Proposals for reducing flooding on Wakehurst Parkway now open for feedback

The NSW Government planned on investing $400 million in road upgrades around the Northern Beaches Hospital in 2014, soon after the cost had become $500 million and by the end of all the works done, the cost had grown to $700 million. 

''The upgrades will provide customers with a better travel experience, increased capacity on the road network and improved access through the area, including for pedestrians and cyclists.'' the Transport for NSW webpage states.

Part of the 2014 discussion included in the Submissions Report a response to community feedback calling for an upgrade to Wakehurst Parkway section from North Narrabeen to the new hospital stated that;

'Roads and Maritime is currently investigating options to reduce the frequency and severity of flooding on Wakehurst Parkway, however, these do not include widening to increase road capacity. Widening Wakehurst Parkway to up to six lanes in both directions would require further removal of the endangered ecological community Duffys Forest Ecological Community, property acquisition, and would have additional impacts related to noise, air quality, visual amenity, and increased stormwater runoff'.

Last week Council announced they are seeking community views on a study into options for reducing flooding on the Wakehurst Parkway between Sydney Sports Academy and Oxford Falls. 

''The Study is being released now following confirmation the NSW Government has made funding available towards the delivery of some of the options outlined in the document.'' Council said

Part of Council's announcement was a statement that ''Council will only take up the funding offer under a number of conditions, including community support for the project.''

The Consultation period closes on Sunday June 27th with the feasibility study now available for community comment at:  https://yoursay.northernbeaches.nsw.gov.au/wakehurst-parkway-flood-mitigation 

If you live and/or work in this area, this is an important issue and your input could make a difference in finding a better way forward. When Pittwater Online News approached local community groups and their spokespeople this week for comment on the Council's proposals all pointed out that this is a state road and state government responsibility. 

The funds to be allocated for proposed works present residents with options for reducing but not eliminating floods. Those options available under the allocated funding would destroy a large swathe of its bushland and impact on several threatened fauna species as well as those that moved from one reserve to the other to feed - our local wallabies for instance. There are also Endangered and Threatened ecological communities in the subject areas which are home to keystone species.

All of the local organisations have stated the Northern Beaches Council should approach the state government for a better solution. 

All have stated the road should be elevated at those flood points via bridges which would allow access for wildlife from one side to the other beneath these and permanently fix the flooding problems without impacting on the bushland.

Miranda Korzy, the Greens candidate for Pittwater at the coming council election, said that since the NSW government closed acute services at Mona Vale Hospital two years ago, the fastest route from Pittwater to the nearest emergency department is along Wakehurst Parkway.  

Yet the government and council, which supported the new hospital site, must have known that this road is flood prone and its single carriageway closes when there’s an accident or bushfire, Ms Korzy stated.   

“The council has placed residents in an impossible position asking them to choose between a set of unacceptable options,” Ms Korzy said this week. 

“They’re now asking us to choose between upgrading that road, which would still flood at times anyway - and protecting the surrounding environment. 

“We must have fast and reliable access to the hospital, but the trees must be protected.” 

Six out of seven of the options would have a significant impact on bushland – destroying up to 2,000 trees – an area the size of a small forest. And we have a duty to protect vulnerable species like the Powerful Owl, Large Eared Pied Bat and Red-crowned Toadlet, that live in the bush surrounding Middle Creek. 

The only option {in the proposals on exhibition) not expected to cause significant environmental damage would involve building a levy on one section of the road, which would make only a minor reduction in flooding – and possibly create ‘some negative impacts at certain flood return periods’. 

“Finally, it’s hard to accept the proposal’s statement that ‘Background research and field inspection of the study area’ were enough to conclude that none of the known 59 Aboriginal sites in the area would be impacted,” said Ms Korzy, who has addressed the council on a number of occasions about problems with the road.

“We can’t afford to lose yet more bushland because of poor hospital planning. 

“It should not be the council’s responsibility to fix a state road that provides access to a major piece of state infrastructure. 

“It must go back to the state government and ask for a properly funded solution that raises the road without destroying the forest.”  Ms Korzy stated.

