Service Plan Exhibit K Water Service Plan Specific Plan City of La Quinta 1.1 Introduction & Purpose The Specific Plan establishes the philosophy and guidelines for the development of the property located at the southeast corner of Miles Avenue and Washington Street in the City of La Quinta. The guidelines presented within this document are in accordance with the established City's Zoning Code and General Plan, reflect the quality and design desired at the site and conform to the City's overall goal of preserving, maintaining and enhancing the high quality of life La Quinta residents enjoy. Although the Plan is designed to ensure the quality of the development, it also provides a degree of flexibility to allow future development to respond to the changes in society and the economic marketplace of the region which will inevitably occur over the build out period. In cases where the zoning and development regulation is nonspecific within the document, the zoning and development regulation is guided by the City of La Quinta Zoning ordinance in effect at the time. 1.2 Enabling Legislation • The authority to prepare, adopt, and implement the Specific Plan is granted to the City of La Quinta by the California Government Code (Title 7, Division 1, Chapter 3, Article 8, Sections 65450 through 65457). • As with General Plans, the Planning Commission must hold a public hearing before it can recommend to the City Council the adoption of a Specific Plan or an amendment thereto. The City Council of La Quinta may adopt a Specific Plan and/or amendment to the Specific Plan by either ordinance or resolution. The Specific Plan is a regulatory document that, once adopted, will amend the Zoning Ordinance, and serve as the Development Code for the Development Site. Upon completion of the Specific Plan adoption process, future development must be consistent with the Specific Plan and amendments thereto. PAGE 1 SPECIFIC PLAN CITY OF LA QUINTA 1.3 The Property Main access to La Quinta is achieved by traveling south on Washington Street from Interstate 10. The approximate 50 -acre subject property is situated at the southeast corner of Miles Avenue and Washington Street, a major entry point to the City. The property is bound by the Coachella Valley Stormwater Channel to the south, the Del Oro subdivision and vacant residential land to the north and the Inco Century single-family subdivision to the east. The vacant desert land is surrounded by uninterrupted views of the Santa Rosa Coral Reef Mountains and the Little San Bernardino Mountain Range. An aerial photo of the property is provided in Exhibit A. 1.4 The Ownership The subject property, consisting of parcel numbers 604-04-12, 604-04-13, 604-04-23 and 604-04-37, is owned by La Quinta Redevelopment Agency. 1.5 Development Vision The City has envisioned a development that would welcome incoming tourists, residents and passer-bys into the community of La Quinta. The site serves as the "front door" to the community and should be considered a location that defines the character of La Quinta. The landscape, architecture, design and integrity should reflect the pride and history of the community and shall be developed with the utmost quality and creativity. PAGE 2 SPECIFIC PLAN CITY OF LA QUINTA The design guidelines and development plan described in this document sets the stage for the development of the following: • A commercial component consisting of resort style hotels, timeshares, condominium -hotels, up -scale restaurants serving the residents of the community and the guests of the resorts and commercial/retail uses. • A residential component consisting of townhomes, single-family residential homes and a neighborhood park. 2.1 Land Use 2.1.1 Land Use Plan The property is currently divided into two land use categories: Park and High Density Residential as depicted in the figure below: Approval of the Specific Plan would change the current land use to contain approximately 22 acres of Tourist Commercial, 20 acres of Medium Density Residential allowing between 4 and 8 dwelling units per acre, 5 acres of Park and a 1 acre well site. The figure below presents the revised land use for the development: PAGE 3 2.1.2 Zoning and Development Standards SPECIFIC PLAN CITY OF LA QUINTA til Lif The following section establishes the zoning and development standards for the three land use areas within the development.

