The Planning Commission or Planning Officer shall not issue a Permit or Certificate of Compliance for an Adults Only establishment that fails to make adequate provisions for storm or flood water runoff by use of channels or basins. An Adults Only Establishment shall comply at all times with the following provisions:
(a) Adequate provisions shall be made for storm or flood water runoff by use of channels or basins based on a twenty-five (25) year frequency for storm drains with an overflow designed at a fifty (50) year frequency;
(b) In areas that are experiencing stormwater problems, a stormwater management facility shall be provided to accommodate a post-development storm with a ten (10) year, twenty-four (24) hour frequency, to be released at a rate not to exceed the predevelopment discharge for storm with a two (2) year, twenty-four (24) hour frequency;
(c) A stormwater management facility with a maximum of a ten (10) foot total water depth shall have the as-built facility certified by a registered professional engineer as to design, specifications and construction to meet the requirements of this Article and the design standards of the United States Natural Resources Conservation Service as found in the "Natural Resources Conservation Technical Guide, Standards and Specifications for Ponds," January 1988;
(d) A stormwater management facility that exceeds a ten (10) foot total water depth shall have the as-built facility certified by a licensed geotechnical engineer as to design, specifications and construction to meet the requirements of this Article and the design standards of the United States Natural Resources Conservation Service as found in the "Natural Resources Conservation Technical Guide, Standards and Specifications for Ponds," January 1988;
(e) A stormwater management facility shall be constructed on a common area on the Premises and shall be maintained by the Adults Only Establishment;
(f) The stormwater drainage system shall be separate and independent of any sanitary sewer system. Storm sewers, where required, shall be designed by a West Virginia registered professional engineer by the method approved by the Planning Commission or Planning Officer, and a copy of the design computations shall be submitted along with plans; and
(g) Inlets shall be provided so that surface water is not carried across or around any intersection, nor for a distance of more than six hundred (600) feet in the gutter. When calculations indicate that curb capacities are exceeded at a point, no further allowance shall be made for flow beyond that point and basins shall be used to intercept flow at that point. Surface water drainage patterns shall be shown for each and every lot and block.
