Summary
Hanford property owners must preserve heritage trees in good health, and any construction near a council-designated protected tree needs an arborist-prepared tree protection plan first.
In regard to any heritage tree designated by the city council for protection (hereinafter "protected tree"), any exterior construction work associated with any development project performed within a radius measured from the trunk center equal to 10 times the diameter of the trunk measured at four feet above grade shall require the preparation and submittal of a tree protection plan for review and approval by the director and/or the city arborist prior to the issuance of any permit for a development project. The tree protection plan shall be prepared by a certified arborist.
D. A tree protection plan shall at minimum include the following requirements:
1. Prior to the commencement of any development project, fencing shall be installed at the drip line of any protected tree which will affected by the construction and shall prohibit the storage of any construction materials, equipment or other materials inside the fence. The drip line shall not be altered in any way so as to increase the encroachment of the construction.
2. Prohibit extraction, soil deposit, drainage and leveling within the drip line unless approved by the director and the city arborist.
3. Prohibit disposal or depositing of oil, gasoline, chemicals, paints, solvents or other materials within the drip line or in drainage channels, swales or areas that may lead to the drip line.
4. Prohibit the attachment of wires, signs, ropes, of any foreign objects to any protected tree.

Full Breakdown
Hanford Municipal Code § 12.12.310 requires anyone who owns or controls real property in the city to use reasonable efforts to keep heritage trees healthy. Development applications must disclose each heritage tree's location, species, trunk size, and drip line. For trees the city council designates for protection, any exterior construction within a radius of 10 times the trunk diameter triggers a mandatory tree protection plan, prepared by a certified arborist and approved by the director or city arborist, before any development permit issues.
Violations & Fines
Building without an approved tree protection plan near a designated heritage tree, or damaging one, can trigger stop-work orders, mandatory replacement, and penalties up to $1,000 per tree under § 12.12.520.