A. Purpose. To provide for the development and preservation of a neighborhood park. B. Permitted Uses. The following uses are permitted in the PR Zoning District with approval of this Specific Plan, pursuant to the procedures set forth in Section 9.120.020 of the La Quinta Zoning Ordinance and as set forth herein. 1. Open Space 2. Public parks and passive recreation facilities 3. Playfields, unlighted 4. Restrooms 5. Park Site Concept The Site Concept is presented in Exhibit B of this document. As the gateway to the City of La Quinta, the architectural and landscape design of the site will be developed to enhance the qualities of the City. The intersection corner of Miles and Washington, due to its prominent location, PAGE 7 SPECIFIC PLAN CITY OF LA QUINTA will be monumentally landscaped to create a sense of arrival to the site and landscaping along the streets will respond to the existing boulevard character. A landscape buffer will be designed to mitigate traffic noise and will be oriented to preserve views of distant mountains. Sloping berms at a maximum height of 4' from curb height will be planted in layers to restrict the views of parking areas from surrounding streets. Within the site, Seeley Street will be lined by entrances in the residential component and by storefronts in the commercial component. The broad, pedestrian -scaled character of the street will run through the site, and will feed into plaza turnarounds at the resort and restaurants. In the residential area, broadened sidewalks behind parkway planting will be considered an extension of and provide access to the neighborhood park. The pedestrian -accessible park will serve as green space for the residents. 2.3 Architectural Character The buildings constructed on the site should maintain a consistent theme carried out by quality materials and imaginative design consistent with the existing character of La Quinta. Building design shall be unique to the site in that the configuration should take advantage of and preserve surrounding vistas. Additional reference material is provided in Exhibit C of this document. Other salient characteristics of the architectural character are: • The use of simple plaster masses with deep punched openings, arched entryways, and shading elements. • Horizontal and vertical building offsets to create articulated breaks and visual relief. • Wood detailing, tile work, and vivid colors at key places along broad plaster masses. Building integration architecture appears landscape. with indigenous landscaping, such that the as an extension and outgrowth of the • Strategic orientation and configuration of buildings and shading elements to passively heat and cool spaces. • False roofs are prohibited. Flat roofs may be used in combination with other roof forms. The simple yet strong architectural vocabulary for the development should rely on strategically placed key details and the careful selection of PAGE 8 SPECIFIC PLAN CITY OF LA QUINTA landscape materials. The details employed include arcades, balconies deeply recessed openings, low walls, wood detailing and awnings. 2.3.1 Resort Uses • The following architectural elements should be incorporated in order to increase building articulation and reduce the scale of the three-story hotels: o Elements such as awnings, balconies roof overhangs, or trellises that protrude from building elevations. o Varying roof plate heights that create a layered or staggered roofline. o Elements such as arcades or balconies that "step" in plan and elevation, creating shadow and depth. • Entries should be articulated with larger openings in the facade, richer building materials and colors, and arcades or portals. • Entry plazas and courtyards should include shading elements such as trellises and landscaping. 2.3.2 Residential Uses The design of the residential component shall incorporate elements that respond to the climate of La Quinta. Such design features include patios, balconies, courtyards, arcades, plazas and paseos. Extended roof overhangs shall be incorporated into building design to provide additional shade. Overall design of the residential component shall incorporate the following guidelines: • Architectural design shall be unique in character, but consistent with surrounding area. • Orientation of structures should consider the climate of the area. • Housing edges should maximize view potential and access to natural open areas. • Porches and balconies should be designed to promote social interaction among community residents and should be an integral component of the buildings architectural style. PAGE 9 SPECIFIC PLAN CITY OF LA QUINTA • Mechanical elements of the building shall be screened from view by walls, fences or landscaping. • Varying house configurations is encouraged to promote variety in the street scene. • Streets shall be curvilinear. 2.4 Landscape Overall development identity and character is defined and enhanced by the continuity of landscape materials along publicly visible areas. Individual parcel identity can be established through variations in landscaping at major entry points, along smaller streets within the development, and within individual parcel open space areas. Exhibits D 1- 6 provide general guidance for the development of a final landscape plan for the development. 