Prepared by: Barbara Lynch, Engineering �Assistantl
SUBJECT:
Sewermain Improvement Project: Freeway 101 Easements, Toro and
Broad Streets, Specification No. 93-36.
CAO RECOMMENDATION:
By motion, approve plans and specifications for Sewermain
Improvement Project: Freeway 101 Easements, Toro and Broad Streets,
Specification No. 93-36, and authorize soliciting of bids and
contract award by CAO if the lowest responsible bid is within the
Engineer's estimate.
DISCUSSION:
This project is a combination of two separate sewerlines, Broad Street
under the freeway and a line paralleling the freeway near Toro Street.
The projects were combined to obtain a lower price per foot. The section
near Toro is identified in the CIP for completion this year. The Broad
Street section was scheduled for replacement previously but funding was
unavailable. This project will only address the portion of the Broad
Street line which crosses the freeway. The remainder of replacement will
be done as a future project as funds become available.
The two sewerlines are in a highly deteriorated condition: Both lines
need routine maintenance but are in such a condition that maintenance
personnel have ceased to clean them for fear of collapse. The Utilities
Department felt the projects would be good candidates for lining, a
technique which has been used in the past to recondition sewerlines in
areas not conducive to standard trenching methods. A lining material is
inserted into the sewerline and the pipe flooded with hot water. The
liner is forced against the existing pipe and hardens. The connection
points of the sewer laterals are then cut out with special tools, from
the inside of the pipe.
CONCURRENCES:
The Planning Department has given this project a categorical exemption.
FISCAL IMPACT:
The 1993-95 Financial Plan (page E-13) identifies $ 176, 000 for the
sewermain replacement program. Of this amount, $ 27,800 has been
identified for a prior project, leaving a balance of $ 148, 000 to support
this project.
Engineer's Estimate $ 79,000
Contingencies $ 5. 000
TOTAL: $ 84,000
Plans and Specifications are available in the Council Office for review.
