YUBA RIVER BASIN PROJECTSchedule and Cost Change Request(SACCR)CVFPB Agenda Item 10 April 17, 2009
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 • General Reevaluation Report (GRR) - RD 784 • Marysville Ring levee 2
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 • 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 4
Brief History of the GRR • Reclamation Board Increased the GRR Scope and Cost in 2004 – LRR Increased to a GRR • Corps has Requested Scope and Schedule Revision (2) to cover: • 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 5
GRR Schedule • Alternative Formulation Briefing – July, 2009 • F6 Public Review (Draft EIS) – October, 2009 • Chief of Engineers Report – June, 2010 6
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 • 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 8
Marysville Schedule • Engineering Documentation Report (EDR) - Aug 2009 • Project Partnership Agreement – (PPA) - Nov 2009 • Award First Construction Contract – Apr 2010 9
Requested Action 1.0 Approve Corps SACCR dated March 19, 2009 to increase costs by $10,500,000. 2.0 Amend the LDA with YCWA to increase the total agreement costs. 3.0 Amend the DA with the Corps to increase the total agreement costs. Approval Will: • Allow planning/design efforts to continue on both the GRR and Marysville Levee • Avoid additional schedule delays to the GRR and Marysville construction 10
