Water Sensitive Urban Design (Stormwater Management)

A planning permit is usually issued subject to standard water sensitive urban design (WSUD) permit conditions depending on the development types and scale.

The permit holder is required to submit the documents in accordance with the following WSUD permit conditions and our standard WSUD plan notations.

Standard WSUD permit conditions

Amended STORM assessment condition

An amended STORM assessment report must be submitted simultaneously with the submission of amended plans in accordance with Condition 1. The STORM assessment must obtain a minimum 100% to comply with Clause 22.03-4 (Stormwater Management) of the Moonee Valley Planning Scheme.

WSUD design details condition

A minimum 30 days prior to any building or works commencing, all WSUD details (relating to the WSUD treatment measures nominated in the approved and complying STORM report), such as cross sections and/or specifications, to assess the technical effectiveness of the proposed stormwater treatment measures, must be submitted for approval by the Responsible Authority.

(Note:
In the event water tank is the only stormwater treatment measure nominated in the STORM assessment report, WSUD design details of the water tank are not required to be endorsed by Council. You are required to install the water tank(s) in accordance with the Australian Standards.)

WSUD site management plan

A minimum 30 days prior to any building or works commencing, a WSUD site management plan must be submitted to and approved by the Responsible Authority detailing the site and environmental management methods to be used.

The plan must include, but is not limited to:

a) A statement or report outlining all construction measures to be taken to prevent litter, sediments and pollution from entering the stormwater systems.

Once submitted and approved the works detailed by the WSUD site management plan must be carried out to the satisfaction of the Responsible Authority.

WSUD maintenance program condition

A maximum 30 days following completion of the development, a WSUD maintenance program must be submitted to and approved by the Responsible Authority which sets out future operational and maintenance arrangements for all WSUD measures. The program must include, but is not limited to:

a) inspection frequency.

b) cleanout procedures.

c) as installed design details/diagrams including a sketch of how the system operates.

d) a report confirming completion and commissioning of all WSUD response treatment measures written by the author of the WSUD response and STORM or MUSIC model approved pursuant to this permit, or licensed installing/commissioning plumber, or similarly qualified person or company. This report must be to the satisfaction of the Responsible Authority and must confirm that all WSUD treatment measures specified in the WSUD Response and STORM or MUSIC model have been completed and implemented in accordance with the approved report.

The WSUD maintenance program may form part of a broader maintenance program that covers other aspects of maintenance such as a builder’s guide or a building maintenance guide.

Construction and site management plan

A minimum 30 days prior to any building or works commencing, a Construction and Site Management Plan (CSMP) must be submitted to and be approved by the Responsible Authority detailing the construction activity proposed and the site and environmental management methods to be used. The CSMP must be in accordance with our CSMP’s guideline and templates.

When approved, the CSMP will be endorsed and will form part of this permit.

The development must be carried out in accordance with the endorsed CSMP and the provisions, requirements and recommendations of the endorsed CSMP must be implemented and complied with to the satisfaction of the Responsible Authority.

Generic WSUD notes on drawings

We require the following generic WSUD notes to be provided on all relevant drawings inclusive of ground floor plan, roof plan and landscape plan.

Rainwater tanks

To each rainwater tank provide a note equivalent to “The rainwater from Dwelling x roof catchment area of x m2 is to be collected and discharged via a mechanically pumped OR fully charged OR gravity fed system (applicant to select type of system) into a x Litre capacity rainwater tank which is to be connected to all toilets for toilet flushing”.

"If the Rain Water Tank is to be connected to the laundry cold water tap/washing machine as well as the toilets then the note should read as follows: “The rainwater from Dwelling X roof catchment area of Xm2 is to be collected and discharged via a mechanically pumped OR fully charged OR gravity fed system (applicant to select type of system) into a X Litre capacity rainwater tank which is to be connected to ALL toilets for toilet flushing and the laundry cold water tap/washing machine”.

Raingardens

Provide a note equivalent to “The rainwater from dwelling X roof area of Xm2 OR impervious paved area of Xm2 (select applicable) to be collected and discharged via a mechanically pumped OR fully charged OR gravity fed system (applicant to select system) into a Xm2 100 (or 300)mm raingarden, raingarden to be fully lined with an impervious liner and have its overflow and aggie drain connected to the LPOD”.

Buffer strip or in-ground raingarden

Provide a note equivalent to “The rainwater from the impervious paved area of Xm2 to be collected and discharged into a Xm2 buffer strip or in-ground raingarden, to be fully lined with an impervious liner and have its overflow/aggie drain connected to the LPOD”.

Paving

Provide details of the location and type of all paved areas (both WSUD treated & untreated areas). On drawings note if pervious (permeable) or impervious (impermeable), dimension and provide areas in m2, and show grade and connection to WSUD treatment measure if treated.
