ORDINANCE NO. 2883
AN ORDINANCE ADDING A NEW CHAPTER TO THE ASHLAND MUNICIPAL CODE - LAND USE ORDINANCE REGARDING TREE PRESERVATION AND PROTECTION
THE PEOPLE OF THE CITY OF ASHLAND DO ORDAIN AS FOLLOWS:
SECTION 1. Chapter 18.61 of the Ashland Municipal Code - Land Use Ordinance is added to read:
TREE PRESERVATION AND PROTECTION
The City of Ashland recognizes the importance of trees to the character and beauty of Ashland as well as the role that trees have in advancing the public health, safety and welfare. The City has therefore determined that reasonable regulation of the removal of certain trees is necessary and that this regulation of trees is based upon the following general guidelines:
A. The City recognizes that trees can provide soil stability, noise buffering, and wind protection benefits. The City of Ashland greatly values trees for their ecological importance, temperature mitigation, enhanced wildlife habitat and aesthetics.
B. The City recognizes the special significance of heritage and distinctive trees, and values the contribution, which such trees make to the beauty and quality of life of Ashland.
C. The City recognizes that because of the known benefits of trees, development property should be protected from unregulated removal of trees prior to the approval of development plans. Trees on such properties should be preserved so that they may be considered for incorporation into development plans.
D. The City recognizes that residents in single family zones should have the freedom to determine the nature of their private landscaped surroundings.
E. The City recognizes that city-owned property and properties located in multi-family residential zones often have special landscaping circumstances, and that these special circumstances have the potential to affect significantly larger numbers of persons if unregulated. Because of this, such properties require reasonable regulation.
A. Arborist means a person who has met the criteria for certification from the International Society of Arboriculture or American Society of Consulting Arborists, and maintains his or her accreditation.
B. Caliper Inch refers to a manner of expressing the diameter inches of a tree as calculated by measuring the tree's circumference and dividing by Pi (approximately 3.14159). Specially calibrated "diameter tapes" or "calipers" are used to determine caliper inches.
C. Dead Tree means a tree is lifeless. Such evidence of lifelessness may include unseasonable lack of foliage, brittle dry branches, or lack of any growth during the growing season.
D. Diameter at breast height or DBH means the diameter of the trunk, at its maximum cross section, measured 54 inches (4 1/2 feet) above mean ground level at the base of the trunk.
E. Dripline means an imaginary vertical line extending downward from the outermost tips of a tree's branches to the ground.
F. Heritage Tree means any tree listed on the official City of Ashland Heritage Tree list adopted by the City Council.
G. Immediate danger of collapse means that the tree may already be leaning, with the surrounding soil heaving, and/or there is a significant likelihood that the tree will topple or otherwise fail and cause damage before a tree removal permit could be obtained through the non-emergency process. "Immediate danger of collapse" does not include hazardous conditions that can be alleviated by pruning or treatment.
H. Person means any individual or legal entity.
I. Removal means to cut down a tree, or remove 50% or more of the crown, trunk, or root system of a tree; or to damage a tree so as to cause the tree to decline and/or die. "Removal" includes topping. "Removal" includes but is not limited to damage inflicted upon a root system by application of toxic substances, operation of equipment and vehicles, storage of materials, change of natural grade due to unapproved excavation or filling, or unapproved alteration of natural physical conditions. "Removal" does not include normal trimming or pruning of trees.
J. Significant Tree means a "tree" having a trunk 18 caliper inches or larger in diameter at breast height (DBH).
K. Staff Advisor means the Planning Director or the Planning Director's designee.
L. Topping means the severe cutting back of a tree's limbs to stubs 3 inches or larger in diameter within the tree's crown to such a degree so as to remove the natural canopy and disfigure the tree. Topping does not include the practice of "pollarding" when conducted in accordance with the standards established by the International Society of Arboriculture.
M. Tree means any woody plant having a trunk six caliper inches or larger in diameter at breast height (DBH). If a tree splits into multiple trunks above ground, but below 4.5 feet, the trunk is measured at its most narrow point beneath the split, and is considered one tree if greater than six inches DBH. Plants commonly planted as shrubs, including but not limited to English laurel, photinia, arborvitae, poison oak, English holly, and English ivy shall not be considered a "tree". Trees specifically planted and maintained as a hedge shall also not be considered a "tree".
