Summary

Hanford's tree ordinance singles out one species by name: Hanford Municipal Code § 12.12.020 makes any native Valley Oak (Quercus lobata) over 10 inches in trunk diameter a protected 'heritage tree,' alongside any tree the city council specifically designates for historical or community value, folding both into the chapter's broader duty-bound definition of 'tree.'

"Heritage tree"means any of the following: (1) any Oak Tree native to Central California, Valley Oak Tree (Quercus lobata), with a diameter greater than 10 inches; or (2) any tree or a group of trees specifically designated by the city council for protection because of its historical significance, special character or community benefit. ... "Tree"shall mean any perennial, woody plant species or cultivar that reaches a height exceeding six feet at maturity, whether planted singly or as a hedge, or having secondary branches supported on a main stem or stems. The term "tree" includes street trees and heritage trees.

Full Breakdown

12, Street Trees and Shrubs (Ord. 020 as either (1) any Oak Tree native to Central California, specifically the Valley Oak (Quercus lobata), with a trunk diameter greater than 10 inches, or (2) any tree or group of trees the city council specifically designates for protection because of historical significance, special character or community benefit. The chapter's general term 'tree' is defined broadly as any perennial, woody plant exceeding six feet at maturity, whether single-stemmed or hedge-grown, and the definition expressly folds in both street trees and heritage trees, meaning the heavier protections aren't limited to the Valley Oak alone once council makes a specific designation.

Related definitions set the enforcement vocabulary: 'critical root zone' is measured from the tree's drip line radius plus one foot; 'damaged' covers bark loss over three inches across or splitting of the main trunk; 'dead' requires a director determination of advanced decline; and 'hazard' covers a tree that is dead, likely to fall, diseased, or obstructing traffic, signs, signals or streetlights. 'Director' is defined as the city's parks and recreation department director or designee, and 'city arborist' must be a member of the International Society of Arborists (or an equivalent organization) designated by that director.

530 makes the chapter's remedies non-exclusive, allowing criminal, civil or administrative enforcement in addition to any other remedy available under the municipal code or general law.

Violations & Fines

Section 12.12.520(A) lets the director issue administrative citations of up to $1,000 per participant per tree for violations, on top of the reforestation duties in § 12.12.280, with a specific penalty schedule set by city council resolution. Subsection (B) lets the city order a violator to stop work and file a mitigation plan, approved by the city arborist and agreed to in writing by the property owner, that replaces each removed or damaged tree at a ratio the director sets; construction can't resume until the mitigation is implemented and secured by bond.

Frequently Asked Questions

What makes a tree a protected 'heritage tree' in Hanford?
Under Hanford Municipal Code § 12.12.020, a heritage tree is any native Central California Valley Oak (Quercus lobata) with a trunk diameter greater than 10 inches, or any tree or group of trees the city council specifically designates for its historical significance, special character or community benefit.
Does the ordinance protect every tree in Hanford or just heritage trees?
The chapter defines 'tree' broadly as any woody perennial exceeding six feet at maturity and folds both street trees and heritage trees into that definition, but the strongest protections and penalties attach specifically to designated heritage and street trees, not ordinary yard trees generally.
Who decides if a protected tree is dead or hazardous in Hanford?
The parks and recreation department director, or a designee, makes that call. Section 12.12.020 defines 'dead' as advanced decline determined by the director and 'hazard' as any tree that is dead, likely to fall, diseased, or that obstructs traffic, signs or signals.
What's the penalty for illegally damaging a protected heritage tree in Hanford?
Under § 12.12.520(A) the director can issue an administrative citation of up to $1,000 per participant per tree, and § 12.12.520(B) lets the city order a stop-work and a mitigation plan, approved by the city arborist, that replaces the tree at a ratio the director sets.
