Performing engineering feasibility studies across a range of disciplines for a new residential subdivision

Willowdale Residential Development, East Leppington

Located in one of Sydney’s major growth corridors, the Willowdale residential development in the East Leppington Precinct showcases how we help our clients balance environmentally sustainable outcomes, social needs, and economically feasible development. Willowdale is a master planned community delivering 3,700 residential lots, a village center, parks and open space, environmental corridors, schools, retirement living precinct, and a retail center—setting a new benchmark for urban development in the region.

Our teams carried out engineering feasibility assessments, survey, flood modeling, traffic modeling, water and sewer design, bridge design, and all other civil engineering design works, from inception through to completion. This was a project with a significant scope, not only in its extent but over a long delivery schedule. It required balancing numerous constraints, including interfaces with major roads and other infrastructure servicing the area.

We were mindful about protecting existing native vegetation—including a portion of Cumberland Plain Woodland and a threatened species—while also managing stormwater treatment and flood conveyance within these sensitive areas.
