The Hooksett Hydroelectric Project includes a 1.6 MW run-of-the-river hydroelectric power generation dam that is a barrier to aquatic organism passage (AOP), including Blueback Herring, American Eel, and American Shad. D&K worked closely with officials from the U.S. Fish and Wildlife Service and the National Oceanic and Atmospheric Administration regarding the details of the design,…
To support continued and upgraded use of its site for light industrial purposes, Chroma Tech needed to stabilize an adjacent slope. The aim of the project was to improve site stability and minimize erosion and stormwater pollution directly behind the facility. D&K evaluated the site and worked with regulators, the client, and a grant funding…
The US Forest Service sought to expand their supervisor’s office and relocate from downtown Rutland to be closer to forest resources in the Green Mountain National Forest. Under successive contracts, D&K worked with the Forest Service, regulators, and other stakeholders to develop site design concepts, survey the area, identify natural resources, secure permitting, and provide…
The City of Essex Junction needed to meet the town’s phosphorous TMDL requirements by designing a subsurface gravel wetland, as proposed by the Indian Brook Flow Restoration Plan. D&K designed a gravel wetland to treat the stormwater discharge from a watershed associated with three homeowners’ associations (HOAs), roadways, and sidewalks. Our project team coordinated with…
D&K provided mechanical, electrical, structural, landscape architecture, and civil design and retro-commissioning services for modifications of nine state facilities, converting from district steam to various types of local heating systems. D&K designed a new steam boiler plant—located remotely from the buildings it served—for the New Hampshire State House and two other State buildings. The project…
As part of the Great Streets BTV project, D&K assisted with the redesign of City Hall Park. The overall goal of the project was to make Burlington’s downtown core more appealing to users of all modes of transportation and enhance the area’s natural and cultural assets. D&K developed designs for civil, stormwater, and utilities to…
Following the inception of Vermont’s Three-Acre Stormwater Rule, schools throughout Vermont needed to adapt their campuses to manage stormwater in accordance with Vermont Stormwater General Permit 3-9050. To help schools successfully manage these challenges, D&K has provided engineering and environmental services for feasibility studies and the design of stormwater improvements for five schools. The projects…
Located on the Otter Creek, the Huntington Falls Hydroelectric Project is a historic facility that required redevelopment. The D&K team assessed the two non-operational turbines and related appurtenances, the trash rack, and raker upgrades to the Unit 3 turbine following FERC relicensing. Additional D&K services included design and coordination to upgrade all three turbines, resulting…
D&K provided design-build renovations on this 9,000-SF fire station. Upgrades included administrative offices, a training room, and a high-bay apparatus area for eight emergency vehicles. Our civil/site team provided permit work and applications, building surveys, grade development, stormwater management, driveway and parking areas, ADA-accessible walkways, and three 14,000-gallon buried water storage tanks for emergency vehicle…
