Flood Management

Deferred Maintenance Project

The state of California has authorized limited funds to the Department of Water Resources (DWR) to address deferred maintenance of State Plan of Flood Control (SPFC) facilities. Through the Deferred Maintenance Project (DMP), DWR is providing funding to the local maintaining agencies (LMAs) responsible for the maintenance of SPFC facilities to address deferred maintenance of these facilities. Because funding is limited, eligible repairs will be prioritized to maximize flood risk reduction.

Project Objectives

  • Remediate critical deficiencies at DWR’s maintenance yards
  • Evaluate and repair levee penetrations (ex. pipes running through levees)
  • Support LMAs’ work to control and repair rodent damage

Project Implementation

DMP implementation has two phases:

  • Phase 1: LMAs will locate, clean, video inspect, and assess levee penetration conditions. Pipes that need corrective action will be categorized into one of four remedial alternatives: replace, remove, abandon, and slip line.
  • Phase 2: The scope of work includes design, securing environmental and other regulatory permits, and construction of the corrective action. For levees maintained by LMAs, this work will be done by LMAs, under DWR oversight, through a project agreement funded by the DMP. For the State-maintained areas, design, permitting and construction (or construction contracting) will be completed by DWR.
