Otter View Park is a nature park and trail on 17-acres of Middlebury Land Trust property located along the Otter Creek, providing pedestrian access through an upland meadow, cattail marsh, wetland, and floodplain forest. Provided alternatives analysis through final design of the trail, trailhead parking, overlook viewing areas, and an 800 ft long elevated boardwalk across the wetland floodplain. Professional services included survey, civil, sanitary, structural, and hydraulic engineering; permitting; construction phase services; and engineering and permitting services for the subdivision of three residential lots associated with the property. The elevated boardwalk was designed using a helical pier foundation system enabling construction from the deck side, eliminating wetland impacts. Recycled composite fiber material was used for decking, railing surface, and bench seats.
Millstone Hill West Bike Path
D&K engineers completed the alignment analysis, developed final design, and prepared final engineering plans and contract documents for the Millstone Hill West Bike Path, a 7,100 ft-long, 10 ft-wide shared use pathway for pedestrians, bicyclists, and other non motorized users. As part of the larger Central Vermont Regional Path, the Millstone Hill West Bike Path provides connection between the Websterville and Graniteville area, the elementary school and Graniteville neighborhood, recreational and residential areas, and commercial and industrial operations.
The project was developed through the VTrans Local Transportation Facilities (LTF) Section and followed the LTF Guidebook. Professional services included project definition (purpose and need, project scoping, information gathering, public participation), right-of-way, utility considerations, final design and contract documents, and engineering services during bid and construction. Environmental documentation and permitting services included: Categorical Exclusion, Wetlands, Historical & Archaeological, Stormwater, NPDES, Corps of Engineers, Stream Alteration, and Act 250.
The design incorporated reuse and recycling techniques, avoidance of natural resources, and extensive alignment analysis. Bridges (90 and 60-ft spans) were used to span a large wetland and a stream. D&K advocated use of recycled steel beams for the longer bridge and adaptive reuse of a historic steel truss bridge for the shorter span, resulting in significant cost savings to the Town. Trees removed from the path during construction were ground on site and used for erosion control. D&K was proactive in right-of-way acquisition, engaging property owners through early and consistent coordination and informational meetings resulting in significant public and landowner support for the project. Work included property owner meetings, development of preliminary and final right-of-way plans, property appraisals, and assistance with review of right-of-way documents.
Gilford Sidewalk on Alvah Wilson Road
DuBois & King developed infrastructure improvements along Alvah Wilson Road, a project funded through a Transportation Enhancement (TE) grant. The focus of the project was to design and construct a 1,200-ft-long bituminous concrete sidewalk with a granite curb along the north side of Alvah Wilson Road, extending from Gilford Avenue (Route 11A) to Belknap Road. The sidewalk crossed the Gunstock River via an existing bridge. The new sidewalk connects the school system to the existing sidewalk system. Services include:
Site survey
Historical preservation
Conceptual, preliminary, and final design documents
Environmental permitting and NEPA clearances
Right-of-way documentation
Utility coordination
Construction bidding oversight and administration

Barre City Shared Use Path, Granite Museum Segment
DuBois & King conducted an alignment study and prepared conceptual level engineering plans for the first phase of the 1.6-mile-long shared use Granite Museum Segment, resulting in a preferred path alignment, preparation of conceptual level engineering plans, and execution of the required NEPA Categorical Exclusion document. The alignment established the basis for the subsequent design.
DuBois & King continued as the City’s consultant for design, permitting, and construction phase services. The path is designed to provide a source of outdoor recreation and an alternative commuter route, and to connect neighborhoods and businesses. The path is a 10-ft wide paved facility and includes two pedestrian bridges over the Stevens Branch of the Winooski River, as well as several retaining walls to support the path and adjacent side slopes. Interpretive stations are planned to highlight Barre’s rich history in the granite industry and to add interest for path users. The path is being designed to thread its way through a built-up urban area and will be located between the VT Route 62 corridor and adjacent neighborhoods and commercial businesses.
DuBois & King services include topographic field survey; identification and assessment of alignment options and environmental resources; preparation of conceptual, preliminary, and final plans and Categorical Exclusion documentation; permitting; right-of-way documentation and acquisition plans; preparation of contract documents; coordination with utilities, VTrans, and the Vermont Railway; landscape design; and design services during construction.
DuBois & King has actively participated in meetings with property owners, the City Council, the public, and the Barre City Bike Path Committee, and has provided support of the Bike Path Committee’s public outreach efforts, including preparation of quarterly newsletters and displays for local events such as the Barre Heritage Festival and first ever Barre Bike and Fitness Festival.
Bicycle and Pedestrian Facilities
DuBois & King’s bicycle and pedestrian facility design includes sidewalks, multi-use pathways, and on-road bicycle facilities. Planning and design experience includes fitting pathways into challenging urban areas with proximity to existing buildings and infrastructure, numerous street crossings, railroad crossings, utility conflicts, and property owner concerns. Rural pathway projects have involved addressing wetland impacts, cultural resource impacts, security and safety concerns, and maintenance.
Non-motorized enhancements have included the addition of exclusive and shared use bike lanes; the addition of pedestrian pushbuttons and signals; retiming of traffic signals to better accommodate pedestrians; installation of radar feedback signs; narrowing of travel lanes to provide wider shoulders and reduce vehicle speeds; installation of pedestrian signing and crosswalks; installation of textured crosswalks to improve visibility; the addition of lighting to improve safety; installation of landscaping to address property owners’ concerns; and the incorporation of amenities such as benches, bus shelters, and informational signs.
