Stormwater management plans for the City of Casey.
Council-ready Stormwater Management Plans for residential and mixed-use development across the Casey Planning Scheme. Peri-urban subdivision specialists; OSD-trigger commercial sites a regular workload.
Council requirements
What the Casey Planning Scheme requires.
The Casey Planning Scheme adopts the Victorian Planning Provisions with local schedules. Stormwater management is governed by Clause 56.07-4 for residential subdivisions and Clause 53.18 for non-subdivision development, both demonstrating compliance with EPA Publication 1739.1.
Casey applies a local OSD policy that frequently triggers on multi-unit and commercial sites — the council considers existing pipe capacity in the relevant catchment when assessing the need for on-site detention. Subdivisions in the south-east growth corridor sit within Melbourne Water drainage schemes and trigger Clause 66.04 referral.

SWMP service and quote inputs → Local context
South-east peri-urban subdivision and mixed-use commercial.
Casey covers a broad spread of development types — established suburbs in Narre Warren and Berwick, active subdivision in Clyde and Cranbourne East, and a growing commercial and mixed-use footprint across the municipality. Each site type carries different stormwater triggers.
For commercial and multi-unit projects in the established suburbs, the local OSD policy is the most common trigger we see. For greenfield subdivisions, Melbourne Water referral and STORM ≥100% are the binding constraints. The treatment-train pathway is covered in the Victorian WSUD guide.
