Heavy rainfall causing surface flooding and road closures

Monday 24 July, 2017

Most roads in the district have reopened following the floods at the weekend, and Ashburton District Council is reminding drivers to be cautious of flood damage to road surfaces.

A section of Thompsons Track remains closed today due to flooding, and detours are in place between Line Road and Winchmore Lauriston Road. The remainder of Thompsons Track has been reopened, as have most other roads that were temporarily closed by the floods. The only other road that remains closed is Waipuna Road, on the southeast side of the Drain Road intersection.

Potholes and washouts are now a hazard on some roads following the flooding, and Council is urging drivers be mindful of this damage and to drive to the conditions.

Residents who use the stockwater race systems may also experience reduced flows in the stockwater races from today, as these networks are temporarily closed for maintenance. Work is being carried out to clean up the debris caught in the culverts and grates in the races brought on by the flooding. The stockwater race system is expected to be operating normally again in two to three days.

For more information on road closures relating to the floods over the weekend, visit the Council website or check the Council’s Facebook page.

2.30pm Update:

Ashburton District Council is reminding drivers that there is still flooding on the roads and extra caution needs to be taken.

Fulton Hogan has been busy over the weekend during the weather event tending to road damage reported throughout the district.  The roads that are still currently closed are Barkers Road near the Rakaia Gorge and Thompsons Track. Other roads around the district, particularly around Methven, still have water on them and are open to traffic but drivers are urged to slow down and drive to the conditions. 

The floods have caused large numbers of washouts and many more potholes are now evident. The amount of damage on the roads means that there will be a longer recovery programme to repair potholes and washouts, which is expected to go into mid to late August. With another weather event predicted by MetService for next week, this situation is likely to worsen if roads need to be closed again.  All drivers must reduce their speeds when travelling through the district to prevent crashes and/or injuries to themselves or the contractors working on the road during this recovery period.

All boil water notices issued on Friday for Methven, Methven-Springfield, Montalto, and Mt Somers remain in place until further notice.  

For information about road closures and any other issues related to the weather event, listen to the radio or check the Council’s website or Facebook page.

Council cautions drivers that due to the heavy flooding, there will be a number of potholes or washouts exposed that can cause damage to cars.  These may not be visible at night so all drivers need to be wary of areas of heavy traffic as these potholes are more likely to be prevalent.

2:00pm update

Ashburton District Council advises residents that there is still a significant amount of flooding throughout the district and people need to be cautious.

Reports have been received about the worst hit areas with surface flooding on properties and contractors have been called to help clear the drains as quick as they can to alleviate the issues. However, it will take some time for the water to clear and with the improved weather outlook from MetService we expect this issue to resolve itself.

Council is aware that due to the high amounts of flooding that stormwater could be contaminated. If any residents have signs of sewage in surface flooding on their properties, Council is urging you to ring 307-7700 to report this. Avoid any contact with contaminated areas and if the sewage is blocking access to the property or has breached inside, then self-evacuation is advised. If alternative accommodation is not available to you, please contact Council for assistance.

Community Relations Manager Vincie Billante says that Council contractors are working around the clock to address the stormwater issues and drain blockages over the weekend. “Council understands that this is of great concern to residents at the moment,” she says, adding “We appreciate how difficult this event has been for residents and ask for continued patience whilst this work is underway to look after the public’s health.”

9.30am Update:

Ashburton District Council advises the worst of the rainfall has passed, but roads throughout the district are still experiencing surface flooding and more road closures have been necessary, including State Highway One at Racecourse Road heading North.

No Civil Defence Emergency has been declared, but Civil Defence Controller Terry O'Neill is advising

residents to stay off the roads if possible. If travel is necessary the public are urged to drive slowly and to avoid causing further issues with bow wakes flowing into residential properties.

Currently, the following streets are closed to drivers:

No welfare issues or emergencies have been reported from residents aside from reports of water coming onto properties. The flood protection schemes for all major rivers have held up well, but Mill Creek has flooded and water is currently flowing into other stormwater drains and is slowly subsiding. The rain that is still falling in Methven and the high country will not impact on Ashburton's local streams. Residents are advised to be patient as the water will subside in time as contractors work to clear drains during the day.

12.00pm Update:

Heavy rainfall forecast by MetService for Canterbury is causing disruption to transport and localised flooding.

At this stage there is no Civil Defence Emergency, but Civil Defence Controller Terry O'Neill is advising that the weather conditions are being closely monitored by the Canterbury Civil Defence Group.  All roads in the district are being monitored by NZTA, Fulton Hogan and Council to assess the surface flooding. 

Mr O'Neill is advising residents to stay off the roads if possible, but if travel is necessary to be mindful of the surface flooding and drive slowly, especially in residential areas.  "Surface flooding can cause washouts and lift the storm water grates off sumps in the gutters and these won't be visible to drivers, so exposed sumps, washouts or potholes that are hidden under the water can cause serious damage to vehicles and people walking in this weather," he says. "Additionally, the wakes caused by cars travelling through flooded streets can enter into properties and damage people's houses so we are asking the public to be mindful and drive to the conditions."

Currently, the following streets are closed to drivers:

  • State Highway 77 to Methven
  • Bridge Street
  • Kitchener Street

Warnings are in place for the following:

  • Lake Hood Drive is under deep water and residents need to exhibit extreme caution in this area.
  • Detours are in place at Thompsons Track/Mitcham Road corner.
  • Drain Road is closed to 4WD traffic only.
  • Trig Pole Road/Davisons Road intersection is flooding and may be closed later.

Mr O'Neill advises any residents experiencing issues relating to sewage overflows onto their properties can call Council on 307-7700 to report these. Council does not issue any sandbags, so residents wanting to arrange these need to contact ACL directly on 308-4039.
