Background
NOTE - Six storms (Bertha, Fran, Bonnie, Dennis, Floyd & Irene) have impacted or made land fall on the North Carolina coast in the last five years
HURRRICANE DENNISAug 30 - Sept 4
HURRRICAN FLOYDSept 15 - 16
HURRRICANE IRENEOct 16 -17
Why North CarolinaUndertook This Project
State’s vulnerability to hurricanes and flooding 14 federally declared disasters since
1989
Hurricane Floyd damages = $3.5 billion
4,117 uninsured/under-insured homes destroyed as result of Hurricane Floyd
Why North Carolina Undertook This Project
(Continued) Hurricane Floyd revealed flood hazard
data and map limitations Age of State’s FIRMs
55% at least 10 years old 75% at least 5 years old
FEMA’s mapping budget is finite State receives only one updated flood study per
county per year Many counties and communities lack
resources to take on this responsibility Accurate, up-to-date flood hazard data
information crucial to protect lives and property
State Strategies and Implementation
North Carolina’s Strategies
Establishment of Unprecedented Statewide floodplain mapping program
Designated Cooperating Technical State by FEMA
Partnership with (FEMA) and 16 other Federal Agencies
Develop program to collect accurate elevation data and develop flood data to produce FIRMs
Program Deliverables
High-resolution topographic data and accurate DEMs
Engineering basin studies Base map data Countywide digital FIRMs State-of-the-art, dynamic IT
infrastructure Real-time flood forecasting and
inundation mapping capability
Other Program Deliverables
Findings and analysis of LIDAR capabilities Recommend standard for LIDAR accuracy Implementing NSDI approach Tailoring and implementing new FEMA
scoping procedures Testing telescoped post-preliminary
procedures Implementing new DFIRM standard Developing Policy & Procedures Manual Developing Higher Standards Guidebook for
community officials
Direct Benefits from Program
USGS estimates b/c ratio of 3.5:1 Current, accurate data for sound siting and
design decisions Use of updated data for floodplain
management will reduce long-term flood losses Updated data will alert at-risk property owners
of the need for flood insurance Faster, cheaper FIRM updates More equitable flood insurance ratings
through NFIP
Other Benefits of Program
Digital format allows for more efficient, precise flood risk determinations
Digital format will provide more timely updates for floodplain management
Digital format allows for use with GIS for analysis and planning
Digital Information System allows for online access 24 hours a day
DEMs will be useful for almost any engineering or planning applications
Program Approach/ Implementation
Develop Statewide: Basin Plans through scoping process Digital Elevation Models (DEMs) Updated base maps (DOQs or better
local base) Updated flood data Countywide DFIRMs
Digital distribution through State’s IT Hard copy through FEMA’s MSC
State/local relationship for data sharing
Program Approach/ Implementation (Continued)
Phase I—Eastern 6 Basins initiated this year Preliminary FIRMs for White Oak,
Tar-Pamlico, and Lumber by Sept. 2001 Preliminary FIRMs for Neuse, Cape Fear,
and Pasquotank counties by Sept. 2002 Phase II—5 Basins initiated in FY 01-02
Chowan, Roanoke, Yadkin, New, Catawba
Phase III—Final 6 Basins initiated in FY 02-03 Broad, Watauga, French Broad, Little
Tennessee, Savannah, Hiwassee
North Carolina RiverBasins—by Phase
Phase I—bluePhase II—gold
Phase III—green
Program Approach/ Implementation (Continued)
Design, develop, and implement dynamic IT infrastructure to analyze, maintain, archive, and disseminate flood maps and associated data for North Carolina Flood Mapping Program Present and distribute mapping data,
associated reports, and other Framework data layers to public via Internet
Final system design will be completed byJune 2001
Operable system will be implemented bySeptember 30, 2001
Program Approach/ Implementation (Continued)
Contracting approach for procuring engineering and mapping services Qualifications-based selection
Greenhorne & O’Mara Team
Watershed Concepts Team
Development of Mapping Activity Statements
Development of process to vet, resolve, and document program issues and establish policies
Established Program website for public
ncfloodmaps.com
Program Approach Negotiating product specifications
that meet State, FEMA, and client needs
Project management tools, such as: GIS-based Scoping database
MS Project model
Collaborative Web site
Developing Policy & Procedures Manual
Developing Higher Standards Guidebook for community officials
Program Funding
In August 2000, North Carolina General Assembly allocated funding for first six river basins ($23 million)
Additional State funding from Partners ($2.75 million)
FEMA has contributed $6 million, as well as in-kind professional services
North Carolina is also working with other Federal partners to secure additional funding

Community Review
Scoping
Research/inventory all available elevation, flood hazard, and digital base map data
Assess existing flood hazard data on effective FIRMs
Determine appropriate technical method for developing up-to-date flood hazard data and establishing priority level
Scoping (Continued)
Conduct outreach activities to determine needs for updated FIRMs
Identify data that need to be developed or acquired
Determine proposed scales, paneling scheme, and format for digital FIRM production
Map Production
Updated engineering analyses and floodplain mapping
State has contracted with private-sector firm(s) to conduct this work
Work will include: Conducting flood hazard analyses
and producing updated digital FIRMs Designing and implementing the IT
Infrastructure
Community Review
