A cheat sheet released by the Harris County Engineering Department shows how floodplain regulations have changed as of Jan. 1.[/caption]
AE Zone: Includes all areas subject to flooding in a 100-year event
A Zone: Areas subject to flooding in a 100-year event determined using approximate methodologies
V Zone: Areas subject to flooding in a 100-year event along the coast that face additional hazards from storm waves
AO Zone: Areas subject to flooding in a 100-year event along rivers or streams. Average flooding is typically between one to three feet and is related to sheet flow and sloping terrain.
X Zone (unshaded): Area of minimal flood hazard, outside the 500-year floodplain
