Any person desiring a grading permit shall submit a storm water management plan with the following information for the entire site upon which any grading, stripping or cutting is to be done:
(a) Name, address and contact information of owner or developer, and contact information for consulting firm, if applicable.
(b) Filing fee for plan review.
(c) A plat or boundary line survey of the entire site on which the grading, stripping or cutting is to be done showing existing topography, structures, wetlands, streams, and steep slopes or sensitive areas.
(d) Project description of proposed features on and surrounding the proposed development including topography, buildings, and other structures, immediate receiving steams, drainage patterns, limits of clearing and soil disturbing activities, and structural Best Management Practices and other storm water management practices.
(e) Description of types and locations of soil conditions on the site. Information as to soil conditions is available from Little Kanawha Soil Conservation District’s Erosion and Sediment Control Handbook for Urban Areas, 1972.
(f) The plans and specifications, submitted as part of the storm water management plan shall contain all temporary and permanent soil erosion and sedimentation control Best Management Practices necessary at the site using appropriate soil erosion control measures in accordance with the standards and specifications of the Little Kanawha Soil Conservation District’s Erosion and Sediment Control Handbook for Urban Areas, 1972, and the West Virginia Erosion and Sediment Control Handbook. The plans and specifications shall include the location and size of the Best Management Practices and their maintenance requirement during and after construction.
(g) A calculation of the percent imperviousness cover for both the pre-development and post-development site conditions.
(h) Design calculations for all storm water management practices shall demonstrate that the peak rate of runoff occurring on the development drainage area from a one-year frequency, twenty-four hour storm, shall not exceed the peak rate of runoff from the same storm event under pre-development conditions.
(i) All storm water management practices shall have easements sufficient to provide access to the City for inspections and maintenance. Easements and covenants shall be approved by the City prior to approval of a final plat and shall be recorded with the County Clerk and on all property deeds. Unless otherwise required by the City Engineering Division, storm water management practices in subdivisions, including basins, ponds and wetlands, shall be on separate lots held and maintained by an entity of common ownership.
(j) For all redevelopment projects, design shall include nonstructural and structural Best Management Practices that are designed to result in net equivalent reduction in impervious cover of at least twenty percent (20%) at the site. Where the City Engineering Division determines that site constraints prevent a reduction in impervious cover, the following practical alternatives may be used: fees paid in an amount specified by the City Engineering Division and approved by City Council; implementation of off-site storm water management practices, watershed or stream restoration, retrofitting of existing storm water management practices or other practices approved by the City Engineering Division.
(k) A sequence of construction schedule indicating the anticipated starting and completion dates of the development sequence and the time of exposure of each area prior to completion of effective erosion and sediment control measures.
(l) All applications for grading permits shall be made in writing upon a form provided by the City Engineering Division and shall be made under oath and signed by the owner of the site, or for the owner by the contractor proposing to do the work, or another authorized person.
