North Carolina Floodplain Mapping Program

Cooperating Technical State

State Response / Strategies

• Strategy 1 - Establishment of a statewide program to acquire, process and disseminate current, accurate, and detailed elevation data, flood hazard studies, reports, and maps (hard copy and digital).

• Strategy 2 - Establishment of North Carolina as a Cooperating Technical State (CTS) through the FEMA Cooperating Technical Partners Program. This designation would establish North Carolina as the custodian of the Flood Insurance Rate Maps.

Program Objectives and Deliverables

• New / up-to-date / improved Flood Insurance Rate Maps:  Study on a Basin by Basin  Issued on a Countywide Basis • New DFIRMs (new H&H studies) for all North Carolina by FY 2007-08 • New detailed, accurate elevation data • Reduction of time needed for post-preliminary review and appeals process for new FIRM maps (6 months) • Better notification and dissemination of information about new and revised maps

Program Objectives and Deliverables -

continued

• On-going program for updating and maintaining FIRMs • Better equipped and informed post-event mitigation activities as a result of updated flood risk maps • Cost-effective data sharing through the implementation and operation of an inter-operable Geographic Information System • Internet web application providing cost-effective upload, download, management, and dissemination of digital data and maps (24 x 7 / free access) • Implement a real-time flood inundation and forecast mapping system (flood warning)

Floodplain Mapping - Phases

Phase I—blue (December 2003) Phase II—gold (December 2004) Phase III—green (December 2006)

Floodplain Mapping – Old Map vs. New Map

Programmatic / Operations - Priniciples

• Leverage efficient and effective technology for more efficient digital / map modernization for new maps / future updates (GIS, LIDAR, etc.) • Collect complete elevation data coverage in North Carolina • Study as many miles of stream as need and possible (1 sq. mile basin threshold / efficient limited-detail approach) • Requirement for hard copy (snapshot) and digital (living) version – different purposes, valued products for each • Emphasize / Establish digital data sharing with counties / municipalities • Leverage program deliverables to defray the overall cost and further implement other ( e.g. flood warning ) • Strong, upfront community involvement and buy-in • Documentation is Required (Business Rules and Procedures) • No new wheels – Share everything / Co-opetition

Data Acquisition – Public vs. Private

• Assessment / scoping of map needs (State of NC / NC Communities) • Digital base maps (State of NC / NC Communities) • Acquisition of elevation data (RFQ) • Engineering studies (RFQ) • Digital flood insurance rate maps (RFQ) • Quality assurance/quality control (Geodetic Survey / 3 rd Party) • Information technology architectural design and implementation (RFQ) • Real Time Flood Forecasting and Inundation Mapping (State of NC / FEMA / USGS / NWS)

Current Program / Operations - Structure

• NCFPMP has established a distributed program structure utilizing multiple agencies as leads: – – – – – –

NCFPMP

– Overall program/policy development and management , contractual management, operations management, H&H analysis , scoping, outreach, post-preliminary

NCGS

(3 rd – (lead partner) Elevation acquisition, elevation quality control party, independent surveyors

NC CGIA

– (lead partner) Base map acquisition / review, DFIRM review, IT design and implementation

FEMA

– Overall CTP partner , concurrence on policy and maps, post preliminary (regulatory responsibilities), financial support

Dewberry

– H&H concurrence review, DFIRM and DFIRM database concurrence review, community mapping needs / scoping support, program and policy support

CTS Committee

– policy / program direction (advisory), program / product feedback, inter-agency coordination and collaboration

Current Program / Operations – QA / QC

• NCFPMP has established a distributed QA / QC program structure utilizing multiple agencies as leads: •

QA / QC for elevation data – surveyors / FEMA-Dewberry NCFPMP / NCGS / 3 rd party

QA / QC for DFIRM panels, database, reports – CGIA, FEMA-Dewberry NCFPMP,

QA / QC for Hydraulic & Hydrologic studies FEMA, and Dewberry NCFPMP,

QA / QC for Information Technology Infrastructure – NCFPMP, CGIA, IRMC, FEMA

CTS Program Steps / Milestones

• August 15, 2000 , North Carolina General Assembly reallocates $23.2 million from Hurricane Floyd Reserve to Floodplain Mapping – Phase I • September 15, 2000 , State of North Carolina and FEMA signed MOA transferring primary responsibility for NC FIRMs to North Carolina • October 2000 , North Carolina holds first CTS Committee Meeting • November 2000 , qualified two prime firms (WSC and G&O) to do the elevation acquisition, engineering and surveying, DFIRM generation, IT design and implementation • January 2001 , issued first delivery orders to both firms for elevation acquisition for Phase I area

CTS Program Steps / Milestones

• September 2001 , General Assembly transferred NCFPMP from OSBPM to CCPS, sending NC CGIA and NCGS to DENR • November 2001 , North Carolina General Assembly reallocates (through legislation) $ 9.0 million from Hurricane Floyd Reserve to Hurricane Floyd Reserve – Phase I and II • January 2002 , OSBM puts hold on all state funds due to budget shortfall • January 15, 2002 , Onslow County maps are submitted to community (post-preliminary process) • April 30, 2002 , North Carolina Floodplain Mapping Information System (NCFMIS) is certified by IRMC and goes live on the web • September 2002 , National Weather Service Flood Warning Grant approved

CTS Program Steps / Milestones

• October 2002 Reserve Program” , North Carolina General Assembly reallocates (through Appropriation Bill) $ 9.0 million from Hurricane Floyd Reserve to Hurricane Floyd – “To be used to leverage / maximize federal and state funds to continue the Floodplain Mapping • November 2002 , Issue Delivery Order for Scoping Tool / Application to be used in Phase II • March 2003, Qualified two additional Prime Engineering Firms (AMEC and Arcadis) • December 2003 , Submitted Draft State Map Modernization Business Plan (2004-09)

RFQ Highlights / Contractual Approach

• NC FPMP intends to award one IDIQs to a private sector engineering firm • Selection based on demonstrated competence and qualifications (G.S. 143-64.31) • 2 year contract with three / 1 year renewal options • No joint ventures allowed / Prime Firms • Letter of qualifications due by interviews be held between April 13, 2004 • An evaluation of the submitted letters will be conducted • A short list of firms will be determined with subsequent May 2004 • All firms submitting Letters manager(s) licensed as a Professional Engineer with the NC Board must be equipped with • Contractor must have primary contract office within 25 miles of the State Government Complex in downtown Raleigh, N.C. within three months of contract signing.

RFQ Highlights / Contractual Approach

• • Firms are required to identify project team members and their specific proposed roles on the project.

• Regarding the evaluation of qualifications, note the emphasis placed on project management, quality control, and capacity (experience and manpower) for doing the work.

• All work must meet FEMA requirements and meet or exceed North Carolina defined requirements (IT / Database) • Vertical Management Approach • Bi-weekly joint contractors meeting • CTS Committee Meeting
