The plan was prepared pursuant to the requirements of the Disaster Mitigation Act of 2000 to achieve eligibility and potentially secure mitigation funding through Federal Emergency Management Agency (FEMA) Flood Mitigation Assistance, Pre -Disaster Mitigation, and Hazard Mitigation Grant Programs. The City of La Quinta's continual efforts to maintain a disaster -mitigation strategy are - ongoing. Our goal is to develop and maintain an all-inclusive plan to include all jurisdictions, special districts, businesses, and community organizations to promote consistency, continuity, and unification. The City of La Quinta's planning process followed a methodology presented by FEMA and CaLOES, which included conducting meetings with the Operational Area Planning Committee (OAPC) coordinated by Riverside County Emergency Management Department (EMD) comprised of participating Federal, State, and local jurisdictions agencies, special districts, school districts, non-profit communities, universities, businesses, tribes, and general public. The plan identifies vulnerabilities, provides recommendations for prioritized mitigation actions, evaluates resources, identifies mitigation shortcomings, and provides future mitigation planning and maintenance of existing plans. The plan will be implemented upon FEMA approval. 3 LOCAL HAZARD MITIGATION PLAN 12/21/2023 TABLE OF CONTENTS CONTACTINFORMATION.........................................................................................................................................................1 PLAN ADOPTION/RESOLUTION............................................................................................................................................ 2 EXECUTIVESUMMARY............................................................................................................................................................... 3 TABLEOF CONTENTS.................................................................................................................................................................4 SECTION 1.0 -

La Quinta is situated approximately 150 miles northeast of San Diego and 130 miles east of Los Angeles on the desert floor of the Coachella Valley. The valley is flanked on three sides by the Little San Bernardino, Santa Rosa, and San Jacinto Mountains. The protection afforded by the mountains contributes to the arid climate. Average rainfall per year is less than 5 inches total. Low temperatures rarely drop below freezing, while highs during the summer are usually in the triple digits and can reach 120 F degrees: however, it's a "dry" heat. Visitors from colder climates flock to La Quinta and surrounding cities in the Coachella Valley from November to May because of our extremely mild winters. La Quinta's climate can be described as Lower California desert. 6 LOCAL HAZARD MITIGATION PLAN 12/21/2023 1.2 BRIEF HISTORY The City of La Quinta was organized, formed, and incorporated under the laws of the State of California on May 1, 1982. In 1996, La Quinta voters passed a measure changing the City's status from a general law city to a charter city having the right of governance over its municipal affairs. It has a "Council -Manager" form of government where the City Manager is appointed by the City Council and is the Chief Executive Officer of the Municipal Corporation. The Council acts as the board of directors of the municipal corporation and meets in a public forum where citizens may participate in the governmental process. The City Council consists of five members elected at -large, on a non -partisan basis. Residents elect the Mayor and four Council members, making each accountable to the entire citizenry. 1.3 ECONOMY DESCRIPTION The City of La Quinta, California is a mixed community of residential and businesses with a 2021 population of 37,800 and growing. La Quinta is located about 20 miles east of Palm Springs, California along Highway 111 in the Coachella Valley. The median age of residents is 49.6 years and the median household income is $83,412.

Retail is an integral component in the sustainability of La Quinta's economy through the generation of sales tax revenue. La Quinta's portfolio of hotels & lodges is composed of 18 properties. The mild winters, surrounding beauty, and high profile festivals also generate tax revenue, such as Transient Occupancy Tax, which supplements the economy. La Quinta's unemployment rate of 3.2% in November of 2022 according to the Bureau of Labor Statistics. Historically, La Quinta's unemployment rate has stayed below the national average. 7 LOCAL HAZARD MITIGATION PLAN 12/21/2023 1.4 POPULATION AND HOUSING The population of the City of La Quinta, California is estimated at 37,846 in 2021, according to Data USA and SCAG, a website that pulls its facts from various public US Government datasets.

