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 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” methods to help reduce problems associated with rain runoff from surfaces that have been altered by people. Examples include shrub and tree buffers along streams, engineered systems that treat runoff by infiltrating or filtering the water on site, incentives or education to encourage homeowners to protect soil and water, 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. Instead of soaking into soil on site, the runoff tends to be sent elsewhere in large volumes. This contributes to flooding and the untreated water can carry pollutants including nitrogen and toxic automobile lubricants into our rivers, lakes, and Great Bay. Many stormwater management systems designed to control some runoff are not always able to handle the large storm events that New Hampshire has experienced over the last several years. Green Infrastructure is a cost-effective way to keep more water on site, remove pollutants, and help to alleviate flooding. Find out more below:
Congratulations to our Implementation Communities!
The communities of Exeter, Stratham, Portsmouth, Rochester, Durham and Brentwood were selected to work with us on projects to improve stormwater management. See below for descriptions.
