The proposed Twin Waters West masterplan is designed to contribute to the existing enviable Sunshine Coast North Shore lifestyle.
The proposed masterplan features a large, new lake. The lake will be around 17.4ha in size and provide water amenity with walkable waterfront.
The lake will receive pumped water from a connection to the Twin Waters lake. A weir will be created and maintained between the two communities to manage water levels. The water will be delivered into the Twin Waters West lake by an underground pump.
The new lake at Twin Waters West will be maintained at a relatively low depth to receive stormwater during high rainfall events. This large onsite storage capacity will help the new community achieve very high resilience to local flooding.
The water in the lake will normally be recharged every month. Water will gradually release to the Maroochy River through an underground pipe, as new water is pumped into the lake from the Twin Waters canals. This dynamic motion won’t be noticeable but helps ensure good water quality in the new lake. Recreation such as kayaking is proposed within the new lake.

The proposed masterplan features extensive natural spaces, parks and open space for recreation and to provide additional habitat and connections for fauna and flora. The combination of the onsite lake and natural space is over 50% of the site.
The existing onsite central wetland will be retained, protected, and enhanced as a feature of the new community, with a dedicated kangaroo reserve. A minimum 50m buffer between the central wetland and new lake is proposed to protect the wetland from salt water.
Three destination parks are proposed including: the protection and enhancement of Settlers Park, creation of a new lake front park, large recreation park incorporated and kangaroo refuge area.
Stockland is proposing a high standard of landscaping, referencing the quality of landscaping at Twin Waters.

Protecting the character, standard and amenity of the existing North Shore housing, lot sizes averaging 700m2 are proposed within the Development Application to reflect the existing low density character of Twin Waters. Privacy for Twin Waters is maintained through retention of a thick vegetation buffers between the two sites.
The design of the new community will help ensure there are no increased flooding impacts for surrounding homes.
New, high quality, sustainable homes will be a central component to a future sustainability strategy. High sustainability standards will be underpinned by selection of building materials and insulation, along with water and electricity efficiency.
We are able to control the quality and sustainability of homes through the selection of leading builder partners who will apply a future Twin Waters West building covenant.
Reflecting the active Sunshine Coast lifestyle, the masterplan proposes a safe and convenient 2km* active transport network through the site. This includes 650m of walkable waterfront along the lake edge. Image to be supplied. The pathways will connect parks, large areas of open space for recreation, the coastal pathway and connections to other surrounding areas. The primary road through the new community will include cycling lanes and built to standards to support potential future potential bus services.
A Development Application has been lodged with Sunshine Coast Council to seek approval to deliver a premium lake based community of in keeping with the character of the adjoining Twin Waters community.
The proposed masterplan and development application includes low residential density lots, protection of the onsite wetland and provides resilience to flooding for new residents and the residential communities surrounding the site.
The proposed development has been designed to meet stringent State and Local Government guidelines to ensure that there is no net worsening of flooding as a consequence of the proposed application. Extensive modelling has occurred through both the rezoning that was approved by the State Government and Sunshine Coast Council and in the preparation of the current development application including extensive peer reviews.

Flooding resilience is achieved by a combination of factors.
The site will be filled to raise the ground and lot levels. This will most likely achieve flooding resilience to the AEP 1% (formerly called 1:100-year event) + climate change to 2100 + an additional 0.5m. During major rainfall events these heights will help to protect the new community, in addition to other measures.
The large, deep lake (17ha) can contain, secure and slowly discharge large volumes of in-flowing stormwater during high rainfall.
During normal day to day operations the lake will be maintained at a much lower level (0.6 AHD) than the filled heights (3.45m to 5.4m AHD) of the developable area to be able to provide capacity to receive and contain high volumes of stormwater.
The stormwater systems will be designed to carry water inwards within the site and towards the new lake and not towards the existing Twin Waters community or other homes outside of the site.
A similar approach is applied on this site, as Twin Waters, which has achieved flood resilience since the 1990s. The same designer, Dr Trevor Johnson, is informing the hydrology system for this site.

Yes. Average lot sizes are least 700m2. The smallest lot is 500m2. This is the same as Twin Waters and complies with the Planning Scheme.
Stockland is proposing significant protections and enhancement of the onsite remnant wetland.
Proposed protections include a 50 metre minimum natural space buffer from the onsite lake to the wetland. A network of bioretention basins are proposed to be linked to stormwater systems to direct stormwater into the wetland.
In addition, a solid barrier is proposed to be constructed inside the perimeter of the new lake. This is expected to significantly restrict the movement of saline water from the onsite lake towards the wetland, which relies on freshwater.
Enhancements will likely include reduction of weeds and pests within the wetland. Stockland is also working with leading ecologists to ascertain other enhancements to create habitat for more species such as introducing hollows and ‘hides’ for species. No buildings are proposed within the extended wetland area.

Stockland recognises Kangaroos are an enduring feature of the Twin Waters lifestyle and appeal. The proposed masterplan can help to sustain local kangaroos by:
The proposed 2023 masterplan includes many significant changes compared with the previous proposal. These changes include, but are not limited to:
A new entry road is proposed from the David Low Way into Twin Waters West and a new signalised intersection is proposed to replace the T-intersection at Ocean Drive and the David Low Way.
This diagram indicates the proposed lanes, signalised arrangements, and movements. This is subject to approval.
