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 Ficus Parkway Street Tree Maintenance October 14, 2003 Page 2 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. Prepared by: F. Johh F. Conway Urban Forester Submitted by: ` - David E.
