Florence Estate is an 85-hectare residential development in Mandogalup within Perth’s expanding south-west corridor, around 24 km south of the Perth CBD. The estate delivers a mix of low and medium density housing supported by civil infrastructure and water and utility networks.

Peritas provided civil engineering design for the estate, delivering integrated infrastructure and sustainable drainage solutions in close coordination with key stakeholders, including the City of Kwinana and Water Corporation. A central focus of the project was refining the water sensitive urban design approach to achieve greater at-source stormwater management and improved streetscape outcomes. Working with hydraulic consultants, planners and authorities, Peritas developed a drainage strategy incorporating rain gardens, swales and reduced piped infrastructure, delivering a cost-effective, sustainable solution that reduces downstream flood risk and enhances community amenity.