While the previous table breaks down cost burden by area -relative income, the AC5 also allows for the analysis of La Quinta's 3,990 renter households (for which income data are available) by spending on rent by income bracket (dollar amounts). As one might expect, the general trend is that low-income households spend a higher share of income on housing (e.g. over 50%) while high - income households are more likely to spend under 20% of income on housing. 1.S BRIEF STATEMENT OF UNIQUE HAZARDS The most prominent hazards facing the city of La Quinta residents are Drought Earthquakes, Flooding, and Extreme Heat. The proximity of Interstate 10 and the Union Pacific Railroad increases the risk of hazardous materials transportation spills or releases during any of these natural disasters listed. A power outage in the summer could cause life - threatening conditions for those without power or access to air conditioning. Additionally the City of La Quinta may be impacted by a terrorist attack. 1.6 DEVELOPMENT TRENDS AND LAND USE The City of La Quinta seeks to maximize land use to stimulate economic development, expand the hotel/resort/hospitality industry, and support opportunities to create a full spectrum housing inventory. La Quinta, in conjunction with SilverRock Development Company, LLC, has created a development program for SilverRock Resort. The program includes a luxury hotel with branded luxury residential, a lifestyle hotel with branded lifestyle residential, a mixed -use village, a golf clubhouse, and associated road and utility infrastructure. This $420 million dollar project commenced in May 2017. This project was rebranded as the Talus La Quinta in 2021, with the inclusion of two luxury hotels as well as dozens of private homes. In 11 LOCAL HAZARD MITIGATION PLAN 12/21/2023 December of 2022, the developer of the TALUS La Quinta luxury resort project announced a retooling of the development due to rising labor, materials, and interest rate costs, allowing the development to remain economically viable. The delays will mean an anticipated opening for Fall 2023 and portions of the resort will now be pushed back to early 2024. The City received funding from Quimby fees; pursuant to the State law, these funds are to be used to acquire new parkland or fund capital improvements at existing recreational and park facilities. As a result, in October 2022, the City of La Quinta, in partnership with the Action Park Alliance, opened the La Quinta X Park, a skatepark offering a fun, safe, and accessible skateboard and BMX facility for the community to enjoy. The City of La Quinta is located in the central portion of the Coachella Valley within the southern region of Riverside County. Although the region can be described as rural, La Quinta constitutes an urbanized area that includes a range of residential, commercial, public facilities and open space land uses. Residential development in the City of La Quinta consists primarily of low -density and resort residential development with scattered medium and high -density development occurring in certain areas of the City. Residential lands take up to 31.7% of the land in the city. Commercial land uses exist across the City and account for approximately 4.4% of the designated use. Commercial land uses generally occur at the intersection of two major travel corridors. Corridors include Highway 111, which runs east -west through the center of the City, is a dense commercial corridor, and the Village Commercial area, which is located north of the Cove residential neighborhood. Commercial land use designation serves to provide retail services in conjunction with major tourist attractions such as golf, dining, and resort facilities. The City's open space land use designation largely consists of golf course development in the urban core and land use preservation in the surrounding hillsides. The City has integrated public and private open space area, including parks and recreational facilities. Recreational open spaces include golf courses, multiple parks, open space associated with the Whitewater River and the La Quinta Channel, and recreational trails and opportunities associated with the Santa Rosa and San Jacinto Mountains. Public facilities such as schools, libraries, fire and police stations are characterized as major community facilities and are located throughout the City of La Quinta. The economic development driven by expanding the hotel resort industry in La Quinta can both enhance the city's prosperity and increase its vulnerability in several ways. While the influx of tourists and investment can stimulate job creation, boost local businesses, and increase tax revenue, it also amplifies the city's reliance on a single industry. This concentration heightens vulnerability to economic downturns, shifts in consumer preferences, and external shocks such as natural disasters or global pandemics, which can devastate the tourism sector and ripple through the broader economy. Additionally, the 12 LOCAL HAZARD MITIGATION PLAN 12/21/2023 expansion of hotel resorts may strain resources and infrastructure, exacerbating issues like water scarcity, traffic congestion, and strain on emergency services. Moreover, a heavy reliance on tourism can create disparities in employment opportunities and exacerbate socioeconomic inequalities within the community. Thus, while economic development through the hotel resort industry presents opportunities for growth, it also necessitates careful planning, diversification strategies, and resilience -building efforts to mitigate vulnerability and promote sustainable development in La Quinta. 13 LOCAL HAZARD MITIGATION PLAN 12/21/2023 ■ ir Figure 1.6.2 City of La Quinta Land Use and Development Trends There are a total of 22,855.5 acres of land within the City's limits. The single largest land mass in the city is designated Open Space, which encompasses 53.3% of the total land area within the city, or 12,192.5 acres of Natural and Recreational Open Space. Residential lands take up 31.7% (7,233.7 acres) of the land in the city, and Commercial lands represent 4.4% (1,00S.1 acres) of City lands. 26.9% of residential lands are vacant, while 33.4% of commercial lands are vacant. Approximately 56.4% of lands designated for Major Community Facilities are currently developed (252.7 acres), and 193.8 acres remain available for development. Table 11-3.

