Policy Solution

Street trees



Trees provide cooling through evapotranspiration and shading that decreases temperatures along walkways. Increasing vegetation provides numerous co-benefits like reducing pollution, improving the public realm, and decreasing energy costs. The cost of planting and ongoing maintenance of trees can be a barrier. Providing incentives can encourage private property owners and businesses to plant trees.


Encourage tree planting and protection through incentives such as stormwater fee reductions, tax credits, tax increment financing for property values, or grant programs.

Considerations for Use

Plantings require ongoing maintenance with associated costs and staffing.
