La Quinta City Council
January 20, 2026

The City's General Plan includes the following policies to manage and reduce noise impacts from future development:
• Policy N-1.1: Noise standards in the City shall be consistent with the Community Noise and Land Use Compatibility scale described in this Element.
• Policy N-1.2: New residential development located adjacent to any roadway identified in Table IV-4 as having a build out noise level in excess of 65 dBA shall continue to be required to submit a noise impact analysis in conjunction with the first Planning Department application, which demonstrates compliance with the City’s noise standards. • Policy N-1.3: New non-residential development located adjacent to existing residential development, sensitive receptors or residentially designated land, shall be required to submit a noise impact analysis in conjunction with the first Planning Department application, which 377 Return to Agenda Link

City of La Quinta Highway 111 Corridor Specific Plan 3-86 demonstrates that it will not significantly impact the adjacent residential development or residential land.
• Policy N-1.4: All Mixed Use projects shall be required to submit a noise impact analysis in conjunction with the first Planning Department application, which demonstrates compliance with the City’s noise standards.
• Policy N-1.5: All noise impact analysis will include, at a minimum, short-term construction noise and noise generated by the daily operation of the project at build out. • Policy N-1.6: The City may require remedial noise control plans and/or improvements for areas experiencing noise in excess of adopted City standards. • Policy N-1.7: Noise impact analysis shall be included in all City Capital Improvement Plan (CIP) and developer-required roadway widening projects to demonstrate compliance with City noise standards.
• Policy N-1.8: Maintain a truck route plan restricting truck travel to arterial roadways. a) Result in generation of a substantial temporary or permanent increase in ambient noise levels in the vicinity of the project in excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies? Less than Significant Impact with Mitigation Incorporated: In the City, traffic noise - especially from heavy trucks - is the most prevalent source of noise, with additional noise coming from commercial activities and daily operations. Section 9.100.210 of the La Quinta Municipal Code sets noise standards, allowing 60 dBA from 7 AM to 10 PM and 50 dBA from 10 PM to 7 AM for sensitive uses, and 75 dBA and 65 dBA, respectively, for nonresidential areas. Construction projects often use heavy equipment that generates noise between 68 dBA and over 100 dBA at 50 feet, with levels decreasing by about 6 dBA for each doubling of distance. However, heavy equipment near sensitive areas can still cause brief periods of excessive noise. To address this, the City’s noise ordinance limits construction activities during evenings, weekends, and holidays. To mitigate construction-related noise impacts associated with the Highway 111 Corridor Specific Plan, projects within the Specific Plan area shall implement NOI-1. Additionally, developments near sensitive receptors would include a construction noise analysis.

The addition of mixed use and residential areas along Highway 111 is intended to create a vibrant, interconnected, and pedestrian-friendly downtown. Future development, as outlined by the Specific Plan may temporarily generate construction noise as well as increase longer-term operational noise along the corridor Noise levels are anticipated to be compatible with the urban environment. For future developments along the Highway 111 Corridor, the City may require a noise impact study. Based on this study, projects may need to include noise mitigation measures as per General Plan policies NS-1.1 through NS-1.8, ensuring that noise levels remain acceptable and impacts are minimal. Future development would follow the City’s Municipal Code and General Plan policies to ensure traffic noise remains within acceptable levels, preventing exposure beyond these standards. As such, impacts are expected to be less than significant.

Mitigation Measures: NOI-1.
b) Result in generation of excessive groundborne vibration or noise levels? Less Than Significant Impact: None of the permitted uses in the proposed Specific Plan area involve excessive vibration or groundborne noise. However, construction of future developments in the area may temporarily cause short-term noise or vibration impacts. The City's General Plan notes that groundborne vibration primarily comes from construction equipment, train activity, and heavy truck traffic. However, 378 Return to Agenda Link
Environmental Analysis – Noise
City of La Quinta Highway 111 Corridor Specific Plan 3-87 unlike noise, there is no standardized method for measuring vibration. In the City, most vibration is caused by construction and heavy trucks, as there are no train tracks within the City or its surrounding areas. Over time, the introduction of new vibration sources is not anticipated. While construction equipment and heavy trucks may cause brief, localized vibrations, these are not expected to have a significant impact on the City.

The implementation of the Specific Plan would not directly increase groundborne vibration or noise levels.

Future development under the Plan would require additional CEQA review and noise/vibration analysis. As such, impacts related to excessive groundborne vibration or noise levels are anticipated to be less than significant.

Mitigation Measures: No mitigation measures required.
c) For a project located within the vicinity of a private airstrip or an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project expose people residing or working in the project area to excessive noise levels?
No Impact: The Bermuda Dunes Airport is approximately 2.7 miles north of the study area and the Jacqueline Cochran Regional Airport is situated in the community of Thermal approximately 8 miles southeast of the Project area. The Bermuda Dunes Airport is a public use airport that is privately owned.

The Jacqueline Cochran Regional Airport is also a public use airport and primarily handle business and private air traffic. As airport activity is expected to grow in the future, noise impacts would vary depending on the runway used. One runway, aligned north-south, primarily generates noise to the north and south.

The other runway, oriented northwest-southeast, produces noise mainly around the immediate area.

Consequently, noise from the airport is not expected to impact areas west of Harrison Street, about 7 miles southeast of the Specific Plan limits. Any future development along the Highway 111 Corridor would not be affected by this airport as the Specific Plan area is northwest of this airport. Due to the distance from the airport, the Specific Plan area is unlikely to experience excessive noise from airport operations. No impacts would occur.

Mitigation Measures: No mitigation measures required.

Noise Mitigation Measures
• NOI-1: Noise Reduction
All construction activities shall adhere to the City Construction Hours/Quality Assurance Program for designated construction hours, and equipment with internal combustion engines must be equipped with manufacturer-recommended mufflers. Future development projects shall use noise-reducing paving materials during temporary construction activities, such as open-grade asphalt, for all road surfacing, as feasible.

Currently, the City of La Quinta has a vibrant population (estimated at 40,000 residents), with expectations of growth in the years ahead. As the City continues to attract new residents and businesses, there is a pressing need to develop its areas thoughtfully, particularly focusing on sustainable practices. The Highway 111 Corridor, a central hub for commercial activities, is slated for development that integrates mixed-use spaces and fosters walkability and connectivity. This approach aims to streamline City functions, ensuring that as the City expands, it does so in a sustainable and community-oriented manner that enhances the overall quality of life for its residents.

Through the implementation of the Specific Plan, the Highway 111 Corridor would integrate residential development and mixed-uses alongside its current commercial development, promoting a community design that prioritizes pedestrians and cyclists to enhance overall quality of life and mobility throughout the City.

The City must participate in regional efforts mandated by Senate Bill 375 (SB 375), a California state law focused on curbing urban sprawl, promoting sustainable community planning, and cutting down on vehicle trips and air emissions to reduce greenhouse gases. This law mandates "Sustainable Community Strategies" crafted by the Southern California Association of Governments (SCAG), aiming to promote concentrated development, mixed-use areas near job centers, bus routes, and commercial services (City of La Quinta, 2022).

The proposed Project's Development Moderate Scenario is projected to introduce around 1,000 residential units (equivalent to 1,464,000 GSF) and approximately 339,000 GSF of additional retail, commercial, hotel, restaurant, and civic spaces within the Specific Plan area. In contrast, the Specific Plan's Development Max Scenario aims to incorporate roughly 1,600 residential units (totaling 1,837,000 GSF) and about 526,000 GSF of new retail, commercial, hotel, restaurant, and civic spaces into the area. The Development Moderate Scenario estimates a total development of approximately 1,803,000 GSF, while the Development Max Scenario estimates approximately 2,363,000 GSF – a 31.08% increase in developed area along the Highway 111 Corridor. See Figure 1-3 and Figure 1-4 for more information on development area scenarios and land use build out.

Environmental Analysis – Population and Housing
City of La Quinta Highway 111 Corridor Specific Plan 3-89 a) Induce substantial unplanned population growth in an area, either directly (for example, by proposing new homes and businesses) or indirectly (for example, through extension of roads or other infrastructure)?
Less than Significant Impact: The Specific Plan is intended to provide guidance for the organized development and redevelopment of local infrastructure, businesses, and housing along the Highway 111 Corridor. The City aims to create a cohesive blueprint that integrates shopping, living, working, and recreational spaces in one interconnected area. This space would be accessible through Highway 111, the CV Link, and other multi-use paths. The implementation of the Specific Plan is expected to take place gradually over a period of 20 to 25 years. If economically feasible, the completion of Specific Plan build out could result in an additional residential area from 1,464,000 GSF (Development Moderate Scenario) to 1,837,000 GSF (Development Max Scenario) for the Highway 111 Corridor. Moreover, including residential units along the Highway 111 Corridor would create housing opportunities in an area traditionally focused on commercial activities, thereby introducing a more diverse and beneficial mix of uses in the region in a sustainable manner.

As a guidance document, the proposed Specific Plan does not contain detailed designs or specific proposals for particular sites, nor does it provide authorization for any development activities. Nevertheless, potential enhancements within the Specific Plan area could involve the construction of new residential or commercial properties, which may result in a direct or indirect population increase within the designated area. Even if all the residential, commercial, and hotel developments envisioned by the Specific Plan were built, the population growth associated with these developments would occur gradually over an extended period. Furthermore, any future improvements would likely reference and tier off of this CEQA document to evaluate potential impacts related to population growth and development. Therefore, the overall impact on population growth would be deemed less than significant.

Mitigation Measures: No mitigation measures required.
b) Displace substantial numbers of existing people or housing, necessitating the construction of replacement housing elsewhere?
Less than Significant Impact: The proposed Project area along the Highway 111 Corridor is currently zoned primarily for commercial purposes, featuring shopping centers, restaurants, and office spaces. This area has traditionally focused on big box retail with limited residential options. However, the proposed Project aims to increase residential opportunities in alignment with the La Quinta General Plan and Municipal Code. This approach ensures that the Specific Plan would not displace individuals or housing but rather diversify land use to accommodate additional residential development. Given its inefficient use of space and sprawling commercial developments, the Highway 111 Corridor presents an opportunity to improve its walkability and accessibility. The proposed development outlined in the Specific Plan seeks to revitalize the area by drawing more people and optimizing land use in the region, thereby encouraging a more dynamic and accessible environment. By promoting land use types that support residential growth, the Specific Plan mitigates potential significant impacts on population resulting from the proposed development scenarios and improvements along the Highway 111 Corridor. As such, impacts are anticipated to be less than significant.

Mitigation Measures: No mitigation measures required.

Highway 111 serves as a crucial arterial corridor in the City of La Quinta, facilitating essential routes for emergency services and access to public facilities. It not only connects the northern residential neighborhoods with the bustling southern commercial core but also links other residences, schools, and public facilities along its path. Highway 111 intersects with Washington Street, a prominent north-south thoroughfare within the City that links Highway 111 to the Civic Center Campus located to the south. Public facilities encompass City-owned buildings such as City Hall, the Library, and the Senior Center, which collectively form the Civic Center Campus. Additionally, facilities include schools operated by either the Desert Sands Unified School District or the Coachella Valley Unified School District. The City is supported by the Riverside County Fire Department (RCFD), offering fire protection and emergency medical services not only to the City itself but also to neighboring areas within Riverside County. Law enforcement services and the protection of public safety are overseen by the Riverside County Sheriff's Department (RCSD).

The City features 12 parks that offer a variety of recreational activities and amenities, ensuring both residents and visitors have numerous opportunities for outdoor enjoyment and community gatherings (City of La Quinta, 2022). However, there are no parks located within the Specific Plan area. Most of the City's parks and greenspaces are located outside the Highway 111 Corridor; this route acts as a vital connection, allowing residents to seamlessly access these recreational areas beyond the urban commercial core.

Residents of the City currently enjoy access to 72 acres of parks, 146.75 acres of nature preserves with recreational parkland, and 845 acres of regional parks. The City also has joint use agreements with Desert Sands, neighboring cities, and the Desert Recreation District for the use of additional recreation facilities (City of La Quinta, 2022).

The proposed development under this Specific Plan seeks to enhance connectivity throughout the City, transforming Highway 111 from a principally vehicular thoroughfare into a unified, integrated corridor for active transportation. The emphasis would be on fostering mixed-use developments that cater to pedestrian and multimodal transportation needs, thereby creating a cohesive urban environment. This approach aims 382 Return to Agenda Link

City of La Quinta Highway 111 Corridor Specific Plan 3-91 to blend residential, commercial, and recreational spaces seamlessly, promoting a more vibrant and accessible cityscape.

As development progresses along the Highway 111 Corridor, there may be heightened demand for fire protection, emergency services, and public facilities, including parks. This growth could necessitate the hiring of additional staff and the construction of new facilities to adequately support the expanding corridor.

The General Plan's Emergency Services Element, Public Facilities Element, and Parks and Recreation Element specifically address future requirements for fire, emergency response, and public amenities. a) Would the project result in substantial adverse physical impacts associated with the provision of new or physically altered governmental facilities, need for new or physically altered governmental facilities, the construction of which could cause significant environmental impacts, in order to maintain acceptable service ratios, response times or other performance objectives for public services?
Less Than Significant Impact: Possible improvements within the designated Specific Plan area might entail the development of new or expanded residential or commercial properties, potentially leading to a population increase, either directly or indirectly. This may increase the demand for the following public services:

1. Fire Protection and Emergency Services: The proposed Project is aimed at promoting development, which could lead to a rise in demand for fire protection services. As a result, there would likely be a need for both additional personnel and new facilities to accommodate the anticipated growth in the Specific Plan area. The City’s General Plan acknowledges the need for expanded fire protection services to meet demands associated with future population growth.

Although strategic placement of fire stations is present, additional fire stations would likely be needed in areas where growth occurs (City of La Quinta, 2022). Future development under the Specific Plan could increase the need for additional fire protection and emergency services. Impacts are anticipated to be less than significant as future development would be required to pay Development Impact Fees (DIF) to help offset impacts to fire and emergency services and would be required to be consistent with the following policies from the City’s General Plan:
• Policy ES-1.1: The City shall continue to work with the Riverside County Fire Department to accurately forecast future needs and provide adequate and timely expansion of services and facilities based on service capabilities and response times. − Program ES-1.1a: Maintain the Fire Facilities component of the City’s Development Impact Fee to assure that new development pays its fair share of future fire stations. • Policy ES-1.2: New Development proposals shall continue to be routed to the Fire Department to assure that project access and design provide for maximum fire and life safety. • Program ES-1.8a: Periodically review and update the Emergency Operations Plan to address the City’s growth in population and built environment, as well as new emergency response techniques.

2. Police Protection: The development proposed in the Specific Plan could act as a catalyst for growth, potentially increasing the demand for police protection services. Therefore, there may be a necessity for additional personnel and the construction of new police facilities to adequately accommodate the growth along the Highway 111 Corridor. The City’s General Plan acknowledges the potential need for increased police protection services to accommodate population growth. The City follows the standard of one police officer per 1,000 residents (City of La Quinta, 2022). Should 383 Return to Agenda Link
Environmental Analysis – Public Services
City of La Quinta Highway 111 Corridor Specific Plan 3-92 future development prompted by this Specific Plan result in a rise in residential units and population, additional officers may be necessary. Impacts on police protection services are expected to be less than significant as future development would be required to pay DIF fees to help offset impacts to police services and development would be required to be consistent with the following policies from the City’s General Plan:
• Policy ES-1.5: The City shall continue to work with the Riverside County Sheriff’s Department to accurately forecast future needs and provide adequate and timely expansion of services and facilities.
• Policy ES-1.6: New development proposals shall continue to be routed to the Police Department to assure that project access and design provide for defensible space and maximum crime prevention while maintaining City design standards and codes.

3. Schools: Local schools are managed by two public school districts that offer education from kindergarten through Grade 12: the Desert Sands Unified School District and the Coachella Valley Unified School District (City of La Quinta, 2022). The Desert Sands Unified School District currently serves the corridor area. Although there are no public schools from these districts in the Specific Plan area, population growth, including an increase in school age children, is possible with development facilitated by the Specific Plan. The anticipated population growth could increase the demand for school services and potentially create the need for new or physically altered school facilities. Schools could be built on properties near the Highway 111 Corridor or on sites within the corridor that are served by existing infrastructure. Future development within the corridor area would be required to pay school fees, in the amount set at the time of building permit issuance, to offset any impacts created by additional residential units. As such, impacts on schools are anticipated to be less than significant.

