Summary of Action Items

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

SCOPE for Lake Co, CA Project

Apply Datum Conversion to effective DFIRM Conversion factor(s) TBD

Address Levee Accreditation through PAL process if applicable

Update base map information Correct mistakes from previous mapping

effort FW not containing stream Incorrect profile for Adobe Creek

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

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

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
