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

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