Communities may also consider additional hazards for their plans. The HMPC reviewed an extensive list of hazards and excluded those that do not threaten the city of La Quinta. Table 4-1 lists the hazards considered and explains the reasoning for inclusion/exclusion. The Steering Committee considered the full range of natural hazards that could affect the planning area and then listed hazards that present the greatest concern. The process 21 LOCAL HAZARD MITIGATION PLAN 12/21/2023 incorporated a review of state and local hazard planning documents as well as information on the frequency of, magnitude of, and costs associated with hazards that have struck the planning area or could do so. Anecdotal information regarding natural hazards and the perceived vulnerability of the planning area's assets to them was also used. Based on the review, this plan addresses the following hazards of concern (the order of listing does not indicate the hazards' relative severity): • Drought • Earthquake • Flood • Extreme Heat Hazard Screening and Prioritization Following the identification of hazards, the Planning Team went through a process to prioritize (screen) the hazards to determine which hazards created the most significant concern in the community. The Planning Team utilized a ranking implemented during this update to the City of La Quinta LHMP. This process consists of generating a qualitative scale, Very High, High, Medium, or Low rating for 1) Probability and 2) Severity from each hazard. As part of this process, the following criteria (definitions) were applied: Geographic Extent • Extreme: 50-100 percent of the planning area • Extensive: 25-50 percent of the Planning area • Significant: 10-25 percent of the planning area • Limited: less than 10 percent of the planning area Probability • Very Likely: Near 100% chance of it happening. There have been Historic Occurrences of the Hazard in the community or region, and experts concluded it is highly likely that the hazard will occur in the community. Citizens feel that there is a likelihood of occurrence. • Likely: Between 10 and 100 percent chance of happening in the next year. There may or may not have been historical occurrences of the hazard in the community or region, but experts concluded that it is likely that the hazard will occur in the community. Citizens feel that there is a likelihood of occurrence. • Occasional: Between 1 and 10 percent chance of happening within the next year or has a recurrence interval of 11 to 100 years. There may or may not have been a historical occurrence of the hazard in the community or region, but experts concluded that it is possible that the hazard could occur in the community. Citizens may feel that there is a likelihood of occurrence. • Unlikely: Less than 1 percent chance of happening or has a recurrence interval of greater than every 100 years. There have been no historic occurrences of the hazard 22 LOCAL HAZARD MITIGATION PLAN 12/21/2023 in the community or region and both experts and citizens agree that it is highly unlikely that the hazard will occur in the community. Severity • Catastrophic: Both experts and citizens have concluded that the consequences will be significant in terms of building damage and loss of life. More than 50 percent of Property severely damaged, shutdown of facilities for more than 30 days; and/or multiple deaths. • Critical: Consequences are thought to be significant in terms of building damage and loss of life. 25-50 percent of property severely damaged; shutdown of facilities for at least two weeks; and/or injuries/illnesses result in permanent disability. • Limited, but not insignificant: Consequences are thought to be modest in terms of building damage and loss of life, limited either in geographic extent or magnitude. 10- 25 percent of property severely damaged; shutdown of facilities for more than a week; and/or injuries/illnesses treatable do not result in permanent damage. • Negligible: Consequences are thought to be minimal in terms of building damage and loss of life, limited either in geographic extent or magnitude. Less than 10 percent of the property Severely damaged, shutdown of facilities and services for less than 24 hours; and/or injuries/illnesses treatable with first aid. Risk • High: Widespread potential impact • Medium: Moderate potential impact • Low: minimal potential impact Figure 3.4.1 - Critical Facility Replacement Value for City of La Quinta Hazard Geographic Probability of Future Occurrence Magnitude/ Severity Risk Drought Extreme Occasional Critical Low Earthquake Extreme Very Likely Catastrophic High Flood Significant Likely Critical High Extreme Heat Extreme Likely Critical High 1. Drought The city of La Quinta faces moderate drought risk, stemming from its arid climate and reliance on limited water resources. With its semi -desert environment and high temperatures, the region is particularly vulnerable to water scarcity, exacerbated by increasing population growth and agricultural demands. The historic depletion of 23 LOCAL HAZARD MITIGATION PLAN 12/21/2023 groundwater reserves, coupled with erratic precipitation patterns and the looming threat of climate change, further compounds the risk. Drought conditions not only impact local agriculture, a vital economic sector, but also strain water supplies for residents, businesses, and ecosystems alike. Moreover, the valley's dependence on imported water sources, such as the Colorado River, underscores the need for sustainable water management practices and proactive drought mitigation efforts. Addressing the Coachella Valley's drought risk requires a multifaceted approach, encompassing water conservation measures, innovative technologies, community engagement, and long-term planning to safeguard against the adverse impacts of water scarcity and ensure the resilience of the region's economy and environment. Likelihood of occurrence: Likely: Between 10 and 100 percent chance of happening in the next year. Figure 3.4.2 La Quinta Drought Hazard Map Map released: Thurs.

