The meeting saw Donna McKenzie, the citizen petitioner, and Dr. Roger Luman, a public health expert, present a detailed case for the moratorium. McKenzie introduced two motions—one legally binding and another advisory—arguing that a pause on new artificial turf projects would allow time to thoroughly evaluate the associated risks. She highlighted concerns about the materials used in artificial turf, including chrome rubber infill, which is known to contain lead, and raised alarms about PFAS, for which there is no safe exposure level according to the Environmental Protection Agency (EPA).

Dr. Luman reiterated these concerns, citing studies that link artificial turf to significant microplastic pollution. He described how physical stressors, such as athletic activities, cause the plastic blades of turf to deteriorate, releasing microplastics into the environment. He noted that artificial turf is a major contributor to urban microplastic pollution, which can affect drinking water and food sources due to bioaccumulation in fish.

The debate over artificial turf extended into discussions on its lifecycle and disposal challenges. Artificial turf is non-biodegradable and often ends up in landfills, raising further environmental concerns. The commission was urged to consider alternative options, such as natural grass or hybrid turf, which offer several environmental benefits despite being more labor-intensive to maintain.

Some participants argued that previous efforts to engage stakeholders had not resulted in significant dialogue, and they suggested the moratorium could facilitate necessary conversations about the future of community athletic fields.

In addition to the artificial turf debate, the commission addressed the future of the Johnson School property. Discussions centered on preserving open space amid potential redevelopment plans. Members expressed a desire to maintain the integrity of existing green spaces and emphasized the importance of community involvement in shaping the property’s future. The property’s historical significance and its role in mitigating heat in densely populated areas were highlighted as key considerations.

The commission also tackled a property boundary issue involving a fence encroaching on town land. Members expressed concerns about setting a precedent for private property extensions onto public land, emphasizing the importance of adhering to property regulations.

In another segment, the commission evaluated a tree replacement proposal linked to a development project. Concerns were raised about the adequacy of the proposed mitigation measures, particularly regarding the financial compensation for tree removal and the geographic proximity of replacement efforts.

The meeting also featured updates on open space and accessibility initiatives, such as plans for a fully inclusive park and playground by 2027, and efforts to align Natick’s open space and recreation plan with new state guidelines. Emphasis was placed on engaging underrepresented communities and utilizing community preservation funding for large-scale projects.
