Stormwater/Infiltration Designs

In addition to any local requirements, RCCD utilizes the NH Alteration of Terrain Rules and NH Stormwater Manual as the basis for evaluating minimum soil and design criteria for projects even if they do not require Alteration of Terrain permits.  This includes Site Specific Soil Mapping and test pit requirements for the design of infiltration basins.  For more information see:  http://des.nh.gov/organization/divisions/water/aot/index.htm
