During the 4 September 2010 Canterbury earthquake , Avonside suffered a large amount of liquefaction . In particular Keller Street , Bracken Street , Retreat Road and Cowlishaw Street were left with large areas covered in water and grey silt . Avonside Drive also experienced a great deal of damage with cracked roads and buildings . Power and water were lost , in some cases for several days , and there was extensive damage to the sewer system . The more devastating 22 February 2011 Christchurch earthquake further damaged infrastructure and houses in the suburb . Liquefaction and flooding was more prominent than in September , along with the damage to roads , and many houses were more severely damaged along with the land they were built on . Power was lost for two to three weeks for many residents and for most houses the sewer infrastructure needed to be replaced or repaired . The New Zealand Army and many other volunteer organisations based in Christchurch ( especially the Student Volunteer Army and the Farmy Army ) helped residents remove silt from their sections because of the sheer volume , with many streets having large mounds piled up on the side of the road . Local electorate MP Brendon Burns , in association with local community leaders , hosted meetings at Retreat Park ( a local park on the corner of Retreat Road and Patten Street ) to inform residents of necessary information such as the provision of water and progress of power being re-connected
