Development – DuBois & King, Inc.

Eastman East Lake Road Drainage

The Eastman Community Association (ECA) selected DuBois & King to assess existing conditions (including stormwater patterns, drainage infrastructure, erosion areas, roadway conditions and subsurface conditions) to evaluate stormwater quality, erosion and roadway improvements to mitigate water quality impact to Eastman Lake. Located within the sub-association of the Eastlake Condominium Association (ELCA), DuBois & King collaborated with both stakeholders on developing improvement alternatives. The engineering study discussed roadway surface, stormwater collection and stormwater treatment options enhance water quality discharging to the lake. An engineering study recommending the preferred alternative, project phasing and anticipated construction costs has been approved by the ECA and ELCA project committee. A Public Hearing is scheduled to receive public feedback that will ultimately lead to the design/development phase of the project.

Construction of the recommended improvements are scheduled to be completed Summer 2017. DuBois & King staff are providing hydraulic and hydrologic (H&H) analysis, drainage system design, geotechnical engineering, wetland delineation, survey, and permitting assistance to advance the project from study phase to design phase and though construction.

Stowe Mountain Lodge

Civil services for new 139-unit, luxury, 4-star resort building at Spruce Peak Mountain Village. The project included six levels of whole-ownership and fractional-ownership units on a five-acre site adjacent to the Spruce Peak ski area. A luxury spa was included as a key amenity. Underground parking was developed to serve the project.

Professional Services

Services included design of grading, paving, stormwater management, water and wastewater systems, and erosion prevention and sediment control systems for the site. Design of site improvements required close coordination with the Spruce Peak Master Plan requirements. Erosion control was critical on the project as it is located in a mountainous terrain in close proximity to streams. The stormwater management system included a Vortechnics chamber to provide water quality treatment and a subsurface infiltration gallery to provide retention and groundwater recharge.

Grading at the site was challenging, as the building was required to blend into the forested hillside, while providing for convenient vehicle and pedestrian accessibility, including ADA access. Clearing limits established during the permitting/approval phases of the project resulted in constraints to grading that required creative use of slope stabilization and retaining walls. Close coordination with other project team members, including the owner, landscape architect, and permitting approval agencies, was critical to developing the project successfully.

Top Ridge Development

Civil/site design for Top Ridge development, an existing development of single-family and duplex-style homes. Permit application and Erosion Prevention and Sediment Control (EPSC) Plan for the construction of Units #30, 31 & 34 – 39. Project involves site work for an existing duplex construction of eight duplex style buildings near upper end of Glissade Drive, each with an approximate footprint of 2,025 square feet and a small parking area. Two driveways (approximately 450 and 300 feet long) provide access from Glissade Drive to the parking areas in front of the units. Additional construction activities include realignment of upper portion of Glissade Drive, installation of water & sewer utilities, side slope grading, retaining walls, driveway culverts, an overflow parking area, and stone-lined ditches.

Construction services for stormwater basins and associated inlet and outlet channels, as part of the overall project’s stormwater management plan and were constructed during the summer per an agreement with the ANR Stormwater section.

Green Mountain Stock Farm

Site planning, permitting assistance, design, and cost estimating for a 78-lot subdivision including the restoration of a 100-year-old historic farmstead into an Inn and Restaurant. Designed the roads, pathways, and drainage system; water supply, storage, and distribution system; wastewater and storm runoff management systems; also responsible for the overall coordination, preparation and presentation of evidence in securing the State Land Use Permits (Act 250) for the projects. A deer winterizing/Forest Management plan was developed as part of the Act 250 process.

Partridge Farms

Planned residential development consisting of 37 single-family units and 104 multifamily units, an existing 30-unit mobile home park, and a future commercial development on 165 acres. Services included surveying, planning, site engineering, assistance with approvals and permits (water and wastewater permits and State Act 250 Land Use Permit), and construction phase services. Provided plans and specifications for construction of site improvements consisting of earthwork, site drainage, roads, parking, water system, wastewater system (including a pump station), and erosion control.
