SUBJECT:
Waterline Improvement Project: Higuera St. - Broad to Osos, City
Plan No. S-05P
CAO RECOMMENDATION:
By motion, approve the plans and specifications for Waterline
Improvement Project: Higuera St. - Broad to Osos, City Plan No.
S-05P, and authorize soliciting of bids and contract .award by the
CAO if the lowest responsible bid is within the Engineer's cost
estimate.
DISCUSSION:
The waterlines in the downtown area are very old and in a deteriorated
condition. Frequent breakages disrupt service. These lines are also
undersized and do not provide adequate fire flow to meet current
standards.
The replacement of this waterline is also a condition of the building
permit for the construction of the "Copeland Project" at 879 Higuera
St. to provide adequate fire protection.
Another condition of the "Copeland Project" is participation in the
cost of the project, the amount of which has not been determined at
this point.
As this project will be in the core of the downtown, a number of
mitigating measures and stringent requirements will be included to
minimize the disruption to business activities (see attachments) .
The conditions are designed to ensure that Thursday night activities
will not be impacted, and that parking will be maintained to the
maximum extent possible.
During construction, the City proposes to provide special promotions
for the business community affected by this project. This program is
still being worked on by staff, and should be ready for Council review
prior to December. The BIA will be a participant in designing the
program.
CONCURRENCE:
Staff has discussed this project with the BIA. Staff has met with the
Thursday Night Activity Committee and included conditions in the
project specifications to allow the Thursday night activities to
continue, and be impacted as little as possible. The winter timing of
the project was recommended by the BIA after surveying their
membership. The BIA has reviewed the attached list of conditions and

we have received concurrence from Lynn Block. Weather problems and
impacts were explained.
The Community Development Department has determined that this project
is categorically exempt from further environmental review.
FISCAL IMPACT:
Engineer's Estimate: $150, 000
7% Contingencies: 10, 000
Potential Bonus: 20. 000
Total: $180, 000
In order to encourage early completion of the project, a bonus will be
paid to the Contractor at the rate of $2, 000 for each day earlier than
the completion date that the project is finished, up to a maximum of
$20, 000. Failure to finish on time or to work on a working day can be
penalized at a cost of $1, 000. 00 per day.
The Engineer's Estimate for the project is $150, 000. The CIP for
1992/93 (page E-7) includes $600, 000 for water main improvement
projects. To date, $94, 000 has been approved for other water
distribution projects, leaving $506, 000 to support this project.
The City Council, at the June 30, 1992 meeting, determined that utility
projects go forward based on their independent funding.

PROJECT CONDITIONS AND REQUIREMENTS
Contractor's attention is directed to the fact that this project is
in the core of the Central Business District. Much concern has

traffic plan, and progress schedule to the City Engineer no

day or night, unless those materials are stored during
working hours, and are to be used completely during the day
in which they are stored.

case it must be used during the day that it is stored or
used the day after the night it is stored.

proceed with the work with at least 75% of the normal labor
and equipment force engaged in operation(s) for at least
60% of the total daily time being currently spent on the
controlling operation(s) , Contractor will be assessed a
penalty in the sum of $1,000.00, unless excepted by
inclement weather or other condition beyond the control of
