Section §65450.1 of the Code states that "The legislative body or planning agency may designate areas within a city or county for which the development of a Specific Plan will be necessary or convenient to the implementation of the general plan." A Specific Plan is a tool for the systematic implementation of the City's General Plan within a defined geographic area. It allows for the development of unique and special characteristics within the defined area to be recognized and specifically addressed in the planning and development process. The Sand Harbor Specific Plan establishes land use and development guidelines for the area and criteria for development of the property providing consistency with applicable state laws and local ordinances, conformity to the adopted General Plan, compatibility with adjacent development, and availability of public services and facilities adequate to serve the development. Where there may be a conflict between this Specific Plan and the Conditions of Approval for this Plan, the Conditions shall prevail. 1.2 Purpose The purpose of the Sand Harbor Specific Plan is to assure creation of an attractive, feasible, and marketable vision for the area's future development. The study process has resulted in a plan that affords the highest and best use of the project that builds upon the existing strengths of the area incorporating the desired elements currently existing in the area. The Sand Harbor Specific Plan insures a quality development consistent with the goals, objectives, and policies of the City and the goals of the developer of the project in implementation of the General Plan. This Specific Plan provides an overview and analysis of the proposed project for the property located at the northwest corner of Fred Waring Drive and Jefferson Street currently within the jurisdiction of the County of Riverside, pending annexation to the City of La Quinta. The subject site in this report shall be referred to as "Sand Harbor." 1.3 Summary of Preparation Process Preparation of the Specific Plan for Sand Harbor was conducted in a manner that studied the effects of the land in many different aspects. Information was compiled with the assistance of sources such as the Desert Sands Unified School District, the City of La Quinta, Riverside County Fire Department, various consultant agencies, Riverside County, and the La Quinta Chamber of Commerce. Studies of the site were conducted by RKJK and Associates for Traffic, Archaeological Associates for Archaeological Assessment, Douglas Eilar for Noise, Southland Geotechnical for Geological, and Warner Engineering for Hydrology. In terms of establishing permitted uses and setting forth particular design guidelines and development standards that are unique to the developer and the development intended by this Specific Plan, the City's Zoning Code shall apply in instances that this Specific Plan does not address. 1.4 Location and Acreage The proposed Sand Harbor project lies on a 118 acre site located at the northwest corner of Fred Waring Drive and Jefferson Street. This site is located within Riverside County immediately adjacent to the City of La Quinta City limits. Total buildout of the project will result in the construction of 379 residential dwelling units with related private and public improvements and amenities. Both the existing Riverside County zoning and general plan designation allow for this type of residential development proposed on this site. Upon completion of the subsequent annexation to the City of La Quinta, the community of Sand Harbor will conform the City of La Quinta General Plan and Zoning development standards. Exhibit "A" shows an aerial view of the land designated for the development of Sand Harbor. 1.5 Consistency with the General Plan 1.5.1 Circulation Element The Sand Harbor development provides for a balanced circulation system that will provide a diversity of travel opportunities by incorporating a design that accommodates both pedestrian and bicycle access to the site, across the site frontage, and on the site as part of the community's efforts to establish non - automotive transportation as a viable alternative to driving. The Circulation Element of the General Plan identifies Fred Waring Drive as a major arterial currently used as a pass-through between communities located to the east and west of La Quinta. Currently, the Fred Waring Drive intersection at Jefferson Street is- controlled by stop signs.

The Sand Harbor development shall implement the policies set forth for circulation as a result of the Traffic Impact Analysis which projects to generate a total of approximately 3,627 trip -ends per day with 284 vehicles per hour during the AM peak hour and 382 vehicles per hour during the PM peak hour. 1.5.2 Land Use Element Development policies for La Quinta are characterized through the development that conforms to building intensities as shown on the Land Use Policy Diagram of the Zoning Code. The maximum density of the development shall not exceed the maximum density for the site, except where a density bonus for the provision of particularly desirable design amenities is allowed. The general residential product type shall be characterized by one to two-story, single family detached homes on large or medium size lots and/or clustered one to two-story, single-family detached units in projects with generous amount of open space, subject to conditions for varying residential use guidelines as specified by the Specific Plan for Sand Harbor. Details of the implementation of land use are further explained in Section 3.0. The Sand Harbor development is consistent with the Land Use Element of the City of La Quinta General Plan, which will designate this property to be Low Density Residential upon processing of the annexation, and zone change. The zoning is consistent with neighboring plans, as indicated by the Riverside County General Plan, which designates this area as a residential development. This development follows the policies set forth by the Land Use Element of the General Plan by providing existing setting and pattern of land use in La Quinta through the residential relationship to the surrounding projects. The Sand Harbor development will essentially create an extension of the Low Density Residential character as established through the policies provided in the Land Use Element of the City of La Quinta General Plan. 1.5.3 Housing Element According to the La Quinta Housing goals, specific plans and tract maps have already been approved for a large