Weston ZBA presses 518 South Ave developer for missing engineering detail

WESTON — June 8, 2021 — Weston ZBA presses 518 South Ave developer for missing engineering detail on 200-unit 40B. Peer reviewer Mark Bartlett of PSC Inc. delivered a 13-page, 40-comment memo flagging missing pipe sizes, pump-chamber specs, fire-flow testing, a photometric plan and ADA certification, while colleague Tom Houston said 25 of 65 stormwater comments remain open and the town's regulations require a net reduction in runoff volume that current modeling shows a 84 percent increase at one 100-year-storm design point. Hydrologist Scott Horsley told the board the proposed 38,000 gallons-per-day wastewater discharge is roughly 10 times the adjacent stream's 3,800-gpd summer baseflow and would push nitrogen and phosphorus past EPA ecological thresholds. Town Counsel John Witten of KP Law told the applicant that "absent a waiver, the applicant must comply" with local rules. The board, chaired by Jane Carlson, continued to June 30 at 7 p.m.