The Specific Plan would be consistent with the following policies from the City’s General Plan:
• Policy PF-1.6: The City shall coordinate with the Desert Sands and Coachella Valley Unified School Districts and encourage the Districts to plan for and construct new schools to meet demand.

4. Parks: No parks are located within the Specific Plan area; however, the CV Link is a multi-modal trail system that runs along the Whitewater River at the north boundary of the corridor area and would be available for new residents and patrons in the corridor. It is assumed that population growth would result in an increase in demand for neighborhood and regional parks and other recreational facilities. This Specific Plan supports the creation of additional recreational spaces and pocket parks along the Highway 111 Corridor and a trail connector along the northern side of Highway 111 to connect with the CV Link. The proposed development outlined by this Specific Plan would enhance and potentially expand recreational facilities within the City without causing impacts beyond those anticipated by the City’s General Plan. The City’s General Plan includes goals and policies to maintain current parks and facilities and to acquire additional parkland for future population growth, as listed below. Section 3.16, Recreation, provides a more detailed overview of the City's recreational assets.

The Specific Plan would be consistent with the following policies from the City’s General Plan:
• Goal PR-1: A comprehensive system of parks and recreation facilities and services that meet the active and passive needs of all residents and visitors. • Policy PR-1.1 Expand or modify community services to meet the health, well-being, and recreational needs of the community.
384 Return to Agenda Link
Environmental Analysis – Public Services
City of La Quinta Highway 111 Corridor Specific Plan 3-93 • Policy PR-1.2: Continue to provide a minimum standard of 5 acres of parkland for every 1,000 residents.
• Policy PR-1.3: Identify all viable financing mechanisms for the funding of construction, maintenance, and operation of parks and recreational facilities. • Policy PR-1.4: The design and construction of parks and recreational facilities shall comply with all the development standards that apply to privately constructed facilities. • Policy PR-1.5: Coordinate with partner agencies and neighboring communities to expand recreational opportunities and access to recreational facilities. • Policy PR-1.6: Encourage patterns of development that promote safe pedestrian and bicycle access to schools, public parks, and recreational areas. • Policy PR-1.7: Identify opportunities to integrate public health concerns into parks and trails planning.
• Policy PR-1.8: Promote a healthy and active lifestyle for all residents.

5. Other Public Facilities: Public facilities include City-owned buildings, such as City Hall, the Wellness Center, and the Library, also known as the Civic Center Campus. The General Plan acknowledges that an increase in population would likely require the expansion of public facilities to serve the City’s anticipated future growth. The City’s CIP is updated annually and would play a key role in the planning and construction of future facilities (City of La Quinta, 2022). Future development would be subject to DIF fees which would offset impacts to public facilities Additionally the Specific Plan would be consistent with the following policies from the City’s General Plan:
• Policy PF-1.1: The City shall expand or modify municipal services to meet the needs of the community.
• Policy PF-1.2: Periodically evaluate the demand for municipal services and facilities, and include construction and expansion of these facilities to assure timely completion. • Policy PF-1.3: The City shall identify all viable financing mechanisms for the funding of construction, maintenance and operation of municipal facilities. • Policy PF-1.4: The design and construction of municipal facilities shall comply with all the processes and development standards that apply to privately constructed facilities. • Policy PF-1.5: The City shall coordinate with the County of Riverside to assure that library facilities and services are expanded as demand warrants. • Policy PF-1.6: The City shall coordinate with the Desert Sands and Coachella Valley Unified School Districts and encourage the Districts to plan for and construct new schools to meet demand.
• Policy PF-1.7: The City shall continue to explore the potential for the joint purchase or use of recreational facilities with the Desert Sands and Coachella Valley Unified School Districts, as well as the Coachella Valley Recreation and Park District.

The City currently operates 12 City parks, the Civic Center Campus, and three nature preserve areas. La Quinta Park is the closest park to the Project area outlined in this Specific Plan. Most City parks have children's playground facilities, and the nature preserves offer hiking and bicycling trails for public recreation. The CV Link is currently under construction which would provide a multi-modal trail for La Quinta and CV residents. In addition, many existing subdivisions include public pocket parks. Two regional parks – La Quinta Community Park (6.5 acres) and Lake Cahuilla Regional Park (845 acres) – are managed by the Desert Recreation District and Riverside County Parks Department, respectively. Lake Cahuilla Regional Park charges user fees for day visitors, fishing, and camping. The City collaborates with the Desert Sands Unified School District to share recreational facilities on school grounds, such as the Sports Complex at La Quinta Middle School and soccer fields at Colonel Mitchell Paige Middle School. The City is also home to one public and 22 privately owned and operated golf courses, with seven courses available for public use.

In total, La Quinta has approximately 5,259 acres designated as recreational open space (City of La Quinta, 2022).
a) Increase the use of existing neighborhood and regional parks or other recreational facilities such that substantial physical deterioration of the facility would occur or be accelerated? Less Than Significant Impact: The objective of the proposed Specific Plan is to offer a clear direction for the systematic development and redevelopment of local infrastructure, businesses, and housing. This may lead to a population increase, which may increase the use of existing neighborhood and regional parks and other recreational facilities. However, by adhering to the City’s General Plan, which recognizes that a population increase would necessitate the expansion of public facilities to accommodate growth, no substantial physical deterioration of such facilities would occur (City of La Quinta, 2022). The Parks and Recreation Element of the General Plan identifies current and projected demand for parks as the City grows. Adherence to the City’s General Plan would ensure that existing park and recreational facilities are expanded in parallel with population increases. Therefore, impacts on neighborhood and recreational facilities are anticipated to be less than significant.

City of La Quinta Highway 111 Corridor Specific Plan 3-95 b) Include or require the construction or expansion of recreational facilities, which might have an adverse physical effect on the environment?
Less Than Significant Impact: Population growth resulting directly or indirectly from the implementation of development scenarios in the Specific Plan may necessitate the construction or expansion of recreational facilities. The Quimby Act, also known as the Quimby Act of 1975 (California Government Code Sections 66477-66484), mandates that local governments require developers to either dedicate land or pay fees for park and recreational purposes when subdividing land or securing a residential development permit. The Act’s aim is to guarantee sufficient park and recreational facilities and accompany new residential developments, thereby balancing urban expansion with the demand for public open spaces. The Quimby Act empowers local governments to manage the impact of new residential projects on community parks and recreational amenities.

The Quimby Act sets a minimum threshold of 3.0 acres of parklands per 1,000 residents; however, the City has a policy of providing a minimum of 5.0 acres of open space per 1,000 residents. The General Plan acknowledges that expansion of recreational facilities would be needed as the City grows and would be regularly updating the City’s Community Service Master Plan to consider a growing demand for services well in advance of need. By adhering to the Land Use, Natural Resources and Parks and Recreational Elements of the City’s General Plan, as well as the Community Service Master Plan, impacts to recreational facilities are expected to be less than significant.

Roadways
Highway 111
The Highway 111 Corridor is a six-lane roadway that accommodates upwards of 28,700 vehicles daily (Replica: Hwy 111 WB W/O Washington St, 2023). Within the study area, Highway 111 has a six-lane divided cross-section with 50-mph posted speed limits. There are eight signalized intersections, located at Highway 111 and Washington Street, Simon Drive, La Quinta Center Drive, Adams Street, La Quinta Drive, Dune Palms Road, Costco Drive, and Jefferson Street. Dedicated left turn lanes are provided at all signalized intersections, with nearly all providing dedicated right turn lanes as well.

Highway 111 serves as a primary east-west connection through the CV between the City of La Quinta and communities to the northwest, including Palm Springs, Cathedral City, Rancho Mirage, Palm Desert, and Indian Wells, and communities to the southeast, including Indio, Coachella, and communities surrounding the Salton Sea and the Imperial Valley.

Washington Street
Within the study area, Washington Street is a divided six-lane major arterial with a landscaped median, with three left turn lanes and right turn pockets in both directions respectively at the intersection with Highway 111. This portion of Washington Street has a 50-mph posted speed limit and accommodates upwards of 17,900 vehicles daily (Replica: Washington St NB S/O Hwy 111, 2023). Washington Street does not accommodate on-street parking, as the surrounding land use is inward-facing residential and surface lotfacing retail. Signage instructs bicyclists to share the sidewalk on the east side of Washington Street with pedestrians.

Adams Street
Within the study area, Adams Street is a divided four-lane secondary arterial with a landscaped median between Highway 111 and Avenue 48, with two left turn lanes and right turn pockets in both directions respectively at the intersection with Highway 111. This portion of Adams Street has a 45-mph posted speed limit and accommodates upwards of 3,540 vehicles daily (Replica: Adams St NB N/O Hwy 111, 2023).

Dune Palms Road
Within the study area north of Highway 111, Dune Palms Road is an undivided four-lane secondary arterial with two left turn lanes and a right turn pocket at the intersection with Highway 111. South of Highway 111, Dune Palms Road is a divided four-lane arterial with two left turn lanes and a right turn pocket at the intersection with Highway 111. This portion of Dune Palms Road has a 45-mph posted speed limit and accommodates upwards of 2,890 vehicles daily (Replica: Dune Palms Rd NB N/O Hwy 111, 2023). Dune Palms Road does not accommodate on-street parking between Highway 111 and Avenue 48 as there are Class II bike lanes on either side. Partial Class II bike lanes and adjacent land use preclude on-street parking north of Highway 111.

Jefferson Street
Within the study area, Jefferson Street is a divided six-lane major arterial with a landscaped median, with three left turn lanes and right turn pockets in both directions respectively at the intersection with Highway 111. This portion of Jefferson Street has a 55-mph posted speed limit and accommodates upwards of 18,300 vehicles daily (Replica: Jefferson St SB N/O Hwy 111, 2023). Jefferson Street does not accommodate on-street parking due to the presence of Class II bike lanes.

Bicycle & Pedestrian Facilities
With the suburban nature of the City of La Quinta, multimodal infrastructure is available, including sidewalk and bicycle lanes along and adjoining Highway 111, however, it is often disconnected and distances between destinations are spread out due to the auto-oriented land use patterns along the corridor. Within the study area, pedestrian infrastructure is located along both sides of Highway 111, apart from segments with sidewalk gaps along undeveloped parcels, including east of La Quinta Drive (north side) and east of Dune Palms Road (north side). Sidewalks are most often 8 feet wide, exhibit serpentine alignment, and are separated from motor vehicle traffic by landscape buffers. Crosswalks are provided at signalized intersections of Highway 111/Washington Street (east side only), Highway 111/Simon Drive, Highway 111/La Quinta Center Drive, Highway 111/Adams Street, Highway 111/La Quinta Drive, Highway 111/Dune Palms Road, Highway 111/Costco Drive (east side crossing only), and Highway 111/Jefferson Street.

Existing bicycle facilities are sporadic and disconnected, with most portions of Highway 111 containing some form of bicycle facilities in at least one direction, but few, if any, connected to form a complete segment. Class II bicycle lanes are provided along portions of Highway 111 west and east of Washington Street (eastbound only), east of Simon Drive (eastbound only), east of La Quinta Center Drive (eastbound only), west of Adams Street (westbound only), between Adams Street and Dune Palms Road (both directions), and between Dune Palms Road and Jefferson Street (westbound only). Due to the number of vehicle lanes, high speeds, and bike infrastructure lacking physical separation between active modes and motor vehicles, the segment level of traffic stress on nearly all study area roadways is LTS 4 or LTS 3.

Segment LTS 1 is found on Simon Drive and La Quinta Center Drive due to fewer lanes and slower speeds.

Construction is ongoing for the planned CV Link project, an alternative transportation project connecting eight cities and two tribes in the CV, providing a regional multi-use path for bicycles and pedestrians that parallels the Highway 111 Corridor to the north throughout the Specific Plan area. The CV Link would provide an alternative to automobile travel for residents and visitors, reducing vehicle trips and vehicle miles traveled (VMT) and providing alternative mobility options for people of all ages and abilities. 389 Return to Agenda Link
Environmental Analysis
City of La Quinta Highway 111 Corridor Specific Plan 3-98 Public Transit
Existing regional transit routes in the study area include Route 1EV, Route 7, Route 700, and Route 701, all operated by SunLine Transit Agency. Route 1EV runs on Highway 111, connecting Town Center Way in Palm Desert (and connecting transit routes, like Route 1WV) with the City of Coachella. Route 7 provides transit service between the communities of Bermuda Dunes and La Quinta, connecting with the Highway 111 Corridor along Adams Street. Routes 700 and 701 are school “tripper buses” providing supplemental transit service to and from La Quinta High School on school days.

Airports
The Bermuda Dunes Airport is a public use airport located along Avenue 42 adjacent to the Jefferson Street/I-10 interchange approximately 2.7 miles north of the study area. Additionally, the Jacqueline Cochran Regional Airport is approximately 8 miles southeast of the study area in Thermal, California. a) Conflict with a program plan, ordinance or policy addressing the circulation system, including transit, roadway, bicycle and pedestrian facilities? No Impact: The Highway 111 Corridor Specific Plan includes urban design concepts that outline the proposed streetscape enhancements envisioned for the Highway 111 Corridor area. The Specific Plan would potentially increase traffic in the area along Highway 111. The CV Link's proximity to Highway 111 brings several advantages. First and foremost, it allows for enhanced accessibility, with multiple access points and entryways along the route, making it convenient for users to connect to various neighborhoods, businesses, parks, and other points of interest throughout the region. Additionally, being closely aligned with the highway can increase visibility and awareness, promoting the usage of the pathway among the public.

The Project proposes several complete street improvements in the study area to create a multimodal corridor that is safe and comfortable for all users. Transportation improvements include reduced vehicular travel lane widths, signs, and pavement markings, enhanced bicycle and pedestrian facilities like Class II bike lanes, green conflict striping, widened sidewalks, curb extensions (bulb-outs), high visibility crossing treatments, and reduced vehicular conflict zones. Additionally, the Specific Plan would be consistent with the City’s General Plan Circulation Goal, CIR-1, as outlined below:
• CIR-1: A transportation and circulation network that efficiently, safely and economically moves people, vehicles, and goods using facilities that meet the current demands and projected needs of the City.

Mitigation Measures: No mitigation measures required.
b) Conflict or be inconsistent with CEQA Guidelines section 15064.3, subdivision (b)? No Impact: The Highway 111 Corridor Specific Plan is not anticipated to conflict with CEQA Guidelines Section 15064.3 criteria for analyzing transportation impacts effective July 1, 2020 concerning VMT.

The VMT screening described below meets the requirements stipulated by CEQA Guidelines Section 15064.3 (b) and incorporates relevant advice contained in the Technical Advisory on Evaluating Transportation Impacts in CEQA published by the Governor’s Office of Planning & Research (OPR) in December 2018. Section 15064.3 of the State CEQA Guidelines describes the requirements for assessing transportation impacts based on VMT that applied statewide beginning July 1, 2020. As described in Section 15064.3:
390 Return to Agenda Link
Environmental Analysis
City of La Quinta Highway 111 Corridor Specific Plan 3-99 • “Vehicle miles traveled” refers to the amount and distance of automobile travel “attributable to a project.” Other relevant considerations may include the effects of the project on transit or nonmotorized travel. As described separately in the Technical Advisory on Evaluating Transportation Impacts in CEQA (OPR, December 2018), VMT re-routed from other origins or destinations as the result of a project would not be attributable to a project except to the extent that the re-routing results in a net increase in VMT. For example, OPR guidelines note that retail projects typically re-route travel from other retail destinations, and therefore a retail project may lead to increases or decreases in VMT, depending on previously existing travel patterns. Similarly, a large share of retail trips are “pass-by trips” that would not be considered attributable to a retail project.
• Lead agencies have discretion to choose the most appropriate methodology to evaluate a project’s vehicle miles traveled, including whether to express the change in absolute terms, per capita, per household, or any other measure.
• If existing models or methods are not available to estimate the vehicle miles traveled for the particular project being considered, a lead agency may evaluate the project’s vehicle miles traveled qualitatively.
• A lead agency may use models to estimate a project’s vehicle miles traveled and may revise those estimates to reflect professional judgment based on substantial evidence.

