AGENDA REPORT
DATE:
September II, 2006
TO:
Honorable Mayor and City Council
THRU:
John B. Bahorski, City Manager
FROM:
Mark K. Vukojevic, P.E. Director of Public Works/City Engineer
SUBJECT:
RECEIVE AND FILE - WINTER SAND DIKE (BERM)
SCHEDULE AND OPERATIONS
SUMMARY OF REQUEST:
Receive and file the winter sand dike timeline and construction activities.
BACKGROUND:
e
Historically, the residents along the beach between the Anaheim Jetties and the pier are
subject to wave inundation during storms. This is lessened by the annual construction of
the sand "berm". The berm is routinely removed prior to the Easter Holiday except in
cases where possible inclement weather and wave events would make it prudent to leave
it in place for longer periods. Weather patterns are unpredictable and the City has
experienced flooding in the past when the berm was not in place.
In September of 2003 City Council approved a plan, based on Moffatt & Nichols
Engineers assessment report, to implement the following recommendations:
lJ Start construction of the dike after November I with completion anticipated by
mid November.
lJ Remove the dike by March 31. (Lead time for removal usually takes 2 weeks,)
lJ During El Nino years, start construction of the dike so it is complete by
November I and leave in place until mid April.
e
In the fall of 2005, 180,000 cubic yards of sand was back passed from the west beach to
the east beach. The next back pass project is scheduled for 2007. This year back passing
is not necessary. Cattrac Construction, the City's on-call contractor, will perform the
berm construction and removal and Moffatt Nichol Engineers will provide inspection and
monitoring services. The project is expected begin October 30, 2006 and take I to 2
weeks to complete.
As reported in the September 22, 2003 City Council report, "It is important to note that
any policy involving natural occurrences involve risk. Often elected officials have to set
Agenda Item G-
policy and protection based upon probability of occurrence, funding availability and .-
geographic locale. This report analyzed the probability of tropical events and does make .,
a recommendation that will be perceived as more favorable by the public. Note that the
information analyzed is not exact and there always looms the occurrence offuture events
similar to September 1997. Staffhas also received input from a small minority that they
desire the additional protection. The current plan intends to strike a balance with
community desires and protection from unpredictable natural events."
FISCAL IMPACT:
Funds are available within the Tidelands Beach Fund in the amount of $75,000 for the
construction and take down of the winter sand dike (berm). Any remaining funds will be
reprogrammed for other needed beach improvements or back to the General Fund.
RECOMMENDATION:
Receive and file the winter sand dike timeline and construction activities.
