This important upgrade will improve how stormwater is managed within the reserve.

The detention basin’s spillway plays a key role in regulating water levels and protecting community assets, including the Sellicks Beach Community Centre, playcentre and surrounding open space.

This project is solely focused on improving how stormwater is managed within William Eatts Reserve. It is not connected to any potential future growth or development in Sellicks Beach. The upgrade has been initiated to address current stormwater flows and improve the performance of existing infrastructure, particularly during heavy rainfall events.

What’s happening

The existing detention basin will be enlarged to increase capacity during heavy rainfall. This will involve:

  • Enlarging the detention basin footprint
  • Removing and later replanting some recently planted trees

All facilities within William Eatts Reserve including the community centre, tennis courts, playcentre and community garden are expected to remain open and accessible during the works. While there may be temporary relocation of parking and some construction noise or dust during work hours, reserve activities are anticipated to continue as normal.

How to get involved

We’re committed to keeping the community informed and involved.

Concept plan showing proposed upgrades to the Riviera Road stormwater detention basin in Sellicks Beach. Key features include basin enlargement, rock mattress chutes for water flow control, low mounding with hydroseeding, removal of one tree, landscaping

This plan shows proposed improvements to the stormwater detention basin near the Sellicks Community Hall. The key features include:

  • Widening of the existing detention basin to improve stormwater capacity
  • Addition of rock-lined chutes to manage water flow
  • Landscaping across the basin area, including planting and feature rocks
  • Removal of some existing trees and retention of others. Following the civil works we will plant trees and shrubs, that include the species that were planted in previous years by the community.
  • The nearby tennis courts, carpark, and play area are shown for reference

These upgrades aim to better manage heavy rainfall, reduce erosion, and improve the appearance of the area.

Removal and replanting information

We’ll remove a small number of trees and plants so the basin can work safely during big rains. In their place we’ll replant 10+ trees and hundreds of shrubs and grasses—more than we remove.

All species are carefully selected to boost shade, habitat and creek health, and they’re matched to the basin’s wet/dry zones to help them thrive.

Some of the selected plants are detailed below however these are just a few examples of the plants that will be enhancing the space.

Trees

  • River Red Gum
  • Grey Box
  • Peppermint Box
  • Mallee Box

Shrubs & groundcovers

  • Sticky Hop Bush
  • Ruby Saltbush
  • Marsh Saltbush
  • Mallee Bush Pea
  • Round-leafed Pigface

Grasses, sedges & rushes

  • Kangaroo Grass
  • Rush Sedge
  • Salt Club Rush
  • Pale Rush

Plants will be installed after civil works have been completed and will be monitored and supported to help them establish.
