TO: BOARD OF SUPERVISORS, as the Governing Body of the Contra Costa County Flood
Control and Water Conservation District
FROM: J. MICHAEL WALFORD, CHIEF ENGINEER
DATE: MAY 12, 1992
SUBJECT: SOIL EXCAVATION AGREEMENT-DRAINAGE AREA 105,
DEER CREEK DETENTION BASIN - BRENTWOOD AREA - PROJECT (7590-6D8515)
SPECIFIC REQUEST(S) OR RECOMMENDATION(S) & BACKGROUND AND JUSTIFICATION
I. Recommended Action:
APPROVE Soil Excavation Agreement for the Deer Creek Detention Basin with Morrison Homes
Northern Division, a division of George Wimpey, Inc., and AUTHORIZE the Chief Engineer to sign
the Agreement on behalf of the District.
II. Financial Impact:
The Agreement commits the District to pay Morrison Homes Northern Division, $2.00 per cubic
yard for the removal of between 20,000 and 40,000 cubic yards of soil material from the Deer
Creek Detention Basin in Brentwood. The funding source is Flood Control Drainage Area 105.
III. Reasons for Recommendations:
Informal bids were recently solicited in an attempt to sell the material in place. No positive bids
were received. All bids were rejected, the lowest being $2.50 per cubic yard. Subsequent to
the rejection of the bids, the purchaser advised he had an immediate need for the material and
would take the material at a lower price. Development of the detention basin requires that this
material be removed and it appears the best price to the District can be achieved in cases like
this where immediate commitments can be made when the material is wanted. The district
intends to contract for the removal of the material on a first-come, first-served basis at $2.00 a
yard to any qualified excavator until the basin is completed.

IV. Background:
The District has estimated that if there were no demand for soil material for offsite use, the cost
to excavate the basin could run between $4 and $5 per cubic yard. While no positive bids were
recently received for the basin excavation, the lowest non-conforming bid was $2.50 per cubic
yard. Contracting to remove the material on an as-needed basis at $2.00 per cubic yard
represents a considerable savings to the District over estimated costs if there is little or no
demand for the material. It is estimated that approximately 220,000 cubic yards of material will
have to be removed.
V. Consequences of Negative Action:
If the award is delayed, there is a risk that the material will not be in demand when the District
wishes it removed. This would result in an increased cost to the District. Since the amount to
be removed is substantial, the cost increases could be substantial.
