Meeting Objectives To review and discuss the mapping project data

development methods

To review and discuss the Risk MAP non-regulatory products and datasets

To discuss how the products can be used to help make decisions to reduce flood risk

To discuss benefits of and resources for local communication about risk to residents

Answer questions

Risk MAP Project StatusWhere have we been? Discovery Risk MAP mapping project

• Study area A• Study area B• Study area C• Digital conversion

Other issues that need to be discussed proactively

Where are we going? Flood Risk Review (TODAY) - Risk MAP risk assessment, communications Resilience Meeting - Risk MAP mitigation strategies, communications Final Meeting – mapping project results, review, discussion Public Meeting – local communication of mapping results, risk, mitigation

May have to update datasets to include whatever we are

providing

5

Flood Risk Database Primary storage device for flood

risk data Stores data to create:

• Flood Risk Report• Flood Risk Map

Delivered digitally Includes non-regulatory data for

local use

Data Delivered

6

Flood Risk Report Increases general flood risk awareness

• Risk definitions and causes• Risk reduction techniques and mitigation practices

Delivers community and project level results• Project results summarized by:

− Communities− County, Watershed, or Project Area

Provides information to enhance other efforts• Local hazard mitigation planning• Local emergency management planning• Local master planning and building development

7

Flood Risk Map Promotes risk awareness

• Contains results of Risk MAP project non-regulatory datasets

• Promotes additional flood risk data not shown but located within the Flood Risk Database

10

Flood Depth Grids Show flood inundation as a function of an event’s

magnitude or severity Show that flood risk varies within the floodplain Demonstrate the risks associated with different flood

depths, probabilities, and velocity Serve as key inputs to HAZUS Risk Assessment

Analyses Serve as pre-screening criteria for mitigation project

potential (e.g., BCA > 1.0 with positive 10-yr depths)

Flood Risk Assessment Quantifies flood risk in dollars:

• Potential damage severity for different flood frequencies • Identify locations with possible cost effective mitigation options

Identifies areas of relative flood risk:• Floodprone areas• Vulnerable people and property

Helps estimate potential losses due to flood risk:• Losses from Average Annualized Loss (AAL) Study • Refined losses from new flood study depth grids

Areas of Mitigation Interest Identifies areas that may be affecting flood risk that

would benefit from raised local awareness Raises awareness of local stakeholders within and

upstream of the watershed that may be contributing to flood risk and associated interrelationships

Provides input to local mitigation plans

Communicating about Flood Risk Citizens expect to hear about flood risk from their

local officials more than any other source By sharing flood risk information with them, they can:

• Take action to protect themselves, their families, and businesses • Improve your community’s resilience to flooding• Support implementation of your mitigation plan

Review the “Communications Guide” for ideas of how to use these products to communicate risk

Use risk data to identify areas for outreach

22

Risk MAP Tools Help Communicate Risk

Community Awareness

AOMI

RiskDepth Grids

Citizen engagement, community

commitment, and mitigation action

Update balls to include whatever we are providing

23

Next Steps Review and consider the risk data Consider communication strategies for

educating public about flood risk Inform mitigation planning efforts underway Begin identifying appropriate mitigation actions

Thanks for participating! We’ll be talking again soon.