VMT Screening
The City’s Vehicle Miles Traveled Analysis Policy indicates that 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 Highway 111 Corridor Specific Plan covers multiple Traffic Analysis Zones (TAZs) of the Riverside County Transportation Model (RIVTAM/RIVCOM), including TAZ 913, 920, 926, 929, 930, and 937. Based on the model, the citywide VMT per Capita is 14.98 while the VMT for the Specific Plan area TAZs are as follows:
• TAZ 913: 12.92
• TAZ 920: 12.50
• TAZ 926: 12.74
• TAZ 929: 0.00
• TAZ 930: 11.45
• TAZ 937: 0.00
The VMT for each TAZ is lower than the City threshold for the base year (2018). Based on these findings, the Specific Plan does not require a VMT analysis as there is no impact.

Mitigation Measures: No mitigation measures required.

Environmental Analysis
City of La Quinta Highway 111 Corridor Specific Plan 3-100 c) Substantially increase hazards due to a geometric design feature (e.g., sharp curves or dangerous intersections) or incompatible uses (e.g., farm equipment)? No Impact: The Highway 111 Corridor Specific Plan is not anticipated to substantially increase hazards due to a geometric design feature (e.g., sharp curves or dangerous intersections) or incompatible uses (e.g., farm equipment).

The Highway 111 Corridor Specific Plan recommends the implementation of protected intersections, curb extensions, lane width reductions, turn lane reductions, Class II bike lanes with green conflict markings, high-visibility crosswalks, and Class I shared-use paths along the Highway 111 Corridor. Transportation improvements along other key corridors in the study area include roundabouts, curb extensions, reduced lane widths, Class II bike lanes with green conflict markings, and high-visibility crosswalks. With these recommended infrastructure improvements, the Specific Plan aims to reduce hazards by reducing pedestrian crossing distances, providing high visibility crossing treatments, and reducing vehicular conflict zones.

The General Plan includes policies that would ensure efficient circulation and adequate access are provided in the City. Future development under the Highway 111 Corridor Specific Plan, as part of the City’s project approval process, would be required to comply with existing regulations, including General Plan policies and zoning regulations that have been prepared to minimize impacts related to design features.

Adherence to state and City requirements, combined with compliance with the City’s General Plan and zoning regulations, would ensure that the adoption of the proposed Highway 111 Corridor Specific Plan would result in no impact with respect to an increase in hazards due to a geometric design feature or incompatible uses.

Mitigation Measures: No mitigation measures required.
d) Result in inadequate emergency access?
No Impact: The Highway 111 Corridor Specific Plan is not anticipated to result in inadequate emergency access. The Highway 111 Corridor Specific Plan proposes mixed-use development along the corridor, enhancing pedestrian and bicycle access, implementing parking solutions, and increasing the density of residential and commercial spaces. This aims to foster a more connected and community-centered downtown area. Roadway improvements proposed under the Specific Plan would enhance the connectivity and mobility of the downtown area and would not impede emergency vehicle access. As previously stated, transportation improvements along the Highway 111 Corridor focus on enhancing safety for pedestrians and vehicles through improved visibility at crosswalks and minimizing areas of vehicular conflict.

Furthermore, the City’s General Plan includes policies that would ensure adequate emergency access.

Future development within the Highway 111 Corridor Specific Plan, as part of the City's project approval process, must adhere to current regulations. These include General Plan policies and zoning regulations specifically designed to mitigate impacts concerning emergency access. The City, throughout the multi-year buildout period of the Highway 111 Corridor Specific Plan, would ensure relevant coordination with local emergency response providers. Adherence to state and City requirements, combined with compliance with the City’s General Plan and zoning regulations, would ensure that the adoption of the proposed Specific Plan would result in no impact with respect to inadequate emergency access.

Mitigation Measures: No mitigation measures required.

✓
The La Quinta area is home to the Desert Cahuilla Indians, who were the first ancestors of the La Quinta area, settling into the Martinez Canyon in the early 1800s (SCTCA, 2024).

The CEQA Guidelines define a tribal cultural resource as: (1) a site, feature, place, cultural landscape, sacred place, or object with cultural value to a California Native American Tribe that is listed or eligible for listing on the California Register of Historical Resources, or on a local register of historical resources as defined in Public Resources Code Section 5020.1(k); or (2) a resource determined by the Lead Agency, in its discretion and supported by substantial evidence, to be significant according to the historical register criteria in Public Resources Code Section 5024.1(c), and considering the significance of the resource to a California Native American Tribe.

AB 52 established a formal consultation process for California tribes within the CEQA process. AB 52 must be completed before a CEQA document can be certified. AB 52 specifies that any project may affect or cause a substantial adverse change in the significance of a tribal cultural resource that would require a lead agency to “begin consultation with a California Native American Tribe that is traditional and culturally affiliated with the geographic area of the proposed Project.” Section 21074 of AB 52 also defines a new category of resources under CEQA called “tribal cultural resources.” Tribal cultural resources are defined as “sites, features, places, cultural landscapes, sacred places, and objects with cultural value to a California Native American Tribe” and is either listed on or eligible for the California Register of Historic Resources (CRHR) or a local historic register, or if the lead agency chooses to treat the resource as a tribal cultural resource. California Native American Tribes to be included in the process are those that have requested notice of projects proposed within the jurisdiction of the Lead Agency.

Native American Consultation
On March 14, 2024, the City initiated the tribal consultation process for the purposes of AB 52, in conjunction with SB 18 consultation for the Specific Plan, for the proposed Project. Initial consultation letters were sent to all of the Native American tribal governments listed on the NAHC contact list, per the City’s AB 393 Return to Agenda Link
Environmental Analysis
City of La Quinta Highway 111 Corridor Specific Plan 3-102 52 protocol (Appendix C: Cultural Resources). The letters provided a summary of the Project and requested information regarding comments or concerns the tribal governments might have regarding the proposed Project. Letters were sent to the following tribal governments:
• Agua Caliente Band of Cahuilla Indians
• Augustine Band of Cahuilla Indians
• Cabazon Band of Mission Indians
• Cahuilla Band of Indians
• Campo Band of Diegueno Mission
Indians
• Ewiiaapaayp Band of Kumeyaay Indians
• La Posta Band of Diegueno Mission

• Ramona Band of Cahuilla
• Santa Rosa Band of Cahuilla Indians
• Soboba Band of Luiseno Indians
• Torres-Martinez Desert Cahuilla Indians
• Twenty-Nine Palms Band of Mission

The City received responses from two tribes: the Morongo Band of Mission Indians and the Agua Caliente Band of Cahuilla Indians (Appendix C: Cultural Resources). The Morongo Band stated that the project site is not within their ancestral territory or traditional use area. The Agua Caliente Band indicated that, although the project area is outside their reservation boundaries, it lies within their Traditional Use Area, and a records search identified nearby surveys that confirmed the presence of cultural resources.

For a summary of the investigation and mitigation measures related to cultural and tribal resources, see Section 3.5 Cultural Resources and Appendix C: Cultural Resources. a,b) Cause a substantial adverse change in the significance of a tribal cultural resource listed or eligible for listing in the California Register of Historic Resources, or in a local register of historic resources as defined in Public Resources Code section 5020.1(k)?

In applying the criteria set forth in subdivision (c) of the Public Resources Code section 5024.1, the lead agency shall consider the significance of the resource to a California Native American Tribe?
Less than Significant with Mitigation Incorporated: As discussed in Section 3.5, Cultural Resources, the analysis relies on a search of the SLF conducted by the NAHC on March 8, 2024. The search included a review of the CRHR as well as local registers yielding no specific site information, indicating a negative result. However, it is essential to understand that the absence of such information in the SLF search does not necessarily imply the absence of cultural resources within the Project area. Due to the negative result, the tribes (referenced above) were contacted to satisfy the AB 52 consultation requirement under CEQA.

This analysis is also based on a review of cultural records accessed through the CHRIS EIC at the University of California, Riverside. The examination of records occurred on January 22, 2024 involving a comprehensive review of maps, documents, and reports relevant to the Project area. The findings revealed that there have been 92 studies on cultural resources conducted within the approximately 410 acres of the proposed Project area, with 56 documented cultural resource properties identified within its boundaries. 394 Return to Agenda Link
Environmental Analysis
City of La Quinta Highway 111 Corridor Specific Plan 3-103 Refer to Appendix C: Cultural Resources for the SLF search results and the Non-Confidential Cultural Records Search report.

Potential future development may be required to prepare cultural resources reports to assess site-specific impacts. As mentioned previously, a prior study identified two prehistoric resources (P-33-008692/CA-RIV006190, P-33-002936/CA-RIV-002936) in the Project area near Dune Palms Road and Highway 111 (Hallock et al., 2023). As such, if tribal cultural resources are disturbed or discovered during future development, it could result in a significant impact. Therefore, implementing Mitigation Measures CR-1 through CR-9 during subsequent development phases would mandate further documentation of any tribal cultural resources within the Project area, thereby minimizing impacts to a level deemed less than significant.

Mitigation Measures
• CR-1: Workers Environmental Awareness Program
A Qualified Archaeologist who meets or exceeds the Secretary of Interior’s Professional Qualification Standards for archaeology (NPS, 1983) shall conduct Workers Environmental Awareness Program (WEAP) training on archaeological sensitivity for all construction personnel prior to the commencement of any ground-disturbing activities. Archaeological sensitivity training shall include a description of the types of cultural material that may be encountered, cultural sensitivity issues, the regulatory environment, and the proper protocol for treatment of the materials in the event of a find. The WEAP training document shall include materials that convey the information noted above, which shall be maintained in an area accessible to all construction personnel so that it may be reviewed regularly by construction staff. • CR-2: Pre-Excavation Agreement
Prior to the issuance of Grading Permits, the Applicant/Owner shall enter into a pre-excavation agreement, otherwise known as a Tribal Cultural Resources Treatment and Tribal Monitoring Agreement with consulting Tribal Monitor associated within the area. A copy of the agreement shall be included in building and development plans and permit applications with the City. The purpose of this agreement shall be to formalize protocols and procedures between the Applicant/Owner and the consulting Tribal Monitor associated with the area for the protection and treatment of, including but not limited to, Native American human remains, funerary objects, cultural and religious landscapes, ceremonial items, and traditional gathering areas and tribal cultural resources located and/or discovered through a monitoring program in conjunction with the construction of the proposed project, including additional archaeological surveys and/or studies, excavations, geotechnical investigations, grading, and all other ground disturbing activities. At the discretion of the consulting Tribal Monitor, artifacts may be made available for 3D scanning/printing, with scanned/printed materials to be curated at a local repository meeting the federal standards of 36CFR79. • CR-3: Retention of Qualified Archaeologist and Tribal Monitor Prior to the issuance of a Grading Permits, the Applicant/Owner or Grading Contractor shall provide executed contracts or agreements with a Qualified Archaeologist and consulting Tribal Monitor, at the Applicant/Owner or Grading Contractor’s expense, to implement the monitoring program, as described in the pre-excavation agreement.

The Qualified Archaeologist and consulting Tribal Monitor shall be present on-site full-time during grubbing, grading, and/or other ground altering activities, including the placement of imported fill materials or fill used from other areas of the Project site, to identify any evidence of potential archaeological or tribal cultural resources. All fill materials shall be absent of any and all tribal cultural resources.
• CR-5: Controlled Grade Procedure
The Qualified Archaeologist and consulting Native American Monitor shall attend all applicable preconstruction meetings with the General Contractor and/or associated subcontractors to present the archaeological monitoring program. The Qualified Archaeologist and consulting Tribal Monitor shall be present on-site full-time during grubbing, grading, and/or other ground altering activities, including the placement of imported fill materials or fill used from other areas of the Project site, to identify any evidence of potential archaeological or tribal cultural resources. All fill materials shall be absent of any and all tribal cultural resources.
• CR-6: Discovery of Tribal Cultural Resources
The Qualified Archaeologist and consulting Tribal Monitor can stop ground-disturbing activities if undiscovered tribal cultural resources or artifacts are found. All work must cease in the vicinity of any archaeological discovery until the Qualified Archaeologist and Tribal Monitor can assess the context of the find, including its significance, potential eligibility for the California Register of Historical Resources (CRHR), and whether the project would have a direct impact on the resource.

If buried cultural deposits are encountered, the Archaeologist and Tribal Monitor may request that construction halt nearby and must notify a Qualified Archaeologist within 24 hours for investigation.

Work will be redirected away from these areas for assessment. Minor finds will be documented and secured for later repatriation; if items cannot be securely stored on-site, they may be stored off-site.

Minor finds include archaeological materials that are isolated, lack context, and are unlikely to indicate a larger or significant site. If the discovered resources are deemed potentially significant, the involved Tribes will be notified for consultation on their respectful treatment. Avoidance of significant resources is preferred, but if not feasible, a data recovery plan may be required. The consulting Tribes will be consulted on this plan as well.

For resources under a data recovery plan, a proper sample will be collected using professional methods, reflecting tribal values. The Tribal Monitor must be present during any resource collection or cataloging. If the Qualified Archaeologist does not collect the resources, the Tribal Monitor may do so. Ground-disturbing work will not resume until the resources are documented and/or protected. • CR-7: Treatment of Tribal Cultural Resources
The landowner shall relinquish ownership of all cultural resources unearthed during all ground disturbing activities, and from any previous archaeological studies or excavations on the Project site to the affiliated consulting Tribe, as determined through the appropriate process, for respectful and dignified treatment and disposition, including reburial at a protected location on-site, in accordance with the Tribe’s cultural and spiritual traditions.

As the City continues to grow, the provision of essential public and quasi-public services becomes increasingly critical. This is especially true for areas like the Highway 111 Corridor, where utilities play a pivotal role in supporting future development. Adequate utilities – such as water, sewer, electricity, natural gas, and telecommunications – are fundamental for implementing the Specific Plan. Without these services, the planned development and expansion could be significantly hindered or even unachievable. Ensuring robust and reliable utility infrastructure is, therefore, essential for accommodating growth and achieving the City's long-term vision for development.

The Specific Plan would create a mix of land uses guided by site-specific development standards (i.e., Highway 111 Development Code) to ensure alignment with the City's General Plan. It would also encourage water conservation features, such as low-flow plumbing fixtures, drought-tolerant native landscaping, and efficient irrigation systems. The City’s General Plan recognizes the need for sufficient water, sewer, and other utilities to support planned growth and anticipated population increases in the coming years. The Water, Sewer and other Utilities Element as well as the Natural Resources: Water Resources Element of the General Plan establishes goals, policies, and programs to ensure these services are provided as the City grows (City of La Quinta, 2022). Relevant General Plan policies are outlined in detail below in response to question b).
398 Return to Agenda Link
Environmental Analysis
City of La Quinta Highway 111 Corridor Specific Plan 3-107 Domestic Water
The City of La Quinta relies primarily on groundwater from the CV Groundwater Basin for its domestic water supply. This groundwater is extracted through a network of wells managed by the CVWD, which also oversees the City's irrigation and water distribution services.

In addition to groundwater, CVWD supplements the City's water needs with imported water, delivered via regional canals. This imported water is stored or recharged into the aquifer through basins located in the west end of the Valley, such as the Whitewater River northwest of Palm Springs, as well as through facilities in Martinez Canyon and a dike in the southeastern section of the City.

CVWD operates and maintains an extensive water distribution system, primarily located beneath existing streets in the public right-of-way. CVWD also manages water storage tanks throughout the area with capacities ranging from 250,000 to 10 million gallons (City of La Quinta, 2022).

Under the California Water Code, CVWD is responsible for assessing both current and future water supplies to ensure that adequate resources are available for the City's land uses. This includes the preparation of an Urban Water Management Plan (UWMP) to address and plan for the City's ongoing and future water needs.

