Moving Forward

Texas Floodplain Management Association Conference

Larry Voice, FEMA Region 6

Texas Coastal Mapping Effort

• 367 miles of open Gulf of Mexico shoreline
• 22 major hurricanes since 1875
• Current maps dates range from 1971- 2007
• Update includes a comprehensive storm

surge model for the Texas Gulf Coast

• Half of the 17 counties are rural and

sparsely populated

Project Update – Storm Surge Study

• USACE completed storm surge study for entire coast
• Validated against historic storms (Brett, Allen, Rita, Carla, Ike)
• Provides Stillwater Elevations

Surge elevations for Hurricane Alicia, modeled as part of the Texas coast storm surge model

• validation. The color scale
• n the right is an indicator
• f storm surge depth with

the lowest values indicated in blue.

Project Update – Wave Analysis

• Nearly Complete
• Preliminary maps submitted starting in April
• Issue Preliminary FIRMs starting in June.

Engagement Opportunities

 To Date

 Project Scope and Analysis Meetings  Meet and Greet Meetings in 2007  Elevation Grid Review Meetings  WHAFIS Set Up Meeting  Technical Workshops  Flood Risk Review Meetings

Collaboration Throughout

• Mapping project partners include:
• FEMA – Region 6 and Headquarters
• U.S. Army Corps of Engineers
• Texas Water Development Board and TNRIS
• FEMA’s Mapping Contractors
• 17 county governments and their communities
• The Whole Community concepts benefit:
• Residents and Business owners

Texas Coastal Hazard Analysis Resources & Technology  TXCHART

• Concerted effort to broaden the education and information

sharing throughout the Floodplain Mapping Process

• Effort aims to increase awareness of coastal flood risks of

residents, community officials and business owners

• Interaction of local community officials and FEMA in the review of

intermediate data, allowing local input to be gathered and included as the modeling is being finalized

• Preparation of non-regulatory Flood Risk Products to discuss

flood hazards and understand the variability of study results along the coastline

• Promotion of pro-active mitigation strategies for coastal

communities once new data is provided.

Project Timeline

Communities should plan community outreach now

New Flood Maps and risk products Better Informed Coastal Communities

=

Community Role in Public Education & Outreach

• Risk Awareness begins at the Local Level
• Easily make information available
• You are the trusted source
• Inform your citizens
• Tools and templates available
• Review your current Community Outreach Plan
• Contact us – we have products to support your

efforts

• Community Consultation Officers (CCO)

Meeting

 FEMA will review Preliminary FIRM and FIS with

community

 Explanation of scientific methods for determining flood

risk data

 Explain the regulatory process for map adoption  Discuss FIRM and FIS report maintenance through LOMRs  Impacts of New Mapping on Insurance  Introduction to Non-Regulatory Flood Risk Products  Introduce and coordinate upcoming Meetings – led by

community , supported by FEMA

Upcoming Engagement with Study Results

Upcoming Engagement with Study Results - New

• Resilience Meetings
• How to use the Non-Regulatory products?
• Local officials, planners, emergency managers, regional

authorities

• Stakeholder Mapping Update meetings
• How will map changes affect your citizens?
• Local realtors and insurance professionals
• Open Houses (Community to lead/FEMA support)
• How the maps will affect your property?
• Public – residents and business owners
• Prepare now for new Risk Information

Awareness Prompts Action

Limit of Moderate Wave Action (LiMWA)

 FEMA does not impose floodplain

management requirements based on the LiMWA.

 The LiMWA is provided to communicate

the higher risk that exists in the area.

 1.5-foot breaking wave in the LiMWA

zone can potentially cause foundation failure

 Communities are encouraged to adopt

building construction standards similar to Zone VE in those areas.

Limit of Moderate Wave Action (LiMWA)

 LiMWA is Non-Regulatory  Defines the Coastal A Zone

Limit of Moderate Wave Action (LiMWA)

Landward limit of 1.5 ft breaking wave height

Why Show the LiMWA?

 Over the years, post-storm damage assessments by

FEMA Mitigation Assessment Teams (MATs) show that A Zone buildings constructed directly behind V Zones

• ften suffer damage due to surge, breaking waves,

coastal erosion and scour

Taking Action to Reduce Risk

Community Awareness and Action = Reducing Flood Risk Long-Term

Share this information with your Community



Use the new products to enhance Hazard Mitigation Plans Four basic types of mitigation objectives:

• Prevention
• Property protection
• Flood control
• Emergency services

Additional mitigation objectives:

• Public education and awareness
• Natural resources protection
• Sustainability

Recommended Practices in Coastal A

Goal - To build local capacity for implementing priority mitigation

activities along the Texas coast.

Objectives – to help communities:

• Better understand their flood risk
• Identify strategies they can use to reduce that risk and improve

their resilience to floods

• Identify resources available to help them implement those

strategies

• Understand the importance of communicating flood risk to their

residents

• Know their role in helping their communities take action to

reduce their flood risk

• Use the new Flood Risk Data available

Resilience Meeting

Goals

• Initiate effective partnerships and promote involvement with

insurance agents, realty professionals and lenders

• Convey technical information and educate stakeholders to use new

tools and flood risk data

• Build stakeholder awareness of coastal flood studies, the post-

preliminary mapping process, NFIP policy and the impacts on affected citizens

One Meeting per County

• Coordinated with the county – Communities encourage participation
• f their stakeholders

Includes: Background on the project, Insurance Q & A, demo of

mapping portal and website



Stakeholder Mapping Update Meeting

Public Open House

Goals

• Promote public awareness of the flood risk
• Convey technical information and educate public

to use new tools to make informed decisions about their flood risk

The Open House meeting:

• Led by County and Community FPAs
• FEMA supports your Outreach
• One per county – get the word out to your

citizens!

• Interactive Digital Maps, Community tables with

paper maps, Engineering support, Insurance Specialists, new flood risk products, coastal mapping video, TXCHART.com assistance

• Levees must be certified to 44 CFR 65.10
• If levee is not certified, FEMA de-accredits the levee
• FEMA is currently in the process of evaluating options to

replace their de-accredited levee approach with a suite of methodologies that are

• technically sound, credible, and cost effective
• Project Implication – delay in map delivery
• Counties with de-accredited levees will not proceed with official

Preliminary FIRMs and Post-Preliminary Process without new procedures

http://www.fema.gov/plan/prevent/fhm/lv_lamp.shtm

Challenges - Levees

Next Steps

• Preliminary Maps issued
• Community Consultation Officer
• Resilience meetings and Stakeholder meetings
• Open Houses scheduled – coordinated with counties
• 90-day Appeal Period begins
• Letter of Final Determination
• 6-month compliance period
• Effective Maps issued

Get the word out to your residents…

• Coastal Texans must be informed; it’s up to everyone to

know their risk, know their role, and take action now.

• Through flood studies and updated maps, communities

in coastal areas will receive more precise flood risk information about the flood risk where they work and live.