2.4.1 Landscape Concept The landscape architectural theme for the development is to create an identifiable "signature" landscape character for the development. Landscaping is subject to the City of La Quinta water efficient landscape ordinance. Additional guidelines within this document are intended to achieve the following goals: • Create a signature landscape theme defining the character of La Quinta • Enhance major views by landscape treatment • Utilize drought tolerant landscape • Create hierarchy of theme signage from monumental entrance to individual parcel identity. • Create focal points • Utilize tree massing to screen the rear and sides of outdoor industrial uses • Strategically clusters dense landscaping to serve as wind barriers. The landscape concept shall consist of three zones to maximize water efficiency as well as to keep maintenance at a minimum. The three zones are as follows: • Water Efficient `Drip Zone' — These areas will receive the least amount of use (e.g., median islands, parking islands, etc.). PAGE 10 SPECIFIC PLAN CITY OF LA QUINTA Plantings in this zone will consist of drought tolerant low shrubs, ground covers and desert trees. Crushed 'fines' rock and large boulders can be used in addition to ground covers. The irrigation system will be drip. (See Exhibit D-1) • Transitional Landscape Zone — These areas will bridge the gap between zone 1 and zone 3 and generally be seen along the street frontages. Medium shrubs, canopy trees and a limited amount of turf will be used. Turf areas should be irrigated with short flat spray heads that have short radii to reduce the amount of over spray and resulting damage to adjacent hardscape. (See Exhibit D-1) • Building Entry Zone — These areas will be located at building entries, courtyards or other recreational facilities that will receive maximum use. Ground covers, shrubs and trees with more abundant foliage will be used to create a cooler, quieter environment for the users of these spaces. (See Exhibit D-1) 2.4.2 Streetscape Concept The streetscape concept is the primary landscape influence for the development and is intended to unify the development. The streetscape components consist of meandering sidewalks, identifying street tree patterns, and a bermed edge accented with shrubs, ground covers and rock. Turf areas will be located at intersections where ample space is provided. Shrubs will be used as a screen where necessary. Root barriers for trees shall be used for any tree that is located closer than 6' from adjacent hardscape. 2.4.2.1 Washington Street and Miles Avenue Tree Design The dominant tree along Miles Avenue shall be Prosopis Alba (Thornless Mesquite) planted in informal clusters to follow the meandering walk approximately 50 ft. intervals. The trees should be accented by clusters of Washingtonia filifera (California fan palm). Date palms should be incorporated at significant development entry drives. Washingtonia robusta (Mexican fan palm) can be used outside right-of-ways to accentuate buildings or other site enhancements. Landscape lighting may occur at specimen plants or to accent clusters. 2.4.2.2 Seeley_ Drive Tree Design Seeley Drive should be planted with Tipuana Tips (Tipu Tree) to lineate the road. Washington filifera (California fan palm) shall be used to accent major parcel entries. Significant specimen plants will be accented with PAGE 11 SPECIFIC PLAN CITY OF LA QUINTA uplighting. To supplement this pattern, other species of trees can be used on site. Please refer to the plant palette (See Exhibit E). 2.4.2.3 Development Entries at Washington Street and Miles Avenue Development entries at Washington Street and Miles Avenue shall continue the Date Palm theme from the development entries as mentioned above. Date palms shall be spaced formally at 25' intervals along the center median. Along either side of the street, Date Palms will occur at 25' intervals and be placed to follow the contour of the meandering sidewalk. (See Exhibit D-2, 3). 2.4.3 Parking Areas Parking area landscaping shall be designed to accomplish the following: • Provide shading • Serve as a visual barrier from Miles Avenue, Washington Street and Seeley Drive. Landscaped islands shall be provided at the ends of stall rows to break up parking areas by creating a series of smaller parking pockets. Parking pockets shall be distributed at a minimum of one per 10 parking stalls and should provide a minimum of 10' landscaped width to allow planting and mounding. The landscaped islands shall be a minimum of 9' wide providing a minimum of 6' wide landscape space. Islands shall contain large canopy trees to provide shade. Parking lots shall have 24" box trees (2"-3" Caliper) whose placement shall be such that the mature tree spread will shade fifty percent (50%) of the parking stall area with tree canopies within 15 years. Along Miles Avenue and Washington Street, parking must be screened with a block wall and/or berm (3:1 slope maximum, height of 4' from curb height) with adequate landscaping planted between the property line and the paved parking areas. Shrubs should partially screen cars and aisles, transforming vast parking lots into a series of smaller alcoves. (See Exhibit D-5). 