CITY OF SAN BERtORDINO - REQUEST Q)R COUNCIL ACTION
STAFF REPORT
Construction of the retention basin at Meechum Canyon, as
part of the Chestnut Avenue Storm Drain System, will provide'
protection from possible flooding of the area.
The water chute at the top of the retention basin,
directly above the spillway, was constructed to provide the
retention basin with an overflow mechanism, preventing the walls
of the retention basin from being breached.
Concrete and rip-rap were originally included in the
plans, in order to control erosion and prevent potential damage
~n case of an overflow from the basin. However, these items were
deleted in a cost saving measure. The Contractor has stated that
he will not assume responsibility for any damage to the spillway,
if the concrete and rip-rap are not constructed.
The project is nearing completion, and there are suffi-
cient contingency funds to finance this extra work. Installation
of the concrete and rip-rap will reduce the City's exposure for
maintenance costs in the future.
The Contractor has quoted a price of $19,895.00 for con--
structing the concrete and rip-rap protection at the water chute.
We have reviewed the quoted price, and feel that it is fair and
reasonable for the work involved.
There is a current balance of $335,711.81 in contingency
funds, that will be used to finance the cost for this extra work.
We recommend that the Contractor be authorized to perform
these items of extra work.
