MultiHazard Flood Map Modernization NOAA Height Mod Conference

Multi-Hazard Flood Map Modernization NOAA Height Mod Conference 12/1/06 Dave Jula, Michael Baker Jr. , Inc.

Introduction Flood Map Modernization Accurate information about risks is the first step in preventing and reducing losses.

Introduction Flood Map Modernization To support the vision, “A Nation Prepared, ” the Federal Emergency Management Agency (FEMA), has undertaken the Map Modernization effort to update the Nation’s flood hazard maps.

Map Modernization Objectives Enabling Technology Flood Map Modernization Effective Program Management Provides for the Efficient use of National Resources Establishes Premier Data Collection and Delivery System Partners Delivering Results Builds and Maintains Mutually Beneficial Partnerships Creates Better Informed Users Empowering the User Community

Mapping Information Platform (MIP) What is the MIP? Web-Based Technology that Enables the Management, Extraction, Sharing, and Production of Map Modernization Data Flood Map Modernization How Does it Help? § Proactive Centralized Project Management and Tracking § Standard Data Collection Search and Storage § Free Tools Available

MIP Flood Map Modernization Tracking and Management Tool for Map Mod • Over 1, 290 Active Studies • Over 20, 000 MT-1 s (LOMAs) • Over 1, 400 MT-2 s (LOMRs) • Over 20, 000 Communities • Over 60 Contractors • Over 200 CTPs http: //hazards. fema. gov 4 3 Identify Problem by Reviewing Project Summary and Reports Perform task and update MIP

MIP: Repository The geospatial platform will be the repository for the national GIS data layer and will store the following: • Final Digital Flood Insurance Rate Map (DFIRM) data • Intermediate data, including the outputs of key steps used to create the DFIRM data. § Scoping § Survey § Elevation § Hydrology and hydraulics modeling data § Base Flood Elevations (BFEs) § Flood outlines and other pertinent data Flood Map Modernization

Elevation Data Capture Standards NDEP/NDOP Flood Map Modernization

Purpose of Data Capture Standards Flood Map Modernization § Provide a consistent framework for collection, storage, and retrieval of the data needed for a Flood Insurance Study (FIS) § Describe what needs to be captured from digital data that was used in the FIS § Capture key data required for model maintenance and quality control § Verify that the data can be accessed easily and used for other projects

Survey Data Flood Map Modernization

Survey Data § Complete digital submission of all survey data files, photographs, sketches, and notes § Data specifications for surveyed cross sections and structures • Cross sections • Bridges • Culverts • Dams • Elevation Reference Marks • High water marks • Levees Flood Map Modernization