The city has also participated in the California Great Shake -Out exercises annually. The city web pages include information on upcoming trainings, sand bag distribution sites and preparedness information. Community outreach activities also provide valuable information to residents at City -sponsored events, homeowner's association presentations, and programming with the school district. Preparedness Training - The City of La Quinta has trained all City employees in disaster preparedness including the California SEMS (Standardized Emergency Management System), the NIMS (National Incident Management System), and the ICS (Incident Management System) as required by the Federal Emergency Management System. La Quinta has also trained all Emergency Operations Center (EOC) staff in EOC Operations and being a Disaster Service Worker under California Law. The city has hosted ICS-300, ICS-400 and the EOC Rapid Assessment Workshop which has improved coordination among City staff as well as our community partners who were in attendance. La Quinta has also hosted Community Emergency Response Team (CERT) training annually as well as supported the local RACES (Radio Amateur Civil Emergency Services) team members. Warning & Communication - The City of La Quinta has updated and maintained its communications equipment to allow for direct communication with Riverside County as well as interoperability among all of the city departments. With the help of RACES, the city has participated in monthly County -wide tests of the Disaster Network. La Quinta also has 50 LOCAL HAZARD MITIGATION PLAN 12/21/2023 access to Riverside County's Early Warning Notification System through the Fire Department, Police Department, and the Emergency Services Coordinator, allowing it to utilize a reverse 911 public warning system and send out notifications and public warning information. La Quinta also utilizes their own system, Nixle, for internal communications with City staff, City representatives, and CERT volunteers, allowing it to disseminate emergency information for safety and EOC activation purposes. Emergency Operations Center (EOC) - The City of La Quinta funded and built a state-of- the-art Emergency Operations Center in 2008 that includes over 6,000 square feet of space and houses a Radio Communications Center, an Operations Room, offices for Management, Operations, Logistics, Planning, Finance and Administration, and the Public Information Officer. The EOC also has bathrooms, a staff kitchen, equipment and supplies storage and support areas for making post -emergency decisions for the community. FEMA FIRM Maps were updated on August 28, 2008 removing the EOC and City Hall from flood hazard area. Since the COVID-19 pandemic, the importance of having a virtual EOC was immediately recognized. The city will begin to use the WebEOC platform to train staff on how to run a virtual EOC operation in 2023. Bear Creek System - The Coachella Valley Water District (CVWD) in 1985 designed and constructed the Flood Improvements Project to the La Quinta Cove which provides at least 100-year-storm flood protection to the Cove area. This system intercepts and detains runoff originating from approximately 12.7 square miles of foothill drainage located southwest and west of the Cove. The system was also designed to handle runoff from 1.7 square miles of drainage area located due south of La Quinta and diverted to the Bear Creek System by the Upper Bear Creek Training Dike. The Bear Creek System consists of the following features: Upper Bear Creek Training Dike Upper Bear Creek Detention Basin Bear Creek Channel Debris/Retention Basins The system conveys storm runoff past the western limits of La Quinta to the Oleander Reservoir located northwest of the intersection of Eisenhower Drive and Calle Tampico as part of the Dunes Golf Course at the La Quinta Hotel and Spa. The upper Bear Creek Training Dike diverts storm water runoff from 1.7 square miles of drainage area south of Calle Tecate into the Upper Bear Creek Detention Basin. The Upper Bear Creek Detention Basin is located at the mouth of the Bear Creek southwest of La Quinta and contains a total of 752 acre feet of storage for temporary detention of storm runoff and detention of debris. This basin is about 700 feet wide by 1,350 feet long which discharges