Effective Impervious Cover Tool

 

Effective Impervious Cover Tool   
DNR Rule 391-2-3-.02 (4) Marshlands Buffers
for Upland Component of the Project

 
On February 28, 2007, the Department of Natural Resources Board adopted rules that established regulations that apply to the upland component of a project requiring a Coastal Marshlands Protection Act permit.  The new regulations establish marshlands buffer, stormwater management, and impervious cover standards to protect coastal marshlands of the State. 
 
 The new rules apply primarily to commercial, community and public projects such as marinas, community docks, fishing piers, boat ramps, and bridges which require Coastal Marshlands Protection Act permits. The rules do not apply to private residential docks or marshfront property that does not have a project requiring a Coastal Marshlands Protection Act permit.  
 
The regulations require that pervious surfaces must be maximized and total impervious area minimized in the project area when practicable, with a goal of no more than 15% effective impervious cover, taking into consideration existing structures and available land within the upland component of the project area.
