This Article describes the minimum design standards required for all at-grade surface vehicle parking areas. One- and two-family dwellings are exempt from these requirements.
A. 
Location. No vehicle parking spaces shall occupy any of the required setbacks unless the parking area is the only developed use of a legal lot of record and provided that all the other screening and landscaping requirements of this Title have been met. This requirement may be waived for the rear setback where alley access serves the subject property, provided the entire block length of the alley right-of-way is free and clear of any obstructions and adequately surfaced with an all weather material such as gravel, concrete, or asphalt. Parked vehicles shall not overhang property lines or walkways unless otherwise approved by the Director.
B. 
Surfacing. On site areas used for the parking and maneuvering of vehicles shall be surfaced with material approved by the City Engineer.
C. 
Striping. All parking spaces shall be striped.
D. 
Curb Cuts. Curb cuts shall meet the design requirements specified by the Americans with Disabilities Act, the City Engineer, and the placement requirements specified in Article 6.050: Access Management and design requirements specified in Article 6.060: Driveway and Entrance Standards.
A. 
General. Internal circulation shall be designed to facilitate movement of vehicles, bicycles and pedestrians in a safe and efficient manner, with a minimum of impervious surface coverage.
B. 
Emergency Vehicles. Safe and convenient vehicular access shall be provided for service and emergency vehicles.

A. 
General Provisions.
1. 
Motor vehicle parking lots, loading, and maneuvering areas shall be landscaped by medium and large canopied deciduous trees, mid-sized shrubs, and groundcovers to reduce the visual impact of glare, headlights, and parking lot lights from the public right-of-way and adjoining properties. The intent of a landscaped parking lot is also to break-up and screen the areas of impervious surfaces, reduce the level of carbon dioxide in areas of heavy vehicle use, return pure oxygen to the atmosphere, provide shade as a means of altering the microclimate, and generally improve the environmental and aesthetic qualities of the parking areas.
2. 
Efforts shall be made through the design and layout of parking area(s) to save as many existing trees on site as possible.
3. 
All required landscaped areas shall be irrigated with a permanent irrigation system.
4. 
The property owner is responsible for the establishment and continued maintenance of parking lot landscaping in accordance with the requirements of this Article.
5. 
The minimum planting size for trees shall be 2.5 inches caliper at 5 feet above grade per the requirements of Section 10.6.070.100: Measuring Tree Diameter.
6. 
Tree species shall be chosen from the recommended tree list provided by the Director; however trees must be deciduous and capable of reaching 30 feet in height and spread at maturity.
7. 
A minimum of 60% of all landscaped areas, including required planting strips and planting islands, shall be covered with trees, shrubs, and ground cover. The remaining 40% may be dry landscaped with approved materials.
8. 
Shrubs shall be at least 24 inches high at maturity and a minimum of one-gallon size at the time of planting.
B. 
Landscaping/Screening Along a Public Right-of-Way. All surface vehicle parking lots larger than 6 spaces, and all maneuvering and loading areas shall provide a minimum 5-foot wide screen buffer between the parking, maneuvering or loading areas and a public right-of-way (except alleys and accessways). The screen buffer shall also be required along interior lot lines in residential neighborhoods. Where the curb or the edge of these areas is used as the tire stop for parking, the screen buffer area shall be a minimum of 7.5 feet wide. The screen buffer area shall be landscaped according to the following requirements:
1. 
One of the following 2 types of buffering shall be provided (in addition to required street trees):
a. 
Planting Strip. A planting strip in the required buffer between the right-of-way and parking area. The planting strip may be pierced by pedestrian and vehicle accessways. Planting strips shall be planted with trees meeting the specie and size criteria of paragraphs (A)(5) and (A)(6) of this section, and a low level evergreen hedge no more than 48 inches in height.
b. 
Wall or Hedge. A decorative wall or evergreen hedge screen no more than 48 inches in height and established parallel to, and no nearer than 2 feet from, the right-of-way line. The area between the wall or hedge and the street/sidewalk line shall be landscaped. The wall or screening shall be designed to allow a free access to the site or sidewalk by pedestrians.
2. 
Visual Breaks. Visual breaks, not more than 5 feet wide, shall be provided every 30 feet within evergreen hedges abutting public rights-of-way.
3. 
Shrubs. Shrubs used for screening parking lot areas shall be planted in minimum 1 gallon container sizes, or larger, in order to achieve a desired height of 30 inches within 12 months.
C. 
Interior Parking Lot Landscaping. In addition to buffer landscaping along the public right-of-way (excluding alleys and accessways) and along interior lot lines where required, all surface parking lots greater than 6 spaces shall include landscaping to cover not less than 10% of the interior of the parking area in accordance with the following:
1. 
A planting bay shall be located at the end of each parking row and at intervals between parking rows. Planting bays shall be a minimum of 9 feet wide, to allow doors to open without damage, and a minimum of 180 square feet. Each bay shall be curbed, and planted with 1 approved tree having a clear trunk height of at least 9 feet when mature. Height of all plantings, other than trees, in planting bays is limited to 24 inches.
2. 
All trees shall be selected from the recommended tree list provided by the Director.
3. 
Trees shall not be placed within 10 feet of a public utility easement without prior approval of the City Engineer.
4. 
Parking areas shall be separated by a 5-foot landscaped planting bed from all exterior walls that include no pedestrian entranceways or loading areas.
