An aerial photograph captioned by BeckerFraserPhotos, "The Avon River windings its way through densely pupulated housing. The Gayhurst Road bridge can be seen. The piece of land circumscribed by the loop of the river is all zoned red, as is the land to the left of the photo. On the right, most of the land is zoned green or orange".

Photograph captioned by BeckerFraserPhotos, "Demolition site of the Allan McLean building, on the corner of Colombo Street and Oxford Terrace. The PricewaterhouseCoopers building is behind. The green digger is feeding the yellow concrete muncher while the red digger redistributes the munched up concrete".

A video of a play produced and performed by students from Avonside Girls' High School. The play was created for the Theater Federation One Act Play Festival, on the topic of the Christchurch rebuild. The students modeled the play on the epic theatre style, aiming to emotionally affect and enact change in their audience.

A photograph of the partially-completed Green Room garden on Colombo Street. Crack'd for Christchurch's armchair and mosaic artworks are on a platform in the back. The armchair and ottoman have been wrapped in tarpaulins until their unveiling. Wire fences have been placed around the section as a cordon.Crack'd for Christchurch comments, "Flora and Otto waiting for their big day, with the garden still to be finished."

A photograph of the back page of a Christchurch City Council form. The form allowed contractors to apply for the authorisation to enter the Christchurch Red Zone after the 22 February 2011 earthquake. Information on the back reads, "What does this authorisation mean for me? I am wearing appropriate personal protection clothing and equipment. At all times DO NOT enter any red placarded building. You may enter a yellow placarded building for a period of time (no longer than 30 minutes) and follow the instruction of the escorts. A green placarded building may be accessed for longer periods. Please note: do not enter any buildings which are not for the purpose of your authorisation".

The photograph has been captioned by BeckerFraserPhotos, "Burwood School is at the top right of this photograph near the intersection of Lake Terrace Road and New Brighton Road. This area is mostly zoned residential green".

The Canterbury region of New Zealand experienced a sequence of strong earthquakes during 2010-2011. Responses included government acquisition of many thousands of residential properties in the city of Christchurch in areas with severe earthquake effects. A large and contiguous tract of this ‘red zoned’ land lies in close proximity to the Ōtākaro / Avon River and is known as the Avon-Ōtākaro Red Zone (AORZ). The focus of this study was to provide an overview of the floodplain characteristics of the AORZ and review of international experience in ecological restoration of similar river margin and floodplain ecosystems to extract restoration principles and associated learnings. Compared to pre-earthquake ground levels, the dominant trend in the AORZ is subsidence, together with lateral movement especially in the vicinity of waterway. An important consequence of land subsidence in the lower Ōtākaro / Avon River is greater exposure to flooding and the effects of sea level rise. Scenario modelling for sea level rise indicates that much of the AORZ is exposed to inundation within a 100 year planning horizon based on a 1 m sea level rise. As with decisions on built infrastructure, investments in nature-based ‘green infrastructure’ also require a sound business case including attention to risks posed by climate change. Future-proofing of the expected benefits of ecological restoration must therefore be secured by design. Understanding and managing the hydrology and floodplain dynamics are vital to the future of the AORZ. However, these characteristics are shared by other floodplain and river restoration projects worldwide. Identifying successful approaches provides a useful a source of useful information for floodplain planning in the AORZ. This report presents results from a comparative case study of three international examples to identify relevant principles for large-scale floodplain management at coastal lowland sites.