N. Tree Account means an account established by resolution of the Council for the receipt of funds to be utilized for future tree purposes, as outlined in the resolution.
O. Tree Removal Permit means written authorization from the City for a tree removal to proceed as described in an application, such authorization having been given in accordance with this chapter.
P. Tree Protection Zone means the area reserved around a tree or group of trees in which no grading, access, stockpiling or other construction activity shall occur as determined by the Staff Advisor based on review of the tree and site conditions.
18.61.025 Heritage Trees
A. The City of Ashland recognizes that specific trees in Ashland are deserving of special status due to distinctive form, size, age, location, species, unique qualities, or historical significance.
B. Any person may nominate, with the written consent of the property owner, a mature tree for consideration as a Heritage Tree. This nomination shall include all information necessary for evaluation based on the items described in section A above. The Tree Commission shall review all nominations and shall make a written final recommendation to the City Council. The City Council shall review the recommendation and make the final determination for Heritage Tree status.
C. Should the Council approve the nomination, the tree shall be included on the Heritage Tree list adopted by resolution of the City Council. The property owner shall be notified of the Council's action.

18.61.042 Approval and Permit Required.
A person who desires to remove a tree, not otherwise exempted in 18.61.035, shall first apply for and receive one of the following tree removal permits before tree removal occurs:
A. TREE REMOVAL - EMERGENCY PERMIT:
- 1. If the condition of a tree presents an immediate danger of collapse, as defined in 18.61.020, and represents a clear and present hazard to persons or property, an emergency tree removal permit may be issued and the payment of a fee may be waived.
- 2. Emergency tree removal permits are approved by the Staff Advisor. The Staff Advisor may require the applicant to hire an arborist to review the evidence to ascertain whether the tree presented an immediate danger of collapse.
B. TREE REMOVAL - VERIFICATION PERMIT:
- 1. If a site has received development approval through a planning action consistent with the standards of this chapter, then a Verification Permit shall be required for those trees approved for removal through that process. To obtain a verification permit, an applicant must clearly identify on the property the trees to be removed by tying pink tagging tape around each tree and submitting a site plan indicating the location of the requested trees. Vegetation 4" to 6" DBH that is to be removed shall also be marked with pink tagging tape. The Staff Advisor may require the building footprint of the development to be staked to allow for accurate verification of the permit application. The Staff Advisor will then verify that the requested trees match the site plan approved with the planning action. The City shall require the applicant to mitigate for the removal of each tree pursuant to AMC 18.61.084. Such mitigation requirements shall be a condition of approval of the original development permit.
- 2. Verification permits shall be required prior to the issuance of a building permit for the subject property.
C. TOPPING PERMIT: Topping is an injurious pruning practice which may lead to stress, disease, and decay in trees. It should be avoided whenever an alternative exists.
- 1. A topping permit may be issued only if the following apply:
- a. A utility, public agency, or other person who routinely tops trees in furtherance of public safety, may apply for a topping permit pursuant to this section based upon an arborist's report establishing a methodology for topping in compliance with this subsection.

If the application is for a Tree Removal-Staff Permit, the applicant shall submit specific written findings and evidence addressing the criteria in section 18.61.080 for issuance of a Tree Removal-Staff Permit.
C. Misrepresentation of any fact necessary for the City's determination for granting a tree removal permit shall invalidate the permit. The City may at any time, including after a removal has occurred, independently verify facts related to a tree removal request and, if found to be false or misleading, may invalidate the permit and process the removal as a violation. Such misrepresentation may relate to matters including, without limitation, tree size, location, health or hazard condition, justification for issuance of permit, or owner's authorized signature.
18.61.080 Criteria for Issuance of Tree Removal - Staff Permit.
An applicant for a Tree Removal-Staff Permit shall demonstrate that the following criteria are satisfied. The Staff Advisor may require an arborist's report to substantiate the criteria for a permit.
A. Hazard Tree: The Staff Advisor shall issue a tree removal permit for a hazard tree if the applicant demonstrates that a tree is a hazard and warrants removal.
