(D) Parking facility standards. In accordance with the landscaping provisions of this Code, planting zones shall be provided which utilize design and landscaping concepts within the area where vehicles are parked to enhance the visual attractiveness of the parking area and to reduce the amount of heat and other adverse conditions which occur in parking lots.
(E) Parking lots.
(1) For Districts zoned O, NC, or HC, all parking lots for ten or more cars shall provide for safe pedestrian access from car to destination, and vice versa. Parking lots shall be designed and constructed with origin-destination routes and sensible pedestrian pathways. Parking areas up to two parking bays (maximum of ten cars per bay) deep shall be located perpendicular to the final destination. If additional parking bay sets (up to two bays per set) are required, they shall be positioned at an angle (minimum of 20 degrees) to adjacent bays. Sidewalks shall be installed between parking bays.
(2) All parking lots for ten or more cars shall have sidewalks or planter strips to lead pedestrians from their cars to shopping or business areas. Sidewalks or planter strips shall be placed in front of all parking spaces.
(3) If sidewalks are provided, they shall be a minimum of five and one-half feet wide or meet minimum ADA requirements, whichever are more restrictive, and allow for auto overhang of 15 inches on each side. Parking bay sidewalks shall contain attractive bench or seating/resting areas (minimum of one bench or seating/resting area per 50 parking spaces). Bench or seating/resting areas shall contain shade trees or other vegetation meeting the city's landscape code. Bench/seating areas shall contain litter receptacles and shall be continuously maintained by the owner.
(4) In lieu of parking lot sidewalks, planter strips shall be provided as informal pedestrian walkways and to shade and screen cars. Planter strips shall be a minimum of five and one-half feet wide, shall be planted with trees meeting the landscape provisions of this Code, and shall contain bench or seating/resting areas (minimum of one bench or seating/resting area per 50 parking spaces).
(5) Parking lot sidewalks and planter strips shall be designed to integrate with lighting requirements to provide for pedestrian safety and visual appearance.
(F) Paving and drainage. The following basic standards shall be observed:
(1) In all districts, parking and loading facilities shall be surfaced and maintained with asphaltic, concrete, or other permanent hard surfacing material sufficient to prevent mud, dust, loose material, and other nuisances. Materials may be pervious.
(2) All parking and loading facilities shall be graded and provided with permanent storm drainage facilities, meeting the construction specifications set by the city. Surfacing, curbing, and drainage improvements shall be sufficient to preclude free flow of water onto adjacent properties or public streets, and to provide adequate drainage.
(G) Safety features. Parking and loading facilities shall meet the following standards:
(1) Safety barriers, protective bumpers or curbing, and directional markers shall be provided to assure safety, efficient utilization, protection to landscaping, and to prevent encroachment onto adjoining public or private property.
(2) Visibility of and between pedestrians, bicyclists, and motorists shall be assured when entering individual parking spaces, when circulating within a parking facility, and when entering and exiting a parking facility.
(3) Internal circulation patterns, and the location and traffic direction of all access drives, shall be designed and maintained in accord with accepted principles of traffic engineering and traffic safety.
(H) Lighting. Lights provided to illuminate any parking facility or paved area shall, to the maximum extent feasible, be designed to reflect away from any residential use. See Table B in § 150.105.
(I) Fencing and screening. A parking facility in any nonresidential district which adjoins or abuts property in a residential district shall have a wall or fence or vegetation screen not less than four feet in height located for the length of the common boundary.
(J) Noise. Areas used for primary circulation, for frequent idling of vehicle engines, or for loading activities shall be designed and located to minimize impacts on adjoining properties, including provisions for screening or sound baffling. See Table C following in § 150.105.
(K) Maintenance. All parking and loading facilities shall be maintained to assure desirability and usefulness of the facility. Such facilities shall be maintained free of refuse, debris, or other accumulated matter and shall at all times be available for the off-street parking or loading use for which they are required or intended.
(L) Adjustments. For a use or a site subject to site plan review or a special use permit, the minimum requirements of this section may be adjusted in their application, provided such change is determined by the Council to provide improved design, usability, attractiveness, and protection to adjoining uses, in a manner equal to or greater than the specific requirements of this section.
(M) Striping. Crosswalk lines shall be painted on the surface of the parking lot from handicapped parking areas to the building. Crosswalk lines shall be solid white lines, marking both edges of the crosswalk. They shall be not less than six inches in width and should be spaced less than six feet, but more than four feet apart. For added visibility, the area of the crosswalk may be marked with white diagonal lines at a forty-five degree angle or with white longitudinal lines at a ninety degree angle to the line of the crosswalk. These lines should be approximately 12 inches to 24 inches wide and spaced 12 inches to 24 inches apart. Warning signs should be installed to notify drivers that the crosswalk areas may be used by persons with disabilities.
