This meeting of the Architectural and Landscaping Review Committee was called to order at 10:09 a.m. by Planning Manager Oscar Orci who led the flag salute. B. Committee Members present: Bill Bobbitt, Dennis Cunningham, and David Thorns. C. Staff present: Planning Manager Oscar Orci, Principal Planner Stan Sawa, Associate Planners Greg Trousdell and Martin Magana, Management Analyst Debbie Powell, and Executive Secretary Betty Sawyer. Il. PUBLIC COMMENT: None. III. CONFIRMATION OF THE AGENDA: IV. CONSENT CALENDAR: A. Staff asked if there were any changes to the Minutes of April 2, 2003. There being no corrections, it was moved and seconded by Committee Members Thom/Bobbitt to approve the Minutes as submitted. V. BUSINESS ITEMS: A. Tentative Tract Map 30521; a request of Cornerstone Developers for review of street perimeter landscaping plans for La Quinta Del Oro located at the northeast corner of Washington Street and Miles Avenue. Principal Planner Stan Sawa gave an overview of the project and introduced Mr. Ray Lopez, landscape architect for the project, who gave a presentation on the project. 2. Committee Member Thorns asked if the area to the east, that contained grass, had a curved sidewalk. Mr. Lopez stated there was a meandering sidewalk. Committee Member Thorns asked if G:\WPD0CS\ARLC\5-7-03.wpd I •.6.0 J 004 Architectural & Landscape Review Committee Minutes May 7, 2003 the applicant was using the taller palm trees because they were available. Mr. Lopez stated the owner of the project had another project in the City of Indio where approximately 300 palm trees and will have to be removed he would prefer to transplant them than destroy them. Committee Member Thorns asked if Mr. Lopez would be selecting them personally. Mr. Lopez stated yes and he would be doing the planting design only and not the sidewalk. Committee Member Thorns asked if Mr. Lopez would be doing the drawings for the sidewalk or just the planting plans. Mr. Lopez stated he would be doing the planting. The layout of the sidewalk and the wall is done by the civil engineer. Committee Member Thorns stated the design of the sidewalk and the grading, not the engineering portion, should be done by the landscape architect. Mr. Lopez stated he did work with the civil engineers to design them, but he wanted it on their plans so when the grading is done, they know where the wall and sidewalks are going. Committee Member Thorns stated he would like to see the landscape architect more involved in the design portion of the entire project. He asked that his comments note that he would like to see the landscape architect provide a concept grading and sidewalk plan prior to the civil engineer plans being prepared. He believes the landscape architects has the ability to design the sidewalk and that the civil engineer should do the engineering. On this project the walk and planting location especially. He has no problem with the design of this project. 3. Committee Member Bobbitt asked if Mr. Lopez had any experience with the aluminum edging that is proposed. Mr. Lopez stated he is using it on his own home and it held up very well. Committee Member Bobbitt stated that under certain soil conditions it will deteriorate. He is concerned about it being so thin and under regular maintenance, edgers will not be able to be used. Mr. Lopez stated there is very little area to be edged and he would not be adverse to installing a concrete mow strip instead. Committee Member Bobbitt suggested using the composite border boards or even better, concrete. In regard to pulling date palms out of a grove that may not have been watered and maintained, may have been stressed over any period of time and this stress will show up at the crown. He strongly recommended Mr. Lopez hand pick the best trees. He asked what type of material would be used on the perimeter wall. Staff stated it had not been determined. G:AWPDOCSVARLCA5-7-03.wpd 2 i 0 0t '{'U G Architectural & Landscape Review Committee Minutes May 7, 2003 Committee Member Bobbitt asked if any vines would be used. Mr. Lopez stated only at the entry around the date palms trees for vertical color. He stated they were considering planting shrubs in front of the wall. Committee Member Bobbitt asked staff to pay attention to what type of material is used on the wall as most of the plants are low and design will be important. The wall will need some type of architectural style. Mr. Lopez stated they have been looking at the existing wall to the north. It is stuccoed with a reveal and they are looking at options such as making a transition with a pilaster. 4. Committee Member Cunningham stated they should submit three concepts for review. Mr. Lopez showed an example of one they are considering. Slumpstone is one material they prefer and he showed examples of wall materials they were considering. Committee Members commented on the examples. 5. Committee Member Thorns asked that it be a light colored wall with squeeze joints, a square double detailed cap with natural cement joints, laid up in a soldier coarse with a different complimentary contrasting color. 6. There being no further discussion, it was moved and seconded by Committee Members Cunningham/Bobbitt to adopt Minute Motion 2003-01, approving the preliminary perimeter landscaping plans for Tentative Tract Map 30521, as amended: a. A concrete mow strip shall be provided; b. Perimeter wall be a light colored slump block wall, with squeeze joints, light, a square double detailed cap laid up in a soldier course with different complimentary contrasting color. C. Landscape architect to pick the field palm trees. d. Landscape architect shall submit a concept grading walkway layout path to be reviewed and approved by staff prior to the civil engineer drawings being prepared. Unanimously approved. B. Site Development Permit 2003-754; a request of Ross Canon/Marinita Development Company for review of architectural and landscaping plans for a shopping center located at the southwest corner of Jefferson Street and Fred Waring Drive. G:\W PDOCS\ARLC\5-7-03.wpd 3 •s.JU 006 Architectural & Landscape Review Committee Minutes May 7, 2003 1 . Associate Planner Martin Magana gave a report on the request and introduced the project's representative, Mr. Ross Canon, applicant, Mr. John Berg, engineer, and Mr. Charlie Trokage, architect for the project, gave a presentation on the project. 