REASONS FOR RECOMMENDATi.ONS AND BACKGROUND:
A. On April 10, 2007, the Board of Supervisors declared an emergency and authorized the Chief Engineer to
proceed in the most expeditious manner to repair or replace the Lower Walnut Creek flood control facility as
directed by the US Army Corps of Engineers.
B. Repair status:
The Contra Costa County Flood Control and Water Conservation District(District)prepared the Lower Walnut
Creek Corrective ActionPlan and presented it to the US Army Corps of Engineers for consideration on June 1 1.,
2007. A status report, including this Corrective Action Plan (CAP),was presented to the Transportation,Water
and Infrastructure Committee on .lune 25, 2007. Project plans were prepared and the District contracted with
Pacific States Environmental Consultants to construct the first phase of the Lower Walnut Creek Interim
Protection Measures project pursuant to the CAP. This first phase of the project was completed in early
December 2007. However, additional work is required to fully implement the CAP.
The CAP is currently under-review by US Army Corps of Engineers Headquarters. The full scope and schedule
of the CAP will not be known until completion of the federal review.
CONSEQUENCES OF NEGATIVE ACTION:
No11co11Cu1'1'ence with the above recommendation may signilica.ntly delay implementation of the remaining CAP
work in Lower Walnut Creek flood control facility and prevent the District from meeting the correction schedule
required by the US Army Corps of Engineers.
