2.2 Extractive industry

2.2.1 Industry considerations

The study area contains extensive deposits of both hard rock and sand resources of sub-regional significance, identified as Key Resource Areas (KRAs) in State Planning Policy 2/07Protection of Extractive Resources (Issues and Options Paper, p.8). Each KRA containsthree elements – a resource/ processing area, a separation area and an associatedtransport route where a link is needed from the resource area to a major road or railway.

As discussed in the Issues and Options Paper, extractive industries in the Jacobs Well (KRA65 - sand) and Staplyton (KRA 69 - rock) supply a market area comprising the southern partof Brisbane and Logan cities, the Redland City and most of the Gold Coast.

The study area is a primary source of supply for the sub-region, and it is critical it continuesto supply a large proportion of the demand from the identified market areas, and that theresource is protected from the long-term future use.

Given that the location of the KRAs and required buffer areas have already been mapped,the main consideration for selection of sites for extractive industry lies in determining thestrategic sequence of sites to be developed.

As such, the site selection priority should be based on consideration of the following:

the amount of resources and need for such resources

potential to consolidate the impacts of extractive industry by ensuring that future permitsoccur adjacent to existing permits. This also results in larger voids with increasedpotential to accommodate a range of post-extraction recreational or industry activities

potential to avoid any conflict with existing or committed incompatible land uses

potential to minimise impact on GQAL.

Given that distribution of hard rock deposits within the study area is confined to two locationsthat have been approved or are adjacent to existing hard rock quarry operations, this studyconsiders potential sequencing for extraction of sand resources only.

2.2.2 Site selection criteria

Primary criteria:

Key Resource Areas (as identified in the State Planning Policy 2/07 mapping).

Secondary criteria:



resources contained are currently in demand and available in quantities for economicallyviable extraction

potential to consolidate extraction in proximity to existing permits

potential to minimise impact on Good Quality Agricultural Land Class A

access to primary road network

access to haulage routes of sufficient capacity.

Desirable criteria:

potential to support transition to post-extraction uses.

Supporting infrastructure requirements:

water supply

power supply.

The following table outlines major considerations, issues and options associated with eachselection criterion.

Table 2-3: Selection criteria for extractive industry


Primary criteria

Key Resource Areas (KRAs)KRAs identified in State Planning Policy 2/07 as shown onMap 3.3 in the Issues and Options Paper indicate theexistence of a suitable sand resource.

Secondary criteria

Access to primary road network

Preference for access to existing infrastructure.

Mapping layers:

primary road network.

Access to haulage routes ofsufficient capacity

Preference for access to existing infrastructure and identifiedhaul roads. Alternatively new routes must be assessed forpavement strength, road geometry and intersection capacity tocater for dump trucks .

Potential to consolidate theimpact by locating adjacent toexisting permits

Mapping layers:

current extraction permits.

Avoid or minimise impact onGood Quality Agricultural Land,Class A

Preference to ensure extraction commences on areas GQALclass B prior to extraction from sites located on GQAL class A.

Mapping layers:


Desirable criteria

Potential to support transition topost-extraction uses

Extraction sites may be succeeded by recreational (i.e.boating, motor sport) or marine industry use. For example,outdoor recreation represents one option for transitional use ofsand extraction sites, utilising the post-extraction landscapefeatures, such as dams. Accordingly, consideration should begiven to a long term strategy of sequencing extractive sitesthat would allow linking ponds to form lakes suitable foroutdoor recreation.



The following table outlines considerations for infrastructure requirements for extractiveindustry.

Water supply There is minimal requirement for portable water to supply staffamenities and this could be obtained from rainwater tanks.

Power Preference for access to existing infrastructure.

2.3 Sport and recreation activities – motor sport


The development proposals for motor sports fall into two distinct categories: land and waterbased. As outlined in section 3.3.1, the study area provides the opportunity for potentialreuse of the water filled voids left from extractive industry operations for water-based sports,including water-based motor sports, providing noise and water quality issues can be properlyaddressed. This study focuses on land-based motor sports for which there is a specificcurrent demand as described below.