portion of the City and new residential development that is compatible with existing development is important in maintaining the quality of life highly valued by residents of the La Quinta community. The Land Use Plan locates higher density residential uses in areas close to employment centers, the Village, and major transportation corridors. The character of such uses is guided through sensitive design, buffering, 3 i ` - landscaping and screening techniques. The General Plan establishes land reserved for residential growth. These acreages include vacant and undeveloped lands presently within the City of La Quinta, thereby, encouraging in -fill development. The City of La Quinta's vision of the future for housing focuses on encouraging the provision of suitable housing for all City residents while maintaining and enhancing the City's high quality of life for its residents. Through its housing programs, the City will facilitate the maintenance and improvement of its existing housing stock resources, and encourage the production of a variety of new housing to meet residents' needs, while preserving the overall low density character of the City. The Sand Harbor development encourages the sensitive design unique to the area providing an in -fill to existing development that is currently zoned for low density residential as provided in the General Plan policies and goals. 1.5.4 Park and Recreation Element To adhere to the Park and Recreation element of the General Plan the Sand Harbor development will create a project design located in a residential area that is conducive to the City's integrated bicycle network. 1.5.5 Environmental Element The concern for environmental conservation associated with this project has been reviewed with the determination that development of the project will not endanger the quality and quantity of groundwater, and will encourage groundwater preservation through careful design of the site to retain storm water on site to retention basins. As specified in the goal of the Environmental Conservation policy (Goal 6-1 of the General Plan), the development will not deviate from providing a scenic view of the Santa Rosa Mountains. By utilizing a variety of alternative means to identify, preserve, and integrate historic and archaeologically significant sites and structures, the Sand Harbor development will follow the guidelines set forth through various studies to accommodate the objectives and goals set forth in the La Quinta General Plan Section 6.2.1. Also by incorporating available technologies of energy efficiency and energy conservation techniques, the project is hereby consistent with the General Plan goals as stated in Section 6.6. The City of La Quinta has geological and seismic guideline programs that produce lower hazards for its citizens. The Sand Harbor project will adhere to current structural building standards thereby reducing potential unsafe structures that would result from intensive land movement caused by earthquakes. 4 The northern area of the City is contained within a Blowsand Hazard Zone which will require blowsand reduction measures, such as vegetative cover and walls/screens and watering techniques intended to mitigate health and safety hazards as described in more detail under Section 3.8. Prior to disturbance of the land, the City shall approve development standards for conformance to the policies set forth. Adequate water supply will be installed to the project which is further discussed in Section 4.2. Creating an area exclusively for residential use provides no significant health and safety threat to the citizens of the City, but rather provides for developed land, thereby resulting in an anticipated decrease in incidents of possible future blowsand, which is currently recognized as a potential threat to surrounding residents in the area. 5 2.0 INTRODUCTION 2.1 Specific Plan Intent Wade Ellis, owner, has submitted appropriate applications requesting the City of La Quinta to approve a residential development at the northwest corner of Fred Waring Drive and Jefferson Street. Exhibit "8" presents a regional location map. Exhibit "C" presents the vicinity map and Exhibit "D" presents the site location map 2.2 Description The proposed development consists of 379 single family dwellings, providing three distinctive housing developments, all of which will be single family detached homes with intermixed open space areas within the development and around substantial portions of the project perimeters. Most of the open space serves a number of uses: visual enjoyment and relief, passive and active recreational purposes, and storm water retention. A meandering 6 -foot high decorative block wall will be situated an average of 20 feet inside of the perimeter property lines along both the Fred Waring Drive and Jefferson Street frontages. These perimeters will converge with the narrower adjacent portions of the public right-of-way to serve as landscape buffer areas. A main vehicle entryway is proposed for each of the two street frontages with entry treatments capitalizing on generous, lush amounts of landscaping. The location and design of the entryways will serve as graceful transitions as community entrances to the individual neighborhoods as described in Section 3. The creation of a strong sense of arrival to Sand Harbor will visually enhance the appearance of this housing community within the existing neighborhood in which it is proposed. The housing products will vary in size and will be placed on lots also varying in size. The west section of the project will have 118 lots providing upscale homes. The southeast section of the project will allow zero lot line construction with 10 foot separations between homes, also with detached dwelling units, explained further in Section 3.4.1. The northeast section will provide an area that adds a special character to its surroundings creating a housing community consistent with neighboring quality developments, such as Bermuda Dunes Country Club. Along the perimeter property lines adjacent to both of the street frontages, an 8 - foot wide meandering sidewalk is proposed. The sidewalk will encourage walking, bicycling, and jogging as an alternative to motor vehicle use, and is intended to permit user connection to future or existing sidewalks on adjoining properties. 9 REGIONAL SACRAMENTO MAI) SAN FRANCISCO SAN LUIS OBISPO LOS ANGELES SAN DIEGO /-10 SAN BERNARDINO CO. /-10 LAKE 'LAKE MATTHEWS PARRIS LAKE QCs`' ELSINORE PALM SPR/NGS BERMUDA DUNES LA QUINTA _ RIVERSIDE CO.

