This article shall be known as the Livermore tree preservation ordinance.
(Ord. 1830 § 3, 2007)
The City of Livermore is forested by a variety of trees, planted on both public and private property. These trees comprise an urban forest that provides tangible benefits to the community. A healthy urban forest reduces air and noise pollution, provides energy-saving shade and cooling, furnishes habitat for wildlife, enhances aesthetics and property values, and is an important contributor to community image, pride, and quality of life. The uncontrolled and indiscriminate destruction of trees within the urban forest detrimentally affects these tangible benefits. Therefore the City Council finds that in order to protect the health, safety, general welfare, and quality of life of the citizens of Livermore, the establishment of basic standards for the preservation and protection of a healthy and sustainable urban forest is essential.
(Ord. 1830 § 3, 2007; Ord. 2065 § 1(A), 2018)
This article establishes the policies, regulations, and standards for the protection of trees on any parcel of land within the City of Livermore. These policies, regulations, and standards are necessary to ensure that the City will continue to realize the tangible benefits provided by its urban forest.
It is the policy of the City to require the preservation of protected trees, unless a reasonable and conforming use of a property justifies the removal, relocation, and/or encroachment into the protected zone of such tree.
The provisions of this article are enacted to:
A. 
Assist in the continuous development and maintenance of a healthy urban forest and sustainable tree cover on lands within the City of Livermore;
B. 
Assist in the continuous development and maintenance of a stable urban forest diverse with trees of various species and age classes;
C. 
Preserve and enhance the aesthetic and quality of life values provided by Livermore's urban forest;
D. 
Preserve and enhance the environmental benefits provided by Livermore's urban forest, including the reduction of air and noise pollution, the conservation of energy resources through shade and cooling, and the provision of wildlife habitat.

A request to remove, relocate or encroach into the protected zone of any number of protected trees on developed single-family, multifamily, commercial, industrial, institutional, mixed-use, open space, riparian or habitat property where such removal, relocation or encroachment is not associated with a development application (i.e., site plan approval, tentative map, etc.);
ii. 
A request to remove or relocate four or more protected trees on developed commercial, industrial, institutional or mixed-use property represents a potentially significant change to the property's previously approved development permit. The Public Works Director shall refer such applications to the community development department for review and determination.
b. 
The Director may approve, conditionally approve, or deny a tree permit application for the removal, relocation or encroachment into the protected zone of a protected tree consistent with the findings established under subsection C of this section. The Director may refer the application to the Beautification Committee, which may approve, conditionally approve, or deny any tree permit application referred by the Director, consistent with the findings established under subsection C of this section.
2. 
Community Development Department Review.
a. 
The following types of tree permit applications shall be submitted to the community development department:
i. 
A request to remove or relocate four or more protected trees on a developed commercial, industrial, institutional or mixed-use property. If warranted (i.e., a significant change to a previously approved development permit), the Director may refer the application to the Planning Commission for determination. Tree permit applications referred to the Planning Commission shall be converted to a site plan approval amendment application and shall be subject to the fees and review process associated therewith.
ii. 
A request to remove, relocate or encroach into the protected zone of any number of protected trees when such application is associated with a development application.
b. 
The Director may approve, conditionally approve or deny the application consistent with the findings established under subsection C of this section. The Director may refer the application to the Planning Commission, which may approve, conditionally approve, or deny the application referred by the Director, consistent with the findings established under subsection C of this section.
c. 
Applications associated with a development application shall be processed concurrently with the development application, and shall be reviewed and approved by the approval body (the Director, design review committee, Planning Commission or City Council) making the final determination on the development application, consistent with the findings established under subsection C of this section.
C. 
Findings. A tree permit may be approved only if such approval is based upon at least one of the following findings:
1. 
That due to the condition of the tree with respect to its general health, status as a public nuisance, danger of falling, proximity to existing or proposed structures, interference with or impacts to utility services, damage to infrastructure or private property, production of invasive suckers or seedlings (i.e., privet or sumac) leading to excessive maintenance requirements, and/or its status as a host for plant, pest or disease endangering other trees or plants with infection or infestation that cannot be controlled or remedied through reasonable preservation and/or preventative procedures and practices, it must be removed.
2. 
