House addition NOI in Woburn includes geothermal borings and stormwater upgrades; commission reviews long‑term controls
Summary
Oxbow Associates presented updates for Scott Hamilton’s house addition: two small deep geothermal borings, larger biodegradable wattles, riprap at overflow locations and an infiltration system designed to meet ORW Standard 6; commissioners asked about long‑term pollution prevention and timing of future specs.
A representative from Oxbow Associates described updates to a Notice of Intent for a house addition on Oct. 10, telling the Woburn Conservation Commission that the revised plan now includes a footprint for a small residential geothermal system, additional erosion controls and riprap details at downspout overflows and the deck.
Kyle Cormier said the geothermal component will consist of two small, deep borings (2–3 inch diameter) with no permanent surface equipment beyond a small pipe stub that ties into the house. He said the engineered stormwater infiltration system is sized to hold a 100‑year storm event and that riprap placed at potential overflow points is intended to prevent sediment conveyance into the nearby ORW. The representative added that changes to wattle size (now 12 inches) and the switch to a biodegradable material were made to improve erosion control during construction.
Commissioners sought clarification on the long‑term pollution prevention plan and whether controls are perpetual or tied to project closeout; the applicant said the plan appears to be intended to remain in place for the life of the system, with final closure conditions determined as part of commission oversight. Commissioners also asked that the applicant notify the commission before beginning geothermal work and provide detailed specs and exact boring locations at a later date. The hearing was closed and staff noted the commission has 21 days to issue a decision.
No final determination text appears in the transcript; the commission indicated it would issue a written decision within its standard period.
