Tree protection

Mandate

Case Studies

Summary

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. A tree protection program protects the relocation and replacement of specific trees through the building code. The code can require documentation of existing trees and requiring permitting or fees for removal.

Implementation

Identify protected trees and enforce penalties if existing protected trees are removed.

Considerations for Use

This mandate is most effective in areas with high property turnover rates to protect existing trees.
