Categories breaks: Each FRM will may use a unique range of Total loss for 1% annual chance event value for each category. Range choices should consider clarity of showing those locations greatest relative risk and map scale issues. A suggested starting point could be using Natural Breaks (Jenks) within ArcGIS to classify into 5 categories. of Mitigation Interest Derivation of all of Areas of Mititgation Interest Datasets is described in Appendix N, along with detailed definition and cartographic considerations. This is an enhanced Flood Risk dataset choice and will only be included on the FRM when included in the Flood Risk Products choices identified in the Final Discovery Report and Project Charter. Accredited Levees Data source: compiled during the project lifecycle from a variety of sources. Data used to: identify accredited levees that may cause risk. Data considerations: The FRM may only show a subset of all accredited data stored in the FRD. De-accredited Levees Data source: compiled during the project lifecycle from a variety of sources. Data used to: identify de-accredited levees that may cause risk. Data considerations: The FRM may only show a subset of all unaccredited levee data stored in the FRD. Dams Data source: compiled during the project lifecycle from a variety of sources. Data used to: identify dams that may cause risk. Data considerations: The FRM may only show a subset of all dams data stored in the FRD. Coastal Structures Data source: compiled during the project lifecycle from a variety of sources. Data used to: identify coastal structures that may cause risk. Data considerations: The FRM may only show a subset of all coastal structure data stored in the FRD. Stream Flow Constrictions Data source: compiled during the project lifecycle from a variety of sources.
