SUBJECT: WATERLINE IMPROVEMENTS- VARIOUS LOCATIONS,
SPECIFICATION NO. 90788
RECOMMENDATIONS
1. Approve the plans and specifications for the "Waterline Improvements, Various Locations"
Project, Specification No. 90788.
2. Authorize staff to advertise for bids and authorize the City Manager to award the contract if
the lowest responsible bid is within the Engineer's Estimate of$377,644.
DISCUSSION
Replacement of water distribution pipes and related facilities is an ongoing program to replace
aging, substandard and deteriorating infrastructure. This program has three objectives:
1) Ensure reliable water services
2) Reduce the need for emergency repairs
3) Enhance available fire flows
Based on priorities set by the Utilities Department, certain waterlines have been selected for
replacement as shown on Attachment 1. These water lines have seen an increase in required
maintenance and emergency repairs in recent years, as a result of their age. The assumed useful
life expectancy of water lines is fifty years. The waterlines proposed for replacement with this
project were originally installed in 1942 or earlier. Replacing these waterlines will result in lower
costs and reduced customer impacts that would otherwise be associated with emergency repairs.
CONCURRENCE
The Community Development Department has granted a Notice of Exemption because of the
potential for minimal environmental impacts.
FISCAL IMPACT
Waterline improvements have been identified in the Preliminary 2009-11 Financial Plan
Appendix B, page 3-71 and 3-77, for Water Distribution System Improvements. Funding for this
project is available in the Water Distribution System Improvements Main Account, which has a
