Whenever an off street parking lot is a requirement, such lot shall be laid out, constructed and maintained in accordance with the following regulations:
(A) Adequate ingress and egress to the parking lot by means of clearly limited and defined drive shall be provided for vehicles. All drives and aisles shall be surfaced in a manner equivalent to that which is hereinafter provided for parking areas.
(B) All spaces shall be laid out in the dimensions of ten feet by twenty feet (10' x 20') or two hundred (200) square feet of space, exclusive of area required in subsection (C) of this section.
(C) All space shall be provided adequate access by means of maneuvering lanes.
(D) Where the parking lot is contiguous with a residentially zoned district which has common frontage in the same block with the parking lot, there shall be established a setback equal to that required for buildings in the applicable residential zone buffered in accord with chapter 15 of this title.
(E) Where a parking lot lies across the street and opposite a residentially zoned district wherein the lots front on such street, there shall be established a setback line ten feet (10') from the front lot line. In lieu of this setback a buffer strip may be provided (see chapter 15 of this title).
(F) Where the parking lot lies across the street and opposite or contiguous to and in the same block with residentially zoned property which has only side lot lines on the street, there shall be established a setback line ten feet (10') from the lot line. In lieu of this setback a buffer may be provided.
(G) Where the parking lot abuts rear property lines of a residentially zoned district, there shall be established a setback line of ten feet (10') from the rear property line. In lieu of this setback a buffer may be provided.
(H) The land between the setback line and the lot line in a parking lot is for the purpose of this chapter called a buffer strip.
(I) There shall be bumper stops or wheel chocks of concrete or similar permanent material, provided so as to prevent any vehicle from projecting over the buffer strip. (Ord. 567, 11-1976)
(J) Wherever a buffer strip is not practical or reasonable, a continuous unpierced masonry wall of specified height and materials may be substituted if approved by the city council after hearing and recommendation by the joint planning and zoning commission. (Ord. 567, 11-1976; amd. Ord. 3041, 12-3-2013)
(K) Where buffer strips are not required, bumper stops or wheel chocks will be provided, so located as to prevent any vehicle from projecting over the lot line.
(L) The parking lot shall be drained to eliminate any standing surface water.
(M) The surface of the parking lot excepting the buffer strips shall have dust free concrete or asphaltic surfacing.
(N) Plans for the layout of the parking lot must be approved by the zoning administrator. Plans for the layout of the parking lot shall show a total dimension across two (2) tiers of spaces and one aisle (maneuvering lane) of at least the following for the various patterns:
1. Ninety degree (90°) pattern: Sixty feet (60') for two (2) tiers of space, including one aisle (maneuvering lane), with the minimum aisle being twenty feet (20') in width.
2. Sixty degree (60°) pattern: Fifty five feet (55') for two (2) tiers of spaces including one aisle (maneuvering lane), with the minimum aisle being fifteen feet (15') in width.
