Planning Board approves expansion of auto inventory area for Capital City Subaru on Manchester Street

The Concord City Planning Board approved April 21 a major site plan for expansion of vehicle display and inventory storage at 150 Manchester Street (Capital City Subaru), granting waivers for elements of the site-plan rules and a conditional-use approval to exceed 15% impervious surface in the aquifer protection district.

Project representatives from Northpointe Engineering described the proposal to enlarge the inventory area on the Integra Drive portion of the property, add an internal access connection, construct a larger stormwater detention basin sized for potential future expansion, and add landscaping along the new pavement edges. Staff told the board the application was largely complete and staff recommended approval subject to precedent and subsequent conditions, including standard easement language to protect the city’s access requirements and technical sign-offs.

The board approved architectural design review for the new paving and landscaping, denied certain waiver requests that belonged to variance processes rather than waiver authority, and granted a set of other waivers tied to RSA and site-plan criteria. The board also approved the conditional-use permit required because the expansion is partially within an aquifer-protection area and would render more than 15% of the lot impervious; staff said the project meets the ordinance standards with the proposed stormwater treatment.

Why it matters: The site is a visible commercial corridor near Manchester Street; the plan moves inventory storage out to a portion of the lot while adding stormwater infrastructure sized for future expansion. Approvals included technical precedent conditions to protect aquifer and municipal stormwater systems.

What’s next: Applicant must satisfy the precedent conditions in the packet (including documentation of drainage connections and any required easements) and then obtain construction permits.
