SUBJECT: RAWLINGS RESERVOIR
RECOMMENDATION:
Receive and file.
BACKGROUND:
The recently completed Water System Storage Evaluation Study
surfaced several facilities which are in need of structural
rehabilitation. The subject facility, Rawlings Reservoir,
requires certain retaining wall rehabilitation that requires
immediate reconstruction.
DISCUSSION:
The retaining wall in question supports the southeasterly side
of the 4.7 million gallon Rawlings Reservoir located northerly
of Foothill Boulevard. This retaining wall is showing signs of
def lection/movement away from the reservoir structure. Total
failure of the retaining wall could result in failure of
reservoir structure resulting in potential property damage and
the welfare and safety of adjacent downstream residents.
Currently the Rawlings Reservoir is being operated at partial
capacity to reduce the potential for total failure. With the
marginal reservoir storage within the water system, it is
imperative that the retaining wall be reconstructed at the
earliest possible date so that the Rawlings Reservoir can be
returned to its maximum storage operation for domestic use and
fire flow needs.
Staff is proceeding on an emergency basis with the hiring of a
structural consultant for the design and preparation of plans
for the reconstruction of the retaining wall. Upon completion
of these plans, staff will proceed with a negotiated
construction contract for the reconstruction of the retaining
wall.
It is estimated that the wall replacement cost will be
approximately $290,000.00. Staff will return with a request for
a supplemental budget appropriation from the Water Capital
Improvement Fund once a final cost has been determined.
