§ 59-10250 — Parking area construction standards

§ 59-10250. - Parking area construction standards.

10250.1. Parking Stall Design Standards. A. Basic Design Standards. The basic parking stall shall be eight and one-half feet in width and 18 feet in length. The following tables and diagrams establish minimum design standards for parking areas utilizing this minimum requirement, as well as dimensions to be followed if the optional parking stall size of nine feet in width and 18 feet in length is used. Nothing in these standards shall prohibit an owner/applicant from providing larger aisle widths or stall dimensions in excess of these minimum standards in order to better suit his/her development requirements. B. Alternate Design Standard. While tables provide design standards for angles of zero degrees, 45 degrees, 60 degrees, 75 degrees and 90 degrees, the Public Works Director shall be permitted to approve an alternate design using different angles, provided the property owner submits such a design with calculations for stalls and aisles based upon the standards contained herein. C. Small Car Parking Design Standard. Where a parking lot is required to contain 20 or more spaces, the Public Works Director shall be permitted to approve an alternate design for spaces to specifically accommodate compact automobiles. Said design shall conform to the following minimum basic standards. (1) Up to 15 percent of the required spaces may be allocated for compact cars. (2) Dimensions for a compact car space shall be seven and one-half feet in width and 15 feet in length. (3) Compact car spaces should be designed and striped at 90-degree angles or an equivalent, which will eliminate access and use by large cars. 10250.2. Paving. All off-street parking areas, aisles and access driveways and driveway approaches shall be permanently paved with hard-surfaced pavement. The requirement for a hard-surfaced driveway approach may be waived by the Director in areas not designated for urban development and in other areas if it is determined that the public convenience, health or safety is not affected. However, all portions of a driveway approach on public rights-of-way, connected to paved streets for which the grade has been established, must be permanently paved with hard-surfaced pavement and comply with all Oklahoma City Codes relating to driveway construction. Permanent hard-surfaced pavement shall mean a surface covering over earth, gravel or other natural or artificial base or foundation, which shall meet or exceed the following minimum standards: A. Two inches of hot asphaltic concrete on a four-inch base of stabilized aggregate or the equivalent thereto, which has been approved by the Director. B. Four inches of Portland cement concrete on a two-inch sand cushion base or the equivalent thereto, which has been approved by the Director. C. All portions of access driveways on public right-of-way require six inches of Portland cement concrete on a two-inch sand cushion or the equivalent thereto, which has been approved by the Director. D. Alternate pervious surface shall be allowed for the storage and maneuvering of vehicles, equipment and inventory, located within designated storage areas, accessory to the following use units: Horticulture (59-8150.7), Heavy Public Protection and Utility (59-8250.9), Automotive and Equipment: Sales and Rental, Farm and Heavy Equipment (59-8300.19), Construction Sales and Services (59-8300.31), Hazardous Industrial (59-8350.4), Industrial, Heavy (59-8350.6), Industrial, Moderate (59-8350.7), Industrial, Light (59-8350.8) and Wholesaling, Storage and Distribution: General (59-8350.15) provided: (1) Such alternate surface meets the following standards: (a) Traffic bound surface course by the Oklahoma Department of Transportation Standard Specifications Section 403 or; (b) Eight inches of cement kiln dust overlain with five inches of dust-free asphalt millings or; (c) Three to four inches of crusher run over one and one-half to two inches of gravel or; (d) Equivalent standard as approved by the Director, (2) Sub-base preparation is required in accordance with Oklahoma City Paving Construction Standards. (3) All pervious surface areas shall have a six-inch thick, 12-inch wide concrete border to keep the material in place. (4) The access driveway that extends into the site past the property line and all required parking shall be permanently paved with hard surfaced pavement provided for in Section 59-10250.2 (Paving). (5) All pervious surface fire lanes must be approved by the Fire Marshal's Office. 10250.3. Striping. A. Off-street parking areas shall be designed to provide systematic and orderly circulation, traffic separation devices, and parking spaces in accordance with this article, and with sound traffic engineering practices. B. All off-street parking spaces and means of ingress and egress shall be laid out on the parking surface with paint or plastic striping, which will provide a permanent delineation between spaces, aisles and surrounding structures and land. C. No striping shall be required for lots of single-family, two-family, three-family or four-family residential structures. 10250.4. Separation from Public Right-of-Way. All off-street parking areas, aisles and access driveways that abut public street rights-of-way shall be separated by a six-inch Portland cement concrete header curb, bumper or landscape timbers, except in the HL and HP Districts where landscape timbers are not allowed. Such curb, bumper or landscape timbers shall be designed so that vehicles do not overhang public rights-of-way or adjacent property. 10250.5. Lighting. All lighting equipment used in illumination of off-street parking areas shall not create a nuisance or hazard for streets or adjoining properties. Additional parking lot lighting regulations are found in Section 59-12350 (Site Lighting Requirements). 10250.6. Clearance. A. There shall be a minimum vertical clearance free of all obstructions to a height of eight feet for all portions of any off-street parking space, except when off-street parking spaces are provided in a parking structure, a residential garage or carport. No obstruction shall project into this minimum clearance. B. There shall be no obstruction within or near the bounds of any required off-street parking space that would interfere with the normal availability and use thereof. 10250.7. Aisle Standards. A. Aisles providing access, but not immediately adjacent or providing direct access, to an off-street parking space, shall be at least 22 feet in width if designed for two-way traffic and at least 12 feet in width if designed for one-way traffic. B. Aisles located immediately adjacent to buildings or structures shall be separated by a planted or landscaped strip, or a sidewalk of not less than three feet in width protected by a six-inch concrete curb, or, in lieu thereof, a bumper guard of a height not less than two feet above the finished grade. C. Parking may be located immediately adjacent to buildings or structures without a planted or landscaped strip, or a sidewalk, however, a bumper guard shall be located adjacent to such buildings or structures as specified in Paragraph B above. D. A drive-in window shall not project more than one foot into an aisle. 10250.8. Residential Parking Design and Regulation. A. Single-family, two-family, three-family and four-family residential structures located on one lot may use a paved driveway to fulfill the minimum parking requirements of this article. The space for each automobile on the paved area shall be a minimum of eight and one-half feet in width and 18 feet in length, and shall not be located within five feet of the street pavement. The residential driveway shall conform to the driveway design requirements as specified in this section. B. On lots less than one acre in size in the R-1, R-1ZL, R-2, R-3 and R-MH-1 Districts, and portions of PUD Districts with single-family, two-family, three-family or four-family residential uses, and on lots less than one acre in size with single-family, two-family, three-family or four-family residential uses located in non-residential zoning districts, vehicles shall be parked in the following manner: (1) Vehicles shall be parked on a permanently hard-surfaced (paved) driveway or parking area, meeting the design requirements specified in this section. A minimum of 25 percent of the lot shall be maintained as open space with no buildings or parking.

In addition, the gravel driveway shall be perpendicular to the street right-of-way, or parallel to the existing paved driveway; provided, that such enlargement made from and after the effective date of this ordinance shall meet the design requirements specified in this section. (3) However, any driveway that, as of October 1, 1988, did not meet the design requirements as specified in this section shall be deemed to be legally nonconforming for the purposes of this section. Vehicles may be parked on legally nonconforming driveways. The width of such driveways shall be determined by the width of the driveway throat at the property line, to a maximum of 12 feet. The legally nonconforming driveway shall be rectangular in shape and perpendicular to the property line. (4) This section addresses the proper parking of vehicles to protect neighborhood quality.
