Cambridge Planning Board reviews draft Open Space and Recreation Plan; votes to send board comments to state

Cambridge Planning Board members reviewed a draft update of the city's Open Space and Recreation Plan on Feb. 25 and voted to transmit the board's comments to the Massachusetts Department of Conservation and Recreation for inclusion with the city's pending state submission.

The plan, presented by Daniel Mesplay, Director of Community Planning and Design at the Community Development Department, lays out a seven-year vision (2023—20230), maps of open-space access and need, and a set of strategies to guide park investments, resilience measures and equity-focused programming. The staff said completing the state-required plan update would make the city eligible for state grant funding for parks projects.

Mesplay and his team described a multi-pronged analysis that combined acreage, walk-shed access, climate resilience indicators, public-health data and demographic factors into index maps identifying areas of compounded open-space need across Cambridge. "The core benefits to doing this is that it makes the city eligible for state grant funding for our parks projects," Mesplay told the board. Staff described the resulting composite map as a tool to prioritize interventions where combined needs are greatest, while noting it does not mean other neighborhoods lack needs.

City staff said the draft documents are posted on the city website and that they expect to submit the final materials to the state in early to mid-March. Presenters emphasized community engagement: the plan builds on the Our Parks Our Plan outreach process (begun in 2021) and on other city efforts, including the urban-forest and climate-preparedness work, and will be used to inform development review and capital planning.

Key findings and strategies presented to the board included: - Inventory and access: Cambridge has just under 500 acres of public open space, representing roughly 12% of city land area. Staff reported that nearly the entire city population is within a ten-minute walk (about a half mile) of some public space, although types and sizes of spaces vary and not all areas provide equivalent park acreage per resident. - Composite indices: Staff combined multiple data layers (access, resilience, public health and community characteristics) into topic-specific indices and a composite open-space-need map to highlight neighborhoods where needs compound. - Design and programming strategies: Recommendations include using right-of-way space for plazas and pocket parks, redesigning park renovations to advance resilience and equity, targeted tree-planting and stormwater features, activating privately created public spaces, and continuing acquisition efforts where feasible (staff said acquisition is a longer, less predictable pathway). - Community engagement and equity: Presenters emphasized tailoring outreach to reach underrepresented groups and using park projects as opportunities for community partnership and activation.

Board members asked how the indices were weighted, how use of parks is tracked, and whether the plan will be used to guide capital and programming priorities across departments. Gary Chan, neighborhood planner, and Daniel Mesplay said the indices were informed by community feedback and that an appendix documenting methodology and the weighting approach can be provided. Staff acknowledged that some types of park use (permits, organized programs) can be quantified, but everyday informal use is harder to measure systematically. Mesplay and staff said they coordinate with other departments (DPW, Recreation, urban forestry and others) and with regional/state partners on projects that cross departmental or jurisdictional boundaries.

Several board members urged clearer executive summaries and map legends in the final report to make the findings more accessible to nontechnical readers. Members also suggested adding future-growth projections (for example, in areas affected by recent multifamily zoning changes) as an additional layer to help prioritize park investment where residential capacity is increasing.

After the presentation and questions, the board voted to conclude the discussion and asked staff to draft and transmit a comment letter to the state agency. The motion to conclude discussion and transmit comments was moved by Diego Macias and seconded by Ashley Tan. On a roll-call vote the four full board members present voted yes: Ted Cohen, Diego Macias, Ashley Tan and Chair Mary Flynn. The motion passed.

Staff said they will compile the Planning Board's comments into a letter for transmission to the Division of Conservation Services within the Department of Conservation and Recreation as part of the city's state submission, and that they expect the final submission to the state in early to mid-March.

The board's discussion and the staff presentation will be summarized in the letter that accompanies Cambridge's draft Open Space and Recreation Plan when it is submitted for state review.
