2 Program Product Comparisons Traditional Regulatory Products Flood Risk Products DFIRM Database Traditional products are regulatory and subject to statutory due-process requirements Risk MAP products are nonregulatory and are not subject to statutory due-process requirements 2

3 Risk MAP Flood Risk Products Flood Risk Products Flood Risk Report Summary of local flood risk Flood Risk Map Utilizes Flood Risk Assessment to visually depict flood risk Flood Risk Database Raw data and results from flood risk assessment Flood Risk Datasets Flood Risk Assessment HAZUS loss estimation, identifies location Enhanced Coastal Depth Grids Illustrate depth and velocity of flooding Flood Risk Database = Flood Depth and Analysis Grid + Risk Assessment + Changes Since Last FIRM + Areas of Mitigation Interest Flood Risk Assessment = Local Inventory Data + HAZUS Loss Estimation 3

4 Using Changes Since Last FIRM for Identifying Actions Changes Since Last FIRM Communities and homeowners can use this to identify the impacts of new maps on the regulatory Special Flood Hazard Area (SFHA) Also reveals new areas that may need mitigation actions either for existing assets or for future planning 4

5 Using Depth and Analysis Grids for Identifying Mitigation Actions Baltimore Harbor Under 2ft - 3ft of water Better information on depth and velocity of flooding More information on higher probability (10 & 25 year) flood events These provide enhanced data to develop a more accurate Benefit Cost Analysis (BCA) for mitigation projects, a big step towards implementation 5

6 Using Flood Risk Assessment for Identifying Mitigation Actions Total Economic Loss in $1000 Baltimore Harbor $0 - $45,000 $45,000 $220,000 $220,000 $540,000 $540,000 - $4,100,000 Identifies areas of higher flood risk Quantifies potential future flood losses to existing structures Identify areas requiring higher building code requirements Supports mitigation plan updates and disaster recovery planning 6

10 Where is the data? FEMA Map Service Center The official public source for flood hazard information produced in support of the National Flood Insurance Program ( NFIP). Includes DFIRM Database + Risk MAP Flood Risk Products Maryland Flood Map Status Includes upcoming meeting dates + milestone dates Access to training, LOMR status + fact sheets Maryland DFIRM Outreach Designed to guide homeowners/renters as well as communities through the process of determining their current flood risk as well as future flood risk based on the preliminary Digital Flood Insurance Rate Maps (DFIRMs). 10

11 New Approach - Total Exposure in Floodplain (TEIF) version 1.0 FEMA Region IV released 2010 Census and ACS data integrated into HAZUS Updated to census tracts, applying 2012 RS Means valuations. Includes update to the 2010 nationwide total exposure data. Development of Total Exposure in Floodplain (TEIF) - Create a dataset using Arc GIS and MS Excel. Determine an approximate value of Total Exposure in the SFHAs. (Effective & Preliminary Maps from May 2013) Use in lieu of the AAL study. Utilized for relative comparison for community engagement and action potential ranking. TEIF - Value in $ 0-3,000 3,000-10,000 10,000-30,000 30,000-70,000 70, ,000 CLEAR Risk! 11

12 GIS Solution A Three Step Process Step 1 Transfer 2000 Census Tract Total Exposure Dollar Values (Updated by Region IV) to 2010 Census Blocks Census Building Counts were used to distribute the 2000 Census Tract Dollar amount to the 2010 Census Block units through binomial areal interpolation. Step 2 Assemble a statewide SFHA layer. Effective DFIRMs in the NFHL, Current Draft Preliminary DFIRMs, Preliminary DFIRMs, DFIRMs at LFD, or newly effective DFIRMs Step 3 Intersect the 2010 Census Block Geography with Total Exposure Dollar values and the statewide SFHA Areal Interpolation of 2010 Census Block in SFHA resulted in the ultimate TEIF value 12

