Tree Preservation Enhancement Amendment Act of 2025

The Tree Preservation Enhancement Amendment Act of 2025 updates Washington, D.C.'s tree protection rules by lowering the size threshold for protected trees and adjusting fees. It reduces the minimum trunk size for a "Special Tree" from 44 inches to 25 inches, expanding the number of trees requiring removal permits. The bill increases fees for removing Special Trees (to $55-$100 per inch of trunk size) and introduces new fees for Heritage Trees ($350 per inch or $250 per inch plus a conservation easement). Additionally, it limits the Tree Fund's use for public property plantings to 25% of the fund's average annual receipts.

MODERATE
The bill was finalized and signed into law, changing the official title year from 2025 to 2026. The substantive policy changes remain the same: the definition of a 'Special Tree' was lowered to include trees with a 40-inch trunk diameter (previously 44 inches), and the Mayor is now required to automatically adjust fines and fees for inflation starting in 2029. Additionally, the Tree Fund was modified to allow money to be used for tree planting on private land, while maintaining its use for public projects and subsidies for hazardous tree removal.
Scope change
The bill's scope regarding tree protection was expanded by lowering the size threshold for 'Special Tree' status from 44 inches to 40 inches, thereby including more trees under the protection and fine regulations.