Land based motor sport will provide recreation opportunities for 2 and 4 wheeled vehicleuses that require separation from incompatible land uses due to noise and/or dust impactsgenerated by the activities. Gold Coast City Council has identified a number of communitymotorsport facilities (i.e. operated by not-for-profit, volunteer-based organisations) thatrequire relocation due to urban encroachment on sites that were previously remote fromurban development. These facilities include:

Motocross facility at Reedy Creek

Motocross facility at Yatala

Speedway and Flat Track facility at Arundel

Kart racing club recently displaced from their track at Coomera.

In total there are currently nine community motorsport clubs within the Gold Coast area,auspiced by the Gold Coast Motorsport Association.

Community motorsport clubs require a location that can be protected from future urbandevelopment and incompatible land uses, whilst ensuring the acoustic amenity of existingresidents. In addition to relocation of existing facilities, provision for future growth andexpansion is also required.

The preferred outcome identified by GCCC is the establishment of a community motorsportprecinct that can accommodate a number of clubs and activities within a single, large site.This will maximise community benefit from investment in social infrastructure and limit thenumber of residents adversely impacted by motorsport activities across the city.

The land and facility requirements for different motorsport activities vary greatly, from sealedcar parking areas for static displays to use of road networks for touring and rallying.Generally between 1ha to 6ha of land is required for individual track-based activities. Forexample, based on current and historic track provisions on the Gold Coast:



a speedway track requires approximately 1.2ha

go-karting tracks and flat tracks can be accommodated in approximately 2ha to 3haeach

motocross tracks require 2ha to 4ha

a Khanacross car rally track could be accommodated within approximately 5ha.

These estimates are for the actual track areas only, exclusive of ancillary support areas.Actual track space is dependent on a range of site specific considerations that impact onlayout and design.

In addition to track space, a community motorsport precinct will require space for:

pit areas and vehicle parking for the unloading/ loading of bikes/ karts/ cars. Mostparticipants transport their vehicles in vans, utes or on trailers;

emergency vehicle access

marshalling of vehicles prior to races

car parking for participants and spectators of regular weekly activities plus overflowspace for larger events and competitions

separation of vehicle and pedestrian movement zones

club facilities and amenities

safe spectator viewing areas

water storage such as detention basins to meet watering requirements for dustsuppression. Alternately a water supply is required

stormwater quality management and pollution control areas

buffering to ensure the ongoing acoustic amenity of surrounding land uses (especiallyresidential dwellings).

The nature of surrounding land use dictates the space required for effective buffering,where:

proximity to other noise generating activities (e.g. major roads) provides a noiseenvironment more conducive to locating motorsport activities

industrial buildings and warehouses can provide excellent acoustic buffering

varied topography that provides barriers, hills or mounds is useful and allows for costefficiencies in providing additional sound attenuation barriers

flat land with little change in terrain requires greater separation between the noisegenerating activities and receiver locations (i.e. residential dwellings).

In that regard, GCCC has identified land requirements of approximately 60ha to 150ha tolocate a community motorsport precinct, depending on the specific site characteristics andnature of surrounding land uses. Sites in the North East Gold Coast Study area have thepotential to meet these requirements, pending detailed design considerations.

There are currently two significant motor sport facilities in the study area. These are theHolden Performance Driving Centre at Norwell and the WRX Experience facility at Pimpama.In addition, there is a current proposal for a major multi-function development (the iMETTproject) that includes, among other uses, an international standard 6.5 kilometre motor



racing circuit and an international motor racing museum. The iMETT project was designatedas a significant project in February 2008 and is a subject to a separate evaluation process(i.e. the iMETT project is not considered in this Site Selection and Infrastructure Study).Should the iMETT project be approved, there may be opportunities to co-locate a communitymotor sports precinct either within or adjacent to the iMETT development.

2.3.2 Site selection criteria

Primary criteria:

minimum site area of 60 hectares

existing access to primary road network

avoid proximity to residential development (a minimum buffer 1 km separation fromincompatible uses).

Secondary criteria:

Power supply Preference for access to existing infrastructure.



2.4 Sport and recreation activities - outdoor recreation


Outdoor recreation activities, such as bushwalking, mountain bike riding, fishing andcamping, and model clubs provide valuable social and economic development opportunities.However, these activities are often difficult to locate in urban or near-urban areas due tocompeting land use objectives.

