Public commenters contest Palo Alto turf study; advocates urge organic‑care alternatives and firms tout recyclable, PFAS‑free synthetic turf

Palo Alto — The Parks and Recreation Commission on Aug. 26 received public comment on a draft turf study but postponed the staff presentation to a special meeting; commenters offered sharply different technical views about artificial turf, microplastics, PFAS and whether improved organic grass management can meet community demand.

Manny Diaz, a consultant for TenCate Grass, a turf manufacturer, told commissioners that modern artificial systems address several commonly cited problems. Diaz said TenCate’s products can be recycled, that a PFAS‑free product (“Pivot”) is commercially available, and that well‑engineered artificial turf reduces long‑term operating costs compared with high‑use natural fields. Diaz provided the commission with technical materials and asked staff to examine newer product options and end‑of‑life recycling practices.

Several other speakers disputed the study’s implied conclusion that synthetic turf is the only option for high‑use fields. A number of commenters — including field managers and a soil scientist cited in public submissions — said the consultant report omitted examples of organically managed grass fields that have sustained much higher annual play hours than typical conventionally managed fields. One speaker cited case studies in which reconstructed or organically managed fields reported more than 2,000 playable hours per year and argued the consultant had not examined such approaches.

Neighbors also raised operational complaints about existing synthetic installations: one resident said older synthetic fields at Coverley shed infill pellets and required continuous raking and clean‑up, and that a prior synthetic field at that site lasted only six years. Other commenters questioned the study’s cost assumptions for natural‑grass maintenance and urged the city to commission targeted site visits to high‑use grass fields that have adopted different construction and management techniques before deciding on a preferred surface.

Staff response and next steps: The commission did not take action on the turf question at the Aug. 26 meeting. Staff announced they will schedule a special meeting to present the full consultant study and receive additional public input; commissioners asked staff to add analysis of organically managed fields, to examine recycling and PFAS‑free synthetic options, and to provide clearer, documented cost comparisons tied to local climate and soil conditions.

Why it matters: The choice of field surface affects playable hours, maintenance costs, stormwater and lifecycle environmental impacts, and potential exposure to microplastics and persistent chemicals. Commissioners asked staff for more complete comparisons, including real‑world examples and lifecycle analysis, before recommending capital or policy changes.

Public comment highlights:

- Pro‑synthetic: Manny Diaz (TenCate Grass consultant) — modern synthetic turf options can be PFAS‑free and recyclable; artificial surfaces provide year‑round playability and lower long‑term operating costs for high‑use sites. - Pro‑grass/organic management: Multiple commenters and community groups cited field case studies and urged the city to investigate organically managed natural grass systems that report higher than expected carrying capacity. - Operational concerns: Residents reported pellet infill shedding, short lifespans of some synthetic fields and high maintenance burdens.

The commission invited more technical submissions and asked staff to return with a fuller, evidence‑based presentation at a special public meeting.
