Commission approves remediation and mitigation plan, issues order of conditions for 331 Hudson Road

The Town of Sudbury Conservation Commission issued an order of conditions for a continued Notice of Intent for 331 Hudson Road, approving a plan that revises driveway geometry, removes outbuildings and adds plantings and mitigation areas in the riverfront and buffer zones.

The applicant’s representative, Montgomery (of record as Montgomery Wustemski McNary of Acton), described plan changes that included a revised turnaround and removal of existing storage buildings, new tree plantings placed about 15 feet from a proposed addition, and loaming and seeding in the restored areas. He said the design keeps the project at or under the commission’s 5,000-square-foot approval limit.

Laurie, conservation staff, said the chart showed the project at exactly 5,000 square feet, which is the upper limit the commission can approve, and asked for confirmation that native seed mixes (not lawn seed) would be used in loamed-and-seeded areas. She also advised the commission on a special condition requiring demarcation of the mitigation areas with a clear planting edge so future owners and contractors can identify the restoration footprint.

During public and commissioner questioning, the applicant confirmed the driveway will remain gravel (not permeable pavers) and that the revised plan reduces driveway footprint by about 310 square feet. Commissioners discussed mitigation elements, including converting more than 1,300 square feet of existing lawn to native planting, removing two outbuildings and routing roof drains to a drywell to offset added impervious area from the proposed addition.

The commission voted to issue the order of conditions as drafted by staff, with the special condition requiring clear demarcation of restoration boundaries. Laurie will follow up with the applicant on administrative steps and signature requirements.
