STAFF REPORT
The plans direct the Contractor to grade the bottom of the
Cable Creek Flood Control Channel, downstream of the box culvert
being constructed at Little League Drive. This work was
necessary in order for the channel flowline to meet the invert
elevation of the new box culvert. These plans were prepared in
accordance with the San Bernardino County Flood Control
District' s requirements.
During the unusually heavy rain storms in January, the
channel bottom eroded below the rail and wire revetments along
both sides of the flood control channel. The District' s Inspec-
tor has directed that 1/4 ton grouted rock slope protection be
installed from the box culvert to a point 340 feet downstream, in
order to provent further damage from future storm flows.
The quantity of rock slope protection is estimated to be
182 tons. The Contractor has agreed to do this extra work for
the lump sum of $8, 558. 55, which is based upon the bid price of
$45/ton for grouted rock slope protection, plus 4j$ for another
move-in.
There is an available balance of $55, 824 . 25 in contin-
gencies that can be used to finance the cost of this change
order. Federal-Aid Bridge Replacement Fund will be used to
finance 80% of the cost for this extra work.
We recommend that Change Order No. Two be approved.
