The development also includes an office building and space for the addition of up to nine single-family homes. D&K provided survey and civil engineering and D&K’s electrical engineers designed the…
The Neshobe River crosses through the heart of downtown Brandon, and the historic stone masonry bridge carrying Central Street/US 7 and numerous utilities had a history of substantially inadequate hydraulic capacity. As a demonstration of this issue, the town opened the front and rear doors of the adjacent town offices during a large storm event…
Heavy rainfall and substantial snowmelt from a storm event combined with insufficient drainage systems to wash out 2,800 LF of a vital roadway crossing a mountain. The steep and winding road serves approximately 1,400 vehicles per day and connects VT 100 and VT 12. The Town of Rochester applied for and received FHWA-ER funding to…
Two dams in a park owned by a community association were damaged by storm flows. The lower dam was breached and required design alternatives for its removal; the upper dam had to be evaluated for repairs. D&K reviewed the structural elements of both dams, the retaining wall, and the stream character upstream and downstream. Our…
The 40-year-old wastewater treatment facility, originally designed for a 20-year service life, was past due for a total treatment process change and facility upgrade. The project objectives included: utilize a state-of-the-art treatment process, design capacity for nitrogen removal, consider operational efficiencies and long-term operating costs, address issues with the location in a floodplain, and develop…
To efficiently manage the design of highway surfacing and appurtenant systems, the Vermont Agency of Transportation (VTrans) engages consultants to supplement in-house engineering, environmental, and surveying services. Since 1998, D&K has provided design for state and US highways, including interstates, urban Class 1 sections of US or state highways, major and minor arterials, and rural…
To develop a safer and dedicated cyclist and pedestrian-focused path from downtown to Gallison Hill Road, the City of Montpelier chose to develop a paved, largely off-street pathway, which shared a substantial portion of its alignment with a local railroad. Weaving through a largely urban area, the project creates an active transportation and recreation right…
Framed by a public park and a residential area and carrying a city street, Robin Hood Dam was reclassified by the State of New Hampshire as a high-hazard dam, and its spillway did not have the capacity to meet New Hampshire Dam Safety requirements. The City of Keene engaged D&K to evaluate the dam, develop…
The Upper Wilson Pond Dam is a small, high-hazard, earth embankment dam impounding a recreation pond. Recently found to be in poor condition, the dam is owned by the Town of Swanzey, and the pond is bounded by homes and properties located within the City of Keene. D&K’s project team completed a study that evaluated…
