Accessibility and surfacing choices split commissioners as heat concerns arise
Summary
Commissioners pressed designers on surfacing options that balance ADA accessibility, maintenance and summer heat. Staff said full PIP or artificial turf with a light micro sand infill improves accessibility and does not retain as much heat as dark rubber infill; cork is not currently approved by safety standards.
Commissioners and residents pressed staff on surfacing choices for both accessibility and heat. Eric (staff) said the proposed surfacing—either full poured-in-place (PIP) or artificial turf with micro sand infill—was chosen for accessibility and maintenance reasons and that the lighter color should dissipate heat better than dark rubber mulch.
"The surfacing in and of itself is a 100% handicap accessible," Eric said, noting interior walkways and the central structure were prioritized for wheelchair access. Blake added that artificial turf with micro sand infill tends not to retain the same heat as rubber crumb-filled turf athletic fields.
A commissioner asked about cork as an accessible material; Blake said cork has not yet been approved by the relevant safety standard (NPSI) and its durability is unproven. Commissioners urged staff to continue weighing trade-offs between heat mitigation and ADA requirements before the September decision.
