Stopbank completion marks major milestone in flood-repair project
The completion last week of the new section of the College Road stopbank in Edgecumbe marks a major milestone in the Bay of Plenty Regional Council’s April 2017 Flood Repair Project.
Engineering Team Leader Peter Hay says contractors are now working on the removal of the existing, temporary stopbank and reinstatement of the berm, a process which will take a further two weeks of good weather.
“When that final stage is complete, the town’s flood defence will be at the full design standard agreed in Council’s Rivers and Drainage Asset Management Plan.
The relocation of services such as communications cabling and storm water systems and the construction of the new road have been happening in parallel with the stopbank work. Services are now complete and the foundation of the road is in place and our aim, again weather permitting, is to have the road completed in mid-September,” Mr Hay says.
“Following the 6 April 2017 breach of the floodwall, work began on a temporary stopbank as soon as water levels allowed. Council then went through a process that involved geotechnical investigation to inform the design of the new stopbank, community consultation on the design, resource consent and tendering for the work.
At the same time, Council entered into negotiations to acquire the properties directly across from  the breach. We gained possession of those 12 properties and part-properties in October 2017, after which the area was cleared to enable the stopbank construction and road realignment,” Mr Hay adds.
The April 2017 weather events caused damage to 520 sites across the Council’s rivers and drainage networks.
Bay of Plenty Regional Council Flood Recovery Project Manager Paula Chapman says the Rangitāiki-Tarawera Scheme was the worst affected, accounting for more than half of the $45m repair budget.
“The College Road stopbank and associated work is the single biggest site, with an estimated budget of $5.6m and was clearly the highest priority repair.
The region-wide repair project has seen damaged sites prioritised, based on the risk of the damage becoming worse, the consequence of that occurring, any impact to community assets, and the practical ability to complete the work required. Repairs have been completed to date on 119 of the high priority sites, including 62 on the Rangitāiki-Tarawera River Scheme.
As work progresses, the medium and low priority sites will be monitored and reassessed. It’s possible that towards the end of the project some low priority sites will have stabilised and work may not be required but, as it stands, the region-wide project is scheduled to be completed by 30 June 2021.
The community can monitor progress on our web and project pages (,” Ms Chapman concludes.
