How/When Does Alternatives Analysis Happen?
Formal project planning – USACE projects good exampleFEMA mitigation project developmentPlanning – Mitigation, Comprehensive, Capital
Improvements, Post-Disaster RedevelopmentPublic meetings / hearings
Regulatory changes, project hearingsAfter an “event”
Disaster Court Case
When else?

What are the Flood Mitigation Options?
Prevention – Keep hazard risk from getting worseProperty Protection – Modify existing development
subject to hazard riskPublic Education & Awareness – Inform people about
hazardous areas and mitigation actionsNatural Resource Protection – Reduce effects of hazards
& improve quality of environmentCritical Facility Protection / Emergency Services – Actions
taken to ensure continuity of emergency servicesStructural Projects – Large manmade structures to
protect people and property at risk

Value of Ecosystem Services
Recent economic studies are attempting to better characterize and value a
variety of (generally) non-market values of
floodplains and watersheds

Climate Change / Adaptation
The National Climate Assessment (NCA) evaluates the effects of climate change in the U.S. The NCA builds on an extensive scientific literature and series of recent assessments of the historical and potential impacts of climate change and variability
Last one completed in 2009, next version scheduled to be completed in 2013
Fundamental shift in focus at least for some sectors – focus on data/tools for the practitioner community
Water resources sector as well as specialty and regional sectors

Long Term Maintenance / Financing?
Need to look at both macro and micro scale Watershed wide flood control service Small detention/retention basins in neighborhoods, new subdivisions
Three drivers of change of funding from a federal perspective: Massive amounts of infrastructure needing repaired/replaced, federal debt, and no earmarks
Must better align incentives/disincentives for owners to maintain
How do we serve a more self financed world? Develop sustainable funding sources – PPPs? Technical assistance

Observations and Conclusions
Complex flood problem = multiple mitigation solutionsNeed good data that supports alternatives analysis
Are we spending mitigation planning wisely in this regard? Is the risk assessment data supporting mitigation alternatives analysis
RiskMAP is going to drive a mitigation discussion across the nation – are we, as professionals, ready to deliver?
Alternatives analyses occurs formally and informallyWe need to do a better job as professionals assisting
communities and states in looking comprehensively at mitigation alternatives
