Tree Protection in Fairfield, CA

If you live in Fairfield or are thinking about moving there, tree protection are one of those things you probably won't think about until they affect you directly. Fairfield has 3 specific rules on the books covering different aspects of tree protection, and some of them might surprise you.

Parkway Planting

When a new building or land use is approved in Fairfield, Section 16.5.1(f) requires a deposit to fund planting street trees in the parkway strip fronting the lot: one tree per interior lot under 75 feet of frontage, one more per extra 75 feet, and three trees on every corner lot.

Key details: Governing section: FMC § 16.5.1(f). Interior lot ratio: 1 tree per lot under 75-ft frontage. Corner lot ratio: 3 trees per corner lot. Easement: 8-foot tree-planting easement may apply. Parkway defined at: FMC § 25.36.2(A).

Failure to pay the required street-tree fee or dedicate the planting easement holds up final map recordation, building permit issuance, or a certificate of occupancy under Section 16.5.1's list of trigger points; the City will not sign off on the project until the deposit is made and any required easement is recorded.

Protected Tree Species

On undeveloped private property in Fairfield, four native tree species are automatically protected once they reach 6 inches in trunk diameter: native oaks, bay laurel, madrone and buckeye, listed by name in Section 25.36.3(C) of the Tree Conservation ordinance.

Key details: Governing section: FMC § 25.36.3(C). Protected species: Native oak, bay laurel, madrone, buckeye. Size threshold: Over 6 inches diameter at breast height. Applies to: Undeveloped private property. Measurement point: 4.5 feet above ground level.

Removing a qualifying native oak, bay laurel, madrone or buckeye over 6 inches in diameter from undeveloped private property without a Tree Removal Permit is unlawful under Section 25.36.4, charged as an infraction under FMC § 1.7, and triggers mitigation planting of three replacement inches for every inch of trunk removed under Section 25.36.9.

Compared to other cities, Fairfield takes a harder line on protected tree species. The enforcement and penalty structure reflects that.

Heritage & Protected Trees

Fairfield protects individual trees for their history, rarity or size, not just their species. Section 25.36.3(D) lets the City designate any tree or group of trees as protected during project review or a special study based on habitat, historic or cultural value, aesthetic importance, uniqueness, or unusual size or age.

Key details: Governing section: FMC § 25.36.3(D). Designation basis: Habitat, historic/cultural, aesthetic, rarity, size/age value. Who designates: City during project review or special study. No size floor: Applies regardless of trunk diameter. Same protections as: All protected trees under §§ 25.36.4-25.36.5.

A tree designated protected under Section 25.36.3(D) for its historic, aesthetic or habitat value cannot legally be removed or damaged without a Tree Removal Permit or discretionary project approval; doing so is an infraction under Section 25.36.4, with a mitigation planting requirement of three replacement inches per inch removed under Section 25.36.9.

Compared to other cities, Fairfield takes a harder line on heritage & protected trees. The enforcement and penalty structure reflects that.
