The Snoqualmie Natural Infrastructure Assessment establishes the stormwater retention, water quality and climate stability values of Snoqualmie’s urban forest. Using geographically referenced land cover and a proven Ecosystem Service Valuation method, this assessment analyzes the natural infrastructure benefits delivered by the City’s urban forest to the community at-large. Recommendations and resources are also provided.
In a nutshell, this resource offers:
- Quantified values (including in dollars) of stormwater, carbon sequestration, and water quality ecosystem services of urban natural areas and street trees.
- A net present value analysis of the value of ecosystem service provision for Snoqualmie's natural areas over 50 years.
- Recommendations for preserving and enhancing natural infrastructure in Snoqualmie.
How to use this resource:
- A starting place for methodologies to calculate the stormwater, carbon sequestration, and water quality values of urban forests.
- An example of how data can illustrate the value of natural infrastructure.