Sanitary Sewer
CVWD also manages sanitary sewer collection and treatment for the City, with most areas served by sewer systems, though some parts of the City still use septic systems. The City is served by two wastewater treatment plants. Wastewater from the northern part of the City, north of Miles Avenue, is directed to Water Reclamation Plant 7 on Madison Street and Avenue 38, which has a capacity of 5 million gallons per day (mgd). Wastewater from areas south of Miles Avenue is treated at the Mid-Valley Water Reclamation Plant, located southeast of the City, with a capacity of 9.5 mgd.

Water Reclamation Plant 7 currently produces 2.5 mgd of tertiary treated water for irrigation, with the potential to expand to 7.5 mgd. The Mid-Valley plant does not yet provide tertiary treated water, but there are plans to extend this system to other areas (City of La Quinta, 2022).

Electricity
Power in the City is supplied by the IID, a public utility serving various parts of Southern California. IID delivers power through its own generation and contractual agreements, with electricity transmitted at 92 or 161 kilovolts to its substations and then reduced to 12 kilovolts for distribution (City of La Quinta, 2022).

Natural Gas
Natural gas is the main energy source in the City of La Quinta, supplied by Southern California Gas Company (SoCalGas), the largest natural gas utility in the U.S. with extensive coverage across southern California. Major gas supply lines run along Washington Street and Highway 111. However, natural gas service is less extensive in the southern part of the City, especially south of Airport Boulevard and east of Monroe Street (City of La Quinta, 2022; City of La Quinta, 2024c).

Solid Waste Management
Burrtec Waste and Recycling Services, LLC (Burrtec) manages solid waste disposal in La Quinta. Burrtec collects waste and transport it to the Edom Hill Transfer Station in Cathedral City, where it is then sent to regional landfills with sufficient long-term capacity: Lamb Canyon, Badlands, or El Sobrante. Burrtec also oversees recycling for residential and commercial sectors, covering paper, plastic, glass, aluminum, and 399 Return to Agenda Link
Environmental Analysis
City of La Quinta Highway 111 Corridor Specific Plan 3-108 green waste. The City meets its requirement to recycle at least 50% of its waste. Additionally, Burrtec handles special programs for household hazardous waste, construction and demolition materials, medical sharps, and commercial recycling (City of La Quinta, 2022; City of La Quinta, 2024c).

Telecommunications
In the City, Verizon serves as the primary landline telephone provider, while Time Warner is the main cable TV provider. The City has seen a range of communication options evolve due to advancements in technology and changes in regulations. Residents and businesses now have access to various services, including cellular, internet-based communication, fiber optic networks, and cable-based solutions. Several telecommunications companies such as Spectrum, which offers cable TV, internet, and phone services, AT&T, which provides internet, phone, and TV services, and Frontier Communications, which delivers internet and phone services with varying availability, cater to these needs (City of La Quinta, 2022). As the City continues to grow, it is anticipated that new technologies would further enhance communication and data transfer capabilities for both its residents and businesses. a) Require or result in the relocation or construction of new or expanded water, wastewater treatment or storm water drainage, electrical power, natural gas, or telecommunications facilities, the construction or relocation of which could cause significant environmental effects?
Less Than Significant Impact: Under the Specific Plan, if the proposed buildout is economically feasible, it is expected to lead to a substantial increase in the construction of new buildings and utilities as well as the expansion of existing ones. This growth would entail the addition of significant square footage dedicated to various purposes, including residential, retail, office spaces, and hotels. Consequently, there would be a heightened demand for essential utilities and infrastructure to support these developments effectively.

To accommodate the increased requirements of such development, various utility facilities would need to be constructed or expanded. These utilities may encompass water supply and distribution systems, wastewater treatment plants, stormwater drainage systems, electrical power infrastructure, natural gas distribution networks, and telecommunications facilities. Each of these systems plays a crucial role in providing the necessary resources for the functioning of residential and commercial properties, ensuring that businesses can thrive and residents have access to essential services.

To address the potential environmental impacts associated with this buildout, the Specific Plan emphasizes the importance of adhering to the Water, Sewer, and Other Utilities Element within the City’s General Plan.

This element outlines comprehensive guidelines and regulations regarding the development and management of utility facilities based on current and future projected population growth within the City.

Additionally, the Natural Resources: Water Resources Element of the City’s General Plan is another crucial aspect considered in this context, which focuses on water resource management and conservation to meet the needs of current and future development within the City. By adhering to these General Plan guidelines and the goals outlined by this Specific Plan, developers and authorities can ensure that future construction and expansion of utility facilities are conducted in sustainable manner. Additionally, future development in the Specific Plan area will utilize this impact analysis for environmental assessments, offering a programmatic overview that will likely be tiered from this document to evaluate impacts on new or expanded utilities within the area. As such, impacts on utility systems as a result of this Specific Plan implementation are anticipated to be less than significant.

Mitigation Measures: No mitigation measures required.

Environmental Analysis
City of La Quinta Highway 111 Corridor Specific Plan 3-109 b) Have sufficient water supplies available to serve the project and reasonably foreseeable future development during normal, dry and multiple dry years? Less Than Significant Impact with Mitigation Incorporated: As the new developments under the Specific Plan commence, they would require a reliable and adequate water supply to meet the needs of their occupants and operations. This includes not only the water required for residential purposes but also for commercial activities, hotel services, landscaping, and other essential functions within these structures.

To accommodate the heightened demand, proper planning and management of water resources become crucial. This may involve assessing the existing water infrastructure and identifying potential upgrades or expansions to ensure sufficient supply to meet the new demand. It might also require exploring sustainable water management practices, such as rainwater harvesting, water recycling, or implementing water-efficient technologies and fixtures, to minimize excessive water consumption.

CVWD is responsible under the California Water Code for evaluating current and future water supplies to meet district needs. The UWMP is regularly updated to ensure it remains current. Due to ongoing growth and increased demand, CVWD has overdrafted from the Lower Thermal subarea since the 1980s. To address this, CVWD is expanding recharge facilities and emphasizing water conservation, crucial for managing overdraft as the city continues to grow. Additionally, all new residential and nonresidential buildings in California must follow the CalGreen Codes. These codes mandate a 20% reduction in indoor water use through efficient fixtures and require irrigation systems that prevent waste by monitoring soil and weather conditions. Please refer to California Department of General Services for the most recent CalGreen Codes (DGS, 2024). Over the next 25 years, the codes would become progressively stricter to further conserve water (City of La Quinta, 2022).

All new development projects would necessitate domestic water for indoor use and landscaping irrigation, which would put additional strain on the already limited water resources. To address this, the City has already taken steps to implement water conservation initiatives and would need to persistently and further expand these efforts to safeguard its water resources (City of La Quinta, 2022). By adhering to the goals and objectives outlined in the City’s General Plan as well as this Specific Plan, future development can reduce potential impacts on water resources to a less than significant level with the incorporation of proposed mitigation measure HWQ-2.

Relevant Policies from the General Plan:
• Policy WR-1.1: Support the Coachella Valley Water District in its efforts to supply adequate domestic water to residents and businesses.
• Policy WR-1.2: Support the Coachella Valley Water District in its efforts to recharge the aquifer. • Policy UTL-1.1: The City should coordinate with the Coachella Valley Water District to assure that sufficient water supplies are available to sustain current and future development. • Policy UTL-1.2: The City should encourage the conservation of water. − Program UTL-1.2a: Develop programs, both in conjunction with the Coachella Valley Water District and independently, to allow and encourage the retrofitting of existing water-intensive appliances and irrigation systems in existing development − Program UTL-1.2b: City and private sector development projects shall implement water efficient landscaping plans which meet or exceed current water efficiency standards. 401 Return to Agenda Link
Environmental Analysis
City of La Quinta Highway 111 Corridor Specific Plan 3-110 • Policy UTL-1.3: New development shall reduce its projected water consumption rates over “business-as-usual” consumption rates.
• Policy UTL-1.4: Review and amend Development Standards to require that all new development demonstrate a reduction of domestic water consumption equivalent to, or exceeding, the CalGreen Tier One standards in effect at the time of development.

Mitigation Measures: HWQ-2.
c) Result in a determination by the wastewater treatment provider which serves or may serve the project that it has adequate capacity to serve the project’s projected demand in addition to the provider’s existing commitments?
Less Than Significant Impact: Future development scenarios outlined in the Specific Plan would likely increase the need and demand for wastewater treatment. Future development would need to adhere to Building Code requirements that mandate the incorporation of water-efficient fixtures in new homes or businesses and in those undergoing major remodeling. These regulations also apply to water features, and fountains, as they can be a significant source of water loss, especially considering the evaporation that occurs in the City's desert environment.

The City also mandates that all development projects must manage and regulate rainwater runoff that flows through a developed site, typically achieved by constructing retention basins. These basins are often landscaped and designed to enable stormwater to soak into the ground, promoting natural percolation (City of La Quinta, 2022). Therefore, future development under the Specific Plan would be required to adhere to these requirements.

The Specific Plan offers conceptual guidance for future development. Developers can reference this Specific Plan and if needed, create a tiered CEQA document to further assess the need for expanding existing wastewater treatment facilities or adding individual septic systems to accommodate growth in the area. As such, impacts are expected to be less than significant.

Relevant Policies from the General Plan:
• Policy WR-1.3: Support the Coachella Valley Water District in its efforts to expand tertiary treated (i.e. reclaimed) water distribution.
• Policy WR-1.4: Protect stormwater from pollution and encourage its use to recharge the aquifer. • Policy WR-1.6: Encourage the use of permeable pavements in residential and commercial development projects.

Mitigation Measures: No mitigation measures required.
d, e) Generate solid waste in excess of State or local standards, or in excess of the capacity of local infrastructure, or otherwise impair the attainment of solid waste reduction goals? Comply with federal, state, and local management and reduction statutes and regulations related to solid waste?
Less than Significant Impact: As development continues to grow under the Specific Plan, there would be a corresponding rise in the volume of solid waste generated. Burrtec provides waste disposal services under a franchise agreement with the City, collecting solid waste and transporting it to the Edom Hill Transfer Station in Cathedral City. From there, waste is taken to one of three regional landfills – Lamb 402 Return to Agenda Link

City of La Quinta Highway 111 Corridor Specific Plan 3-111 Canyon, Badlands, or El Sobrante – which have sufficient capacity for long-term needs (City of La Quinta, 2022). Thus, impacts are expected to be less than significant.

All future developments would be required to comply with the diversion requirements, Municipal Code requirements and the City’s General Plan policies. These requirements would maximize waste stream diversions and help reduce solid waste disposal impacts related to compliance with federal, state, and local regulations related to the solid waste generated from future development in accordance with the Specific Plan.

The City is committed to recycling at least 50% of its solid waste, a target it currently meets. Burrtec manages specialized programs for household hazardous waste, construction materials, medical "sharps," and commercial recycling (City of La Quinta, 2022). Future site-specific development would be required to abide by relevant laws and regulations governing solid waste disposal treatment. As such, impacts associated with solid waste are expected to be less than significant.

Mitigation Measures: No mitigation measures required.

Utilities and Service Systems Mitigation Measures
• HWQ-2: Water Conservation Measures
Future development in the Highway 111 Corridor must integrate water-saving appliances and fixtures, such as low-flush toilets, low-flow showerheads, and faucets, in compliance with Section 17921.3 of the Health and Safety Code, Title 20 of the California Administrative Code Section 1601(b), and relevant sections of Title 24 of the California State Code. Additionally, the City would enforce its Water Efficient Landscape ordinance, requiring development projects within the Specific Plan area to adopt water-efficient landscaping plans that meet or exceed current criteria. These measures are aimed at conserving water resources while addressing the needs of residents and businesses.

The Project area is located in the City’s urban core and is not in proximity to a Fire Hazard Severity Zone (CAL FIRE, 2023). The nearest moderate Fire Hazard Severity Zone is approximately 5 miles southwest of the Project area.
a) Substantially impair an adopted emergency response plan or emergency evacuation plan? Less Than Significant Impact: The LHMP for the City underscores a commitment to construction regulations that prioritize safety. This involves adopting and rigorously enforcing existing building codes, with provisions for promptly amending them when local deficiencies are identified, all aimed at ensuring the community's safety. All new construction projects are required to adhere to the City's Building or Fire Codes to ensure all future development meets the prescribed minimum standards for fire safety. These standards are determined by factors such as the building type, design, intended occupancy, and usage. To further enhance fire safety measures, the City has entered into an agreement with the RCFD for comprehensive fire services. These services encompass not only firefighting capabilities but also extend to community outreach initiatives aimed at promoting fire safety awareness and prevention strategies (City of La Quinta, 2022). Future developments would be required to implement the LHMP and General Plan policies regarding emergency response and evacuation; therefore, impacts are anticipated to be less than significant.

Mitigation Measures: No mitigation measures required.

Environmental Analysis
City of La Quinta Highway 111 Corridor Specific Plan 3-113 b) Due to slope, prevailing winds, and other factors, exacerbate wildfire risks, and thereby expose project occupants to pollutant concentrations from a wildfire or the uncontrolled spread of a wildfire?
Less Than Significant Impact: The proposed area under the Specific Plan is not considered a Fire Hazard Severity Zone (CAL FIRE, 2023). While the City itself may not be situated within a wilderness expanse, the potential for wildland fires within its vicinity remains substantial due to the juxtaposition of wildland and urban zones. The extensive development in the City and surrounding environment has resulted in what is known as the Wildland-Urban Interface (WUI), a terrain that presents a heightened susceptibility to wildland fires. This vulnerability is exacerbated by the prevalence of extended drought periods and the prevalent aridity in these locales, rendering them particularly prone to wildfires (City of La Quinta, 2022).

Furthermore, the influence of Santa Ana winds provides an additional fire safety concern. These winds possess the capability to swiftly propagate wildfires across the community. The threat of wildland fire occurrences extends far beyond isolated areas; it blankets approximately 90% of Riverside County, reaching into the City. This includes open spaces, parklands, and agricultural regions. Therefore, the issue of wildland fire hazards is a complex concern with wide-reaching implications for the entire region. This underscores the need for comprehensive attention and strategic actions to effectively manage and mitigate the associated risks. (City of La Quinta, 2022).

Development under the Specific Plan would include the development of Medium-Hazard Occupancies as defined by the National Fire Protection Association (NFPA), however, by adhering to and enforcing established mandates, such as the California Building Code, California Fire Code, La Quinta Municipal Codes, CEQA Statutes and Guidelines, and other pertinent fire safety regulations, the mitigation of firerelated risks can be effectively managed (La Quinta, 2022). Therefore, less than significant impacts are anticipated.

Mitigation Measures: No mitigation measures required.
c) Require the installation or maintenance of associated infrastructure (such as roads, fuel breaks, emergency water sources, power lines or other utilities) that may exacerbate fire risk or that may result in temporary or ongoing impacts to the environment? Less Than Significant Impact: The Specific Plan serves as a policy-level document designed to guide future development along the Highway 111 Corridor. Consequently, any future projects within the Specific Plan area will likely reference and tier off of this CEQA document to further assess infrastructure constraints related to fire risks. Additional discussion of water sources and utilities can be found in Section 3.19 of this IS/MND. Future projects may necessitate additional infrastructure to adequately support new development.

Any future development would require further CEQA review to ensure that proposed improvements do not entail infrastructure that could worsen wildfire risks. The adoption and implementation of developments under the Specific Plan would not significantly exacerbate wildfire risks above existing conditions. As such, impacts are considered to be less than significant.

Mitigation Measures: No mitigation measures required.

City of La Quinta Highway 111 Corridor Specific Plan 3-114 d) Expose people or structures to significant risks, including downslope or downstream flooding or landslides as a result of runoff, post-fire slope instability, or drainage changes? Less than Significant Impact: As described previously, the Specific Plan does not include any sitespecific designs for development and is only intended to serve as a guidance document for the City in implementing future development along the Highway 111 Corridor. The Specific Plan area occupies a predominantly flat terrain and is generally not susceptible to downslope flooding or landslides due to its topographic features. As such, future development along the Project area is not anticipated to expose people or structures to significant risks, including downslope or downstream flooding or landslides, as a result of runoff, post-fire slope instability, or drainage changes. Portions of the Project area that are adjacent to the Whitewater River Wash are located within Special Flood Hazard Areas; however, these areas have between 0.2% and 1% annual chance of flooding with average depths of less than one foot or with drainage areas of less than one square mile. There are no FEMA-regulated floodways identified within the Project area (FEMA, 2024). Impacts are deemed less than significant.

