This residential development in North Lakelands, Mandurah will ultimately create 1,900 lots across 23 stages.
To date 5 stages have been bulk earthworked with 3 of those being progressed to completed titled lots and a road connection to Mandurah Road provided.
The site is at the northern extent of the Gordon Road sewer catchment area. Design of trunk sewer needed to ensure future development to the west could access sewer and the route selection for the main was based on ensuring minimal change in design lot levels to service the whole site by gravity mains.
Ocean Hill Estate is located on the eastern side of Mandurah Road which will ultimately become six lanes. Traffic modelling of two proposed major intersections was undertaken and designs developed which accommodated the ultimate road widening and connection of additional legs from future development of land on the western side. The design ensured correct geometry and capacity for the intersections to function adequately in both the short and long term.
The bulk earthworks strategy was to ensure a cut to fill balance over the entire development to minimise importation and exportation of sand material to benefit the development's budget and schedule.
The site was previously a limestone quarry with very little remnant vegetation. Where possible Public Open Space was positioned in areas with large trees and design of drainage sumps and surrounding roads done to ensure the majority of these trees could be retained.
