18.90.030 General provisions – Off-street parking and loading.
A. The provision and maintenance of off-street parking and loading spaces is a continuing obligation of the property owner. No permit shall be issued until plans are presented that show property that is and will remain available for exclusive use as off-street parking and loading space. The subsequent use of property for which the permit is issued shall be conditional upon the unqualified continuance and availability of the amount of parking and loading space required by this title. Use of property in violation hereof shall be a violation of this title. Should the owner or occupant of a lot or building change the use to which the lot or building is put, thereby increasing off-street parking or loading requirements, it shall be unlawful and a violation of this title to begin or maintain such altered use until the required increase in off-street parking or loading is provided.
B. Requirements for types of buildings and uses not specifically listed herein shall be determined by the planning commission based upon the requirements of comparable uses listed.
C. In the event several uses occupy a single structure or parcel of land, total requirements for off-street parking shall be the sum of the requirements of the several uses computed separately.
D. Owners of two or more uses, structures or parcels of land may agree to utilize jointly the same parking and loading spaces when the hours of operation do not overlap; provided, that satisfactory legal evidence is presented to the planning commission in the form of deeds, leases, or contracts to establish the joint use.
E. Off-street parking spaces for dwellings shall be located on the same lot with the dwelling. Other required parking spaces shall be located not farther than 500 feet from the building or use they are required to serve, measured in a straight line from the buildings.
F. Required parking spaces shall be available for the parking of operable passenger automobiles of residents, customers, patrons and employees only, and shall not be used for storage of vehicles or materials or for the parking of trucks used in conducting the business or use.
G. Unless otherwise provided, required parking and loading spaces shall not be located in a required yard.
H. Design Requirements for Parking Lots.
1. Areas used for standing and maneuvering of vehicles shall have durable surfaces maintained adequately for all-weather use and proper drainage shall be provided.
2. Parking spaces along the outer boundaries of a parking lot shall be contained by a curb at least four inches high and set back a minimum of four and one-half feet from the property line or by a bumper rail.
3. Artificial lighting which may be provided shall not create or reflect substantial glare on any adjacent dwelling.
4. Access aisles shall be of sufficient width for all vehicle turning and maneuvering.
5. Groups of more than four parking spaces shall be served by a driveway so that no backing events or other maneuvering within a street other than an alley will be required.
6. Service drives to off-street parking areas shall be designed and constructed to facilitate the flow of traffic, provide maximum safety of traffic access and egress and maximum safety of pedestrians and vehicular traffic on the site. The number of service drives shall be limited to the minimum that will allow the property to accommodate and service the traffic anticipated. Service drives shall be clearly and permanently marked and defined through use of rails, fences, walls, or other barriers or markers on frontage not occupied by service drives.
7. Service drives shall have a minimum vision clearance area which is formed by driveway centerline, the street right-of-way line, and a diagonal straight line joining said lines through points 20 feet from their intersection. See example below:
