SUBJECT: UPDATE ON THE WALNUT CREEK/GRAYSON CREEK LEVEE
REHABILITATION PROJECT
District Project (DP) 7341 will raise the Walnut and Grayson Creek levees along the
District's plant to ensure protection against a 0.2% chance ("500- year") storm event with
freeboard. The Fiscal Year (FY) 2015 -16 Capital Improvement Budget anticipated
$200,000 of expenditures in FY 2016 -17, with a total budget of $600,000. This is a joint
project between the District and Contra Costa County Flood Control District (FCD) and
as proposed will be a 50 -50 split for all project costs. An agreement between the two
agencies will need to be taken to the respective Boards.
The FCD has been taken the lead for -the project and developed a preliminary cost
estimate of $2.2 million. A sample Expenditure Summary statement with the preliminary
estimate is attached. The District anticipates accepting and storing suitable soil on the
Kiewit buffer property to provide in -kind contributions to reduce the costs for the project.
Additionally staff anticipates utilizing in -house survey to research boundaries and write
descriptions for real property agreements with FCD that will be necessary for the
project. Both parties will provide an accounting of expenditures quarterly for
reconciliation. In order to track time spent on these efforts and utilize all District costs in
the reconciliation, staff recommends advancing the project to this fiscal year. Therefore,
staff requests allocation of $200,000 from Treatment Plant Program contingency funds
to open DP 7341.
