19.105.010 Parking and loading requirements.
(A) Purpose. The purpose of this section is to alleviate or prevent congestion of the public streets, and to promote the safety and welfare of the public, by establishing minimum requirements for the off-street parking of motor vehicles in accordance with the use to which the property is put. It is the further purpose of this section to place upon the property owner the primary responsibility for relieving public streets of the burden of on-street parking.
(B) General Regulations.
(1) Size. A parking space shall mean an area of not less than one hundred sixty-six and one-half (166-1/2) square feet, with a minimum width of nine (9) feet, and a minimum depth of eighteen and one-half (18-1/2) feet, which is specifically designated for, and used for, the parking of an automobile or light truck, exclusive of all driveways and accessways.
(2) Permits. An applicant for plan review, development review, or a building permit must submit plans showing the off-street parking required by this section. These plans must show locations, arrangement, and dimensions of the off-street parking, turning spaces, drives, aisles, and ingress and egress, and must be approved by the zoning director. Whenever a permit has been issued in compliance with the requirements of this section, subsequent use of the structure or use of the land is conditioned upon the unqualified availability of off-street parking as shown in the approved plans.
(3) Alterations, Additions, and Expansion of a Business.
(a) A new use, addition, or alteration of a building shall not be approved if it would create or increase a deficit in off-street parking.
(b) It is unlawful to reduce the amount of existing parking below the minimum required by this section without first supplying other spaces as are required.
(c) If a building or business is destroyed, and if it is allowed to be reconstructed subject to the provisions of Chapter 19.95, it shall be required to provide only the number of parking spaces which existed prior to the destruction.
(d) If a business expands, it shall, in addition to the parking spaces in existence prior to such expansion, be required to provide only the number of additional parking spaces necessitated by the expansion.
(4) Parking Garage. All garage or other space allocated for the parking of vehicles, within buildings, basements, or on roofs of buildings, shall be considered part of the off-street parking facilities and may be included as such in computing the parking area requirements.
(5) Access. All off-street parking shall have access from a public street or alley.
(6) Ingress, egress, internal traffic circulation, off-street parking and loading facilities, and pedestrian ways shall be designed so as to promote safety and convenience and so that traffic visibility is not obstructed.
(7) Downtown Commercial Zone. There shall be no minimum parking space requirements for the Downtown Commercial zone.
(C) Design and Location of Parking Spaces.
(1) Single-Family Residences, Manufactured Homes, Duplexes, and Agricultural Uses.
(a) Location. Required off-street parking shall be located on the same lot or parcel as the use it is intended to serve.
(b) Surfacing. Off-street parking spaces, driveways, and accessways shall be properly surfaced and graded to prevent impoundment of surface water in a manner satisfactory to the city engineer.
(2) All Other Uses.
(a) Location. Required off-street parking shall be located within three hundred (300) feet of the building or use it is intended to serve, the distance being measured along the street line from the nearest point of the building or use to the nearest point of the parking lot. Whenever the use of a separate lot or parcel is proposed for fulfillment of minimum parking requirements, the owner shall submit as a part of his application satisfactory assurance that the separate lot or parcel is permanently committed to parking use by enforceable legal measure.
(b) Off-street parking spaces shall be situated in a manner which will not result in automobiles backing onto a public street.
(c) Surfacing – Customer, Patron Parking Areas, and Automotive Display Areas. All new construction shall be subject to the following: All areas, access ways, driveways, and display areas for vehicles with gross vehicle weight of less than two and one-half (2-1/2) tons shall provide a pavement design drawing showing the extent of the new pavement area. This design drawing shall include a section specifying the type and thickness of the asphalt pavement, aggregate base, and subgrade and shall consist of a minimum of three (3) inches of asphalt over an eight (8) inch aggregate base over a compacted subgrade, or as otherwise specified by the site design engineer and approved by the city engineer. Paved parking lots shall be maintained at an approved standard for paving. Existing gravel parking lots shall be maintained at an approved standard with a compacted aggregate base and surfaced with three-quarter-inch (3/4) minus gravel (cinders prohibited) at a two (2) inch minimum depth, or a material of equal or better strength and durability which meets the city engineer’s minimum standards. All surface water run-off shall be detained on-site or drained into a drainage system approved by the city engineer, and shall be maintained by the property owner. The city engineer may require a drainage study at their discretion.
(d) Curbing. A six (6) inch wide by six (6) inch high curb or bumper guard shall be installed along all property lines bordering the parking and maneuvering area, excluding necessary points of ingress and egress, and shall be so located that no part of a vehicle shall extend over or beyond any property line.
(e) Design. As indicated in the diagram below, all areas of the parking lot, with the exception of necessary points of ingress and egress, shall be no closer than ten (10) feet from the front property line. That unoccupied area shall be landscaped and maintained with trees, shrubs, ground cover, pedestrian walkways, and plazas in a manner acceptable to the zoning director. Such landscaping shall be maintained and kept in a weed-free manner. Access to off-street parking areas from a public street shall be from a two-way driveway with a minimum width of twenty (20) feet and a maximum width of forty (40) feet, or two (2) one-way driveways each with a minimum width of twelve (12) feet and a maximum width of eighteen (18) feet.
