STAFF REPORT
To: Mayor and Members of the City Council
Attention: Keith R. Till, City Manager
From: Stephen G. Badum, Director of Public Works/City Engineer
Subject: COVE AREA STORM DRAIN REPAIR,
PROJECT NO. 666
GENERAL DESCRIPTION
The proposed City Council action will approve the plans and specifications, approve a resolution making findings regarding the urgency of the proposed repair work, and authorize Staff
to expedite the bidding process so that a contract may be awarded on November 27, 1995.
DISCUSSION:
Last winter, the City experienced extreme flooding conditions at several locations throughout the City as a result of severe storms. The residential area that is served by the existing
storm drains at Emerald Cove Way and Crystal Cove Way experienced severe flooding due to the intensity of the storm and the partial failure of the existing drains. City staff assessed
the damage and made an application to the Federal Emergency Management Agency (FEMA) to fund the necessary repair work. Upon funding authorization from FEMA, the design and construction
would proceed. However, the City was notified in September that the funding through FEMA would not be approved.
Due to the pending winter storm season, the design of a repair project was expedited. The existing drain system at each location includes twin 100’ long, 22”x 18” corrugated pipes
with a curb level inlet that originally conveyed flow to an earthen ditch adjacent to Pacific Coast Highway. The pipes are within a narrow easement between the existing homes. Today,
the pipes connect to a 78” reinforced concrete pipe storm drain, but the relatively flat grade of the original corrugated storm drains impedes the flow. The proposed repair project
will replace the existing twin corrugated pipes with one 30” high density
polyethylene pipe (HDPE) and standard concrete catch basin at each location. The new design maximizes flow and is hydraulically superior to the existing storm drain system. Failure
to repair the storm drains in advance of potential winter storms may result in flooding problems and erosion of property due to the failed portions of storm drain pipe.
The plans and specifications were completed by Willdan Associates under the City’s annual engineering services retainer. The proposed repair project for both storm drains is estimated
to cost $50,000. Due to the anticipated FEMA funding, funds were not budgeted within the 1995/96 fiscal budget for this project. The necessary funds required to construct this project
could be transferred from the Beach Sand Replenishment program since the Federal erosion control project has been deferred. The balance remaining in the project fund should be sufficient
to deal with any emergency shoreline erosion needs for this winter season.
RECOMMENDATION
Staff recommends that the City Council approve the plans and specifications. The City’s charter authorizes City Council to award contracts without advertising for bids, if such work
is deemed by the Council to be of urgent necessity for the preservation of life, health, or property, and is authorized by resolution containing a declaration of the facts constituting
such urgency. Due to the urgency of this repair project, staff additionally recommends that the Council pass a resolution declaring emergency conditions and direct staff to proceed
with the contract award process without advertising for bids. With the Council’s approval, four pre-qualified contractors will be asked to submit sealed bids by November 22, 1995.
City Council could approve the necessary budget amendment and award the contract to the lowest responsible bidder at the November 27, 1995 meeting. It is hoped that work could be
completed within the first week of December.