2. Committee Member Cunningham asked what was (happening west of the project. Mr. Canon explained it was open space with a park, well site, and retention basin. 3. Committee Member Thorns asked for a definition of the truss look on the top. Mr. Canon stated it was a treatment ,given to the top of the building to break them up. It will be a scoring in the stucco for a shadow effect. Committee Member Thorns stated he likes the architecture and it has a good color selection. His objection is that all shopping centers are a function of the neighborhood and look the same. The design is dictated by major tenants which do not normally lend much to architecture. This, however does have good architecture in breaking up the mass of the buildings. He just does not see the creativity in the site plan. It seems the architect shows little imagination. It would be nice to have something different. Mr. Canon stated the site design is dictated by the major tenant. Committee Member Thorns stated they should not be governed by the tenants requirements. Mr. Canon stated they chose to use a landscape architect to break up some of the parking lot. Committee Member Thorns stated he believes the landscape architect should take the niche areas and create more people spaces. Mr. Canon noted the area they had provided for pedestrian use. Committee Member Thorns noted this is only one space and there should be more of these in the Center. 4. Committee Member Cunningham stated the buildings are architecturally alive and have enough articulation to make it look more like a village center. He agrees with Committee Member Thorns in regard to the pedestrian collector area. His objection is the rear elevation. Mr. Canon stated they are intending to plant trees to screen it from the west. 5. Staff stated that the General Plan designates a secondary gateway for the City at the southwest corner of Jefferson Street and Miles Avenue. Committee Members asked who would be responsible for reviewing the design. Staff stated it is yet to be determined. Committee Members asked that the design of the City gateway sign come to this Committee for review. �S,O u 007 G:\WPDOCSWRLC\5-7-03.wpd 4 Architectural & Landscape Review Committee Minutes May 7, 2003 6. Committee Member Bobbitt stated he too is concerned with the rear elevation. He appreciates that no plantings are next to the building. Commercial developments typically have too many plant beds where pedestrians will walk through them and they become unattractive. It appears Brachy cyiton (Bottle Tree) are to be used and they are a messy, hearty tree and in this location it might work. The Rhus Lancea is a supple tree that will require double staking and it is in a narrow area and they ideally need an area that is 8 X 8. There needs to be some type of plantings/trees that will stand up by themselves. The Sumac would be an excellent example. The growth habits need to be considered when determining what to use where. Discussion followed. 7. There being no further discussion, it was moved and seconded by Committee Members Cunningham/Thorns to adopt Minute Motion 2003-017 approving Site Development Permit 2003-754, as amended: 1. More people spaces shall be created by the landscape architect. 2. Incorporate some decomposed granite in the planters between the car overhang and the western property line. 3. A different type of tree that is substantial on its own to be used in the parking lot. 4. The Secondary Gateway sign design at the northeast corner of the site shall come back to the ALRC for review. 5. More sensitivity given to the rear elevation with planting. Unanimously approved. C. Site Development Permit 2003-764; a request of Paul Ehline/Medallist Development, Inc. for review of landscaping plans for four prototype units at PGA West Norman Estates located at 81-480 Madison Street. 1. Associate Planner Martin Magana gave an overview of the project and introduced, Mr. Frank Scole and Paul Ehline, landscape architect and developer for the project respectively, who were available to answer questions on the project. 2. Committee Member Thorns stated he likes the models but it needs a better roof treatment such as the better "S" tile. G:\WPDOCS\ARLC\5-7-03.wpd 5 Architectural & Landscape Review Committee Minutes May 7, 2003 3. Mr. Scole explained there will be a two piece barrel made of concrete to create a more authentic Spanish look. 4. Committee Member Cunningham stated he defers to the architect and developer for projects that are behind gates. They will suffer for the lack of detail. If the buyers aren't there, they will change the style. The market will make the determination. A consideration may be to lower the pitch to allow less roof to be seen. Staff stated the buildings are at 22 feet. 5. Committee Member Thorns agreed, but when something is shown at this meeting, to him that is the example of what is proposed to be used. Applicants should be showing what will be used. He understands they are market driven. If the attitude of the Committee is to allow the developer to make that determination he does not see why the projects should be brought before the Committee. 6. Committee Member Bobbitt stated he likes the units and the comments on the roof are well stated. 