The District helps area towns, businesses and landowners understand the need for and implementation of ‘Green’ stormwater projects, or those that incorporate natural water cycle principles into urban water drainage systems. Examples of green stormwater projects include those that increase the infiltration of stormwater at the source, such as capturing water from impervious roofs or paved areas and infiltrating it into a nearby rain garden or a larger, engineered bio-infiltration area.
Increasing the infiltration of stormwater can improve the water quality in nearby streams. Unfiltered water from rain events can carry a myriad of pollutants picked up on the urban landscape and enters streams and lakes very quickly through the stormdrain system, changing the hydrology of streams and increasing erosion. Studies have shown that small increases in impervious surfaces (effects are seen around 7% impervious surface area) can drastically change the hydrology of streams and negatively impact water quality. Application of Green Stormwater Infrastructure principles can help decrease these impacts.
Pawlet Village Stormwater Planning
PMNRCD, in coordination with the Village of Pawlet, has recently identified multiple projects in the town center that may decrease the overland flow of water to Flower Brook during storm events. Stone Environmental is providing engineering expertise and is assisting the Village as they rank the identified projects for implementation. Most of the projects have received positive review from the residents and will likely be implemented. The District will schedule public meetings to review potential project ideas with area residents.

Lake Bomoseen Stormwater Planning
In August, 2015, the District signed a contract with Vermont DEC to complete stormwater planning activities in the Lake Bomoseen watershed. Residents near Crystal Beach reported large influxes of sediment at the mouth of Sucker Brook and the Lake Bomoseen Water Quality Committee was interested in identifying and mitigating the sources of sediment. This project began in the fall of 2015 and will continue through December, 2016.
Middletown Springs Stormwater Project
The Town of Middletown Springs, the Historical Society, the Volunteer Fire Department, and the Community Church applied for funds to design a green stormwater project on the town green. Runoff from each of these buildings and a town storage area causing flooding and other issues for the foundations of the historic buildings on the town green. To alleviate this issue the town would like to build an infiltration garden in the town green that will be both beautiful and functional. Initial designs were completed in early Fall 2015 and a series of public meetings are being held to help garner local support and input. Please contact us for more information.
