PROJECT DESCRIPTION
The operational characteristics of the City's water system were reviewed during the
preparation of the City's Water Master Plan and it was determined that several of the
City's major pressure reducing stations (PRS) serving the Peninsula and the low -lying
islands are in need of replacement.
The replacement of the PRS at Bayside Drive and Marine Avenue was identified by the
Master Plan. The original structure for this facility was constructed in 1957. Access to
the facility requires blocking traffic lanes on Bayside Drive or Marine Avenue. In
addition, the piping to the structure is approximately 15 -feet deep. If a water main break
occurs in this area there would be major impacts to the traffic on and off Balboa Island.
The project involves relocating the PRS to the northwest corner of the intersection and
installing the piping at normal depths. A new vault would be installed in the sidewalk
adjacent to the corner landscaping at the entrance to the Pavilions shopping center
providing better access for monthly maintenance and minimizing impacts to the public
during construction of the PRS (see attached exhibit). The new piping would improve
water supply to Balboa Island and the Balboa Peninsula through the Washington Street
Bay crossing.
FUNDING AND PROJECT SCHEDULE
There are sufficient funds available in the Water Enterprise Fund under Capital Project
Account No. 7503- C5500089 for award of Contract No. 3418. The project construction
start date would not be until after September 10, 2001, to avoid impacts with the
summer traffic. The Contractor is also required to coordinate with the Balboa Island
Bridge Beautification project scheduled to be constructed at the same time. Both
projects should be completed before Thanksgiving.
Respectfully submitted,
