The Federal Emergency Management Agency (FEMA) Has Issued New Preliminary Flood Maps Dated December 31, 2019 Affecting City of North Port and Sarasota County Property Owners

Know your flood risk! FEMA has revised flood maps in the City of North Port and Sarasota County to incorporate storm surge, high tides, wave action in addition to freshwater inputs. Preliminary flood maps dated December 31, 2019, are available and can indicate whether your property’s flood risk has changed. If your risk has changed, flood insurance may be required by your lender when the new flood maps become effective.

Please click here to view an informative PowerPoint presentation on the Preliminary Risk Map dated Dec 31, 2019.

Please note that FEMA used 2007 topographic data in North Port to create the Preliminary Risk Map dated Dec 31st, 2019.  Houses constructed on fill after 2007 may be out of the high risk flood zone AE but this not is reflected in the preliminary maps.  Property owners may formally appeal the new maps with FEMA.  At the open house public meetings, FEMA and local officials will explain the process and discuss how to file an appeal or comment during the 90-day public comment/appeal period after March 5, 2020.  Property owners can submit an application for a Letter of Map Amendment (LOMA) or a Letter of Map Revision Based on Fill (LOMR-F) with FEMA.   Survey information such as an Elevation Certificate is required to establish that a property or structure is not in the high risk flood zone AE. For more information see the FEMA website.  The City’s webpage on entitled “MAP APPEAL, FLOOD INSURANCE, AND LETTER OF MAP AMENDMENT” can provide additional information.
