(A) The recharge, stream channel protection and peak runoff attenuation requirements specified in the Design Manual do not apply to redevelopment projects unless specified by the Town Planning and Zoning Commission, its agent(s) or the Town Engineer.
(B) (1) All redevelopment projects shall reduce existing site impervious areas by at least 20%. Where site conditions prevent the reduction of impervious area, then stormwater management practices shall be implemented to provide qualitative control for at least 20% of the site’s impervious area. The elements and principles of stormwater qualitative control are noted in the Design Manual. When a combination of impervious area reduction and stormwater practice implementation is used, the combined area shall equal or exceed 20% of the site.
(2) Note: For redevelopment “site” in the definitions section is defined as: “... the area of new construction as shown on an approved site plan, or the original parcel.”
(3) Determination of the applicable area shall be made by Town Planning and Zoning Commission, its agent(s) or the Town Engineer.
(C) Where conditions prevent impervious area reduction or on-site stormwater management, the Town Planning and Zoning Commission, its agent(s) or the Town Engineer may consider practical alternatives including: [check legality of these alternatives]
(1) Watershed or stream restoration;
(2) Retrofitting; or
(3) Other practices approved by Town Planning and Zoning Commission, its agent(s) or the Town Engineer.
