Millars Landing

Millars Landing is a 1,500 lot project in North Baldivis, which includes high groundwater, clay ground conditions, a conservation category wetland, direct connections to the Peel Main Drain, tree retention considerations and significantly varying boundary interface issues including the Kwinana Freeway, all of which have needed to be balanced to achieve a satisfactory outcome for all parties.

Initial stages at Millars Landing have been delivered as a non-front development and as a result, have required significant headworks infrastructure to be extended to the site boundary and also constructed within the project including the water distribution mains and a waste water pump station. The offsite works included a DBNGP crossing, varying services alignments to ensure tree protection and coordinated installation with other developers. The Baldivis Road roundabout and deep gravity sewer extensions including significant acid sulfate soil and dewatering management were also required with the works.

Given the constraining drainage issues, an ‘off-line’ drainage system was modelled and constructed to ensure allowable discharge rates for stormwater offsite are not exceeded. A sub-soil drainage design and overall water sensitive approach has minimized inundation areas significantly in POS areas.

The project also interfaces with Main Roads reserve for future widening along with Kwinana Freeway, with the associated noise attenuation requirements incorporated into the civil works designs.

The Stage 1A construction contract which was administered by TABEC, was achieved within an exceptionally tight time frame to meet project objectives and relied on negotiated outcomes and a close working relationship with City of Rockingham and the service authorities.
