§ 12.8. Off-street parking space layout, standards, construction, and maintenance.

Whenever the off-street parking requirements in section 12.7 above require the building of an off-street parking facility, such off-street parking lots shall be laid out, constructed and maintained in accordance with the following standards and regulations.

1.

No parking lot shall be constructed unless and until a permit therefore is issued by the building official. Applications for a permit shall be submitted to the building department in such form as may be determined by the building official and shall be accompanied with two sets of site plans for the development and construction of the parking lot showing that the provisions of this section will be fully complied with.

In all districts, the entire parking area, including parking spaces, maneuvering lanes required under this section, and driveways, shall be provided with bituminous concrete or concrete surfacing in accordance with specifications approved by the city manager. Off-street paving areas shall be drained so as to dispose of all surface water accumulated in the paving area in such a way as to preclude drainage of water onto adjacent property or toward buildings.

2.

Plans for the layout of off-street parking facilities shall be in accordance with the following minimum requirements:

OFF-STREET PARKING LAYOUT REQUIREMENTS

Parking Pattern	Maneuvering Lane Width		Parking Stall Width	Parking Stall Depth (90° Measure)	Total Depth of One Tier of Spaces Plus Maneuver- ing Lane	Total Depth of Two Tiers of Spaces Plus Maneuver- ing Lane
	(2-Way Movement)	(1-Way Movement)
0° (parallel) parking	24'	12'	8.0'	22'	20'	40'
45°	23'	12'	9.5'	13'	25'	49'
60°	24'	16'	9.5'	16'	32'	56'
90°	25'	N/A	9.5'	18'	43'	61'

 

3.

All maneuvering lane widths shall permit one-way traffic movement, except that the 90° pattern shall permit two-way movement.

4.

All spaces shall be provided adequate access by means of maneuvering lanes. Backing directly onto a street shall be prohibited.

5.

Adequate ingress and egress to the parking lot by means of clearly limited and defined drives shall be provided for all vehicles. Ingress and egress to a parking lot lying in an area zoned for other than single-family residential use shall not be across land zoned for single-family residential use.

6.

Each entrance and exit to and from any off-street parking lot located in an area zoned for other than single-family residential use shall be at least 25 feet distant from adjacent property located in any single-family residential district.

7.

A wall shall be provided on all sides of the off-street parking area abutting or adjacent to a residential district. The obscuring wall shall not be less than four feet six inches (4′6″) in height measured from the surface of the parking area.

All land between the required obscuring wall and the front property line or street right-of-way line shall be kept free from refuse and debris and shall be landscaped with deciduous shrubs, evergreen material and ornamental trees. The ground area shall be planted and kept in lawn. All such landscaping and planting shall be maintained in a healthy, growing condition, neat and orderly in appearance.

The planning commission, upon application by the property owner of the off-street parking area, may waive or modify the wall requirement by approving either an earth berm or evergreen screen in its place. The planning commission may also waive the wall requirement if in specific cases where cause can be shown that no good purpose would be served by compliance with the requirements of this section.

8.

All lighting used to illuminate any off-street parking area shall be so installed as to be confined within and directed onto the parking area only.

9.

In all cases where a wall extends to an alley which is a means of ingress and egress to an off-street parking area, it shall be permissible to end the wall not more than ten feet from such alley line in order to permit a wider means of access to the parking area.

10.

Parking aisles shall not exceed 300 feet without a break in circulation.

11.

Except for those serving single- and two-family dwellings, all parking lots shall be provided with wheel stops or bumper guards so located that no part of parked vehicles will extend beyond the property line or into required landscaped areas or pedestrianways.

12.

No parking lot shall have more than one attendant shelter building. All shelter buildings shall conform to setback requirements for structures in the district in which it is located.
