Civil & Stormwater Engineers Gilead
Gilead is where the Greater Macarthur Growth Area meets some of the most environmentally sensitive development conditions in south-west Sydney. Home to Lendlease’s Figtree Hill community – the first stage of a development front planned to deliver thousands of homes between the Georges and Nepean rivers – this Campbelltown LGA suburb combines new-estate construction with serious expectations around waterways, erosion control and conservation corridors. Contrive Consultants provides stormwater drainage plans, on-site detention (OSD) design and environmentally responsive civil documentation for builders working in Gilead.
Building in Gilead
Gilead lies along Appin Road south of Campbelltown, on the ridge country between the Georges River to the east and the Nepean River to the west. The area was drawn into the Greater Macarthur Growth Area, declared in 2018, and Lendlease’s Figtree Hill – approved in 2019 for around 1,700 homes – is now under construction, with a further Gilead stage planned to add several thousand more dwellings over the coming decade.
What sets Gilead apart from other growth fronts is the ecological overlay. The master plan incorporates east-west conservation corridors along Menangle Creek and Woodhouse Creek, designed to keep koalas and other wildlife moving safely between the Georges and Nepean river systems, with large areas of surrounding land dedicated to conservation. For construction, that translates into genuine scrutiny of anything that could send sediment, uncontrolled runoff or pollutants toward the creeks – from the subdivision scale right down to a single house site.
The terrain is also a factor. Ridge and upper-slope lots step down toward creek lines, so builders encounter cross-fall lots, benched platforms and stormwater strategies that must respect both gravity and riparian setbacks. Campbelltown City Council assesses work here under its development controls and engineering specifications, layered with the precinct-specific requirements that come with a master-planned growth area.
What Gilead builders need
- Stormwater drainage plans – lot-scale designs connecting into Figtree Hill’s estate drainage at the correct legal point of discharge, prepared for DA or CDC lodgement.
- On-site detention – where required beyond the estate’s precinct-level basins, OSD design with documented storage, outlet and overflow provisions; we confirm what the estate infrastructure already covers before designing.
- Erosion and sediment control plans – done properly, not as an afterthought. Proximity to conservation corridors and creek systems means certifiers and council expect real controls: staged disturbance, sediment fencing, stabilised access and dewatering measures suited to sloping ground.
- Sloping-lot civil design – cut and fill plans, retaining coordination, driveway grades and overland flow management for lots with meaningful cross-fall.
- WSUD documentation – water quality measures where the approval requires them, consistent with the catchment-protective intent of the precinct planning.
- Waste management plans – construction waste documentation as part of the DA package, handled in-house.

Frequently asked questions – Gilead
Is Gilead in Campbelltown or Camden LGA?
Gilead is within the City of Campbelltown local government area, in the Greater Macarthur Growth Area. Applications are assessed by Campbelltown City Council or by private certifiers for complying development. Our plans are prepared to Campbelltown’s engineering requirements, which differ in detail from the Camden and Wollondilly councils nearby.
Why is erosion and sediment control such a focus in Gilead?
Because the precinct was planned around protecting Menangle Creek, Woodhouse Creek and the broader corridors linking the Georges and Nepean rivers. Sediment leaving a building site does not just risk a fine – it undermines the environmental commitments the whole development front was approved on, and enforcement reflects that. A properly designed and maintained sediment control setup is inexpensive insurance.
My Figtree Hill lot slopes toward a rear reserve. Can I drain into it?
Not by default. Discharge to reserves, riparian land or conservation areas requires the arrangement the subdivision actually created – typically an interallotment easement or a designated connection point – and unauthorised discharge toward creek corridors is treated seriously. We review your lot’s deposited plan and estate drainage design, then document the compliant solution.
