Planning board approves 10-bay aircraft hangar for lease area at Concord Municipal Airport

The Concord City Planning Board approved on April 21 a major site plan and architectural design review for a new 11,550-square-foot, 10-bay aircraft hangar in Development Lease Area DZ-4 at the Concord Municipal Airport.

The applicant, Hampshire Aviation LLC, presented a prefabricated metal 10-bay hangar building arranged in T-hangar configuration with ten tied parking spaces and one ADA-accessible stall. The hangar will be within an airport development zone already designated for aviation uses; staff noted a survey discrepancy between recorded lease-line mapping and an access easement through an adjacent commercial property, and the city and applicant agreed to memorialize a lease-line adjustment by memorandum of understanding or other recorded instrument before final recording. The project was reviewed for endangered-species and conservation lands bordering the airport; staff reported the city has coordinated with New Hampshire Fish and Game and U.S. Fish and Wildlife and planned the required memorandum of understanding to meet conservation and development-agreement requirements.

Because the site is constrained and surrounded by conservation lands, the applicant requested waivers to not require architect-signed elevations and to not show a scale bar on building elevations — staff supported those waivers and the board granted them. The board also granted a conditional-use permit to reduce a two-way driveway width from the standard 24 feet to 18 feet because the proposal’s constrained site and the airport-only access route make the narrower drive appropriate; the board required signage and a fire-department-approved emergency-access system.

Planning staff said the proposed development must still satisfy precedent conditions including a revised lease-line plan or memorandum, technical appendices, and final recorded documents required by the city solicitor and planning staff before permits are issued. The board approved architectural review and site plan approvals with the revised precedent conditions.

Why it matters: The hangar expands based aviation capacity and private hangar leases at the municipal airport, and the project required coordination between airport lease management, conservation agreements and the planning division to ensure development occurs in the proper leased area without harming adjacent conservation-managed land.

What’s next: The applicant will record the lease-line adjustment memo or plan and deliver the other precedent documents; staff will clear precedent conditions and record the final plans ahead of building permit issuance.