Miranda Korzy's list of Wakehurst Parkway constraints:

  • Protection of wildlife, including endangered species, in this tract of bushland many of us regard as the gateway to Pittwater.
  • The need to prevent sedimentation in or pollution of Narrabeen lagoon and its catchment. 
  • Protection of all Aboriginal sites in the vicinity.
  • Safeguarding the beauty of the valley and preventing further noise pollution.
  • Sea level rise which could put more of the road underwater.
  • Finally, the upgraded Wakehurst Parkway must not be a tollway – operated by Transurban or any other company - as was flagged in 2017.  Drivers should not have to pay to access the hospital.

The list compiled from feedback sent in from other community groups for reducing (Note: reducing not removing) the numbers of days per year that the Wakehurst Parkway needs to be closed due to flooding includes:

1. None of the presented proposals will prevent ALL flood events along the Wakehurst Parkway, particularly if you take into account the increasing frequency of flood events predicted due to Climate Change.

2. In common parlance, the proposals are "Band-aid Solutions" that fit within the given budget provided by the Roads and Maritime Services (RMS) for now. 

3. Wakehurst Parkway is a STATE road and, with the Hospital and proposed Frenchs Forest area development at the top of the hill, the Parkway is a crucial link that needs to be properly funded by State Government.

4. The Northern Beaches Council has been requested to provide solutions that involve using the surrounding bushland - letting the RMS off the hook from having to do anything about the road itself. 

5. The RMS may say that the water comes from the surrounding environment and that the administrators of the bushland must solve the problems but actually, it is the alignment of the road that has caused the modification of the surrounding environment that now causes the flooding.  It is the road that needs to be modified not the surrounding environment.

6. The flooding occurs at several different locations along the Wakehurst Parkway.

7. ALL the given proposals involve serious environmental disturbance including 

 a)  removal of large areas of bushland and

 b)  exposing contaminated sediments that would need to be treated (and the cost of de-contaminating those sediments is not revealed)

8. There is no discussion of other solutions to the flooding issues - such as raising the road or building bridges at critical points.  The RMS has studied some of those solutions and concluded that they are too expensive but there is no mention of them in the current list of options.  The public deserves to know the cost of doing the flood proofing PROPERLY. 

9. If the road were elevated by bridges, animals could move through underneath.  The road needs to be redesigned to allow for animals to move safely from one area of bushland to another.   

10. It is not a satisfactory process to ask the public to choose between bad solutions and worse solutions without revealing the costs and the environmental impacts of a good or better solution.

All these organisations are asking residents to ''make sure you put in a submission, and if you think the environmental and economic costs of permanently flood-proofing the road ought to be revealed and discussed before any decisions are made, then please say so.''

If so much can be spent on road upgrades around the new hospital that stretch of the Wakehurst Parkway between Oxford Falls and Pittwater Road, North Narrabeen has been denied a proper investment for too long. Your feedback will support and empower the Council and the State Government and our local representatives in Member for Pittwater Rob Stokes, Member for Wakehurst Brad Hazzard and Member for Davidson Jonathan O’Dea, to finally choose and fully fund the option that will fix the problem while still retaining the bush and in doing so, save the lives of all the wildlife and endangered plant communities it is our privilege to be the current custodians of, as well as save human lives where motor vehicle accidents still occur on a weekly basis.

Only by taking part in the discussion can you help shape the outcome.

Middle Creek Bushland Reserve

Middle Creek Reserve is located along the Wakehurst Parkway and contains one of the highest conservation bushland areas on the Northern Beaches. Middle Creek and its tributary, Trefoil Creek, form part of an important wildlife corridor linking large areas of bushland reserves in the south of the Beaches with the extensive bushland to the west including Garigal National Park and Narrabeen Lagoon catchment to the south.

Nine native vegetation communities were identified in the study area. These included four endangered communities (swamp oak forest, bangalay alluvial forest, water fern swamp and estuarine paperbark scrub, the last three of which are all forms of swamp sclerophyll  forest on coastal floodplains), two regionally significant communities (seagrass meadow and coachwood rainforest), and three other communities (peppermint-angophora forest, bloodwood-scribbly gum woodland and sandstone heath). A total of 313 native plant species has been recorded in the catchment area including three rare Australian species (Angophora crassifolia, Darwinia procera and Lomandra fluviatilis), 23 species considered threatened in northern Sydney, four species considered threatened on the Northern Beaches, and eight biogeographically significant species. 

