Key Features of a Strong Tree Ordinance
Even though ordinances vary widely in form, content, and complexity, an effective tree ordinance should meet the following criteria:
Clear Goals
- The ordinance should clearly state its purpose.
- Each rule should connect back to these goals so progress can be tracked.
Clear Responsibility and Authority
- One person (like a tree manager or arborist) should oversee all tree-related decisions.
- If multiple people or groups are involved, their duties must be clearly defined.
- The person in charge must also have the authority to enforce the rules.
Built-In Flexibility
- Ordinances should allow for some flexibility depending on the situation.
- Clear performance standards can guide decisions while still allowing room to adapt.
- A fair appeals process should be available, but it shouldn’t be used to weaken good tree management.
Enforcement Rules
- Many ordinances fail because no one is officially in charge of enforcement.
- Effective enforcement can include:
- Fines
- Requiring replacement trees
- Taking away bonds or permits
- These penalties only work if they’re consistently applied.
Performance Standards
- The ordinance should explain what is allowed and what is not.
- It should include clear goals like:
- Minimum tree canopy cover
- Shade levels
- Rules for tree removal
- Standards should apply to the whole urban forest, not just individual trees.