In addition, there is also an existing single family home subdivision called "Cactus Flower" on Fred Waring Drive to the southwest of the project. Jefferson Street and vacant land are located to the east. 2.4 Physical Description The project site is currently undeveloped open desert with sparse desert vegetation consisting primarily of creosote bushes. Variable topography exists with sand dunes ranging in elevation from 10 feet to 30 feet. Exhibit "E" and "F" show panoramic views. 2.5 Relationship of the Specific Plan to the General Plan The development of Sand Harbor will implement the goals and policies contained in the General Plan. All development within this project will be consistent with the provisions of the residential General Plan designation of the City of La Quinta. The project is consistent with neighboring plans, as indicated by the Riverside County General Plan, which designates this area as a residential development. The surrounding area is zoned for low density residential development similar to the character of development occurring south of Fred Waring Drive in the City of La Quinta, as stated in Chapter 2 of the Master Environmental Assessment for the City of La Quinta. The location of Sand Harbor at the northwest corner of Fred Waring Drive and Jefferson Street is designated by the Riverside County General Plan for low residential densities. Instead of the 7,200 square foot lot size minimum, average lot sizes within Planning Area 1 are proposed at 4,500 square feet. Planning Area 1 provides the option of having minimum lot sizes as low as 4,493 square feet (which is offset as per the proposed specific plan with generous landscaped open spaces). The open space in Planning Area 1 alone within the Sand Harbor Specific plan gives a generous amount of open space. In addition, 45 foot minimum lot frontage widths, zero ("0") and 10 foot lot line construction for side yard building setbacks are proposed for this planning area. Although a minimum 20 foot building setback is proposed in this planning area for all garages as normally permitted by the Municipal Code, this specific plan proposes the option of reducing the front building setback for habitable areas to 15 feet. 7 • . 1 #1 Corner of Jefferson & Fred Waring Dr. Looking Northwest COUNTRY_ CLUB DR.

As stated above, Planning Area 1 provides for 272,260 square feet of generous open space within this section of the Sand Harbor Planned Unit Development. Overall density of proposed homes correspond to the maximum number of residences permitted within the proposed General Plan Amendment to LDR and the RL Zone District representative of low density neighborhoods of 2 to 4 units per acre with one or two story dwellings in the form of detached or attached single family dwellings, town homes, or condominiums with generous open space subject to specific plan approval. 2.6 Relationship to Other Agencies Sand Harbor is located in an unincorporated area of Riverside County geographically connected to the City of La Quinta by Fred Waring Drive to the south. The City of La Quinta has expressed their interest in the project and will concurrently apply for Sphere of Influence ("SOI") and annexation through the Riverside Local Agency Formation Commission (LAFCO). Upon approval by City Council of concurrent entitlement application for Zone Change, General Plan Amendment, and Tentative Tract Map, City staff will process the annexation through LAFCO.

The minimum distance between buildings for this planned unit development will be ten (10) feet. Consistent with the overall layout, particularly affecting the smaller lots typical in Planning Area 1, front yard building setbacks are proposed to vary between 15 feet to 20 feet providing relief from °streetscape monotony", subject to future review by the City of specific building footprint plans. The Zoning Ordinance of Section 9.50.070 provides standards for the establishment of irregular lots requiring special measurement techniques in order to achieve the purpose of setback requirements. The following figure shows the standards to be used with this Specific Plan, should it deem necessary.

This planning area proposes zero ("0") lot line construction of building setbacks on one building side, and a minimum 10 -foot building setback on the opposite side (only when a minimum 10 -foot separation between homes is possible). The maximum lot size for this planned area is 7,869 square feet with an average lot size of 4,840 square feet. Varying building setbacks may be proposed to add more visual variety contributing to a "village" appearance. With exception of the homes to be developed on corner lots, zero ("0") lot line construction of building setbacks will assure 10 -foot wide separations between buildings. Instead of minimum 1,400 square foot dwellings, particularly affecting the smaller lots proposed, ranging from 1,200 square feet to 1,800 square feet are anticipated within this planning area with a maximum lot coverage of 45% to accommodate this particular planning area. The option of a rear -building setback of 10 feet is proposed. Lot widths are proposed to be a minimum of 45 feet to provide compensation for the zero lot line development. The proposal creates useable side yard space on at least one side of the yard adding greater standards than normally required in development standards set by the City of La Quinta. The design of homes within this planning area that are built on the zero lot line will minimize placement of windows facing the adjacent street, and incorporate obscure glass or glass blocks. Exhibit "H -a" represents Development Standard of Planning Area 1. 