A total of 138 native fauna species have been recorded in or near the Middle Creek area, consisting of five frog species, 18 reptile species, 100 bird species and 15 mammal species. These include nine threatened species: giant burrowing frog, Rosenberg's goanna, black bittern, osprey, glossy black-cockatoo, powerful owl, spotted-tailed quoll, frey-headed flying-fox and common bentwing bat. Of special significance is an osprey nest tree, which was the site of the first successful breeding record of the species in the Sydney region.

Deep Creek Bushland Reserve

Deep Creek Reserve is located along Wakehurst Parkway and is one of the Northern Beaches highest conservation reserves. The reserve contains a small freshwater wetland on  the lower section of the reserve which is a form of Sydney Freshwater Wetlands, listed as a Threatened Ecological Community in NSW. This reserve contributes to a regional corridor providing movement for an abundance of native animals including threatened pygmy possums (Cercartetus nanus), powerful owls (Ninox strenua) and heath monitors (Varanus rosengergi).


Vegetation communities in the reserve include Coastal Freshwater Wetlands, North Coast Wet Sclerophyll Forests, Sydney Coastal Dry Sclerophyll Forests, Coastal Freshwater Lagoons and three Threatened Ecological Communities Swamp Oak Floodplain Forest, Sydney Freshwater Wetlands and River Flat Eucalyptus Forest. Dominant trees located on the sandstone ridgetop of the reserve include Sydney Redgum (Angophora costata),  Sydney Peppermint (Eucalyptus piperita) and Red Bloodwood (Corymbit gummifera) and on the floodplain She Oaks (Casuarina glauce). 

Within the shrub layer, flora species include Christmas Bush (Ceratopetulaum gummiferum), Sunshine Wattle (Acacia terminalis) and Old Man Banksia (Banksia serrata) and  within the floodplain and wetland areas dominant species include ferns (Calochlaena duba) and (Blechnum cartilagineum), sedges (Baumea Spp.) and (Juncus prismatocarpus) and rushes (Gahnia Spp) all of which provide important habitat for several species of frogs.


The habitats within Deep Creek Reserve and its connectivity to Garigal National Park and the Narrabeen Lagoon State Park make the area one of the most diverse reserves on the Northern Beaches for fauna. It is estimated that over 100 species would use the reserve with many of these being permanent residents. The reserve contains large tree hollows which are used by arboreal mammals, bats and a variety of birds. The rocky outcrops, fallen logs and thick groundcover provide niches for reptiles, frogs and small mammals. The vast array of flowering plants within the reserve are an important resource for both insectivorous and insectivorous birds, mammals and insects.

Several threatened species have been recorded in the vicinity and many more are likely to use Deep Creek Reserve including; Australasian Bittern (Botaurus poiciloptilus) and Black Bittern (Ixobrychus flavicollis), Glossy Black-cockatoo's (Calyptorhynchus lathami) which feed on the Casuarina seeds, Powerful Owl (Ninox strenua) and Masked Owl (Tyto novaehollandiae) that will prey on arboreal mammals such as possums and gliders.

Call For Community Feedback On The Wakehurst Parkway Flood Mitigation Study

Wednesday, 24 March 2021: Northern Beaches Council Media Release
Northern Beaches Council will be seeking community views on a study into options for reducing flooding on the Wakehurst Parkway between Sydney Sports Academy and Oxford Falls.

The Study is being released now following confirmation the NSW Government has made funding available towards the delivery of some of the options outlined in the document. Council will only take up the funding offer under a number of conditions, including community support for the project.

Mayor Michael Regan said it was time for the community to have their say on the approaches available to reduce flooding impacts.

“This a major state-managed arterial road which is closed by flooding approximately six times a year – creating a huge inconveniences for many motorists – which is why we lobbied the State Government for funding for the Study and potential works.

“However, the Study confirms there are no easy or quick fixes for this issue.

“The road runs through the middle of a sensitive, rich ecosystem supporting an array of threatened plants and animal species, and there are no options that fix the wider flooding problem without environmental impacts.

