§ 6-146. Minimum construction standards for off-street parking areas.

(a)

The builder shall submit to the building official a geometric design in the form of a scaled drawing for any proposed off-street parking area, along with a survey plat showing the location and the size of the area for the proposed parking site and topography showing the drainage plan. The building official shall approve the geometric drawing before a permit shall be issued under this article for either permanent or temporary placement.

(b)

All off-street parking areas shall be constructed by one of the following minimum standards:

(1)

Commercial ordinary passenger-car areas: Five and one-half (5½) inches of 2500 PSI concrete reinforced with No. 6 wire mesh poured on a sub-base compacted to ninety-five (95) percent density; or

One and one-half (1½) inches of hot-mix asphalt laid on a six-inch compacted limestone or crushed concrete base on a sub-base compacted to ninety-five (95) percent density; or

Six (6) inches of crushed concrete of a one-half-inch minimum aggregate size laid on a sub-base compacted to ninety-five (95) percent density when used in conjunction with the operation of boat stalls.

(2)

Commercial heavy truck lanes: Each commercial business which provides a separate loading/docking area shall designate all delivery routes designed to facilitate delivery and/or transportation of products and such areas shall be clearly defined on the parking lot drawings. Five and one-half (5½) inches of 3000 PSI concrete, reinforced with #4 rebar at twenty-four (24) inches O.C.E.W., or three (3) inches of hot-mix asphalt laid on an eight-inch compacted limestone or crushed concrete base on a sub-base compacted to ninety-five (95) percent density shall be required in these locations.

(3)

Equipment and storage yards: All areas that are required to comply with parking requirements shall be constructed from concrete or asphalt with a compacted base and/or sub-base as described above. The balance may be constructed of six (6) inches of crushed concrete or crushed limestone with a one-inch minimum aggregate size.

(4)

Multi-family residential: Five and one-half (5½) inches of 2500 PSI concrete reinforced with No. 6 wire mesh poured on a sub-base compacted to ninety five (95) percent density. All pad sites constructed for commercial solid waste receptacles and solid waste truck-loading operations shall be five and one-half (5½) inches of 3000 PSI concrete reinforced with #4 rebar at twenty-four (24) inches O.C.E.W. poured on a sub-base.

(5)

One- and two-family residential: Three and one-half (3½) inches of 2500 PSI concrete reinforced with No. 6 wire mesh poured on a sub-base compacted to ninety-five (95) percent density and with one-inch × four-inch redwood or treated pine expansion joints installed, not to exceed twelve and one-half (12½) feet in any direction; or

One and one-half (1½) inches of hot-mix asphalt laid on a six-inch compacted limestone or crushed concrete base on a sub-base compacted to ninety-five (95) percent density.

(c)

In commercial and residential off-street parking areas, fiber-mesh concrete may be used to reduce the required reinforcement in paving; providing an engineer certifies on the drawings that the strength of the concrete is not reduced. However, fiber-mesh shall not be used to substitute reinforcing in sidewalks or driveway approaches within the public right-of-way.

(d)

All commercial off-street parking areas and equipment/storage yards not constructed of poured concrete shall be permanently held true to square by a two-inch × eight-inch treated wood form with treated stakes or by a concrete curb six (6) inches in width and having a depth that extends to the bottom of the base material. Such concrete form shall have one (1) #3 rebar placed at mid-depth.

(e)

A six-inch curb or wheel stop (pin or epoxy to pavement) shall be required at all parking spaces that abut a public right-of-way, property line, or building in accordance with section 6-148. A wheel stop may serve two (2) parking spaces.

(f)

All parking spaces shall be striped using four-inch wide painted lines and all handicapped markings shall comply with American Disabilities Act requirements.

(g)

Construction of an off-street parking area on a public utility easement shall be allowed. Off-street parking constructed on a public utility easement shall provide an expansion joint placed along the easement line and such parking area shall be constructed with a compacted flexible base with appropriate asphalt, complying with minimum paving standards. Should any utility work become necessary within the easement, the owner of such property shall repair all damages, and all costs associated with such repairs shall be totally borne by the owner.
