4. Risk MAP, the NFIP, Hazard Mitigation Planning, and Building Sciences

5. Purpose of the national flood insurance program
Reduce Economic Loss Caused by Flood Events
Losses total nearly $8 Billion per year
85% of declarations
Average of 82 fatalities per year
The NFIP was created by Congress in 1968.
Congress created NFIP:
Create a flood insurance program to enable property owners to protect themselves from financial losses as the result of flood events (private insurance companies were unable to meet the need)
Reduce future flood damage through good floodplain management at the local level
Its goal was to reduce losses caused by floods.
This was to be accomplished by:
Mapping floodplains
Setting minimum floodplain construction standards
Providing flood insurance (since the private sector would not take the risk)
Mandating flood insurance through lending institutions backed by the Federal government

6. Mapping – Flood Studies Regulations Insurance
HOW THE NFIP WORKS
The NFIP is broken out into three disciplines
Mapping – Flood Studies
Regulations
Insurance

7. Purpose of the national flood insurance program
Reduce Economic Loss Caused by Flood Events
Maps the flood risk and assigns insurance rates (FIRMs)
Makes flood insurance available
Sets minimum floodplain construction standards
May reduce the dependency on structural flood control
Promotes floodplain management practices increasing resilience

15. NEXT MILESTONES* DECEMBER 13, 2016 COORDINATION MEETING
PUBLIC MEETINGS
Usually 2/3 months after issuance of preliminary maps
January/FEBRUARY 2017
90-day appeal period
Starts shortly after the public meeting
March/april 2017
resilience
Multi-hazard risk assessments and Development of mitigation objectives
TBD
Fema issues letter of final determination
3-6 months following the end of the appeal period. Dependent on comments and appeals received.
Summer 2017
Effective date
6 months after lfd
winter 2017/2018
*Subject to coordination and funding

16. APPEALS
All appeals must be supported by scientific and technical data.
Alternative methods or applications result in more correct estimates of base flood elevations.
Criteria documentation available:
Establishes areas eligible for appeal
Identifies documentation needed to support an appeal of each flood hazard type (e.g. modeling, topography)
Reiterates:
Certification requirements
The importance of submitting analyses in the same vertical datum and tying into to the effective model and mapping

17. Expanded Appeals Process:
TERMINOLOGY
Expanded Appeals Process:
Appeal: a formal objection to the addition/modification of preliminary BFEs/flood depths, SFHA boundaries or zone designations, or regulatory floodway boundaries, subject to the due process requirements outlined in Part 67 of the NFIP regulations
Comment: an objection to a base map feature change or any other non-appealable change

18. Signed letter with backup technical information (mail to):
APPEALS & COMMENTS

19. LETTERS OF MAP CHANGE (LOMC)
Applicable at any time
LOMA: For property owners who believe a property was incorrectly included in a SFHA. An elevation certificate supports a LOMA, but by itself, does not remove the insurance requirement.
LOMR: Removes land that has been graded or filled (physical changes) since the date of the map. A LOMR can waive flood insurance requirements.
LOMC Hotline: FEMA-MAP

20. FUTURE STEPS AFTER APPEAL PERIOD
FEMA addresses submitted comments and resolves any appeals.
FEMA issues the Letter of Final Determination (LFD).
Officially notifies community of final base flood elevations.
Indicates effective date of FIRMs as 6 months from the date of the letter.
Local jurisdictions adopt an amended ordinance that is compliant with your map and FEMA standards.
Local jurisdictions develop and implement additional outreach strategies as desired.

21. Flood Damage Prevention Ordinance
To participate in the NFIP, communities must adopt, implement, & enforce a Flood Damage Prevention Ordinance (FDPO) that meets or exceeds the minimum NFIP standards. As a reminder, Flood Ordinances must be updated, adopted and in effect when the new maps/study become Effective (6 months after the LFD).
DLCD will work with your community on updating and adopting a new Flood Ordinance. Contact David Lentzner for assistance (503) ,
