To: Burlingame Beautification Commission
DATE: January 5, 2012
FROM: Bob Disco, Park Supervisor
SUBJECT: 1900 Broadway Magnolia Removals
BACKGROUND:
As dictated in the City Street Tree ordinance, it is the duty of the director or its representative
to.... "remove any tree... which in his opinion are objectionable or hazardous in or upon any
street, alley or public place in the City. "
During the planning phase for the remodel of 1900 Broadway, Public Works comments required
the property owner to improve the public frontage. The sidewalk, curb and gutter were
considered to be a necessary improvement and required for approval of the project.
I was called to inspect the trees prior to replacement and recommend the appropriate action
toward the trees that would resolve the raised sidewalk and uneven curb and gutter.
During my inspection I observed that the trees were growing under utility wires and were
previously topped and pruned around the wires.
and signs of decay. The sidewalk was lifted
prevented adequate drainage to the street.
The trees had a significant amount of deadwood
and cracked and the gutter was uneven, which
Magnolias typically have a large root mass close to the surface and often many of the roots are
exposed. It has been my experience that root pruning, removal or physical damage to the roots
causes significant decline and harm to otherwise healthy magnolias.
In addition, cutting roots on both sides of the trees would compromise the stability of the trees.
After considering all the information gathered (topping, deadwood, decay, potential root pruning
on both sides of the tree) and the "Criteria for City Street Tree Removal" form, I determined to
remove these trees and have them replaced with appropriate trees for the planting area.
I recommended that the existing magnolias be removed by City Crew, and that the stumps be
removed by the contractor. I also recommended that the planting area be increased to accept a
larger variety tree, and that 24" box size trees be planted as replacements. The project removed
the stumps, replaced the sidewalk and curb/gutter and replanted 5 24" box Gingko biloba trees.
Gingko trees are recommended under utility wires for their structure that is easily trained around
wires.

TREE EVALUATION
Person Reporting: Bob Disco
Details of Tree:
Genus: Magnolia
Species:
Common Name: Magnolia
Approx. Age: 50+ , Height: 20 DBH: 15", Cir. ', Crown:'
Tree Location: 190* Broadway
Date Sept. 15, 2011
Title: Park Supervisor
1. Assignment: Evaluate for removal due to sidewalk replacement
2. Observations:
Structural Defects: Wounds, topped, dieback, all trees in decline.
Soft/Root Condition: Tree is growing in a planter strip surrounded by concrete, Roots are
lifting sidewalk and curb and gutter.
Injuries: Growing under wires and topped by PG& E
History of free/site. none
3. Analysis / Testing: All analysis and testing were done visually without any injury to tree.
Conclusions and Discussion: As part of the building permit, the sidewalk and curb and gutter need
to be replaced. I was called out to inspect roots. All trees have an extensive root system that is
lifting the sidewalk and curb. Root trimming would eventually cause sever damage to trees, and,
because roots on both sides of trees need to cut, tree will decline further and future stability of
trees will eventually be compromised.
It is my opinion that the trees should be removed because of the root damage they will endure
and replaced with new trees once the sidewalk and curb have been installed.
Property owner will remove stumps and plant new trees as part of building process.

Urban Forest Management Plan
Policy for Expanding Width of Planter Strips to Accommodate Larger Canopy Trees
Background:
The City of Burlingame is committed to creating a larger tree canopy throughout the community
and has revised the official street tree list to include only those tree species with "the tallest,
most significant canopies". In approving the revised street tree list in October of 2008, the City
Council recognized that the more expansive root systems of larger -scale trees can disrupt city
sidewalks. The City Council therefore directed staff to explore opportunities to widen planter
strips to accommodate the root systems of the larger scale trees.
Planter Strip Policy:
Based on this direction, Parks and Recreation, Public Works, and Community Development staff
have developed the following "Planter Strip Policy" to apply to the construction of new homes
and additions to homes which are considered to be substantial construction as determined by the
Chief Building Official:
For new homes built in Burlingame, or when substantial construction is
performed on existing homes, property owners may be required to increase
(maximize) the planter strip width for the purpose of accommodating root
�- systems of large canopy trees.
Policy Guidelines:
This requirement is triggered when, during the plan check process, Public Works staff determines
that the applicant's project is subject to rehabilitating the frontage of the property including
replacement of the existing sidewalk. On many residential streets in Burlingame, there is
additional public right-of-way located between the existing sidewalks and the private property
line. This additional right-of-way varies from street to street and ranges from no additional right-
of-way to as much as five or six feet.
For projects where a new sidewalk is required, Public Works staff will also determine if there is
adequate right-of-way available to reconfigure the sidewalk to allow for a wider planter strip. If
there is, Parks and Recreation staff will make a determination on whether it is an appropriate
situation to implement this policy.
Parks Department staff will provide comments to the applicant on the preferred method of
satisfying the requirement. There are two ways that this policy requirement can be satisfied. The
planter strip may be widened along the entire width of the property, or the planter strip may be
widened at the location of the street tree(s) only. A photo of a planter strip widened at the
location of street trees is shown below. City staff must approve the final sidewalk alignment.
Urban Forest Management Plan
Policy on Expanding Width of Planter Strips to Accommodate Larger Canopy Trees
The applicant's landscape plan is required to include large canopy street trees within the planter
strip. The applicant will be required to contact the Parks Division office at (650) 558-7330 to
obtain an appropriate tree list and a no fee permit to plant one or more 15 gallon size trees as
spacing is available, at the conclusion of the project. The tree planting requirement will become
part of the "final inspection" on the project.

URBAN FOREST MANAGEMENT PLAN
Sidewalk Impacts and Replacement
Damage to urban infrastructure by tree roots is a significant problem in cities throughout the
`—" world. In the United States virtually every city has sidewalks, curbs, and gutters that have been
cracked, uplifted by tree roots, or both. Damage to infrastructure elements are not only costly to
repair, but they represent liability risks that can't be ignored. In addition, many trees (typically
repeat offenders) are removed because of infrastructure- related damage. In California this is the
second most common reason for tree removal. Collectively, tree loss, infrastructure repair costs,
and liability issues make this a significant problem that merits close attention from arborists,
urban foresters, planners, and engineers. (L.R. Costello 2005)
M
If any sidewalk near or around City trees are scheduled to be repaired, a City arborist, supervisor
or staff member must be notified before roots are cut or sidewalk is replaced.
The following shall be considered when replacing sidewalk damage that is caused by tree roots:
• Health and Structure of tree.
Future cost or damage to sidewalk.
If the tree is deemed healthy and structurally sound, several sidewalk_ design alternatives will be
recommended to increase the planting space for. the current tree and future trees.
Curving sidewalks — When at all possible, increasing the City right-of-way toward the
homeowner's property for the minimum ADA requirement will be encouraged. This will
increase the growing area for the current tree, protect roots, and provide a larger planting
area for future large -stature tree species.
Ramping - Where root pruning is not an option, ramping may be the only alternative to
avoid root damage and tree preservation. Ramps must not exceed the requirements for the
American with Disabilities Act.
Root Barriers — Root barriers can be placed in strategic locations to delay sidewalk
damage or damage to landscape. City staff can suggest areas where root barriers would
be useful.
