Diversi Consulting were engaged by Rawson Homes to undertake the engineering design of a 66 lot residential subdivision on a 4.5ha site at North Kellyville.
The works included bulk earthworks, roads, stormwater drainage, bio retention basin/swales, utility services (electrical, street lighting, gas, telecommunications, water and sewer), lines/ signage as well as retaining walls.
Given the steep-sloping land, it was necessary to bench parts of the site and install retaining walls.
As the site was also located near Caddies Creek, it was important to control stormwater runoff and quality. As such, Diversi proposed a combined sediment, detention and water quality basin to control the creek and habitat adjacent to the site.