7. There being no further discussion, it was moved and seconded by Committee Members Thoms/Cunningham to adopt Minute Motion 2003-018, approving Site Development Permit 2003-764, with the following recommendations: a. The roof treatment as verbally presented by the architect shall be used. Unanimously approved. D. Site Development Permit 2003-768; a request of Santa Rosa Builders for review of architectural and landscaping plans for Tract 30487 located on the north side of Avenue 58, south of PGA West and west of Madison Street. 1. Associate Planner Greg Trousdell gave an overview of the project and introduced Dave Brudvik, representing the project, who gave a presentation on the project. 2. Committee Member Thorns stated this is an exciting plan even though it is located on a long lot. He asked who designed the G:\WPDOCS\ARLC\5-7-03.wpd 6 .F.�( ' 0 0 9 Architectural & Landscape Review Committee Minutes May 7, 2003 retention basin planting schemes in the front of the project. Mr. Brudvik stated they were his landscape architects (Casa Verde Landscape), who were unable to attend the meeting. Committee Member Thorns stated the planting designs are not very good. It appears to be complicated and probably not what they want at the front of the project. The street exposure is like the front yard of a house. This needs to go back to the landscape architect as it is too complicated for this project. Staff gave a history of the project. 3. Committee Member Bobbitt asked if the French doors were to be made of wood. Mr. Brudvik stated it is not wood, but composite wood material. 4. There being no further discussion, it was moved and seconded by Committee Members Thoms/Cunningham to adopt Minute Motion 2003-019, approving Site Development Permit 2003-768, as amended: a. The five retention basins shall be redesigned by the landscape architect and reviewed and approved by the Community Development Department. Unanimously approved. E. Site Development Permit 2003-769.; a request of Jim Hayhoe for Mike Lang for review of architectural and landscaping plans for Tentative Tract 31289 located at the northeast corner of Caleo Bay and Via Florence within lake La Quinta. 1. Committee Member David Thorns excused himself due to a potential conflict of interest due to the proximity of his residence to this project and left the room. 2. Associate Planner Greg Trousdell gave an overview of the project and introduced Ray Martin, landscape architect, who gave a presentation on the Caleo Bay parkway landscaping. 3. Committee Member Cunningham stated he likes the visual relief for Lake La Quinta to take the residential out to Caleo Bay to make them mini -estate houses. G:\WPDOCS\ARLC\5= 7-03.wpd 7 Architectural & Landscape Review Committee Minutes May 7, 2003 4. Committee Member Bobbitt stated the Pittosporm "Wheeleri" and Agapanthas will burn in the summer heat (on the west exposure) and the buxus are bad over the long term. They need more sun tolerant plants. 5. There being no further discussion, it was moved and seconded by Committee Members Bobbitt/Cunningham to adopt Minute Motion 2003-020 approving Site Development Permit 2003-769, as amended: a. The applicant shall revise the plant pallette to utilize more sun tolerant plants. Unanimously approved with Committee Member Thorns being absent. Committee Member Thorns rejoined the meeting. F. Commercial Property Improvement Program 2003-022.; a request of La Quinta Real Estate -Rupert Yessayian for review of a request fund exterior improvements at 78-023 Calle Estado. 1. Management Assistant Debbie Powell gave an overview of the project and introduced Rupert Yessayian representing the project, who gave a presentation on the request. 2. Committee Member Cunningham stated this is what the program was designed for in the Village area. Committee Members Thorns and Bobbitt agreed. 3.

REQUEST: ARCHITECTURAL AND LANDSCAPING PLANS FOR A ± 20,000 SQUARE FOOT MUNICIPAL LIBRARY AT THE LA QUINTA CIVIC CENTER LOCATION: 78-275 CALLE TAMPICO Please prepare your comments on this proposal for discussion at the meeting. The project site is located within the La Quinta civic center complex, north of the senior center and west of City Hall. The site has been graded and the parking lot constructed. The City is proposing a 20,000 square foot building shell of which 10,000 square feet will be used for the library. The balance of the interior space will be used for other civic uses until the funds are acquired to expand the library to the full 20,000 square feet. The rooflines of the main library space and the central octagonal are consistent with the scale of the City Hall and Senior Center. Site design include an entry plaza, adjacent to the parking area, a new walled courtyard north of the community room, and a linear trellis along the west elevation of the library that connects the entry plaza to the separate entry for the community room and technical services area. The wall enclosing the community room courtyard also functions as signage, identifying the library to vehicular and pedestrian traffic on Calle Tampico. Additional low planter walls, similar to those at the City Hall, have also been incorporated to enhance the P:\Oscar\LQ Library\ALRCstfrpt.wpd.wpd .&.0 U 018 connection between building and site. A covered arcade is located on the west elevation, to provide a shaded transition zone between the entry plaza and the actual front door of the library. Architectural plans are attached (Attachement 1). The library's exterior materials and colors are compatible with those employed on the City Hall and consist primarily of stucco plaster walls, terra cotta tile roof, decorative tile accents, and metal trellises and trim. Details of the materials palette are illustrated on the finish presentation boards, which will be presented at the meeting. The landscaping design shall be consistent with and connect the Civic; Center Campus to the library site, by means of paving materials, low garden walls, and planting.

