18.54.090 Development and Maintenance:
A. Every parcel of land hereafter used for parking purposes shall be developed and permanently maintained in accordance with the following requirements:
1. Surfacing.
a. Parking areas shall be surfaced with an asphaltic or cement binder pavement or other approved material. Parking areas shall be built on a suitable base so as to provide a durable and dustless surface and shall be so graded and drained as to properly dispose of all surface water on site.
b. Asphalt, brick, concrete paving, and interlocking paving blocks, including semi-pervious systems that retain space for vegetation, are acceptable paving materials.
c. All parking surfaces shall be maintained in sound condition free of weeds, dust, trash, and debris, potholes and other hazards.
d. Any parking lot adjacent to an existing paved street shall be maintained in hard surface paving, including parking spaces, access aisles, and all areas to be driven on by vehicles.
2. Striping.
a. All required stalls, aisles, loading zones, fire lanes, and no parking areas shall be striped or otherwise designated to provide for the safe loading, unloading, parking and storage of vehicles.
b. Single-family residential and two (2) family residential are exempt from striping requirement.
3. Parking Lot Lighting. Any lighting used to illuminate a parking lot shall be directed and shielded as to not illuminate surrounding properties. Light standards shall not exceed eighteen feet (18') in height measured from grade to the highest point of the equipment. In instances where it can be established that additional height is required for health and safety reasons, an additional five feet (5') in height is allowed subject to review and approval by the Building Official.
B. Low impact development (LID) is encouraged for all parking areas. In parking lot design, this can be achieved with the use of the following design features:
1. Pervious paving material.
2. Flat curbing to encourage stormwater flows to drainage facilities.
3. Vegetative islands and perimeter buffers, planted with native plant species tolerant of and adapted to the amount of moisture anticipated in the island or buffer.
4. Vegetated islands and medians located below grade so water will flow to them.
5. Vegetated, natural drainage swales.
6. Creation of wetland cells planted with appropriate plant species and strategically located to capture runoff.
7. Grading across the lot to encourage runoff flows to drainage areas. (Ord. 2929, 8/13/19)
