Stream health in full flow

Restoring waterways is a very satisfying part of the Boffa Miskell practice.

“We’ve seen emphatic support from clients and contractors, who have taken pride in these streams as they have unfolded,” says landscape architect Mark Lewis, “but the best part is seeing community members enjoy and embrace these enhanced environments.”

The implementation of these waterway projects is an all-encompassing design process, involving our ecologists, urban designers, and landscape architects, and working closely with engineers.

In recent years, bioengineering has increasingly replaced hard engineering, to create stable and functioning ecosystems based on natural stream morphologies. This design approach is carried through to construction where innovative construction methods often require Boffa Miskell ecologists and landscape architects to be on-site and work closely with contractors.

Three examples of these types of projects are featured here.

La Rosa stream ‘daylighting’

Liberating parts of the Avondale and Parahiku Streams from underground pipes at La Rosa Gardens Reserve in Green Bay was Auckland’s first dedicated stream daylighting project.

Oakley Creek restoration

Oakley Creek Te Auaunga in west Auckland has been realigned and restored for over a kilometre as part of Transit New Zealand’s State Highway 20 Waterview Connection construction project.

Duck Creek re-creation

Duck Creek in Whitby, Wellington, has been shifted 50 metres sideways over a length of 1km to make way for a Todd Property Group subdivision. The consent conditions required that the stream look and perform as a natural waterway, with improved Stream Ecological Values (SEV).