2.4.4 Minimum Landscaping Guidelines These development regulations are meant to meet the City of La Quinta water efficient landscape ordinance and to define an appropriate plant palette that will reinforce the unique identity of the development, yet provide flexibility and diversity in planting design. PAGE 12 SPECIFIC PLAN CITY OF LA QUINTA • A limited selection of plant materials used in simple, significant compositions is encouraged. Planting design should be compatible with and compliment adjacent plantings, reinforcing and enhancing the individual architecture and design of the site. The materials on the Plant Palette (See Exhibit E) have been selected for their contribution to the development theme, their adaptability to climatic and soil conditions and with respect for long term cost effective maintenance. Detailed landscape and irrigation plans are to be prepared by a landscape architect licensed in the State of California for each individual component of the development. The landscape plans are to be submitted to the City for review. All landscape areas are to be served by a permanent automatic underground irrigation system. 2.5 Art in Public Places Fees generated for the development of this site shall be utilized to provide public art in Land Use Area I. In lieu fees will not serve as a substitute for public art. 2.6 Sustainability Guidelines In response to the recent California energy crisis the City is taking a proactive role in development by ensuring that energy efficiency standards will be incorporated into this Specific Plan. An energy efficiency plan shall be submitted to the City for approval and shall include the following aspects: orientation, shading, solar paneling and energy efficient products. 3.1 Circulation The circulation system for the Specific Plan conforms to the requirements of the City of La Quinta General Plan — Circulation element by providing a hierarchy of vehicular traffic -ways with pedestrian -ways segregated within the plan area. A detailed discussion of the technical issues of traffic impact analysis is presented in a site specific report prepared by Urban Crossroads. The following guidelines shall be implemented to provide a hierarchy of travel options to residents and guests within the development: PAGE 13 SPECIFIC PLAN CITY OF LA QUINTA Construct internal roadways that provide a safe route for development ingress and egress to both commercial and residential areas. • Construct bike paths connecting with the system of bike paths outside the development area consistent with the architectural theme and landscape character. • Construct pedestrian meandering walkways connecting commercial, residential areas with surrounding sidewalks. Walkways shall blend with the surrounding landscape character and provide interconnectivity within the development. 3.1.1 Off -Site Improvements The development shall contribute towards a citywide roadway and traffic signal improvement program as a result of infrastructure development fees for the City of La Quinta. These fees shall be paid at the building permit stage of development. 3.1.2 On -Site Improvements • Construct Seeley Drive from Washington Street to Miles Avenue at its ultimate width as a local street in conjunction with development. • Sight distance at the development entrance should be reviewed with respect to standard Caltrans/City of La Quinta sight distance standards at the time of preparation of final grading, landscape and street improvement plans. • Traffic signaling/striping at Miles Avenue and Seeley Drive should be implemented when warranted in conjunction with detailed construction plans for the development site and shall be financed 100% by resort developer. • The Public Works Department shall consider the option to install a left turn pocket for southbound Seeley Drive. 3.2 Grading Plan Exhibit F depicts the Preliminary Grading Plan for the development. The grading plan identifies proposed land uses within the site boundary, preliminary pad locations and elevations, contours, and basin locations. It is intended to convey the potential to develop buildable parcels on the subject property, based on a conceptual site plan. It may also be used as a guide for the development of a rough grading plan. PAGE 14 3.3 SPECIFIC PLAN CITY OF LA QUINTA The existing terrain consists of small, undulating sand dunes. The elevation difference from the high point (intersection of Washington and Miles) to the low point (C.V.W.D. access road along the Coachella Valley Stormwater Channel) is approximately forty-two feet. Landscape setbacks and graded slopes will be required along both Washington Street and Miles Avenue (refer to development standards). The proposed