8.36.020 Definitions.

As used in this chapter:

“Associated with a proposal for development” means any land area for which an application for a specific plan, variance, parcel map, subdivision, development/design review or a time extension thereof, site approval (conditional use permit) or building permit has been filed with and is pending consideration by the city or has been approved but the related project and applicable phase thereof has not been completed.

“Drip line” means a line which may be drawn on the ground around a tree directly under its outermost branch tips and which identifies that location where rainwater tends to drip from the tree.

“Grove” means a planting of fruit or nut trees, or other manmade planting of trees without underbrush.

“Heritage tree” means any live tree, shrub or plant which meets at least one of the following criteria:

A. All woody plants in excess of 15 feet in height and having a single trunk circumference of 24 inches or more, as measured four and one-half feet above ground level; or

B. Multitrunk tree(s) having a total circumference of 30 inches or more, measured four and one-half feet from ground level; or

C. A stand of trees, the nature of which makes each dependent upon the others for survival; or

D. Any other tree as may be deemed historically or culturally significant by the community development director or designee because of size, condition, location, or aesthetic qualities.

“Historic landmark” means, for the purposes of this chapter, any tree designated as an historic landmark by city council action.

“Remove” includes any act which will cause a heritage tree to die, as determined by a tree expert, including, but not limited to, acts which inflict damage upon root systems, bark or other parts of tree by fire, application of toxic substances, operation of equipment or machinery; improper watering; changing natural grade of land by excavation or filling the drip line area around the trunk; or by attachment of signs or artificial material piercing the bark of the tree by means of nails, spikes or other piercing objects.

“Reviewing authority” means the design review committee, planning commission or city council which has the final authority to review projects associated with a proposal for development. (Ord. 103 § 2, 1990)

8.36.030 Exceptions.

The following shall be exempt from the provisions of this chapter:

A. Trees which are fruit or nut bearing shall be exempt except as follows:

1. Where planted in groves, these trees may be removed only pursuant to a tree removal permit issued not earlier than the issuance of grading permits;

2. A tree removal permit shall not be issued for removal of fruit or nut bearing trees in groves until a soil erosion control plan has been submitted to and approved by the city engineer. This plan shall provide for soil and water erosion control during the period between tree removal and construction and for clearing as per the provisions of HMC 8.36.090. Suitable bonds as determined by the city engineer to ensure compliance with the soil erosion control plan shall be posted with the city prior to the issuance of a tree removal permit for fruit or nut bearing trees planted in groves;

Applicants shall be encouraged to retain as many of these trees as feasible and/or incorporate them into the design of any associated development proposal.

B. Trees planted, grown, and/or held for sale by licensed nurseries and/or tree farms or the removal or transplanting of such trees pursuant to the operation of a licensed nursery and/or tree farms.

C. Trees within existing or proposed public rights-of-way where their removal or relocation is necessary to obtain adequate line-of-sight distances as required by the city engineer, or his designee.

D. Trees which, in the opinion of the city engineer, or designee, will cause damage to existing public improvements.

E. Trees which require maintenance or removal action for the protection of existing electrical power or communication lines or other property of a public utility as determined by the city engineer or designee.

F. Removal of trees as part of a fire hazard reduction program approved by the fire department.

8.36.110 Protection of existing trees.

Care shall be exercised by all individuals, developers and contractors working near trees to be preserved so that no damage occurs to the trees. All construction shall protect the health of trees to remain, relocated trees, and new trees planted to replace those removed in accordance with the following measures:

A. All trees to be saved shall be enclosed by an appropriate construction barrier, such as chain link fence or other means acceptable to the community development director or designee, prior to the issuance of any grading or building permit and prior to commencement of work. The protective devices are to remain in place during all phases of construction and may not be removed without the written consent of the community development director or designee until construction is complete;

B. No substantial disruption or removal of the structural or absorptive roots of any tree shall be performed;

C. During construction when major tree root(s) are exposed and the root(s) are to be severed, a clean hand saw shall be used to make the cut, and the cut surface shall be treated with a clear polyurethane;

D. No fill material shall be placed within three feet from the outer trunk circumference of any tree;

E. No fill materials shall be placed within the drip line of any tree in excess of 18 inches in depth. This is a guideline and is subject to modification to meet the needs of individual tree species as determined by a qualified tree expert;

G. No construction by-products shall be deposited within the dripline;

H. No construction, including structures and walls, that disrupts the root system shall be permitted. As a guideline, no cutting of roots should occur within a distance equal to three and one-half times the trunk diameter, as measured at ground level. Actual setbacks may vary to meet the needs of individual tree species as determined by a tree expert. Where some root removal is necessary, as determined by a tree expert, the tree crown may require thinning to prevent wind damage;

I. Windrows to be preserved shall have adequate provisions for deep watering and limit surface watering within 15 feet of trunk;

J. The community development director or his designee may impose such additional measures determined necessary to preserve and protect the health of trees to remain, relocated trees, and new trees planted to replace those removed;

K. Trees shall be removed no earlier than 45 calendar days prior to issuance of building permits. However, applicants shall be encouraged to retain as many trees as feasible and/or incorporate them into the design of development project. (Ord. 103 § 12, 1990)

8.36.120 Tree maintenance.

A. The maintenance of trees standing upon public parkway or private homeowner-owned property shall be the responsibility of the owner or owners of those properties except that trees that are in the public right-of-way and that are determined by the city engineer to be a public safety hazard shall be abated by the city.

B. Builders shall be required to prune, treat, and maintain existing trees and plant new ones in such a fashion that when the trees become property of the city, association, or private owner of the trees will be free of various damage, pests, diseases, and dead branches. The trees shall be in good biological and aesthetic condition upon acceptance. (Ord. 103 § 13, 1990)

8.36.130 Separate offenses.

Each tree removed in violation of this chapter shall constitute a separate offense. (Ord. 370 § 25, 2012; Ord. 103 § 14, 1990)
