Environment Canterbury Regional Council (CRC) has a statutory function under the Soil Conservation and Rivers Control Act 1941 to manage land use within the region to prevent and mitigate damage caused by floods and erosion (see s126 of the Act).
This work is part of the flood protection and river control work for the benefit of the Waiau Town River Rating District. This project is part-funded through the central government’s COVID-19 Response and Recovery Fund administered by the Provincial Development Unit (PDU) in the Ministry of Business, Innovation and Employment.The Waiau Township has been subject to numerous flood events from both the Mason and Waiau rivers, post-colonial settlement in the mid-19th century. Numerous ad-hoc stopbanks have been constructed over the past century, the earliest dating between 1907 and 1922 by the Waiau Riverside Protection Board. Most of these works were undertaken in a reactionary manner, during or following flood events.
Modelling and investigation undertaken by members of CRC’s Natural Hazards team in 2015 confirmed the risk that the Mason River poses to the township, especially in the section immediately upstream of the Inland Road bridge where a vulnerable, earthquake damaged stopbank is located. The work proposed within this contract seeks to improve the level of flood protection to Waiau through the remediation and strengthening of two existing stopbanks on Inland Road and through the construction of a new stopbank which will border the Western side of the town.
