Promoting Wise Management of Natural Resources in Greene County, New York Since 1961

mtl-constructionThe Greene County Soil & Water Conservation District recently completed construction on a stormwater retrofit project in the Village of Tannersville. The project site is the long-vacant Marian Center Building which will soon become the home of the Mountain Top Library and Learning Center. The District’s retrofit project will protect water quality from the negative impacts of stormwater runoff from the site by utilizing low impact development and better site design practices.

These practices will help protect water quality and ecosystems from the negative impacts of stormwater.

The District is very happy to be involved in implementing this project in partnership with the Mountain Top Library.  Once completed, the new Mountain Top Library and Learning Center will be a state-of-the-art facility with expanded library catalogue, programming, and services.  In addition to protecting water quality, the Mountain Top Library Stormwater Retrofit Project will educate the public on stormwater and the various techniques available to mitigate existing and future stormwater impacts.

The District was able to secure funding for the Mountain Top Library stormwater retrofit project through the Stream Management Implementation Program (SMIP, a grant program administered by the District and NYC DEP), the Catskill Watershed Corporation, and the ACOE Water Resources Development Act (WRDA) administered by NYSDEC.
