COUNCIL AGENDA REPORT
FROM:
Dave Romero, Director of Public WorksITw
William Hetland, Utilities Director
Prepared by: Barbara Lynch, Engineering Assistant
SUBJECT:
Sewermain Improvement: Sinsheimer School Easement near San Marcos
Ct. , City Plan No. R20R.
CAO RECOMMENDATION:
By motion, approve plans and specifications for Sewermain
Improvement: Sinsheimer School Easement near San Marcos Ct. , City
Plan No. R20R, authorize soliciting of bids and contract award by
CAO if the lowest responsible bid is within the Engineer's
estimate.
BACKGROUND:
The existing sewermain at this location is suspended over Acacia Creek.
It is held in place with two concrete piers imbeded in the creek bank.
The existing line is leaking in some places and staff is concerned
about the possibility of leakage into the creek. One of the manholes
has significant root intrusion and will also be replaced. The proposed
project will realign the sewermain to place it below the creek flow
line. This will prevent leakage and remove the pipe and piers from the
creek bank area. The replacement of the manhole will reduce
infiltration of water into the system.
Alternatives:
1) Proceed with the replacement of the damaged line, preventing
further leakage.
2) Do not proceed with the replacement of the damaged line at this
time.
FISCAL IMPACT:
The engineer's estimate for this project is $23,000. The CIP for
1989/91 (page D-22) includes $420,000 for sewermain improvement
projects. $96,570 has been spent, leaving $323,430.
RECOMMENDATION:
By motion, approve plans and specifications for Sewermain Improvement:
Sinsheimer School Easement near San Marcos Ct. , City Plan No. R20R,
authorize soliciting of bids and contract award by CAO if the lowest
responsibele bid is within the Engineer's estimate.
