In response to repeated storm damage to this 1,900-ft-long, circa 1960s Army Corps granite block protection levee, the Town of Lincoln needed to repair the levee to maintain an acceptable level of service. DuBois & King evaluated the structural, hydrologic and hydraulic, civil, and structural conditions and requirements of this site along the Pemigewasset River….
Manufactured housing communities in Vermont provide practical housing solutions; however, some of these communities are disproportionately affected by environmental issues. The Vermont Department of Environmental Conservation sought consultants to provide Preliminary Engineering Reports (PERs) and design solutions that responded to the specific challenges faced by MHCs and a backlog of failing wastewater, potable water, and…
For the construction of the new US Department of Labor (DOL) New Hampshire Job Corps Center, DuBois & King’s survey crew tied into existing boundary corners and collected 1-ft contour intervals on an undeveloped 20-acre wooded parcel. Our surveyors developed the topographic survey into a 3D-model base plan to assist our design team in performing…
The City of Providence undergoes chronic and damaging flooding in the urban center. D&K is developing a Watershed Plan Environmental Assessment document to identify flood mitigation strategies along the Woonasquatucket River. The plan considers the potential impacts of alternatives on environmental and social resources. Alternatives include lowering the grade of some floodplain areas to allow…
The Addison Town Hall and Addison Community Baptist Church needed a centralized wastewater system to reestablish use of the historic Town Hall building, which sat vacant for nearly a decade. The structure required significant renovation, and its marginal (mostly clay) soils and a high water table made a conventional on-site wastewater system infeasible. At the…

The existing circa-1927 water lines were deteriorating and in need of replacement due to frequent leaks and need for emergency repairs. D&K provided design, permitting, bid, and construction phase services to replace 3,083 ft of water lines, hydrants, valves, and metering as part of a 9,110-LF distribution system. Construction of the water distribution system was…
The city completed the design of improvements to the existing wastewater pump station. Through that process, it became evident that the existing system had reached the end of its operating life, and selected components should be replaced rather than upgraded to provide increased reliability, energy efficiency, safety, and compatibility with other city pump stations. D&K…
