and Crediting Tsunami Mitigation

Mike Mahoney, FEMA Mitigation

CRS Quick FactsCRS Quick Facts

What is the CRS? Voluntary incentive program for NFIP participating

communities.

Reduced flood insurance premiums for citizens in return for better floodplain management by communities.

CRS is modeled after the ISO fire insurance rating

system.


CRS Goals

Reduce flood damage to insurable property.

Strengthen/support insurance aspects of NFIP.

Encourage a comprehensive approach to Floodplain Management.

CRS Tsunami CreditsCRS Tsunami Credits

CRS provides credit when local governments:• Map tsunami run-up areas• Acquire tsunami hazard areas for open space uses.• Zone tsunami hazard areas for open space uses. • Adopt land use planning measures that control development and

uses. • Require new structures to be built at or above the tsunami flood

elevation. • Prohibit new critical facilities in tsunami hazard areas and adopt

tsunami construction requirements.• Develop local public information and education programs.• Receive the NOAA TsunamiReady designation.


CRS Element 610 credits a local government that has been designated by the National Weather Service (NWS) as a TsunamiReady community.

For TsunamiReady credit, the community must: • meet the other mapping requirements for special hazards credit, and, • have adopted a tsunami hazard operations plan or annex that addresses

actions to take after a tsunami warning. • Credit Points = 30 points for obtaining and maintaining the designation

as a TsunamiReady community. TsunamiReady communities may also meet CRS communications and

educational requirements, so credit may also be awarded for Flood Threat Recognition (FTR).

• Community documents that it monitors, and is ready to react to reports from the West Coast and Alaska Tsunami Warning Center (WC/ATWC) or the Pacific Tsunami Warning Center (PTWC).

• Credit for FTR = 20 points


410: Mapping of tsunami hazard area • Max 50 pts

420: Open Space Preservation in Hazard Areas• Max 50 pts

430: Regulation of Tsunami Hazard Areas• Max 70 pts. using:• 40 pts for elevation above tsunami heights, • 15 pts for prohibiting critical facilities, • 30 pts for following tsunami criteria in FEMA CCM, • 15 pts for special inspections of tsunami construction, • 15 pts for program to upgrade existing buildings, • 15 pts for prohibit hazardous materials


510: Floodplain Management Planning• Gives credit for including tsunami and other hazards.

520: Acquisition and Relocation• Gives credit for tsunami-related activities if in SFHA.

530: Flood Protection• Gives credit for elevation of buildings above hazard levels,

but cautions to follow seismic and tsunami codes.

CRS Tsunami GuidanceCRS Tsunami Guidance

CRS currently updating a guide for tsunami credits. Expected to be available by next year.

CRS contractor responsible for tsunami credits is Berry Williams, ISO.

CRS Task Force includes Josh Lott, NOAA, Office of Oceans and Coastal Resource Management

I serve as FEMA technical advisor.

Mitigation Planning and FundingMitigation Planning and Funding

State Mitigation Plans required under Disaster Mitigation Act 2000. All Pacific coastal states have developed State Mitigation Plans that

include addressing the tsunami hazard. Several communities within these States have also developed Pre-

Disaster Mitigation (PDM) plans that address the tsunami hazard, making them eligible for funding under PDM grant program.

Many States and communities have recognized their tsunami risk:• Several coastal counties have FEMA approved multi-hazard

mitigation plans that include tsunami chapters. • Some of these Plans include specific tsunami mitigation actions

to protect public and critical facilities. • At least two communities, Seaside and Cannon Beach, OR have

completed planned mitigation activities using local funding.

Tsunami Hazard MitigationTsunami Hazard Mitigation

Tsunami hazard mitigation eligible under the Hazard Mitigation Grant Program (HMGP), which provides mitigation funds for any hazard after a Federally declared disaster.

States allowed to use HMGP funds for any applicable hazard, but project must meet cost benefit rules.

FEMA supported development of a Tsunami Hazard Mitigation Program and mitigation projects in Puerto Rico using HMGP funds following Hurricane Georges.

NEHRP Tsunami ActivitiesNEHRP Tsunami Activities

Tsunami is an earthquake-related hazard covered under the the National Earthquake Hazards Reduction Program (NEHRP).

Improving tsunami hazard awareness, planning, and mitigation is a goal of FEMA and its NEHRP partners.

FEMA funds the public/private consortium Cascadia Region Earthquake Workgroup (CREW), who has developed a subduction zone earthquake and tsunami scenario for planning for affected corporations, lifeline, and government entities.

FEMA is working with the at-risk States to increase public awareness for residents and visitors through NEHRP funding.

FEMA is working on translating tsunami products into non-English languages and to provide more exposure for tsunami preparedness and mitigation products on FEMA’s website.
