We combined traditional and online methods to make sure we reached as many people as possible. We used an interactive map and online survey, held in person engagement (drop-in sessions, individual landowner meetings and stakeholder workshops), and hosted dedicated community and developer webinars.

We heard there was strong support for a regional, integrated approach to stormwater, however feedback reflected concerns about how the proposed infrastructure would affect private land and future development. We received feedback on:

• impacts to private property, particularly the perception of reduced developable land or fragmented lots due to proposed basin and channel locations

• land acquisition, including calls for clarity on timelines, compensation and whole-lot acquisition, where appropriate

• scheme design, particularly around basin placement, waterway location, catchment modelling and consistency with existing infrastructure and topography

• governance and coordination, with some concerns raised about alignment across government agencies

• timing and uncertainty, especially for landowners whose property is not expected to be serviced for many years.

Some stakeholders also highlighted the need for better clarity around planning overlays, watercourse mapping, and how changes to the plans would be communicated over time.

The key concerns raised during the public exhibition period can be broadly placed into ten categories.

• Impacts to private property
• Stormwater scheme design
• Land acquisition
• Policy and governance
• Stakeholder engagement
• Timing
• Environmental considerations
• Next steps for developing Developer Servicing Plans
• Land use and zoning
• Wellbeing

We thank the community, development industry and all stakeholders for taking the time to review the Aerotropolis Draft Integrated Stormwater Scheme Plans for Wianamatta Badgerys & Cosgroves and provide feedback.

As the Regional Stormwater Authority for the area and its waterways, Sydney Water must develop scheme plans that meet its responsibilities and align with the region’s future development.

Once the Aerotropolis Stormwater Scheme Plans for Wianamatta Badgerys and Cosgroves are finalised, they will be used to prepare Development Servicing Plans, which outline the costs and contribution requirements.

We understand there are many different concerns from landowners, the wider community and the development industry. We will keep working with other agencies to address specific issues raised, and we encourage people to contact the relevant agencies directly when Sydney Water is not the responsible authority.

Our Consultation outcomes report, includes recommendations made by the community and stakeholders, along with Sydney Water’s responses to each.
