ARTICLE e. - REQUIREMENTS
Sec. 5-7-409. - Topping prohibited.

(Code 1976, § V.G-800; Ord. No. 94-8, § 2, 6-14-94)
Sec. 5-7-410. - Tree removal.
A.
Permits for tree removal. A permit shall be required to remove any significant tree on public or private land to which this chapter applies. Permits which do not specifically show or list trees to be removed shall be assumed to not permit tree removal.
B.
Criteria for permits. The City Arborist shall use the following criteria to grant approval for tree removal permits pursuant to this section:
1.
Trees that are dead or in significant and irreversible decline. Significant decline is defined as dead limbs composing more than one-third of the tree crown.
2.
Trees that have a potentially hazardous and incorrectable structure.
3.
Trees that are stunted or malformed due to crowding from adjacent trees or structures.
4.
Trees that have an insect or disease infestation that is not treatable and could cause tree mortality.
5.
Trees that are causing damage to structures as follows:
a.
Sidewalks, curbs, drives, buildings, and other structures. Removal shall be granted if the cost to repair the damage exceeds the appraised value of the tree (using the method established by the International Society
of Arboriculture for tree appraisal), if the process of repair will compromise the health and safety of the tree, or if the tree is determined to be incompatible with the growing space available.
b.
Sewer, gas, electrical, water and other utilities. Removal shall be granted if it can be determined that the tree caused the damage to the utility. If the center of the tree trunk is located within three feet of a utility line, it is assumed to have caused the damage. It will be the applicant's responsibility to demonstrate cause if the tree is beyond three feet from the utility line.
6.
Trees that have yet to cause damage to structures, but are determined to be incompatible with the growing space available as follows:
The applicant shall complete a comprehensive management plan through the City's Community Forests Program or equivalent to address phased removals and appropriate replacement prior to approval of a tree removal permit.
7.
Trees that are significantly inhibiting the utilization of the property and removal can be determined to provide public benefit. The Planning Commission will evaluate permits submitted under this criterion.
8.
Trees on nonresidential property shall only be subject to the replacement criteria in Section 5-7-410C.2.
C.
Replacement.
1.
Trees removed shall be replaced at a one-for-one ratio either on site in a similar location, on site in a different location, or off site as prescribed in the Urban Forestry Guideline Manual based on the determination of the City Arborist.
2.
Trees removed on nonresidential property shall be replaced at a one-for-one ratio in conformance with the most current landscape plan approved by the City based on the determination of the City Arborist. Trees removed on nonresidential property where existing tree density does not comply with that specified in the most current landscape plan shall be replaced at a ratio not to exceed the tree density specified in that plan based on the determination of the City Arborist. In either case trees may be replaced either on site in a similar location, on site in a different location, or off site as prescribed in the Urban Forestry Guideline Manual based on the determination of the City Arborist.
D.
Fee. Each applicant shall pay a fee in an amount as established by resolution of the City Council, which may be amended from time-to-time, to cover the costs of administering this chapter.
