2021 - 2025

Statewide, VT

Client: 

VT Department of Forests, Parks, and Recreation

Project Summary:

• FEA completed road erosion inventory assessments of forest roads, VAST trails, and State Park access roads on state lands.
• Completed 15,603 on-foot assessments of 100-meter road segments over the course of 3 field seasons.
• Each assessments included identification of water quality impacts on the given road segment and recommended acceptable management practices to bring the segment into compliance with the standards.

2022 - 2024

Bennington / Chester / Chittenden / Ludlow / Mendon / Pittsford / Pownal / Wilmington, VT

Client: 

VT Department of Environmental Conservation

Project Summary:

• FEA, in collaboration with SLR Consulting, completed stormwater master plans (SWMPs) for 8 Vermont towns.
• Over 200 stormwater problem areas were identified through field tours with Town representatives and local stakeholders.
• FEA developed 40 conceptual designs for high-priority problem areas across all of the Towns.

2022 - 2024

Barton, VT

Client: 

Greenprint Partners

Project Summary:

• FEA provided survey, permitting and designs of a gravel wetland to comply with the 3-9050 3-acre stormwater rule at the Lake Region Union High School. 
• Performed a topographic survey of existing conditions of the site and project permitting including a VT Dept. of Environmental Conservation (VTDEC) operational stormwater permit (9050). 
• Developed a gravel wetland design, meeting the Vermont Stormwater Management Manual Rule and Design Guidance.
• Provided bid process assistance and contractor selection, as well as construction oversight and project certification following implementation.

2022 - 2023

Windsor, VT

Client: 

Mount Ascutney Regional Commission

Project Summary:

• FEA provided survey, permitting and designs of a series of infiltration basins at the Mount Ascutney Hospital and Health Center. 
• Developed an infiltration basin design, meeting the Vermont Stormwater Management Manual Rule and Design Guidance.
• Provided bid process assistance and contractor selection, as well as construction oversight and project certification following implementation.

2022 - 2025

Shelburne, VT

Client: 

Town of Shelburne

Project Summary:

• FEA completed a phosphorus control plan (PCP) for the Town of Shelburne in 2021. The highest priority recommendation for phosphorus reduction was a retrofit to the existing underground chamber system at Hullcrest Park, which was installed to reduce peak flows in Bartlett Brook. 
• Worked with the Town to identify a range of retrofit options to provide cost-effective phosphorus removal, utilizing the existing stormwater infrastructure. A Contech proprietary stormwater filter system was selected as the best option. 
• Developed final designs and assisted with project bidding.
• The retrofit installation was completed in January 2025, providing approximately 12.4kg/year of phosphorus removal at a low cost/kg compared to other systems planned or installed within the Town.

2019 - 2025

Fair Haven, VT

Client: 

Poultney Mettowee Natural Resources Conservation District

Project Summary:

• FEA identified the Fair Haven Town Green as a potential location for a large stormwater infiltration chamber system while developing their  2018 Poultney River stormwater master plan. 
• FEA worked with the Poultney Mettowee Conservation District through conceptual designs, final designs, bidding, and construction. 
• The final design was sized to capture approximately 60% of the water quality volume from the 8.7 acres of impervious surfaces draining into the existing Town stormwater system along Caernarvon Street. 
• A large underground infiltration system (Ferguson R-Tanks) with a Contech pre-treatment swirl separator was installed in 2025. A diverter was installed in an existing catch basin to direct the design flow across North Park Place to the new infiltration system. The system is functioning well and reducing nutrient and sediment inputs to the Castleton River.

2016 - Present

South Burlington, VT

Client: 

City of South Burlington

Project Summary:

• FEA worked with the City of South Burlington on a range of water quality monitoring projects on Potash Brook for over 10 years. Many of these monitoring projects were located at the former US Geological Survey monitoring station located at Queen City Park Road. 
• In partnership with Stone Environmental, developed a continuous streamflow monitoring station in 2016, which provides detailed rating curves across a wide range of flows. This station received additional instrumentation to monitor turbidity and conductivity to assist with the phosphorus TMDL and upcoming chloride TMDL compliance. 
• The data from this station helped develop phosphorus and chloride rating curves to allow for accurate estimation of total loading through baseflow and storm conditions.

2020 - 2021

Burlington, VT

Client: 

City of Burlington

Project Summary:

• In partnership with EcoSolutions, Inc., FEA worked with the City of Burlington to install a proprietary stormwater control system to maximize the storage and treatment volumes within an existing pond (Pond 8) to reduce peak flows within the Englesby Brook watershed. 
• The pond was drained so the existing outlet structure could be retrofitted to install a low orifice (8 ft lower) which is controlled by a remotely operable butterfly valve through the Opti software. 
• The installation also included large solar panels, valve controls, control panels, a tipping bucket, and a pressure transducer.

2020 - 2021

Bolton, VT

Client: 

Bolton Valley Resort

Project Summary:

• FEA assisted Bolton Valley Resort with water quality monitoring to support their 10-year master plan effort. The plan requires establishing a water quality baseline prior to planned expansion.
• Worked with VTDEC to identify 7 monitoring locations on Joiner Brook and 3 tributaries to best capture water quality impacts associated with the Resort and establish reference conditions within the same drainage areas. 
• Collected baseflow and storm event water quality grab samples and collected macroinvertebrates following VTDEC methods. 
• FEA will continue sampling these sites annually as the planned expansion activities progress.
