Consultant outlines mixed‑use bylaw rewrite; Planning Board to hold public workshop June 17

The Planning Board discussed an analysis and question set from consultant Emily Ennis of Ennis Associates on April 24 as the start of a multi‑stage rewrite of the combined business/residence (mixed‑use) zoning section (4.2.03). Ennis said she will draft ordinance text after the board clarifies policy choices and public priorities, and the planning team plans a public meeting on June 17 to solicit broader input.

Why it matters: The combined business/residence bylaw governs where and how mixed‑use development can occur in Concord’s village and limited business districts. Changes could affect whether new residential units are allowed above or behind commercial uses, the town’s affordable‑housing thresholds, design standards for open or green space, and the menu of waivers or incentives offered to developers.

Key questions raised: Ennis asked the board whether the bylaw should continue to require residential units be structurally part of the commercial building (common walls, foundation, roof and floor) or allow residential in separate buildings on the same parcel; whether the current affordable housing trigger (written as 20% but functionally counting rounded thresholds at four units) discourages smaller mixed‑use projects; and whether the bylaw should replace a complex “open space” requirement with clearer green‑development standards for stormwater, heat‑island reduction and public accessibility.

Board members and staff discussed tradeoffs between preserving active ground‑floor street life (for village districts such as West Concord) and making the bylaw flexible enough to encourage new housing. Ennis noted options the board could use if it wants to tie development flexibility to public benefits: for example, offering modest height or parking relief in exchange for affordable units, or offering a menu of benefits that a developer can select from to unlock certain dimensional bonuses.

Ennis said she will draft ordinance language after incorporating the board’s feedback and suggested the June 17 meeting focus on a small number of targeted questions (geography of the use, affordability thresholds, and green‑space goals). Several board members asked staff to consult the MBTA Communities economic feasibility analysis and other example jurisdictions to test thresholds and incentives for smaller‑scale mixed‑use projects.

Next steps: The consultant will prepare draft zoning text and materials for a public meeting on June 17; staff and the board plan targeted outreach and examples (photos, polls) so residents can compare design alternatives and state tradeoffs during the public session.
