FROM: Jay D. Walter, Director of Public Works I-W
Prepared By: Manny Guzman
SUBJECT: UTILITY TRENCH REPAIR 2009-10 PROJECT SPECIFICATION NO.
90965
RECOMMENDATIONS
1. Approve plans and specifications for the Utility Trench Repair 2009-10 Project, Specification
No. 90965.
2. Authorize staff to advertise for bids and the City Manager to award the contract if the lowest
responsible bid is within the Engineer's Estimate of$179,530.
DISCUSSION
Throughout the year, Utilities Department staff makes emergency repairs to water pipelines under
City streets. Once these repairs are made, the trenches are backfilled and temporary asphalt patches
are placed at the surface of the road. These temporary patches are then replaced with a stronger and
more permanent asphalt patch performed under separate contract.
The Public Works Department accumulates a list of the temporary patch locations from the Utilities
Department and issues a construction contract periodically to make the permanent repairs. This
project will repair approximately 188 trenches throughout the City. An advantage to this approach
is that the City gets a better price for this work by combining multiple locations and permanent
repairs under one contract. A complete list of locations is included in the attached Special
Provisions for this project.
CONCURRENCES
The Community Development Department has given this project a categorical exemption from
environmental review.
FISCAL IMPACT
The 2009-11 Financial Plan, Appendix B, pages 3-71 to 3-77, estimates an annual cost of
$170,000 from the Water Distribution budget to support Utility Trench Repair projects. Because
we are doing more trench work than expected a greater total surface area will be repaired,
therefore the Engineer's Estimate is slightly higher on this project than the budget allocated for
this project.
