Judy Holt Park

Environmental rehabilitation works

Judy Holt Park, once a landfill, is one of 28 areas on the Redlands Coast repurposed into green spaces for the community.

Historical landfill practices predating stringent environmental laws mean Council must now effectively manage this legacy inherited to us. In particular, we are focussed on the management of leachate, water that has passed through waste material in a closed landfill and picked up contaminants on the way.

Council has already made significant progress, such as capping the eastern part of the park with an engineered system to minimise water penetration. 

Upcoming works to the northern section of the park include reshaping the northern slopes, installing ventilation systems, expanding the existing leachate management system, and enhancing monitoring protocols. These works are being undertaken to protect nearby ecosystems like Tarradarrapin Creek, which flows into RAMSAR-listed wetlands.

Supported by the Department of Environment, Science and Innovation (DESI), these ongoing efforts aim to safeguard the surrounding environment by preventing the movement of residual liquid.

Current works snapshot (from 2024–2026)

The planned works to the northern section of the park aim to safeguard the environment by preventing residual liquid movement. Council will undertake the following: 

• reshape northern slopes
• add ventilation systems
• expand existing leachate system
• enhance monitoring protocols.       

During works, the community can expect:

• construction hours: Monday–Saturday 6.30am–6.30pm (work is subject to weather conditions and other unforeseen circumstances)
• moderate levels of noise and dust, managed through appropriate mitigation measures
• temporary access restrictions in certain areas for safety reasons
• no restricted access to the playing fields
• fencing and signage in place to prevent park users from entering the construction area.      

Vegetation clearing and rejuvenation

The removal of vegetation at Judy Holt Park has been completed.
  
Purpose: This step was essential to facilitate necessary works for long-term environmental rehabilitation.

Evaluation and compliance:

•   Vegetation removal was based on a thorough environmental assessment report.
•   Strict codes and regulations were followed, with only essential areas approved for clearance.

Environmental outcome: A significant portion of the removed vegetation consisted of introduced species and weeds. The removal of such vegetation is expected to positively impact the area.

Reason for clearing:  The vegetation was cleared due to inappropriate regrowth on the landfill cap base.

Next steps:  With the vegetation removed, the project team can now access the affected areas to clean up and build the necessary infrastructure for leachate control.

To ensure clarity on the project progress, Council has updated the vegetation clearing map displayed. The updated map provides a detailed view of the areas where vegetation has been cleared. 

 

Rugby field upgrade information

Council is upgrading the rugby fields at Judy Holt Park to improve facilities for the community.

Current vs. new

A concept sketch showing the proposed new field layout is below. This sketch helps illustrate the planned changes. Please note that this is a preliminary illustration intended to provide a general overview of the planned changes. Final designs may vary.

Project schedule

(Above: Judy Holt Recreation Reserve rehabilitation works map)

Stage 1 (green): design and construction late 2024–mid 2026

• Leachate collection trench & access road
• Pump station

Vegetation clearing has occurred primarily on the fringes of the green shaded area, with the exception of a few trees that have regenerated on the slope of the batter near the white stage 2 area.

Stage 2 (white): future works mid to late 2026 

• Capping of rugby fields (late 2026)

Post-Completion (2026-2028):

• Compliance monitoring by suitably qualified person

Existing capped area (blue): 60% of this area has been successfully remediated.

Frequently asked questions

Why are the wetlands near Judy Holt Park significant?

The nearby Tarradarrapin Creek runs into the Ramsar listed Tarradarrapin Wetland. These wetlands are vital for biodiversity, water quality, and habitat preservation. They act as natural filters, support diverse plant and animal life, and mitigate flooding. Protecting these wetlands is essential for ecosystem health and the well-being of both wildlife and the community.

What is a Ramsar Wetland?

In 1971, representatives from 18 nations including Australia met in the Iranian city of Ramsar to sign the Convention on Wetlands of International Importance, known as the Ramsar Convention. The Ramsar Convention aims to stop wetlands being lost across the world, and to conserve and manage the remaining wetlands we have.  Wetlands support large numbers of waterbirds and/or threatened species, exhibit other biodiversity or have unusual and precious landscapes. The convention lists wetlands that are so valuable they are considered international treasures. Queensland has five wetlands listed by the Ramsar Convention. 