via a weir structure into the Bear Creek Channel. The Bear Creek Channel is a 2.5 mile long, soil cement lined, trapezoidal channel which runs between the Upper Bear Creek Detention Basin to the north between the west side of the La Quinta Cove and the easterly toe of slope of the adjacent hillsides and then discharges into the Oleander Reservoir. Along the way four side drainage 51 LOCAL HAZARD MITIGATION PLAN 12/21/2023 inlets pick up storm water from the mountainside to the immediate west of the Channel. The Oleander Reservoir can safely carry the runoff from a 150-year event from the Bear Creek Channel. The reservoir discharges to the east into the La Quinta Evacuation Channel which can carry up to a 200-year event, and that discharges into the Whitewater Channel which has an approximate 500-year storm capacity. East La Quinta System - This system intercepts runoff originating from 2.5 square miles of drainage area in the foothills east and southeast of Avenida Bermudas, from the area south of Calle Tecate to the Upper Bear Creek Training Dike, and from south of Calle Tecate east of Avenida Bermudas north to Calle Durango. The East La Quinta System consists of the following: Upper Training Dike Calle Tecate Detention Basin East La Quinta Channel Avenida Bermudas Detention Basin 60-inch Diameter Buried Storm Water Conduit The Upper Training Dike diverts storm water flows from .37 square miles of drainage area east of the dike into the Calle Tecate Detention Basin located just south of the intersection of Calle Tecate and Avenida Bermudas. This basin has a capacity of 200 acre feet. This basin outlets via a 36-inch diameter pipe into the East La Quinta Channel which also intercepts .14 square miles of runoff from the foothills east of Avenida Bermudas. Both the Calle Tecate Detention Basin and the East La Quinta Channel receive surface water from adjacent City streets. The East La Quinta Channel flows north along the toe of the foothills to the Avenida Bermudas Detention Basin. This Detention Basin connects to the basin system constructed as part of the Heritage Club development which is now called The Traditions Golf Club. These basins were designed for a minimum 100-year event capacity. The basins then connect to a 60-inch diameter buried storm water conduit that continues underground to the north where it discharges to the Evacuation Channel which then flows to the Whitewater Channel. The Planning Committee for the City of La Quinta identified and prioritized the following mitigation actions based on the risk assessment. Background information and information on how each action will be implemented and administered, such as ideas for implementation, responsible office, partners, potential funding, estimated cost, and schedule are included. 6.5 MITIGATION PROJECTS The Focused Area Drainage Study of March 2016 evaluated select areas of the City and identified the scope and approximate cost of drainage system improvements to augment the City's existing flood control and drainage systems to increase capacity to accommodate up to a 500-year storm event. 52 LOCAL HAZARD MITIGATION PLAN 12/21/2023 Citywide Drainage Enhancements: The Citywide Drainage Enhancements have already begun with the Washington Street Enhanced Drainage Improvements and the Eisenhower Drive Enhanced Drainage Improvements. Upon completion of these two projects, focus and funding will be shifted to the La Quinta Village Area along Calle Tampico. This project is ongoing, but the likeliest streets to flood have already been worked on and have proven to lessen flash floods in comparison to how the street was before. (Eisenhower Dr. and Calle Tampico are complete). Funding: Local Funds - General Fund 6.6 FUTURE MITIGATION PROJECTS Avenue 50 Bridge Spanning the Evacuation Channel The proposed improvement will replace the at -grade crossing on Avenue 50 at the La Quinta Evacuation Channel with a new four lane all weather bridge. The improvements will include a 200-foot three -span bridge, raising the roadway approach grades, concrete slope protection, relocation of utilities, and the acquisition of right-of-way. As of fiscal year 2022/2023, this project has been postponed until The Highway Bridge Program Funding in the Federal Transportation Improvement/Regional Transportation Plan is released.

