Site Development Permit 99-646; a request of Centex Homes for approval of architectural and landscaping plans for four new prototype residential plans to be constructed in Tract 21643 in PGA West. Associate Planner Leslie Mouriquand presented the information contained in the staff report, a copy of which is on file in the Community Development Department. 2. Committee Member Cunningham stated he liked the architecture as it works within the compatibility of the existing units and even broadens it. The applicant has done a great job and the units will stand out. The angle cuts are fresh and the designs will be an asset to PGA West. C:\My Documents\WPDOCS\ALRC3-4-99.wpd I 7,A.0 U 0 U 3 Architectural & Landscape Review Committee March 4, 1999 3. Committee Member Bobbitt asked if the applicant intended to plant any plant material on the garage trellis as indicated on the elevations. Mr. Forrest Haag, representing the applicant, stated it was intended to show what could be done. Committee Member Bobbitt asked who would be responsible for maintaining it if the homeowner did plant material as the homeowners' association would not. If the homeowner who buys the unit maintains it, there will be no problem. 4. Committee Member Bobbitt questioned the elevation where the garage shows tandem parking. Mr. Forrest Haag stated the one space furthest in was intended for golf cart storage. Committee Member Bobbitt asked what type units were being constructed. Mr. Forrest Haag stated they would all be single family detached. Committee Member Bobbitt asked if the courtyard would be maintained by the homeowners' association or homeowner. Mr. Clay Creel, architect for the project, stated anything behind the entry gate to the residence is the responsibility of the property owner. Discussion followed as to the landscaping responsibility of the homeowner and HOA. Committee Member Bobbitt asked about the colors being used as the proposed colors have not been used at PGA West before and they will stand out. Mr. Creel stated they are trying to introduce new southwest colors to provide variety. They will insure the colors are true to desert tones and will not be a pink. 8. Mr. Forrest Haag questioned staff s recommendation regarding Item #3. Staff is recommending the entry gates be decorative and matching. They would like this condition be removed as the entry gate will be the gate house gate and will be the responsibility of KSL Land Development. It will be the front door to the Centex tract but KSL has obligated themselves to construct it. Second, they would like to request that in regard to Item #2 of the recommendations, that since there have been new developments in the door materials, they be allowed to use a material that is compatible. 9. Committee Member Bobbitt stated the landscape palette is an improvement, especially where they are not using the messy trees in the patio and pool areas. 10. There being no further discussion, it was moved and seconded by Committee Members Cunningham/Bobbitt to adopt Minute Motion 99-005 recommending to the Planning Commission approval of Site Development Permit 99-646 subject to conditions as amended: C:AMy Documents\WPDOCS\ALRC3-4-99.wpd 2 Architectural & Landscape Review Committee March 4, 1999 a.) To Item #2 add, "or composite material'. b.) Item 93 removed Unanimously approved. B. Site Development Permit 99-647; a request of Century -Crowell Communities for approval of architectural plans for four prototype residential plans to be constructed on the east side of Tanglewood, between Arnold Palmer and Firestone and Canterbury at Riviera in PGA West. Commissioner Bobbitt excused himself due to a possible conflict of interest. 2. Associate Planner Leslie Mouriquand presented the information contained in the staff report, a copy of which is on file in the Community Development Department. 3. Mr. Kent Armstrong, Century -Crowell Communities asked that the requirement for the gate be removed and they be allowed to use some other garage material that would be compatible. He went on to explain how they had reduced the size of the pool in order to create two pools instead of one. There would be a total of 73 lots and three pools. 4. Committee Member Cunningham asked for clarification on the location of the pools. Mr. Armstrong identified their location on the map. 5. Mr. Paul Chasey, representing the HOA Association, stated they had met with Century and thanked them for trying to accommodate their needs. 6. Staff stated the pool was not an issue for this Committee and would be handled by the Planning Commission. 7. Mr. Armstrong stated the pool would be of the same size as the existing pools. 8. Mr. Chasey stated another of their concerns was the rear landscaping. Century had assured them it would be installed. 9. Committee Member Cunningham asked if the area was modified zero lot lines. Mr. Armstrong stated they were air space condominiums. The HOA takes care of the exterior landscaping and anything behind the gate to the residence is the responsibility of the homeowners. 