Stormwater Projects

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 scheduled public meetings in 2016 to review potential project ideas with area residents and received funds in 2017 to implement projects.  Project implementation may begin in 2018.  Please contact us if you are interested in more information.

Castleton Watershed 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 continued through December, 2016.

During 2017, the District, with assistance from Fitzgerald Environmental Associates, identified 74 projects through the Castleton Headwaters Stormwater Assessment.  Project partners hope that 2018 will bring the implementation of several of these projects.  Please contact the District for more information about potential projects in your area.

Lake St Catherine Stormwater Planning

The District recently received a grant to both identify stormwater projects around the lake and to work with homeowners on Lake Wise certification.  The stormwater study area includes the entire Lake St Catherine and Wells Brook watershed area.  The area for the Lake Wise assessment and certification program includes shoreline properties along all areas of the lake.  Please contact us if you would like a Lake Wise consultation.  Consultations will be available beginning in June 2018 and ongoing for about a year, depending on funding and interest level of the residents.
