YUBA RIVER BASIN PROJECTSchedule and Cost Change Request(SACCR)CVFPB Agenda Item 10

April 17, 2009


Overview

Overview

  • Yuba County Water Agency: Local sponsor

  • Goal: Provide at least 300-year protection to the City of Marysville and 200-year protection to

    RD 784.

  • Maximize federal funds by:

    • Completing GRR

    • Secure credit from state & local expenditures as

      part of the TRLIA levee improvements

    • Defer non-Federal costs on Marysville

      until Congress Authorizes the GRR

1


Project elements

Project Elements

  • General Reevaluation Report (GRR) - RD 784

  • Marysville Ring levee

2


Grr scope

GRR Scope

  • Evaluate the Federal interest in reducing the risk of flooding in RD 784

  • Alternatives to include the TRLIA Program, and additional alternatives that provide greater and lesser levels of protection for the area

  • GRR will establish the eligible credit from the TRLIA work that can be used towards Marysville or additional improvements in RD 784

3


Why the grr scope increased

Why the GRR Scope Increased

  • We Learned a lot from the 1997 Flood Event

  • 1998 FS did not identify a need for work on the Lower Feather, Bear & WPIC Levees for 200-year protection

  • After the 1997 Flood Event

    • New underseepage guidelines required more work to achieve a given level of protection

    • Revisions to hydrology

  • The DWR Floodplain Mapping Study (Early 2000s)

    • Identified FEMA deficiencies in RD 784

    • Lower RD 784 freeboard deficiency

    • Yuba River left bank stability problem

    • Sunk Costs > $8M

    • Additional Design Fees, Field Work, and Modeling

    • Additional Evaluation of Ecosystem Restoration, Environmental Data and In-House Labor

      Details Included in Board Package

Marysville ring levee

Marysville Ring Levee

  • Strengthen 7.5 miles of levees

  • $50M estimate

    • 65% Federal: $32M

    • 35% Non-Federal: $18M

    • State: $12.6M

    • Local Share: $5.4M

  • 2008 Corps approval of Ring Levee as a “Separable Element”

    (OK to Begin construction while GRR is underway)

  • 7


    Marysville strategy

    Marysville Strategy

    • Begin construction – no delay or risk from the GRR (separable element)

    • Secure adequate appropriations

    • Minimize State/local cost-share:

      1. Section 103(l) cost-share deferral, Corps Approval on April 3, 2009

      (There is still a Non-Federal 5% cash requirement)

      2. Secure credits from TRLIA

      and RD 784 for the local cost-share
