B.To provide design standards for parking facilities and driveways that minimize harm to motorists and private property, provide adequate emergency vehicle access, and to protect the safety and capacity of public streets.
C.To ensure that the number of off-street parking spaces does not impact adjacent residential areas from encroachment of commercial parking into neighborhood streets.
D.To minimize the impacts of stormwater runoff from off-street parking facilities due to erosion and pollution of water bodies.
240-10.2 Applicability.

Vehicle and bicycle parking shall be in accordance with this Chapter of the UDO.

240-10.3 Parking surfaces.
A.In any non-residential district, the parking of any vehicle on other than a paved surface, or other system approved by the Director, is prohibited.

Any recreational vehicle or non-motor vehicle shall only be parked in in the side or rear yard on a paved surface or approved porous or grassed paving system. Any recreational vehicle or non-motor vehicle may be parked in the front yard for loading and unloading purposes for no more than 48 hours. Any vehicles parked in the side or rear yard not in a carport or an enclosed structure must be parked at least 10 feet from the property line. Vehicles or equipment used for agricultural purposes with three or more acres are exempt from hard surface requirements if parked outside of the required front setback.
C.Maximum allowable paved parking or hard surface area in the front yard of single-family residential development, excluding walkways and required sidewalks:

§ 240-20

Parking Space Requirements

240-20.1 Minimum Parking Space Requirements.

The minimum number of parking spaces shall be determined based on the spaces required for principal uses from the Table of Minimum Parking Requirements, unless the development qualifies for a reduction in minimum parking requirements as provided in Section 240-30 or is located within a zoning district that does not require minimum parking. There shall be no minimum required parking within mixed-use developments. Where parking requirements for any use are not specifically defined in the Table of Minimum Parking Requirements, such requirements shall be determined by the Director based upon the most comparable use specified herein, and other available data.

240-20.2 Maximum Parking Requirements.

Maximum parking requirements are established in order to promote efficient use of land, enhance urban form, encourage alternate modes of transportation, provide for better pedestrian movement, reduce the amount of impervious surface and protect air and water quality.

A.Each automobile space shall be a minimum of 9 feet wide and 18 feet deep for perpendicular spaces.

Angled parking spaces shall be a minimum of 9 feet wide and 20 feet deep. Parallel parking spaces shall be a minimum of 9 feet wide and 22 feet deep. All spaces are measured from face-of-curb.

If off-street parking is provided wholly within a parking structure, there shall be no maximum parking requirement.

240-30.4 Pervious Parking Surface.
