commission be approved so that homes consistent with the specific plan can be built by a production builder in a reasonable time frame. If Capstone is forced to keep these as 1-acre custom home lots, buildout could take many repeating the unfortunate situation that has prevailed since 2009. Such an on-going circumstance would be highly detrimental to our community. I understand that Capstone has indicated it would not build two story homes and has agreed to seek approval for a construction entrance on Ave. 54 so that construction traffic will not need to use any of our entrances or our streets. All good steps. Capstone’s plan will be financially beneficial to the community. We will have 37 more homes paying monthly dues with very little, if any, marginal cost to current residents. 2 While some current homeowners will gain new backyard neighbors, that has been true at some time for virtually all 283 current residents . No one has been promised the lack of adjoining neighbors . We need to have these lots built out in a manner that minimizes disruption to our community and to proceed to do so promptly. I encourage the City to move quickly to grant all needed permits to allow Capstone to get its properties in the market and a builder engaged. Sincerely, Eric Markell La Quinta 92253 1 Tania Flores From:Siji Fernandez Sent:Friday, May 20, 2022 9:41 AM To:Tania Flores Cc:Danny Castro; Cheri Flores; Carlos Flores Subject:FW: Capstone project meeting Attachments:Capstone Resident Letter 5-24-2022 FINAL.pdf Opposition Letter From: joshua dimen Sent: Thursday, May 19, 2022 4:54 PM To: Siji Fernandez <sfernandez@laquintaca.gov> Subject: Capstone project meeting EXTERNAL: This message originated outside of the City of La Quinta. Please use proper judgement and caution when opening attachments, clicking links or responding to requests for information. To Those Concerned, I live adjacent to the Capstone property,, . I do not agree with the lot split on the Capstone property. I agree with the Residents Lettere, see attached. I do not know what the final grading will be on the lots that backup to Merv Griffin Way but I do know that one can stand on the Capstone lots and look over the privacy wall onto our property!!!!!!!!!!!!!!!!!!!! I would ask that that Capstone and the City address this issue, either by lowering the lots or raising the wall heights.. Thank You, J. Joshua Dimen Planning Commission City of La Quinta May 24, 2022 RE: TENTATIVE TRACT MAP 38083 (TTM2021-0001) AND ENVIRONMENTAL ASSESSMENT 2021-0002, Cado La Quinta Estates Dear Members of the Commission We represent a group comprised of homeowners and residents of Griffin Ranch (the “Residents”) who own homes immediately adjacent to the property currently at issue, the 20 “Capstone” lots. The purpose of this letter is to formally register our objections to the proposed addendum to the Griffin Ranch Specific Plan that is under consideration by the City of La Quinta Planning Commission. The Residents reserve the right to modify and/or add additional concerns if further information is forthcoming. The Capstone proposal will nearly double the density on this parcel. As currently framed, Capstone proposes to add 85% more homes (37 vs 20 lots) on this 20-acre parcel. For those homeowners with lots immediately adjacent to the proposed project, a change in the density of this magnitude will significantly impact our quality of life. 1. Due Process. The matter noted above was first brought to the attention of the homeowners at a meeting of the Griffin Ranch HOA in late January 2022. The response from homeowners at that meeting was one of shock. Capstone brought the matter to the Planning commission three days later (January 25, 2022) at which time they asked that the commission delay acting and stated their intention to engage in constructive discussions with the homeowners. While some discussions have been undertaken, they cannot be characterized as being constructive. The CEO of Capstone, Alex Zikakis, held one in person meeting with representatives of the Residents. A number of informal emails and telephone calls with Mr. Zukakis followed this meeting. The Residents subsequently submitted a written list of their concerns to Capstone and Capstone agreed to no two-story homes and to create an ingress and egress access though an existing wall on 54th Street so as to avoid construction traffic on Alysheba and Merv Griffin Way. These two concessions have not been reduced to writing. And throughout this process, while always cordial, it was brutally evident that Capstone did not feel that they had any obligation to agree to any accommodation of any of the Residents material concerns. Capstone arranged with the Griffin Ranch HOA board to hold a “town hall” for all the residents of Griffin Ranch. No new or useful information was presented and no dialogue regarding the Residents’ concerns was engaged. 2. Informed Acquisition By Capstone. Capstone reported that they have owned the property in question for more than 10 years and that they were fully aware of the development plan for the sites as 20 one-acre custom home sites at the time of their purchase. Of note is the fact that in 2016, Capstone executed and recorded an annexation of the entire parcel to the Griffin Ranch development. The current effort to restructure the property lines of the 20 lots in question is an obvious effort to generate greater valuation from the property. Capstone knew what they were investing in when they bought the property. The Residents, who only just recently purchased their homes in 2021, did so with the belief that the adjacent lots were 20, roughly square, one acre lots – not 37 long rectangular half acres lots, 3. Reliance on the Tract Map. The homeowners who have acquired these homes likewise also did so with material reliance on the city approved plan for land use behind their new homes. There is no reason why the city should now change what the Residents reasonably relied upon. This proposal materially alters that plan and fundamentally changes the nature of the homesites. Lennar, in their sales presentations to the homeowners made repeated reference to that fact that these very large one-acre custom home sites would afford the Residents unusual privacy and support future value. 4. Required Consent The CC&R’s for Griffin Ranch require that the “Declarant” (Lennar Corporation) must consent to any changes to the development plan for the entire neighborhood and a “Neighborhood Builder” (e.g. Capstone) may NOT make modifications without Lennar’s consent. Currently, Lennar is still in control of the Griffin Ranch HOA and holds 60% of the board seats. Lennar is therefore in sole control of the HOA and has sole authority over the entire project and fiduciary responsibility to the homeowners. Lennar, as noted above, made clear representations to the Residents with respect to these 20 one-acre lots behind their homes to be built as one-acre custom homes. Lennar has not as of this date, to the best of our knowledge, violated its commitments and disclosures to the Residents by consenting to the addendum to the Griffin Ranch Specific Plan as currently proposed by Capstone. Without Lennar’s consent, Capstone’s application fails to meet its contractual obligations under the CC&R’s. 5. Implications for common services including access, egress, sewer, water, and other infrastructure Capstone reported at the January HOA Meeting that they had conducted environmental impact studies and reviewed these with the city. The residents have received no information to support Capstone assertions that studies have been reviewed with the City. None of these documents have been disclosed. Nor have the Residents seen or been given an opportunity to review any reports from the City sanitation offices with regard to sewer capacity, drainage and supporting infrastructure. The residents have not been provided with any information with respect to fire danger mitigation, provision of emergency egress and fire suppression requirements. The Residents have material concerns with respect to traffic flow in this area not only during normal times but also during seasonal stresses occasioned by the Coachella and Stagecoach festivals. 6. Implications for Construction Construction traffic must be provided direct access to the Capstone property without use of any Griffin Ranch gates or finished roads. Merv Griffin Way was recently resurfaced. Nearly doubling the number of homes to be built will dramatically increase the amount of heavy equipment traffic that can currently only reach the Capstone Property by accessing Merv Griffin Way and for that matter, Alysheba. Capstone has yet to present any written solution for this problem. 7. Inconsistency with the Griffin Ranch Development Capstone has also asserted that the new size of the lots will be “consistent” with the typical lot already in Griffin Ranch. This is simply not true. All the lots immediately adjoining the tract in question are roughly square and sized at about ½ acre. Other lots in Griffin Ranch are almost all essentially square even if smaller and there are some that are as large as roughly ¾ acre. The Residents carefully reviewed all lots in Griffin Ranch and could not identify any lot in Griffin Ranch with similar characteristics to these proposed lots even in the oldest part of the development. These proposed long and narrow lots will result in long and narrow homes that are also inconsistent with any other design in Griffin Ranch. Capstone (Cado La Quinta) also had access to and knowledge of the approved plan when it made its decisions to invest in these 20 one-acre lots and to quietly hold that investment for over a decade. Capstone waited until the very last of the primary part of Griffin Ranch was completed before coming forward to pursue this addendum to the Griffin Ranch Specific Plan. There is no sound reason why Capstone should now expect to be able to depart from that plan. There is no compelling reason why those who have relied on these long-standing public and approved documents should be penalized nor any reason why Capstone should be granted a change in the approved Specific Plan. The Planning Commission should know that we have collectively and repeatedly asked Capstone to engage in discussions with us to seek a solution acceptable to all concerned. Instead, Capstone has suggested that they would only be willing to enter into a declarant agreement with Lennar to limit homes to single story and route construction traffic through a specific construction entrance directly to Avenue 54. What We request When balancing the interests of all concerned there is simply no reason to approve this proposed addendum to the Griffin Ranch Specific Plan other than to allow Capstone to increase their profits. And to do so, in our opinion, would be to the detriment of the Residents and the Griffin Ranch community. This is not a new development, rather it has been underway for nearly 20 years and is nearly finished. A change of this magnitude at this late stage is neither wise, fair nor appropriate. The Residents are not unreasonable Should the Planning Commission choose to move forward, the Residents respectfully request that the commission impose the following restrictions: - That Capstone may not create more than 28 home sites (a 40% increase) subject to further public comment - That no two-story homes be permitted - That the homes must comply with all design and use requirements of the recorded Griffin Ranch CC&R’s - That a separate construction traffic entrance be created directly into the tract with no construction traffic permitted on Alysheba or Merv Griffin Way.