TWO-STORY OFFICE BUILDING IN THE LA QUINTA PROFESSIONAL PLAZA (PALM DESERT NATIONAL BANK COMPLEX) LOCATION: PARCELS 6 & 7 OF PM 29889 - EAST SIDE OF WASHINGTON STREET, ±300 FEET SOUTHEAST OF AVENUE 47 (SEE ATTACHED VICINITY MAP) Please review the attached information for the June 4, 2003 ALRC meeting. This proposed building incorporates the general architectural characteristics set forth in the approved La Quinta Professional Plaza Specific Plan (the architecture and landscape criteria of that plan are attached), and is consistent with the design of other buildings previously reviewed for this complex. There are minor variations in exterior treatments and accents, but they maintain the continuity of the overall architectural theme of the Specific Plan. The architecture also serves to carry over the copper rotunda element of the Palm Desert National Bank building, which is located at the northeast portion of the site. In regard to landscaping, no plans were submitted with this application, as the major landscape components have been installed with Phase 1 . There will be minor infill landscape improvements for planter and other areas surrounding the building. These improvements shall be consistent with the approved landscaping concept as approved for the Specific Plan, which was reviewed by the ALRC in 2001. Staff recommends adoption of a minute motion accepting the plans as proposed. Transmitted by: Wallace Nesbit, Associate Planner C:MR KG RP\ALRC\ALRCSDP771. DOC 'h.Ok 020 .boo, 0l1 N V. DESIGN GUIDELINES" The Design Guidelines for the Specific Plan have been developed as a method of achieving a high quality, cohesive design character for the development of the La Quinta Professional Plaza in La Quinta. They provide specific design criteria for the development of the project, as well as encouraging creativity, imagination and a high level ofharmony and consistency within the surrounding community. Adherence to the Design Guidelines will create a desirable asset to the community and enhance the project's overall value. These guidelines will govern the design quality of the project for application in the following ways: • To provide the City ofLa Quinta with the necessary assurance that the Specific Plan area will develop in accordance with the quality and character proposed; • To provide guidance to developers, builders, engineers, architects, landscape architects and other professionals in order to maintain the desired design quality; • To provide guidance to City staff, the Planning Commission and the City Council in the review of construction plans for the Specific Plan area. A. ARCIRTECTURAL GUIDELINES The building design of the mixed use complex utilizes a contemporary interpretation of Early California Spanish Architecture. Utilizing smooth textured plaster, mission clay tile roofs, deep recessed overlays, simple (but bold) detailing, interspersed with natural stone to provide the development with a sense of character. The bank building sets the tone for the remainder of the development. The hexagonal element that raps around the corner should become a landmark for the development. The stone and tile tower at the south end of the building identifies the main entrance of the bank. The architecture proposed for the project is shown on Figure 20, Bank Building Elevations. The bank building floor plan is shown in Figure 21, and the roof plan in Figure 22. To promote the campus like nature of the development the two-story buildings are clustered, with each building cluster's second story element linked with balconies. Many of the office buildings within the complex will be two-story and linked by covered walkways and connecting balconies. This will give continuity and ease of movement through the spaces, and give the office portion of the development its own identity. Figure 23 illustrates the architectural treatment of the conceptual office buildings. Mass & Scale Varied proportions are encouraged. Elements in facades should be spaced at varying intervals to create a visual rhythm. Each building will incorporate a continuity of mass, scale and architectural features. Office square footage will be distributed among multiple buildings as to break up building mass. Roof Treatments • Appropriate use of flat, hip, shed, and pitched gable roof forms are encouraged while barns, 11 The temporary bankfacilily as previously detailed precludes Design Guidelines. April 18, 2aat - Page 13 .t,.J- 023 and false roofs should be avoided. • Flat roofs may be used with a parapet alone, or in combination with other roof forms. • The use of variable ridge lines on a single structure is encouraged. • Roof pitch may vary between elements of a structure. • Mechanical equipment may be placed only on flat portions of roofs provided that they are screened from public view and that the screening is incorporated into building design. Architectural Features and Details • All mechanical equipment including fuse boxes, heating and cooling devices and satellite dishes shall be screened from public view. Screening devices shall utilize the same materials and colors as the main structure. • The use of curtain walls is not allowed. • Exterior walls should emphasize shadow relief using recesses, bays, and covered walkways. • Building entryways should be visually emphasized. • The use of false facade treatments should be avoided. • Shaded walkways will be provided for second story elements. • Conversion of first floor windows to exterior tenant entries is allowed subject to Staff approval of architectural details. Car Ports • Car ports should be designed to be architecturally compatible with the proposed building motif. • Acceptable construction materials are steel, wood, concrete and plaster. • Pre-engineered, lightweight steel structures should be avoided. Materials & Colors • The facade plays an integral role in building appearance and should use a continuous palette of similar materials and colors. • Restraint should be exercised in the number of materials and colors selected for a given structure. Accent colors should be limited to one or two per structure. • Acceptable construction materials are steel, wood, copper, stucco, concrete, plaster, ceramic tile, natural stone, aluminum and glass. • Muted colors are encouraged for large areas such as walls while brighter colors maybe used for accents. (Examples of muted colors include off whites, pastels, browns, ochres, and rusts.) • Architectural details should be painted to match the facade. B. SIGN GUIDELINES This sign program is conceptual only. A detailed sign program will besubmitted and approved before issuance of the first building permit.

The applicant has requested to meet before the ALRC in order to present their concepts and ideas for development of the perimeter areas surrounding The Esplanade residential project, and to gain clarification and direction on landscaping treatments within these areas. This is intended as an informal presentation of various ideas to the Committee for their consideration and further direction. The applicant has indicated that they would like to address the corner entry design issues raised by the Committee during the original review of the perimeter landscape concept on February 5, 2003 (meeting minutes attached). At that time, the Committee instructed the applicant to return with some conceptual treatments for the corner entry, and to refine the remaining perimeter areas. The applicant would also like some input from the Committee on their idea of incorporating street furniture, such as benches, in to the perimeter sidewalk areas. The applicant will provide graphic information on this as part of his presentation. Preliminary discussions with Public Works have indicated that there are no concerns with this, if such improvements are placed within the applicant's landscaped setback area, where maintenance and replacement costs would be their responsibility. Staff recommends no specific action be taken at this time, beyond any direction to the applicant as the ALRC may feel to be appropriate. Transmitted by:.

