CITY COUNCIL STAFF REPORT
Item No. io
October 14, 2003
TO: HONORABLE MAYOR AND MEMBERS OF THE CITY COUNCIL
FROM: General Services Department
David E. Niederhaus, Director, 949 - 644 -3055, dniederhaus(a)-city.newport -
beach.ca.us
SUBJECT: Parkway Ficus Tree Maintenance
ISSUE:
Should the City provide additional funding for parkway Ficus tree maintenance to offset
liability and damage to infrastructure?
RECOMMENDATION:
Approve the attached budget amendment for $60,000 for the installation of root barriers,
tree trimming, and root pruning of mature parkway Ficus trees located throughout the
City.
DISCUSSION:
Background:
During consideration of the award of a concrete contract at the September 9, 2003
Council meeting, Councilperson Webb requested staff prepare a budget amendment in
the amount of $60,000 to address the annual maintenance of Ficus trees.
There is currently a total of 2,200 Ficus trees in the City's Urban Forest. This number
represents 7.5% of the total City tree population. Of this percentage, 755 Ficus trees
are parkway trees that are considered mature and root intrusive. During Fiscal Year
2002 -03, the City Council approved a supplemental budget of $50,000 for tree
trimming, root pruning, root barrier installation, and parkway restoration at 300 Ficus
tree sites as a result of a staff presentations and recommendations during the first six
months of 2002. The funding was not continued in the current fiscal year.
Discussion:
Since 1998 there has been 126 tree related claims filed against the City, totaling over
$1,000,000 in private property damage. Of this claim value, 58% or $580,000 was due

to damage caused by Ficus tree roots. This funding will be used to supplement the
sidewalk, curb, and gutter repairs in the City. If this funding is not approved, expending
hardscape repair funds to perform tree root remediation work will reduce the amount of
sidewalk, curb, and gutter replaced in the current and future concrete contracts.
It should be noted that the installation of root barriers, tree trimming, and rooting pruning
that was completed in FY 2002 -03 has significantly reduced complaints, claims, root
intrusions, and property damage issues in the areas in which the work was performed.
Whether the positive results are temporary or long- lasting remains to be seen.
As a matter of information, annual Ficus tree trimming results in a significant reduction
in the growth and expansion of tree roots.
Environmental Analysis:
Not applicable.
Funding Availability:
The requested funds are not available in the current budget. A budget amendment form
is attached.