3.4.2 Planning Area 2 The northeastern section of the project consists of 129 lots with the smallest lot size at 7,495 square feet and the largest lot size of 15,196 square feet. The average lot size is 9,333 square feet. The front building setbacks will be consistent with the City of La Quinta development standards for Low -Density Residential. Planning Area 2 proposes lot sizes and homes meeting or exceeding the minimum specified within the Zoning Ordinance, with all lots exceeding 7,200 square feet and all proposed homes being 1,400 square feet or more (excluding garage areas). Lot widths meet or exceed the minimum of 60 feet as specified in the Zoning Ordinance for this zone and the side yard building setbacks are proposed to meet RL Zone District requirements of 5/10 foot in 11 } 1 I 1 1 1 1 1 1 2 1 3 I i 12 ICKI 106 100 `� 97 I 113 106 14 J1 104 I 1 I 1 M LL��II �I 1 1 - I 7 6 e $ __ f[i iI ..s 3 1 � I 1 1 21 � to 1 _ _ I t• q .. r p p 9 rs r �+ I 22 23 24 �. rIwo rn n. in Ll ia tea rti .r I .. .. 1 e7 4 77 r w f 1 N 75 I 74 N d I PLANNING AREA MAP PLANNING AREA 1 PLANNING AREA 2 PLANNING AREA 3 In 1N 1 COMMON OPEN AREA 1 r123124 I III 121 I N 113 I` e I °o° 120 iq 000 I _ 11• I 7 6 e $ __ f[i iI ..s 3 1 � I 1 1 21 � to 1 _ _ I t• q .. r p p 9 rs r �+ I 22 23 24 �. rIwo rn n. in Ll ia tea rti .r I .. .. 1 e7 4 77 r w f 1 N 75 I 74 N d I PLANNING AREA MAP PLANNING AREA 1 PLANNING AREA 2 PLANNING AREA 3 In 1N 1 COMMON OPEN AREA 1 r123124 �1Iftmer engineering Oft COUNESM01 RAW1431 LMD SURVElrl#* Exhibit "H" I III 121 I N 113 I` e I I 120 iq 114 I _ 11• TL-tt1t4 �1Iftmer engineering Oft COUNESM01 RAW1431 LMD SURVElrl#* Exhibit "H" 45' _ 45' _ _ 1 _ 45' 1 oa I Atrium 01 El Y >— W1 ;. f,,,�,, -_f � , l � I I Sid 1 Driveway ° 1 b -_----_--- ------------ -� - ---_-- --___ --- ° --- -- - N ° r I Exhibit "H -a" PLANNING PRIVATE STREET AREA 1 Typical Placement of Single~" Family Residences (Setbacks shown are typical) Scale: 1" = 20'-0" w W Fcc- W a CL 1�rner engineering I M I °.awo sUrvS vxa 55'- ° I --Zero (0'-0") Building Setback I 1 Covered do I I Residence;: CL UJ �- G.

Existing six-foot block walls around the perimeters of the adjacent subdivision were constructed in conjunction with its development. Subsequently, as part of the development of this subdivision, since these existing block walls currently appear to be free of physical damage with relatively no grade differences, it will not be necessary to construct new block walls corresponding to these areas. If damage to any portions of the existing walls should become evident, with permission of the adjoining property owner(s), appropriate repairs will be made matching that of the existing wall. 3.4.3 Planning Area 3 The entire western section of the project includes 118 lots with a minimum lot size of 9,235 square feet. Maximum lot size is 15,263 square feet with an average lot size of 10,932 square feet. This area will be designed for homes placed on lots with front building setbacks varying between 20 to 28 feet to avoid streetscape monotony. Planning Area 3 proposes lot sizes and homes meeting or exceeding the minimum specified within the Zoning Ordinance, with all lots in this area exceeding 7,200 square feet and all proposed homes being 1,400 square feet or more (excluding garage areas). Lot widths meet or exceed the minimum of 60 feet as specified in the Zoning Ordinance for this zone and the side yard building setbacks are proposed to meet RL Zone District requirements of an additional 1 foot setback for every foot of building height over 17 feet, up to the required setback of 10 feet as stated in Section 9.30.030 of the Zoning Code for the City of La Quinta. Maximum building square footage lot coverage on individual lots will not exceed 40% and all rear building setbacks will be a minimum of 20 feet. Similar to Planning Area 2, western perimeters of this planning area border a developed residential subdivision to the west. Existing six-foot block walls around the perimeters of the adjacent subdivision were constructed in conjunction with its development. Subsequently, as part of the development of this subdivision, since these existing block walls currently appear to be free of physical damage with relatively no grade differences, it will not be necessary to construct new block walls corresponding to these areas. If damage to any portions of the existing walls should become evident, with permission of the adjoining property owner(s), appropriate repairs will be made matching that of the existing wall. 12 3.5 Land Use This project has been developed to create a visually distinctive, environmentally sensitive neighborhood consisting of a variety of housing that relates to the desert and is unique, comfortable, and connected by attractive open space, landscaping, and a well -lighted street/sidewalk system. Sand Harbor blends in with the surrounding neighborhood housing projects, which are "Cactus Flower" located directly west on the opposite side of Fred Waring Drive; the "Bermuda Dunes Country Club" that is located to the north and west of the project and "Heritage Palms" is located to the south. Blending in with the surrounding neighborhood, this project fulfills the aesthetics of a residential community. The typical front building setback will vary, creating interest along the street. The staggered front setbacks of residences will help mitigate the proximity of buildings with regard to side -yards and distance between structures. Additionally, walking, bicycling and public transit will be encouraged by the design features of this project. Open space for the proposal consists of approximately 25 acres, which will serve dual purposes for recreational use and storm water retention (Lots "A", "B", "C", "D", "E", "F", "G", "H", "I", and "J"). Recessed portions of the open space areas will accommodate shallow on-site storm water retention needs and during most times of the year will provide generous areas for both active and passive recreation accompanied by "soft" landscape elements, accommodating areas for outdoor seating and picnicking. Elevated open portions of the space areas, not serving retention purposes, will offer the developer or home owners association the opportunity to add "hardscape" amenities, such