    Angle of Parking Space
    (Degrees)     		Aisle Width

    (Feet)     		Total Width of Two Tiers

    2.

    Angled parking with one-way aisles shall be utilized where possible to reduce the total impervious area.

    3.

    Surfacing.

    a.

    Within the Grand Mound, Tenino, Rainier, and Yelm unincorporated urban growth areas parking spaces shall be surfaced with asphalt, concrete, or other approved dust-free hard surface.

    b.

    Outside urban growth areas, parking areas shall be surfaced with asphalt, concrete, compacted gravel or other approved hard surface.

    c.

    Parking spaces included in the site plan which are above the maximum number of spaces required in this Section or that are used infrequently (less than thirty days per year) shall be constructed of an alternative paving surface unless site and soil conditions make pervious surfacing infeasible, as determined by the approval authority. The alternative paving surface shall be designed and constructed to not track material into the public right-of-way and in accordance with the Drainage Design and Erosion Control Manual (current edition) and the manufacturer's recommendations. A maintenance agreement may be required to ensure such surface is properly maintained.

    4.

    Hard surface parking areas shall use paint, paving bricks, or similar devices to delineate parking spaces. Areas paved with lattice block pavement, gravel, or grass parking areas shall use wood or concrete wheel guards or wheel stops at the end of parking spaces or paving bricks, concrete strips or similar devices on the sides of spaces to delineate parking spaces.

    5.

    All parking spaces shall be designed to prevent egress by backing out onto any state highway, collector or arterial street.

    6.

    Bumper stops, curbing or wheel chocks shall be provided to prevent any vehicle from damaging or encroaching upon any sidewalk or upon any building adjacent to the parking area. Curbing shall be designed to allow drainage into landscaped areas and stormwater facilities.

    7.

    All parking spaces shall be nine feet in width and eighteen feet in length. At the developer's option, a maximum thirty-five percent may be marked "compact only" with a dimension of seven and one-half feet by fifteen feet. At the developer's option, ten percent may be marked "oversize" with a dimension of nine feet in width by twenty feet in length.

    8.

    Parallel parking spaces shall be twenty feet in length and eight feet in width, with maneuvering space of three feet for every two vehicles. Driveways and other spaces not occupied by parking may be used to obtain the required maneuvering space.
