13.52.010 INTENT -- PURPOSE. This chapter is adopted because the city has been forested with a variety of healthy and valuable trees which must be protected and preserved, the preservation and reforestation of which is necessary for the health and welfare of the citizens of this city in order to preserve the scenic beauty; maintain property values; prevent erosion of topsoil; protect against flood hazards and the risk of landslides; counteract the pollutants in the air; maintain the climatic balance and decrease wind velocities; and relieve the public costs of installing and maintaining storm water drainage systems. To this end it is reasonable to expect property owners to maintain their trees in a satisfactory condition to keep the City of San Mateo as a sylvan place to live.
It is the intent of this chapter to establish regulations for the protection, removal and preservation of heritage trees within the city in order to retain as many trees as possible consistent with the purpose hereof and the reasonable economic enjoyment of private property. (Ord. 2007-1 § 3; 2007; Ord. 2005-3, § 1, 2005; Ord. 2004-6, § 1, 2004; Ord. 1997-24 § 1, 1997; Ord. 1984-7 § 1, 1984; Ord. 1968-35 § 3 (part), 1968: prior code § 65.50).

(c) It is unlawful for any person or entity to cause damage to a heritage tree compromising its health or structural integrity according to accepted industry standards or to cause damage that is severely detrimental to its overall aesthetics or to remove fencing or other protective barrier surrounding a heritage tree that was required as a condition of development on the property or to violate the terms of any Tree Protection Plan.
(d) Any violation of the terms of this Chapter or any permit issued under this Chapter is unlawful. Knowingly or negligently providing false or misleading information in response to any disclosure requirements of this Chapter or in application for any permit issued under this Chapter, shall constitute a violation of this Chapter and is unlawful. (Ord. 2007-1 § 3; 2007; Ord. 2005-3, § 1, 2005; Ord. 2004-6, § 1, 2004; Ord. 1984-7 § 3, 1984; Ord. 1968-35 § 3 (part), 1968: prior code § 65.52).

13.52.040 REMOVAL -- PERMIT. Any person or entity desiring to remove or prune one or more heritage trees shall apply to the Director for a permit. The application for a permit shall be made on forms provided for this purpose and shall state, among other things, the number and location of the trees to be removed or pruned by types and the reason for removal or pruning of each. The request for such a permit may only be made by the owner or owners of the property on which the trees are located or for pruning by an adjacent property owner of heritage tree limbs extending onto that adjacent property, after notice of the application to the property owner where the heritage tree is located. Heritage tree permits are valid for six months from date of issue. Extensions may be authorized by the Director. The applicant may submit an arborist's report with the permit application to show cause for removal or pruning. Pruning permit applications shall include pruning specifications prepared by a certified arborist.
The Director shall review each application and shall consider and determine the following in rendering a decision:
(a) The condition of the tree or trees with respect to disease, danger of falling, proximity to existing or proposed structures and interference with utility services;
(b) The necessity to remove the tree or trees in order to construct any proposed improvements to allow reasonable economic enjoyment of the property.
(c) The topography of the land and the effect of the removal of the tree on erosion, soil retention and diversion or increased flow of surface waters.
(d) The number of trees existing in the neighborhood on improved property and the effect the removal would have on the established standard of the area and property value.
(e) The number of trees the particular parcel can adequately support according to good arboricultural practices.
In reviewing applications, the Director shall give priority to those based on hazard or danger of disease. (S)he may refer any application to another department, committee, board or commission of the city for a report and recommendation or may require the applicant to supply a certified arborist’s report. (Ord. 2007-1 § 3; 2007; Ord. 2005-3, § 1, 2005; Ord. 2004-6, § 1, 2004; Ord. 1998-8, § 3, 1998; Ord. 1997-24 § 6, 1997; Ord. 1984-7 § 4, 1984; Ord. 1968-35 § 3 (part), 1968: prior code § 65.53).

13.52.050 REFORESTATION. Permits for heritage tree removal, removals without permits and causing damage to heritage trees shall require replanting conditions in accordance with the following guidelines:
(a) Trees removed under jurisdiction of a planning approval pursuant to Chapter 27.71 shall conform with the replacement conditions specified in the planning approval.
(b) Trees removed with a valid tree removal permit shall be replaced in accordance with the direction of the Director. Replacement direction shall include direction on the location and species of the replacement tree. Tree replacement shall be one 24" box size tree approved by the Director, for each tree removed.
(c) Trees removed without a valid tree removal permit shall be replaced by a 48” box size tree for each tree removed. Enhanced replant conditions may be imposed if it is determined by the Director that the value of the removed tree was significantly greater than that of a 48” box tree. In such cases, the determination of the level of replacement shall be within the discretion of the Director, but shall not exceed the actual tree loss as determined by the Replacement Value. In addition to the requirements of this subsection, penalties under Section 13.52.055 or other sanctions allowed by law may be imposed for removal of heritage trees without a permit.
(d) Where the Director determines that replanting is not feasible and/or appropriate, e.g., sufficient trees exist on site, the Director (1) may require that a payment of equal value to the cost of the purchase and installation of the replacement tree(s) be made to the City tree planting fund or (2) may place other conditions on the permit which are of equal value to the cost of the purchase and installation of the replacement tree(s).
(e) Any person causing damage to a heritage tree shall be required to take such steps as may be required by the Director to assure the future vitality of the tree, including costs of treatment and/or construction of protective barriers, or if the Director determines that the damage is so great that the tree is no longer reasonably sustainable, replacement of the damaged tree per subsection (c), above. (Ord. 2007-1 § 3; 2007; Ord. 2005-3, § 1, 2005; Ord. 2004-6, § 1, 2004; Ord. 1998-8, § 3, 1998; Ord. 1997-24 §§ 3 and 6, 1997; Ord. 1989-36 § 1, 1989; Ord. 1984-7 § 5, 1984; Ord. 1968-35 § 3 (part), 1968: prior code § 65.54).

(b) In addition to all other remedies set forth in this code or otherwise provided by law, the following remedies shall be available to the city for violation of this chapter:
(1) Any person or entity violating the provisions of this Chapter may be directed by the Building Official or inspector to stop work and to prepare a mitigation plan to correct the violation and mitigate the damage inflicted. Once the violation is corrected and mitigation implemented, the Building Official or inspector shall allow construction to resume. The mitigation plan shall be filed and approved by the City Arborist, agreed to in writing by the property owner(s) and either implemented or guaranteed by the posting of adequate bond or other security. The mitigation plan shall include measures for protection of any remaining heritage trees on the property and shall provide for replacement of each tree removed or damaged on the property or at locations approved by the Director. The replacement ratio shall be determined by the Director according to the provisions of this Chapter.
(2) If a violation occurs in the absence of development, or while an application for a building permit or discretionary development approval for the lot upon which the tree is located is pending, the Building Official may condition the issuance of any building permit or approval upon the completion of a study, to be conducted by the City or consultant designated by the City, but in either case at the expense of the property owner, for the purpose of providing the City an opportunity to consider and determine appropriate mitigation measures for the tree removal and to insure measures are incorporated into any future development approvals for the property for the protection of any remaining heritage trees in the area.
(3) Administrative Citations may be issued under Chapter 1.10 of the Municipal Code. (Ord. 2007-1 § 3; 2007; Ord. 2005-3, § 1, 2005; Ord. 2004-6, § 1, 2004).
