The Little Stringybark Creek Environmental Significance Overlay (ESO) has been introduced into the Yarra Ranges Planning Scheme to improve the health and condition of Little Stringybark Creek in Mt Evelyn.

Under the ESO, a planning permit is required for any buildings or works that increase the hard surface (impervious surface) area within a property by more than 10m². For example, a proposal to extend an existing dwelling, construct a shed or garage, or construct a driveway on a site that creates more than 10m² of additional impervious surface, triggers a planning permit under the ESO.

In order to obtain a planning permit, you must demonstrate that stormwater runoff created by the additional impervious surfaces (e.g. roofs or paving) is treated to a minimum Stormwater Retention Score (SRS)  of 6 out of 10 (as standard specified by the ESO).  This score measures the level of stormwater treatment achieved and will be established as part of the application process.

In practice, meeting the ESO requirements means installing stormwater control measures such as rainwater tanks, raingardens, or infiltration trenches. Visit our options for treating stormwater page to find out more on stormwater treatment measures.

Application process

1.    Contact Yarra Ranges Shire Council to enquire about a planning permit application. Council will direct you to contact Melbourne Water to obtain ESO requirements.
2.    Complete the Stormwater Treatment Assessment application form and submit it to Melbourne Water. Include the required documentation (listed in the section below). Submit your application via the button at the top of this application page.
3.    Our Stormwater Treatment Assessor will contact you to make an appointment for a site visit to determine a viable stormwater treatment plan in order to meet the requirements of the ESO.
4.    We will consider the proposed development, based on the finalised stormwater treatment plan, and inform you of our decision.
5.    Submit our decision to Council, together with your planning permit application, to enable Council to assess your development.

Documents required

To help us offer relevant advice about the proposed development, you will need to supply the following information:

-    Completed Stormwater Treatment Assessment application form
-    Detailed development plans, including floor and elevation plans
-    Existing site plans
-    Previous letters or correspondence from us (optional)
-    Any supporting reports (optional)
-    Current title plan
-    Survey information

Duration

Our Stormwater Treatment Assessor will contact you within 10 business days of us receiving your application form, in order to schedule a site visit. Depending on your availability, the site visit, preparation of the Stormwater Treatment Plan and final approval should be completed within 10 days of the finalised Stormwater Treatment Plan being submitted.

Fees

There are no fees for this service.