10. Mr. Chasey stated they would like to see the front and rear landscaping plans to be sure they would be compatible with their existing system. Discussion followed as to the landscaping. C:\My Documents\WPDOCS\ALRC3-4-99.wpd 3'- �Q� Architectural & Landscape Review Committee March 4, 1999 11. Committee Member Cunningham asked if the HOA had any comments on the architecture. Mr. Chasey stated they had looked at the designs and in their opinion they were compatible with the existing units. 12. Committee Member Cunningham stated the architecture was compatible. He liked the overhang plastering effects and the designs were clean and crisp. He was concerned about the chimney caps and thought they should be reviewed by the HOA for compatibility. 13. Mr. Armstrong asked about the zero lot line in regard to the air conditioning units and where they could be placed. Staff stated that with air space units the City has left it to the HOA and developer to decide. Most of the HOA's have a form regarding intruding into the HOA open space and it can be worked out between the HOA and the developer. 14. There being no further discussion it was moved by Committee Member Cunningham to adopt Minute Motion 99-006 recommending to the Planning Commission approval Site Development Permit 99-647, subject to the recommended conditions with the following change: b. Delete Item 43 C. Chimney caps shall be decorative. d. Garage doors will be allowed to use other composite material. Unanimously approved. C. Site Development Permit 99-642; a request of Century -Crowell Communities for approval of architectural plans for three prototype residential plans to be constructed on the southwest corner of 501h Avenue and Washington Street in Duna La Quinta. 1. Principal Planner Stan Sawa presented the information contained in the staff report, a copy of which is on file in the Community Development Department. 2. Committee Member Bobbitt asked if these were the same plans as used at PGA West. Mr. Armstrong stated they were similar except for minor changes. Committee Bobbitt stated his concern regarding the use of date palms in the traffic areas and if they were to be used, they should be used away from heavy traffic. He had no objection to the remainder of the plant palette. 3. Committee Member Bobbitt asked if there were any requirements on this tract regarding pools. Staff stated there was no requirement on this tract. C:AMy Documents\WPDOCSVALRC3-4-99.wpd 4 4•U 006 Architectural & Landscape Review Committee March 4, 1999 4. Committee Member Cunningham stated that architecturally this tract will be upgraded. It is understated, but will work well at Duna La Quinta. 5. There being no further discussion it was moved and seconded by Committee Members Bobbitt/Cunningham to adopt Minute Motion 99-007 recommending to the Planning Commission approval Site Development Permit 99-642, subject to the recommended conditions. Unanimously approved. VI. CORRESPONDENCE AND WRITTEN MATERIAL: V. COMMITTEE MEMBER ITEMS: VI.

APPROVAL OF ARCHITECTURAL PLANS FOR TWO ADDITIONAL PROTOTYPE SINGLE FAMILY RESIDENCES UNDEVELOPED LOTS IN TRACT 25389 PHASES 3 & 4 IN LA QUINTA FAIRWAYS (SPECIFIC PLAN 83-001) Project Proposal The applicant proposes to amend Site Development Permit 98-619 by adding two additional prototype single family residential unit plans, each with two facade options, for Phases 3 & 4 of Tract 25389, within the southern portion of La Quinta Fairways (Attachment 1). No modifications are proposed for the previously approved landscaping. The project site is a private master planned golf -oriented resort community within Specific Plan 83-001. The site includes 24 lots (Lots 38 through 61) within Phase 3 of the subdivision, and approximately 33 lots to be created in Phase 4 (Parcel 1 of Parcel Map 24837) of the tract. The lots are located along Cypress Point and Breckenridge Drive at the southern portion of the La Quinta Fairways community. Lot sizes for the Phase 3 lots exceed 7,000 square feet. These lots are not fairway lots, but rather back onto each other or the perimeter of the La Quinta Fairways development. The applicant has submitted a portfolio (Attachment 2) including building elevations and floor plans with 2,004 square feet of liveable space for Plan 100, and 1,984 square feet of liveable space for Plan 200. Both of the proposed plans are for 3-bedroom, one story units. The maximum building height is 17-feet, except for chimney projections. Both plans are laid out in a predominantly square footprint with entries oriented within a front courtyard area. The 2-car garages are front loading with roll -up sectional doors. The roof lines consist of the main side facing gable and smaller hips. P:\LESLIE\ALRCrptSDP98-619Amd.