Planning board approves subdivision at 548 South Street with conditions, waivers

The Bridgewater Planning Board on July 15 approved a continued definitive subdivision plan for 548 South Street (Map 61, Lot 121), concluding a multi-month review with a 4—0 roll-call vote.

The board's decision followed a presentation by Larry Silva of Silver Engineering, who asked the board to close the public hearing and approve the plan after submitting revised plans and correspondence. "We've addressed all comments from staff," Silva said, adding that the alignment with South Drive does not, in his view, require the regulation waiver the application listed. The board heard technical input from the town engineer, Greg Tansey, and planning staff while abutters raised concerns about trees, traffic, and drainage.

Why it matters: the proposal divides the property into four lots, three of which would rely on on-site septic and private wells; the board focused on nitrogen-aggregation rules under Title 5, the location and maintenance of a detention basin shown on Lot 3, and easement language to ensure long-term maintenance and tree preservation.

The board placed multiple conditions on the approval. Members agreed that any lot release will require an established homeowners association with maintenance responsibilities and an easement enabling access from the cul-de-sac to the Lot 3 detention basin. The board also required a written nitrogen aggregation plan (with deed-restricted limitations on nitrogen-producing activities) be submitted to the Board of Health and DEP and provided to the planning board before any lot release. The town engineer emphasized that, as presented, the basin on Lot 3 was required to meet the subdivision's pre/post BMP Standard 2 calculations, unless the applicant provides calculations demonstrating an alternate compliance approach. "The basin on Lot 3 is part of the subdivision's hydraulic analysis," Tansey said.

Public comment: an abutter, identified in the record as Mrs. Lefebvre, pressed the board on whether Lot 3 had conservation approval and warned that proposed roadway grading could destabilize large trees near the property line. The applicant said trees were shown to remain and that grading for the swale would involve only the first 18 to 24 inches of surface grade; the board requested tree-preservation language and a combined drainage/tree easement in the recorded plan.

Next steps: the board's chair said staff would draft a decision letter capturing the conditions and circulate it to members before final signature; the planning board emphasized that the nitrogen-aggregation plan and deed restrictions must be completed before any lot releases.