as volleyball courts, community pools, tot lots, tennis courts, etc. To enhance the feeling of openness and to take advantage of the available view, homes with rear yards that back-up to the common open spaces (i.e., rear yards of homes backing -up to Lot "C" near Jefferson Street) will have rear block walls extending 2.5 feet high topped with decorative wrought iron further extending the wall height to 6 feet to match the perimeter walls and the wall heights separating individual yards elsewhere throughout the development. This combination wall design will not only enhance the appearance of the individual yards, but will serve to minimize concerns about safety and security in common open space areas that otherwise would be less visible if solid walls were installed. Exhibit "H -b" shows the wall concept presented. An integrated 4 -foot wide trail installed as a meandering sidewalk for walking or jogging is proposed along the raised perimeter areas of the open space areas, starting from the north portion of Lot "I", connecting southerly to Lot 13 7— 2' SQUARE PILASTER (REGULARLY SPACED) BLOCK WALL & PILASTERS (OPTIONS: UNWASHED SLUMPSTONE, SACK WASH SLUMPSTONE, SPLIT FACE, OR PRECISION BLOCK) EXHIBIT "H -b" Conceptual Combination Block Wall with Railing Scale: 1/2 inch = 1'-0" SOLDIER'S COURSE CONCRETE FOOTING BELOW Warmer 7 engineering "F," to Lot "C" along Fred Waring Drive connecting to Lot "D" along the south side of the Jefferson Street entrance, and returning the same way with the option of connecting to Lots "A", "B", "F", "G", "H" and finishing again at Lot "I". The ends of cul-de-sac streets that open to the open spaces areas will accommodate convenient access by most residents to this interior trail. Exhibit "H -c" identifies the location of the open spaces, prospective locations for "hardscape" amenities, and the integrated trail system. As part of the Site Development Permit process, more specific details for such proposed recreational amenities shall be supplied to the City for design review and/or approval, following guidelines established in the Zoning Ordinance of the City of La Quinta. As noted earlier in this report, the project currently is zoned for residential uses and lies within Riverside County. Upon presentation to the City of La Quinta, and concurrent with annexation to the City of La Quinta, the requested change of zone to "Low Density Residential" within a Specific Plan, will be consistent with the General Plan of the City of La Quinta. 3.6 Design Standards The building designs of the new residential structures shall emphasize a rural theme such as; Ranch, Western, Southwest, or Mission style neighborhood common to the Coachella Valley as stated in the Land Use Element of the General Plan. This project will present a unique sense of value and quality. The elements of style will include strong architectural wall massing with desert colored tile roofs. All roof and architectural projections, as well as balconies, exterior stairwells, and elevated decks will comply with Section 9.50.060 of the Zoning Ordinance. Sand Harbor will institute a balanced composition expressing order, but offering a variety of elements and materials to provide variation and richness within the common architectural theme. Any two-story home constructed along Jefferson Street, (a major arterial highway), as designated by the General Plan will be set back at least 150 feet from the public right-of-way. Each addressed dwelling unit will have illuminated numbers for easy identification mounted on contrasting backgrounds. The numbers will be of sufficient size to be legible from the roadway and situated near the roofline on the corners of the residence or within the immediate vicinity of the entry. The Sand Harbor development colors will be reflective of the architectural styles previously mentioned in this section and will encourage the following designs: 14 IC= C=== O LOT "A" LOT "C" t LOT "C" LOT "B- I C= B" A LOT .D" LC -T "K" (WELL SITE) I" LOT "J" 111 SCALE: 1 "=200' SAND HARBOR TENTATIVE TRACT MAP � N0. 29323 PREPARED BY: Warner engineering I 7 CIVILlN@1NE@AINOf PLANNING/LANA 9llIeVEYlN6 E 73-1 E6�� F,#��O, *mol 111 '*M *%M LAW ?

Entryway treatments, private street intersections, crosswalks: Major entries will consist of stamped colored concrete or laid bricks with contrasting smooth concrete bands. Individual driveways: Stamped colored concrete or laid brick will distinguish driveway transitions from private streets onto private properties. Interior development signage and methods of home address identification: Decorative low profile carved wood or simulated wood signs will serve as internal directional signs, to identify interior street names, and as address signs for individual residences and common area buildings. 15 Outdoor lighting on residences: Traditional heavy wrought iron Spanish, Mission, or Southwestern style light fixtures with semi-opaque glass and screened light sources utilized on the exteriors of building with illumination levels not exceeding 100 lumens with light cast in a downward direction whenever practical. Outdoor lighting elsewhere: Traditional heavy wrought iron Spanish, Mission, or Southwestern decorative light poles and standards will be utilized in common areas including along private streets, on entrance optional buildings or entry monuments and treatments, and common -use recreation and meeting place buildings that minimize transient lighting of adjacent properties utilizing shielded, directional, or recessed lenses. As for specific graphic representations of the architectural styles proposed, since this Specific Plan is intended to provide general design guidelines in this area, separate approval by the City of La Quinta will be required in the future of detailed designs and drawings as submitted for the Specific Planning areas by the developer. The following Table 1 enumerates standards to be implemented with this Specific Plan.

