Keeping BOP flood defences functioning With increased rainfall and weather events impacting the region, Bay of Plenty Regional Council is reminding landowners living near the region’s flood defences to refresh themselves of the rules.
The Flood Protection and Drainage Bylaws provide protection from damage and misuse to flood protection and drainage infrastructure assets (such as stopbanks, floodgates, drains and pump stations), which are managed by or under the control of Regional Council. “Flood defences are the first line of defence when it comes to reducing the impact of significant flooding,” says rivers and drainage asset manager Kirsty Brown. “They have been built to increase productivity of land, and prevent damage, danger, and distress to the community from flooding, and problems associated with a lack of drainage, so it is crucial they function properly when needed.” Kirsty says a common issue is stock overgrazing or pugging on stopbanks during periods of prolonged rainfall, as this can damage and weaken the stopbank. “While light grazing of sheep and cows is allowed on stopbanks, it is not permissible to allow stock to damage them, and most farmers and lifestyle block owners know these rules.
“The reason is that when stopbanks become wet, stock can churn up the ground. This can create integrity risks for the stopbank through loss of grass cover – good grass cover is needed as it helps hold together the soil structure underneath. Loss of grass cover has been shown to be a contributing factor to stopbank failure in the past.” Another issue is dumping rubbish on stopbanks or in drains, which can end up blocking the drain’s pump station and stop it from working effectively. “Pumps are important for removing water out of drains as they become full, so if there was heavy rainfall and the pump wasn’t working, water levels in the drain would rise and potentially overflow, putting land and lives at risk.” Under the bylaws, these are not permitted activity and landowners can be liable for any damage to the flood defences. “Our Rivers and Drainage team routinely monitor the condition of our flood defences, but we also welcome contact from members of the public who may suspect a problem. Our 24/7

An environmental answer to slash A unique multi-purpose shredder, imported from Germany, is dealing to slash and stumps and enabling it to be added back into the earth to enhance the environment.
The shredder is being used instead of burning or creating debris, which can cause problems and take years to break down. Ernie and Heidi Schicker formed Schicker Earthmoving Contractors more than 35 years ago. Over the years the partnership has transitioned from farm fencing (Ernie winning the National Fieldays Golden Pliers fencing competition three times) to earthmoving (bulldozing fence lines, tracks, raceways, subdivisions, house sites) and now recycling a variety of materials. “Initially we bought the shredder to recycle our pine plantation and found it does a fantastic job. It is so diverse, from crushing rock – up to 150 tonne an hour – to crushing concrete and removing reinforcing steel from it as well as shredding tyres,” says Ernie Schicker. “One person operates the shredder
The shredder makes quick work of slash and stumps to clear the environment. from a loader or digger that loads the material and the remotely controlled Arjes Impaktor 250 shredder does the rest. “The shredder was so effective at transforming our forestry block into pasture that we bought a second one to fulfil demand around the North Island.
“Our shredders are available for dry hire or with an operator or digger across the North Island.” For further information, see their advert on this page.
