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:
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 had approved a plan, based on Moffatt & Nichols
Engineers assessment report, to implement the following recommendations:
❑ Start construction of the dike after November 1 with completion anticipated by
mid November.
❑ Remove the dike by March 31. (Lead time for removal usually takes 2 weeks.)
❑ During El Nino years, start construction of the dike so it is complete by
November 1 and leave in place until mid April.
During the May 2005 Mid -Point Budget Adjustment, City Council also approved an
additional expenditure of $100,000 for sand back passing from the west beach to the east
beach to maintain sand at the east beach. In consideration of the above mentioned
recommendations, the additional work required for the back pass operation and weather
activity experienced last year, it is recommended that the berm and sand back -pass
operation begin in mid - October. 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 to take 4 to 6 weeks to

a
complete. Separate notices will be delivered to Seal Way residents regarding the start of
the project.
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
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 of future events
similar to September 1997. Staff has 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 Capital Improvement Program FY 05/06, Project 50194, in
the amount of $250,000 for the sand back -pass project and winter sand dike construction
and removal. 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.