My partner and I have lived in Griffin Ranch since 2008. The original developer was Transwest which was owned by the McComic family. In 2009, the real estate market tanked. Transwest halted work, leaving us with unfinished streets, over 200 vacant lots and several half-finished homes. Transwest left without starting the clubhouse and other recreational facilities that we had been promised. The bank that financed the project became insolvent and was taken over by the FDIC which then sold the unfinished development to a hedge fund. I went on the HOA Board at that time. We brought a lawsuit to enforce the completion bond for the clubhouse. In 2012 we reached a global settlement. A new investor-owned entity, IOTA, was formed to buy the empty lots and take over the project. IOTA selected Lennar to be the builder. The settlement provided funding to build the clubhouse and recreational facilities. In 2015, Lennar bought the remaining unimproved lots from IOTA. Lennar has now completed its last houses. A separate McComic entity had owned the custom-home parcel around the old Merv Griffin estate, but they sold the parcel in 2009. IOTA and Lennar never acquired this land. It was purchased by Capstone in 2010. 2 Now that Lennar has finished building out the lots it acquired, the time has come for the Capstone parcel to be developed so that we don’t end up with a big empty parcel in the middle of our community. The Capstone plan now before the Commission is designed to get homes built by a production builder in a reasonable time frame. If Capstone is forced to keep these as 1-acre custom home lots, buildout could take 5, 10 or more years. The long-term uncertainty of empty one-acre lots and not knowing what mega-mansions might be built on those lots will be detrimental to our community. Custom homes could be two stories under the Specific Plan. Two-story homes, of varied architectural style, would destroy the visual cohesiveness of our community. And two-story homes will impact the privacy of neighboring homes far more than the one-story homes that would be built under the Capstone plan. Capstone has agreed to seek approval for a construction entrance on Ave. 54 so that construction traffic will not need to use any of our entrances or our streets. In contrast, if Capstone is forced to stick with custom home lots, then each of 20 builders, and each of their numerous subcontractors, would have the right under the CC&R’s to use our gates and our streets for construction access. It will be very disruptive to residents and would damage our streets, many of which are brand new. With no long-term connection to our community, each custom builder and their contractors will have little incentive to be good neighbors during the construction process. Capstone’s plan will be financially beneficial to the community. We will have 37 more homes paying monthly dues. And there will be only a narrow border of common area landscaping that the HOA will need to maintain. So there will be a net financial benefit to the HOA. Adding 17 homes does not impose a significant additional burden on our facilities. We now have 283 homes, and would have 303 if 20 custom homes were built. We’ll have 320 homes if 37 homes are built. 320 vs 303. It’s only a 5% increase. I am a regular user of the fitness facility and can attest that it is never overcrowded. Some homeowners who have back yards adjoining the Capstone property may well prefer to have the Capstone property remain undeveloped for the indefinite future. They may prefer an empty lot rather than have any back yard neighbors. I can’t fault them for that. But that’s not in the best interests of our community. We need to have these lots built out in a manner that minimizes disruption to our community. The Capstone plan will hopefully accomplish this and it should be approved.