The study area provides an opportunity to accommodate the growing need for suitable landfor outdoor recreation in the region (Issues and Options Paper, p.67). This would alsoprovide economic development opportunities for the area.

Suitability of sites for outdoor recreation purposes is largely based on availability of particularlandscape characteristics that would act as an attraction or would facilitate particularrecreational pursuits (e.g. a water body suitable for water-based recreation).

Landscape characteristics within the study area with potential for outdoor recreation includewaterways and water bodies natural and constructed (e.g. former sand dredging sites),former extraction sites, and areas providing natural settings for low impact activities such ascamping, horse riding and bushwalking.

The table below identifies opportunities for different types of outdoor recreation that could belocated within the North-East Gold Coast study area.

Non-motorised low impact recreational activities are often opportunistically located based onavailability of particular attributes or natural features, and availability of such land forrecreational pursuits based on land tenure and ownership.

Location of motorised activities is more constrained, and must take into considerationspecific impact mitigation and land use compatibility requirements associated with eachactivity. The following identifies criteria for selection of sites suitable for motorised outdoorrecreation.



2.4.2 Site selection criteria – motorised outdoor recreation

Primary criteria:

attraction for recreation activities:

an existing water body suitable for motorised recreation (water-based)

land terrain suitable for trail bike riding (land –based)

existing access to primary road network

avoid access through residential areas

compatibility with surrounding land uses

avoid residential areas

for motorised outdoor activities, such land uses as water bodies, open space, ruraluses and industry are considered preferred surrounding land uses.

Secondary criteria:

flooding hazard management

avoid or minimise impact on GQAL.

Desirable criteria:

potential to utilise a former extractive industry site.

Infrastructure requirements:

Infrastructure requirements for outdoor recreation would vary depending on the type ofrecreation activity:

water supply (on-site)

waste disposal (on-site)

Part 2 – Study outcomes

3. Site selection outcomes

3.1 Marine industry

3.1.1 Site options

Given limitations associated with access to navigable waterways and availability of un-constrained land (i.e. the majority of the coastline is unsuitable for development due tomultiple environmental values, refer Figure 3-1: Site options: marine industry), optionsfor establishment of a new marine industry precinct within the study were limited to:

expansion of the existing marine precinct in Steiglitz

potential for future establishment of a new marine precinct on an approved sandextraction site at the mouth of Logan River.

Table 3-1(below) summarises the comparative assessment of the two site options.

Table 3-1: Comparative assessment of options – marine industry

Site selection criteria Site A – expansion of Steiglitzmarine precinct

Site B – establishment of a newmarine precinct on Logan River

Primary criteria

Required area No concern

Up to 83 ha (stage A, B and C), withfurther potential to expand inland up to

additional 93 ha (stage D).

Some Concern

50 ha (Stage A), potential for furtherexpansion up to a total of 88 ha intoKRA 65A1 (Stage B). However onlya small part of the site is likely to beavailable for development for marineindustry purposes following extractionof the sand resources. Therefore this

site would not provide the requiredminimum site area.

Access to navigablewaterways

No concern

The site provides access to the MainChannel North (primary navigable

channel).

Following the extractive operation,potential exists to develop an additionalchannel that would provide direct water

access for inland sections of theproposed precinct (Stages A and B).

Some concern

The site has direct access to asecondary navigable channel.

However, further studies are requiredto confirm that required width and

depth of this channel is achievable inthis location. Impact of channel

dredging on environmental values oftidal wetlands, fish habitat areas andRAMSAR sites in this location would

require further investigation.

Located outside of areascommitted to incompatibleland uses

Some concern

Stage B, C and D are located withinKRA 65 A2. Extraction of KRA

resources should be required prior tomarine precinct expansion.

No concern

Stage A is proposed on site of currentextraction

Stage B would occur once the fullextraction of KRA 65 A1 is completed

Secondary criteria



Flood velocity Some concern

The velocity of flooding waters in thislocation could be reasonably managedthrough provision of a water channel to

divert flood flows.

Significant concern

Development of a marine precinct inthis location is significantly

constrained by strong currents. Thecondition is exacerbated during

flooding events.

Avoid or minimise impactson GQAL

Some concern

The site is partially located on GQAL

(class A (122ha) and class B (0ha))

No concern

A minor section of the site is locatedon GQAL.

