SHELBURNE HULLCREST STORMWATER FINAL DESIGN
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.
- Worked with the Town to develop final designs and assist 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.
FEA staff supervising the installation of the Contech storm filter system.
Pre-cast flow splitter to allow for adjustable baseflow control to maximize phosphorus removal efficiency.
FAIR HAVEN VILLAGE GREEN STORMWATER DESIGN
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.
- Provided conceptual designs, final designs, bidding support, and construction oversight.
- 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.
Sierra Environmental Drilling collected soil cores to determine the depth to ground water (approx. 20 feet) and to verify soil suitability for infiltration at depths greater than traditional test pits.

POTASH BROOK MONITORING
2016 - Present
South Burlington, VT
Client:
City of South Burlington
Project Summary:
- 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 (USGS) 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.
- Developed phosphorus and chloride rating curves to allow for accurate estimation of total loading through baseflow and storm conditions.

OPTI POND 8
2020 - 2021
Burlington, VT
Client:
City of Burlington
Project Summary:
- In partnership with EcoSolutions, Inc., 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.

BOLTON VALLEY RESORT SAMPLING
2020 - 2021
Bolton, VT
Client:
Bolton Valley Resort
Project Summary:
- 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 three 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.
