CKL conducted the preliminary and detailed stormwater management design for the upgrade of the Auckland Botanic Gardens car park and access ways. Close liaison with Council and operational staff at the Botanic Gardens was the key to the integration of existing and proposed stormwater treatment and management systems. The stormwater management upgrade included the treatment of runoff through a raingarden, prior to discharge to a stream. This raingarden treatment has been successful and is now showcased by both Council and environmental consultants as to ‘how a raingarden should be designed’.
