SUBJECT: Resolution Accepting Completion of the Construction Contract for the Various

RECOMMENDATION
It is recommended that the City Council Adopt the Attached Resolution Accepting Completion
of the Construction Contract for the Various Locations Rock Slope Protection Project.
BACKGROUND
During the storm event of December 2005 to January 2006, excessive rains caused high velocity
flows in Petaluma River and other creeks. The incident scoured riprap under a 60"corrugated
metal pipe to the Petaluma River at the Turning Basin that collects stonn drainage from the B
Street neighborhood out fall; the embankment of the Old Redwood Highway Bridge abutment;
the embankment of the Washington creek near Noriel Trail; and a portion of river bank near
Copeland Pump Station.
This contract work for the four project locations is described below:
1. B Street 60" CMP Outlet Rip Rap Erosion Repair- F00111806/PW1118:
Excavation and placement of rock slope protection on bank of the Petaluma River around
the outlet of a 60 -inch culvert.
2. Rip Rap Repair below Old Redwood Highway- F00127706/PW1277:
Excavation and placement of rock slope protection on the abutment slopes under the Old
Redwood Highway Bridge in the City of Petaluma.
3. Noriel Trail Embankment and Stonn Drain Outlet Repair - F00242006/PW2420:
Excavation and placement of rock slope protection on the stream embankment at one
location upstream of the Noriel Lane walk bridge and two culvert outlets on the
downstream side of the bridge, together with miscellaneous permanent erosion control
and riparian planting measures.
4. Rock Slope Protection at Copeland Sewer Pump - F00332906/PW3329:
Excavation and placement of rock slope protection on bank of the Petaluma River and
installation of a temporary cofferdam in the Petaluma River and temporary erosion
control.
The above projects were approved for Federal Emergency Management Agency (FEMA)
funding to mitigate flood damage.
DISCUSSION
The final construction contract cost is $433,910, which includes all bid item work and there are
no change orders for this project. All improvements were in place prior to the recent rains and
functioned as intended. There are no disputed claims and the project was completed without any
other significant incidents.
FINANCIAL IMPACTS
It is anticipated that the work for the Various Locations Rock Slope Protection Project will be
reimbursed fully by FEMA through Cal/Office of Emergency Services for actual costs of design,
construction management/inspection, and construction. The following table is a breakdown of
estimated total project cost for Various Locations Rock Slope Protection Project:
Phase

$43,000.00
Contingency
$50,000.00
TOTAL:
$866,231.73
$854,742.18
*This cost includes total amount spent to date for all four locations and for these phases. These
projects have gone through multiple scope changes, time extensions, and staff changes since
2006, which is why the costs prior to construction are more than would typically be seen based
on the construction value.
After retention release, staff will seek reimbursement and project closeout with FEMA.
Following the acceptance of the project, the City Clerk will file a Notice of Completion with the
Sonoma County Recorder and the Finance Department will release the contract retention account to
the contractor within 60 days.
