What is the difference between FEMA-designated zones A, AE and X?: Zone A is an area of the 100-year floodplain that has not been studied in sufficient detail to determine the water surface elevation of the 100-year flood. Zone AE is the area of the 100-year floodplain with the elevation of the 100-year flood available and the floodway designated. Zone X is an area inundated by the 500-year storm or areas outside of land inundated by the 500-year storm.

4. I have an easement on my property. What is it for?

-General utility easement is for any underground or above ground utility such as gas, electric, water, sewer, etc

-Specific utility easement (such as electric easement or water easement), relates solely to that specific utility only (a gas line cannot be in a water easement)

-Access easement grants access across the property to serve another property

-Floodplain / Drainage easement is dedicated to protect the floodplain and covers anything stormwater-related, including the following:

Underground storm sewer including inlets and outfalls
Above ground drainage, such as a channel, flume, or detention pond
