Green Infrastructure for Stormwater Management in NH Coastal Communities
The Green Infrastructure Project provides resources and support for communities to improve stormwater management. We are supporting pilot projects in six towns, and are developing workshops, fact sheets and other resources to help communities develop better regulations, train staff and build stormwater treatment systems.
What is Green Infrastructure?
Green infrastructure uses natural ‘green’ process such as plants to help control rain runoff from surfaces. This can include buffers along streams, constructed systems that treat runoff by infiltrating or filtering the water, or non-structural strategies such as incentives or education to encourage homeowners to protect water quality, or regulations that require better stormwater control for new construction. For a list of strategies available through this project click here. A Complete Community Approach uses green infrastructure throughout all aspects of community planning.
Why do we care about stormwater and how does Green Infrastructure help?
Stormwater is rain runoff that flows across parking lots, roads or other hard surfaces. The runoff contributes to flooding and can carry pollutants including road salt and nitrogen into our rivers, lakes and the Great Bay. Existing stormwater management systems designed to control runoff and protect life and property are not always able to handle the large storm events that New Hampshire has experienced over the last several years. Better water resource management will reduce infrastructure costs and help to alleviate flooding.
Congratulations to our Implementation Communities!
The project team selected six proposals for funding. The communities of Exeter, Stratham, Portsmouth, Rochester, Durham and Brentwood will work with us on projects to improve stormwater management. See below for descriptions.
