Flood insurance and building rules in Gage County
Lenders watch the zone closely on Gage County properties. If a barn or house outside Adams falls inside an A or V zone and secures a loan from a federally regulated or insured lender, flood insurance is mandatory, provided the community near Adams takes part in the National Flood Insurance Program. For a Gage County home in shaded or unshaded X, coverage is optional, although a lender in Nebraska can still ask for it. Where a structure near Adams looks higher than the shading suggests, the titleholder can ask FEMA for a Letter of Map Amendment (LOMA), supported by elevation data from a licensed land surveyor. Adding on to a house near Cortland inside the zone typically needs a floodplain permit, and the building office serving Cortland explains the steps.
