SUBJECT: SAN LUIS DRIVE WATERLINE REPLACEMENT PROJECT,
SPECIFICATION NO. 96235
CAO RECOMMENDATION
1. Approve the plans and specifications for the "San Luis Drive Waterline Replacement
Project", Specification No. 90235.
2. Authorize Staff to advertise for bids and authorize the CAO to award the contract if the
lowest responsible bid is within the Engineer's Estimate.
3. Accelerate funding in the amount of $187,250 from the Distribution System Improvements
Account in 2006-07 to 2005-06 in order to fund this project.
DISCUSSION
Replacement of water distribution pipes, mainlines 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; and
3) enhance available fire flow.
Based on priorities set by the Utilities Department, the waterlines in San Luis Drive neighborhood
have been selected for replacement.
The residences of the San Luis Drive neighborhood have waterlines and water meters located in
backyard easements. Some of these waterlines are over 50 years old and present challenges for
Staff during the course of maintenance, repair and meter reading.
This project involves installation of new waterlines in San Luis Drive, Corralitos Avenue, Alisal
Avenue, and Alta Street so that existing waterlines located in backyard easements can be
abandoned. Water services and meters for thirty-eight of the properties must then be reinstalled'in
the front or the side of the property and abandoned in the rear of the property. The location of each
new water service has been researched and discussed with each property owner. Right of Entry
agreements have been executed with all required homeowners.
CONCURRENCES
The Community Development Department has filed a Notice of Exemption for this project.
FISCAL IMPACT

funding is not currently available in 2005-06. This project will be funded from the Distribution
System Improvement Account, which has a current balance of$990,000 and it is proposed that
the project be allowed to move forward with $187,250 in funding accelerated from the 2006-07
budget. Based on the project timeline, with the construction bid award tentatively scheduled for
June 29, 2006, it is likely that expenditures will occur after July 1St; in the 2006-07 fiscal year.
Future water distribution projects have been reprioritized to account for the revised budget
availability in 2006-07.
Engineer's Estimate: Construction Costs $ 1,015,000
Construction Contingencies $ 152,250
Materials Testing $ 10,000
Total $ 1,177,250
Typical Capital Improvement Plan projects construction contingency amounts are 10% of the
engineer's estimate.. Construction contingencies for this project are requested at 15% due to the
increased likelihood of unforeseen conditions and the increased difficulty working on private
property. Additionally, portions of the asbestos-cement waterline intended to be replaced with
this project where unable to be located. Public Works potholed the area as well as used ground
penetrating radar in an attempt to discover the actual location of the waterline without.success.
Plans were prepared using record information so some redesign to fit actual built waterline
locations is expected.
