DISCUSSION:
On June 25, 2002, the City Council authorized the award of the Buck Gully, Linda Isle,
and Carnation Pump Station Rehabilitation contract to Caliagua, Inc. The contract
provided for the upgrade and renovation of the Buck Gully Wastewater Pump Station
located near Little Corona Beach off Ocean Boulevard in Corona del Mar.
The project involved the construction of a new pump room, installation of new pumps
and controls, demolition of the existing above ground control room, and construction of
a new roof structure at the same elevation as the adjacent pedestrian walkway. In
addition, new drainage facilities were constructed along with new concrete walkways to
the adjacent Little Corona restroom facilities. Replacement of the Buck Gully pumps
included the purchase of a quieter backup generator.
The Carnation and Linda Isle Pump stations were also included in the Buck Gully
contract. The upgrades for these two stations included new hatches to allow better
access to the stations and electrical upgrades, including emergency generator
connections. A new bypass pump connection vault was also installed at each station.
Since the Buck Gully project includes the same type of hatches, electrical controls, and
bypass components, construction cost savings were realized by constructing these
three stations as one contract. The contract has now been completed to the