13 GIS Solution Step 3 + A B = TEIF = C 13

14 Updated Approach - Total Exposure in Floodplain (TEIF) version 2.0 FEMA Region IV released 2010 Census and ACS data integrated into HAZUS Updated to census tracts, applying 2012 RS Means valuations. Includes update to the 2010 nationwide total exposure data. Development of Total Exposure in Floodplain (TEIF) version Create a dataset using Arc GIS. Determine an approximate value of Total Exposure in Special Flood Hazard Areas (SFHAs). Use Building Counts from LiDAR extracted buildings footprints. Apply Dasymetric approach to eliminate loss estimates being applied to undeveloped areas within Census Blocks. 14

15 Extracting Building Footprints from LiDAR Data planar surface recognition Source: PAMAP Aerial Photography (2 D) provides a visual interpretation of on the ground features. Source: Google StreetView Source: PAMAP LiDAR Data ( 3 D) provides the ability to automate feature extraction of planar surfaces. 15

16 Automated and Manual Process using TerraScan Software and ArcGIS Automated Part 1 TerraScan Software (runs on MicroStation) Building Classification Tool Input needed: Point rich LiDAR file (.las) file with ground classified. Manual Part 2 Automated process is not fool proof. It s incredibly cost efficient, but not 100 % accurate. There will be omission (missing footprints) and commission (footprints where no building exists) errors. Manual clean up involves spending time with an aerial photo and intensity imagery derived from the LiDAR data. Produces rough polygon shapes through export to ArcGIS. Automated process can clean up rough outlines. Rough Realistic 16

17 Dasymetric Approach to eliminate loss estimates in undeveloped areas Follow Dasymetric Methodology for Hazus Functional Enhancements for General Building Stock exposure distribution Dasymetric Methodology = Intersect National Land Cover Dataset (NLCD 2011) - TIGER polygons to filter out non-built-up areas Only difference was to use a M Resolution Maryland Land Use Land Cover Dataset. Matched Maryland Land Use Codes with the NLCD codes for consistency. 17

18 TEIF in Maryland TEIF 1.0 is available for all counties in MD Enhanced HAZUS Delivered in Coastal footprint TEIF 2.0 is available in Risk MAP Riverine Projects Implementation priorities Counties with high resolution topo data Preferably LiDAR, OR Counties with a building shapefile Priority given to areas with.. High risk to flooding Increasing population in the SFHA Deficient geospatial data Building replacement value, Age, Total built area, FFE, Occupancy type (land use) 18

25 + Broad Agency Announcement (BAA) 25 GOAL - Make the process for partnering with 3DEP transparent and accessible Primary source of information on process and timing Proposes project for USGS funding Negotiates terms with USGS How USGS coordinates Previous Process Liaisons Liaisons Liaisons Liaisons bring partners and projects together Broad Agency Agreement Information publicly available to all online Partners Partners Common interests identified through open reporting of annual and multi-year plans

26 + Broad Agency Announcement 26 Timing

27 + Broad Agency Announcement 27 Status and Plans First year was an opportunity to learn by doing and we have adopted proposer feedback into what is needed to improve BAA process. Major areas for planned development Coordination current thinking is to hold open 3DEP coordination meetings 1-2 times each year in each state or region Annual and multi-year plans make Federal, state and other plans and areas of interest available online, as the planned companion to the available status of the inventory Current BAA never closes, major activity for FY 15 complete. FY 16 BAA announcement scheduled for July

28 Maryland National Hydrography + Dataset Current Status MDE Stewardship 28 No unified state approach, agency applications 1:24,000-scale USGS performing regional data inspection/improvement Move to 2400-scale hydrography statewide using available high-resolution data in order to bring hydro features in scale with elevation and orthoimagery. Based on success with existing New Jersey statewide scale NHD/WBD

29 + Planned NHD Activity 29 MDE to Run pilots, then contract data acquisition NHD Training at DC Dept. of Environment 1:2,400-scale pilot by MDE-Washington County using 2014 orthoimagery, 2012 lidar, modified New Jersey collection parameters Second pilot with DDOE for Anacostia also at 1:2400 using QL2 lidar to be delivered November-ish and 2014 orthoimagery. DC has similar data, and is also planning scale hydrography Suitable for lidar derived storm-water catchments, BMPs, 14- digit HUCs(maybe 16-digit HUCs?)
