Work to remove high-risk woody debris from the lower Waimatā River, targeting a 4km section between the cheese factory and William Pettie Bridge, will be getting underway from today.
The work focuses on debris that built up during Cyclone Gabrielle and subsequent severe weather events. This material can restrict river flow, trap more debris during floods and create hazards for river users and nearby infrastructure.
Woody Debris Programme Manager Rod Sheridan said the lower section of the river was prioritised due to its high use by the community and proximity to residential areas and key infrastructure.
“This part of the Waimatā is well used by recreational groups and the wider community, so it’s important we reduce the risks while keeping the river usable,” said Mr Sheridan.
“The work is targeted at material that poses the greatest risk. It’s not about removing everything but focusing on debris that could move during a flood or block the river.”
The work follows Council’s Large Woody Debris Removal Prioritisation Framework, which helps identify debris that poses the greatest risk in the river.
Work will be carried out in stages over the coming months, with crews starting in two sections - one near Marian Drive working towards William Pettie Bridge and the other near the cheese factory working downstream towards Marian Drive.
Work will use a range of methods depending on the location and type of material, such as cutting and removing large logs, clearing smaller debris and removing underwater material where required.
Mr Sheridan said care has been taken to plan the work in a way that minimises environmental impacts.
“Vegetation that supports riverbank stability will be retained where possible and the work will be carried out in a way that reduces disturbance to the river.”
Residents and river users may notice contractors working along sections of the river, along with temporary noise from equipment and short-term restrictions in some areas.
Mr Sheridan reminds the community to take care around work areas.
“Please keep a safe distance from crews, particularly when on or near the river and follow any signage or instructions on site.”