The HOA will enforce the street parking regulations on the private streets designated as "No Parking" and for "One Side Only" parking. Recreational vehicle parking will be consistent with Chapter 9.60.130 (D) of the Zoning Code which specifies for the storage or parking of recreational vehicles when parked in side or rear yards that have lawfully installed and permanently maintained solid walls or fences six foot in height, serving as visual screens. The area used for storage will be paved with concrete, asphalt, gravel, or other similar materials, and must extend to the width and length of the recreational vehicle. No recreational vehicle shall be parked or stored for more than 72 consecutive hours or for a combined total exceeding 72 hours during any seven (7) day period, on any private street location or combination of public street locations within the City. 3.6.2 Entrances/Access Based on preliminary studies of Sand Harbor Project, the following conclusions have been drawn: The site has an unencumbered direct access via Jefferson Street from Interstate 10 to Fred Waring Drive. The subject parcel fronts on both Fred Waring Drive and Jefferson Street, therefore drawing direct special advantages from both of these arterials. An additional emergency access road has been added which extends Minhoe Road abutting Bermuda Dunes Country Club to the west of the project. Additionally, the general layout of the many cul-de-sac streets accommodates emergency vehicle access ("EVA") routes to accommodate 9-1-1 emergencies both within the various sections of the development and adjoining properties. To the satisfaction of the Fire Marshal, the project will provide a Knox Box system that shall accommodate fire department access. 3.6.3 Transit and Circulation By providing the safest and most efficient roadway system possible, the project will implement special roadway corridor improvements which will be consistent with the unique character that the City of La Quinta seeks to establish. These improvements will include pedestrian walks, noise mitigation berms, street name signs, mailbox kiosks, and landscaping consistent with the themes suggested by the General Plan and as provided in this Specific Plan. 17 The Circulation Element of the General Plan outlines the design and location of required street improvements to complete the transportation system in the City of La Quinta. Sand Harbor will widen and improve adjacent portions of both Jefferson Street and Fred Waring Drive to General Plan standards. Two distinctive recessed community entries are proposed to and from the project site, one of each of the street frontages, located approximately 1,200 feet west of Jefferson Street on Fred Waring Drive and approximately 950 feet north of Fred Waring Drive on Jefferson Street. The entries will be recessed a distance of approximately 300 feet from the adjoining public streets. As residents and visitors enter the community, they will be greeted visually by a sense of greenness, openness, and order. The graceful entrance will flow with the perimeter landscaping and the meandering perimeter wall, thus setting a quality image. Visual continuity of the community entries are back dropped and reinforced by the park -like setting, tree lined streets, and the landscaping of the individual yards. Both of the perimeter public streets are to be improved as major or primary arterials, with 120 foot wide right-of-ways. As per City development standards, crossbars and stop signs will be installed as traffic control devices to accommodate traffic exiting the project site. Both of the project entrances will have 25.5 foot wide segregated entry -exit drive aisles with vehicle turn- around areas prior to gateway entry for refused entry, to minimize traffic congestion at these critical areas. The community circulation network is composed of a logical hierarchy of roadways, ranging from 41, 37, and 33 -foot wide streets, with the 41 -foot wide street serving as a "boulevard" throughout the development. As illustrated in the cross-section of the private streets, major interior roadways within the development will measure 41 feet in width, with streets tapering down to 37 feet for secondary streets and further down to 33 feet for local neighborhood collector streets, many of which terminate in 77 -foot diameter cul-de-sacs. According to the 1998 CA Fire Code Sec. 902.2.2.1, the Fire Department requires a minimum 20 feet of unobstructed widths. Due to minimized street widths, for all 33 foot wide neighborhood collector streets, on -street parking for guests of residents will be restricted to one side only. The requirement for the construction of bus turnouts and bus waiting shelters along the Jefferson Street and Fred Waring Drive frontages will be determined based upon the determinations of the Sunline Transit Agency and the City of La Quinta Public Works Department during their review of the companion Tentative Tract Map. If these improvements are to be installed, such work would be done concurrent with construction of any of the 3 planning areas upon demonstration of need for such services as deemed appropriate during Sunline Transit's review of the project. The design of the In bus turnouts and shelters will be subject to Sunline Transit Agency and the City Engineer's approval with coordination of any future street improvements that may be required to be integrated into the project's development. 3.7 Grading Plan, Erosion Control, and SWPPP/NPDES/PM10 3.7.1 Grading Plan Due to the nature of the existing terrain and drainage patterns on the site, in order to achieve the open space and retention areas as planned, grading of the project area will be done concurrently with soil stabilizers applied to exposed soil surfaces to mitigate fugitive dust particulate (PM 10) and to prevent wind and water erosion pending future development of the individual planning areas, which is expected to be done by different builders. Each planning area will be graded as development occurs within the specified individual planning area. As will be reflected on the development and grading plans, areas of the site will incorporate soil swales and undulating berming intended for not only retention purposes, but also to mitigate noise from recreational activities and to enhance a unifying rural character, theme, and sense of arrival consistent throughout the interior of the entire subdivision and the perimeters as viewed from the adjacent Jefferson Street and Fred Waring Drive. The pads will be established in each planning area for the individual homes, and it is expected that as much as 500,000 cubic yards of soil will be moved during grading operations in all planning areas combined. There will be no import needed on the site. 3.7.2 Erosion Control The grading operations shall include adequate provisions for water and wind erosion control both during, as well as after, grading operations have ceased. The details of erosion control shall be included in the project's Storm Water Pollution Prevention Plan ("SWPPP") and the small dust particles ("PM10") plan. The following are requirements for water and wind erosion control: 3.7.2.1 Prewatering: The site shall be prewatered to a depth of 3 feet prior to onset of grading operations. 3.7.2.2 During Grading: Once grading has commenced, and until grading has been completed, watering of the site and/or other treatment(s) determined to be appropriate shall be ongoing. 3.7.2.3 Post Grading: All disturbed areas shall be treated to prevent wind erosion control for the term that the area will remain undeveloped, even though it 19 may remain undeveloped for several years. Whenever feasible, final landscape and irrigation shall be installed. 3.7.3 SWPPP/NPDES/PM 10 In consideration of the periods of moderate to heavy wind conditions common to most of the Coachella Valley area, including this project area, windblown dust and sand are a concern when mass -grading operations must take place for large developments. Corresponding to the 3 -planning areas proposed, it is expected that there will be at least 3 phases where mass grading will occur, inclusive of common area development. The project will comply with the City of La Quinta's programs relative to SWPPP, NPDES and PM 10 Plans and will secure approval of such plan from the City Engineer. 20 r r 4.0 INFRASTRUCTURE, PHASING AND IMPLEMENTATION 4.1 Transportation 4.1.1 Traffic Impact A traffic impact analysis was completed by RKJK & Associates, Inc. on June 15, 1999. The development is proposed to generate approximately 3,627 trip -ends per day, with 284 vehicles per hour during the AM peak hour, and 382 vehicles per hour during the PM peak hour. According to an Initial Study/Mitigated Negative Declaration completed by Robert Bein, William Frost & Associates for the City of La Quinta (in cooperation with Coachella Valley Association of Governments, County of Riverside and the City of Indio) Jefferson Street will be widened to six lanes with construction scheduled to begin in November, 1999. 4.1.2 Community Entrance/Circulation The infrastructure circulation network is composed of interior 37' and 33' wide streets, two community entries, and a main boulevard. The main entrance on Fred Waring Drive will have a 70' right -of way which will taper into the 41' boulevard extending to the north, east and west through the project, branching out to 37' wide roadways. The cul-de-sac streets will have a 33' right-of-way. Exhibit 'T' presents a typical street cross-section design. 4.1.3 Project Identification Signage The main entrances into the Sand Harbor development will comply with the specifications for project identification signage in residential zones as described in Table 1602 of the City of La Quinta Sign Ordinance. As per the options specified in Table 1602, each of the two main entrances into the Sand Harbor development will be enhanced with project identification signage consisting of the following choices- Option hoices: O tion A - Wall -Mounted Signage: This choice of signage would be mounted on the decorative entry walls situated on both the right and the left sides of the main drive entries approaching the site from the public streets. The signs would be situated so that the top of the sign area would not exceed a maximum height of 6 feet from the adjacent finished grade, or to the top of the wall if building -mounted, and not exceed 24 square feet of face area per sign face, with indirect night time illumination.

The design and vertical location of either the wall -mounted or freestanding monument signage will be raised enough above the ground to accommodate the undisturbed vertical growth of low landscape shrubs and vines around the signs, so as to enhance the "natural" appearance, ambiance, and setting of development. All proposed signage will be subject to separate building permit approval as per La Quinta Municipal Code, Section 9.160.090. 4.2 Public Service 4.2.1 Sewer/Water Sewer service for the site will be provided by Coachella Valley Water District. Existing facilities include a 15 inch main in Fred Waring Drive. Connection to the service will be at the entrance on Fred Waring Drive extending into the main entrance with a 15 inch main and streets extending throughout the project with 8 inch lines. A 105 foot extension of the sewer system with 15 inch lines shall be installed along Jefferson Street traveling north from Fred Waring Drive. Water service will be provided by Myoma Dunes Water District. Existing facilities include a 6 inch main running north and south at the west side of the project within the Bermuda Dunes Country Club. Installation of a well site is planned at the farthest northwest corner providing a 10 inch main extending into the project with a 10 inch line installed throughout the main streets, with extensions of 8 inch lines provided on the collector streets within the project. Exhibit "J" presents the sewer and water plan in detail. 4.2.2 Drainage and Nuisance Water The project site consists of natural dunes; the topography is irregular with gradient slopes of 3% to 57%+/-. The design of the development will not cause any increase in flood boundaries, changes in water course levels, or frequencies in any area outside the development. Storm water falling on site during a 100 year storm event shall be retained within the development unless otherwise approved by the City Engineer. Retention basin slopes will not exceed 3:1. Maximum water depths will be 6 feet for common basins. 22 EXISTING 8" WATER 6 w b w EXISTING 6" WATER 6W'---EXISTING'---EXISTING 6" WATER —"�- CONNECT TO—` CONNECT TO---/ EXISTING WATER EXISTING WATER MDWS w 8 S a S 1a"W 8 S id"W ion N Z co w SCALE: 1 "=200' R�cc SAND HARBOR PREPARED BY: I ,Q 4 Warner - engineering _ -- Y - - phi/ '- — _ r.

