Description of intervention(s) / exposure
BEHAVIORAL - Shade Sail

Experimental: Shade Sail - Shade sails were constructed over passive recreation areas in public parks between pretest and posttest. Shade sails maximized available shade in the passive recreation areas from 11 am to 3 pm in the summer.

No intervention: Unshaded Control - Passive recreation areas in public parks that remained unshaded at pretest and posttest.


BEHAVIORAL: Shade Sail
Shade sails had powder-coated or gout galvanized steel poles and a lighter colored shade cloth to transmit visual light. The shade cloth met Ultraviolet Protection Factor (UPF) ratings to reduce UV under the shade cloth by 94%. The final shade sail designs and sizes were determined with input from parks department staff and complied with all local engineering, building, and planning codes. Shade sails exceeded the minimum safety requirements for strength (for wind and snow load), resistance to light degradation, and UV transmission. The design minimized climbing access points and hazards to adjacent activities.
