Alkimos Water Precinct power supply upgrade

It is unlikely that any power supply interruptions will be required for this work. If an outage is required, Western Power will inform customers in advance.

This power supply upgrade will benefit the Alkimos Water Precinct. Wester Power has a separate program of work to reinforce and strengthen the grid in the area and across its network. Please contact Western Power for more information.

Yes, however during the four-week eastbound lane closure of Graceful Boulevard between Pectoral Promenade and Turnstone Street, eastbound traffic travelling to the shopping precinct from the west will need to access Turnstone Street via Tawny Way or Sanderling Street

Westbound traffic travelling from Marmion Avenue or Romeo Road will still be able to access the shopping precinct via Graceful Boulevard and Turnstone Street.

We will be tunnelling under Turnstone Street to keep access open to the Alkimos Gateway Shopping Precinct.

We encourage businesses to let us know how we can minimise impacts on their business during construction.

The eastbound lane between Painted Parkway and Pectoral Avenue will be closed for around five (5) months, during this time there will be no right turn onto Graceful Boulevard (travelling East) from the connected residential streets.

Residents living on the connected streets (listed below) will be required to travel south to access Fairy Parade, Leatherback Boulevard or Hawksbill Drive when driving east.

• Whipbird Road
• Woodswallow Way
• Crowed Way
• Tristan Way
• Scrubwren Circuit
• Ruff Way
• Quoll Mews
• Painted Parkway

We apologise for the inconvenience. 

Planning has been undertaken to reduce the impact on vegetation along Graceful Boulevard as much as practically possible.

At this point in time, one tree will be removed along Graceful Boulevard where the new infrastructure enters the Alkimos Water Precinct.

Western Power's contractor will work closely with the City of Wanneroo to replace all vegetation that is impacted.

The shared paths at the corner of Marmion Avenue, Romeo Road and Graceful Boulevard will temporarily be impacted during the tunnelling work on the corner. Detours will be in place to safely direct users around the work area.

The shared path between Pectoral Promenade and Marmion Avenue will remain open.

The shared path on the northside of Graceful Boulevard between Painted Parkway and Pectoral Promenade will be closed for around five (5) months while work is completed in the area. The shared path on southside of Graceful Boulevard will remain open. Detours will be in place to safely direct users around the work area.

All impacted areas are replaced like for like, where practically possible. Unfortunately, the work will result in unavoidable impact to roads and verges. Western Power's contractor will work closely with the City of Wanneroo to ensure all reinstatements are carried our to an acceptable and high standard.
