stormwater harvesting and landscape integration project
Birrarung Marr, is a relatively new 8ha city park on the Yarra River’s north bank next to Federation Square. Opened in 2002, the park suffered from the millennium drought that lasted in Melbourne until 2010. Following the ten-year review of the park by Jones and Whitehead, Urban Initiatives were commissioned to integrate a stormwater harvesting system with the site’s upper terrace landscape.
In collaboration with Ron Jones, CARDNO and Biofilta, Andrew Brophy worked on the integration of this large-scale infrastructure. The system captures, treats and stores for reuse, approximately 35 million litres of stormwater annually (runoff from 37 hectares of Melbourne’s CBD). It is a high output system (large volumes treated) that has a relatively small, well-designed surface footprint (100 sq. metres).
A renewed landscape sits above the 2.5 megalitre underground storage tank. The landscape features a 60 metre long formal terrace and seating, with an adjacent bio-filtration bed and extensive embankment plantings. The formal upper terrace plays out as promenade and viewing platform, offering commanding views of the city, river and gardens.
A staggered stairway adds a critical axis connecting the high ground of the park and the city at Exhibition Street to the riverside lower terrace. The stairway was conceived as a hillside escarpment where the staggered stairs are punctuated with terrace like outcrops, planted with dwarf Yellow Gums. The stairs include short run bike ramps that replace a goat track worn by cyclists, while the concrete terraces allow casual occupation of the hillside.
