# The red zone, the land Christchurch gave back

After February 2011 the Crown classified the damaged residential ground: repair could begin, or "land repair would be prolonged and uneconomic". The red zone is the second answer, 831.7 hectares in 113 mapped areas along the Ōtākaro Avon, the estuary margin and the Port Hills, from the classification that followed the February 2011 shake.
