I’m really digging this! T+T caught this little sweetie in action at the Drury South Crossing open day.

Nature at the heart of Auckland’s largest industrial subdivision

Lush wetlands, meandering streams, reserves, parks, walkways and cycle ways will form the heart of South Auckland’s Drury South Crossing development.

The 361 hectare development, rezoned as part of the Auckland Unitary Plan, includes a 178ha industrial subdivision and a 42ha residential subdivision that will provide workers and residents alike with fantastic opportunities to take time out to relax and explore.

T+T’s Peter Norfolk, Design Manager and an integral member of a dedicated and innovative project management team, is relishing the challenges that come with helping to create Auckland’s largest industrial subdivision for our client Drury South Ltd., a subsidiary of longstanding mining, quarrying and concrete manufacturing company, Stevensons Group.

“It’s full on – a great challenge. T+T are the lead consultants and we have a good, big, dedicated team.”

What’s more, what was little more than farmland will soon be an awesome new space providing a large, state of the art industrial area balanced with extensive environmental enhancement and green space - a “lovely environment”, Peter says.

T+T is providing civil engineering design for all the industrial areas, including all buried services, three waters infrastructure, roading design and floodplain/streamworks design. The challenges posed by such a large floodplain and its shallow gradients have brought T+T’s exceptional thinking to the fore.

“In terms of stormwater, we had to be innovative in how we manage overland flows. While we’re using piped infrastructure, we’re also maximising the road corridors to carry flows,” Peter explains.

“We’ve designed road cross sections so that the depths and flows are safe and where we don’t have roads, we’ve used a combination of pipes and channels to optimise flows so water doesn’t enter buildings.”

The green space at the heart of Drury South Crossing will function as a residual floodplain, but with a difference. Workers and residents will be able to stroll, run and pedal their way across hectares of parkland, stopping to take in the wildlife inhabiting the area’s meandering streams and wetlands. All of this has been designed with invaluable input from local iwi, Ngāti Tamaoho.

The subdivision is designed to cope with a 100-year flood event, so when Mother Nature unleashes her worst, extremely large flows of water will spill overland to benefit the wetlands and wildlife, which include at-risk short-fin and long-fin eels, as well as other species of native fish.

Landscape architects Boffa Miskell are responsible for the creation of an abundant, naturalised environment, featuring native New Zealand plantings ranging from flaxes and grasses, to hectares of forest.

Work on Drury South Crossing began in 2016 and it’s expected that the staged development will span several years. Featuring a mix of heavy and light industry, and a commercial area, it is in an outstanding position to access all the major North Island markets. Adjacent to two, State Highway 1 interchanges, it’s just 30 minutes from Auckland city, just over an hour from Hamilton and just over two hours from Tauranga.