What is Council doing to protect the environment and in particular Tarradarrapin Creek?

Stringent environmental guidelines underpin the planning, design and delivery of this project and Council is committed to meeting all its environmental responsibilities. The prime environmental objectives of this project are to reduce the migration of leachate off site and reduce its generation.

Why was vegetation clearing necessary for this project?

Vegetation clearing was necessary to access and remediate contaminated areas, ensuring the protection of wetlands and surrounding ecosystems. Care was taken during detailed design to minimise the number of trees removed, but it was not possible to achieve the required environmental outcomes and retain all the vegetation. Council has pledged almost $200K to offsite planting and rejuvenation efforts adjacent to the Koala Bushland Coordinated Conservation Area at Mount Cotton.

How will the project benefit the community in the long term?

The project will have numerous long-term benefits for the community, including improved water quality, enhanced recreational opportunities and preservation of biodiversity. By safeguarding the wetlands, we are investing in the health and well-being of both current and future generations.

What is a closed landfill site?

Closed landfill sites are locations where household and industrial waste has been buried. 

What is leachate?

Leachate is water that has passed through waste material in a closed landfill and picked up contaminants on the way.

What research and analysis informed Council decision making at Judy Holt Recreation Reserve?

Council monitors the water and air at Judy Holt Park by regularly sampling from: 

• 16 ground water wells, 11 leachate monitoring wells and 5 surface water sampling sites, and gas wells, vents, site structures and the ambient air.

This data has informed an Impact Assessment and a Mitigation Strategy, which was developed in partnership with an Environmental and Engineering Design Consultant who:

• reviewed the site conditions and monitoring data
• prepared a report highlighting any gaps in this data and knowledge
• undertook any fieldwork or monitoring to close the data gaps
• prepared a draft Contamination Land Investigation Document (CLID) which has been reviewed by the Contaminated Land Auditor (CLA).

This work has been reviewed independently by a contaminated land auditor to ensure it is appropriate.

What is a Contaminated Land Auditor (CLA)?

In Queensland, an auditor for contaminated land independently evaluates a contaminated land investigation document and prepares an auditor’s certification of the document.

The government then relies on the auditor’s certification to determine what action should be taken regarding the contaminated land.

Approval to be an auditor in Queensland is a legal status that can only be granted by the chief executive of the department administering the Environmental Protection Act 1994, which currently is the Department of Environment Science and Innovation (DESI). Without that approval, a person cannot act as an auditor.

What is a site Management Plan (SMP)?

SMPs are used to manage the environmental harm that may be caused by contamination of land. 

In many instances it is more practical and presents less environmental and/or health risk to manage contaminants on-site under specified conditions rather than trying to remove them. These conditions would form the basis of a SMP. 

SMP's must be approved by the Queensland Environmental Regulator before taking affect. 

What works are typically required to make closed landfill sites safe for us and the environment?

The work required depends on the type of waste that has been deposited, the sensitivity of the receiving environment and if there is an evidence that contaminants are leaving the site.

How are old landfill sites regulated?

Landfill sites in Queensland are regulated by the Queensland Department of Environment Science and Innovation (DESI) through the Environmental Protection Act 1994 (EPA).

What work has already been done at Judy Holt Recreation Park?

The Eastern part of the site has been capped with an engineered capping system, which is designed to minimise the penetration of water. Other infrastructure includes a leachate collection trench and pump station. The leachate collected from the Eastern part of the site is sent to the Capalaba Wastewater Treatment Plant for treatment.

The works won’t be completed for five years so what is happening in the meantime?

Council has an inspection and maintenance regime in place, including an Incident Response Plan for management of any leachate outbreaks should they occur. While the northern section of the site does not have an engineered cap it does have a cap to reduce infiltration and ensure waste is safely buried to create a valuable community space.
