Croftfield Lane

  • Croftfield Lane

The original Croftfield Lane stormwater wetland was constructed as part of the development of the Wairau Industrial area. The wetland serves a total of 467ha of developed urban catchment, and was constructed in the 1980’s but de-commissioned in the mid 2000’s due to weed infestation problems.
In 2008 the former North Shore City Council identified an opportunity to re-develop this device in view of the need to re-establish its stormwater treatment functions and in recognition of aesthetic, recreational, visual and other potential benefits.
In collaboration with Boffa Miskell Ltd, AR & Associates was commissioned by Auckland Council in 2010 to initially undertake a detailed options assessment for the re-development of this facility, including a catchment wide hydrological analysis and hydraulic analysis to assess its performance, and subsequently the detailed design, costing and preparation of contract documentation which was completed in 2015.
The design resulted in an attractive, bespoke stormwater device that achieved water quality, quantity and gross pollutant removal functions, while offering an interconnected parklike area with art elements resulting in a significant amenity improvement to this busy commercial area.
The Croftfield Lane wetland is now under construction and programmed to be completed by the end of 2016.
