Barton Park Recreational Precinct upgrade project

The Project

The upgrade of Barton Park in Banksia will provide an open space along the Rockdale Wetlands Corridor. Walking and cycle connections will offer growing populations in Arncliffe, Banksia and Wolli Creek access to a variety of recreational activities, including organised sport, family outings, bird watching, and environmental education opportunities.

Generally, the works proposed will consist of:

• 4 sporting fields

• 4 tennis courts

• 2 multi-use courts

• Training field

• Play space

• 4 carparks (totally approximately 241 car spaces)

• Football and tennis clubhouses and amenities

• Fitness park

• Walking / cycling pathways

• Other associated infrastructure

The Challenge

A Preliminary Environmental Assessment concluded that the site was used for various activities that caused contamination, including use as a sewerage farm and a landfill. The study area once operated as a landfill between the 1940s-1980s, when it was then capped and utilised as a recreational open space.

The landfill was constructed without engineering controls to manage leachate or gas impacts and was not formally capped. Therefore, Contaminants of Potential Concern (CoPC) were present onsite. There was potential for environmental impacts during the construction process and operations associated with contaminated soils such as transportation of dust, generation of asbestos fibres, exposure of waste material and contaminated groundwater and sedimentation and runoff from contaminated spoil stockpiles. However, such impacts are likely to be mitigated through strict soil and erosion measures.

Our Solution

Overall, the identified potential environmental impacts associated with the proposed works were adequately managed by adhering to the design recommendations and mitigation measures outlined in the ecology reports.

The designer and contractor utilised a HI VIS geotextile to act as a warning layer. Our ProFab® AS140/Orange indicator geotextile is designed to delineate potential areas of hazard when excavating potentially contaminated ground or in the positive identification of buried services. The demarcation layer conducts the same filter and separation functions as the range of ProFab® nonwoven geotextiles, with the additional benefit of high visibility to warn contractors during future excavations of the contaminated soils beneath.

Over 50,000sqm ProFab marker layer was used to visibly separate clean and uncontaminated soils. The variety of roll widths available made this product cost effective and easy to apply.
