Stormwater Management

The New Hampshire Department of Environmental Services has released a new document to assist shorefront landowners entitled A Shoreland Homeowner’s Guide to Stormwater Management.  If you might be producing runoff directly into the lake during periods of high rains you should know that it adversely impacts the quality of our pond water and in most cases can be easily corrected. The A Shoreland Homeowner’s Guide to Stormwater Management provides several simple and cost effective practices shoreland homeowners can use to reduce and prevent polluted stormwater runoff from roofs, patios, lawns and driveways. These practices can be used to meet the provisions of the Comprehensive Shoreland Protection Act (CSPA), which helps protect the state’s surface waters by placing limits on development that contribute to stormwater runoff.
The guide consists of an introductory document and nine guidance sheets for the installation of: dripline trenches, drywells, new infiltration steps, retrofit infiltration steps, infiltration trenches, paths and walkways, rain barrels, rain gardens and water bars.  A copy of the guide can be found online at
