Commission Reviews Tree‑Preservation Rules; Staff Details DBH Thresholds and Replacement Ratios

Jun 19, 2025

Township planning staff reviewed the code’s tree‑preservation rules—trees ≥8 inches DBH require surveys, trees ≥18 inches are 'heritage' and require 1:1 replacement—while commissioners debated whether to require earlier surveys and stronger master‑plan language to protect canopy.

The full story

Planner Laura Hall reviewed the township’s landscaping and tree regulations, explaining that trees with diameters at breast height (DBH) of 8 inches or greater on a development site must be surveyed and that trees 18 inches and larger are considered heritage trees subject to a 1:1 replacement requirement. She explained how non‑heritage trees (8–17 inches) are counted at 0.25 toward replacement totals and that developers may pay a fee in lieu or provide replacement trees on public land if approved.
