The fight against rezoning

On 18th June 2020, the site at 55 Coonara Ave was rezoned from a business park to residential and environmental conservation. The rezoning went against the wishes of the local residents, community groups, Hills Shire Council and Hornsby Council. There were more than 4000 submissions objecting to the rezoning.

1 October 2020

PYSE (Protecting Your Suburban Environment Inc) investigated a potential legal challenge to the rezoning.

PYSE obtained initial legal advice which indicated potential grounds for an appeal against the Department of Planning's rezoning. PYSE then obtained a Barrister's advice as to whether they had reasonable prospects of winning a Judicial Appeal. The Barrister advised that even though the rezoning decision was considered not to be a good decision, in their opinion PYSE was unlikely to meet the high bar that is required for a successful Judicial Appeal.

Although PYSE was unable to fight the rezoning in Court, their legal team identified significant issues with the Mirvac proposal.

18 June 2020
DPIE approved the rezoning of this site for residential and environmental conservation.

DPIE amended the proposal rejected by Hills Council last November to:

  • reduce areas of land to be zoned R4 high-density and R3 medium-density residential;

  • increase areas of land to be zoned E2 environmental protection;

  • remove a proposed RE1 Public Recreation zone (and associated synthetic grass playing field);

  • include additional local provisions to allow recreation and selected other uses consistent with the objectives of the E2 zone (these provisions only apply to E2 areas previously proposed as R4 and RE1); and

  • ensure asset protection zones (APZs) do not require clearing or management of critically endangered ecological communities.

Some of the E2 area may be dedicated to Cumberland State Forest, via a Voluntary Planning Agreement between Mirvac and DPIE, but this was not a condition of rezoning. Mirvac has said this will happen 'prior to the issue of the Occupation Certificate for the final stage of the proposed development' (Construction work is estimated to take at least 5 years)

22 May 2020

NSW Planning included this project on the list for Fast-tracked Assessments, Tranche 2, with a decision due by 18th June.

Click here for the Media Release. The project is described as 'an expansion to Cumberland State Forest'!!

Criteria for Priority Projects can be viewed here. This project does not satisfy the criteria for creating jobs after construction, delivering affordable housing, or timeliness because ecology, bushfire and flooding restraints can't be resolved quickly.

Residents were urged to take immediate action to stop NSW DPIE giving in to pressure from Mirvac.

WPHVPA printed over 6000 leaflets which were delivered by our team of volunteers, together with helpers from other local community groups.

May 2020

We sent further letters to Rob Stokes (NSW Minister for Planning) and to Dominic Perrottet (NSW Treasurer) saying that the 2019/20 bushfires and COVID-19 have provided further reasons to reject this proposal.

April 2020

Urban Taskforce (a lobby group for developers) placed 55 Coonara Ave on a list of projects that could be fast-tracked to help stimulate the NSW economy.

The list was part of a submission made by Urban Taskforce at the request of NSW Treasury Dept, and is supposed to be for projects that are ‘shovel-ready’ but stuck in the NSW planning process. You can read the whole report here. Details for 55 Coonara can be found on page 52 of the report.

Unlike other projects on the list, 55 Coonara was not stuck in the planning system. the proposal was rejected at the Council Meeting on 26th November 2019. We wrote to several politicians pointing out that 55 Coonara should not be on this list because it is not stuck in the planning system. We asked for 55 Coonara to be removed from the list of projects being considered.

David Elliott replied with the comment ‘‘I’m assured that any stimulation of construction sector won’t be at the expense of integrity of the planning laws.’ The response from Treasury/NSW planning response is here

The Dept of Planning & Environment updated information on its website about the Cherrybrook Precinct. Information about future plans now refers only to government owned land. There is a revised map for Cherrybrook Station Precinct and the Mirvac site is no longer included in the precinct plan.

September 2018

A revised proposal was voted on at the Council meeting on Tuesday, 25th September. The proposal was approved by 8 votes to 5.

13th June 2018

The Department of Planning issued an alteration to the Gateway Determination, rejecting most of Council's amendments.

Most of Council's requests to amend the original Determination were rejected. In particular, Council was requested to seek the highest level of environmental protection for relevant portions of the site, and the Department was satisfied that rezoning of land to E2 does not give rise to the need to compensate a landholder. Also, there was no alteration to the requirement to consider and propose the RE1 Public Recreation Zone.

Read the Gateway Alteration and Letter to Council dated 13-06-2018.

January 2018

An open letter objecting to Council's request to amend the Gateway Determination was sent to NSW Planning, various other levels of government, and media.. The letter was signed by several local community groups including WPHVPA.

12th December 2017

Council voted on a revised rezoning plan at its meeting on 12th December. The new zoning proposal was approved by 8 votes to 4.

Read the full report on the Council agenda for this meeting, or just read the important bits : Executive Summary & Land Use Zones & Map Far from protecting the forested parts of the site with an E2 zoning, Council supported E3 zoning which would allow residential development on the land. Read the Council Minutes for this item. On 15th December 2017, Council sent a letter to Dept of Planning requesting an alteration to the Gateway Determination to reflect the new zoning proposal.

November 2017

The Department of Planning made a determination to allow the Mirvac development to proceed subject to Council meeting a number of conditions.

The Hills Shire Council was required to specify which parts of the Mirvac property it wished to rezone as High Density residential development and which parts were to be reserved for environmental protection. This need for transparency was a significant step forward. More information was required in relation to transport and infrastructure. Council was also required to consult other bodies such as the Rural Fire Service.

Read the Gateway Determination & Letter to Council.

25th July 2017

Council voted to support a revised proposal for 600 dwellings.

The proposal includes a mix of high and medium density housing, a community building and a sports field.

The Gateway process allows for consultation with the NSW government and the public to occur. The Mirvac proposal was lodged with NSW Dept. of Planning and Environment on 14th August 2017.

28th March 2017
Planning proposal (20/2016/PLP) for high density residential development of 55 Coonara Ave was rejected by Council.

The report included in the meeting agenda recommended rejecting the planning proposal in favour of retaining the current business park zoning. A motion to adopt the recommendation in the report (and reject the proposal for high density residential development) was put to the meeting and carried.

  • The proposal being considered by Council was for 800 units up to 8 storeys high. The proposal included converting current open space to a sports ground, retaining the treed area in the southern part of the site and retaining a treed buffer between the Cumberland Forest and new buildings. The existing multi-storey carpark would be retained but the current office buildings would be removed.

  • An initial proposal by Mirvac was for 1200 residential units up to 25 storeys. This was rejected by Council as was a second proposal for 1000 residential units.
