ADOPTED this ]9th day of N0vember , 1990--. ATTEST: ~-~nlce C. Guy ~ Clerk of the Coun~l COUNCILMEMBERS: Mayor Young Aye APPROVED AS TO FORM: Acosta A.ye ~e Griset A.ye May Aye McGuigan A.¥e r Norton A.ye City Attorney Pulido A,ye EXHIBIT A DESIGN AND DEVELOPMENT STANDARDS FOR PARKING STRUCTURES 007' DEFINITION: A parking structure is a facility exclusive of surface parking lots whose primary use is the temporary parking of motor vehicles. I. Exterior/Architecture Exterior walls of parking structures shall be finished with the same material to match the architectural character of the principal building. Architectural character Js defined as the composite or aggregate characteristics of a structure, including but mot limited to form, materials, architectural details and other characteristics. 2o The exterior of the parking structure shall be harmonious to the surrounding buildings in the area as well as the principal building(s) it serves. Retail use at the ground level of the parking structure is encouraged in general to provide a transitionary component and to improve the architectural character. Exterior elevations shall be designed to minimize untreated facades. Untreated facades lack interesting patterns and/or variation in surfaces. Blank facades on walls shall be limited to a maximum of 20' horizontally. Exterior elevations shall replicate the window pattern and other architectural elements of adjacent buildings. An active streetscape shall be created through the use of water walls, sculptures, two or more complementary building materials and facades at ground level. Pipes, mechanical equipment, etc., shall not be permitted on any exterior surface and shall be screened from public view by incorporating them into the structure. They shall not be viewable from public areas. Exterior walls of the parking structures shall have an open air design with the first floor (ground level) walls being a maximum of three feet high (except for sheer panels). A decorative grill work shall be placed between such a wall and the flooring for the second parking level (Figure 1). The extarior elevations of the parking structure are encouraged to exhibit horizontal rather than sloping design elements. 10. $1gnage and graphics for the parking structure shall be consistent, harmonious and visually related through the incorporation of common design elements. Exterior sfgnage shall -1- 008 II. be consistent and match the main buildlng's signage. These elements shall be incorporated into a planned sign program for the entire development site. 11. All interior components of the structure viewable by the public shall be painted in compatible colors to match the exterior of the structure. The sides of exterior columns and exterior walls that return to the interior shall match the exterior color(s). Interior Elevators shall be located where the door and open cab are visible to the public using the facility. The shaft and cab shall have glass backs. Any glass back tinting shall be minimal to allow maximum daytlme as well as nlghttime interior cab surveillance. Public and semi-private bathrooms are prohibited in the parking structure. Private bathrooms for the parking attendant shall be located where the doors are immediately adjacent to the parking attendant office or station and be visible to the attendant on duty. All solid stairwell doors shall be provided with viewing panels. Blind corners in stairwells shall be eliminated through the use of convex mirror. Garage stairwells at ground level shall be fully enclosed and designed to provide maximum interior visibility of the stairwell. The enclosure must be equipped with a control in/free out form of access control. III. Circulation Entrances and exits shall be designed and located to minimize impacts on residential streets and busy intersections. The design of entrances and exits shall, minimize conflicts with pedestrian movements. Dead-end or "hammerhead" type parking is not an acceptable solution to parking circulation. Fully integrated parking and/or a turning radius are usable methods to achieve proper circulation. Elevator and stair shafts, mechanical rooms and similar visual disruptions located on the interior of parking levels shall be minimized. Pedestrian and vehicle vertical circulation elements shall be placed on the periphery of the floor area to obtain the maximum amount of level floor areas. Ail stairwells shall be of an open air design and stairs should be open to both the interior and exterior of the structure. -2- IV. e The number of pedestrian and w~hicular access points shall be minimized. A minimum of 4' w~de pedestrian sidewalks along side every vehicular access locati~u(s) shall be provided. Ail entrances and exits should be capable of closure after hours. Trash enclosures shall never be placed adjacent to points of pedestrian or vehicular access. Any trash enclosures located within the footprint of the parking structure shall be fully enclosed and lockable. Pedestrian routes from the parking structure lobby to the principal building shall provide an aesthetic transition compatible with the quality of the building. Pedestrian circulation shall be clearly delineated and separate from automobile circulation. The use of landscaping, walkways and decorative hardscape is encouraged to emphasize pedestrian areas. 10. Any subterranean levels shall use offset sloping rams to allow for open and unobstructed v~slbility for floor surveillance. 11. Horizontal beam type construction shall be used to eliminate column supports in parking spaces and aisle areas. Setbacks Parking structures above grade shall maintain the established setback for the area and all of the following applicable setbacks, whichever is greater: a) Setbacks per appropriate zone; however, the minimum setback for corner lots shall be 25' on the street sides of the structure. b) Building up to 25' in height shall provide a minimum 15' street setback; building above 25' shall provide an additional 5' setback at each level above the 25' base. c) Setbacks for side yards and rear yards shall be a minimum of 10' wide. 2. Structures that abut property zoned, used or designated on the General Plan for residential purposes shall provide a 15' minimum buffer area adjacent to that use. Ail setbacks shall be landscaped. Berms and slopes may be used to give more dimension to the setback. Ail appurtenances (i.e. transformers, ventilation shafts, etc.) must be located outside any required setback and shall be screened from public vlew. 5. Structures with staggered setbacks shall provide landscape planters at each level suffic~ent width and depth to support shurbs, grouadcovers, and vines. A shade and shadow study shall be completed for any parking structure adjacent to residential, commercial or professional office uses to determine what Impact the parking structure may have on the adjacent use. The shadow of the proposed structure must not fall onto the adjacent property as defined above during the hours from 10:00 A.M. to 2:00 P.M. on any given day. 7. No parking area above or below grade shall be allowed to encroach into any required minimum setback. Landscaping The required landscaping shall be located adjacent to the structure and be distributed around its perimeter. ~ere the landscaping is adjacent to ventilation openings, shrubs must be maintained at a height of no greater than 3 feet. Trees placed in front of ventilation openings must be trimmed up to a height of six feet (Figure 1). A plaza/courtyard area shall be provided between the parking structure and principal building. A minimum of 50% of this area shall be landscaped, exclusive of decorative hardscape. Water features, such as fountains, water walls and pools shall be considered as part of the landscape. 3. The area of the plaza/courtyard shall be determined by the square footage equal to ten (10) times the base perimeter of any parking structure that has two parking levels of less. A landscape area equal to five times the perimeter of the parking structure shall be provided for each additional level of parking. The minimum width of the plaza/courtyard shall be 50% of the parking structure footprint and measured adjacent to the plaza/courtyard. 4. Lan~cape planters slia~ '~/e~ pr~v~ded~t every ot~g level of the structure and be a minimum of 50~ perimeter of that level. Minimum planter dimens_~.~l have dimensions equal or greater than a~.~th and 4' depth. An internal drainage system an~ proofing of the planters shall be provided~~ with a drip~igatton system. A proper ' enter mix shall be specified on the landscape plan. A trellis work may be incorporared into the building design where blank walls occur on the structure. The trellis material shall be constructed of decorative and durable materials to enable vines to attach themselves for support. The trellis area must cover up to a minimum of 60% of the blank wall. Water conservation shall be an important consideration when selecting a plant palette. Plant materials shall be of California origin or from sub-tropical or Mediterranean type climates similar to that the Southern California. An automatic irrigation system shall be designed to provide deep watering for trees, shrubs and vines along with moisture sensors to monitor and minimize water usage. -4- A minimum quantity of plant material shsll be provided based upon the number of parking spaces in the structure. For each 100 parking spaces, the following minimum quantities shall be provided: TREES Container Size Quantity 48" box 1 36" box 3 24" box 5 NOTE: SHRUB Palm trees may be substituted up to 20% of the total tree required. Minimum brown trunk shall be 12 feet Container Size Quantity 5 gallon size 48 HERBACEOUS PERENNIALS VINES Equal number of 1 and 5 gallon Container Size 5 gallon size 48 Quantity/Spacing One vine per 12-15' on center for trellis areas; 20' on center as foundation plantings NOTE: GROUND COVER Vines are considered as part of Container Size Well rooted in flats and top dressed with organic mulch material the shrub requirement ~uantit¥/Spacing 6-12" apart in a triangular pattern depending upon plant species TURF Type Drought tolerant frescue culttvars, sod or hydroseed Quantity 30% maximum of the planting area 0il -5- 012 8. Reverse slopes shall have the same requirements as ground level plantings except tha~ the slope shall not exceed a 3:1 grade. All slopes sh~ll be provided with a slope retention jute type material (or equal) amd be anchored securely to the slope. A special drsJnage system shall be provided to remove surface water for reverse slopes. A concrete retaining wall shall be provided ~or slopes greater than one level of subterranean parking. 9. water features, suca as s' w en~curagad In plaza areas. -6- 0,.3 HEDGE MATERIAL SCALE: 3/8'- 1' FIGURE 1 LANDSCAPE AND ARCHITECTURAL TREATMENT FOR GROUND FLOOR OF TYPICAL PARKING STRUCTURE -7-
