$2,700 billion
In damages (in 2010 dollars) across Texas, Louisiana, Mississippi, and Alabama.

Federal Investment needs to be PROACTIVE
NIBS Multihazard Mitigation Council report to Congress on behalf of FEMA (2005):
• Money spent on reducing the risk of natural hazards is a sound investment.
• On average, every $1 spent by FEMA on hazard mitigation…provides the nation about $4 in future benefits.

What Does NOT Work?
1. First thing you do in a disaster is throw out the rules2. First thing you do in recovery is throw out the rules
Executive Order 136043. Current project development and implementation process is incapable to addressing
coastal and water resources crisis facing America4. You cannot perfect solutions before acting – dynamic environments – better science5. Waiting to invest until AFTER disaster strikes/under-funding6. Devising “solutions” to single problem in a vacuum (levees v. ecosystem)7. Divided mission (EPA, NOAA, USACE, FEMA, USFWS, NRCS, CEQ, OMB…..) means no
one is accountable8. States, local governments and stakeholders on the sidelines (i.e. zoning)9. Segregating similar programs by agency (stove-piping)10. Missing schedules and budgets – uncertainty kills

What Works?
1. Functional organizational structureFormation of the Coastal Protection and Restoration Authority BoardCoastal board of directorsIntegrating/co-mingling funds
2. Schedule public meetings to deliberate and provide public inputDiscuss policy options/trade-offsAccountability venue
3. Establish prioritization metrics that reflect regional/state/local values4. Provide clear, transparent, accountable project process processes5. Develop annual report card to show successes and learning opportunities6. Move forward with 70+% solutions and use robust adaptive management 7. Communicate honestly – can’t promise “a chicken every pot”
Residual risk exists8. Proactive versus reactive actions9. Identify “double” and “triple” wins (multi-service objectives)10.Delivering what you promised
