AGENDA REPORT
DATE: March 12, 2007
TO: Honorable Mayor and City Council
THRU: Greg Beaubien, Interim City Manager
FROM: Mark Vukojevic, P.E. Director of Public Works/City Engineer
SUBJECT: RECEIVE AND FILE - WINTER SAND DIKE (BERM)
SUMMARY OF REQUEST:
Receive and file the removal of the winter sand dike.
BACKGROUND:
e
Historically, the residents along the beach between the Anaheim Jetties and the pier are
subject to wave inundation during storms. The threat of washouts or flooding is lessened
by the annual construction of a 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.
On September 22, 2003, the City Council received and fIled a report prepared by Moffat
Nichol Engineers regarding the construction and removal of the annual winter sand dike.
At that meeting the City Council directed staff to implement the following timeline:
o Start construction of the dike after November 1 with completion anticipated by
mid November.
o Remove the dike by March 31.
o During El Nino years, start construction of the dike so it is complete by
November 1 and leave in place until mid April.
e
The weather patterns currently being experienced by Southern California suggests that
the dike removal should occur the last week of March. The removal of the sand dike will
most likely begin on Monday, March 26, 2007 and should take one week to remove. In
the event of imminent storm or coastal wave events, removal may be postponed an
additional week. Cattrac Construction, the City's on-call contractor, will perform
removal of the berm, and Moffatt & Nichol Engineers will provide inspection and
monitoring services.
Agenda Item G

e
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. The
information analyzed is not exact and there always looms the chance for an occurrence of
events similar to September 1997." Staffhas also received input from a minority of the
public that desire additional storm protection, and that are against loss of beach views.
The current plan intends to strike a balance with community desires and protection from
unpredictable natural events.
FISCAL IMPACT:
There are sufficient funds within the contract professional services budget of the
Tidelands Beach/Pier Account. It is anticipated that the cost of the removal of the sand is
approximately $30,000.
RECOMMENDATION:
Receive and flle the removal of the winter sand dike.
