24-lot subdivision, City of Whittlesea — STORM 108%.
Greenfield subdivision in the Whittlesea Planning Scheme, inside a Melbourne Water drainage scheme. SWMP, MUSIC modelling, and Melbourne Water referral coordinated end-to-end — cleared at first submission.
Site, scope, and the binding compliance pathway.
SWMP, MUSIC modelling, and Melbourne Water referral.
The site was a 24-lot residential subdivision in the Whittlesea growth corridor, sitting inside a Melbourne Water drainage scheme. Clause 56.07-4 of the Victorian Planning Provisions applied; Clause 66.04 referral to Melbourne Water was triggered.
We prepared a full Stormwater Management Plan including detailed MUSIC modelling against the EPA Publication 1739.1 pollutant load reduction targets (80% TSS, 45% TP, 45% TN). The treatment train integrated lot-scale rainwater tanks with an estate-scale bioretention basin sized to coordinate with the broader Melbourne Water scheme drainage logic.
We coordinated the Melbourne Water referral end-to-end — pre-referral consultation, formal referral submission, and response packaging. The referral cleared at first submission with no request for further information.
First-submission clearance, scheme-coordinated treatment.
- STORM score of 108%, exceeding the EPA Publication 1739.1 best-practice target.
- MUSIC modelling confirmed 82% TSS, 47% TP, 46% TN pollutant load reduction.
- Melbourne Water referral cleared at first submission — no request for further information.
- Treatment train coordinated with the broader scheme drainage, including downstream wetland integration.
- CAD-compatible details supplied to the project engineer for civil design without rework.
