AGENDA REPORT
DATE: August 8, 2005
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: APPROVAL OF PLANS AND SPECIFICATIONS FOR
SAND RETENTION GROIN REPAIR, PROJECT No.
50147
SUMMARY OF REQUEST:
The proposed City Council action will approve the plans and specifications and authorize
Staff to initiate the bidding process for Sand Retention Groin Repair, Project No. 50147
BACKGROUND:
After the construction of the harbor jetties in Long Beach (Alamitos Bay) and at the U. S.
Naval Weapons Station (Anaheim Bay), natural beach sand management was
permanently altered. Waves reflected by these jetties caused severe beach erosion on the
East Beach. To reduce the rate of erosion to manageable rates, a concrete sheetpile groin
(750 -ft) was constructed in 1959 adjacent to the Seal Beach Pier. The concrete sheetpile
groin retains the shifting sand, which results in a wider beach that provides increased
protection to coastal structures from wave and flood damage.
On its February 23, 2004 meeting, the City Council received and filed additional
information regarding the status of the Sand Retention Groin Rehabilitation Project. In
addition, Council was briefed on the 2001 Groin Feasibility study, which helped secure
the grant funding from the Department of Boating and Waterways (DBAW). Moffat and
Nichol Engineers, the City's Coastal Engineering Consultant has prepared a
Rehabilitation Study also known as a preliminary design report for the Sand Retention
Groin Rehabilitation Project. Staff and the consultant have worked closely together in
providing the information on the repair alternatives, environmental impacts, and permit
requirements. The consultant has also discussed the project with the California Coastal
Commission and the Department of Boating and Waterways.
The Study recommended alternative 7 as the most feasible alternative. This includes the
reinforcement of the outer 252 -feet by the installation of new concrete sheet piles on one
side, installation of new sheet piles on the opposite side of the damaged piles,
construction of a new cap for 350 -feet and repairing the remainder of the cap. However,
construction will require the use of large cranes and the closure of the Pier during
Agenda Item t/
construction. The study has also identified the need for sequential permits from Regional
Water Quality Control Board (RWQCB), California Coastal Commission (CCC) and US
Army Corps of Engineers (USACE). A California Environmental Quality Act (CEQA)
review also indicates the project will likely require a Mitigated Negative Declaration as it
may cause environmental impact that can be mitigated. The Mitigated Negative
Declaration is presented to the City Council at this meeting as a separate report. Permits
are estimated to be issued by the three agencies by October 2005.
The construction repair of the groin is coordinated with the Ruby's Diner renovation. It
is scheduled to occur during low -usage of the pier. It is estimated to begin in November
2005 through February 2006.
FISCAL IMPACT:
Funds are available within the Project No. 50147 of the approved Capital Improvement
Program. The estimated total cost of the project including design, environmental,
permitting, construction and inspection is $1,067,000 which is funded by $800,000 from
DBAW. $267,000 was funded from the undesignated general fund reserve as authorized
by City Council on February 10, 2003. No additional work will be performed unless
adequate funding is available in the project budget. Any funds remaining at the end of
this phase of the project will be returned to DBAW and the City's General Fund.
RECOMMENDATION:
Staff recommends that the City Council approve the plans and specifications and
authorize Staff to initiate the bidding process for Sand Retention Groin Repair, Project
No. 50147
