(A) Before a petition for primary approval is accepted, the petitioner (developer) must perform a Storm Water Mitigation Feasibility Study (Storm Water Drainage Plan), to determine if it is possible to develop the site within the standards set for storm water disposal.
(B) Provided the site is in the current or future jurisdiction of a storm water utility then the standards set by that utility shall govern. Provided however there is a conflict with other ordinances, statutes, or regulations then the most restrictive requirements shall govern.
(C) Provided there is no standard or standards for the development of a Storm Water Mitigation Feasibility Study (Storm Water Drainage Plan) then the Plan Commission may require that the general methods set forth in “A General Ordinance Establishing Storm Water Control” document number H-88-52 shall govern. The developer may petition for variance from specific elements of this standard, before the Plan Commission, giving full details of the reason for the variance.
(D) Details of the proposed compliance with storm water mitigation standards will become a major issue in the primary approval of the project.
(E) The Plan Commission shall require the certification of the storm water utility and/or the certification of a registered professional engineer before primary approval is granted.
(F) The Storm Water Mitigation Feasibility Study (Storm Water Drainage Plan) shall contain:
(1) The information required by the City Zoning Ordinance.
(2) The total rate of water delivered off site;
(3) A detailed description of the methods used for mitigation;
(4) A detailed description, including maps and drawings of the proposed infrastructure;
(5) Providing the mitigation plan requires the use of natural drainage then a detailed description of the impact of the development, on the natural drainage shall be included, including but not limited to the necessary changes in contour required.
