If you’re planning a renovation, extension, or new build in the Sutherland Shire, one question often comes up: “Do I need a structural or civil engineer for stormwater design?”
The short answer: Yes (for most projects that affect drainage, runoff, or compliance with council regulations)
Why Stormwater Design Matters
Stormwater management is not just about avoiding puddles. Poor drainage can cause:
- Flooding around your home
- Soil erosion and property damage
- Damage to retaining walls or landscaping
- Council compliance issues
A properly engineered stormwater solution ensures your property is safe, compliant, and sustainable.
When a Structural/Civil Engineer Is Required
In Sutherland Shire, an engineer is generally required for:
- New builds or extensions that increase impervious surfaces
- Alterations affecting natural drainage patterns
- Subdivisions or major landscaping works
- Projects requiring council approval for stormwater detention or connection
A qualified stormwater engineer in Sutherland Shire ensures your project meets Sutherland Shire Council requirements and Australian Standards for stormwater design, including:
- AS/NZS 3500.3: Plumbing and drainage – Stormwater drainage
- BCA/NCC requirements
- Local council development control plans (DCPs)
