Title 22 — PLANNING AND ZONING[1]Chapter 22.172 — NONCONFORMING USES, BUILDINGS AND STRUCTURES

§ 22.174

Los Angeles County Zoning Code · 2026-06 edition · updated 2026-07-25 · Los Angeles County

22.174.010 - Purpose.

The Oak Tree Permit is established: (a) to recognize oak trees as significant historical, aesthetic, and ecological resources, and as one of the most picturesque trees in Los Angeles County, lending beauty and charm to the natural and manmade landscape, enhancing the value of property, and the character of the communities in which they exist; and (b) to create favorable conditions for the preservation and propagation of this unique, threatened plant heritage, particularly those trees which may be classified as heritage oak trees, for the benefit of current and future residents of the County.

It is the intent of the Oak Tree Permit to maintain and enhance the general health, safety and welfare by assisting in counteracting air pollution and in minimizing soil erosion and other related environmental damage. The Oak Tree Permit is also intended to preserve and enhance property values by conserving and adding to the distinctive and unique aesthetic character of many areas of the County in which oak trees are indigenous. The stated objective of the Oak Tree Permit is to preserve and maintain healthy oak trees in the development process.

22.174.060 - Findings.

A.

Common Procedures. Findings and decision shall be made in compliance with Section 22.222.200 (Findings and Decision) and include the findings in Subsection B, below.

B.

Findings.

1.

The proposed construction or proposed use will be accomplished without endangering the health of the remaining oak trees subject to Title 22 regulations, if any, on the subject property.

2.

The removal or relocation of the oak trees proposed will not result in soil erosion through the diversion or increased flow of surface waters which cannot be satisfactorily mitigated.

3.

In addition to the above facts, at least one of the following findings apply:

a.

That the removal or relocation of the oak trees proposed is necessary as continued existence at present locations frustrates the planned improvement or proposed use of the subject property to such an extent that:

i.

Alternative development plans cannot achieve the same permitted density or that the cost of such alternative would be prohibitive, or

ii.

Placement of such oak trees precludes the reasonable and efficient use of such property for a use otherwise authorized;

b.

That the oak trees proposed for removal or relocation interferes with utility services or streets and highways, either within or outside of the subject property, and no reasonable alternative to such interference exists other than removal of the trees; or

c.

That the condition of the oak trees proposed for removal with reference to seriously debilitating disease or danger of falling is such that it cannot be remedied through reasonable preservation procedures and practices.

4.

The removal of the oak trees proposed will not be contrary to or be in substantial conflict with the intent and purpose of the Oak Tree Permit procedure.

C.

Relocation of Trees. For purposes of interpreting this Section, it shall be specified that while relocation is not prohibited by this Chapter, it is a voluntary alternative offering sufficient potential danger to the health of an oak tree as to require the same findings as removal.

(Ord. 2022-0008 § 108, 2022; Ord. 2019-0004 § 1, 2019.)

22.174.070 - Conditions of Approval.

Conditions may be imposed to ensure that the approval will be in accordance with the findings required by Section 22.174.060 (Findings and Decision). Such conditions may involve, but are not limited to, the following:

A.

The replacement of oak trees proposed for removal or relocation with oak trees of a suitable type, size, number, location, and date of planting. In determining whether replacement should be required, the Commission, Hearing Officer, or Director shall consider but is not limited to the following factors:

The vegetative character of the surrounding area.

2.

The number of oak trees subject to this Chapter which are proposed to be removed in relation to the number of such oak trees currently existing on the subject property.

3.

The anticipated effectiveness of the replacement of oak trees, as determined by the Oak Tree Report submitted by the applicant and evaluated by the Fire Department.

4.

The development plans submitted by the applicant for the proposed construction or the proposed use of the subject property.

5.

The oak trees on the site plan be physically identified by number on a tag affixed to the north side of the tree in a manner preserving the health and viability of the tree. The tag shall be composed of a noncorrosive all-weather material and shall be permanently affixed to the tree. The oak tree shall be similarly designated on the site plan in a manner acceptable to the Director.

6.

Corrective measures for oak trees noted on the Oak Tree Report as requiring remedial action be taken, including pest control, pruning, fertilizing, and similar actions.

7.

To the extent feasible as determined by the Director, utility trenching shall avoid encroaching into the protected zone on its path to and from any structure.

8.

At the start of grading operations and throughout the entire period of development, no person shall perform any work for which an Oak Tree Permit is required unless a copy of the Oak Tree Report, location map, fencing plans, and approved Oak Tree Permit and conditions are in the possession of a responsible person and also available at the site.

C.

The applicant shall provide an oak tree information manual prepared by and available from the Fire Department to the property owner, subsequent property owner, and any homeowners association.
