Planning Board reviews draft citywide urban design guidelines; staff schedules public open house

City staff and consultants presented a draft set of citywide urban design guidelines to the Cambridge Planning Board on March 18, and invited board input before a public open house and exhibition the following week.

Susanna Bigelow, an urban designer in the Community Development Department, introduced the project and said staff and the consultant team had worked across departments and stakeholders to craft guidance intended to shape future development and public projects. “Urban design guidelines are very important to Cambridge’s quality of life,” she told the board, framing the document as a flexible, evolving resource to guide buildings, open spaces and streetscapes across the city.

Rami El Samahi, principal at the consultant firm OverUnder, described the draft’s organization and the process used to create it. The document is organized into four core chapters — context and site, buildings, open space and streetscapes — and articulates three goals (design excellence, equity and sustainability) and six core values (inviting, eclectic, contextual, connected, adaptable and healthy). El Samahi said the project team reviewed nearly 50 other guideline sets, conducted public‑space observation and met frequently with city staff and stakeholders over an 18‑month period.

The draft is intended as nonbinding guidance to inform advisory design consultation and design review processes; the project team said it may prompt zoning updates where specific regulatory changes are needed. The team noted near‑term next steps: a public open house scheduled for the week after the March 18 meeting, an exhibition at the main branch of the public library and a plan to revise the draft based on public feedback with the aim of completing a revised document by mid‑ to late‑April.

Board members and the consultant team then discussed the draft at length. Key themes raised by board members included:

- Hierarchy and context: Tom Sinovich asked whether the document should apply a hierarchy that prioritizes some guidelines over others. Staff and the consultant team said the guidelines are intentionally flexible because what should be prioritized depends on project scale and location; Daniel (staff) added that the document does embed internal hierarchies within each chapter (principles, experience, element/typology). Several board members agreed context should guide how the guidelines are applied.

- Climate and resilience: Several members — including Sinovich and Chair Mary Flynn — urged greater emphasis on climate resilience and on giving nonnegotiable weight to strategies that address heat, flooding and long‑term environmental risk. Flynn said resilience is not optional and should be treated with higher priority in practical application.

- Applicability to smaller residential neighborhoods: Board member Dan Anderson asked whether the guidelines augment or would be reconciled with Article 19 (the city’s zoning design objectives and building/site plan requirements) and whether additional guidance is planned for multifamily upzoning areas and smaller residential streets. Staff said the document does not replace Article 19; CDD will evaluate whether zoning text changes are needed. Staff also said separate, more targeted guidance on multifamily housing and neighborhoods is forthcoming.

- Document structure and usability: Several members praised the document’s thoroughness and visual presentation while recommending clearer navigational tools (diagrams, summaries, or searchable indexes) to help users find the most relevant guidance for a specific project or context. Board members suggested making sidebars and cross‑references easier to use and adding more Cambridge‑specific photographic examples while retaining inspirational international precedents.

- Seasonal and experiential contexts: Planning Board member Ted Cohen urged the team to account for how people experience the public realm at different speeds and seasons — including vehicle views and winter conditions — and recommended clearer guidance on lighting, durable materials and roof/wind/utility screening.

The meeting drew a short public comment period. Speakers who addressed the draft included Gordon Moore, who called the document “a beautiful document” but urged greater attention to sunlight, air and the impacts of taller facades in Cambridge’s dense neighborhoods; Suzanne Blier, who asked the board to add criteria addressing single‑family and small multifamily houses and scale transitions; Marilee Meyer and Marissa Coccio, who asked for guidance that protects smaller neighborhoods and streets now likely to see change under recent zoning; and James Zall, who urged the board to frame guidance in the context of housing needs, climate and equity rather than use guidelines to simply preserve the status quo.

After discussion the full board voted to conclude the item’s discussion. Diego Macias moved to conclude; Tom Sinovich seconded. A roll‑call vote of the five full members present — Ted Cohen, Mary Lidecker, Diego Macias, Tom Sinovich and Mary Flynn — was recorded in favor; the motion passed.

What’s next: the city will hold an open house the week after the meeting and publicly post the draft at an exhibition in the Cambridge Public Library; the project team will collect public input and prepare a revised draft for staff review and potential zoning follow‑up. The team reiterated that the guidelines are intended to evolve over time.
