Petaluma's Tree Protection: The Rules That Matter
Every city handles tree protection a little differently. In Petaluma, California, there are 3 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.
Heritage & Protected Trees
Petaluma's Heritage and Landmark Tree ordinance bars removal, substantial alteration, or soil disturbance in the drip line of any city-registered heritage or landmark tree without a permit from the community development director. Trees reach the city's official register only through owner nomination and Historic and Cultural Preservation Committee review under Petaluma Municipal Code Chapter 8.28.
Key details: Governing chapter: Petaluma Municipal Code Chapter 8.28. Permit required for: Removal, alteration, or drip-line soil disturbance. Permit issuing authority: Director of community development. Penalty: Infraction plus court-ordered tree replacement. Nomination: Owner-only, filed with community development.
Violating Chapter 8.28 is an infraction under Petaluma Municipal Code Section 8.28.110. Beyond any court-imposed fine, the director of community development can require the violator to replace an illegally removed or altered heritage or landmark tree with trees of reasonably similar or appropriate size, characteristics and variety. The director also strikes a tree from the official register once a lawful removal permit is granted.
This is not one of those rules that cities tend to ignore. Petaluma actively enforces its heritage & protected trees requirements.
Protected Tree Species
Petaluma protects native oaks at four inches DBH, California Buckeye at six inches, California Bay at twelve inches, and Coast Redwood at eighteen inches, plus heritage trees, significant groves, riparian corridor trees, and public right-of-way trees, under Implementing Zoning Ordinance Chapter 17. Removing or damaging any of these without a permit is a misdemeanor enforced by the Community Development Department.
Key details: Native oak threshold: 4 inches DBH (8 oak species listed). California Buckeye threshold: 6 inches DBH. California Bay threshold: 12 inches DBH. Redwood threshold: 18 inches DBH. Enforcing department: Community Development Department.
Section 17.100 makes cutting, damaging or removing a protected tree without a permit a misdemeanor and a public nuisance, enforceable by the City through civil, criminal or administrative action under Title 1 of the Petaluma Municipal Code. A violation during construction can trigger an immediate stop-work order. Where a tree is illegally removed or killed, the penalty is its full appraised replacement value under the Guide for Plant Appraisal; partial damage that the tree survives is billed at that value times the percentage of the tree damaged.
Parkway Planting
Anyone planting a tree in a Petaluma public street or right-of-way must use the city's approved street tree list and planting standards under Petaluma Municipal Code Section 13.08.020. The tree advisory committee recommends that list, and the city council adopts and can amend it by resolution.
Key details: Governing section: PMC § 13.08.020. Approval source: City-approved street tree list. Adopted by: City council resolution. Enforcement: Director of public works. Violation class: Infraction under § 13.08.090.
Planting a street tree that isn't on the city-approved list, or otherwise violating the planting standards, is punishable as an infraction under Section 13.08.090, along with a requirement to replace any illegally removed, damaged or mutilated tree with a healthy one that conforms to the approved list. The city can also pursue abatement of a nonconforming or hazardous planting as a public nuisance.
The Bottom Line
Petaluma's tree protection rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Petaluma is broadly strict or permissive.
