Board continues review of 19 Main Street mixed‑use proposal; applicant to submit building elevations and lighting

The Planning Board continued the site‑plan review for 19 Main Street on Aug. 14 after outstanding engineering and architectural items remained under review.

Applicant representatives submitted multiple plan sets and responses to peer review, and the board’s consultant identified two substantial remaining items during the second peer review: groundwater separation / groundwater mounding calculations for the proposed subsurface infiltration system and documentation of stormwater pollution prevention controls that must be finalized prior to construction. The peer reviewer requested site‑specific soil log data and an initial saturated thickness (ESHGW) be used in the groundwater calculations; the applicant reported the team revised the calculations using an 11.5‑foot initial saturated thickness and adjusted pipe routing to reduce mounding in the critical area.

Board members and the planning consultant also asked the applicant to provide architectural building elevations, a photometric (lighting) plan showing any potential light trespass onto adjacent properties, and a detailed planting/landscape list (peer reviewer recommended native species). The applicant said mass DOT permitting remains pending and that the site will require a final SWIP and illicit discharge plan to be submitted as a condition prior to construction.

Because several items remained for peer review and the consultant had not been contracted to review the applicant’s third set of revisions, the board continued the public hearing to Sept. 11 and requested the outstanding material — building elevations, the photometric plan, a planting schedule and any mass DOT coordination materials — be submitted in advance so staff and peer reviewers can prepare conditions of approval.