#1 RJT.wpd 0- "0S A Mediterranean architectural style is proposed for the two units, with plaster walls and concrete S-tile roofing. The color and materials will be the same as for the original six prototype units approved in 1998. Proposed side and rear elevations are the same for both prototypes. The garage doors will be the same dark brown color as the first six units. The two new proposed plans provide for outdoor living area in the front of the units, since these lots are not adjacent to the golf course. By having the outdoor living area in the front, the exposure to noise impacts from vehicular traffic along Calle Tampico and Park Avenue will be reduced. The two new plans provide front courtyard enteries with masonry block walls in front of the units, similar to the original six RJT units. Landscaping will be provided on both sides of the courtyard walls and in rear yards. The future resident will have the opportunity to have private swimming pools and outdoor fireplaces in the front courtyards. Existing Unit Description The City originally approved the Duna La Quinta Specific Plan (SP 83-001) in 1984 which permitted over 1,200 dwelling units on 266 acres. Subsequent amendments of SP 83-001 have reduced the total number of residential units allowed to 966. The La Quinta Fairways development (previously named Desert Fairways) is Phase 8 of SP 83-001 allowing 300 residential units and golf course fairways on 94 acres (Attachment 1). The initial home builders of the La Quinta Fairways (Tract #25389) were Brock Homes and Jascorp. They built single family homes ranging in size from 2,204 square feet to 3,017 square feet on lots that front onto Del Monte Court, Indian Wood Court, Doral Street and Grand Traverse Avenue. The existing homes are one and two -stories and were built in the early 1990's. In the Mid-1990's, Fairways La Quinta acquired various single family lots in Tract #25389 (Phase 1) to develop 2,316 square feet and 2,424 square feet single story houses within five percent of the size of the existing homes. On September 12, 1995, the Planning Commission approved two additional houses that were 1,999 square feet and 2,300 square feet under Plot Plan 95-563 (Compatibility Review). The houses, built by Ayres Homes, were constructed on Spyglass Hill Drive with the exception of the model homes on Grand Traverse Avenue. Exterior finishes consisted of concrete roof tile with plaster cement walls (i.e., desert colors). Flat and shingle concrete tile roofing was permitted provided the houses were interspersed among houses with S-tiled roofs. Additionally, stucco boxed roof eaves of 18- inches were required to ensure the homes were similar in design to the existing homes. Ayres Homes completed the remaining lots of Phase 1. On March 10, 1998, the Planning Commission approved six new single family residential unit plans and associated landscaping for RJT Development. These units would complete the La Quinta Fairways community. The units ranged from 2,180 square feet to 2,610 P:\LESLIEWLRCrptSDP98-619Amd.#1 RJT.wpd 909 square feet, feature 3-bedrooms, and 2-car garages, with golf cart garages for four of the units. The architectural style is California Mediterranean with the houses having concrete S-tile roofs, exterior cement plaster walls and fascia treatments. Roof lines include hip and gable designs, and each house has two different street elevations. Construction of these units is underway along Castle Pines Drive. MANDATORY FINDINGS As required by Section 9.60.300 (Compatibility Review) of the Zoning Ordinance, the Committee is required to review and comment on the following architectural and landscaping findings: 1. The architectural and other design elements of new residential unit Plan 100 will be compatible and not detrimental to the other existing units in La Quinta Fairways, as this new unit plan will feature the same or similar design elements, such as front courtyards, garage door styles, a mix of hip and gable roof lines, chimney caps, and exterior cement stucco wall finish. However, of concern to staff is that the dominant roof ridge line on both units is continuous as viewed from the rear elevation. Staff met with the applicant and requested that the ridge line be broken up by some type of treatment on one of the plans in order to provide more interest, especially for those lots adjacent to Calle Tampico. The applicant responded with the redesign shown in Attachment 3, which features an integrated gable in the rear elevation of Plan 100 This adds design interest but does not break up the continuous ridge line. Staff recommends that one of the prototypes be redesigned to break up the continuous main ridge line. 2. The proposed detached single family residential units will be compatible to existing dwellings with respect to architectural materials such as roof material, stucco colors, garage door color and style, as the new unit plans will feature the same colors and materials, concrete roof tiles, and glazing. 3. At least one specimen tree (i.e., a minimum 24"-box size with 1.5" to 2" caliper measuring 10 feet tall from the top of box) shall be provided in the front yard or street side yard. 4. The project is consistent with the General Plan in that the new unit plans will be among other previously approved units constructed to complete Tract Map 25389 at La Quinta Fairways, a master planned private community. 