Common in West Lakes
What earthworks & drainage work has to deal with here
01
Sand fill that needs compaction
Dredged sand fill drains instantly but must be compacted and edge-restrained under paving and turf.
What West Lakes is built on
Dredged sand fill from the lake's construction — deep, uniform and hungry for compaction.
Sand drains quickly until it meets clay or a water table below. Drainage design checks what is beneath the sand before relying on soakage.
Building in West Lakes
West Lakes was engineered into existence in the 1970s — the lake dredged, the land raised on sand fill — and every outdoor project inherits that origin story. The sand base is uniform and drains instantly, but it needs methodical compaction and edge restraint under any paved or turfed surface. Waterfront owners renovate to the water: terraces, glass-fenced edges and alfresco rooms oriented to the lake rather than the street. Reserve-backed and lake-edge boundaries come with council interface rules worth understanding before designing. Salt and humidity off the water quietly select the fixings list.
Our approach in West Lakes starts with a level survey of where water enters, stalls and can legally leave. Connections to the legal point of discharge meet City of Charles Sturt requirements, and surfaces are reinstated over trench lines.
Rainfall (Dry coastal strip): roughly 440–480 mm a year (approximate long-term averages at nearby Bureau of Meteorology stations). Sea breezes and sandy soil dry gardens out fast, so drip lines under mulch and salt-tolerant planting do more than extra watering.
