Concord planning board proposes broader shared-parking rules, removes 50% cap

The Planning Board on April 9 presented a warrant article to allow broader use of joint (shared) off‑street parking in commercial districts and to replace the bylaw’s arbitrary 50% minimum reduction with a data‑driven, hour‑by‑hour parking demand analysis.

The change matters because it would let a wider range of permitted businesses — not just banks paired with retail or office uses — apply to use the same off‑site parking, subject to analysis and planning board review. Planning board presenter Mark Giddings said the amendment is intended as a “very, very minor change” to make the bylaw fit modern business patterns while protecting public safety and neighborhood welfare.

Under the proposal, a joint parking request must include an hour‑by‑hour demand analysis using industry sources such as the Institute of Transportation Engineers’ Parking Generation manual or comparable empirical data judged satisfactory by the building commissioner. The planning board may require an independent transportation engineer, hired by the town and paid by the applicant, to peer‑review the analysis. The minimum required off‑street parking would equal the largest number of spaces required at any single hour shown in the analysis. Giddings underscored that planning staff must approve documentation that “parking will remain adequate following occupancy” and that any long‑term lease for off‑site parking must be executed by all owners and tenants.

Speakers at the hearing pushed on enforcement and unintended consequences. Carol Savoy asked whether the change would apply to residential or mixed‑use properties; presenters said the amendment targets commercial/business uses only and would not automatically apply to residential parking. Several residents, including Connie Levine and William Andrews, pressed on how, in practice, a joint‑parking approval could be rescinded if parking later proves insufficient. Giddings and other planning board members said the bylaw retains language allowing rescission if joint use creates a public nuisance or adverse impact, and that written agreements and site‑plan approval would be required before occupancy. Select Board chair Mary Hartman asked presenters to front‑load the public presentation with a clear statement of the problem the amendment intends to solve; presenters agreed to add that material and to post the slide examples online.

Why it matters: supporters said the change could reduce unnecessary pavement, lower developer costs, and help keep storefronts viable; critics warned it could open a pathway for developers to avoid providing on‑site parking or create cumulative parking stress if adopted without a comprehensive townwide parking study.

The Planning Board framed the amendment as a targeted tool — not a wholesale rollback of parking standards — and said site‑plan review, written agreements, and potential town‑hired peer review will provide oversight. The public hearing closed without a final vote; the board will include the amendment as a warrant article at Town Meeting.

Ending: The board plans to post the presentation slides and the hour‑by‑hour example analyses online, and to keep the joint‑parking language under review as related zoning proposals move forward.
