Urban Forestry in Tukwila

Tukwila’s trees are part of what makes our region special. Urban forests benefit our environment, infrastructure, property values, and personal well-being.

Why Trees Matter in Tukwila

Environmental: Trees provide shade, clean air and water, reduce carbon dioxide, and offer wildlife habitat.
Infrastructure: Trees help control stormwater, stabilize slopes, and improve soil.
Property: Trees can increase property values, support business activity, and reduce energy costs.
Health: Trees reduce stress, improve memory, and support physical and mental well-being.

Urban Forestry in Action

The City is conducting tree assessments and improving canopy coverage citywide. Educational programs, classes, and partnerships with organizations like Forterra are helping expand tree care efforts. Restoration work continues along the Green River.

Community members are encouraged to get involved—volunteer, serve on advisory boards, or care for the trees on your own property.

The Urban Forestry program is managed by the City’s Urban Environmentalist.
