Gasworks Arts Park is a green oasis in the urban setting
where the past is celebrated, the future is anticipated and
our culture has a living presence.
vision statement

4
1. Promote the development of an accessible vibrant community hub.
2. Respect and celebrate the park’s story.
3. Support the expression of arts and culture within the park.
4. Create a range of landscape zones that support a variety of experiences and activities.
5. Develop and manage the park in a safe, sustainable, and inclusive manner.
guiding principles
DRAFT GUIDING PRINCIPLES
5
Vehicle access into the park – impact to design of park
Considerations
1. Pedestrian safety
2. Vehicle movement maintenance impact within the park
3. Vehicle impact on surrounding streets
4. Heritage considerations
5. Access for Gasworks theatre and market
6. Impact on future location of playground
7. Planning considerations
8. Traffic considerations and technical constraints
9. Impact on design of soil remediation works Vehicle access 7
Vehicle access options
Pros• Vehicles constrained to one end of the park • Reduces pedestrian conflict through the park• Eliminates trucks on Foote and Richardson Street.• Removes pedestrian conflict at Café• Minimises cut zone for soil capping/remediationCons• New vehicle crossing point
Option 1
Option 2
Vehicle access8
Pros• Vehicles constrained to one end of the park • Reduces pedestrian conflict through the park• Eliminates trucks on Foote and Richardson Street.• Location of play space is flexible Cons• Vehicles move beside the café where there is a
high concentration of pedestrians.• New vehicle crossing point
Cons• Vehicles drive through park increasing rick of conflict
with pedestrians• More remediation/ maintenance of grassed surfaces
and edges.• Trucks on Richardson Street
Pros• Vehicles constrained to one end of the park – easier
to manage.• Reduces pedestrian conflict through the north east
end of parkCons• Increased conflict point at Foote Street and along
access route• Increases truck traffic onto Foote and Richardson
Streets.• Potential conflict with play ground location

Impact to park and responsibilities
Soil remediation – impact to design of park
Priorities, responsibilities and considerations
1. Councils first priority is to ensure a safe place for the community.
2. Council needs to ensure that the future management and
maintenance of the park will be clearly defined and managed.
3. Council will prioritise returning the park after remediation works in a state that maintains its current functionality
capping options 22
1. Capping of half a metre of clean soil on top of contaminated soil (mounding)
2. Removing half a metre of contaminated soil and replacing it with half a metre soil (cut and fill)
3. Geofabric layer covered with lesser thickness of clean soil
4. Capping contaminated soil with hard paving/impervious surfaces
5. Interventions that cause a separation of the soil from users. (eg boardwalks/ fencing)
CAPPING OPTIONS
capping options 23
1. Capping with half a metre of soil
capping options
Benefits Challenges Good separation from contaminated soil Changed ground levels
Can plant trees anywhere Need to remove existing trees
Reduce ongoing management
24
2. Cut and fill
capping options
Benefits Challenges Good separation from contamination Ongoing management
New landscape features Limited vegetation
Maintains levels to connect with surrounding infrastructure
Identify contaminated soil retention areas
25
3. Geo-fabric layer
capping options
Benefits Challenges Good separation with contamination Limited vegetation
Reduced level change Ongoing management
26
4. Hard paving
capping options
Benefits Challenges Solid separation with contamination Hard surface - concrete
Low ongoing maintenance and management Contributes to Urban Heat Island Effect
Connects with buildings of park
27
5. Boardwalks and fencing
capping options
Benefits Challenges Retain existing large vegetation Infrastructure intensive - $$
Good separation from contamination May impact vegetation
Landscape feature Ongoing management – what happens when the tree dies?
No guarantee of vegetation survival
28
Soil remediation methods – benefits summary Capping contaminated soil with 500 mm of clean soil
Removing 500 mm of contaminated soil and replacing it with 500 mm clean soil
Geofabric layer covered with a lesser thickness of clean soil
Capping contaminated soil with hard paving/impervious surfaces
Interventions that cause a separation of the soil from users. (eg boardwalks/ fencing)
Benefits •Good separation from contaminated soil •Can plant new trees anywhere •Reduce ongoing management
•Good separation from contamination •Maintains levels with surroundings •Reduce ongoing management •Limited vegetation •New landscape features
•Good separation with contamination •Minimised level change •Some trees can be retained
•Solid separation from contamination •Low management impact •Low maintenance of surfaces •Provides interfaces to buildings
•Retain existing large vegetation •Good separation from contamination •Landscape feature •May impact vegetation
Constraints/ drawback
•Need to remove existing trees/ vegetation •Changed ground levels
•Relocate on-site contaminated soil retention areas •Need to remove existing trees/ vegetation
•Create pockets of contamination when trees die •Vegetation roots may penetrate fabric •Difficult to establish new vegetation •No guarantee of existing vegetation survival
•Contributes to Urban Heat Island Effect •Impacts the character of the park if used moderately-extensively
•Significant cost implication •Significant maintenance and management implications •Create pockets of contamination when trees die •No guarantee of vegetation survival •May impact park character
capping options 29
The park will be significantly impacted by capping works. The major impacts will include: •Vegetation loss through changes to soil around root structures.
•Increased mounding within the site due to capping and through maintaining existing levels at egress and access points.
•Removal of vegetation.
Soil remediation – Major impacts on the park
Soil remediation 30
Mitigation options Vegetation loss through changes to soil around root structures
Increased mounding within the site due to capping and through maintaining existing levels at egress and access points
Removal of vegetation
Mitigation strategy
Retain significant trees through other separation interventions
This impact is unavoidable as it is critical to maintain these access points
Replace vegetation as part of first phase of enhancement works.
Options This option could involve building fences or structures such as board walks around trees
N/A Use larger plant stock at key points
Benefits Retains significant trees that provide major amenity and cultural value for the park. Provides new uses and features for the park
Constraints/ drawback
•Significant cost implication •Significant maintenance and management implications •Create pockets of contamination when trees die •No guarantee of vegetation survival •May impact park character
Soil remediation 31
Priority/responsibility • Councils first priority is to
ensure a safe place for the community.
• Council needs to ensure that the future management and maintenance of the park will be clearly defined and managed.
• Council will prioritise returning the park after remediation works in a state that maintains its current functionality
Recommendation 1. Recommend removal and
replacement all existing vegetation and implement best practice capping techniques.
2. An increased risk of contamination being unsafely managed provides an unfavourable option.
3. The impact on cost, maintenance and management of boardwalks and other interventions challenges Councils ability to fund the remediation and delivery of the park.
Soil remediation 32
Implementation
IMPLEMENTATION – next steps
Item
Wall bracing and monitoring (in progress)
Detailed investigation and design and tendering of works
Removal of furniture, vegetation and other elements to enable soil remediation works
Earthworks and soil remediation
Foundations and service trenching locations
Building of paths, pavements, trees, garden beds and grassed areas
Council will endeavour to return the park to its current functionality, with enhancement of areas over time.
implementation 34
Priorities for implementation Stage 1
1. Paths, grassed surfaces, garden beds, trees • The structure of the park will be implemented immediately, including
paths, access and egress points, trees and surfaces.
2. Furniture – seating, bins • Adequate seating and bins will be provided to meet the functional
requirement of the park.
3. Lighting • Initial implementation of lighting to meet key safety requirements