finish grade elevations near the existing single-family residential development are within one to three feet of existing grades. It is anticipated that the site will be rough -graded in one operation, with extensive export operations required. Site Cross Sections are shown in Exhibit G. Street Cross Sections are shown in Exhibit H. 3.2.1 Wind & Erosion Control The Coachella Valley experiences periods of moderate; to high wind conditions. Therefore, wind blown dust and sand are a concern during local grading operations. The South Coast Air Quality Management District and the Environmental Protection Agency have instituted a plan in the Coachella Valley to reduce excess PM 10 (small particle dust). These provisions must be adhered to during grading operations. 3.2.2 SWPPP/NPDES/PM10 The provisions of the National Pollutant Discharge Elimination System (NPDES) apply to construction projects over 5 acres in size. Since the development site is over 40 acres, a Notice of Intent (N.O.I.) and NPDES permit containing a Best Management Practices Plan must be filed/prepared. Furthermore, a Stormwater Pollution Prevention Plan (SWPPP) must also be prepared for the development and submitted to the City of La Quinta. Drainage and Flood Control The Drainage Plan for the site is shown in Exhibit I. The following guidelines shall be used to implement a sufficient drainage and flood control plan. 3.3.1 Temporary Measures The drainage plan proposes to temporarily direct surface runoff via graded swales to two retention basins during the development of the site. The large retention basin in the southeast corner of the site is part of the interim drainage plan. This basin should be utilized until the development of the proposed single-family residential area. Ultimate Drainage facilities PAGE 15 SPECIFIC PLAN CITY OF LA QUINTA sufficient to handle each phase of development must be constructed during the appropriate phase. These facilities would likely consist of combination inlets/drywells connected to a pipe system that outlets through the Coachella Valley Stormwater Channel wall. With the drywells sized appropriately, this type of system eliminates nuisance flow discharges to the channel, provides an emergency overflow through the channel wall and eliminates surface runoff over the channel wall. Due to the phasing of the development, reciprocal drainage agreements may be necessary. 3.3.2 Permanent Measures The large basin in the southeast corner of the site captures the majority of the site runoff. The tributary area for this basin is approximately 39.1 acres. The basin depth is six feet with a storage capacity of 146,000 cubic feet. The basin capacity is adequate for the 100 -year storm. The park basin depth is one foot, with a storage capacity of approximately 60,000 cubic feet. The tributary area for the park basin is 3.3 acres. The park basin storage capacity is also adequate for the 100 -year storm. The proposed park area is also a retention basin and is part of the ultimate storm drain facilities. 3.4 Utilities The infrastructure that will serve the development is described below and is designed to provide a coordinated system of infrastructure and public services to adequately serve the plan area at full build out. The infrastructure and utilities plan identifies standards relative to land use for the plan area and establishes the infrastructure and public service policies. 3.4.1 Sewer Plan The development is located within the jurisdiction of the Coachella Valley Water District (CVWD) for sewer service. As shown in Exhibit J, an existing 18 -inch sewer main is located along the CVWD channel access road, to the south of the development. Preliminary discussions with CVWD have indicated that two connections to this existing District facility are appropriate. One sewer service will connect to an existing manhole near the southwest corner of the development (near the intersection of Washington Street and the Coachella Valley Stormwater Channel) and extend northward along Washington Street to future Seeley Drive. This line will extend up Seeley and provide service for the proposed restaurant, commercial, hotel, and townhouse developments. The second sewer service will connect to an existing manhole near the southeast corner of PAGE 16 SPECIFIC PLAN CITY OF LA QUINTA the development. This service will extend on site and be used for future single-family residential development. 3.4.2 Water Plan The development is located within the jurisdiction of the Coachella Valley Water District for water service. As shown in Exhibit K, existing 18 -inch water stubs are located at both ends of future Seeley Drive. Preliminary discussions with CVWD have indicated that the developer would be required to complete this 18 -inch loop. On-site domestic, irrigation, and fire flow water would be provided from the proposed 18 -inch pipe. 3.4.3 Electrical Plan Electric service is provided to the site by the Imperial Irrigation District (IID). A preliminary discussion with IID has indicated that electrical facilities are located on the south side of Miles Avenue and the east side of Washington Street. Further discussion with IID will be necessary to identify the exact location of these facilities. Service to the development is assumed to be routine. 