(A) Pursuant to state law, an adequate storm and surface water drainage system shall be installed. The plans for such a system shall be prepared by a registered professional civil engineer. In approving such a plan, the Plan Commission may require off-site improvement of drainage outlets to adequately handle the drainage from the subdivision. In such a case, a statement of review from the U.S. Soil and Water Conservation District shall be presented to the Plan Commission with the final plat.
(B) If, in the opinion of the Plan Commission, the natural surface drainage is adequate, easements for the natural surface drainage shall be provided.
(C) All areas designated by the State Department of Natural Resources as a part of the 100-year flood plan shall have all required permits from the Department of Natural Resources prior to approval of the final plat by the Board of Commissioners.
(D) Retention basin construction may be required prior to any construction in a subdivision at an appropriate location to collect any sedimentation or erosion that would be caused by building of roads or construction of buildings. The retention basin design shall be shown on the site plan and approved by the Plan Commission prior to construction. The basin shall be removed only after approval of the Planning Department.
(E) Permanent basin construction may also be required to meet state law.
