All vehicular driveways, parking spaces, and areas utilized for the maneuvering of vehicles must be surfaced in accordance with this Chapter.

1. Surfaced areas must be constructed on properly drained, well-compacted subgrade, that is free of organic materials. Minimum pavement structure must be:
2. A. Three and one-quarter inches Portland cement concrete having a compressive strength of 2,000 psi after 28 days, or
3. B. One and one-half inches of asphalt concrete placed over a base of 4 inches of crushed stone or gravel, or
4. C. Grid paving blocks, paving stones or materials with adequate spacing for drainage infiltration, or other stormwater management control surfaces. Where such surfaces are provided in accessible parking and as part of an accessible pedestrian path, the surfaces must meet accessibility standards of the Building Code.

1. Surfaced areas must be constructed on properly drained, well-compacted subgrade, that is free of organic materials. Minimum pavement structure must be:
2. A. Two inches of asphalt concrete on 4 inches of 1-inch minus, compacted crushed rock; or
3. B. Five inches of Portland cement concrete having a compressive strength of 3,000 psi after 28 days, or
4. C. A driveway surfaced as per Section 24.45.020 for the first 40 feet contiguous with the right-of-way paving and the remaining portion of 8 inches of 1-inch minus, compacted crushed gravel over filter fabric, or
5. D. Grid paving blocks, paving stones or materials with adequate spacing for drainage infiltration, or other stormwater management control surfaces. Where such surfaces are provided in accessible parking and as part of an accessible pedestrian path, the surfaces must meet accessibility standards of the Building Code.

Surface of parking, storing, and maneuvering areas for vehicles and motorized equipment not regulated elsewhere in this Chapter must be by a method approved by the City Administrator that will effectively eliminate dust, mud, or other contaminating elements on surrounding street areas and/or abutting property and be constructed of materials capable of supporting the maximum axle weight of the largest piece of equipment. At each street entrance, a concrete or asphalt driving apron must extend from the right-of-way paving at least 40 feet into the surface area.

Private street improvements must consist of 1-1/2 inches of Class "C" asphalt concrete on 1-1/2 inches of Class "B" asphalt concrete on 6 inches of 1-1/2 inch minus compacted crushed gravel upon a compacted subgrade that has achieved 95 percent compaction.

No gates or other barriers that would restrict vehicles or pedestrians from using the private street may be located on a private street approved under this Section.