5. The project is consistent with the Zoning Code in that the new prototype plans will meet all of the development standards of the RL Zoning District, including building height, building setbacks, and garage requirements. Staff received a letter, dated March 27, 1999, from a resident of La Quinta Fairways which states concerns about blowing dust and dumping of debris on Lot 20 of the first RJT phase. In order to P:\LESLIE\ALRCrptSDP98-619Amd.#1 RJT.wpd `. J 010 ensure compliance with Zoning Code Section 9.100.290 - Fugitive Dust Control staff is recommending that the developer landscape Lot 20 with a ground cover to be maintained until such time that a unit is constructed on Lot 20. 6. The project is in compliance with the California Environmental Quality Act requirements for environmental review in the form of EIR State Clearing House # 83061305 which was certified by the City Council on May 15, 1984, when Specific Plan 83-001 was adopted. 7. The design of the project, including but not limited to subdivision design, project enteries, interior circulation, pedestrian and bicycle amenities, screening of equipment, exterior lighting, and other design elements are compatible with surrounding development and with the quality of design within La Quinta Fairways and the City of La Quinta. 8. Landscaping for the project was approved on March 10, 1998, by the Planning Commission under Site Development Permit 98-619. The two new unit plans will not result in any changes to the approved landscaping plan. RECOMMENDATION: Recommend to the Planning Commission approval of Site Development Permit 98-619 Amendment 1, subject to the following conditions: 1. One of the prototypes shall be redesigned to break-up the continuous roof ridge line. 2. Landscaping shall provide for 24" box size tree sizes with 1.5' to 2" caliper measuring 10 feet from the top of box as per Section 9.60.300 of the Zoning Ordinance. 3. Lot 20 of Tract 25389-3 shall be landscaped with a ground cover and maintained until such time as a unit is constructed on the lot. Attachments: 1. Location Map 2. Application portfolio 3.

ED KNIGHT, PROJECT DIRECTOR) APPROXIMATELY 100 FEET SOUTH OF DESERT STREAM DRIVE AND ON THE WEST SIDE OF DUNE PALMS ROAD REQUEST: APPROVAL OF ARCHITECTURAL AND LANDSCAPING PLANS FOR THREE PROTOTYPE RESIDENCES IN TRACT 27519 (ALISO DEL REY) ARCHITECT: BENJAMIN AGUILAR AND ASSOCIATES LANDSCAPE ARCHITECT: IMA DESIGN GROUP INCORPORATED BACKGRO-UND: Rroject P_roDosal The applicant proposes three residential prototype plans each with three facade options within Tentative Tract Map 25719, a recently approved subdivision of 70 single family lots located south of the Topaz development. The prototype floor plans vary from 1,500 square feet to 1,718 square feet in size. Plan 5 can be increased to 2,008 square feet by converting the third car garage parking space to living space. All plans are one-story (14-feet to 16-feet high), and include attached garages for two or three cars. Model homes are planned for construction on Lots 41 and 42 under Minor Use Permit 99-122. A Mediterranean architectural style is proposed for the project, utilizing exterior plaster walls and concrete S-tile roofing. Desert color tones (e.g., various shades of brown and grey) are proposed for the exterior building surfaces. The material sample board will be available at the meeting. Proposed building sides and rears are similar in ,. 014 ALRC SDP 99-648 Century - 32 Page I of 4 design. The "C" building elevation has exposed rafter tails enhancing the architectural options. The typical front yard landscaping plan is attached. Front yards include a minimum of three to five specimen shade trees (i.e., 1 .5" and 2.0" calipers), and numerous shrubs highlighted by mounded lawn and/or groundcover areas. Shrub types vary based on location around the houses and exposure to the sun. Landscaping is also proposed for the retention basin and Dune Palms Road parkway, consisting of trees and shrubs clustered throughout. Lawn is used primarily for coverage in the retention basin. Access to the basin is provided by a concrete ramp located at the south side. Parkway walls are masonry clad in stucco with pilasters. Open wrought iron sections are proposed adjacent to the retention basin. Existing Eucalyptus trees along the north side of the retention basin will be retained, as required by the Tract approval. MANDA70RY-FINDINGS As required by Sections 9.210.010 (Site Development Permit) and 9.60.330 (Residential Tract Development Review) of the Zoning Code, the Committee is required to review and comment on the following architectural and landscaping findings: The architectural and other design elements of the new residential units will be compatible and not detrimental to surrounding developments. A minimum of two different front elevations, with structural changes (roof type, height, etc.) is required. Response: The