Frequently asked questions

Do I need flood insurance in Gilchrist County?

Lenders require flood insurance on a federally backed mortgage when the building is in one of FEMA's high-risk zones, the ones starting with A or V. The map that sets those zones in Gilchrist County took effect on January 19, 2018. Outside those zones insurance is optional, but claims come from moderate- and low-risk zones too, so it's worth checking the zone and the floor height of the exact home.
