Applicants may easily upload all information, supporting documentation and check the status of their LOMA application online. The Online LOMC is a convenient way to request a LOMA from FEMA. Online Letter of Map Change (LOMC) Training Tutorial The LOMA/LOMR-F Tutorial series also provides users with an online tool to complete portions of the required forms. The LOMA/LOMR-F Tutorial Series explains these map change application processes, including all required forms and information. National Flood Insurance Program (NFIP) Revisions And Amendments Letter of Map Amendment (LOMA)/Letter of Map Revision Based on Fill (LOMR-F) Tutorial Series The RASPLOT tutorial demonstrates the use of the software to generate flood profiles from HEC-2 and HEC-RAS models. RASPLOT Version 2.1.0 replaces FEMA's FISPLOT program, which was previously used to develop flood profiles. The Quick-2 Tutorial exposes the user to single-lot and multiple-lot case studies, demonstrating much of the program's functionality along the way. Quick-2, Version 2.0, is the latest version of a hydraulic analysis program used to compute water-surface elevations in open channels of all types. The tutorial will demonstrate the many functions of the program including entering, visualizing, tabulating and charting data and performing coastal engineering analyses within a user-friendly environment. The Coastal Hazard Analysis Modeling Program (CHAMP) is a software program designed to enable the user to perform storm-induced erosion treatments, wave height analyses and wave runup analyses associated with coastal flood hazard assessments. The cHECk-RAS tutorial will demonstrate the many functions of the program, including basic information about the U.S. cHECk-RAS TutorialĬHECk-RAS is a program designed to verify the validity of an assortment of parameters found in the HEC-RAS hydraulics program. Base flood elevations derived from detailed analyses are shown at selected intervals within these zones.The following are software programs with online tutorials. These areas have a 26% chance of flooding over the life of a 30 year mortgage. VE - Coastal areas with a 1% or greater chance of flooding and an additional hazard associated with storm waves. Average flood depths derived from detailed analyses are shown within these zones. Base flood elevations derived from detailed analyses are shown at selected intervals within these zones.ĪO - River or stream flood hazard areas, and areas with a 1% or greater chance of shallow flooding each year, usually in the form of sheet flow, with an average depth ranging from 1 to 3 feet. These areas have a 26% chance of flooding over the life of a 30 ‐ year mortgage. Because detailed analyses are not performed for such areas no depths or base flood elevations are shown within these zones.ĪE - The base floodplain where base flood elevations are provided.ĪH - Areas with a 1% annual chance of shallow flooding, usually in the form of a pond, with an average depth ranging from 1 to 3 feet. The SFHA designations which appear within Bay County are explained further below.Ī - Areas with a 1% annual chance of flooding and a 26% chance of flooding over the life of a 30 year mortgage. The areas of minimal flood hazard, which are the areas outside the SFHA and higher than the elevation of the 0.2-percent-annual-chance flood, are labeled Zone C or Zone X (unshaded). Moderate flood hazard areas, labeled Zone B or Zone X (shaded) are also shown on the FIRM, and are the areas between the limits of the base flood and the 0.2-percent-annual-chance (or 500-year) flood. SFHAs are labeled as Zone A, Zone AO, Zone AH, Zones A1-A30, Zone AE, Zone A99, Zone AR, Zone AR/AE, Zone AR/AO, Zone AR/A1-A30, Zone AR/A, Zone V, Zone VE, and Zones V1-V30. The 1-percent annual chance flood is also referred to as the base flood or 100-year flood. SFHA are defined as the area that will be inundated by the flood event having a 1-percent chance of being equaled or exceeded in any given year. Flood hazard areas identified on the Flood Insurance Rate Map are identified as a Special Flood Hazard Area (SFHA).
