About

The Pinehaven Stream Improvements project implements the Pinehaven Stream Floodplain Management Plan (FMP). The project involves a range of structural and non-structural measures designed to reduce the flood risk to the community and the catchment. The overall vision of the FMP is: ‘A prosperous, and safe community that proactively manages the risk of flooding in the Pinehaven catchment’.

This project is challenging to construct due to constraints on site; the team have selected a contractor early to assist with property consultation and enable the design process to scope and develop construction methods. This will assist project delivery timing and minimise construction costs.
