All off-street parking and loading facilities including entrances, exits, maneuvering areas, waiting areas, and parking and loading spaces shall be in accordance with the following standards and specifications.
(a) Parking Space Dimensions. Each off-street parking space, open or enclosed, shall measure at least nine (9) feet by twenty (20) feet. Compact parking spaces measuring at least seven feet six inches (7' 6") by sixteen (16) feet are permitted as regulated in 1161.107.
(b) Waiting Space Dimensions. Each off-street waiting space for a drive-thru or drive-in facility shall have an area not less than 160 square feet (measuring eight (8) feet by twenty (20) feet).
(c) Circulation Aisles. The maximum width for a two-way circulation aisle shall be twenty-four (24) feet and the minimum width for a circulation aisle shall be:
(1) Twenty-two (22) feet for 90 degrees or perpendicular parking;
(2) Eighteen (18) feet for 60 degrees parking;
(3) Thirteen (13) feet for 45 degrees parking.
(c1) Access drives. There shall be adequate provision for ingress and egress to all parking and loading spaces. Access drives shall be provided as follows:
(1) Each zoning lot shall be permitted one (1) entrance and one (1) exit per street frontage.
(2) The width of an access drive measured at the front lot line shall not be less than eleven (11) feet per lane nor greater than twelve (12) feet per lane and shall have a total width no greater than thirty-six (36) feet.
(3) An access drive shall be located no closer than ten (10) feet to a residential district and the resulting adjacent open area shall be properly landscaped and maintained in accordance with the standards in Section 1166.07.
(d) Paving. All required spaces, together with driveways, aprons, parking pads, other circulation aisles and access sidewalks, both public and private, shall be surfaced as follows:
(1) Parking lots and circulation aisles for parking lots: Concrete not less than six (6) inches in thickness, or with bituminous surface not less than three (3) inches in depth on top of a compacted crushed stone base not less than six (6) inches in depth. Paving with semi-pervious materials (e.g. permeable pavers, porous asphalt, porous concrete, grass-crete or gravel-crete) that are able to withstand vehicular traffic or other heavy-impact uses are permitted in accordance with Paragraph (4) below. Surfaces in areas designated as accessible parking and/or accessible pedestrian paths shall meet all applicable federal and state standards.
(2) Aprons: Concrete not less than six (6) inches in thickness for residential aprons and concrete not less than eight (8) inches in thickness for commercial aprons.
(3) Driveways: Concrete not less than four (4) inches in thickness, or with bituminous surface not less than four (4) inches thick consisting of two (2) inches of compacted #301 binder course and two (2) inches of compacted #404 surface course over a four (4) inch compacted aggregate base or paving with semi-pervious materials that are able to withstand vehicular traffic or other heavy-impact uses is permitted (e.g. permeable pavers, porous asphalt, porous concrete, grass-crete or gravel-crete).
(3a) Parking pads: Rear yard parking pads may be constructed of gravel subject to rear yard coverage and setback provisions and shall be designed and maintained to prevent displacement of gravel.
(4) Alternative paving materials: Semi-pervious materials, such as permeable pavers, porous asphalt, porous concrete, grass-crete or gravel-crete shall permit natural percolation of water and be installed and maintained in accordance with industry and manufacturer's standards and the following:
A. The manufacturer's specifications are applicable to the subject property's particular soil type and slope (gradient) so that vehicles are supported without rutting and water percolation is achieved.
B. Semi-pervious parking areas must allow storm water to percolate into the ground at a rate sufficient to accommodate the five-year, 24-hour storm event.
C. The City may inspect the semi-pervious parking areas as needed. If maintenance is required, the owner may be required to submit to the City documentation of the removal of visible surface sediment accumulations, and/or test results of infiltration rate through the pervious concrete and sub-grade soils system.
D. For non-residential uses, if only a portion of the parking area is designated for semi-pervious materials, the area designated for semi-pervious parking shall be located at the perimeter of the parking lot, and if possible, remote or furthest removed from the principal building.
(5) Sidewalks, both public and private: Concrete not less than four (4) inches in thickness, or an equivalent stone material. Sidewalks on private property may be constructed of alternative paving materials described in Section 1161.11(d)(4).
(e) Drainage. All required spaces, together with driveways and other circulation aisles, shall have adequate provision for underdrainage and for the disposal of storm water, so that water shall not flow onto adjoining property or adjacent sidewalks in a quantity or manner that would be detrimental thereto, or inconvenient to persons using the sidewalk.
(f) Curbs and Curb Inlets. A concrete or stone curb at least six (6) inches high shall be installed and maintained along the perimeter of a parking or loading area in accordance with the following:
(1) When abutting a landscaped area;
(2) When located in the front yard;
(3) When a commercial or public parking lot is located adjacent to a residential district.
(4) Curb inlets are required to allow water to flow into the landscape areas as permitted by site grading.
(g) Marking. The location of each parking space and the location and direction of movement along the driveways providing access thereto shall be indicated by painting upon the surface, by raised directional signs, or by markers or other similar measures placed in the surfacing.
(j) Lighting. Wherever a parking lot, open parking deck, or open private parking garage is to be used during darkness, a system of floodlighting shall be installed to provide an adequate standard of illumination over the entire parking lot. All floodlights shall be shielded so that a minimum glare will extend to adjacent property and shall be in compliance with Section 1165.07.
(k) Attendant's Shelter. A properly designed shelter for a parking lot attendant may be maintained on the lot and shall maintain the same distance from the right of way as the building on the adjacent parcels.
(l) Maintenance. A parking lot, open parking deck, or private parking garage shall be maintained in a manner to keep it as free as practicable from dust, paper and other loose particles, and snow and ice shall be promptly removed by the operator. All adjacent sidewalks shall be kept free from dirt, ice, sleet and snow and in a safe condition for use by pedestrians. All signs, markers or any other methods used to indicate direction of traffic movement and location of parking spaces shall be maintained in a neat and legible condition. Any walls, trees and shrubbery, as well as surfacing of the parking lot or garage, shall be maintained in good condition throughout its use for parking purposes. All exposed concrete walls shall be painted or finished.
