Community Evacuation Planning for Catastrophic Events

Products, Issues, and Lessons Learned from the Hampton Roads Area

Prepared for the

2012 Whole Community

Conference

IL-IN-WI RCPT

Hyatt Lisle, Lisle, IL

Slide2

Presentation Objective

Identify / discuss key community planning issues involved in mass evacuation for catastrophic events and look at specific tasks that the Hampton Roads RCPT undertook to help resolve the issues.Slide3

Community Evacuation Analysis Focal Issues for Catastrophic Events

WHO

needs to / how many will evacuate?WHERE

will evacuees go?WHAT MODES

of transportation are available?

WHAT ROUTES

will evacuees take/does

contraflow

make sense?

HOW LONG

will it take to move the evacuees/what if we don’t have enough time?Slide5

Community Evacuation Analysis Focal Issues for Catastrophic Events

Two Additional Key Issues:

WHAT MESSAGES will we give the community to influence response?

WHAT INTEL will be available to gauge community response and congestion?Slide6

Evacuation Survey:

To capture the knowledge, attitudes & intentions of a random sample of

coastal Virginians in response to a catastrophic event such as a hurricane.

Methodology:

Questions developed and approved

Received GIS map of target regions and surge zones

Purchased random sample of phone numbers located in the area with latitude and longitude included for each

Examined Census block group data for population in each region

Located sample numbers that fit within each target region and zone

Attempted to reach someone at each sample number 10 times

Total sample: 1,725, including 300 cell phone interviews

Completion rates (where a qualified person answered and was asked to participate):

53% for landline phones

34% for cell phones

Special Populations

At-Home Client Zip Code Mapping Purpose to determine with more specificity the scope of the requirement for specialized transportation to evacuate people with access or functional needs who are living at home

Mapping Meals-on-Wheels, Home Delivered Meals, Department of Rehabilitative Services, Dare/Currituck Registry clientsLargest densities of at-home clients were in Hampton, Newport News, Norfolk, Portsmouth, and Suffolk

Special Populations

Medical Care Facilities Surveys

Designed to gauge status of facility evacuation planning at assisted living facilities, nursing homes, and group homesApprox. 1/3 of ALF/NH in VA surveyedMost facilities plan to shelter-in-place (62% of ALF/NH and 69% of group homes)

Concerns: Are in-house transportation resources adequate? Are facilities safe from storm surge that are sheltering-in-place?

Special Populations

Evacuee Calculator Designed to estimate the number of people who will need transportation assistance to evacuate

Focus = 1) those without access to a vehicle or public transportation, and 2) those with a disability without access to a vehicle or public transportation Used census data, updated with American Community Survey resultsInformation displayed via locality spreadsheets, dot-density mapping by surge zone

Total population in the MSA of 45,971 without vehicles

Evacuation Survey Results

Eastern Shore more likely to go to public shelter (18%)

Renters more likely to go to public shelter (18%)

Elderly least likely to stay with friends/family in area; more likely to go to a hotel

Mass Transportation

The Transportation Assets Database Identifies local transportation resources that could potentially be used during a mass evacuation

Total capacity (including vehicles which are wheelchair accessible) = 138,039 Concerns: Will schools really be able to offer over 75% of the total (107,093)?

Are drivers available?
