Tree Removal & Preservation

Tree Preservation Ordinance


Trees play a significant role in the desirability of Santa Rosa as a place to live, work, and play. Toward that end the City Council adopted a Tree Ordinance on October 2, 1990, regulating the removal of large and/or significant trees. Following are common questions and answers regarding this ordinance and tree preservation in Santa Rosa.

Changes in the New Ordinance From Previous Requirements


Heritage trees in R-1 (Single Family Residential) Districts are now regulated; replacement trees are required for those removed by new development; and fines and penalties are included for removing trees without a permit.

Heritage Trees


A heritage tree is a tree or grove of trees designated by the Planning Commission as having a special significance requiring review before removal may be permitted.

The following trees are native to Sonoma County and are considered heritage trees when their diameter or circumference is of a size specified in the ordinance:
  • Bay
  • Big Leaf Maple
  • Black Oak
  • Blue Oak
  • Buckeye
  • Canyon Oak
  • Douglas Fir
  • Interior Live Oak
  • Live Oak
  • Madrone
  • Oregon or White Oak
  • Red Alder
  • Redwood
  • Valley Oak
  • White Alder

Requirements


A permit is required to remove/alter heritage trees in all zoning districts. Non-heritage trees which are four inches or greater in diameter require a permit except in the following zones:
  • R-1
  • R-1-6
  • R-1-7.5
  • R-1-9
  • PRD
  • R-1-PD (unless the specific PD policy requires compliance with the tree ordinance, for example, the Junior College PD) if the property is incapable of being further subdivided. (It may also be exempt if further subdivision is determined unlikely by the Director of Community Development.)

On Undeveloped Property


Permits are required for removal, alteration or relocation of all trees with a 4" or greater diameter in all zoning districts where development is being proposed or may occur in the future.

Protected Tree


 A protected tree is any tree, including a Heritage tree, indicated to be preserved on an approved development plan, an approved tentative map or tentative parcel map, or other approved development.

Exempt Trees


The following trees are exempt from permit requirements in all zoning districts, whether the parcel is developed or not:
  • Acacias
  • Ailanthus
  • Fruit and nut trees (except walnuts)
  • Fruitless mulberry
  • Hawthorn
  • Ligustrums
  • Monterey cypress
  • Monterey pine
  • Poplars
  • Pyracantha
  • Silver maple

Street Trees


Both planting and removal of street trees are addressed in the ordinance. Street tree planting must comply with the City’s street tree list as specified by the City Parks Department. Street tree removal requires a permit from the City Parks Department.

Penalties for Violations of the Tree Ordinance


Both civil fines and / or criminal penalties may apply. Please view the Tree Ordinance for details.

Replacement Requirements


Replacement trees may be required under specific conditions. Please view the Tree Ordinance for details.


Obtain a Permit


 A completed Tree Removal Application (PDF) form must be filed with the Department of Community Development. It will be processed within two weeks for developed properties. Processing for undeveloped properties will occur along the proposed project under review.
