Mission: Mitigate the losses, costs, and human suffering caused by flooding.

and

Protect the natural and beneficial functions of floodplains.

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

Categories of Ecosystem Services

Ecosystem Services: High and Low Dollar per Acre Estimates

Final Annual Value of all Ecosystem Services Provided by the Puyallup River Watershed

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
