ZBA approves Silver Lining Development’s Linton Street shared driveway with Conservation Commission stipulations
Summary
After revisions reducing buffer impacts and adding porous pavement and a maintenance easement, the ZBA approved Silver Lining Development’s request to impact approximately 6,050 sq ft of wetland buffer for a private shared driveway to enable three future lots; the board adopted several Conservation Commission stipulations as conditions of approval.
The Nashua Zoning Board of Adjustment approved a wetland special exception for Silver Lining Development LLC to impact approximately 6,050 square feet of wetland buffer to construct a private shared driveway and associated site improvements for three proposed single‑family lots off Linton Street.
Attorney Andy Proben and project manager Ethan Beals described revisions made after Conservation Commission review, including reducing buffer impacts, removing impervious surface from the buffer, using porous pavement for the driveway, regrading to avoid a retaining wall, and an easement that requires ongoing maintenance of stormwater features. Beals said about 82% of the proposed buffer impacts fall within existing disturbance or an existing sewer easement.
Beals presented a stormwater summary showing post‑development detention and treatment (porous pavement and BMPs) that, in his analysis, reduces peak runoff rates compared with current conditions. The applicant offered a draft recorded easement obliging long‑term maintenance and replacement of porous pavement and drainage elements.
Conservation Commission had issued an unfavorable recommendation citing tree loss and other concerns, but included six stipulations the applicant agreed to address. Board members praised the redesign and the added stormwater controls and voted to approve the special exception with the Conservation Commission stipulations incorporated into the approval.
What’s next: The project must satisfy recording of the maintenance easement, conform to the stipulated revegetation and invasive species removal plan, and proceed through subsequent planning and public‑works approvals before construction of the shared driveway and subdivision work.
