6
6 Purpose of This Meeting Prepare for potential flood map production in coming Fiscal Years –Identify community map update needs –Identify community data useful in map update process –Determine any ongoing projects that may affect project timing To adjust priorities if major factors come to light Nolton
7
7 National Flood Map Modernization Nationwide, 5-year, $1 billion program Update FEMA’s Flood Insurance Rate Maps (FIRMs) for the entire nation Produce seamless flood data Build State partner mapping capacity Produce quality maps Reduce map production time Reduce cost/time for future updates
8
8 Map Mod Benefits to Community Digital Flood Insurance Rate Map (DFIRM) –GIS information –Includes database Improved tool for floodplain management Better flood insurance coverage and rating Countywide DFIRMS—easier to use Community input into process Leverage previous community investments Maximize state/federal/local resources
9
9 Georgia Map Mod Mapping State End-to-end production Aggressive outreach program Must map all 159 counties in State by end of FY09 Budgets very tight Many unmapped communities in Georgia require creation of first time flood map FEMA will not pay for topographic data acquisition
10
10 Georgia Flood Mapping Plan Create new flood maps for entire state over five years First-cut factors for draft priority –Population density –Recent disaster history –Age of maps Plan county-based for FY03-FY06 Plan is RDC-based for FY07-FY09
11
11 Georgia Plan Anticipated DFIRM Delivery Year
12
12 Key Elements of GA MapMod Project web site –www.GeorgiaDFIRM.com –Project status –PDFs of maps –Memorandums of Agreement –Submit Map update need –Join email list –Handouts and informational documents on technical and administrative topics
13
13 Website—County Status
14
14 Memorandum of Agreement “Important Features” Section
15
15 FEMA Role in Map Mod FEMA –Sets national standards and requirements Guidelines and Specifications –Provides significant share of funding –Agreements with States and Regional Authorities as Cooperating Technical Partners (CTPs) –Is an advocate for Georgia on National level –Established National Metrics Beth
16
16 NSP Role in Map Mod National Service Provider (NSP) –Supports FEMA in the implementation of Map Mod Program Manages the overall Map Mod program Provides tools and procedures Development of web-based data management system: Multihazard Information Platform (MIP) –DFIRM and supporting data storehouse –Deliverables by phase –www.hazards.fema.gov/www.hazards.fema.gov/ Beth
17
17 State Role in Map Mod Department of Natural Resources (Environmental Protection Division) –Manages flood mapping program –Prioritizes mapping projects on State level –Links local priorities to National priorities –Provides services, staff, and funding to support Map Modernization program
18
18 RDC Role in Map Mod RDCs –Use GIS data developed by State in their programs –Provide information on flood mapping needs –Provide data (where available) to update maps –Offer complementary programs to work with communities –Assist in outreach and communication
19
19 Community Role in Map Mod Community: –Help set local flood mapping priorities –Drafting, implementing, and enforcing floodplain management measures –Use most recent FIRMs –Provide information to State & FEMA to help keep FIRMs current –Meet minimum standards of the NFIP to continue eligibility for NFIP flood insurance –Give consideration to higher standards for floodplain management (State model ordinance)
20
20 Other Roles in Map Mod PBS&J –Contractor for State –Incorporates community data into flood maps –Completes flood map updates via engineering and GIS development –Directly coordinates with communities Other Federal and State Agencies –Provide information on flood mapping needs –Provide data (where available) to update maps –Offer complementary programs to work with communities Collis
21
21 Time frames given are approximate and will vary from study to study Flood Mapping Process
22
22 A DFIRM is… Digital Flood Insurance Rate Map A GIS map of the floodplain limits, other flood features and base map data A database of flood-related information Mike
23
23
24
24 GA MapMod & New H&H State operating plan is –Incorporate community data onto DFIRMs wherever possible “Incorporate Studies By Others” –Where Georgia undertakes H&H, do so in a way that facilitates use of models for other purposes
25
25 Georgia Map Mod Produces Digital H&H models in SELECT areas –Where “Studies by others” incorporated –New limited detail study –These two elements account for about 8% of study budget in most counties Use of effective FEMA information in many other areas –Approximate (Zone A) study –Detailed (Zone AE) study
26
26 Incorporate Studies By Others Take community-supplied data and incorporate into DFIRM –Data must represent EXISTING or FUTURE 100- yr flood boundaries –Submitted data is reviewed Verify it meets FEMA specifications –H&H –Mapping –Topographic base –Consistency If changes needed, sent back to originating engineer –Data archived with final study
27
27 Incorporate Studies By Others Example: Gwinnett County –County has already completed 100-yr existing and future conditions mapping countywide –Georgia Map Mod showing 100-yr existing and future conditions floodplain on DFIRMs
28
28 Incorporate Studies By Others NOTE: FINAL GWINNETT MAP WILL BE VECTOR-BASED, NOT ORTHO- BASED AS SHOWN HERE
29
29 Limited Detail Study Georgia Limited Detail standards –Uses community 2-4’ equivalent topography –Bridges & culverts measured (not surveyed) GPS location of bridges –Regression or HEC-HMS hydrology GIS watershed boundaries, TOC, etc Easy to change for other flows –HEC-RAS model GIS XS, centerline, FP boundary –All GIS and H&H data given to community –State standard for display of limited detail
30
30 Limited Detail Study
31
31 Use of FEMA Effective Information Register existing FIRMs to basemap; if available existing workmap is used instead of FIRM Existing floodplain boundary lifted from existing map Clean up spots where the paper map obviously does not match the base map and other simple fixes

36 QUESTIONS SO FAR ? Mike
37
Breakout session to review map update needs Mike
38
38 What we need from you Data from your community / organization –Any new or existing flood studies –Recent topographic data or survey –Flood reduction project information –Identification of areas That flood but are not on current FIRM’s as flood zones That do not flood but are on current FIRM’s as flood zones –High water marks (if any) you may have Mike
39
39 What we need from you Mark up scoping map / FIRM panels –Identify needs and provide rationale for each reach proposed for study –Discuss your community’s priorities –Communicate with other communities on cross-boundary priorities –Identify points of contact for participants Mike
