Fence & Retaining Walls

Planning Department approval is not required for new and reconstructed fences Section 17.4.27 of the Municipal Code. Fences within 5 feet of a street abutting property line are limited to 4 feet in height and must be visually open. Fences more than 5 feet from the front property line may be up to 6 feet in height, must be screened with landscaping and may be constructed of a solid material.

Fences may not be constructed in the public right-of-way without the approval of a revocable encroachment agreement. Because the public right-of-way is almost always wider than the paved roadway width and the pavement is not always centered in the right-of-way, a property line survey may be required. For additional information, please review Section 17.15.3 of the Orinda Municipal Code.

Protected trees cannot be removed without a Tree Removal Permit. Trees are protected if they are:

  1. On Vacant Property - 6 inches or more in diameter, regardless of species.

  3. Riparian trees - 4.5 inches in diameter within 30 feet of the bank of a water course.
  4. Required as condition of development approval, regardless of species.

The City Engineer review ensures the safety of the structure and design review ensures that the site and landscape plan "retains, enhances and restores appropriate riparian vegetation."
