Have your say on our latest plans

As Regional Stormwater Authority, we’re committed to supporting delivery of regional stormwater infrastructure to service the Aerotropolis.

We are asking for feedback on the Aerotropolis Draft Integrated Stormwater Scheme Plans for Wianamatta Badgerys & Cosgroves areas. A third scheme for the Duncans Mulgoa area is still in development. The scheme plans show the proposed regional stormwater infrastructure required to service these areas.

Have your say

The draft scheme plans and supporting materials are available on this website, and you can provide your feedback from now until Monday 5 May 2025. The feedback we receive on the draft plans will be considered as we progress the designs for stormwater system.

After you've reviewed the draft plans, you can provide feedback by emailing us, or right here on our project page by:

  • dropping a pin and leaving a comment on our interactive map, which shows property level detail for the proposed regional stormwater infrastructure
  • completing a survey to tell us what you think.

If you're the owner of a property that is impacted by the proposed infrastructure, you can also schedule an individual briefing with our project team. We're sending these landowners a letter with details about how to do this, or you can email us or call us on 1800 645 466 (business hours) to find out more.

  • Your guide

    We've developed a summary document that explains the different elements of the Aerotropolis Draft Integrated Stormwater Schemes.

    If you'd like to know more about our plans and what they might mean for you, this is a great place to start.

  • Interactive map

    You can see the proposed infrastructure, right down to a property level, on the interactive map.

    You can also drop markers with your comments directly on the map.

  • Types of stormwater infrastructure

    We've developed explanations for the different types of stormwater infrastructure included in the scheme plans. You can learn more about each of these and how they work.