Embracing an all -hazard approach, the city promotes information sharing among its departments to enhance overall planning endeavors. While previous team members have advocated for LHMP integration, there lacks a formalized process to achieve comprehensive integration. A thorough examination of the previous LHMP revealed a notable absence of integration of identified projects or mitigation actions into key city plans or planning initiatives. Thus, the city is determined to establish robust mechanisms to seamlessly incorporate LHMP information into its various planning efforts, ensuring better preparedness and resilience against evolving hazards. As a result, the City of La Quinta will be 54 LOCAL HAZARD MITIGATION PLAN 12/21/2023 incorporating the 2023 Local Hazard Mitigation Plan into: • The City of La Quinta General Plan • The City of La Quinta Emergency Operation Plan • The City of La Quinta Capital Improvement Project Plans • Tittle 8 Building and Construction • Tittle 9 Zoning This integration of the LHMP into the City of La Quinta General Plan also allows the city to comply with AB 2140 requirements. SECTION 8.0 - PLAN IMPLEMENTATION AND MAINTENANCE PROCESS The Plan's effectiveness depends on the successful implementation of the mitigation actions. Implementation includes integrating mitigation actions into existing City plans, policies, programs, and other implementation mechanisms. The mitigation actions in this Plan are intended to reduce the damage from hazard events, help the city secure funding, and provide a framework for hazard mitigation activities. These priorities will guide the implementation of these actions through new or existing city mechanisms as resources are available. The City of La Quinta regularly updates the City's Municipal Code to keep current with new Federal and State regulations, novel circumstances, and potential hazards that are discovered in the normal course of City activities or by means of training and exercise. City staff bring draft ordinances to any relevant Commissions, then to city Council for consideration and public input. Council and public -approved changes and ordinances that have passed the necessary number of readings are codified into the City's Municipal Code. The LHMP has been incorporated into the following: • General Plan Safety Element (01/25/2022) • Emergency Operations Plan (05/03/2010) • 2016 California Building Code (Eff. 01/01/2017 to 12/31/2019) • 2016 California Residential Code (Eff. 01/01/2017 to 12/31/2019) • 2016 California Mechanical Code (Eff. 01/01/2017 to 12/31/2019) • 2016 California Plumbing Code (Eff. 01/01/2017 to 12/31/2019) • 2016 California Electrical Code (Eff. 01/01/2017 to 12/31/2019) • 2016 California Energy Code (Eff. 01/01/2017 to 12/31/2019) • 2016 California Green Building Standards Code (Eff. 01/01/2017 to 12/31/2019) • 2016 California Existing Building Code (Eff. 01/01/2017 to 12/31/2019) • 2016 California Historical Building Code (Eff. 01/01/2017 to 12/31/2019) • 2016 California Fire Code (Eff. 01/01/2017 to 12/31/2019) The City of La Quinta will monitor and evaluate our LHMP on a yearly basis over the next 5 years. We will review the LHMP and assess: 55 LOCAL HAZARD MITIGATION PLAN 12/21/2023 • The goals and objectives and address current and expected conditions. • If the nature, magnitude, and/or type of risks have changed, we will update plan as necessary. • Current resources for implementing the plan and explore new resources. • Implementation problems, such as technical, political, legal, or coordination issues with other agencies. • The outcomes to ensure they are in line with the expected result, if not we will modify plan. • Changes in Federal, State, and local ordinances, if laws and regulations have changed, we will make changes to reflect current regulations. • Involve public by posting notices on websites and announcements during public meetings intent to review and update Local Hazard Mitigation Plan allowing for public comment and input. If we discover changes have occurred during the evaluation, we will update the LHMP Revision Page, and notify Riverside County EMD to update our Annex. The Riverside County Emergency Management Department will coordinate the monitoring, evaluation and update of the LHMP. SECTION 9.0 - CONTINUED PUBLIC INVOLVEMENT The City of La Quinta will encourage public involvement and comments. Public meetings are displayed on the City's webpage and posted locally at City Hall, the Post Office, and the grocery market. The purpose is to inform the public and allow an opportunity for comment. The City of La Quinta identified stakeholder groups in the community with wide-ranging interests and facilitated stakeholder group meetings to solicit input and ideas about mitigation strategies. We will continue to include them in the process to review and provide public comment on an annual basis through Public Hearings at the Planning Commission, Public Safety Commission and City Council meetings. Additionally, the City of La Quinta will maintain public involvement opportunity notifications on the City of La Quinta's website and through the following other format: • Social Media (Facebook and Twitter): The City of La Quinta's residents rely heavily on the internet and social networking sites for information and community - building.
