Dan Mahoney Reserve, North Parramatta

December 2020

With newly planted grass now well established, contractors will be removing the majority of temporary fencing in early December.  The new grass will then be mown progressively lower, over several weeks, until it is the same height as the rest of the reserve.  This gradual mowing technique is necessary to prevent damage to the base  (known as the "crown") of the grass and maintain grass health.

Temporary fencing will continue to be placed and removed on an as-needs basis.

June 2020

Following delays caused by wet weather in May, asphalting works at the reserve are expected to recommence on Tuesday, 9 June, and be completed by Friday 12 June.

Asphalting works at Dan Mahoney Reserve

18 – 25 May 2020

The City of Parramatta and licenced contractors will be installing asphalt in front of the amenities block and park benches in Dan Mahoney Reserve over a one-week period from Monday 18 May to Monday 25 May 2020 (subject to weather and  site conditions).

 

This work will help to ensure the ongoing safe management of the reserve, by capping areas where grass coverage is sparse, and new turf installations have been unable to establish.   The works will be carried out in accordance with SafeWork NSW requirements, including the use of appropriate personal protective equipment, and the use of air quality monitoring during ground disturbing works.

To keep residents and their canine companions safe during these works, temporary fencing will be installed around the construction zone closing these areas to the public.   Residents and their dogs will be able to use other sections of the reserve while the asphalt laying and associated works are in progress.  During the works, access to the amenities building may be limited.

Fenced areas re-opened for off-leash play

Returfing and other measures to encourage grass growth has been successful and with ground coverage adequately restored temporary fencing at Dan Mahoney has been removed. 

Prior to opening these areas for off-leash play, the City of Parramatta mowed the grass, leaving it slightly longer than usual to ensure adequate ground coverage is maintained. Air-quality monitoring was undertaken at this time.

City of Parramatta will continue to monitor the site to guard against buried materials becoming exposed. Work to develop a plan for the appropriate permanent treatment of the site continues.

Embankment Works

As a result of environmental investigations conducted in 2018 (see March 2019 update on this page for more information), City of Parramatta Council has commenced a series of interim works programs and remedial actions, which will mitigate the risk of buried material becoming exposed. 

From Monday 3 June 2019, work will commence on the eastern embankment.

While this area will be closed to the public, the rest of Dan Mahoney Reserve will remain open for normal use.

Work on the embankment will include the installation of an erosion control barrier, mulch, and a sandstone block and boulder border. These works are expected to take up to two weeks.

While Council’s contractors will have a traffic management plan in place, Reserve users are asked to exercise caution throughout the works program and to closely supervise their dogs while playing in the Reserve.

Enquiries about the work can be directed to Council’s Dan Mahoney Project Team on 9806 5050.

Dan Mahoney Reserve closed 6 - 13 May 2019 for groundwater testing

 As a result of environmental investigations conducted in 2018 (see March 2019 update on this page for more information), City of Parramatta Council has commenced work to design a new cap for the landfill that exists beneath Dan Mahoney Reserve. 

To prepare this design, engineers need more information about the type and depth of groundwater beneath the reserve.

Specialist environmental consultants have been engaged to undertake groundwater testing. Large drilling machinery will be used to take samples of the groundwater deep beneath the reserve. 

To ensure the safety of park users including residents and their dogs, the works area will be closed to the public during the testing. The western side of Dan Mahoney Reserve will remain open for play (accessible via Waugh Avenue).

Groundwater testing is expected to take a week. The reserve will also be top-dressed as part of these works.

Council staff and contractors will continue to work in consultation with the Heads of Asbestos Coordination Authorities (HACA) including; the Environmental Protection Authority (EPA), SafeWork NSW and NSW Health to ensure that Dan Mahoney Reserve remains safe for public use.

All appropriate safety precautions will be taken during these works with all consultants licensed to safely work in soils affected by asbestos.

Environmental Testing Report 

To plan for the ongoing safe management of Dan Mahoney Reserve, including future maintenance works, City of Parramatta Council commissioned highly-qualified, independent consultants to conduct environmental testing.

Testing was performed in September and October 2018.

Given Dan Mahoney Reserve’s history as a landfill site, consultants were to provide information on the type and quantities of any potentially hazardous materials, including asbestos, that may be present in the landfill beneath the park.

Results

The consultant’s report confirms Dan Mahoney Reserve is safe for use provided that adequate grass coverage or a physical barrier between the landfill and the surface of the reserve (a capping layer) is maintained.   
Air quality monitoring confirmed no airborne asbestos was present during the testing period. Asbestos fibres are only a health risk if they are released into the air and can be inhaled. This is what is known as an “exposure pathway”.

Laboratory analysis of the soil taken from the 45 bore holes dug during testing showed Dan Mahoney Reserve does not contain heavy metal contaminants in excess of the applicable health investigation levels.
Asbestos materials (such as small pieces of fibro similar to material found in many homes) was found in the soil beneath the reserve. 
These results mean Council is undertaking interim works to improve capping layers and will need to plan for longer term treatment or remediation.   

Actions

Council sought advice from its environmental consultants, the EPA and NSW Health, and will continue to consult with these agencies as treatment options are considered and implemented.

Council staff and contractors are undertaking regular inspections to monitor the condition of Dan Mahoney Reserve.

Council is taking immediate action to improve capping layers in the short term, and is seeking advice from specialists to secure the most appropriate permanent treatment of the site.

Current temporary fencing will remain in place in order to prevent public access – helping to encourage grass growth and restore coverage. 

Alternative capping will be investigated for areas where grass coverage is sparse.

In the next few weeks, works including mulching, re-turfing and the use of erosion control products will take place at Dan Mahoney Reserve. 

Council may also extend or install additional hard surfaces including paved or concrete areas as required.  
City of Parramatta will continue to provide the community with information on its management plan for Dan Mahoney Reserve and will update on further works, likely to take place later this year.

Council will continue to seek advice from specialists to secure the most appropriate long-term treatment for the site and will continue to work in consultation with the Heads of Asbestos Coordination Authorities (HACA) including the EPA, SafeWork NSW and NSW Health to ensure Dan Mahoney Reserve remains safe.
