What works are required to prepare Shorten Reserve for ground improvements?
- Shorten Reserve sports field is located within a former bluestone quarry, which later became a landfill site.
- This playing field is located on material that is unstable and results in the uneven ground.
- These undulations present challenges to users and to ground maintenance staff. This is why we are undertaking significant ground improvement works to upgrade the sports field.
- To improve the ground conditions at this site, compaction is required to prepare a foundation that is suitable to rebuild a quality sports field at Shorten Reserve. Compaction includes adding additional soil and pressing it down to make the playing field more stable.
What is the methodology for site compaction?
- The method of compaction is to use a heavy roller, which is a large construction vehicle/plant designed to compact earth. This, in combination with the placement of additional soil (surcharge), has been selected as having the least possible impact on surrounding residents.
- This vehicle will drive across the field with a roller to compress the surface.
- In addition to the heavy roller, field compaction will be achieved using imported surcharge. Approximately 1.5 metres of clean soil will be placed on the field, and the weight of the material will drop the playing surface beneath it by 0.5 metres over a 12-month period.
- Once complete, the material will be removed to expose a suitable base that will be used to reconstruct a sports field on.
What is the ground works schedule?
|
Remove and stockpile the topsoil from Shorten Reserve for reuse. This involves digging just the top 150mm of topsoil.

What are the details of the surcharge installation process?
- Surcharge will be brought to the site entering from Market Street via Barkly Street.
- After the soil has been in place for 12 months, trucks will be required to remove the material.
- These works will be delivered in accordance with EPA guidelines and the construction management plan. As such, dust mitigation measures are planned with the use of grass coverage across the entire site.
- The delivery and placement of surcharge will commence in December
- Any material imported to Shorten Reserve for compaction works will be clean material.
What are the details of the compaction rolling process?
- The roller will begin works in the centre and progressively move closer to the site periphery.
Is there a risk of damage to surrounding properties?
- There is no risk of property damage as council will be using a conventional heavy rolling method & surcharge.
- Council will not use the impact roller due to the ground disturbances that it causes.
What if I remain concerned about damage to my property but my property is not within the area for dilapidation reporting?
- All properties within the quarry zone have been invited to undertake a dilapidation assessment to document the condition of their property before works begin. This has been undertaken as a precautionary measure only.
- Property owners located outside the quarry footprint are welcome to undertake their own dilapidation assessment for peace of mind.
What are the white sheets that have been applied over the field?
A number of particularly soft areas have been revealed throughout the earthworks phase. These areas are unable to achieve the compaction results required to reconstruct the sports field. Geo textile fabric has been applied to these areas before being covered with rock and soil. This method is commonly used to stabilise ground conditions for a sports field.
What is the orange layer being applied across Shorten Reserve this week?
As outlined in the details above, imported soil is applied to Shorten Reserve to compact the field and achieve the designed surface level.
An orange layer of geofabric material is being applied to the field to separate the two different imported soils types.
Soil placed above this material will be removed before reconstructing the field.