- 1. A hazard tree is a tree that is physically damaged to the degree that it is clear that it is likely to fall and injure persons or property. A hazard tree may also include a tree that is located within public rights of way and is causing damage to existing public or private facilities or services and such facilities or services cannot be relocated or the damage alleviated. The applicant must demonstrate that the condition or location of the tree presents a clear public safety hazard or a foreseeable danger of property damage to an existing structure and such hazard or danger cannot reasonably be alleviated by treatment or pruning.
- 2. The City may require the applicant to mitigate for the removal of each hazard tree pursuant to AMC 18.61.084. Such mitigation requirements shall be a condition of approval of the permit.
B. Tree that is Not a Hazard: The City shall issue a tree removal permit for a tree that is not a hazard if the applicant demonstrates all of the following:
- 1. The tree is proposed for removal in order to permit the application to be consistent with other applicable Ashland Land Use Ordinance requirements and standards. (e.g. other applicable Site Design and Use Standards). The Staff Advisor may require the building footprint of the development to be staked to allow for accurate verification of the permit application; and
- 2. Removal of the tree will not have a significant negative impact on erosion, soil stability, flow of surface waters, protection of adjacent trees, or existing windbreaks; and
- 3. Removal of the tree will not have a significant negative impact on the tree densities, sizes, canopies, and species diversity within 200 feet of the subject property. The City shall grant an exception to this criterion when alternatives to the tree removal have been considered and no reasonable alternative exists to allow the property to be used as permitted in the zone. Nothing in this section shall require that the residential density be reduced below the permitted density allowed by the zone. In making this determination, the City may consider alternative site plans or placement of structures or alternate landscaping designs that would lessen the impact on trees, so long as the alternatives continue to comply with other provisions of the Ashland Land Use Ordinance.
- 4. The City shall require the applicant to mitigate for the removal of each tree granted approval pursuant to AMC 18.61.084. Such mitigation requirements shall be a condition of approval of the permit.
18.61.084 Mitigation Required.
An applicant may be required to provide mitigation for any tree approved for removal. The mitigation requirement shall be satisfied by one or more of the following:
A. Replanting on site. The applicant shall plant either a minimum 1 ½-inch caliper healthy and well-branched deciduous tree or a 5-6 foot tall evergreen tree for each tree removed. The replanted tree shall be of a species that will eventually equal or exceed the removed tree in size if appropriate for the new location. The tree shall be planted and maintained according to the specifications in the City Tree Planting and Maintenance Guidelines as approved by the City Council.
B. Replanting off site. If in the City's determination there is insufficient available space on the subject property, the replanting required in subsection A shall occur on other property in the applicant's ownership or control within the City, in an open space tract that is part of the same subdivision, or in a City owned or dedicated open space or park. Such mitigation planting is subject to the approval of the authorized property owners. If planting on City owned or dedicated property, the City may specify the species and size of the tree. Nothing in this section shall be construed as an obligation of the City to allow trees to be planted on City owned or dedicated property.
C. Payment in lieu of planting. If in the City's determination no feasible alternative exists to plant the required mitigation, the applicant shall pay into the tree account an amount as established by resolution of the City Council.
18.61.092 Expiration of Tree Removal Permits.
Tree removal permits shall remain valid for a period of 180 days from the date of issuance or date of final decision by a hearing body, if applicable. A 30 day extension shall be automatically granted by the Staff Advisor if requested in writing before the expiration of the permit. Permits that have lapsed are void. Trees removed after a tree removal permit has expired shall be considered a violation of this Chapter.
18.61.094 Conditions of Approval for Tree Removal Permits.
A. The City may impose conditions of approval on any Tree Removal Permit if the condition is reasonably related to preventing, eliminating or mitigating a negative impact or potential negative impact on natural features or processes or on the built environment of the neighborhood which is as created or contributed to by the approved tree removal.
B. Conditions of approval may include, but are not limited to:
- 1. Requiring modifications in the location, design or intensity of a development or activities on a site or to require or prohibit certain construction methods. Modifications may result in a decrease in size of residential or commercial structures, but modifications shall not reduce the density of residential development below the permitted density allowed by the zone;
- 2. Requiring vegetation not requiring a tree removal permit to remain in place or be planted.
- 3. Requiring the removal of injurious or noxious vegetation (such as English Ivy) from other trees on the property.