Less Than Significant Impact with Mitigation Incorporated: As outlined in Section 3.4, Biological Resources, the proposed Specific Plan is expected to have no direct impact on biological resources. Future improvements under the Specific Plan would comply with relevant federal, state, and local regulations. The implementation of Mitigation Measure BIO-1 would ensure construction personnel receive environmental awareness training to mitigate potential impacts on special-status species and their habitats. Similarly, BIO2 would establish best practices to minimize impacts on natural habitats and wildlife. Furthermore, implementation of BIO-3 would guide the protection of special-status and migratory birds during construction, and BIO-4 would provide specific guidance on focused burrowing owl surveys. Mitigation Measures BIO-5 and BIO-6 offer strategies for reducing nonessential lighting to safeguard wildlife at the Project site, as well as guidance on securing approval from CDFW under Section 1602 of the Fish and Game Code for any impacts to a stream or riverbed. Lastly, BIO-7 would emphasize adherence to conservation measures specified in the CVMSHCP. Together, these measures would effectively reduce impacts to species and their habitats to less than significant levels.

Similarly, as detailed in Section 3.5, Cultural Resources, the proposed Specific Plan is not expected to impact significant periods of California history or cultural and historic resources. Future developments 407 Return to Agenda Link
Environmental Analysis
City of La Quinta Highway 111 Corridor Specific Plan 3-116 outlined in the Specific Plan would be subject to mitigation measures CR-1 through CR-9, ensuring that any unearthed resources are properly managed. With the implementation of these cultural mitigation measures, impacts to cultural and historic resources are anticipated to be reduced to less than significant levels.

Mitigation Measures: BIO-1 through BIO-7, and CR-1 through CR-9. b) Does the project have impacts that are individually limited, but cumulatively considerable? (“Cumulatively considerable” means that the incremental effects of a project are considerable when viewed in connection with the effects of past projects, the effects of other current projects, and the effects of probable future projects)? Less Than Significant Impact with Mitigation Incorporated: Cumulative impacts are defined as “two or more individual effects which, when considered together, are considerable or which compound or increase other environmental impacts” (CEQA Guidelines Section 15355). Cumulative impacts can result from individually minor, but collectively significant actions taking place over a period of time.

This Specific Plan aligns with the City’s General Plan policies and goals as well as City Codes. Evidence in this Finding of Consistency shows no new significant environmental effects beyond those identified in the City’s General Plan. The General Plan envisions the Highway 111 Corridor evolving into a prime mixed-use area, reflecting its goals for innovative development. This Specific Plan would guide the transformation of Highway 111 to improve quality of life for residents, employees, and visitors, envisioning it as a standout destination offering a variety of memorable experiences.

Future development guided by this Specific Plan may have cumulative impacts on air quality, natural resources, hazards, cultural/tribal resources, public services, and population and housing. While future development along the Highway 111 Corridor would lead to some environmental changes, potential impacts associated with these environmental disciplines are expected to be minor or mitigated to a less significant level through recommended measures in the Specific Plan. This approach would also ensure that any contribution to cumulative impacts remains minimal.

The impacts associated with the proposed Specific Plan would not add appreciably to any existing or foreseeable future significant cumulative environmental impact. Incremental impacts, if any, would be negligible. All potential direct and indirect impacts of the Project can be avoided or minimized to a level that is considered insignificant, as summarized in Appendix A: Mitigation Monitoring and Reporting Program (MMRP). Consequently, the proposed Project's cumulative impacts are not considered significant, as any applicable impacts it may contribute to would be mitigated to a less than significant level.

Mitigation Measures: BIO-1 through BIO-7, CR-1 through CR-9, AIR-1, GEO-1, HAZ-1, HAZ-2, HWQ-1, HWQ-2, and NOI-1.
c) Does the project have environmental effects which would cause substantial adverse effects on human beings, either directly or indirectly?
Less Than Significant Impact with Mitigation Incorporated: Future development contemplated by the proposed Specific Plan could potentially lead to environmental impacts related to air quality, geology and soils, hazardous materials, water quality, noise, and utilities. While the Specific Plan itself does not involve construction, it serves as a guide for future development. The IS/MND for the Specific Plan ensures compliance with regulations to mitigate these potential impacts. Mitigation Measures AIR-1, GEO-1, HAZ-1, HAZ-2, HWQ-1, HWQ-2, and NOI-1 would help lessen environmental impacts by minimizing pollutants and conserving natural resources, thereby reducing direct health risks and indirect effects on important ecosystems that support human well-being. With these measures in place, the Specific Plan is expected to avoid significant adverse effects on human health and the environment.

Mitigation Measures: AIR-1, GEO-1, HAZ-1, HAZ-2, HWQ-1, HWQ-2, and NOI-1. 409 Return to Agenda Link
Environmental Analysis
City of La Quinta Highway 111 Corridor Specific Plan 3-118 Mandatory Findings of Significance Mitigation Measures:
• BIO-1: Assessment of Biological Resources and Worker Environmental Awareness Training
Prior to Project construction activities for all projects covered in this IS/MND, a complete and recent inventory of rare, threatened, endangered, and other sensitive species located within the Project footprint and within offsite areas with the potential to be affected, including California Species of Special Concern and California Fully Protected Species (Fish and Game Code § 3511), will be completed. Species to be addressed should include all those which meet the CEQA definition (CEQA Guidelines § 15380). The inventory should address seasonal variations in use of the Project area and should not be limited to resident species. Focused species-specific surveys, completed by a qualified biologist and conducted at the appropriate time of year and time of day when the sensitive species are active or otherwise identifiable are required. Acceptable species-specific survey procedures should be developed in consultation with CDFW and the U.S. Fish and Wildlife Service, where necessary. Note that CDFW generally considers biological field assessments for wildlife to be valid for a one-year period, and assessments for rare plants may be considered valid for a period of up to three years. Some aspects of the proposed Project may warrant periodic updated surveys for certain sensitive taxa, particularly if the Project is proposed to occur over a protracted time frame, or in phases, or if surveys are completed during periods of drought.

An environmental training program should be developed and presented by a qualified biologist to all crew members prior to the beginning of all Project construction in natural areas planned for development. The training should describe special-status plant and wildlife species and sensitive habitats that could occur within the Project area, protection afforded to these species and habitats, and avoidance and minimization measures required to avoid and/or minimize impacts from the project.

All new construction personnel should receive this training before beginning work on this Project. A copy of the training and training materials should be provided to construction crews for review and approval at least 30 days prior to the start of construction. As needed, in-field training should be provided to new on-site construction personnel by the qualified biologist or a qualified individual who should be identified by the qualified biologist, or initial training should be recorded and replayed for new personnel.
• BIO-2: General Measures for Plants and Wildlife
When working in the natural habitat areas, the number of access routes, number and size of staging areas, and the total area of the activity should be limited to the minimum necessary to achieve the project goal. Routes and boundaries outside of normal access roads should be clearly delineated through fencing or flagging.

Food, trash, and other solid wastes should be disposed of in Common Raven proof/wildlife proof, covered refuse containers and regularly removed from the various structures and facilities on a daily basis to avoid offsite dispersal of waste and to avoid attracting wildlife onto the Project site.

Following covered activity work, all trash and debris should be removed from the work area.

Construction work should avoid direct destruction of burrows through chaining (dragging a heavy chain over an area to remove shrubs), disking, cultivation, and urban, industrial, or agricultural development.
410 Return to Agenda Link
Environmental Analysis
City of La Quinta Highway 111 Corridor Specific Plan 3-119 Project-related excavations greater than 6 inches deep should be secured to prevent wildlife entry and entrapment. Holes and trenches should be back-filled, securely covered, or fenced. Excavations that cannot be fully secured should incorporate appropriate wildlife ramp(s) at a slope of no more than a 3:1 ratio (horizontal: vertical, equivalent to a 33.3 percent or 18.4-degree slope), or other means to allow trapped animals to escape.

Personnel on site should be required to check under their vehicles for sensitive species prior to moving them and should exercise caution while driving on the Project site.

Before moving, burying, or capping, inspect for wildlife in any construction pipes, culverts, or similar structures that are stored on the site for one or more nights. Alternatively, cap structures before storing on the work site.
• BIO-3: Special Status and Migratory Birds
Construction should be conducted, if possible, during the fall and/or winter months and outside of the avian nesting season (generally February 1 – August 31) to avoid any direct and or indirect effects to protected nesting birds. Pre-construction surveys shall focus on both direct and indirect evidence of nesting, including nest locations and nesting behavior. The qualified avian biologist will make every effort to avoid potential nest predation as a result of survey and monitoring efforts. If active nests are found during the pre-construction nesting bird surveys, a qualified biologist shall establish an appropriate nest buffer to be marked on the ground. Nest buffers are species specific and shall be at least 100 feet for passerines and 300 feet for raptors. A smaller or larger buffer may be determined by the qualified biologist familiar with the nesting phenology of the nesting species and based on nest and buffer monitoring results. Construction activities may not occur inside the established buffers, which shall remain on-site until a qualified biologist determines the young have fledged or the nest is no longer active. Active nests and adequacy of the established buffer distance shall be monitored at least once a week or as needed by the qualified biologist until the qualified biologist has determined the young have fledged or the Project has been completed. The qualified biologist has the authority to stop work if nesting pairs exhibit signs of disturbance. • BIO-4: Burrowing Owl Habitat Assessment and Focused Pre-Construction Surveys No less than 60 days prior to the start of Project-related activities for all projects covered in the MND, a burrowing owl habitat assessment shall be conducted by a qualified biologist according to the specifications of the Staff Report on Burrowing Owl Mitigation (Department of Fish and Game, March 2012 or most recent version) for all projects covered under the MND.

If the habitat assessment demonstrates suitable burrowing owl habitat, then focused burrowing owl surveys shall be conducted by a qualified biologist in accordance with the Staff Report on Burrowing Owl Mitigation (2012 or most recent version) prior to vegetation removal or ground-disturbing activities. If burrowing owls are detected during the focused surveys, the qualified biologist and Project proponent shall begin coordination with CDFW and USFWS immediately, and shall prepare a Burrowing Owl Avoidance and Monitoring Plan that shall be submitted to CDFW for review and approval prior to commencing Project activities. The Burrowing Owl Plan shall describe proposed avoidance and monitoring actions, including measures necessary to avoid take of burrowing owl individuals, nests, and eggs. The Burrowing Owl Plan shall include the number and location of occupied burrow sites (occupied site means at least one burrowing owl or its sign has been observed within the last three years; may be indicated by owl sign including feathers, pellets, prey remains, eggshell fragments, or excrement at or near a burrow entrance or perch site), acres of burrowing owl habitat that will be impacted, details of site monitoring, and details on proposed 411 Return to Agenda Link

City of La Quinta Highway 111 Corridor Specific Plan 3-120 buffers and other avoidance measures. If impacts to occupied burrowing owl habitat or burrow(s) or burrowing owl individuals, nests, or eggs cannot be avoided, appropriate California Endangered Species Act (CESA) authorization (i.e., Incidental Take Permit under Fish and Game Code section 2081) should be obtained from CDFW prior to commencement of Project activities.

Preconstruction burrowing owl surveys shall be conducted no less than 14 days prior to the start of Project-related activities and within 24 hours prior to ground disturbance, in accordance with the Staff Report on Burrowing Owl Mitigation (2012 or most recent version). Preconstruction surveys should be repeated when there is a pause in construction of more than 30 days. Preconstruction surveys should be performed by a qualified biologist following the recommendations and guidelines provided in the Staff Report on Burrowing Owl Mitigation. If the preconstruction surveys confirm occupied burrowing owl habitat, Project activities shall be immediately halted. The qualified biologist shall coordinate with CDFW and prepare a Burrowing Owl Avoidance and Monitoring Plan that shall be submitted to CDFW and USFWS for review and approval prior to commencing Project activities. • BIO-5: Artificial Light Impacts
Throughout construction and the lifetime operation of all projects covered in the IS/MND the City and Project proponents shall eliminate all nonessential lighting throughout the Project area and avoid or limit the use of artificial light at night during the hours of dawn and dusk when many wildlife species are most active. The City and Project proponent shall ensure that all lighting for the Project is fully shielded, cast downward and directed away from surrounding open-space and agricultural areas, reduced in intensity to the greatest extent possible, and does not result in lighting trespass including glare into surrounding areas or upward into the night sky (see the International Dark-Sky Association standards at http://darksky.org/). The City and Project proponent shall ensure use of LED lighting, proper disposal of hazardous waste, and recycling of lighting that contains toxic compounds with a qualified recycler.
• BIO-6: CDFW Lake and Streambed Alteration (LSA) Program Prior to construction and issuance of any grading permit, the Project Sponsor shall obtain written correspondence from CDFW stating that notification under Section 1602 of the Fish and Game Code is not required for the Project, or the Project Sponsor should obtain a CDFW-executed Lake and Streambed Alteration Agreement, authorizing impacts to Fish and Game Code Section 1602 resources associated with the Project.
• BIO-7: Project Adherence to the CVMSHCP
All Conservation Measures that are applicable within Section 4.4 (Required Avoidance, Minimization, and Mitigation Measures) and Section 9 (Species Accounts and Conservation Measures) of the CVMSHCP should be implemented by the Project to minimize impacts to plant and wildlife species within the HCP’s jurisdiction (CVMSHCP, 2016).

The Project is outside of a designated Conservation Area, and a Joint Review Project is not required. However, the LDMF to the CVCC is required for development projects. Submission of the LDMF to the CVCC is recommended before building or grading permits are submitted.

Prior to construction and issuance of any grading permit for all projects covered in the IS/MND, the City shall ensure compliance with the CVMSHCP and its associated Implementing Agreement and shall ensure the collection of payment of the CVMSHCP Local Development Mitigation Fee and transfer of fees, at least quarterly and prior to impacts to Covered Species and their Habitats, to the Coachella Valley Conservation Commission.

A Qualified Archaeologist who meets or exceeds the Secretary of Interior’s Professional Qualification Standards for archaeology (NPS, 1983) shall conduct Workers Environmental Awareness Program (WEAP) training on archaeological sensitivity for all construction personnel prior to the commencement of any ground-disturbing activities. Archaeological sensitivity training shall include a description of the types of cultural material that may be encountered, cultural sensitivity issues, the regulatory environment, and the proper protocol for treatment of the materials in the event of a find. The WEAP training document shall include materials that convey the information noted above, which shall be maintained in an area accessible to all construction personnel so that it may be reviewed regularly by construction staff. • CR-2: Pre-Excavation Agreement
Prior to the issuance of Grading Permits, the Applicant/Owner shall enter into a pre-excavation agreement, otherwise known as a Tribal Cultural Resources Treatment and Tribal Monitoring Agreement with the consulting Tribal Monitor associated within the area. A copy of the agreement shall be included in building and development plans and permit applications with the City. The purpose of this agreement shall be to formalize protocols and procedures between the Applicant/Owner and the consulting Tribal Monitor associated with the area for the protection and treatment of, including but not limited to, Native American human remains, funerary objects, cultural and religious landscapes, ceremonial items, and traditional gathering areas and tribal cultural resources located and/or discovered through a monitoring program in conjunction with the construction of the proposed project, including additional archaeological surveys and/or studies, excavations, geotechnical investigations, grading, and all other ground disturbing activities. At the discretion of the consulting Tribal Monitor, artifacts may be made available for 3D scanning/printing, with scanned/printed materials to be curated at a local repository meeting the federal standards of 36CFR79.
• CR-3: Retention of Qualified Archaeologist and Tribal Monitor Prior to the issuance of a Grading Permits, the Applicant/Owner or Grading Contractor shall provide a written and signed letter to the City of La Quinta Planning Division stating that a Qualified Archaeologist and consulting Tribal Monitor have been retained at the Applicant/Owner or Grading Contractor’s expense to implement the monitoring program, as described in the pre-excavation agreement.
• CR-4: Tribal Cultural Monitor Coordination During Ground Disturbing Activities The Qualified Archaeologist and consulting Tribal Monitor shall attend all applicable pre-construction meetings with the General Contractor and/or associated subcontractors to present the archaeological monitoring program. The Qualified Archaeologist and consulting Tribal Monitor shall be present on-site full-time during grubbing, grading, and/or other ground altering activities, including the placement of imported fill materials or fill used from other areas of the Project site, to 413 Return to Agenda Link
Environmental Analysis
City of La Quinta Highway 111 Corridor Specific Plan 3-122 identify any evidence of potential archaeological or tribal cultural resources. All fill materials shall be absent of any and all tribal cultural resources.
• CR-5: Controlled Grade Procedure
To detect important archaeological artifacts and cultural resources during monitoring, a "Controlled Grade Procedure" must be created by a Qualified Archaeologist. This will be done in consultation with the consulting Tribal Monitor, relevant consulting Tribes, and the Applicant/Owner, and needs approval from City representatives. The procedure will set guidelines for machinery work in sensitive areas identified during cultural resource monitoring. It will cover aspects like operating speed, removal increments, weight, and equipment features. A copy of this procedure must be included in the Grading Plan submissions for Grading Permits.
• CR-6: Discovery of Tribal Cultural Resources
The Qualified Archaeologist and consulting Tribal Monitor can stop ground-disturbing activities undiscovered tribal cultural resources or artifacts are found. All work must cease in the vicinity of any archaeological discovery until the Qualified Archaeologist and Tribal Monitor can assess the context of the find, including its significance, potential eligibility for the California Register of Historical Resources (CRHR), and whether the project would have a direct impact on the resource.

