DISCUSSION
Background
The existing Bishop water storage tank has been identified in the Water System Master Plan as a
system deficiency. The Water System Master Plan recommends upgrading the existing water
storage tank. Increasing the storage capacity at this site will provide increased fire protection
and enhanced operational reliability and flexibility.
On October 7, 2003 the City Council authorized an agreement with Black and Veatch
Corporation to prepare plans and specifications for a new 750,000 gallon water storage tank.
The new tank will require a larger site. Staff pursued and obtained from the County of San Luis
Obispo a larger easement for the new tank and for construction. On December 6, 2005 the City
Council authorized the purchase of the easement. On December 23, 2005 the easement closed
escrow and was recorded.
Current
The City's design consultant has completed the plans and specifications for the new tank and staff is
seeking authorization to seek bids and award a contract if the lowest responsible bidder is within
available funding.
Due to the specialized nature of this construction, staff anticipates using an outside inspection
service for portions of the work, in particular the welding of the tank and coating application.
General grading, structural work and landscaping will be overseen by engineering staff.
CONCURRENCES
On February 2, 2004; January 3, 2005; and February 22, 2005 the Architectural Review
Committee reviewed the proposed new tank for visual, aesthetic and landscaping issues. On
March 7, 2005 the Architectural Review Committee granted final approval and certified the
environmental document for the new Bishop water storage tank.

The Abandoned Foothill Pump Station project is completed. The other recommended funding
transfers have to do with timing and/or alternative funding sources. The Transfer Pump Station
Upgrade remains an important project and will be funded as part of the Water Treatment Master
Plan Improvement Project (addressed in a separate report at this meeting). The $180,000 from
Water Mains Airport/Margarita is from the 2004-05 budget, while $156,000 in 2005-06 budget
remains available for water mains in the Airport/Margarita area. The Airport Area projects will
fund waterline installations when new roadways (Prado Road, etc.) are constructed in the Airport
Area. These projects were identified in previous budgets but actual timeframes for construction
of new roadways is unknown. These projects are funded through area specific impact fees for
the Airport/Margarita areas and will be included in future budgets based on estimated schedules
for roadway improvements in the area. The Retire Highlands Tank/New Rosemont PS project is
currently in the design phase. When more specific information becomes available on the
Highlands Tank/New Rosemont PS project, and if additional funding is required, staff will return
to Council at that time.