“We are right at the beginning of the process – commissioning this feasibility study was the first step in order to get a sense of the options available.

“We have a lot more work to do to make sure we have a full and extensive picture of what flood mitigation measures will mean for the sensitive environment.

“In the meantime, it’s important the community has an opportunity to have a look at the options documented in the Study and give their initial feedback for us and the State Government to consider. We’ll only proceed with options if we have general community support.

“As this is a significant project, this will be the first of a number of times the community will be asked for input.”

The NSW Government announced in November it would allocate a further $13.1 million to reduce the frequency of flooding along Wakehurst Parkway and have since written to Council outlining the funding offer.

“The NSW Government has been proactively working with Council to assist with funding for this significant project.

“This allows us the certainty to begin engagement with the community.”

The feasibility study is expected to be available for community input in May.

Wakehurst Parkway Flood Prevention Works Funded

Thursday, 19 November 2020: by Northern Beaches Council
Additional funding from the NSW Government means works to reduce the frequency of flooding along the Wakehurst Parkway is now a step closer.

As part of the NSW Budget, $13.1 million has been allocated to help solve some of the issues facing this important road connecting the northern beaches with Chatswood and the CBD.

The road is also an important gateway to the Northern Beaches Hospital, with the proposed works intended to keep the road accessible to drivers following heavy rain.

The multifaceted flood mitigation will involve works at three key locations including new under road culverts and drainage, creek realignment, sediment removal and new levees.

Now there is funding certainty for the project, we will look forward to bringing more details about the potential options to the elected Council and the community in the new year.

This initiative is the result of a fantastic partnership between Council and the NSW Government and particularly local MPs Jonathon O’Dea, Rob Stokes and Brad Hazzard who have been instrumental in ensuring this project comes to fruition.

Budget injection for Wakehurst Parkway

Wednesday, 18 November 2020: Northern Beaches Council Media Release
Northern Beaches Mayor Michael Regan today welcomed funding measures in the State Budget dedicated to addressing local issues for the State’s fourth-largest council.

The NSW Government announced it would allocate a further $13.1 million to reduce the frequency of flooding along Wakehurst Parkway, bringing total funding for that project to $18.1 million.

A comprehensive flood and ecological study was commissioned by Northern Beaches Council and funding for some of the recommendations has been discussed with the NSW Government over the last year.

“I would like to thank the State Government for its ongoing partnership in solving some of the issues facing the Wakehurst Parkway,” Cr Regan said.

“This extra funding will help improve access to the Northern Beaches Hospital, and will make a difference to the issues motorists face regularly on the Wakehurst Parkway following rain.

“Now we have more certainty around funding and what’s possible to deliver, we look forward to bringing details to the community.

“This is another great example of how state and local government partnerships can make a big difference to our community.”

Cr Regan said the Budget showed the Government had shown confidence in the work of local governments, supporting council to drive locally-led economic recovery following a devastating year of drought, bush fires and a global pandemic.

Funds For Wakehurst Parkway Flood Mitigation

August 24, 2017
Member for Pittwater Rob Stokes, Member for Wakehurst Brad Hazzard and Member for Davidson Jonathan O’Dea today announced up to $5 million to support the introduction of flood mitigation measures along Wakehurst Parkway.
Earlier this year Northern Beaches Council began investigating environmental measures to help address intermittent flooding caused by the overflow of Middle Creek.
An interim report presented to Council this week has found that making changes to Middle Creek, and removing vegetation, may be able to reduce road closures in smaller but more frequent flood events.
Up to $5 million will be made available by the NSW Government to support Council’s detailed investigation and the implementation of any practical actions to reduce the frequency of flooding.
Member for Pittwater Rob Stokes said, “This is an important opportunity to see progress on this issue.
“Wakehurst Parkway winds through a unique area and there are a range of factors to consider.”
Member for Wakehurst Brad Hazzard said, “We love our bush along the Parkway and hopefully these funds will allow preservation of the bush at the same time as the flooding risks are reduced.”
Member for Davidson Jonathan O’Dea said, “There are indications that the environmental treatment of vegetation and changes to Middle Creek will help reduce road closures. These should be pursued as initial measures.
“I’m pleased Northern Beaches Council has taken the initiative and the State funding will help support these efforts.”

