Special Tree Removal Request- Holiday Road
Recommendation
PB &R Commission Agenda
Item No. _4_
November 1, 2011
Staff recommends that the Parks, Beaches and Recreation (PB &R) Commission approve
the removal of eighteen (18) Blue Gum Eucalyptus Trees located on the 2200 block of
Holiday Road.
Discussion
Following the tragic accident in September when a Blue Gum Eucalyptus (BGE) tree fell
and took the life of a motorist on Irvine Avenue, the City immediately hired an outside
certified arborist to work with staff arborists to evaluate the remaining BGE's in the City
(250 +) and determine the safety of these large trees. The contract certified arborist, R.
Dan Jensen & Associates, Incorporated, was given specific areas to evaluate first given
the density and location of the BGE's. These areas included Irvine Avenue, Fourth
Avenue in Corona Del Mar, Holiday Road, and the Castaways Park Bike/Pedestrian Path.
On October 5"', while the arborist was inspecting the trees on Fourth Avenue, another
BGE failed at Fourth Avenue and Goldenrod Avenue severely damaging three cars and
caused damage to a neighboring home. This tree failure was followed immediately by
the emergency removal of four additional BGE's in that area.
The report regarding the BGE trees on Holiday Road was recently completed and
submitted to the City. Arborists evaluate the health and potential failure of the tree based
on the following five criteria in the Tree Inspection Process:
1) Characteristics- size, age, and history
2) Health- foliage density, woundwood development, vigor
3) Site Conditions - landscape type, irrigation, obstructions
4) Potential Threats- use in failure zone, occupancy
5) Tree Defects- crown defects, lean
The information from this inspection process is used to rate each individual tree
according to ANSI (American National Standards Institute, Inc.) A300 Tree Risk
Assessment a. Tree Structure Assessment. The numerical ratings in determining the
potential risk for tree failure is as follows:
0 - 2 points: ZERO RISK
3 - 5 points: LOW RISK
6 - 8 points: MODERATE RISK
1
9 - 11 points: HIGH RISK
12 points: EXTREME RISK
Trees with a risk assessment of 11 or 12 should be removed immediately (emergency
removal). Trees in the 8 to 10 range should be considered for removal as soon as
possible, i.e. Commission meeting, etc. Trees with a 6 or 7 rating should be monitored
very closely.
The eighteen (18) BGE trees located on the 2200 block of Holiday Road were evaluated
in October, and fourteen (14) of these trees received a risk assessment rating of HIGH
RISK. The remaining four (4) trees scored in the MODERATE RISK category. Staff
is recommending removal of all 18 trees due to the fact that given the `windrow" method
of planting these trees (planting as close to each other as possible to deflect wind)
removing one tree may impact the health/root structure of surrounding trees.
With Commission's approval, staff will schedule the immediate removal of these trees.
Notices will be mailed to impacted residents and posted on the trees. The BGE's will be
removed at city expense and, following removal, the city will repair damaged irrigation
and place grass /sod on the disrupted area at city expense. However, the city cannot
replace gardens or other custom infrastructure such as fences, brick walls, fountains, etc.
Within the next 60 days, staff will work with each individual homeowner on selecting a
replacement tree. The replacement trees will be supplied and planted at city expense.
