Prior to issuance of a grading or building permit, all oak or significant trees on a building site shall be inventoried by the owner of such site or by the contractor as to size and location on the site. Such inventory shall be submitted to the Director, and field checked by City staff to verify the number, size and location.

Damage to any tree during construction shall be immediately reported to the Director by any person causing such damage, the responsible contractor, or the owner of the site, and such persons shall be required to treat the tree for such damage as specified by the Director.

Oil, gasoline, chemicals and other construction materials or equipment which might be harmful to oak and significant sized trees shall not be stored under the dripline or upslope of the tree(s).

Drains shall be installed according to City specifications so as to avoid harm to the oak or significant trees due to excess watering.

Wires, signs and other similar items shall not be attached to oak or significant trees.

Cutting and filling around the base of oak or significant trees shall be done only after consultation with the Director, and then only to the extent authorized. The Director may require professional consultation, at the applicant's cost, to make appropriate determinations.

No paint thinner, paint, plaster or other liquid or solid excess or waste construction materials or waste water shall be dumped on the ground or into any grate between the dripline and the base of oak or significant trees, or uphill from any oak or significant tree where such substance might reach the roots through a leaching process.

Tree protection fences (minimum three (3) foot high visibility fence with metal posts at minimum every ten (10) feet) shall be installed at the dripline to prevent compaction and injury to a tree's surface roots, to prevent injury to oak or significant trees exposing them to disease causing organisms.

Wherever cuts are made in the ground near the roots of oak or significant trees, appropriate measures shall be taken to prevent exposed soil from drying out and causing damage thereto. All cuts within the dripline of a tree are to be made by hand (no backhoes or graders.)

Trimming cuts one (1) inch in diameter and over must be covered at the time the cuts are made with a tree seal pruning compound approved by the Director. All root pruning is to be done by hand.