Wpd Architectural & Landscape :Review Committee Minutes February 5, 2003 Committee Member Cunningham asked how the individual homeowners' walls are constructed when they landscape the interior lots. Mr. Lopez stated it is all private and handled through the CC&R's and with the homeowners' association (HOA). Committee Member Cunningham suggested they request Art and Public Places funds for the corner. He further asked if the City has any stipulation requiring only male palms on street side. 9 3. Committee Member Bobbitt asked about the planter area outside the sidewalk along Fred Waring Drive. Mr. Lopez stated all the plant material for this area is low growing or where it is no more than two feet he leaves it as decomposed granite (DG). Committee Member Bobbitt stated it is a problem maintaining plant material too close together, or at the edges. It is trimmed too closely and becomes unattractive. Mr. Lopez stated they were using Red Yucca or.something like where it is a problem. Emitters are also a problem as to their location. Committee Member Bobbitt asked if there was a reason the entrance islands have a different variety of trees along Fred Waring Drive. Mr. Lopez stated it was just to have variety. Committee Member Bobbitt suggested using the standard or multi -trunk palms, as some species are very prone to wind damage. The multi -trunk are better. Mr. Lopez explained the perimeter is multi -trunk and the interior would be the standard. Committee Member Bobbitt suggested the majority be multi -trunk. He then asked what was proposed for Lot C. Staff stated the entire landscape area is labeled Lot C. Mr. Lopez stated it would be a passive recreation area. Committee Member Bobbitt asked what type of material the exterior wall would be constructed of. Staff stated it would a tan slumpstone material with a cap. Committee Member Bobbin asked if any plant material would be on the wall.. Mr. Lopez stated no. 4. Committee Member Thoms stated the landscaping at the corner of Fred Waring Drive and Jefferson Street, should be more of an opportunity to use the plant forms as a design element. It appears to be a scattered grove of palms. Behind there is a grove of citrus in a staggered form and then a lawn and border that does not reflect any kind of design element. The corner may look nice as a landscaped area, but does not make a landscape design statement. These are prominent corners in the City and should make a design statement versus just being a streetscape. He G:\WPDOCS\ARLC\2-5-03.wpd 2 '", 021 Architectural & Landscape Review Committee Minutes February 5, 2003 asked if the turf was flat or contoured, etc. Mr. Lopez stated he was questioning himself whether to do a design that was formal or informal and decided to mix the two. 5. Committee Member Cunningham commented that the plans need to be looked at from a maintenance point as well. 'The widening of Jefferson Street, development of the other corners, and the effects of that will all play into the picture. The opposite side of the street is the City of Indio and will be spruced up as the sites develop. The grass area could have great potential utilizing plants, but will be the easiest to maintain as the area and street develops. It does need to be tightened up and become more cohesive in the design by adding the palms. This design does resemble the PGA West entrance. He would keep the grass and bring more uniformity to the dates. Mr. Lopez suggested they come back with an alternative design for the corner landscaping only. 6. Committee Member Bobbitt suggested he take some alternatives to the Planning Commission for their review. Staff stated the applicant was directed to not address the corner as it is an area the City Council may want to address as an entry statement. In regard to the maintenance, it may become a part of a lighting and landscaping district at some point in time. 7. Committee Member Thorns stated unless some other body in the City has designed what will be placed at this corner, it should be addressed at this time. The whole corner should be rearranged with the plant materials to create a land form. It needs to be a visual statement. 8. Planning Manager Oscar Orci informed the Committee that staff was working with the developer of the corner to the south to also create an entrance statement for the corner. 9. There being no further discussion, it was moved and seconded by Committee Members Thoms/Cunningham to adopt Minute Motion 2003-004, approving Site Development Permit 2002-752, as amended. a. The landscaping at the northwest corner of Jefferson Street and Fred Waring Drive shall be developed and reviewed and redesigned to become more of a design statement for the short term and long term.

The City of La Quinta is proposing to amend the water efficient landscaping regulations for newly installed and rehabilitated landscapes to coincide with the recently adopted Coachella Valley Water District (CVWD) regulations. The purpose of the amended ordinance is to create and maintain lush and efficient landscapes. A landscaping documentation package consisting of a landscape design plan, irrigation plan, grading design plan, soils analysis and water calculations will be required to approve landscapes. These regulations will augment the City's existing landscape regulations. Draft regulations are attached (Attachment 1). Staff will also provide the public with a suggested landscape pallette consisting of various types of Vow and moderate water use vegetation (e.g. shrubs, palms, ivy, etc.). Attached (Attachment 2) are various species of plant material, as suggested by CVWD, please review them and provide staff with input regarding their appropriateness. In previous meetings the Architectural and Landscape Review Committee has expressed a desire to amend the codes and require larger tree wells. Staff proposes to amend the La Quinta Municipal Code Section 9.100.040 (B)(Attachment 3) and require a minium eight foot by eight foot tree well for all non-residential landscaping projects proposing such improvements. Staff recommends adoption of a minute motion recommending the suggested code amendments.

