![]() National Flood Insurance Program (NFIP) has recently released new flood insurance rating procedures meant to equitably distribute, easier to understand the cost of insurance for potential flood damage based on the property’s flood risk. The Federal Emergency Management Agency (FEMA) has taken steps to assess the flood risk more effectively to better reflect a property’s flood risk. New Flood Insurance Information from FEMA Risk Rating 2.0 The 100-year flood is a standard used by the NFIP for floodplain management and to determine the need for flood insurance. The 100-year floodplain is the land that is predicted to flood during a 100-year storm event, which has a 1% chance of occurrence in any given year. Planning early is essential because it normally takes 30 days after purchase for a flood insurance policy to go into effect. ![]() For more information on federal insurance and the premium discount, call your insurance company and refer them to this webpage or our annual Floodplain and Outreach notices.

The maps are based on model outputs and do not account for future conditions such as new construction, City infrastructure upgrades, or other changes that may affect flooding. The model's calculations take into account projected sea level rise and storm surge causing elevated bay levels. The map was created using a hydrologic and hydraulic computer model, utilizing a digital elevation model created from 2010 LiDAR data and information on existing City-owned infrastructure. It also does not show areas in the City that may experience shallower and/or more localized flooding in a 100-year storm, or areas of the City that may flood in storms larger than a 100-year storm.
