Crace Water Sensitive Urban Design
Land Development Agency
Crace, Australian Capital Territory, Australia
Australia's first suburb to achieve GreenSmart accreditation in recognition of its sustainability initiatives
Crace Stage 2 was the first suburb in Australia to achieve GreenSmart accreditation in recognition of its sustainability initiatives, including cutting-edge water sensitive urban design by Calibre Built Environment.
Our team conducted an initial flood Investigation of the Crace catchment to determine attenuation requirements for storm events up to the 100-year Average Recurrence Interval.
Our solution was to devise a flood mitigation and stormwater quality strategy involving combined raingardens and detention basins. The raingardens not only allow for water treatment to be decentralised, but also provide high aesthetic value.
Additional water quality and quantity measures include gross pollutant traps, bioretention basins and swales.
