Stormwater management plans for the City of Boroondara.
Council-ready Stormwater Management Plans for townhouse and multi-unit development across the Boroondara Planning Scheme — Clause 53.18 responses, on-site detention documentation, and flood overlay coordination.
Council requirements
What the Boroondara Planning Scheme requires.
Boroondara requires a stormwater management plan with all residential development of two or more dwellings on a lot, responding to Clause 53.18 of the Victorian Planning Provisions. Performance is typically demonstrated with Melbourne Water's STORM calculator or MUSIC modelling, and larger projects — residential buildings of four or more storeys, or non-residential development of 100 m² or more — also carry an ESD report with a BESS assessment.
Where council requires on-site detention, the storage volume and the permissible site discharge are confirmed by council's drainage team, with the system designed to AS/NZS 3500.3 and connected at the Legal Point of Discharge. Above-ground rainwater tanks cannot be used as the detention system. The treatment measures behind the STORM score are covered in the Victorian WSUD guide.

Service detail → Local context
Infill development on an established drainage network.
Boroondara's applications are overwhelmingly infill — townhouses and multi-unit projects on established lots in suburbs like Camberwell, Kew, Hawthorn, and Balwyn. The stormwater questions turn on the existing network: the Legal Point of Discharge, easement constraints, and the detention council requires where hard surface area increases.
Parts of the municipality also sit under flood overlays — the Special Building Overlay for stormwater flood risk and the Land Subject to Inundation Overlay for watercourse flood risk. On those sites, permit applications need Melbourne Water's consent, and finished floor levels are set above the identified flood level with 300 mm freeboard. When Melbourne Water gets involved is worth confirming before the application is lodged.
