CONCORD, Mass. – The town of Glastonbury is seeking a permit from the U.S. Army Corps of Engineers, New England District to conduct work in waters of the United States in conjunction with stormwater drainage construction in Glastonbury, Conn.
The town of Glastonbury is proposing the discharge of dredged or fill material and associated excavation for the construction of a stormwater drainage system in order to alleviate severe flooding at the intersection of Dug Road and Tryon Street in Glastonbury. As a result of the project, the existing drainage area will increase from 101 acres to 152 acres, resulting in more frequent flooding of the wetlands adjacent to the Connecticut River. A 1,650-foot-long, 48-inch diameter pipe will be installed to the north of 302 and 306 Tryon Street and will discharge into a rip rap scour hole in a low-lying wetland area to the west.
A weir structure set at elevation 7.5 will be installed at the western end of the wetland in order to relieve flooding in the agricultural fields to the south as a result of increased stormwater flows into the wetland. As a result of the weir, the maximum water surface elevation within the wetland will be at or below pre-development conditions. A permanent pool of water will remain in the wetland between elevations 5.0 and 7.5. A second, 550-foot-long, 36-inch diameter pipe will be installed to the west of the weir, to the north of an existing drainage swale that will discharge into a rip rap apron and then directly to the Connecticut River.
Direct and permanent impacts to inland wetlands are 5,700 square feet (0.13 acre). Direct and permanent impacts to tidal wetlands are 900 square feet (0.02 acre).
The application for the federal permit was filed with the Corps in compliance with Section 10 of the Rivers and Harbors Act, which provides for federal regulation of any work in, or affecting navigable waters of the United States; and with Section 404 of the Clean Water Act, which regulates the discharge or fill of material in U.S. waters, including wetlands. The Corps public notice, with more detailed information, can be viewed at http://www.nae.usace.army.mil/Regulatory/Public%20Notices/.
