To address the issues of limited recreational use and drainage problems at Sun Valley Park, Partridge was commissioned to undertake the stormwater management and civil design for the upgraded car park and public walkways. The existing park infrastructure, including two basketball courts and public amenities, had reached the end of its life. The flood-prone southern area of the site posed challenges that hindered recreational activities during and after wet weather. The upgraded facilities and effective drainage design aimed to deter anti-social behavior and maximize the park’s potential for the local community.
