Protected Tree Removal Permit Fee Estimator
Estimate the permit fee required to legally remove a protected tree, including base application fees, diameter-based surcharges, species multipliers, and tree replacement mitigation costs.
Measured at 4.5 ft above ground. Minimum protected threshold is typically 6–12 inches DBH.
Formula
Per-Tree Permit Fee = (Base Fee + DBH Surcharge) × Species Multiplier × Location Multiplier × Condition Factor
- Base Fee: $150 flat application fee per permit
- DBH Surcharge: $10/inch for first 24 inches + $20/inch for each inch above 24 inches
- Species Multiplier: 0.75× (invasive) | 1.0× (common) | 1.5× (heritage) | 2.0× (rare/endangered)
- Location Multiplier: 1.0× (private interior) | 1.25× (private street-facing) | 1.5× (right-of-way) | 1.75× (protected zone)
- Condition Factor: 1.0 (good) | 0.85 (fair) | 0.65 (poor) | 0.40 (dead/hazardous)
- Multi-Tree Discount: 5% per additional tree, maximum 30%
- Arborist Report: $350 base + $25 per additional tree
- Replacement Mitigation: (Num Trees × Ratio × Cost per Tree) × 1.20 installation factor
- Expedited Processing: 50% surcharge on total permit fee
- Administrative Fee: 5% of permit fee, minimum $25
- Grand Total = Permit Fee + Arborist Fee + Replacement Cost + Expedite Fee + Admin Fee
Assumptions & References
- Protected tree thresholds vary by jurisdiction; commonly 6–12 inches DBH triggers permit requirements.
- Base fees and surcharge rates are modeled on typical municipal ordinances (e.g., City of Los Angeles, Austin, Portland tree ordinances).
- Heritage/significant tree designations follow ISA (International Society of Arboriculture) and local registry criteria.
- Replacement ratios follow common mitigation standards: 1:1 for dead trees, 2:1 for poor condition, 3:1 for healthy trees.
- Arborist report requirements typically apply to trees with DBH ≥ 12 inches or heritage-designated trees.
- Replacement tree costs are based on standard nursery pricing for container-grown trees; installation adds ~20%.
- Expedited processing (5–10 business days vs. standard 30–60 days) is offered by many jurisdictions at a surcharge.
- Fees do not include utility notification, traffic control, stump grinding, or disposal costs.
- Some jurisdictions cap total permit fees; verify with your local urban forestry or planning department.
- Federal or state permits may be required separately for trees in wetlands, floodplains, or habitat for listed species (ESA Section 7/10).
- Estimates carry ±20% variance due to local fee schedules, inspector discretion, and project-specific conditions.