3.4.4 Other Utilities 3.4.4.1 Natural Gas Natural gas service is provided to the site by the Southern California Gas Company. Based on "as -built" plans, an existing gas main has been identified in Washington Street, adjacent to the site. Further discussion with the Gas Company and a field investigation are recommended to determine the exact location of the pipe. Service to the development is assumed to be routine. However, some cutting and removal/reconstruction of pavement and curb will be required. 3.4.4.2 Telephone Telephone service will be provided to the development by Verizon. Based on "as -built" plans, existing telephone facilities have been identified in both Washington Street and Miles Avenue. Further discussion with Verizon will be necessary to accurately locate these facilities and determine the preferred connection points. Service to the development is assumed to be routine. It is likely that some cutting and removal/reconstruction of pavement and curb will be required. 3.4.4.3 Cable Television Cable Television service will be provided to the site by Time Warner. Based on correspondence with the cable company, empty conduits exist PAGE 17 SPECIFIC PLAN CITY OF LA QUINTA along the south side of Miles Avenue and the east side of Washington Street. The exact location of these conduits is not known. Further discussion with the cable company will be necessary to determine if extension of existing cable lines to serve the development is feasible. 3.5 Phasing The following diagram illustrates the phasing schedule for the development. Hotel and commercial uses shall be constructed within the first phase of development. The second phase shall consist of residential. The developer shall determine phases within each of these components. �1, J i �— EwsnN� AESgENTIA.Nilk.Y II �F- ~�F r PAGE 18 SPECIFIC PLAN CITY OF LA QUINTA Land Use Element Policy 2-1.1.6: "The density standard for this category shall range from 4-8 DU/AC ("dwelling units per acre"). The maximum density shall be 8 DU/AC. The general residential product type shall be characterized by one to two-story, single-family detached homes on medium and small lots and/or one to two-story, single-family attached units in projects with open space, subject to conditions for varying residential use guidelines as specified in Policy 2- 1.1.9. Appropriate locations of MDR uses include the Cove Area, near transportation arteries and in planned communities." • The Specific Plan proposes a density of 4 - 8 DU/AC for residential land uses. Policy 2-6.2.1: "The Tourist Commercial (TC) category shall provide for a narrow range of specialized uses oriented to tourist and resort activity. The TC category includes destination resort hotels, convention -oriented hotels/motels, eating and drinking establishments, accessory retail and personal service shops, and recreational uses such as golf, tennis, and equestrian facilities. The size of these facilities will vary with many of a region wide interest." • The proposed Specific Plan would attract businesses suitable for the TC category. Policy 2-6.2.3: "The development of hotels and related tourist -oriented uses is highly desirable to provide a future revenue base for the City." • The Specific Plan proposes to construct 2 hotels and commercial/retail uses that compliment the hotels. Policy 2-6.2.4: "The City -should establish standards to guide quality tourist -oriented facilities/developments." • The Specific Plan serves as the standards development. the development of high to guide tourist -oriented PAGE 19 SPECIFIC PLAN CITY OF LA QUINTA Policy 2-6.4.6: "The Park Facilities (P) category shall provide for the designation and preservation of improved public parks and recreational facilities in the City. For the purposes of this General Plan, a park facility is defined as a developed parcel of land which includes a variety of active (i.e., baseball/softball diamonds, football/soccer fields, court sports, etc.) and/or passive (i.e., seating areas, walking paths, viewing/interpretive areas, etc.) recreational facilities. • The Specific Plan proposes the development of passive recreation within the project boundaries. Policy 2-6.4.7.- "The -6.4.7: "The designation, location and standards for the development of neighborhood, community and regional park facilities identified in the Land Use Policy Diagram shall be consistent with the Park and Recreation Element of this General Plan." • The standards for park development are consistent with those stated in the General Plan.