A. The purpose of this ordinance is to establish effective water efficient landscape requirements for newly installed and rehabilitated landscapes. It is also the intent of this ordinance to implement the requirements of the State of California Water Conservation in Landscaping Act, Statutes of 1990, Chapter 1145 (AB 325). B. It is the intent of the city council to promote water conservation through climate appropriate plant material and efficient irrigation as well as to create a city landscape theme through enhancing and improving the physical and natural environment. 0.00.020 Definitions. The words used in this chapter have the meanings set forth below: A. "Anti -drain valve" or "check valve" means a valve located under a sprinkler head to hold water in the system so it minimizes drainage from the lower elevation sprinkler heads. B. "Application rate" means the depth of water applied to a given area, usually measured in inches per hour. Also known as precipitation rate (sprinklers) or emission rate(drippers/microsprayers) in gallons per hour. C. "Applied water" means the portion of water supplied by the irrigation system to the landscape. D. "Automatic; controller" means a mechanical or solid-state timer, capable of operating valve stations to set the days and length of time of a water application. E. `Backflow prevention device" means a safety device used to prevent pollution or contamination of the water supply due to the reverse flow of water from the irrigation system. F. "Conversion faction (0.62)" means a number that converts the maximum applied water allowance from acre -inches per acre per year to gallons per square foot per year. The conversion factor is calculated as follows: (325,851 gallons/43,560 square feet)/12 inches = (0.62) 325,851 gallons = one acre-foot 43,560 square feet = one acre 12 inches = one foot To convert gallons per year to 100 cubic feet per year, the common billing unit for water, divide gallons per year by 748. (748 gallons = 100 cubic feet) G. "Ecological restoration project' means a project where the site is intentionally altered to establish a defined, indigenous, historic ecosystem. H. "Effective precipitation" or `usable rainfall' means the portion of total natural precipitation that is used by the plants. Precipitation is not a reliable source of water in the desert. I. "Emitter" means drip irrigation fittings that deliver water slowly from the system to the soil. J. "Established landscape" means the point at which plants in the landscape have developed roots into the soil adjacent to the root ball. .6.uu.032 8.13.030 K. "Establishment period" means the first year after installing the plant in the landscape. L.

The estimated annual applied water use shall not exceed the maximum applied water allowance. M. "Estimated total water use" means the annual total amount of water estimated to be needed to keep the plants in the landscaped area healthy. It is based upon such factors as the local evapotranspiration rate, the size of the landscaped area, the types of plants, and the efficiency of the irrigation system. N. "ET adjustment factor" means a factor of 0.6 that, when applied to reference evapotranspiration, adjusts for plant factors and irrigation efficiency, two major influences upon the amount of water that needs to be applied to the landscape. A combined plant mix with a site -wide average 0.45 is the basis of the plant factor portion of this calculation. The irrigation efficiency for purposes of the ET adjustment factor is 0.75. Therefore, the ET adjustment factor (0.6) _ (0.45/0.75). O. "Evapotranspiration" means the quantity of water evaporated from adjacent soil surfaces and transpired by plants during a specific time. P. "Flow rate" means the rate at which water flows through pipes and valves (gallons per minute or cubic feet per second). Q. "Hydrozone" means a portion of the landscaped area having plants with similar water needs that are served by a valve or set of valves with the same schedule. A hydrozone may be irrigated or nonirrigated. For example, a naturalized area planted with native vegetation that will not need supplemental irrigation once established is a nonirrigated hydrozone. R. "Infiltration rate" means the rate of water entry into the soil expressed as a depth of water per unit of time (inches per hour). S. "Irrigation efficiency" means the measurement of the amount of water beneficially used divided by the amount of water applied. Irrigation efficiency is derived from measurements and estimates of irrigation system characteristics and management practices. The minimum irrigation efficiency for purposes of this chapter is 0.75. Greater irrigation efficiency can be expected from well -designed and maintained systems. T. "Landscape irrigation audit" means a process to perform site inspections, evaluate irrigation systems, and develop efficient irrigation schedules. U.

"Service lane" means the pressurized pipeline that delivers water from the water source to the water meter. Y. "Maximum applied water allowance" means for design purposes, the upper limit of annual applied water for the established landscaped area. It is based upon the area's reference evapotranspiration, the ET adjustment factor, and the size of the landscaped area. The estimated applied water use shall not exceed the maximum applied water allowance. Z. "Mined -land reclamation projects" means any surface mining operation with a reclamation plan approved in accordance with the Surface Mining and Reclamation Act of 1975. j"OU; 033 8.13.030 AA.

