The "unseen ecological heroes" of Quay Street's transformation
When the work to transform Quay Street between the Viaduct and Brtiomart is complete, there will be 50 new gardens along the water's edge - including 19 lush rain gardens and 200 new native trees as well as the 40 existing pōhutukawa trees (which have been relocated to Teal Park during construction).
While the gardens will add to the green edge of the city, providing shade and shelter to the people in Quay Street, it’s the unseen work below the surface of the rain gardens which provides real environmental benefits.
Auckland Transport's Downtown Programme Director Eric van Essen says “rain gardens are an unseen ecological hero”.
“A rain garden is a sustainable and economical way of dealing with storm water as nature intended. Not only do they help remove pollutants and slow down stormwater flows they recharge freshwater bodies and look attractive.
“Rain gardens also filter storm water through soil mix and plants which absorb and filter contaminants before it flows to surrounding ground, pipes, drains and streams, and eventually to the sea.”
