San Antonio's Climate Action and Adaptation Plan and Tree Canopy Strategy target heat-island reduction through expanded canopy, cool-roof requirements, shaded transit stops, and the citywide goal of growing canopy cover above 30 percent in vulnerable neighborhoods.
San Antonio experiences severe summer urban heat island effects, with South and West Side neighborhoods often 5 to 10 degrees hotter than wealthier North Side areas. The CAAP and SA Tree Canopy Strategy together target equitable canopy expansion through partnerships with the San Antonio River Authority, Bexar County, and nonprofits like Texas Trees Foundation. UDC Section 35-523 requires tree preservation and replacement on private development. Cool-roof rules in the Energy Code, parking lot shade requirements in the UDC, and VIA bus-stop shading complement canopy growth. The Office of Sustainability administers cooling-center activations during extreme heat events and coordinates with Metro Health on heat-illness response.
Removing protected trees without UDC 35-523 permit triggers fines up to 2,000 dollars per day and replacement requirements. Failing to install required parking-lot shade trees under UDC 35-512 blocks certificate of occupancy.
