Austinmer stone wall replacement

Wollongong City Council is replacing a low dry-stacked stone wall in The Grove, Austinmer, due to concerns of slope slippage and trees falling onto the road.

One vehicle traffic lane will be closed each day during the works with traffic lights controlling vehicle movements adjacent to the work zone.

The existing wall, adjacent to residences 25-29 The Grove and approximately 35 metres long with a maximum height of a metre, has failed due to softer clay stones used in the original construction as well as the impact of tree roots.

The replacement wall will use durable sandstone rock, and along with a slope stability mat and replanting, will provide long-term stability to the embankment behind the wall.

Following feedback from community consultation the number of trees to be removed was reduced from 11 to three, with any further removals subject to soil stability and pending an arborist report.

The work also includes construction of a reinforced concrete dish drain for improved stormwater management.

The works are due to start on 1 July and last approximately eight weeks, weather permitting.
