19.05.020 Parking requirements.

A. The following parking requirements apply to all uses in the P zone.

B. General Requirements.

1. Surfacing and Grading. All off-street parking areas shall be graded and surfaced to a standard comparable to the street which serves the parking area. The parking area shall be developed and completed to the required standards before an occupancy permit for the building to be served is issued.

2. Traffic Control Devices. All traffic control devices such as parking strips designating car stalls, directional arrows or signs, bull rails, curbs and other structures shall be installed and completed as shown on the approved plans. Hard surfaced parking areas shall use paint or similar devices to delineate parking stalls and directional arrows.

3. Design. Parking lot design should conform to the diagrams set out in Appendix A of this development code, unless alternative design standards are approved by the design commission and city engineer.

4. Location. Off-street parking shall be located on the same lot or on an adjoining lot or lots to the building to be served; except, that off-street parking may be located in an area beginning within 500 feet of the front entrance of the building to be served; provided, that there are no intersecting streets between the parking area and building to be served. This requirement does not apply to transit facilities.

5. Ingress and Egress. The city engineer shall have the authority to fix the location and width of vehicular ingress or egress to and from property, and to alter existing ingress and egress as may be required to control street traffic in the interest of public safety and general welfare.

6. Handicapped Standards. Off-street parking shall meet the relevant state design standards for the physically disabled.

7. Compact Vehicles. Up to 50 percent of the required off-street parking spaces may be designed for accommodating compact vehicles. Such parking spaces must be clearly designated as compact stalls. The design commission may increase the percentage of compact stalls permitted if the applicant can demonstrate that no adverse impacts will occur.

8. Loading Space. An off-street loading space, having access to a public street, shall be required adjacent to each building hereafter erected or enlarged. Such loading space shall be of adequate size to accommodate the maximum number and size of vehicles simultaneously loaded or unloaded, in connection with the business or businesses conducted in such building. No part of the truck or van using the loading space may project into the public right-of-way.

9. Variances. Notwithstanding any of the minimum parking requirements set out in subsection C of this section, the code official may grant variances from the minimum parking requirements with the approval of the design commission and the city engineer for projects reviewable by the design commission.

C. Minimum Parking Requirements for Specific Uses.

1. Government buildings shall provide one parking space per 200 square feet of gross floor area.

2. Public schools shall provide one parking space per classroom with high schools providing an additional one parking space per 10 students.

D. Mixed Use Parking. In the case of mixed uses, the total requirements for off-street parking facilities shall be the sum of the requirements for the various uses computed separately. Off-street parking facilities for one use shall not be considered as providing required parking facilities for any other use, except as hereinafter specified for cooperative use.

E. Cooperative Parking. Cooperative parking between two or more adjoining property owners is allowed; provided, the code official, with approval from the design commission and city engineer, may reduce the total required spaces by 25 percent of the total combined required spaces when the applicant has demonstrated that no adverse impact will occur due to the reduced number of stalls.

F. Parking Lot Dimension. All parking areas shall conform to the design standards set out in Appendix A of this development code unless alternative design standards are approved by the design commission and city engineer. (Ord. 99C-13 § 1).
