The construction of a vegetated infiltration basin at Golden Beach was completed in September 2015. The basin was designed to reduce the stormwater impacts from the local Earnshaw Street catchment on Pumicestone Passage.
To provide feedback to the community, the stormwater industry and council on the function and performance of vegetated infiltration basins in a dunal environment, a Community Monitoring Program was established. Members of the local Golden Beach community, representatives from the University of the Sunshine Coast and council officers have been involved in overseeing and delivering the monitoring program.
The vegetated infiltration basin at Golden Beach was designed to treat diverted stormwater from the Earnshaw Street catchment before it discharges to Pumicestone Passage. The basin has been designed to capture the initial stormwater runoff from the local catchment. This allows the sediment in the runoff to settle onto the basin floor while the remaining water infiltrates through the soils below the basin. Nutrients in the stormwater runoff are absorbed by the vegetation both in and surrounding the basin. This helps the plants to grow, which then strengthens the dunes helping to protect them from tides and weather events. Figure 1 below illustrates the key elements of the Vegetated Infiltration Basin.
Since construction of the basin was completed in September 2015 routine maintenance of the basin is undertaken and any accumulated rubbish, such as litter and bottles, is removed. A new information sign was erected on site and the Community Monitoring Program commenced.
Monitoring results are available for groundwater and sediment sampling.
OverviewThe basin was designed to fit into the surrounding environment, park and adjacent coastal pathway. Low growing plant species have been carefully selected to ensure the basin blends into the surrounding landscape and views of Pumicestone Passage are not affected as the plants grow.

The Pumicestone Passage and Catchment Action Plan 2013-16 lists Golden Beach as a committed site for this important council project. The Pumicestone Passage waterway has high environmental values, with many plant and animal species and is listed under the Convention on Wetlands of International Importance as an important site for migratory birds and it also supports diverse wildlife including turtles, dugong in southern areas, fish, crabs, oysters and juvenile prawns.