(class A (0.05ha) and class B(1.6ha))

Access to existing roadnetwork

No concern

The site has an existing access toprimary road network. Potential existsfor upgrade of the roads to required

capacity.

No concern

The site does not currently have anexisting access to primary road

network. However, required roadaccess will be established to support

sand extraction operation.

Potential to minimise furtherimpact on environmentalvalues of adjacent areas

No concern

Potential expansion adjoins existingdevelopment. Specific environmentalmanagement plans would be requiredto ensure impacts on environmental

values of adjacent areas are minimised.

Significant concern

This site contains tidal wetlands.Specific environmental management

plans would be required to ensureimpacts on environmental values ofthese areas are minimised. Impactassociated with waterway channeldredging on marine environment

would require detailed assessment.

Desirable criteria

Potential to minimise landtake (e.g. re-use of a formerextractive industry site)

Some concern

Establishment of a marine precinct isproposed following sand extraction on

part of this site. However the land takeassociated with this option is still up to176 hectares (including the long-termsexpansion area west of Cabbage Tree

Point Road).

No concern

Establishment of a marine precinct isproposed following sand extraction in

this location

Potential for expansion of anexisting precinct

No concern

This site is an expansion of an existingmarine precinct

Some concern

A marine precinct at this location willbe developed in isolation from

existing marine industry precincts

Potential for siteamalgamation

No concern

The proposed expansion involves alimited number of lots (<10), with some

groupings of lots being in singleownership.

No concern

The site is an existing sand miningsite in single ownership

Proximity to potentialworkforce

Some concern

The site is not located in proximity to alarge potential workforce although it is

located adjacent to the village ofCabbage Tree Point.

Some concern

The site is not located in proximity topotential workforce



Expansion of the Steiglitz marine precinctFigure 3-3 provides an indicative location of the proposed expansion of the existing marineprecinct in Steiglitz.

This site provides access to a primary navigation channel, the Main Channel North, with theplanned channel dredging depth of 2.5 metres and channel width of 40 metres9.

The proposed option would see existing marina expanding north to Cabbage Tree PointRoad, and west to KRA 65A2 over four stages. It is noted that any extension to the south ofthe existing marina is constrained by multiple environmental values associated with tidalwetlands.

Initial expansion is proposed north of the existing precinct to Steiglitz Road (stage A) and,further to Cabbage Tree Point Road (stage B). It is proposed that stages A and B wouldaccommodate major marine activities such as ship building and maintenance, and boatstorage. The proposed extension (stages A and B) would provide some 67 hectares of land(gross area) for marine industry. This would supply some 46 percent of the identified shortfallof marine-zoned land (144 ha) on the Gold Coast. The remaining shortfall could be achievedthrough further expansion west of Cabbage Tree Point Road, to KRA 65A2 (stage D – up toan additional 93 ha).

Stage C, north of Cabbage Tree Point Road, is proposed to largely accommodate a waterchannel, with some low impact urban uses adjoining existing residential precinct. Thechannel would provide waterway access to the proposed marine precinct, as well asfacilitate the floodwater flows from the north-west (Figure 3-2 indicates stronger flows in thislocation). A water channel in this location would also provide a visual and spatial separationbetween intensive marine industries to the south (stage B) and existing residential precinct.

It is noted that stages B, C and D include sections of the KRA 65A2 buffer area and minorsections of the resource area. Timing of resource extraction at this location should be co-ordinated with the expansion of the marine industry precinct, with the extractive operationcommencing to accommodate the marine industry expansion.

Finally, the site is located on land classified as GQAL class A. Given identified shortfall inmarine industrial land on the Gold Coast and limited availability of suitable land elsewhere, itis suggested that marine industry uses should take precedence.

In summary, opportunities provided by expansion of Steiglitz marina include:

required area

potential to provide direct access to navigable waterways for the majority of the site(stage A and stage B)

potential to expand an existing industry cluster

high potential for site amalgamation

future potential to minimise land take through utilising an extraction industry site, onceextraction is completed (stage D).

