No, the current structure is showing signs of distress and would have needed major works in the near future to maintain the wharf to an operation standard.

There was also the issue of meeting accessibility requirements.

This type of wharf extension provides improved disability access to the wharf, as well as minimising the long-term maintenance requirements.

The overall length of the wharf will be extended by 35m.

Additionally, the area before the ramp will be widened for dedicated bin storage.

We looked at the option of a pontoon, however it is not a viable option due to the tidal impact at this location.

Early concepts for the site progressed the option of hydraulic ramp construction. During the development stage, we looked into the longevity of this style, and identified that a hydraulic type of construction would lead to high maintenance costs and maintenance intervention would be required due to the coastal effects of this site.

We moved away from this option due to the impact the construction have on the Posidonia Grass (an endangered species of seagrass) and White Seahorses, as the L-shape would cover a very large area of seagrass.

This type of construction would also reduce the number of dinghy moorings available.

Yes - we considered this during the design stage to ensure the impact on number of dinghy moorings available, the monitoring will continue to be managed by Transport for NSW.

The final number of tie-ups will be determined in the final design.

Yes, the design provides dedicated bin storage on the wharf.

Ladders will be installed on both sides of the wharf to provide additional access means for residents.

Tidal steps have been provided on the southern side of the wharf for day-to-day access by visitors and occupants.

The ferry will use the ramp for access on the northern side of the wharf.

During construction:

We are investigating options for a temporary structure for use during construction, this will be discussed with the successful contractor at the tender stage to provide the best outcome. The existing ladders will still be in place.

Yes, we have been working with the ferry operators to ensure the wharf will meet their present and future needs.

The ferry operator will continue to operate on the northern side with the option to berth on the southern side if required by the tidal impact.

Yes, we have been working with the ferry operator regarding ferry overrun and the risk of the occurrence. Any requirements to manage this will be established as part of the final design.

The works are jointly funded by the NSW Government, the Australian Federal Government, and Northern Beaches Council.

We considered carefully how additional boat tie-ups might be provided. However, new tie-ups could not be accommodated at this site due to:

• high wave exposure
• strict environmental protections
• limited workable design options
• heritage considerations.
