The Town of Swanzey sought to revitalize a river access park in a neighborhood. D&K provided design and permitting assistance for improvements to the park, including new landscaping, stormwater drainage improvements, a new shelter, a rooftop boat launch, and other new site elements. Our project team engaged with the Ashuelot River Local Advisory Committee, Town…
The Gray Farm needed a new waste storage facility and leachate collection system. D&K visited the site and conducted field survey and mapping, soil investigations, preliminary engineering, final design, and construction phase services while following the requirements of the NRCS EQIP program.
The North Attleboro National Fish Hatchery is a pond complex consisting of large rearing ponds supplied and drained by a network of water pipes and valves, which are equipped with concrete water control structures (called kettles) that control the pond water levels, manage the water between ponds, and drain the ponds. The USFWS required selective…
Located along the Konkapot River, the Berkshire National Fish Hatchery maintains lake trout brood stocks for restoration efforts in the Lower Great Lakes and raises brook trout for local recreation and educational programs throughout Berkshire County. The existing water supply system consisted of three shallow gravel wells and two springs that are connected, piped, and…
Sucker Brook was a deeply incised stream channel that threatened nearby infrastructure and sent an estimated one ton of phosphorus per year downstream toward Lake Champlain. The project goals included a reduction of sediment loading and erosion and the restoration of aquatic and riparian habitat while minimizing construction and maintenance costs. D&K prepared conceptual and…
The Chittenden County Regional Planning Commission and the City of South Burlington were interested in understanding how to improve pedestrian, cyclist, and vehicular safety and mobility at the Spear Street and Swift Street intersection. D&K provided analysis of the existing conditions, alternatives analysis, traffic modeling, intersection layouts in CAD, public engagement using an ArcGIS StoryMap…
The New Hampshire Department of Environmental Services identified the 1861 concrete and masonry Union Village Dam as high-hazard and deficient in a number of areas. The owners’ preferred option was to remove the dam to reduce potential hazards and remove a hydraulic and aquatic organism passage barrier from the river, restoring the river to a…
The goal of this project was the removal of Stone Pond Dam and associated structures, the restoration of Scott Brook to a free-flowing condition, and the removal of an unnatural barrier to aquatic organism passage (AOP). D&K developed a study and provided a removal design that considered H&H, sediment transfer, and soils and identified alternatives…
The Cross Brothers Dam was no longer used for a long-defunct mill, and the impoundment had silted into the dam’s crest. The dam, built in 1924 and classified as a Low-Hazard dam by the State of Vermont, was a complete obstruction to aquatic organism passage with the potential to further damage water quality. D&K provided…