applicant proposes three facades for each prototype house plan. The house plans are compatible with the surrounding Topaz homes because similar architectural features are utilized such as tile roofs, exterior plaster, sectional garage doors, etc. One problem with the house plans is that all prototypes propose the same main ridge line with side yard facing gables, excluding garage elevations. Staff recommends that the developer clip the gable sides of one elevation per prototype plan to provide a varied design theme. To enhance and break up the horizontal roof lines, staff recommends a shed dormer window or other design elements be added to two of the prototype units pursuant to the requirements of Section 9.60.330 (D2) of the Zoning Code which states: "No more than one of each prototype plan shall have a continuous (one height) roof (such as a hipped or gable) when viewed from the front and rear of the unit." 2. Project landscaping shall provide visual relief and complement buildings and parkway areas. ' 015 ALRC SDP 99-648 Century - 32 Page 2 of 4 A. Parkway/Retention Basin - The conceptual landscaping plan provides adequate coverage for designated common areas. However, plant sizes are not specified and palm trees should be added to the plant palette to supplement the use of pine trees along Dune Palms Road. Permanent irrigation and groundcover shall be installed in the existing Eucalyptus tree grove located to the north of the retention basin and behind some of the single family lots to the west insuring the trees remain healthy. The final landscaping plans shall be prepared to comply with the requirements specified in the Conditions of Approval for Tract 27519, requiring specimen trees, lighting, and earth mounding along Dune Palms Road. B. Front Yards - A varied plant palette is provided for the prototype houses. An adequate number of trees and plants are provided to accent the lawn and groundcover areas. Tree sizes are larger than required by the Tract conditions. Staff —Comments - The single story, prototype houses proposed by the applicant have distinctive architectural features that are attractive and compatible with existing houses in adjacent developments. The varied streetscape design creates aesthetically pleasing housing units, subject to conditions. RECOMMENDATLON: Recommend to the Planning Commission approval of Site Development Permit 99-648, subject to the following conditions: 1 . Final front yard landscaping and irrigation plans shall be submitted for review by the Community Development Department prior to issuance of the first building permit for these units. 2. Prior to final map approval by the City Council, common area landscaping plans shall be submitted for review by the Public Works and Community Development Departments, pursuant to the Conditions of Approval for Tentative Tract Map 27519. Mexican Fan palm trees (minimum 8' high brown trunks) shall be added to the planting program for Dune Palms Road. 3. Permanent irrigation and groundcover shall be installed in the existing Eucalyptus tree grove. 4. Each prototype house plan shall have one side building elevation that offers a clipped gable roof design. 5. A roof dormer window or other types of design treatments shall be added to the rear elevation of two of the prototype house plans. nlf ALRC SDP 99-648 Century - 32 Page 3 of 4 6.

Parkway landscaping of the area has been included into the scope of this project to allow coordination of the City's storm drainage improvements with the Citrus developer's required landscaping improvements. This project is proposed in response to public concern regarding the current disposition of the drainage channel. The City Council awarded a professional services agreement to Ray Lopez Associates (RLA), for the landscaping design of CIP 98-1 1 on September 15, 1998. Since that time, RLA has proceeded with the conceptual design and layout of the parkway landscaping improvements and has provided those layouts to the City for its review and approval. Protect Proposal Landscape Plans - Calle Rondo parkway - The landscape architect is proposing parkway landscaping improvements consistent with existing landscaping along the east side of the perimeter block wall. The proposed landscaping coordinates with the City's storm drainage improvements. The proposed landscaping will also allow for easy maintenance which will be provided by the City, due to the fact that the parkway serves as a City maintained storm channel. K\P W DEPT\PROJECTS\98Prlcts\9811 Rontlo-D1tch\Reports\990407a.wptl '' 0 1. The proposed plant material is limited to Bottle Trees, Bougainvillea, and Turf. The Bottle Trees will complement the existing trees on the east side of the Citrus perimeter wall, while the Bougainvillea is consistent with the landscaping which was recently installed along the Avenue 52 Citrus perimeter. The remaining landscaping will consist of Turf throughout the drainage channel area. No landscape lighting is proposed due to the occasional storm flow that will occur.