BB. "Operating pressure" means the manufacturer's recommended pressure at which a system of sprinklers, bubblers, drippers or microsprayers is designed to operate. CC "Overhead sprinkler irrigation systems" means those with high flow rates (pop -ups, impulse sprinklers, rotors, etc.). DD. "Overspray" means the water which is delivered beyond the landscaped area, wetting pavements, walks, structures, or other nonlandscaped areas. EE. "Plant factor" means a factor that when multiplied by reference evapotranspiration, estimates the amount of water used by plants. For purposes of this ordinance, the average plant factor of very low water using plants ranges from 0.01 to 0.10, for low water using plants the range is 0.10 to 0.35, for moderate water using plants the range is 0.35 to 0.60 and for high water using plants, the range is 0.60 to 0.90. FF. "Rain sensing device" means a system which automatically shuts off the irrigation system when it rains. GG. "Record drawing" or "as-builts" means a set of reproducible drawings which show significant changes in the work made during construction which are usually based on drawings marked up in the field and other data furnished by the contractor. HH. "Recreational area" means areas of active play or recreation such as sports fields, school yards, picnic grounds, or other areas with intense foot traffic. Il. "Recycled water," "reclaimed water" or "treated sewage effluent water" means treated or recycled waste water of a quality suitable for nonpotable uses such as landscape irrigation; not intended for human consumption. JJ. "Reference evapotranspiration" or "ETo" means a standard measurement of environmental parameters which affect the water use of plants. ETo is given in inches per day, month, or year, and is an estimate of the evapotranspiration of a large field of cool -season grass that is well watered. Reference evapotranspiration is used as a basis of determining the maximum applied water allowances so that regional differences in climate can be accommodated. For purposes of this ordinance, the following ETo zone map will be used(See attached). KK. "Rehabilitated landscape" means any relandscaping project whose choice of new plant material and/or new irrigation system components is such that the calculation of the site's estimated water use will be significantly changed. The new estimated water use calculation must not exceed the maximum applied water allowance calculated for the site using a 0.6 ET adjustment factor. LL. "Runoff' means water which is not absorbed by the soil or landscape to which it is applied and flows from the planted area. For example, runoff may result from water that is applied at too great a rate (application rate exceeds infiltration rate), when there is a severe slope or when water is misapplied to hardscapes. MM. "Soil moisture sensing device" means a device that measures the amount of water in the soil. NN. "Soil texture" means the classification of soil based on the percentage of sand, silt and clay in the soil. 00. "Sprinkler head" means a device which sprays water through a nozzle. PP. "Static water pressure" means the pipeline pressure when water is not flowing. QQ. "Station" means an area served by one valve or by a set of valves that operates simultaneously. RR. "Turf' means a surface layer of earth containing mowed grass with its roots. Perennial and Annual Ryegrass are cool season grasses. Hybrid and common Bermuda grass, are warm season grasses. SS. "Valve" means a device used to control the flow of water in the irrigation system. TT. "Water Conservation Concept Statement" means a one -page checklist and a narrative summary of the project. .`.0P 034 8.13.030 UU. "Water Feature" means any water applied to the landscape for non -irrigation decorative purposes. Fountains, streams, ponds and lakes are considered water features. Water features use more water than efficiently irrigated turfgrass and are assigned a plant factor value of 1.1 for a stationary body of water and 1.2 for a moving body of water. W. "Recreational Turfgrass" means turfgrass that serves as a playing surface for sports and recreational activities. Athletic fields, golf courses, parks and school playgrounds are all examples of areas hosting recreational turfgrass. WW. "Recreational Turfgrass ET adjustment factor" means a factor of 0.82 that, when applied to reference evapotranspiration, adjusts for the additional stress of high traffic on recreational turfgrass and the higher irrigation efficiencies of long range rotary sprinklers. These are the two major influences upon the amount of water that needs to be applied to a recreational landscape. A mixed cool/warm season turfgrass with a seasonal average of 0.7 is the basis of the plant factor portion of this calculation. The irrigation efficiency of long range sprinklers for purposes of the ET adjustment factor is 0.85. Therefore, the ET adjustment factor is 0.82 = 0.7/0.85. Note: Section 65594, Government Code.

Date: Prepared by: .6.OU. 037 8.13.030 1. The Annual Maximum Applied Water Allowance. a. A project's annual maximum applied water allowance shall be calculated using the following formula: MAWA == (ETo) (0.6) (LA) (0.62) where MAWA == Maximum applied water allowance (gallons per year) ETo == Reference evapotranspiration (ie 75.0 inches per year) 0.6 = ET adjustment factor LA == Landscaped area (square feet) 0.62 == Conversion factor (to gallons per square foot) b. An example calculation of the annual maximum applied water allowance is: Project site: Landscape area of fifty thousand square feet in Zone #3a of the Coachella Valley ETo Map. MAWA =_ (ETo) (.6) (LA) (.62) (75.0 inches) (.6) (50,000 square feet) (.62) Maximum applied water allowance = 1,395,000 gallons per year, 1,865 hundred -cubic -feet per year(billing units), 4.28 Acre Feet/Acre per year or 51.4" of water per year. 2. Estimated Annual Applied Water Use. a. The annual estimated applied water use shall not exceed the annual maximum applied water allowance. b. A calculation of the estimated annual applied water use shall be submitted with the landscape documentation package. c. The estimated annual total water use for each hydrozone is calculated from the following formula: EWU (hydrozones) = (ETo) (PF) (HA) (.62)/748 (in 100 cubic feet) (IE) EWU (hydrozone) = Estimated water use (gallons per year) ETo = Reference evapotranspiration (ie. ETo Zone 3a = 75.00 inches per year) PF = Plant factor (see definitions) HA = Hydrozone area (square feet) (.62) = Conversion factor (IE) = Irrigation efficiency (see definitions) 748 = Conversion to billing units (100 cubic feet) 3. Estimated Annual Total Water Use. A calculation of the estimated annual total hydrozone water use shall be submitted with the landscape documentation package. The estimated annual total water use for the entire landscaped area equals the sum of the estimated annual water use (EWU) of all hydrozones in that :landscaped area. '1 % 03$ 8.13.030 4.