August 22nd, 2017 Minutes showed the The Northern Beaches Council have completed initial investigations into reducing the small scale but frequent flooding which closes Wakehurst Parkway and will now carry out detailed design assessments in order to finalise options. Council set up an interagency working group to identify the factors causing the frequent smaller floods and find potential ways of stopping it. The next stage involves detailed assessment of flood behaviour, creek depth and alignment, creek configurations and assessments of potential environmental impact. Work will start next month, with options and/or designs likely to be confirmed in about 12 months.

The Council established a working group with Roads and Maritime Services. Council engaged specialist flood consultant Cardno to undertake a preliminary flood investigation of Wakehurst Parkway. The Working Group members met with Cardno on site to inspect the flood locations, with RMS providing data from their previous investigations.

Investigations have determined that Wakehurst Parkway floods in four separate locations and has required closing between 3 and 11 times a year between 2007 and 2014. An assessment of the rainfall conditions during this period has indicated that these locations flood in rain events with a magnitude of less than a 1 in 1 year event.

A number of preliminary floodplain mitigation options have been investigated including sediment removal from Middle Creek, culvert upgrades, detention basins and the raising of Wakehurst Parkway. Early results suggest that the removal of sediment from Middle Creek could provide minor reductions in flooding in the short term however further analysis is needed and any works would require ongoing maintenance and would be associated with environmental impacts. The raising of Wakehurst Parkway in key locations and corresponding culvert upgrades appears to provide a longer-term sustainable option to permanently reduce the incidence of flooding and road closures in all events up to the 1 in 20 year rain event, however this has a significant capital cost and is also likely to have environmental impacts.

The preliminary assessment clearly shows there are options for managing flooding. The project will now move into the detailed analysis, feasibility assessment and cost-benefit comparisons to determine the preferred approach.

Funds For Improved Floodplain Management

4 December 2015

Member for Pittwater Rob Stokes today announced NSW Government funding to help improve local floodplain management.

Pittwater Council has been allocated $220,000 to assist with the preparation of floodplain management strategies and the development of warning and information systems.

Key locations identified for upcoming projects include residential areas surrounding Narrabeen Lagoon and Great Mackerel Beach.

“Floodplain management is an ongoing challenge for our community,” Rob Stokes said today.

“Over recent years Pittwater Council has done considerable work identifying and limiting flood risks and it’s important this work continues.

“There’s often no single solution to addressing flood risks - but forward planning and strategic management can make a huge difference.

“Unfortunately floods and natural disasters are inevitable and all communities must be as well prepared as possible.

“I’m pleased the NSW Government is continuing to support Pittwater Council with its endeavours and I look forward to the overall benefits for our community,” Rob Stokes said.

 Almost $5 Million In Floodplain Management Grants 

Wednesday, 2 December 2015

Environment Minister Mark Speakman today announced $4.93 million in grants for 10 councils and a local land service to address flood risks throughout NSW.

Mr Speakman said the funding for councils was another way the NSW Government was supporting communities to prepare for extreme weather events well in advance of them occurring.

 “Floods and natural disasters are an inevitable reality in Australia and it is important we support our councils to consolidate the safety of people and property in our communities,” Mr Speakman said.

“The projects are funded under the State Floodplain Management program that works to ensure landowners, businesses and local economies are prepared to meet the challenges of floods and natural hazards.

“Losses from flooding in NSW can be high. Floods can cause irrevocable damage to not only the physical but the emotional wellbeing of our communities.”

The grants will help councils to be better equipped to implement floodplain risk management plans and to prepare the regions that are affected by flooding.

Examples of new projects to be funded include:

• $3.66 million to Murrumbidgee Shire Council to continue the Darlington Point Levee, which once completed will protect the town from most flood events;

• $140,000 to Dungog Shire Council to develop a flood risk management study and use information from the April floods to review its existing studies and determine suitable mitigation strategies.