If buried cultural deposits are encountered, the Archaeologist and Tribal Monitor may request that construction halt nearby and must notify a Qualified Archaeologist within 24 hours for investigation.

Work will be redirected away from these areas for assessment. Minor finds will be documented and secured for later repatriation; if items cannot be securely stored on-site, they may be stored off-site.

Minor finds include archaeological materials that are isolated, lack context, and are unlikely to indicate a larger or significant site. If the discovered resources are deemed potentially significant, the involved consulting Tribes will be notified for consultation on their respectful treatment.

Avoidance of significant resources is preferred, but if not feasible, a data recovery plan may be required. The consulting Tribes will be consulted on this plan as well.

For resources under a data recovery plan, a proper sample will be collected using professional methods, reflecting tribal values. The Tribal Monitor must be present during any resource collection or cataloging. If the Qualified Archaeologist does not collect the resources, the Tribal Monitor may do so. Ground-disturbing work will not resume until the resources are documented and/or protected. • CR-7: Treatment of Tribal Cultural Resources
The landowner shall relinquish ownership of all cultural resources unearthed during all ground disturbing activities, and from any previous archaeological studies or excavations on the Project site to the affiliated consulting Tribe, as determined through the appropriate process, for respectful and dignified treatment and disposition, including reburial at a protected location on-site, in accordance with the Tribe’s cultural and spiritual traditions. All cultural materials that are associated with burial and/or funerary goods would be repatriated to the Most Likely Descendant as determined by the NAHC per California Public Resources Code Section 5097.98. No tribal cultural resources shall be subject to curation.
• CR-8: Tribal Cultural Monitoring Report
A monitoring report and/or evaluation report, if appropriate, which describes the results, analysis, and conclusions of the archaeological monitoring program (e.g., data recovery plan) shall be 414 Return to Agenda Link
Environmental Analysis
City of La Quinta Highway 111 Corridor Specific Plan 3-123 submitted by the Qualified Archaeologist, along with the consulting Tribal Monitor’s notes and comments, to the City of La Quinta Planning Division for approval. • CR-9: Unanticipated Discovery of Human Remains
As specified by California Health and Safety Code Section 7050.5, if human remains are found on the Project site during construction or during archaeological work, the person responsible for the excavation, or his or her authorized representative, shall immediately notify the Riverside County Coroner’s Office by telephone. No further excavation or disturbance of the site or any nearby area reasonably suspected to overlie adjacent remains shall occur until the Coroner Medical Examiner has made the necessary findings as to origin and disposition pursuant to Public Resources Code 5097.98. If such a discovery occurs, a temporary construction exclusion zone shall be established surrounding the area of the discovery so that the area would be protected, and consultation and treatment could occur as prescribed by law. If suspected Native American remains are discovered, the remains shall be kept in-situ, or in a secure location in close proximity to where they were found, and the analysis of the remains shall only occur on-site in the presence of a consulting Tribal Monitor. By law, the Coroner Medical Examiner shall determine within two working days of being notified if the remains are subject to his or her authority. If the Coroner Medical Examiner identifies the remains to be of Native American ancestry, he or she shall contact the NAHC within 24 hours.

The NAHC shall make a determination as to the Most Likely Descendent. If human remains are discovered, notify the consulting Tribe’s Tribal Historic Preservation Officer. • AIR-1: Localized Significance Assessment
Prior to the issuance required discretionary permits, new development projects in the Specific Plan area, if subject to CEQA compliance, must demonstrate that the proposed development would either not exceed applicable the SCAQMD’s LST lookup tables or not exceed the respective ambient air quality thresholds for CO, NOX, and PM10 and PM2.5.
• GEO-1: Protect Paleontological Resources during Construction Activities Prior to ground disturbing activities, all field personnel will receive training on paleontological resources, including potential fossils that may be discovered and response steps, while a qualified paleontologist will prepare a Paleontological Resources Monitoring and Mitigation Plan (PRMMP).

If fossils (like bones, teeth, or well-preserved plants) are found during construction, the City will stop work within 50 feet and notify a paleontologist to document and assess the find. The paleontologist may allow work to continue or recommend salvaging the fossils if necessary and will suggest appropriate treatment methods. Collected fossils will be sent to an accredited institution for curation and preservation.

All earth-moving operations deeper than two feet must have a qualified paleontological monitor.

Continuous monitoring is needed if fossil-rich lakebed sediments are found. The monitor can stop work to identify and salvage fossils and may halt equipment for large specimens. A monitoring plan must be submitted to the City before any permits are issued or soil is disturbed. Grading and excavation must comply with La Quinta Code and regulations.

After ground disturbing activities and any necessary fossil curation, the project paleontologist will prepare a final report detailing the results of the PRMMP. 415 Return to Agenda Link

Highway 111 Corridor Specific Plan
Mitigation Monitoring and Reporting Program (MMRP)
The California Environmental Quality Act (CEQA) requires the adoption of feasible mitigation measures to reduce the severity and magnitude of potentially significant environmental impacts associated with project development.

CEQA Guidelines Section 15091(d) states:

When making the findings required in subdivision (a)(1), the CEQA Lead Agency shall also adopt a program for reporting on or monitoring the changes which it has either required in the project or made a condition of approval to avoid or substantially lessen significant environmental effects. These measures must be enforceable through permit conditions, agreements, or other measures.

CEQA Guidelines Section 15097(a) states:

This section applies when a public agency has made the findings required under paragraph (1) of subdivision (a) of section 15091 to adopt a mitigated negative declaration in conjunction with approving a project. In order to assure that the mitigation measures and project revisions identified in the negative declaration are implemented, the public agency shall adopt a program for monitoring or reporting on the revisions which it has required in the project and the measures it has imposed to mitigate or avoid significant environmental effects.

Biological Resources
BIO-1: Assessment of Biological Resources and Worker Environmental Awareness Training Prior to Project construction activities for all projects covered in this IS/MND, a complete and recent inventory of rare, threatened, endangered, and other sensitive species located within the Project footprint and within offsite areas with the potential to be affected, including California Species of Special Concern and California Fully Protected Species (Fish and Game Code § 3511), will be completed. Species to be addressed should include all those which meet the CEQA definition (CEQA Guidelines § 15380).

The inventory should address seasonal variations in use of the Project area and should not be limited to resident species.

Focused species-specific surveys, completed by a qualified biologist and conducted at the appropriate time of year and time of day when the sensitive species are active or otherwise identifiable are required. Acceptable species-specific survey procedures should be developed in consultation with CDFW and the U.S. Fish and Wildlife Service, where necessary. Note that CDFW generally considers biological field assessments for wildlife to be valid for a one-year period, and assessments for rare plants may be considered valid for a period of up to three years. Some aspects of the proposed Project may warrant periodic updated surveys for certain sensitive taxa, particularly if the Project is proposed to occur over a protracted time frame, or in phases, or if surveys are completed during periods of drought.

An environmental training program should be developed and presented by a qualified biologist to all crew members prior to the beginning of all Project construction in natural areas planned for development. The training should describe special-status plant and wildlife species and sensitive habitats that could occur within the Project area, protection afforded to these species and habitats, and avoidance and minimization measures required to avoid and/or minimize impacts from the project.

All new construction personnel should receive this training before beginning work on this Project. A copy of the training and training materials should be provided to construction crews for review and approval at least 30 days prior to the start of construction. As needed, in-field training should be provided to new on-site construction personnel by the qualified biologist or a qualified individual who should be identified by the qualified biologist, or initial training should be recorded and replayed for new personnel..

BIO-2: General Measures for Plants and Wildlife
When working in the natural habitat areas, the number of access routes, number and size of staging areas, and the total area of the activity should be limited to the minimum necessary to achieve the project goal. Routes and boundaries outside of normal access roads should be clearly delineated through fencing or flagging.

Food, trash, and other solid wastes should be disposed of in Common Raven proof/wildlife proof, covered refuse containers and regularly removed from the various structures and facilities on a daily basis to avoid offsite dispersal of waste and to avoid attracting wildlife onto the Project site. Following covered activity work, all trash and debris should be removed from the work area.

Construction work should avoid direct destruction of burrows through chaining (dragging a heavy chain over an area to remove shrubs), disking, cultivation, and urban, industrial, or agricultural development.

Project-related excavations greater than 6 inches deep should be secured to prevent wildlife entry and entrapment. Holes and trenches should be back-filled, securely covered, or fenced. Excavations that cannot be fully secured should incorporate appropriate wildlife ramp(s) at a slope of no more than a 3:1 ratio (horizontal: vertical, equivalent to a 33.3 percent or 18.4-degree slope), or other means to allow trapped animals to escape.

Personnel on site should be required to check under their vehicles for sensitive species prior to moving them and should exercise caution while driving on the Project site.

Before moving, burying, or capping, inspect for wildlife in any construction pipes, culverts, or similar structures that are stored on the site for one or more nights. Alternatively, cap structures before storing on the work site..

Conduct pre-construction surveys to
check for nesting activity no later than
14 days before Project activities begin.

BIO-3: Special Status and Migratory Birds
Construction should be conducted, if possible, during the fall and/or winter months and outside of the avian nesting season (generally February 1 – August 31) to avoid any direct and or indirect effects to protected nesting birds. Pre-construction surveys shall focus on both direct and indirect evidence of nesting, including nest locations and nesting behavior. The qualified avian biologist will make every effort to avoid potential nest predation as a result of survey and monitoring efforts. If active nests are found during the pre-construction nesting bird surveys, a qualified biologist shall establish an appropriate nest buffer to be marked on the ground. Nest buffers are species specific and shall be at least 100 feet for passerines and 300 feet for raptors. A smaller or larger buffer may be determined by the qualified biologist familiar with the nesting phenology of the nesting species and based on nest and buffer monitoring results. Construction activities may not occur inside the established buffers, which shall remain on-site until a qualified biologist determines the young have fledged or the nest is no longer active. Active nests and adequacy of the established buffer distance shall be monitored at least once a week or as needed by the qualified biologist until the qualified biologist has determined the young have fledged or the Project has been completed. The qualified biologist has the authority to stop work if nesting pairs exhibit signs of disturbance.

Pre-construction surveys, If active nests
or burrows are found within 500 feet of
construction, an ornithologist should
mark a buffer around them, and
construction should avoid these areas
until the young have fledged or nesting
activity has ended. Activities that may
disturb nesting shall be prohibited from
the buffer zone.

BIO-4: Burrowing Owl Surveys
No less than 60 days prior to the start of Project-related activities for all projects covered in the MND, a burrowing owl habitat assessment shall be conducted by a qualified biologist according to the specifications of the Staff Report on Burrowing Owl Mitigation (Department of Fish and Game, March 2012 or most recent version) for all projects covered under the MND.

If the habitat assessment demonstrates suitable burrowing owl habitat, then focused burrowing owl surveys shall be conducted by a qualified biologist in accordance with the Staff Report on Burrowing Owl Mitigation (2012 or most recent version) prior to vegetation removal or ground-disturbing activities. If burrowing owls are detected during the focused surveys, the qualified biologist and Project proponent shall begin coordination with CDFW and USFWS immediately, and shall prepare a Burrowing Owl Avoidance and Monitoring Plan that shall be submitted to CDFW for review and approval prior to commencing Project activities.

The Burrowing Owl Plan shall describe proposed avoidance and monitoring actions, including measures necessary to avoid take of burrowing owl individuals, nests, and eggs. The Burrowing Owl Plan shall include the number and location of occupied burrow sites (occupied site means at least one burrowing owl or its sign has been observed within the last three years; may be indicated by owl sign including feathers, pellets, prey remains, eggshell fragments, or excrement at or near a burrow entrance or perch site), acres of burrowing owl habitat that will be impacted, details of site monitoring, and details on proposed buffers and other avoidance measures. If impacts to occupied burrowing owl habitat or burrow(s) or burrowing owl individuals, nests, or eggs cannot be avoided, appropriate California Endangered Species Act (CESA) authorization (i.e., Incidental Take Permit under Fish and Game Code section 2081) should be obtained from CDFW prior to commencement of Project activities.

Preconstruction burrowing owl surveys shall be conducted no less than 14 days prior to the start of Project-related activities and within 24 hours prior to ground disturbance, in accordance with the Staff Report on Burrowing Owl Mitigation (2012 or most recent version). Preconstruction surveys should be repeated when there is a pause in construction of more than 30 days.

Preconstruction surveys should be performed by a qualified biologist following the recommendations and guidelines provided in the Staff Report on Burrowing Owl Mitigation. If the preconstruction surveys confirm occupied burrowing owl habitat, Project activities shall be immediately halted. The qualified biologist shall coordinate with CDFW and prepare a Burrowing Owl Avoidance and Monitoring Plan that shall be submitted to CDFW and USFWS for review and approval prior to commencing Project activities..

CR-6: Discovery of Tribal Cultural Resources
The Qualified Archaeologist and consulting Tribal Monitor can stop ground-disturbing activities if undiscovered tribal cultural resources or artifacts are found. All work must cease in the vicinity of any archaeological discovery until the Qualified Archaeologist and Tribal Monitor can assess the context of the find, including its significance, potential eligibility for the California Register of Historical Resources (CRHR), and whether the project would have a direct impact on the resource. If buried cultural deposits are encountered, the Archaeologist and Tribal Monitor may request that construction halt nearby and must notify a Qualified Archaeologist within 24 hours for investigation.

Work will be redirected away from these areas for assessment. Minor finds will be documented and secured for later repatriation; if items cannot be securely stored on-site, they may be stored off-site. Minor finds include archaeological materials that are isolated, lack context, and are unlikely to indicate a larger or significant site. If the discovered resources are deemed potentially significant, the involved Tribes will be notified for consultation on their respectful treatment. Avoidance of significant resources is preferred, but if not feasible, a data recovery plan may be required. The consulting Tribes will be consulted on this plan as well.

For resources under a data recovery plan, a proper sample will be collected using professional methods, reflecting tribal values.

The Tribal Monitor must be present during any resource collection or cataloging. If the Qualified Archaeologist does not collect the resources, the Tribal Monitor may do so. Ground-disturbing work will not resume until the resources are documented and/or protected.

GEO-1: Protect Paleontological Resources during Construction Activities Prior to ground disturbing activities, all field personnel will receive training on paleontological resources, including potential fossils that may be discovered and response steps, while a qualified paleontologist will prepare a Paleontological Resources Monitoring and Mitigation Plan (PRMMP).

If fossils (like bones, teeth, or well-preserved plants) are found during construction, the City will stop work within 50 feet and notify a paleontologist to document and assess the find. The paleontologist may allow work to continue or recommend salvaging the fossils if necessary and will suggest appropriate treatment methods. Collected fossils will be sent to an accredited institution for curation and preservation.