That it is necessary to issue a tree permit to remove, relocate, or encroach into the protected zone of a protected tree to enable the reasonable and conforming use of the subject property, or an adjoining property, which is otherwise prevented by the presence of the tree. Reasonable and conforming use of the property shall be determined in accordance with the Livermore general plan and the Livermore Development Code. The applicant must demonstrate to the satisfaction of the Director or the deciding body that there are no reasonable alternatives to the proposed use or design of the property that would cause the request to be unwarranted.
3. 
In addition to the above findings, the following findings may justify removal of a non-native tree (any tree not identified as a California native in LMC § 12.20.160(B)) from the rear yard of a developed single-family residential property:
a. 
The tree is not identified as an ancestral tree; and
b. 
The tree is not of unique importance to the public based on its size, appearance, location, or historical and/or cultural significance; and
c. 
That one or more of the following conditions exist: that the tree based on its size, age or condition is nearing the end of its useful life; is blocking access to sunlight; is dropping an amount of litter or debris resulting in damage or risk to the property; is overhanging a residential structure and cannot be trimmed to alleviate this condition; is damaging other landscaping; has grown out of scale with the portion of the yard it occupies; or that the ongoing maintenance of the tree is an unmanageable burden to the property owner.
(Ord. 1830 § 3, 2007; Ord. 1901 § 3 (Exh. A § 16), 2010; Ord. 2016 § 1(A), 2015; Ord. 2045 § 1(A), 2016; Ord. 2065 § 1(A), 2018)
If the Director or deciding body has reason to believe that construction or development activities may endanger a protected tree, the Director or deciding body may, during development project review or as a condition of development project approval, seek professional consultation at the expense of the person seeking to perform the construction or development of the property in order to determine the measures necessary to safeguard the tree. Such measures may include but are not limited to:
A. 
If encroachment into the protected zone of any protected tree occurs, special construction to allow the roots to breathe and obtain water shall be required.
B. 
The protection zone shall be clearly marked by a three-foot high fence of a highly visible material. Tree wells may be used when advisable. Excavation adjacent to any protected tree shall not be permitted where material damage to the root system will result. The existing ground surface within the protection zone shall not be cut, filled, compacted or paved.
C. 
Oil, gasoline, chemicals and other construction materials or equipment that might be harmful shall not be stored within the protection zone or upslope of the protected tree.
(Ord. 1830 § 3, 2007; Ord. 2065 § 1(A), 2018)
A. 
The Director or deciding body may attach reasonable conditions to the tree permit to ensure compliance with the stated purposes of this chapter.
B. 
The issuance of a tree permit for the removal of a protected tree may be conditioned upon mitigation consisting of the planting of replacement trees on or off site at the sole expense of the applicant, and/or by payment to the urban forestry maintenance fund by the applicant, as determined by the Director or deciding body consistent with the following:
1. 
Single-Family Residential Property.
a. 
The number and type of replacement trees or the amount of funds paid in mitigation may be based on the diminution of economic, aesthetic, environmental and property values, and in relation to the size, age relative to average lifespan, and location of existing trees to be removed, as determined by the Director. In no case shall the replacement value be less than two trees of a minimum 15-gallon size for each tree removed, or one tree of a minimum 15-gallon size, if a California native (as identified under LMC § 12.20.160(B)) species is planted.
b. 
There shall be no mitigation required for protected trees that are determined by the City to be unhealthy or pose a hazard, and where such condition is not the result of an action by the property owner to directly or indirectly damage or remove the tree, or where an invasive species (i.e., privet or sumac) is removed.
2. 
Multifamily Residential (Two or More Units), Commercial, Industrial, Institutional, Mixed-Use, Open Space, Riparian or Habitat Property.
a. 
The number and type of replacement trees or the amount of funds paid in mitigation shall be provided corresponding to the value (see LMC § 12.20.290) of the loss or diminution of economic, aesthetic, environmental, and property values, and in relation to the size, age relative to average lifespan, and location of existing trees to be removed, as determined by the Director. Depending on the size and number of trees to be removed, the City may require the preparation of a report by a certified arborist at the expense of the applicant and in compliance with this chapter to the satisfaction of the Director. In no case shall replacement value be less than three trees of a minimum 15-gallon size, or two trees of a minimum 24-inch box size, or one tree of 48-inch box size for each tree removed.
