Frequently Asked Questions
Your Civil & Stormwater Questions Answered
Get clear answers to common civil and stormwater questions, helping you understand requirements, approvals and design expectations so your project progresses smoothly, compliantly and with confidence from start to finish.
Do I need a stormwater plan for my DA or CDC application?
Yes. Most councils require a compliant stormwater management plan. Often including OSD, drainage layouts, and flow calculations, before approving DA or CDC submissions.
How long does civil or stormwater design usually take?
Timeframes vary by project complexity, but most residential designs are completed within 3–7 business days. Larger commercial or civil projects may require additional time.
Can you assess flooding, overland flow and site drainage issues?
Yes. We conduct overland flow assessments, analyse flood impacts, and recommend drainage or OSD solutions to manage runoff safely and compliantly.
What information do you need to start the design?
Site survey, architectural plans, soil information (if available), council guidelines and any hydraulics or flooding data. We can advise you on exactly what’s required.
Can you work with my builder or architect?
Definitely. We coordinate directly with builders, architects and certifiers to ensure the design integrates smoothly with construction and approval requirements.
