We're reducing flood risk to properties and restoring local creeks and waterways.

 About Northwest Sydney Land & Waterways

We own stormwater or 'trunk drainage' land in Northwest Sydney in what is known as the 'Rouse Hill development area'. Trunk drainage land is low lying land that's prone to flash flooding. This land may look like creeks, bushland or parks and reserves, with stormwater pits or concrete channels in the middle. Housing developments are often built near creeks and trunk drainage land.

We regularly maintain and rehabilitate local creeks and bushland in this area by planting local native plants and removing weeds and invasive species.

We make sure the land is well looked after to reduce flood risk to properties, restore local creeks and waterways and improve the quality of water entering the Hawkesbury-Nepean River.

Each year we remove around 375 cubic metres of rubbish and 510 tonnes of sediment from trunk drainage land in the Rouse Development Area.

We've also prepared master plans for certain areas of land and waterways, including for parts of Caddies Creek, Strangers Creek and Smalls Creek in Kellyville and Beaumont Hills.

Strangers Creek

We're revitalising part of Strangers Creek in Kellyville because it's been through a lot of urban development since the 1990s. The project involves rehabilitating the creek banks and establishing fauna habitat to help restore the natural environment and character of the creek. Work started in 2017 and will finish around the end of 2018.

Elizabeth Macarthur Creek

We're looking at revitalising part of Elizabeth Macarthur Creek in Kellyville to protect the flood prone land, rehabilitate the creek and protect the environment. We'll let the community know when this project is due to start. 

Caddies Creek and Strangers Creek Landscape Master Plan

The Master plan explains how the area will be used and managed in the future. It shows flood plain management, environment and indigenous heritage protection for example. 

The plan also makes sure that the recreation and social aspects of these areas are protected. It supports The Hills Shire Council’s proposal to provide a new sports complex for the local community.

Council has completed detailed planning and anticipates the sporting fields will be ready by the 2018-19 summer season.

Smalls Creek Landscape Master Plan

The Master plan was finalised in 2013 to protect ecological, scenic amenity and recreational values of the land. It outlines how we'll manage things like flooding, water quality, protected species, indigenous heritage, public safety and bushfires.

Other land and waterways projects in the Rouse Hill area

We're investigating other waterways and land that we own in Rouse Hill to see if they would benefit from specific master plans. These areas have complex issues and land uses.

As our investigations progress, we'll keep the community informed and involved in the consultation process.

How can you prevent weeds growing in bushland?

  • Choose native plants where you can as exotics can spread and overrun native bushland.
  • Don’t dump garden waste or lawn clippings in bushland. They contain seeds that damage native bushland and waterways.
  • Don’t damage plants or wildlife in bushland. This includes mowing grass and removing plants.
  • Don’t dump rubbish or building materials in bushland, creeks or stormwater channels.

Report any rubbish or building material by calling:
