The purpose of the project is to protect the Delaware County Fairground and the existing main utility pole that services the Village of Walton.
The streambank was observed to be actively eroding along West Branch Delaware River and posed a significant risk to public infrastructure while also contributing a significant amount of sediment to the West Branch Delaware river. In order to maintain the safety and integrity of the utility and the public, the project consisted of removal of on-site material and placement of rock rip rap with topsoil. The rock was covered with soil to encourage vegetation growth and minimize thermal impacts to the river. Live willow stakes were planted along the embankment.
A storm event that occurred in the Town of Hamden between August 13 and August 15, 2018 resulted in streambank erosion at several locations adjacent to town-maintained roads. One of these locations, SL 4.62, is located at the Terry Clove Road, Basin Clove Road, and Coles Clove Road intersection. At the SL 4.62 site, the Basin Clove stream has eroded the road shoulder and undermined the roadway embankment. Continued lateral migration and hydraulic erosion at the toe of the roadway embankment threatens the integrity and safety of the town infrastructure. The Town of Hamden applied for grant funding through the Stream Management Program.
The project design stream length of 125 feet that included the placement of stacked and pinned rock wall along the left streambank and two (2) hardened riffles for grade control. The grade control structures would help maintain water quality by limiting any potential head-cuts from advancing upstream. This design would implement the project goals and objectives established by the Stream Management Program staff, while providing water quality benefits for the New York City Department of Environmental Protection (DEP) and communities that rely on drinking water sources from the West-of-Hudson River Watershed.
West Brook is one of the three tributaries flowing through the Village of Walton. Vertical stacked rock walls, urban development and encroachment, and a general lack of floodplain connectivity are common issues along the West Brook stream corridor through the Village. Energy dissipation is minimal and, with lateral migration inhibited, the bed of West Brook has continued to erode. At Site #8, a water main concrete encasement is exposed. Despite the adjacent floodplain enhancement project along the right bank, this crossing is at risk of being damaged or undermined during a future storm event. The Village of Walton applied for grant funding through the Stream Management Program.

The Village of Walton owns numerous underground utilities that cross three major tributaries of the West Branch Delaware River within the Village limits. At thirteen known locations, the utilities – water, sewer, or both, in close proximity – are threatened by the three tributaries’ continued streambed scour. Previous storm events, including most recently in 2006, resulted in damage to five of the thirteen crossing locations, leading to costly utility repairs, temporary lack of potable water for Village residents, and raw sewage leaks. Potential leaks could contaminate the West Branch and the Cannonsville Reservoir downstream, one of New York City’s unfiltered drinking water supply sources.
The purpose of the project is to stabilize the streambank for the property to qualify for the federal Conservation Reserve Enhancement Program (CREP) and the NYC DEP funded Catskill Stream Buffer Initiative (CSBI) on fallow agricultural riparian properties.
The CREP/CSBI pilot program was developed in 2017 by the DCSWCD, the Watershed Agricultural Council, and the NYC Dept. of Environmental Protection. The pilot program was created to merge the federal CREP and the NYC DEP funded CSBI on fallow agricultural riparian properties in Delaware County. CREP/CSBI has planted native vegetation along both the top right and top left banks of East Brook in numerous locations along the East Brook property; however, in order to complete the plantings, the streambank must be restored to a stable reach. The project included stream channel sizing, dimensioning and realignment for 740 linear feet with hardened rock toe on left and right banks near pool locations; 8 grade control structures, 1 hardened riffle, installation of sod mats and willow live stakes. Floodplain bench and multi-stage channel will provide floodplain connection while improving flood-flow and sediment conveyance.
The purpose of the project was to repair the streambank along old access road for future projects.

This project was a recommendation in the Village of Delhi Local Flood Analysis Plan. The purpose of this project was to reduce lateral stream migration of Steele Brook and the resultant sediment loading from streambank erosion within the project reach. The repair of stream channel sizing, dimensioning and realignment for 460 linear feet with stacked rock wall along the left streambank; floodplain bench; and re-vegetation of the eroding bank. Restore access route at the top of the slope; culvert replacement at two (2) stream crossings along route; and culvert replacement at three (3) drainage locations along access route. Tree removal of approximately 82 trees flagged within a 0.51 mile length of Steele Brook. These trees were identified during the 2017 Steele Brook Stream Feature Inventory as posing a significant flood threat to the Village of Delhi. Mobilization of this debris and transport downstream would lead to potential blockage of the undersized bridge within the Village.