Arrange colors to please the eye and complement wall colors, interior color arrangements and surrounding plant material. Red, orange, and yellow are warm exciting colors. Blue, green, and violet are cool, calm colors. White can be used freely in masses, in borders or as guide lines along walks and drives. For quiet restful effects use gray -green, gray -blue, soft mauve, dull violet, and dusty pink. To prepare for successful planting: premoisten planting area to 12 inches, add organic soil additives and turn under 4 to 6 inches several weeks before planting (ignore this step for desert natives), provide for adequate irrigation coverage and evel and prepare for seeding or setting out transplants. Planting at the right season can make a difference in results. Most ideal planting temperatures for planting winter and spring annuals are when night air temperatures range between 400 F to 60' F, daytime air temperatures are in the 600 F to 800 F range, and when daytime upper soil temperatures are in the 500 F area. This ideal window generally occurs from mid --October through November. If new plantings are stressed clue to excess wind or sudden heat, you can reduce the shock by using starter solutions or vitamin Bt. In fast draining sandy soil, adequate moisture must be maintained continually to provide a favorable root climate. Neglect will cause hardening of tissues. Annuals and perennials compliment each other and create even more colorful combinations. Culturally, their needs are similar except, once established, the perennial generally uses less water. Most annuals are overwatered. If fungus is a problem, use a fungicide, Subdue 2--C or Cleary 3-3-36, before planting. Water Mizers: Eric & Dave's picks for water efficient landscaping !!

To perpetuate the beauty of wildflowers in the garden, follow some simple seed planting rules. Fall, winter and early spring are natural seeding periods for spring blooming species. Surnmer flowering varieties can be planted during the spring. Use '4JA, 056 http://www.cvwd.org/lush&eff/lsh&ef34.htm 5/30/2003 Wildflowers need ample sun Page 2 of 3 areas where there is ample sun. Prepare soil by thoroughly wetting the area 12 inches deep. Remove weeds and debris prior to cultivation. Apply weed free organic mulch and cultivate soil at least 3 to 6 inches in several directions. Rake lightly to create a seed bed. Broadcast seed by hand or with a small hand held fertilizer spreader. Most wildflower seed is very small so mix with fine dry sand to get more even distribution. After seeding, rake soil! lightly in a cross pattern to cover seed and water lightly. Avoid washing soil. Keep planted areas moist until sprouts appear. After sprouting, space watering to every 7 to 14 days depending on soil. Pull weeds as they appear. After plants have gone to seed, cut to 4--6 inches high and remove debris. Some fallen seed will have been eaten by birds so to insure another spring season of color, reseed with half as much in the fall. Spring seeding for summer annuals usually requires additional moisture. Perennial species will usually continue into the following year. Do not overwater. Select a seed mix to match your climate, elevation and moisture availability. Wildflower mixes are available for desert gardens. Sow seed in mild winter areas in the fall, and in the early spring where winters are severe. Seed mixtures should contain six or more species to ensure a long season of color. A one ounce seed packet will cover approximately 500 square feet. Fertilization is seldom necessary. Best results with wildflowers are generally achieved in soils of low fertility and lack of it helps to reduce weed growth that would be stimulated by cultivation in soil preparation. Any large or small garden area in a sunny location is a candidate for wildflowers. Varieties native to the desert are, by nature, better equipped to cope with your landscape needs than many water demanding species. The natural garden provides the home gardener more time to pursue other interests and activities. Germination periods vary considerably for different wildflower seeds. Some may sprout in two weeks, others may take four to six weeks. Adequate deep moisture is essential. A firm, well prepared seed bed plus moisture and shallow 1/8 inch depth for seed coverage provides the ideal growing conditions. Temperatures 30 degrees or colder often delay rapid germination.

During warm months, water regularly and fertilize monthly with an organic fertilizer. In slow draining soils, such as caliche clay, it is advisable to place a one or two foot layer of silt --free sand in the planting hole before placing the root ball to help provide drainage. Transplant palms during the warm months. Tie fronds together for at least a month after transplanting to prevent crown from drying. Use Vitamin B1 solutions after transplanting to reduce shock. Removing excess fronds only stimulates increase in height too rapidly and creates an undesirable tapered paint brush effect, especially on the tall species. See pruning rules help health & looks.

Soil preparation with organic mulches is an important ingredient. Installation of some type of irrigation system is essential. In other words, perennial gardening cannot be treated casually, but rewards are tremendous. The design of perennial beds can be rectangular, round or just complimentary to shrub plantings or they can give a sense of movement as they draw your eye from clump to clump in flowering curved flower beds. Interplant with seasonal annuals to fill flowing gaps. Free flowing lines and clusters of plants arranged to be viewed from different angles need to be created with low -growing flowers in the foreground, medium -height in the middle foreground and tall flowers as a backdrop. Perennials that require shade can be interplanted among large growing shrubs, in the mini -oasis patio or under dappled tree shade.
