New Elevation Certificate and Floodproofing Forms
Notice for those in the confluence area, floodplain, and floodway: the Town has received word from FEMA that the Elevation Certificates (EC) have been changed to a new form with an expiration date of November 30, 2018. Please make sure you have the correct version when doing work such as elevating or making any other changes in the Special Flood Hazard  Area. You will notice many formatting changes, including a new building diagram on the Elevation Certificate depicting walkout basements. 
NOTE: Once the links open in a new webpage, download the page as PDFs to computer for content. The content is not accessible through the webpage, but will be upon downloading. Please direct questions to Arielle Hodgson at ahodgson@townoflyons.com.