Great Mackerel Beach Entrance Management Strategy (SFMP)              

The Great Mackeral Beach residents experience periodic flooding which has been attributed to the closed entrance. This study will assess the entrance processes at Great Mackeral Beach and examine any environmental impacts associated with cyclical dredging being incorporated into an ongoing entrance management strategy. An Entrance Management Policy will be developed and will enable a timely and effective response to better assist affected residents.

North Narrabeen Lagoon Overland Flow Flood Study (SFMP) 

Council will undertake a flood study to identify the overland flow paths within the Elanora Heights and Ingleside area, as well as look at how the overland flow paths interact with the mainstream Narrabeen Lagoon flooding.

Northern Beaches Flood Warning and Flood Information Network (SFMP)         

This is an ongoing project that provides a strategic regional approach to the management of rainfall, flow and water level gauges. This information is essential to Council and the public in managing lagoon and flash flooding. The program will keep the website up to date with flooding information and add an additional flood gauge to the network.

Newport Flood Study (FRMGS)   

Council will update the existing Flood Study to ensure overland flow paths entering the mainstream catchment are appropriately identified and mapped. It will look at the interactions of the mainstream flooding and the many overland flow paths within the study area.


Jason Falinski Fights For Wakehurst Parkway Upgrades

February 14, 2020: from Mr Falinskis' office
Member for Mackellar, Mr Jason Falinski MP is campaigning to have the Wakehurst Parkway upgraded. The Northern Beaches community have been demanding this for years and Mr Falinski is arguing that following the recent storms, the flaws of the road corridor are yet again exposed.

“It is absurd that with even the slightest of rainfall, we lose one our main roads. Not only is it inconvenient, but it’s dangerous. We are lucky to have a state-of-the-art hospital in Frenchs Forest, however access becomes very difficult when this road is blocked.” Mr Falinski said

“Currently, it is a two-lane road, which is grossly inadequate to cope with the volume of traffic it receives, not to mention when there are car crashes.”

“It needs to be flood proof and it needs to be widened.”

Mr Falinski has already begun conversations with the Minister for Urban Infrastructure, the Hon Alan Tudge MP who indicated funding for the study could be made available through the Federal Government’s $4 billion Urban Congestion Fund.

Mr Falinski has also contacted the New South Wales Minister for Roads and Transport, the Hon Andrew Constance MP and implored him to ask Minister Tudge for the funding.

“I have written to Minister Constance on behalf of my community imploring him to work with the Federal Government to get a feasibility study underway and then get this project going.”

Mr Falinski has said he is willing and able to facilitate a meeting between the two Ministers.

Early investigation work for the Stage 1 Connectivity Work started in August 2015 and Stage 1 construction commenced in November 2015. By August 2020 the works had been completed. 

The spend and works done included, in 2018, moving over 100,000m3 of dirt and fill, pouring 14km of concrete paths, Opening Naree Road, Frenchs Forest Road West and East to two lanes in each direction, completing the entrances to the new Northern Beaches Hospital, constructing and opening the new westbound lanes on Warringah Road, upgrading and opening the eastbound lanes on Warringah Road, opening shared paths and new footpaths throughout the project area, installing six new sets of traffic lights, major intersection upgrade at Wakehurst Parkwayand Frenchs Forest Road, starting construction of the road bridges at Forest Way, Hilmer Street and Wakehurst Parkway, completing 20 new car parks for the Skyline Shops.

In 2019 the project was excavating the 1.3 km long Warringah Road underpass from west of Forest Way to east of Wakehurst Parkway, reconfiguring the intersection of Warringah Road and Forest Way for the continued construction of the Warringah Road underpass, new road, kerb and gutter at Allambie Road south of Warringah Road, and Warringah Road between Allambie Road and Rodborough Road, opening new sections of the eastbound lanes on Warringah Road between Fitzpatrick Avenue West and Forest Way, and east of Wakehurst Parkway to Rodborough Road, completing the intersection of Warringah Road and Hilmer Street, including the bridge over the Warringah Road underpass, traffic changes at the intersections of Forest Way and Wakehurst Parkway for the continued construction of the bridge at each intersection over the Warringah Road underpass. The underpass bridge at Hilmer Street was opened in March 2019 and the underpass bridges at Forest Way and Wakehurst Parkway were completed in September 2019. The Warringah Road underpass opened to traffic in March 2020.
