Flood Hazard Reduction Program

Reducing Future Flood Damages

The goals of the program are to:

    • Implement projects that reduce future flood damages.
    • Minimize expenditures to repair damaged areas.
    • Characterize flood problems.
    • Evaluate alternatives to solve problems.

         Examples of flood hazard reduction projects are:

    • Construction of setback levees and overflow spillways.
    • Designation of overflow corridors in over-bank areas.
    • Acquisition of properties with repetitive flooding.

Two alluvial fan studies have been completed for Jones Creek (PDF) and Canyon Creek.  
Acquisition Projects
The development of flood hazard reduction projects ensures:

  • Problems are not transferred to another location within the basin. 
  • Project implementation will result in long-term reduction in flood damages.
  • Reduction in public expenditures throughout the basin.

Project Implementation

The process includes detailed analysis and design, permitting, and construction. Flood hazard reduction projects can be either structural or nonstructural in nature.

  • Structural measures include setback levees, overflow spillways, and overflow corridors in over-bank areas.
  • Non-structural projects include acquisition, relocation, and elevation of flood-prone structures.
