Options to manage flooding related to Sugarloaf Creek around Penshurst St, Willoughby

Draft For Public Exhibition -

As you may be aware, Council has engaged stormwater experts to undertake a drainage study for the Sugarloaf Creek Stormwater Drainage Catchment (the Study). The Study has now been completed and we would like to share these findings with you, and also provide you an opportunity to speak with Council’s Stormwater Team about the outcomes of the Study.

The study area includes Penshurst Street, High Street, Rosewall Street, and Lea Avenue in Willoughby and it examined options to reduce the frequency, risk and extent of stormwater flood impacts.

The feedback from residents, along with the findings of the Study, will help inform and guide the future management of the catchment. At this stage no decisions have been made, nor has any funding been allocated to particular actions or options, but rather this is an opportunity to discuss the Study with residents.

Any future work would be subject to Council’s normal annual budget process, and would also include discussions with the NSW Government who own Penshurst Street.

You can view the study and provide comments via the survey below or in written form to the project officers on the right hand side of the page.

Council will also be hosting a community information session:

Date: Wednesday 20 September 2023

Time: 6pm to 8pm

Location: Willoughby Uniting Church 10 -12 Clanwilliam Street, North Willoughby.

Residents can register via contacting Mr. Aston Pei, Councils Design Engineer, at aston.pei@willoughby.nsw.gov.au or via phone on 9777 7809. You are also welcome to drop-in throughout the evening.

It would be appreciated if you can provide comments on the study by Sunday 8 October 2023.

Initial Information - Prior to commencement of Study

During the recent heavy rain events on 8 March 2022, there was significant water inundation running through the Sugarloaf Creek Catchment which included Penshurst Street, High Street, Rosewall Street and Lea Avenue in Willoughby.

Between 6 and 30 June 2022, the Council asked residents and property owners in the area to provide any information on recent or historic flooding impacts, to help Willoughby City Council undertake a technical flood study.

The Council is currently preparing this study which will seek to examine options to reduce the frequency and extent of flooding impacts in this part of the catchment.

Once the draft study is prepared, the Council will contact residents and property owners to alert them that the study is on exhibition, so they can comment on it.

Any recommendations or outcomes from this study would inform Council’s short and long-term works program and occur through Council's normal capital works program. These outcomes could require the co-operation of a range of land owners, including the NSW Government.
