Wells planning board continues Mia Lane subdivision workshop after stormwater, well and buffer concerns

The Wells Planning Board continued a workshop on the proposed Mia Lane Subdivision on Monday, taking public comment on stormwater and fire-protection arrangements and voting to continue the file for up to 60 days.

Resident Jean Hill urged caution over stormwater and the subdivision’s drainage design, telling the board, “Given the ongoing and worsening impact of our more frequent and intense storm events, it is critical that the hydroclad model function as intended.” She questioned runoff reaching a culvert near 64 Autumn Lane and objected to relying on a private hydrant in the Sea Orchard homeowners association for fire protection.

Mike Sudak, the project engineer representing Gilchrist Development, said the developed grading will direct runoff into a single detention pond and reduce peak flows compared with existing conditions. “The site drains almost perfectly in half,” Sudak said, describing roadside and rear-yard swales that feed a detention feature designed to attenuate flows before they reach the culverted crossing at Autumn Lane. Sudak also said armored slopes and inlet/outlet protection will be used where grassed swales are not feasible.

Why it matters: Board members said the site’s tight geometry, proximity to neighbors and the reliance on drilled private wells for water require clear conditions before moving to construction. The board and applicant discussed both on-site private wells and the cost of extending municipal water lines; an engineer’s estimate placed a municipal extension in the high five figures versus a much lower cost for private wells.

Key developments and board action - The board reviewed and approved a set of buffer and screening details recommended in staff memos: a 25-foot buffer along Teresa Lane, 25-foot buffers on the north and south sides with a recommended 6-foot fence or plant material, and an entrance buffer planted at 8 feet on center with a minimum 6-foot specimen height. The board required plantings to be in place prior to the first building permit. - The planning board voted unanimously to continue the Mia Lane workshop for up to 60 days. - The board asked the applicant to provide well-yield and water-quality testing prior to a preconstruction meeting; Sudak and board members agreed a pre-construction condition demonstrating adequate yield/quality for proposed private wells would be necessary if the board allowed wells instead of extending municipal water.

Applicant response and outstanding items - Sudak said one previously raised public concern — whether riprap or vegetation should be used — was limited to armored emergency spillway areas and inlet/outlet protections; most slopes will be grassed. - The project proposes six condominium dwelling units on a roughly 3.5-acre parcel, a private road about 550 feet long, on-site stormwater detention, and private drilled wells; the applicant noted no wetland impacts were proposed. - The fire hydrant on Autumn Lane that Jean Hill referenced is a private hydrant serving the Sea Orchard HOA; Sudak said staff requested it be shown on the plan, but the application does not propose an access easement and the applicant did not commit to any formal shared-use agreement. Sudak noted state law gives fire departments broad authority to use water sources in emergencies.

Board expectations and next steps - The board asked the applicant to: (1) provide well test yield and quality results for proposed lots or otherwise demonstrate why a municipal water extension is financially unreasonable; (2) show buffer and planting details on revised plans; and (3) add deed or HOA language (if the board and applicant agree) to limit accessory dwelling units (ADUs) or short-term rentals if the project intends to restrict them. - The workshop was continued; the board will reconvene with the updated plans, the well-test information if it is available, and finalized deed/HOA language if the applicant elects to include no-ADU/no-short-term rental restrictions.

Ending: The board closed the public hearing earlier in the meeting and emphasized the project must meet the town’s stormwater and buffer requirements before building permits are issued; the continuing workshop will let staff and engineers resolve outstanding plan notes and the water-source determination.
