![]() The Q3 cannot be used as the official NFIP map for site design or flood risk determinations. FEMA has also produced Q3 Flood Data, which includes certain features of the FIRM, and may be used for insurance purposes and planning activities. More recent flood map products include digital FIRMs, which are created using digital methods and can be incorporated into a community's Geographic Information System (GIS). Data displayed on the WV Flood Tool are directly sourced from FEMA's. The FHBM is an older version of a flood map and is based on approximate data. The West Virginia Flood Tool is designed to provide floodplain managers, insurance agents, developers, real estate agents, local planners and citizens with an effective means by which to make informed decisions about the degree of flood risk for a specific area or property. The FBFM is no longer produced current FIRMs include all of this information. The FBFM is a version of a flood map that shows only the floodway and flood boundaries. At a minimum, flood maps show flood risk zones and their boundaries, and may also show floodways and Base Flood Elevations (BFEs). The FIRM is the most common type of map and most communities have this type of map. In the meantime, to ensure that structures are constructed using the best available information, the New York City Building Code will continue to require new and substantially improved buildings to use the Preliminary FIRMs until a new map is created and adopted by the City.A Flood Insurance Rate Map (FIRM), Flood Boundary and Floodway Map (FBFM), and Flood Hazard Boundary Map (FHBM) are all flood maps produced by FEMA. This ground-breaking step will result in new flood maps that better account for the future risk of sea level rise and coastal storm surge for planning and building purposes, while protecting the affordability of flood insurance - which will continue to be priced against current flood risk. In addition, FEMA and the City will work together to create a new methodology to incorporate the growing risks of climate change and sea level rise. The City’s goal is to ensure FEMA’s Flood Insurance Rate Maps (FIRMs) provide residents with an accurate representation of the city’s current one percent annual flood risk (also known as the 100-year floodplain).įEMA and City officials agreed that the information submitted during the appeal period will be used to revise the Preliminary Flood Insurance Study (FIS) and 2015 Preliminary FIRMs. As a result, FEMA’s modeling overestimates the size (or extent) of the one-percent-annual-chance (aka 100-year) floodplain (i.e., where waters will reach during a flood that has a one percent chance of occurring each year). The City found technical and scientific errors in FEMA’s modeling that overestimate the height of flood waters during a one-percent-annual-chance flood event, the “Base Flood Elevation (BFE),” by between 1 and 2.5 feet across the city. ![]() **In October 2016, FEMA announced that it agreed with the City’s findings,** and that it would work with the City to revise the 2015 Preliminary FIRMs and issue new maps in the coming years that better reflect current flood risk. FEMA provides access to the National Flood Hazard Layer through web mapping services. In June 2015, New York City filed a technical appeal of the Preliminary FIRMs. This area is based on the Limit of Moderate Wave. The issuance of the Preliminary FIRMs and FIS marked the first step in the official flood map update process, which included a public comment and a 90-day technical appeals period. The new FEMA Flood Risk Maps will usher in a new FEMA designated flood zone known as the Coastal A Zone. In January 2015, FEMA released Preliminary Flood Insurance Rate Maps for New York City as well as the Preliminary Flood Insurance Study (FIS) for New York City, a narrative report of the city’s flood hazard. Find out more about understanding FEMA’s Flood Maps. With Risk Rating 2.0: Equity in Action, FEMA addresses rating disparities by incorporating more flood risk. Review your property’s flood map to better understand your flood risk and insurance options. Each flood zone tells homeowners what the risk is for flooding at their property. Your home’s flood risk can change over time due to weather patterns, land development, and erosion. This area is also referred to as the Special Flood Hazard Area (SFHA) or the 100-year floodplain, and is broken down into smaller areas called flood zones. This high risk area has a one percent chance of flooding in any given year, and a twenty-six percent chance of flooding over the life of a thirty-year mortgage. ![]() These maps identify areas that are at high risk to flooding. ![]() FEMA creates Flood Insurance Rate Maps (FIRMs) that highlight flood risk and determine flood insurance and building code requirements.
