Conducting Risk and Vulnerability Assessments

A Critical S tep to Improving Resilience to Flooding Darrin Punchard

15

Is My County Resilient to Flooding?

• Where to begin…

– Talk to local Floodplain Administrator – Review local Hazard Mit igat ion Plan – Review FEMA Flood Insurance S

t udy (FIS ) and Flood Insurance Rat e Map (FIRM)

16

FEMA ’s Risk MAP Program (Mapping, Assessment, & Planning)

The vision for Risk MAP is to deliver quality data that increases public awareness and leads to action that reduces risk to life and property. www.fema.gov/ risk-mapping-assessment-planning

Identifying Risk

“ Floods are act s of God, but flood losses are largely act s of man.”

• Gilbert F

. White

19

Key S teps in Conducting a Risk Assessment

• 1. Assess the Hazard:
• Type – riverine, coastal, flash, urban, etc.
• Location – specific flood hazard areas, including those
• utside of “ mapped” floodplains
• Extent – severity or magnitude, as measured in flood

depth, velocity, speed of onset, etc.

• Frequency - gather information on previous occurrences,

and on the probability of future events*

• Sources and causes – natural versus human-caused

* Consider fut ure condit ions of nat ural and built environment s

20

Key S teps in Conducting a Risk Assessment

• 2. Assess the Problem:
• Identify community “ assets” potentially at risk – people,

buildings, critical facilities, infrastructure, etc., as well as natural features

• Consider relationships and dependencies between

assets, and with what drives t he communit y – social, economic, cultural, and environmental systems

• Analyze risks – identify vulnerable assets, and quantify

exposure using best available data and methods (preferably t hrough GIS )

• Prioritize risks - summarize overall vulnerability and

prioritize specific assets or areas for hazard mitigation strategies, based on potential losses and other impacts

25

Risk Assessment Examples: Assess the Hazard

• Consult with your S

tate NFIP Coordinator and/ or S tate Hazard Mitigation Officer for detailed claims data, including information on “ repetitive loss properties” (bound by Federal Privacy Act rest rict ions)

• Review past damage

assessment reports and online sources, such as NOAA ’s NCDC S t orm Event s Dat abase

• S
• licit input from the public

and targeted stakeholders through various methods as part of planning process

Communicating Hazards

Community Resilience at the American Red Cross

65

Communicating with the Public

• Purpose of communicating is to create ACTION
• Social Science Research:

 Must hear from multiple sources  Must hear same message multiple times  Must hear from trusted source  S

ee peers take the action

 Most motivated to take action on behalf of a

loved one.

66

Community Resilience S trategy (CRS )

Goal: Work with communities to build their capacity to

bounce back from disaster events.

Strategy: Work collaboratively with community leaders and

stakeholders in cross-sector community networks to carry

• ut tailored strategies for risk-reduction and resilience-

building

CRS seeks to build:

• Communit y Preparedness
• Communit y Compet ence
• S
• cial Capit al

67

Community Resilience S trategy in Practice: Coastal Resilience Network

• 2 year proj ect in partnership with NOAA
• Red Cross is working with network of social service

providers to prepare their community through business preparedness, recovery planning and preparedness education

• Participatory assessment conducted
• Creating and pilot testing a Recovery Exercise for

community agencies.

68

Community Assessments

• S

trengthens local awareness of hazards and risks

• Build awareness of local resources and assets which can be

leveraged to address disaster related issues

• Pinpoints gaps in capacity related to disaster preparedness,

response and recovery.

• Encourages collective problem-solving

69

Community Assessments

• Hazard/Vulnerability Assessments

 Encourage communities/ organizations to complete their

• wn assessments
• CERT Teams
• Boy S

cout/ Girl S cout Groups

• Community networks
• Homeschool Groups

 Introduce online tools to businesses, schools, non-

profits

• www.ReadyRating.org (Red Cross emergency planning

template)

• www.S

ervePro.com (Emergency Ready Profile)

• www.Ready.gov/ planning
• NOAA

’s Digital Coast website

70

Delivering Preparedness Messaging

• Meet people where they are

 Partner with community leaders

• Faith based leaders
• Community organizations
• Coaches, Boy/ Girl S

cout leaders, etc.

 Provide messaging in places that are part of daily

routines:

• S

chools/ Daycares

• Places of work
• Dr. Office
• Bank
• Local Media

71

Delivering Preparedness Messaging

• Make it action oriented

 Break message down into small steps and pair with an

action

• When notifying your community about potential flooding,

remind them to make sure they have enough medication for the next 5 days.

• When disseminating flood maps, also remind homeowners

to check into their insurance coverage.

• Ask maj or employers in your area to require employees to

have a family disaster plan on file with HR

72

Developing New Preparedness Messaging

2012 Awareness to Action Workshop hosted by ARC and FEMA

• Recommendations made on:
• Recent research
• Target audience
• Primary message
• Effective channels

New messaging will focus on motivating people to take action

73

S

• cial Media S

trategies

• New “ Digi-Doc” tracks and analyzes social media

data

• Allows Red Cross staff and volunteers to listen and

respond to “ social posts”

• Provides opportunity to

deliver services based

• n real-time

assessment of need

• Empowers clients to

provide information and get help

Recap:

• High level understanding of flood risk assessment, using

available technology and methods that have been used in the past

• Digital Coast tools to visualize inundation including the

Coastal Inundation Toolkit, Coastal County S napshots, S ea Level Rise Viewer and CanVis

• The reason to communicate is to get people to take action.

The way you do that is to talk about what matters to them. Being involved helps to better communicate.
