Findings: Stormwater Management

This report card is calculated based on the responses to eight questions regarding Stormwater Management and what percentage of those responses attains the minimum protective standards suggested by NHDES or PREP.

Click on question to view results:

1. Does the municipality have stormwater management regulations?

Check out the Southeast Watershed Alliance Model Stormwater Standards for Coastal Watershed Communities for specific examples of model stormwater regulations that can be adopted in your community.

2. Does the municipality have less than or equal to 9% Impervious Cover?

3. Is the minimum area of soil disturbance that “triggers” application of the municipality’s stormwater management regulations less than or equal to 20,000 sqft?

4. Does the municipality have a cap of 10% effective impervious cover (EIC) for new development in residentially zoned lots of 1 acre or more?

5. Do the municipality’s existing regulations require the use of Low Impact Development (LID) techniques to the maximum extent practicable for new development and re-development?

6. Do the municipality’s stormwater management regulations reflect the minimum design criteria for water quality volume/flow (WQV/WQF), groundwater recharge volume (GRV), and peak flow control defined in the NH Stormwater Management Volume 2?

 

PREP is part of the U.S. Environmental Protection Agency’s National Estuary Program, a joint program between local, state and federal agencies established under the Clean Water Act with the goal of protecting and enhancing nationally significant estuarine resources. PREP is supported in part by an EPA matching grant and is housed within the School of Marine Science and Ocean Engineering at the University of New Hampshire.