Since the retention basins will also serve the recreational needs of the residents of the development, the 6 foot maximum basin depth is intended to minimize noise from recreational activities within these areas. Incorporating a retention facility design acceptable to the City of La Quinta Public Works Department, the retention basins will accommodate storm water run-off. The ultimate retention facility design will be based upon site-specific percolation data, which will be submitted for City review with the retention facility plans. Nuisance water attributed to the project will be segregated to separate collection facilities to be retained on site, and disposed of in approved facilities designed to contain surges of 3 gph/1,000 sq. ft. (of landscape area) and infiltrate 5 gph/1,000 sq. ft. It is anticipated that the amount of nuisance water will be reduced due to the use of water efficient landscape and irrigation materials throughout the development. The planting of hybrid Bermuda grass will be the predominant element within the landscape areas during summer months and rye seeded during cooler months. The larger open space areas will be landscape sculptured to appear as natural rolling berms, swales, and undulations to complement the ambiance of the development. The Specific plan incorporates the planting of drought tolerant species and installation of irrigation methods within a grading concept designed to retain storm water on-site as required by the City of La Quinta, with further discussion later within this section. 4.2.3 Development Although rough grading of the project site will be done concurrently with the application of soil stabilizers consistent with PM 10 (fugitive particulate dust) requirements and to prevent wind and water erosion on the site, actual finish grading, construction of homes, and common area improvements will be done independently as per the planning areas as proposed in production phases. Since each of the 3 planning areas will be available for construction independent of each other, it is not possible to identify which of the planning areas may first be constructed. However, construction of any of the 3 planning phases will include the completion of the right-of-way and landscape setback improvements on both of the adjoining street frontages and both entries. In instances where construction phasing does not coincide with development of complete streets, temporary turn -around areas meeting emergency access for the convenience of new residents will be installed with reflectorized temporary road barricades as per City development standards. 23 the amount of water used in a desert environment, where water is a limited resource, with a climate characterized by high levels of evapo-transpiration. The approach used in the landscape concept for Sand Harbor aims for a balance between retaining landscape plants indigenous to the desert, combined with a need to satisfy the desires of the existing community and future residents for greenery and lush landscaping. See Exhibit X" for Conceptual Landscape Design. The lush, oasis -like landscaping is planned for the yard areas of homes, active recreational areas and accent points in parkways at street intersections, and at project entrances. Landscaping of all yard areas fronting streets will be required to comply with the requirements of the conditions, covenants, and restrictions ("CC&R's"). Sand Harbor will have an overall theme and consistent appearance throughout, as reflected on the landscape plan. Similarly, all front yards of the development will shape a "look" of community, compatibility, and ease of maintenance. Landscape plant species are to be selected from a list of preferred landscape materials specified within this Specific Plan. The overall design and layout of front yard landscaping will be approved by the Sand Harbor Homeowners Association to assure a consistent, compatible flow from one lot to another. As noted above, a naturalized desert setting will distinguish the perimeters of the development along both Fred Waring Drive and Jefferson Street with the planting of drought -tolerant native and imported desert -compatible species in a landscape characterized by berms and swales, punctuated by a meandering 8 foot wide pedestrian sidewalk. A decorative 6 foot high meandering block wall will separate the 10 to 25 foot wide perimeter parkway from the lush greenery that will characterize the common area open space and storm water retention areas of the development. To provide relief from the intense summer heats, a combination of drought -tolerant and native species canopy trees will be planted in close proximity to benches and other passive recreational areas to provide comfort and shade to users. Trees planted within common recreation areas will include 24 inch size box specimen. 4.5.1 Landscape Concept The landscape design for Sand Harbor shall be based on the following zones for plant selection and irrigation systems: 27 r WEANDEFM WALX PEFDASTER WALL LAW AV %p d'0 Ole L r NOT MO SCALE Exhibit "K" �M- milmT MO CONCE i 1 �i LOCATION ZONE IRRIGATION DESCRIPTION Private yards Oasis Drip, bubbler, lawn Imported species Desert with oasis sprays Drip, bubbler and turf Street parkways Indigenous and imported (along Fred features species Waring Drive and Jefferson St. Transition from Drip, bubbler Indigenous and imported Project entries desert to oasis Drip, bubbler, lawn Active recreation _i Oasis _species Imported species and turf areas sprays Oasis Passive Drip, bubbler, lawn Indigenous and imported recreation areas sprays s ies See Suggested Plant Palette in Exhibit "L" All street parkways, project entrances and recreation areas, which will be incorporated in common open space lots, will be landscaped by the project developer with each phase of development. Installation of landscaping and irrigation systems for individual residential front yards will be the responsibility of the developer or home -builder to be completed prior to occupancy of the residence. This responsibility will be included in the CC&R's, accompanied by a requirement that the plant list identified in Exhibit "L" be used for all of the areas governed by this Specific Plan as described above. The CC&R's will also specify Homeowners Association ("HOA") maintenance responsibilities of identified front yard (and corner side yard) areas. The final landscape plan shall provide screening of cable and electrical boxes when applicable. The final landscape palette and proposed planting plan will be subject to specific review during the Site Development Permit process. 4.5.2 Landscaping Irrigation a. Only automatic and drip irrigation systems will be permitted for landscaped areas governed by this Specific Plan. This responsibility will be specified within the CC&R's.
