Urban rivers and catchments program

This project delivers targeted erosion protection and bank stabilisation works across priority urban waterways in the Shoalhaven region. By addressing sedimentation and water quality issues, the initiative provides immediate mitigation of erosion risks and reduces potential environmental damage.

Key components include:

• Bank stabilisation and erosion control to improve water quality.
• Revegetation of degraded riparian zones, enhancing habitat for native and threatened species.
• Support for aquatic ecosystems through cleaner waterways and improved habitat connectivity.
• Community access improvements to natural areas, fostering engagement with local environments.

Together, these efforts contribute to healthier waterways, more resilient ecosystems, and a stronger connection between people and nature.

Bank stabilisation and feasibility and options assessment

Water Technology Pty Ltd (water, coastal and environmental consultants) was engaged by Shoalhaven City Council to prepare a Bank Stabilisation Feasibility and Options Assessment. The objective of the report was to i) assess the feasibility of bank treatment options and ii) develop concept designs of preferred treatment options for 6 high-risk sites identified as a priority in studies completed thus far in the development of the Lower Shoalhaven, Lake Conjola, St Georges Basin, Sussex Inlet, Swan Lake and Berara Creek Coastal Management Programs.

Study sites included the following locations

• Coorong Road, Shoalhaven River
• Mavromattes Reserve, Shoalhaven River
• Crookhaven Heads
• St Georges Basin
• Sussex Inlet
• Lake Conjola

Consultation on these works has been undertaken throughout the development of Council’s various Council’s Coastal Management Programs (CMPs). The CMPs have identified that works to improve the condition of sensitive areas in coastal environments provide an opportunity to reduce the risk of exposure to coastal hazards within these estuaries while also supporting local biodiversity.

Bushcare groups works with Shoalhaven Council Bushcare and Land Management staff to complete regeneration activities at five locations adjoining or containing creeks, estuaries and Intermittently Closed Open Lake and Lagoons (ICOLLS).

The below five sites were identified as priority locations for restoration following consultation with Bushcare volunteers and Council staff.

• Lake Wollumboola and Sheepwash Creek  
• Smiths Bay and Tallyan Point 
• Dyball Reserve 
• Callala Creek and Mitchell Road Reserve 

Restoration activities included weed removal, revegetation, access control as well as community engagement to support the regeneration and enhanced condition of mapped Threatened Ecological Communities (TEC) identified within the Shoalhaven.   

A total work area of 104 hectares was assessed and weed control was conducted in an 38 hectares of land, known to contain TECs. As part of the work, 850 tube stock were planted including 200 Grey Mangroves, with approximately 400 metres of exclusion fencing to protect revegetation works and close informal access tracks that have resulted in erosion and loss of vegetation.

Shoalhaven City Council is developing a strategy to enhance urban tree canopy and green cover across local parks, streets, and neighbourhoods. This initiative will deliver environmental benefits by improving the health and biodiversity of nearby waterways and riparian corridors. The strategy will take a holistic and integrated approach to urban greening, identifying opportunities to collaborate with local businesses and industries to support carbon neutrality and establish resilient local vegetation communities

This work is supported by the Urban Rivers and Catchments Program, which aims to build environmental resilience in a warming climate. By increasing green cover, the strategy will help reduce urban heat, improve water quality, and create healthier habitats for native wildlife. It also contributes to public health and wellbeing by making natural spaces more accessible and enjoyable for the community.

As a first step Council is undertaking a Baseline Canopy Study that will provide the foundational data and analysis tools necessary to develop and implement a successful Urban Greening Strategy (UGS) for the Shoalhaven LGA through Shoalhaven City Council (SCC). Recognizing the essential social, economic, and environmental benefits of urban trees and vegetation, this study will establish the baseline conditions of our urban forest and identify key opportunities for enhancement. The findings will directly inform policy decisions, investment strategies, and community engagement initiatives within the broader UGS framework.

Under the grant, Council will prepare the strategy and begin on-ground works in at least three high-priority areas identified through the Baseline Canopy Study. Beyond the initial implementation, Council will seek further funding and partnerships with local businesses and industries to continue delivering long-term improvements to urban green spaces and waterway health across the local government area.

As part of our broader commitment to community engagement, including collaboration with volunteer community groups, this project features a schools-focused education and activity program designed to connect young people with the Shoalhaven waterways.

Local students will participate in hands-on bush regeneration activities such as weed control and revegetation in riparian and coastal areas. These experiences will offer educational insights into threatened species, water quality, and environmental management.