All earth-moving operations deeper than two feet must have a qualified paleontological monitor. Continuous monitoring is needed if fossil-rich lakebed sediments are found. The monitor can stop work to identify and salvage fossils and may halt equipment for large specimens. A monitoring plan must be submitted to the City before any permits are issued or soil is disturbed. Grading and excavation must comply with La Quinta Code and regulations.

After ground disturbing activities and any necessary fossil curation, the project paleontologist will prepare a final report detailing the results of the PRMMP.

Subject La Quinta 15-acre Mixed Use Development –
Biological Reconnaissance Site Visit to Support

CEQA IS/MND
Project no. 11219378
The City of La Quinta (City) is proposing a mixed-use development in La Quinta, California (hereafter Project). To assist with preparation of the Project’s Initial Study/Mitigated Negative Declaration (IS/MND) in accordance with the California Environmental Quality Act (CEQA), GHD evaluated the potential for sensitive biological resources (federal or state listed or state special status plants and wildlife, Sensitive Natural Communities, and wetlands) to occur within the Project area and potential impacts to these resources. Based on occurrence records, habitat availability, and the reconnaissance-level site visit, special status wildlife species have a potential to occur in the Project area. Special status plants may have the potential to occur but would require protocol-level surveys in appropriate blooming seasons to determine presence/absence. No impacts to jurisdictional wetlands or waters, or Sensitive Natural Communities are expected.

Regards,
Sara Moriarty-Graves
Wildlife Biologist

11219378 2

1. Introduction
The City of La Quinta (City) is proposing a mixed-use development in La Quinta, California (hereafter Project; Appendix A, Figure 1). The proposed Project plan includes development of up to 280 low-income apartment units along the north side of the parcel, and a commercial development on the south side of the parcel, along Highway 111. As part of the development, Corporate Center Drive would be extended to be continuous and separate the residential and commercial portions of the Project area.

The 280 residential units are proposed to be a mix of one, two and three bedrooms and would require approximately 350-375 parking spaces. The average unit would be about 850 square feet in area. The residential buildings would be four stories with the units accessed off of a central interior hallway. Each story would have approximately 62 or 63 units. The parking spaces would be provided in three levels of parking (two story structure with parking on the roof). Bridges would be provided to link the 2nd and 3rd levels of parking to the corresponding residential level. The complex would include common amenities such as a swimming pool, play structures, common areas, operational and maintenance offices, and trash rooms. The commercial development would provide an approximate 85,000 square foot large retail building and 15,000 square foot separate drive through building. The sizes and configuration may vary based on the final commercial establishments.

GHD evaluated the potential for sensitive biological resources (federally or state listed or state special status plants and wildlife, Sensitive Natural Communities [SNCs], and wetlands) to occur within the Project Study Boundary (PSB) and Biological Study Area (BSA; defined as the PSB and a 100-foot buffer to account for associated impacts from the Project; Appendix A, Figure 2). In addition, potential Project impacts to these resources were evaluated.

Special status species and resources are the primary focus of this evaluation. Common species or resources without special protections are not considered. The purpose of this biological reconnaissance technical memorandum is to document the results of the February 4, 2023, site visit and provide information to support the Project’s Initial Study/Mitigated Negative Declaration (IS/MND) in accordance with the California Environmental Quality Act (CEQA) to provide a programmatic-level review of potential environmental impacts associated with the proposed Project.

1.1 Project Location and Existing Setting
The BSA is located in the City of La Quinta, which is in the County of Riverside, in between Highway 111 and the Whitewater River (Appendix A, Figure 2). Land cover is classified as shrub/scrub and is surrounded by open developed space to high level of intensity (USGS 2016).

The City is located in the Coachella Valley, which is in between the Santa Rosa Mountains and Jacinto Mountains (to the west), Joshua Tree National Park (to the east), and approximately 40 miles from the Salton Sea (to the southeast). The BSA is located within the Whitewater River Watershed. The PSB is 15 acres, and is surrounded by retail stores, businesses, Highway 111, and other roads. The northern section of the BSA borders the Whitewater River. The landscape surrounding the BSA is highly urbanized and developed, with high amounts of vehicular traffic.

2. Survey Methods
The following subsections summarize the desktop and field methods utilized to produce this technical memorandum.

2.1 Database Searches (CNDDB, CNPS, EFH, IPaC, NOAA Critical Habitat, and NWI)
A database search for sensitive biological resource records in the Project vicinity was conducted by GHD on January 24, 2023. Database searches (Appendix B) included the California Natural Diversity Database (CNDDB; CDFW 2023a), California Native Plant Society (CNPS) Inventory of Rare and Endangered 433 Return to Agenda Link
11219378 3
Vascular Plants (CNPS 2023), U.S. Fish and Wildlife Service (USFWS) Information for Planning and Consultation (IPaC; USFWS 2023), National Oceanic and Atmospheric (NOAA) Fisheries Essential Fish Habitat (EFH; NOAA 2023a), and NOAA Critical Habitat (NOAA 2023b).

The search encompassed the La Quinta U.S. Geological Survey 7.5-minute quadrangle and surrounding eight quads (Rancho Mirage, Cathedral City, Myoma, West Berdoo Canyon, Indio, Valerie, Martinez Mountain, and Toro Peak). Appendix A, Figure 3 shows all special status species records tracked by the CNDDB that are known to occur within a three-mile radius of the Project. A search of the USFWS National Wetlands Inventory (NWI) for the Project vicinity was completed on January 24, 2023 (Appendix A, Figure 4; USFWS 2023b).

2.2 Field Survey
A reconnaissance field survey was conducted by Sara Moriarty-Graves, GHD Wildlife Biologist, on February 4, 2023, from 09:30 to 11:00. Weather conditions were clear and with light air (Beaufort scale 1), about 60 to 65 degrees Fahrenheit. The survey included walking the entire PSB (Appendix A, Figure 2).

The BSA was assessed visually from the public street right-of-way. The survey methods were intended to assess the potential for special status resources and habitats that occur within the BSA. The survey involved a physical search of the area, including visual inspections of the ground, holes, and vegetation for the presence of any wildlife species, special status plant species, or SNCs. Additionally, the bark of vegetation and the ground layer under vegetation were visually inspected for evidence of wildlife species, such as feathers, pellets, whitewash, scat, tracks, etc. No protocol-level surveys for wetlands, SNCs, special status plants, or wildlife were conducted.

3. Results
The following sub-sections summarize the results of the desktop research and field survey performed for this technical memorandum.

3.1 Summary of General Biological Resources
The PSB is a vacant lot located within the city of La Quinta and is surrounded by commercial businesses.

There was litter, and signs of foot traffic and vehicle use observed within the BSA. The dominant vegetation within the PSB consisted of creosote (Larrea tridentata). The BSA is bordered to the north by the channelized Whitewater River. No flowing water and minimal moisture within the riverbed was observed.

Commercial businesses surround the BSA to the east, south, and west. The other side of the Whitewater River is also developed.

Although the BSA is within a developed landscape, there are shrubs and dune habitat that may support special status species. Many small mammal burrows were observed within the BSA, which can be used by other taxa such as birds and reptiles. The BSA also supports common avian species protected by the federal Migratory Bird Treaty Act (MBTA) and California Fish and Game Code (FGC). Photos from the site visit are included in Appendix C (Site Visit Photos). Lists of all species observed within the BSA are provided in Appendix D, Tables D1 to D4.

3.2 Wetlands and Waters
The Whitewater River is adjacent to the northern portion of the BSA. The section of river adjacent to the BSA is classified as a riverine intermittent streambed that is intermittently flooded (USFWS 2023b).

However, the Whitewater River in the Project vicinity is channelized and is highly modified from its original form. To reduce sedimentation and maintain flows, it is frequently maintained by the Coachella Valley Water District (City of La Quinta 2017). It is characterized as having a mixture of earthen and concrete bottom and slopes and supports some vegetation growth. The channel conveys surface storm water runoff during rain events (City of La Quinta 2017). During the site visit, there was limited puddled water observed within the river (Appendix C, Site Visit Photos). No flowing water was observed, and there were signs of vehicular use within the riverbed.
434 Return to Agenda Link
11219378 4
The Project does not involve alteration of the Whitewater River, including the channel and floodplain. There will be no impact to the Whitewater River or jurisdictional wetlands.

3.3 Sensitive Natural Communities (SNCs)
A query of CNDDB returned multiple locations of Desert Fan Palm Oasis Woodland (Washingtonia filifera) SNC (G3, S3.2) in the nine quads surrounding the PSB; however, the nearest Desert Fan Palm Oasis to the PSB is over five miles to the northeast. No native fan palms are present in the PSB.

The PSB is mainly vegetated by Creosote Bush Scrub (Larrea tridentata), a natural community which is not considered sensitive by CDFW (G5, S5).

The Project would not impact any SNCs, as none are present.

3.4 Habitat Conservation Plans and Natural Community
Conservation Plans
Habitat Conservation Plans (HCPs) and Natural Community Conservation Plans (NCCPs) are site-specific plans to address effects on sensitive species of plants and animals. The BSA is within the Coachella Valley Multiple Species Habitat Conservation Plan (CVMSHCP), which is an HCP and NCCP implemented by the Coachella Valley Conservation Commission (CVCC; CDFW 2023b, CVCC 2023). The City of La Quinta has been a participant in the CVMSHCP since 1996. If the project qualifies, the signatories to the CVMSHCP are able to obtain coverage for incidental take for the 21 wildlife and plant species that the CVMSHCP covers (CVCC 2023).

The Project is outside of a designated Conservation Area, and a Joint Review Project is not required.

However, the Local Development Mitigation Fee (LDMF) to the CVCC is required for development projects.

Submission of the LDMF to the CVCC is recommended before building or grading permits are submitted.

3.5 Critical Habitat
The BSA does not overlap any federally designated critical habitat (Appendix B, IPaC Report). No impact would result.

3.6 Habitat Connectivity and Access
Wildlife corridors refer to established migration routes commonly used by resident and migratory species for passage from one geographic location to another. Maintaining the continuity of established wildlife corridors is important to: a) sustain species with specific foraging requirements, b) preserve a species’ distribution potential, and c) retain diversity among many wildlife populations. Therefore, resource agencies consider wildlife corridors to be a sensitive resource.

The Project is approximately seven miles from the nearest “essential connectivity area” and one mile from a “natural landscape block” and “small natural landscape area” identified by the California Habitat Connectivity Project (CDFW 2022c). The BSA is surrounded by existing development, Highway 111, and the highly modified Whitewater River. Due to the level of development existing surrounding the BSA, there would be no impact to the habitat access, connectivity, or migratory corridors of wildlife species. Habitat in the Project vicinity is highly fragmented. No new barriers to terrestrial wildlife movement would result from the Project, and the Project would not substantially interfere with migratory birds, bats, or other species.

3.7 Special Status Plants
The database scoping detailed in Section 2.1 produced a total of 66 plant species known to occur in the nine USGS quads surrounding the PSB. Based on species specific habitat requirements and habitat availability within the PSB, three species have a low potential to occur, and seven have a moderate potential to occur (Table 1). Due to the disturbed and isolated nature of the habitat in the PSB, no special status plant species have a high potential to occur.

No special status plant species were observed during the site visit on February 4, 2023; however, no protocol level surveys have been conducted and the site visit was outside of the blooming season for some 435 Return to Agenda Link

3.8 Special Status Wildlife
The database scoping detailed in Section 2.1 returned a total of 86 species (Table 2). The potential for sensitive wildlife species to occur was determined based on existing data and the reconnaissance level site visit. Special status species are federally and/or state listed, a CDFW Species of Special Concern, CDFW Fully Protected, on the CDFW Special Animals List, or any combination of these.

The Coachella Valley Fringe-toed Lizard (federally threatened and state endangered) is a listed reptile species with a moderate potential to occur within the BSA based on recent nearby observations (iNaturalist 2023). In addition, there is one special status rodent species (Coachella Valley Round-tailed Ground Squirrel), six bird species, one other reptile species (Flat-tailed Horned Lizard), and one insect (Coachella Valley Giant Sand Treader Cricket) with a moderate potential to occur (Table 2). The Burrowing Owl is a covered species under the CVMSHCP, but is afforded additional protections under FGC and the MBTA and would require additional minimization measures. According to the CVMSHCP, authorization of take for all species with a moderate potential to occur, except the six bird species, can be obtained through compliance with the CVMSHCP and the LDMF paid to the CVCC (CVCC 2023). Minimization measures to reduce impacts to bird species are included in Section 5. Although compliance with the CVMSHCP authorizes take for the covered species, state and federal regulations could require additional minimization measures in subsequent review of CEQA documents.

Terrestrial wildlife observed on site are included in Appendix D, Table D2. A lizard and ground squirrel were briefly observed during the site visit and were not able to be identified to species. A list of all bird species detected during the site visit and their associated breeding codes are presented in Appendix D, Tables D3 and D4. As many neotropical avian species have migrated south by fall, Table D4 is not a comprehensive list of all species that could occur throughout the breeding season. In addition, no protocollevel surveys have been conducted.

Based on existing habitat and available data, the BSA may support special status species and does support common species. With implementation of the proposed avoidance and minimization measures (Section 5), in addition to compliance with the CVMSHCP, impacts to special status wildlife species would be less than significant.

Other Statuses (other federal or state listings may include):

CDFW FP (CDFW Fully Protected Animal): “This classification was the State of California's initial effort to identify and provide additional protection to those animals that were rare or faced possible extinction. Lists were created for fish, amphibians and reptiles, birds and mammals. Most of the species on these lists have subsequently been listed under the state and/or federal endangered species acts.” (CDFW 2023c); CDFW SSC (CDFW Species of Special Concern): “It is the goal and responsibility of the Department of Fish and Wildlife to maintain viable populations of all native species. To this end, the Department has designated certain vertebrate species as ‘Species of Special Concern’ because declining population levels, limited ranges, and/or continuing threats have made them vulnerable to extinction. The goal of designating species as ‘Species of Special Concern’ is to halt or reverse their decline by calling attention to their plight and addressing the issues of concern early enough to secure their long-term viability” (CDFW 2023c); CDFW WL (California Department of Fish and Wildlife Watch List): “The CDFW maintains a list consisting of taxa that were previously designated as "Species of Special Concern" but no longer merit that status, or which do not yet meet SSC criteria, but for which there is concern and a need for additional information to clarify status” (CDFW 2023c).

Potential to Occur:

No potential: Habitat in and adjacent to the PSB is clearly unsuitable for the species requirements (cover, substrate, elevation, hydrology, plant community, site history, disturbance regime).

Low potential: Few of the habitat components meeting the species requirements are present, and/or the majority of habitat on and adjacent to the site is unsuitable or of very poor quality. The species is not likely to be found in the PSB.

Moderate potential: Some of the habitat components meeting the species requirements are present, and/or only some of the habitat on or adjacent to the site is unsuitable. The species has a moderate probability of being found in the PSB.

High potential: All of the habitat components meeting the species requirements are present and/or most of the habitat on or adjacent to the site is highly suitable. The species has a high probability of being found on in the PSB.

Present: Detected or documented on-site.

4. Discussion
Based on the reconnaissance-level site visit on February 4, 2023, and review of existing data, the BSA may provide suitable habitat for special status wildlife species. In addition, several common avian species were observed on-site that are protected by the MBTA and FGC (Appendix D, Table D2 and D4). Vegetation within and directly adjacent to the BSA could provide suitable nesting habitat for migratory bird species, and other common terrestrial species.

No special status plant species were observed during the site visit on February 4, 2023 (Appendix D, Table D1); however, no protocol level surveys have been conducted and the site visit was outside of the blooming season for some plant species with potential to occur in the PSB. Protocol level surveys will be required to determine if special status plants are present. No SNCs were observed during the site visit.

Since the Project is within the CVMSHCP’s boundaries, and within an authorized take area, mitigation for four special status species would be accounted for with compliance with the CVMSHCP and through purchase of LDMF’s from the CVCC (CVCC 2023). However, the CVMSHCP does not cover the six special status bird species with a moderate potential to occur, nor birds protected by the MBTA and FGC.

Additional measures are recommended in Section 5 for these bird species.

5. Proposed Avoidance and Minimization Measures
All Conservation Measures that are applicable within Section 4.4 (Required Avoidance, Minimization, and Mitigation Measures) and Section 9 (Species Accounts and Conservation Measures) of the CVMSHCP should be implemented by the Project to minimize impacts to plant and wildlife species within the HCP’s jurisdiction (CVMSHCP 2016). Specifically, species with a moderate potential to occur that are encompassed within the CVMSHCP include: Palm Springs Round-tailed Ground Squirrel, Burrowing Owl, Flat-tailed Horned Lizard, Coachella Valley Fringe-tailed Lizard, and the Coachella Giant Sand Treader Cricket (CDFW 2023b).

In addition, the following measures are recommended for implementation to reduce impacts to a less than significant level.

5.1 Measure BIO-1: Worker Environmental Awareness Training An environmental training program should be developed and presented by a qualified biologist to all crew members prior to the beginning of all Project construction. The training should describe special-status plant and wildlife species and sensitive habitats that could occur within the BSA, protection afforded to these species and habitats, and avoidance and minimization measures required to avoid and/or minimize impacts from the project.

All new construction personnel should receive this training before beginning work on this project. A copy of the training and training materials should be provided to construction crew for review and approval at least 30 days prior to the start of construction. As needed, in-field training should be provided to new on-site construction personnel by the qualified biologist or a qualified individual who should be identified by the qualified biologist, or initial training should be recorded and replayed for new personnel.

5.2 Measure BIO-2: Protect Special Status Plants
Avoidance measures for special status plant species are addressed collectively for all species. Impacts to special-status plant species present or likely to be present onsite shall be minimized, avoided, and (if necessary) compensated by complying with the following:
- Seasonally appropriate pre-construction surveys for special status plant species should occur prior to construction within the planned area of disturbance for the project, during the appropriate blooming time (spring and summer) for the target species. Survey methods should comply with CDFW rare plant survey protocols and should be performed by a qualified field botanist. Surveys 464 Return to Agenda Link
11219378 34
should be modified to include detection of juvenile (pre-flowering) colonies of perennial species when necessary. Any populations of special status plant species that are detected should be mapped. Populations should be flagged if avoidance is feasible and if populations are located adjacent to construction areas.
- The locations of any special status plant populations to be avoided should be clearly identified in the contract documents (plans and specifications).
- If special status plant populations are detected where construction would have unavoidable impacts, a compensatory conservation plan should be prepared and implemented in coordination with CDFW. Such plans may include salvage, propagation, on-site reintroduction in restored habitats, and monitoring.

5.3 Measure Bio-3: General Measures for Plants and Wildlife - When working in the dune habitat areas, the number of access routes, number and size of staging areas, and the total area of the activity should be limited to the minimum necessary to achieve the project goal. Routes and boundaries outside of normal access roads should be clearly delineated through fencing or flagging.
- Food, trash, and other solid wastes should be disposed of in Common Raven proof/wildlife proof, covered refuse containers and regularly removed from the various structures and facilities on a daily basis to avoid offsite dispersal of waste and to avoid attracting wildlife onto the project site.

Following covered activity work, all trash and debris should be removed from the work area. - Construction work should avoid direct destruction of burrows through chaining (dragging a heavy chain over an area to remove shrubs), disking, cultivation, and urban, industrial, or agricultural development.
- Project-related excavations greater than 6 inches deep should be secured to prevent wildlife entry and entrapment. Holes and trenches should be back-filled, securely covered, or fenced.

Excavations that cannot be fully secured should incorporate appropriate wildlife ramp(s) at a slope of no more than a 3:1 ratio (horizontal: vertical, equivalent to a 33.3 percent or 18.4-degree slope), or other means to allow trapped animals to escape.
- Personnel on site should be required to check under their vehicles for sensitive species prior to moving them and should exercise caution while driving on the Project site. - Before moving, burying, or capping, inspect for wildlife in any construction pipes, culverts, or similar structures that are stored on the site for 1 or more nights. Alternatively, cap structures before storing on the work site.

5.4 Measure Bio-4: Special Status and Migratory Birds
Potential Project impacts to six special status birds and common birds protected by the MBTA and FGC during construction may include visual disturbance, habitat destruction, and noise disturbance. The following measures are proposed to avoid potential impacts. - Construction should be conducted, if possible, during the fall and/or winter months and outside of the avian nesting season (generally February 1 – August 31) to avoid any direct effects to protected birds.
- A qualified ornithologist should conduct pre-construction surveys within the vicinity of the BSA, to check for nesting or burrowing activity of native birds and to evaluate the site for presence of raptors and special status bird species. The ornithologist should conduct at minimum a one-day pre-construction survey within the seven-day period prior to construction activities beginning. If construction work lapses for seven days or longer during the breeding season, a qualified ornithologist should conduct a supplemental avian pre-construction survey before Project work is reinitiated.
- If active nests or burrows are detected within the construction footprint or up to 500 feet from construction activities, the ornithologist should flag a buffer around each nest (assuming property access). Construction activities should avoid nest or burrows sites until the ornithologist determines 465 Return to Agenda Link
11219378 35
that the young have fledged or nesting activity has ceased. If nests or burrows are documented outside of the construction (disturbance) footprint, but within 500 feet of the construction area, buffers would be implemented as needed (buffer size dependent on species). Buffer sizes for common species would be determined on a case-by-case basis in consultation with the CDFW and, if applicable, with USFWS. Buffer sizes would consider factors such as:
• (1) noise and human disturbance levels at the construction site at the time of the survey and the noise and disturbance expected during the construction activity; • (2) distance and amount of vegetation or other screening between the construction site and the nest; and
• (3) sensitivity of individual nesting species and behaviours of the nesting birds. - If active nests or burrows are detected during the survey, the qualified ornithologist should monitor all nests or burrows at least once per week to determine whether birds are being disturbed.

Activities that might, in the opinion of the qualified ornithologist, disturb nesting activities (e.g., excessive noise), should be prohibited within the buffer zone until such a determination is made. If signs of disturbance or distress are observed, the qualified ornithologist should immediately implement adaptive measures to reduce disturbance. These measures may include, but are not limited to, increasing buffer size, halting disruptive construction activities in the vicinity of the nest until fledging is confirmed or nesting activity has ceased, placement of visual screens or sound dampening structures between the nest and construction activity, reducing speed limits, replacing and updating noisy equipment, queuing trucks to distribute idling noise, locating vehicle access points and loading and shipping facilities away from noise-sensitive receptors, reducing the number of noisy construction activities occurring simultaneously, and/or reorienting and/or relocating construction equipment to minimize noise at noise-sensitive receptors. - If Burrowing Owls are detected, buffers following guidance from Section 4 of the CHMSHCP would be adopted. The buffer distance during the non-breeding season is 160 feet, and 250 feet during the breeding season. Buffers would be staked and flagged. No Project work would be permitted within the established buffered distances. No development or operation and maintenance activities would be permitted within the buffer until the young are no longer dependent on the burrow. If the burrow is unoccupied, the burrow could be made inaccessible to owls, and the Covered Activity may proceed.

6. Conclusion
Based on occurrence records, habitat availability, and the reconnaissance-level site visit, special status wildlife and plant species may occur within the BSA. With compliance with the CVMSHCP (see Section

3.4), and the recommended minimization measures in Section 5, impacts are expected to be less than significant. The minimization measures are recommended to be implemented within the Project’s IS/MND document and associated Mitigation Monitoring and Reporting Program.

Project Code: 2023-0037535
Project Name: La Quinta PW HWY 111 Planning and Engineering Project Subject: List of threatened and endangered species that may occur in your proposed project location or may be affected by your proposed project
To Whom It May Concern:

The enclosed species list identifies threatened, endangered, proposed and candidate species, as well as proposed and final designated critical habitat, that may occur within the boundary of your proposed project and/or may be affected by your proposed project. The species list fulfills the requirements of the U.S. Fish and Wildlife Service (Service) under section 7(c) of the Endangered Species Act (Act) of 1973, as amended (16 U.S.C. 1531 et seq.).

New information based on updated surveys, changes in the abundance and distribution of species, changed habitat conditions, or other factors could change this list. Please feel free to contact us if you need more current information or assistance regarding the potential impacts to federally proposed, listed, and candidate species and federally designated and proposed critical habitat. Please note that under 50 CFR 402.12(e) of the regulations implementing section 7 of the Act, the accuracy of this species list should be verified after 90 days. This verification can be completed formally or informally as desired. The Service recommends that verification be completed by visiting the ECOS-IPaC website at regular intervals during project planning and implementation for updates to species lists and information. An updated list may be requested through the ECOS-IPaC system by completing the same process used to receive the enclosed list.

The purpose of the Act is to provide a means whereby threatened and endangered species and the ecosystems upon which they depend may be conserved. Under sections 7(a)(1) and 7(a)(2) of the Act and its implementing regulations (50 CFR 402 et seq.), Federal agencies are required to utilize their authorities to carry out programs for the conservation of threatened and endangered species and to determine whether projects may affect threatened and endangered species and/or designated critical habitat.

A biological assessment is required for construction projects (or other undertakings having similar physical impacts) that are major Federal actions significantly affecting the quality of the human environment as defined in the National Environmental Policy Act (42 U.S.C. 4332(2) (c)). For projects other than major construction activities, the Service suggests that a biological 503 Return to Agenda Link
01/24/2023   2
evaluation similar to a biological assessment be prepared to determine whether the project may affect listed or proposed species and/or designated or proposed critical habitat. Recommended contents of a biological assessment are described at 50 CFR 402.12.

If a Federal agency determines, based on the Biological Assessment or biological evaluation, that listed species and/or designated critical habitat may be affected by the proposed project, the agency is required to consult with the Service pursuant to 50 CFR 402. In addition, the Service recommends that candidate species, proposed species and proposed critical habitat be addressed within the consultation. More information on the regulations and procedures for section 7 consultation, including the role of permit or license applicants, can be found at the Fish and Wildlife Service's Endangered Species Consultation website at:
https://www.fws.gov/endangered/what-we-do/faq.html
Migratory Birds: In addition to responsibilities to protect threatened and endangered species under the Endangered Species Act (ESA), there are additional responsibilities under the Migratory Bird Treaty Act (MBTA) and the Bald and Golden Eagle Protection Act (BGEPA) to protect native birds from project-related impacts. Any activity, intentional or unintentional, resulting in take of migratory birds, including eagles, is prohibited unless otherwise permitted by the U.S. Fish and Wildlife Service (50 C.F.R. Sec. 10.12 and 16 U.S.C. Sec. 668(a)). For more information regarding these Acts see https://www.fws.gov/birds/policies-and-regulations.php.

The MBTA has no provision for allowing take of migratory birds that may be unintentionally killed or injured by otherwise lawful activities. It is the responsibility of the project proponent to comply with these Acts by identifying potential impacts to migratory birds and eagles within applicable NEPA documents (when there is a federal nexus) or a Bird/Eagle Conservation Plan (when there is no federal nexus). Proponents should implement conservation measures to avoid or minimize the production of project-related stressors or minimize the exposure of birds and their resources to the project-related stressors. For more information on avian stressors and recommended conservation measures see https://www.fws.gov/birds/bird-enthusiasts/threats-tobirds.php.

In addition to MBTA and BGEPA, Executive Order 13186: Responsibilities of Federal Agencies to Protect Migratory Birds, obligates all Federal agencies that engage in or authorize activities that might affect migratory birds, to minimize those effects and encourage conservation measures that will improve bird populations. Executive Order 13186 provides for the protection of both migratory birds and migratory bird habitat. For information regarding the implementation of Executive Order 13186, please visit https://www.fws.gov/birds/policies-and-regulations/ executive-orders/e0-13186.php.

We appreciate your concern for threatened and endangered species. The Service encourages Federal agencies to include conservation of threatened and endangered species into their project planning to further the purposes of the Act. Please include the Consultation Code in the header of this letter with any request for consultation or correspondence about your project that you submit to our office.

1. Endangered Species Act Species
There is a total of 8 threatened, endangered, or candidate species on this species list.

Species on this list should be considered in an effects analysis for your project and could include species that exist in another geographic area. For example, certain fish may appear on the species list because a project could affect downstream species.

IPaC does not display listed species or critical habitats under the sole jurisdiction of NOAA Fisheries , as USFWS does not have the authority to speak on behalf of NOAA and the Department of Commerce.

See the "Critical habitats" section below for those critical habitats that lie wholly or partially within your project area under this office's jurisdiction. Please contact the designated FWS office if you have questions.

Re: Cultural Resources Records Search for City of La Quinta Highway 111 Corridor Specific Plan Project
Dear Ryder Burliss,
We received your request on November 28, 2023, for a cultural resources records search for the City of La Quinta Highway 111 Corridor Specific Plan project, located in Sections 19, 30, 29, and 28, T.5S, R.7E, SBBM, in the southern area of the Whitewater River in the City of La Quinta in Riverside County. We have reviewed our maps, records, and reports against the project area defined on the map you provided.

Our records indicate that 92 cultural resource studies have been conducted within your project area.

Fifty-six cultural resource properties are recorded within the boundaries of the project area.

Additional sources of information consulted are identified below.

National Register of Historic Places (NRHP): no listed properties are located within the boundaries of the project area.

California Office of Historic Preservation (OHP), Archaeological Resources Directory (ARD): One property is listed as determined eligible for listing in the NRHP (P-33-001178 [CA-RIV-001178] La Quinta Evac. CH. AD.)
California Office of Historic Preservation (OHP), Built Environment Resources Directory (BERD): Two properties are listed as recognized as a historically significant by local government (P-33-007263, PT.

Happy Ranch and P-33-023955, PT. Happy Ranch). One property is listed as not eligible for listing or designation as specified (P-33-017259, Coachella Valley Stormwater Channel). One property is listed as not evaluated for NRHP or CRHR or needs revaluation (P-33-007264, 46370 Cameo Palms Dr).

Note: not all properties in the California Historical Resources Information System are listed in the OHP ARD and BERD; the ARD and BERD comprise lists of properties submitted to the OHP for review. 526 Return to Agenda Link
The 1941 USGS Toro Peak 15' minute series, 1959 USGS La Quinta 7.5' minute series, and 1959 USGS Palm Desert 15' minute series topographic maps show about 30 historical structures or features present within the boundaries of the project area.

Based on the information reviewed, 56 cultural resources properties have been recorded within the boundaries of the project area, thus additional cultural resources may be present within the boundaries of the project area. It is recommended that these resources undergo an evaluation of their significance to determine appropriate mitigation measures. However, this assessment does not rule out the possible presence of previously unidentified cultural resources, thus, it is recommended that the project area be examined systematically by a cultural resource professional to identify all historical, archaeological, and cultural heritage resources that have not been recorded, and to provide recommendations regarding their significance and management prior to any development of the project area. Persons involved in development of the project area should be sensitive to the significant and irreplaceable nature of cultural resources. A statewide list of cultural resources consultants can be found online at http://chrisinfo.org.

State and federal law requires that if any cultural resources are found during construction, work is to stop and the lead agency and a cultural resources professional be consulted to determine the importance of the find and its appropriate management.

Due to processing delays and other factors, not all of the historical resource reports and resource records that have been submitted to the Office of Historic Preservation are available via this records search.

Additional information may be available through the federal, state, and local agencies that produced or paid for historical resource management work in the search area. Additionally, Native American tribes have historical resource information not in the California Historical Resources Information System (CHRIS) Inventory, and you should contact the California Native American Heritage Commission for information on local/regional tribal contacts.

The California Office of Historic Preservation (OHP) contracts with the California Historical Resources Information System's (CHRIS) regional Information Centers (ICs) to maintain information in the CHRIS inventory and make it available to local, state, and federal agencies, cultural resource professionals, Native American tribes, researchers, and the public. Recommendations made by the IC coordinators or their staff regarding the interpretation and application of this information are advisory only. Such recommendations do not necessarily represent the evaluation or opinion of the State Historic Preservation Officer in carrying out the OHP' s regulatory authority under federal and state law.