TO THE MEMBERS OF THE LA QUINTA PLANNING COMMISSION Regarding Item #2 on the agenda of the May 24, 2022 Commission meeting, Capstone/Griffin Ranch. I have recently been elected to the Griffin Ranch HOA Board of Director While I am not writing on behalf of the Board, I am writing on behalf of the myself and a number of concerned Griffin Ranch homeowners. While Capstone has made two presentations to the Griffin Ranch community, they have not engaged in meaningful discussions with the community Therefore, I re pectfully reque t that the vote on approval of their change to the approved Specific Plan be continued for 90 days until Capstone and leadership of the community have had an opportunity to reconcile the issues surrounding that development and, in particular, the impacts proposed changes will have on our community. Concern 1 The City approved plan change to the original Specific Plan that allowed con truction of a Club Hou e approximately half the size of the original development. That clubhouse is now incapable of accommodating the number of residents desiring to attend major events. Adding more homes, particularly more than the 20 homes already approved will exacerbate that problem. 2. Homeowners of property adjacent to the Capstone property have legitimate concerns on density, layout and set back i ue 3 There i no recreation area propo ed for the Cap tone development That hould be a requirement 4 While Cap tone executive have committed to creating a eparate con truction ingre and egre on Seattle Slew Way, I believe that should be a condition of approval. Additionally, there should be no two story homes which would be inconsistent with the Lennar built homes and they should be required to adhere to all CC&R’s from the date of approval of their project. I/we want to ee the Cap tone property developed, but in a way that i ocially re pon ible and with con ideration to the impacts on other homeowners in our community. Respectfully, James J. Kilpatrick La Quinta, CA 92253 1 Tania Flores From:David Wheeler Sent:Monday, May 23, 2022 4:48 PM To:Siji Fernandez Cc:Tania Flores Subject:May 24, 2022 Planning Commission meeting // Capstone/Griffin Ranch // Agenda Item No. 2 EXTERNAL: This message originated outside of the City of La Quinta. Please use proper judgement and caution when opening attachments, clicking links or responding to requests for information. Dear Mr. Fernandez, please include this email in the package Staff presents to the Commission. TO THE MEMBERS OF THE LA QUINTA PLANNING COMMISSION: Recently, the owner of the Capstone property met with the Griffin Ranch community. Based upon the representations Capstone made at that meeting, we do not oppose the increase in the Capstone lots from 20 to 37. However, we believe conditions should be placed on approval of the increase. Capstone’s application has raised significant issues, and Capstone knew or should have known that there would be such issues. Capstone should have come to the Griffin Ranch community long ago and addressed these issues forthrightly, but it chose not to do so. Therefore, it is our position that Capstone’s application should be continued by at least 90 days so that at least two significant issues can be addressed. First, the Clubhouse and recreational facilities at Griffin Ranch are already overburdened. At peak times, pickleball players sometimes must wait for a court. Equally important, the Clubhouse itself is too small to hold opening, closing and other large parties inside. Recently, attendance at events has been limited to the first to sign up. When we bought our home, we were told that 20 homes would be built on the Capstone property, and we believe this is what other purchasers of homes were told. We would prefer that the Capstone development be limited to the 20 homes we were told about. However, Capstone has presented arguments why developing homes on 20 one-acre custom lots on its property is not commercially feasible and is no longer appropriate given the plans for development of portions of the Merv Griffin Estate property with much smaller lots. 2 Nonetheless, adding 17 homes creates an additional burden on community facilities that homeowners were not told about and that they did not assume. This is particularly important because (a) the development that was originally planned at Griffin Ranch almost twenty years ago did not occur, (b) the clubhouse that was built is much smaller than the clubhouse that was originally planned, and (c) Capstone did not contribute to the cost of the construction of the Clubhouse or the recreational facilities. If Capstone wishes to develop 37 lots, it should be required to dedicate at least one lot for additional recreational facilities, and it should also be required to make a contribution to the cost of the Clubhouse and recreational facilities. Second, a number of homeowners who have homes bordering on the Capstone property have legitimate concerns about setbacks, increased density, and other matters. We understand that they are making submissions to the Commission addressing those concerns. Debbie and David Wheeler La Quinta CA 92253
