Congress Set the Policy

  • Flood Control Act of 1928- Lower Mississippi Valley
  • Flood Control Act of 1936 - The Nation
    • …destructive floods upon the rivers...constitute a menace to national welfare; it is the sense of Congress that flood control is a proper activity of the Federal Government
    • … the Federal Government should improve or participate in improvements,,,for flood control purposes if the benefits to whomsover they accrue are in excess of the estimated costs...

But Flood Damages Continue to Grow -

And Many Blame the Engineering

Upland and Floodplain Development Has Substantially Altered the Natural Environment

telling it like it is
Telling It Like It Is
  • UNP Assessment
  • Sharing the Challenge
  • USACE Flood Assessment
  • California Governor’s Task Force
  • Western Water Policy
  • Higher Ground
  • Living with the Red
  • What Happened?
  • How Prevent Similar Floods?

Big Floods
  • Major Floods Have Been Significant Hydrometeorologic Events
slide17

People and Property Are at Risk in the Floodplain

  • Most Floodplain Residents Don’t Understand the Risk
    • 14% of Non-Federal Land in Contiguous 48 States is in 100 Yr. Floodplain
    • >17,000 Communities Have Floodprone Areas
    • Flash Floods Occur in All 50 States
  • Many Structures Unnecessarily Located in Floodplain
slide18
….and It Isn’t Going to Get Any Better
    • Increased Development/Growth
    • Climate Change/Climate Variability
    • Uncertainty
the goals
The Goals
  • Reduce Flood Damages
  • Protect and Enhance the Natural Environment
  • Continue Growth

Sustainable Development

what needs to be done
WHAT NEEDS TO BE DONE
  • Share Responsibility and Costs for Floodplain Management Among Federal, State, and Local Governments and Impacted Populace
slide23
Minimize Damages to Development that Does Occur and Has Occurred
    • Hold the Water Where It Falls
slide25

Minimize Damages to Development that Does Occur and Has Occurred

    • Relocate Endangered Structures
    • Acquire Marginal Lands
slide26

Minimize Damages to Development that Does Occur and Has Occurred

    • Use Levees/Floodwalls, When Justified
slide27
Mitigate Damages that Will Occur
    • Establish Early Warning Systems
    • Insure Those at Risk
    • Educate Present and Potential Floodplain Occupants
slide28
Deal with the River Basin as an Ecosystem
  • Concurrently Restore, Maintain and Enhance the Natural Environment

Challenges

Addressing Policies that:

  • Promote intensification in risk areas
  • Ignore changing conditions
  • Ignore adverse impacts to existing properties
  • Undervalue natural floodplain functions

Water Resources Professionals Must Continue to be Involved
  • Educationally
  • Technically
  • Politically/Institutionally
