NFIP Overview U.S. Congress established the Nation Flood Insurance Program (NFIP) with
the passage of the National Flood Insurance Act of 1968
Federal Program enabling property owners in participating communities to
purchase insurance
Participation in NFIP is based on an agreement between communities and
the Federal Government
Community must adopt and enforce a floodplain management ordinance to
reduce future flood risk to new construction in floodplains
Provides an alternative to disaster assistance
Three aspects of the NFIP
Floodplain Identification and mapping
Floodplain Management
Flood Insurance

FEMA Mapping Goals Risk Mapping, Assessment and Planning
Identify Flood Hazards
Reduce loss of life and property
through effective local mitigation
activities
Provide digital flood hazard data in
accessible formats

FEMA Mapping Goals, cont…
Address gaps in flood hazard data
Increase public awareness and understanding of risk
Assist and support local entities engaging in risk-
based mitigation planning
Provide digital data

FEMA Mapping Study Priorities
FY09
Expiring PALs and other levee issues
Coastal studies
Other engineering needs (such as datum conversions)
FY10 +
Coastal studies
Watershed-based hazard identification

COMMUNITY AGREEMENT Acts as an acknowledgement of the Flood Study Project
and an agreement to work together toward a common goal
Documents good faith efforts to collaboratively assess the community’s need
Develop an appropriate Scope of Project
Develop and Publicize the updated map that results from the Flood Map Project
Lake County has entered into a Cooperating Technical Partner (CTP) agreement with FEMA RIX

LEVEES: PROTECTION WITH RISK
Levees are designed to provide specific level of protection They can be overtopped or fail in larger flood
events They require regular maintenance and
periodic upgrades to retain their level of protection
FEMA urges people to understand their flooding risk involving levees
![Page 16: In coordination with FEMA Scoping Meeting Lake County, California February 19, 2010](https://reader030.vdocuments.site/reader030/viewer/2022032703/56649d0f5503460f949e4d99/html5/thumbnails/16.jpg)
LEVEE OWNERSHIP
FEMA does not own, operate, maintain or certify any levees
FEMA can accredit a levee certification provided by others
The levee owner can certify the design, construction, operation and maintenance of a levee
Community is benefiting from the levee
![Page 17: In coordination with FEMA Scoping Meeting Lake County, California February 19, 2010](https://reader030.vdocuments.site/reader030/viewer/2022032703/56649d0f5503460f949e4d99/html5/thumbnails/17.jpg)
FEMA ACCREDITATION AND CERTIFICATION
If adequate certification is provided and accepted, FEMA will accredit the levee as providing protection
If levee is certifiable, but community needs time to gather documentation required in CFR65.10, a Provisional Accreditation status is available through the Provisionally Accredited Levee (PAL) process.
If levee certification is not attainable, the area will be mapped with the levee not providing protection per direction in PM52
