RETENTION OR REMOVAL OF PARK AND PARKWAY TREES
It shall be the responsibility of the Parks, Beaches and Recreation Commission to
develop and maintain a rather restricted list of trees in the community
Attachment 1) which should be retained to the exclusion of all normal
problems. This list will contain landmark trees, special trees of beauty, stately
trees which contribute to an entire neighborhood, dedicated trees, etc. These
trees will be identified, mapped and recorded. Subsequent to this they will be
given special treatment to retain them, as deemed appropriate by the General
Services Director. If said special treatment is not determined to be adequate to
retain the identified tree, a full report shall be made to the Commission before
any other action is taken.
Whenever it is necessary to prune tree roots in parkways or other public areas in
order to correct or prevent damage being caused by the subject tree, every
reasonable effort shall be made to save the tree. It will still be necessary to meet
the City's standards relative to grades and alignments, with the exception of
those special trees discussed in Paragraph 1 of this policy statement
If it is necessary for a tree other than that included in Paragraph 1 to be given
special treatment, each tree shall be considered individually on its own merits to
determine whether the tree should be retained or replaced. all parkway trees
included in this category must be subjected to and meet the following criteria:
1. Have a tree hazard evaluation performed by the City arborist
Attachment 2).
2. Have sufficient life expectancy to merit special consideration.
3. Have contiguous property owners be desirous of retaining the tree
if special treatment of other than the sidewalk repair is necessary to
retain it
4. Be of a desirable species on the official street tree list by the Parks,
Beaches and Recreation Commission.
5. Not have had a consistent history of damaging public or privately
owned property such as sewers, water mains, sidewalks, curbs,
walls, fences, foundations, etc., as indicated per City records, or by
competant authority as a structural engineer, general contractor, or
qualified City official.
G -1 0
6. Not interfere with acceptable drainage if alternate methods of curb
repair are utilized.
Application of the criteria on parkway trees will be conducted by the General
Services Department in coordination with the Parks, Beaches and Recreation
Commission. In applying the criteria, other departments of the City will be
consulted as necessary. If there is any conflict between the application of the
criteria and established standards of the City which cannot be resolved at staff
and Commission level, final resolution will be determined by the City Council.
The Parks, Beaches and Recreation Commission is required to establish a
standing Street Tree Committee to assist the Commission in developing a
community awareness program and provide input to the total street tree
program. Objectives of this Street Tree Committee will be:
1. To obtain /provide representation for each situation as it arises in a
community and /or neighborhood.
2. To recommend innovative and practical techniques that will enable
trees to be saved when imrovements are performed around them.
is
3. To provide recommendations to the Parks, Beaches and Recreation
Commission when tree removal requests are denied by the City
arborist and appealed to the full Commission.
4. To inform the public and further the philosophy of the value of
trees in a community.
5. To pursue procedures whereby larger replacement trees can be
used when trees are removed.
6. To assure that no community has a mass removal effect as projects
occur.
7. Annually review landmark tree locations for inclusion in Council
Policy G -1.
When a tree is removed from the parkway for the sole benefit of the adjacent
property owner, the property owner will be responsible for the cost of removal.
Removal must still be done in accordance with City approval.
