San Diego's Climate Action Plan sets a 35 percent urban tree canopy goal by 2035 and pairs reach-code cool-roof and cool-pavement requirements with the Urban Forest Management Plan to lower temperatures in dense and disadvantaged neighborhoods.
The 2022 Climate Action Plan elevates urban forestry and cool surfaces as a Strategy 3 priority. City staff implements through the Urban Forest Management Plan, prioritized planting in Climate Equity Index communities, the Cool Streets pilot reflective coating program, and integration of canopy and reflective material standards into Council Policy 200-14 streetscape standards. Required setbacks for new development reserve parkway space for street trees, and the Land Development Code requires shade trees in surface parking lots above a threshold count of stalls. Heat-island reduction also factors into General Plan land-use, where higher-density transit corridors must provide pedestrian-shade features and reflective treatment as conditions of project approval.
Most heat-island measures are policy and capital programs not enforceable against residents directly, but project conditions of approval are binding and noncompliance can stop final inspection or halt permits at Development Services.
