Many residences that had never appeared in an area designated as a special flood hazard may now be located in one of the color zones that identify areas at risk of flooding. Anyone living in a high risk zone with a federally insured mortgage will be be required to purchase flood insurance.
The maps colors have the following designations:
Red — The area could be affected by the 1 percent annual chance of flooding with additional hazards due to storm-induced velocity wave action.
Blue — The area could be affected by the 1 percent annual chance of flooding.
Orange — The area could be affected by a 1 percent annual chance shallow flooding.
Pink/purple — A moderate flood hazard area.
Yellow — A moderate flood hazard area.
Gray — An area subject to inundation by the 1 percent annual flood event. The red, blue, orange and gray zones are in the special flood-hazard area. The pink/purple and yellow zones are outside of the special flood hazard area and do not require mandatory flood insurance .