Q > OOIdWVl 371VO 1�Wdi11�i1. Bougainvillea Nyetaginaceae A small group of evergreen shrubs and vines that are among the most widely known flow- ering plants in subtropical regions around the world. Bougainvilleas come from many parts of South America and are ideally suited to warm coastal habitats but perform with equal success in most frost free regions, including the low and intermediate deserts. They pro- vide many landscape uses from vines on trel- lises, in containers, as groundcovers on slopes, and for cascading over walls. All types thrive in full sun and heat, require well drained soils, and low amounts of supple- mental water. Too much water, particularly during late spring and summer, encourages more foliage growth and less Flowering. Young plants should be installed with care. Root balls are easily broken and careful handling is often recommended to reduce root damage and shock. Once established, bougainvilleas can be quite carefree. Fertilizing and pruning in early spring can help improve growth and shapes of these plants. All varieties are damaged by frost; young plants are often killed. Watering in late summer also can stimulate additional growth that is highly sensitive to frost. Most cultivars available in nurseries are hy- brids among three closely related species: B. glabra, B. peruviana, and B. speetabilis (B. brasiliensis). These species vary in size, produce bright rose to purple -red flowerbracts, and usually have sharp spines on their stems. Widespread interest in these specieshasledto the development of new hybrids that now provide many flower, foliage, and growth characteristics for garden use. Flowers are actually small and white; the color value of these plants is caused by brightly colored leaf bracts. These bracts can be single or double and range from pink, purple, white, rose, and orange. Plants vary in habit, from dense, mounding shrubs to vigorous woody vines. The wide may of choices has led to some confusion among certain names and plants. Several popular varieties are noted below. Plates 159 - 171. Mounding shrub types: R 'Crimson Jewel'- Brilliant glowing red bracts. B. `La Jolla' - Fluorescent red bracts, compact, bush form, 12-20 ft. B. 'Raspberry Ice' (B.

Most species come from Australia, where they exist in widely varying habitats, from rainforests to dry inland regions along seasonal watercourses. Three species are commonly found in land- scape use in western gardens, one being best adapted to and and warm landscapes. Brachychiton populneus (Sterculia diversifolia) Kurrajong Bottle Tree A small to medium evergreen tree, 30-45 ft. tall. Young trees develop an upright habit; mature plants have a round dome shape. Fo- liage is comprised of glossy, medium green leaves, 2-3 in. long; inconspicuous bell -shaped flowers are creamy white with rose inside and are produced in large numbers in early spring. Large clusters of woody seed pods are pro- duced in summer. Kurrajong bottle tree is native to foothills and plains throughout inland parts of eastern Austra- lia, where it is adapted to humid and semi -arid climates, warm temperatures, and seasonal drought. The mean annual rainfall within its natural habitat averages 17-30 in. and occurs evenly all year. Plants will grow in drier areas along seasonal water courses, where they can obtain addidonalmoisttueforlargergmwth. Soils are often rocky, poor in value, and well drained. This species is appreciated for its fresh green foliage, shimmering leaf character, and toler- ance for heat, sun, and aridity. It is widely used in coastal and inland areas as a street tree, in parks, and as a shade tree in residential gardens. Young plants do best with low to moderate amounts of supplemental water; established plants are quite drought tolerant. It is also a very popular shade tree in lawn areas in low and intermediate desert regions, where warm tem- peratures and regular water stimulate very fast growth. Good drainage is preferred; excessive watering can lead to root rot problems in poorly drained areas. Litter from leaves, flowers, and pods can be objectionable. Plates 172 - 175. 172.
