King County addresses urban heat islands through tree canopy goals, cool surfaces, and equity-focused investments under the Strategic Climate Action Plan and the 30-year Land Conservation Initiative.
The SCAP and the 2020 King County Comprehensive Plan call for expanding tree canopy in heat-vulnerable communities, including South King County and unincorporated urban pockets. Strategies include parkway tree planting, cool roofs and pavement, green stormwater infrastructure, and incentives for shade in public right-of-way redesigns. The Land Conservation Initiative protects 65,000 acres of forest and trails over 30 years, which also moderates regional summer temperatures along the I-5 and I-405 corridors.
Heat island policies are aspirational; enforcement happens indirectly through tree code, stormwater code, and capital project review rather than household fines.
