CITY OF BELLEVUE, WA

The City of Bellevue, WA has lost 9% of its tree canopy over the last 10 years. In response, the city employed Sanborn data and American Forests’ software to quantify the ecological and dollar return on investment in new plantings.

Analysis

The analysis quantified loss over time, measured existing tree canopy as a baseline, quantified ecosystem benefits, and recommended goals per land use. Modeling with CITYgreen software showed that a 5% increase in ROW tree canopy provides an additional 1.9 million cu. ft in stormwater runoff mitigation, valued at $3.7 million.

Implementation

Bellevue will incorporate canopy goals into their green infrastructure master plan to mesh policy with existing city codes. This provides basis of the city’s action plan and priority expenditures to increase its canopy cover.