9 Gold Coast Waterways Access Needs Study, GHD, work in progress data, 2008



Some minor concerns associated with this site include site’s location on GQAL and lack ofaccess to local workforce. There are no major constraints for establishment of a marineindustries precinct associated with this site.

Logan River marine precinctPotential for future establishment of a marine precinct on a sand extraction site at the mouthof Logan River was considered.

This site provides access to a secondary navigation channel on Logan River. It is noted thatthe channel is characterised by sections of a narrow channel width (less than 20 metres)and is affected by strong currents. Acceptable dredging parameters for this channel are yetto be investigated10.

The existing sand extraction permit covers some 50 hectares, with total potential forexpansion in this location being in the order of 88 hectares. However following sandextraction the site will comprise predominantly large water-filled voids with relatively limitedland available for marine industry purposes.

Opportunities presented by this location include:

direct access to navigable waterways

potential to minimise land take via re-use of a former extractive industry site

high potential for site amalgamation.

The lack of local access to potential workforce is one of concerns associated with this site.

Major identified constraint associated with this site is the great velocity of floodwaters (referFigure 3-2) that would require implementation of considerable mitigation measures to ensuresafe operation of marine industries in this location. Feasibility and effectiveness of suchmeasures would require detailed investigation. In addition, the waterway channel providingaccess to the site contains sections requiring significant dredging to achieve acceptablewaterway width and depth. Given multiple environmental values associated with thiswaterway channel (i.e. Ramsar sites, tidal wetlands and fish habitat areas, refer Figure 1-2),detailed assessment of environmental impact of dredging in this location would be required.

Finally, the site contains areas of tidal wetlands. Potential for marine industry to impact onthese environmentally sensitive areas is another consideration rendering this location lessfavourable for establishment of a marine industry precinct.

However, subject to appropriate resolution of these concerns the Logan River site ispotentially suitable for a range of marine infrastructure or water-based recreation usesincluding recreational boat marina, working (grey boats e.g. barges and dredges) boatmarina, and a limited amount of marine industry and other support activities.

10 The navigation channel on Logan River is not included in the current Gold Coast Waterways access needs study, GHD, work inprogress, 2008.

3.2 Extractive industry

3.2.1 Site options

Table 3-2 provides details on estimated demand for the study area’s sand resources. Itshows that cumulative demand to the year 2031 is estimated to be in the order of22,000,000 tonnes. At the assumed sand depth and density, this demand would involveextraction from resource area of 130 hectares. Table 3-3 demonstrates that unminedreserves adjacent to existing mined permits at Jacobs Well (KRA 65 B) and Woongoolba(KRA 65 A1), and reserves associated with future expansion of Steiglitz marine precinct(KRA 65A2, selected sites) comprise 265.57 gross hectares, which is in excess of theestimated demand to 2031. Figure 3-5 provides location of lots referenced in Table 3.3.

The gross hectares must provide not only for the area of extraction but include buffers andaccess. That is, some of the lots shown in Table 3-3 may be completely consumed tomining operation, whereas other lots would, partly or wholly, provide for buffers, facilities andaccess. The available area of 265.57 hectares is double the area that would be consumedbased on the assumptions contained within Table 3.2 and, therefore, provides conservativelyfor the anticipated consumption of the resource over the next 23 years.

Additional considerations for sequencing of sand extractive precincts include the following:

potential to consolidate the impacts of extractive industry by ensuring future permitsoccur adjacent to existing permits.

Additional advantages of this approach include potential to develop a strategy forrehabilitation of extractive sites for outdoor recreation purposes (i.e. dredging basins couldbe sequenced so as to provide potential to form a larger basin for a contiguous lake).

potential to minimise conflicts with existing and committed land uses and values.

For example, where there is a conflict between the need for extractive resources andpreservation of GQAL, sequencing of extraction sites should take into consideration grade ofagricultural land, with GQAL class B (poorer quality) to be developed prior to GQAL class A(superior quality) sites.

KRA 65 A1 contains sections of land classified as GQAL Class A (0.05ha) and Class B(1.6ha), KRA 65B contains sections of land classified as GQAL Class B (78ha). Sections ofKRA 65 A2 associated with the expansion of Steiglitz marine precinct contain land classifiedas GQAL Class A (24 ha):

potential to reuse a site for other uses once extractive industry ceases to operate.
