SUBJECT: Material Removal Project, Prefumo Creek at Los
Osos Valley Road, City Plan No. P-49H.
CAO RECOMMENDATION: By motion, approve plans and specifications for
°Material. Removal. Project, Prefumo Creek at Los
Osos Valley Road, City Plan No. P-49H° and
authorize soliciting of bids and contract award
by the CAO, if the lowest bid is within the
Engineer's cost estimate.
BACKGROUND:
Storm waters from Prefumo Creek wash large quantities of silt and
gravel into the Prefumo Arm of Laguna Lake. This material must be
removed to prevent clogging of adjacent storm drainage structures, and
to prevent flooding of streets and homes.
This area was dredged by the County Engineering Department in 1984
using Zone 9 funds. In 1986 the City contracted for the removal of an
additional 4,000 cubic yards of material.
DISCUSSION:
At this time, approximately 8,000 cubic yards of silt and gravel need
to be removed from the Prefumo Arm of Laguna Lake to return flow lines
to the levels that were achieved in 1984 and to prevent future build up
of silt from causing flooding.
Zone 9 Flood Control District will reimburse the City for the cost of
this project. The dredged materials will be delivered to the county
for use on road projects.
COORDINATION:
The Community Development Department has issued a declaration of
negative environmental impact. The State Department of Fish and Game
and the Corps of Engineers are processing permit applications. No work
will be accomplished until the approved permits are received. This
project is being processed to bid while the permits are being processed
in an effort to complete the work before the rains this year.
