Scoping MeetingLake County, California February 19, 2010
Agenda • Introductions/Sign-In • National Flood Insurance Program Overview • FEMA Mapping Goals • Community and Partner Agreement Discussion • Scope of Study • Study Process/Timeline • Levees and Other Flood Control Structures • Base Map and Topographic Data • Community Mapping Needs and Requests • 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 AND OTHER FLOOD CONTROL STRUCTURES • Middle Creek • Maintenance: Lake County • USACE-built • Clover Creek • Maintenance: Lake County • USASE-built • Adobe Creek • Maintenance: Lake County • USACE-built
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
BASE MAP AND TOPOGRAPHIC DATA • See Map Provided • Data gathered for this meeting from the following sources: • Midterm Levee Inventory • Tiger Data • Effective DFIRM Data
MAPPING NEEDS & REQUESTS • Previously unstudied areas • Existing studies need to be updated • Topographic changes • Hydrologic changes • Existing or Anticipated Development • FEMA-funded studies prioritized based on: • Community need • Level of risk • Availability of topographic data
ACTION ITEMS • Populate CNMS with Needs and Requests collected during scoping meeting • Acquire Base Map and Topographic products
