GIS IN PLANNING DESIGN AND DEVELOPMENT

Introduction

Context The Greater Bendigo area is located centrally in the state of Victoria, approximately 150 northwest of Melbourne. The site is about 3,000 square kilometres and hosts 82 suburbs (Profile. id 2022; Know Your Council nd), with Urban Bendigo comprising 85% of the total population (Greater Bendigo City Council 2018). According to the latest Census data from the Australian Bureau of Statistics, there were 121,470 people residing within the region (2021). These figures indicate an increase from 110,477 residents from the last Census year in 2016 (Australian Bureau of Statistics 2016) and support projections of a

continued trajectory toward 200,000 residents by 2050 (Greater Bendigo City Council 2018). As one of the most rapidly growing councils in Victoria, alongside Geelong and Ballarat, there is an apparent necessity to provide adequate dwellings to accommodate for future population growth (Forecast. id 2022). As outlined in the Greater Bendigo Residential Strategy (2018), future growth will aim to fulfil the Compact City model, with the Council recognising previous urban development centred around uncontained sprawl and car dependency as being ‘unsustainable’ (p. 4). In line with these objectives to create a more ‘liveable’ Greater Bendigo area, this report will seek to find sites congruent with the Council’s vision of creating a more sustainable, connected and healthy Bendigo.

Literature Review

GIS IN PLANNING DESIGN AND DEVELOPMENT

Literature Review This section of the report will provide a brief overview of the guiding principles informing the future development of the Greater Bendigo municipality. Firstly by investigating several published strategic plans prepared by the council. Next, it will draw comparisons to contemporary urban theories such widely proposed in other strategic plans such as Plan Melbourne 2016-2050, which have designated Bendigo as an integral regional growth centre (Victorian Government 2016). Lastly, this section will investigate the forms of GIS-based decision-making within the Greater Bendigo City Council in recent years.

3.1 Implemented Bendigo Strategic Plans Plan Greater Bendigo (Greater Bendigo City Council 2018) and the Greater Bendigo Residential Strategy (2018) are the predominant plans informing the future urban development of the region. Subsidiary plans such as the Connecting Greater Bendigo: Integrated Transport and Land Use Strategy (2015) and Greening Greater Bendigo (2020) are also instrumental in defining the prospects of development within the area, envisioning a well-connected and healthy region for residents. The retention of the region’s reputation as a ‘City in a Forest’ reverberates strongly throughout all plans, alongside the reduction of urban sprawlcontaining development within the Urban Growth Boundary and the promotion of interconnectivity through active and public transportation networks reverberates extensively throughout.

3.2 Connection to Urban Theories

3.3 History

Common vernacular within the urban planning sphere has shifted towards agendas of improving liveability, inclusivity through community engagement and sustainability through active transportation. The principles outlined in the theories of the Compact City (1980s-1990s), New Urbanism (1980s-2000s) and the Polycentric City (1990s-2000s) have guided many contemporary planning efforts in Australia (Freestone 2010). It has been catalysed by the departure from the carcentric city model, which once dominated the post-war era of urban planning, a design which exacerbated urban sprawl through the ‘freedom of the road’ (Davison 2004). As stated within the Greater Bendigo Residential Strategy (2014), the continuation of unmanaged sprawl into the urban fringe is unsustainable for the liveability of future residents, with Council agendas in alignment with the theories above. Furthermore, there has been a shift towards ‘rebalancing’ the population of Victoria into regional municipalities such as Greater Bendigo, as outlined within Plan Melbourne (Victorian State Government 2016) and the Loddon Mallee South Regional Growth Plan (Victorian State Government 2014), which evokes the need to prioritise Greater Bendigo as a major urban development centre.

Project Objective

y of GIS in Greater Bendigo City Council

of GIS has been instrumental to urban planning since opment in the late 1960s; however Maliene et al. (2011) until the 1990s, its use was restricted mainly to industry nals due to cost and hardware constraints. The advent of gy in the 21st century has allowed GIS to become utilised ay situations such as GPS and interactive maps (Maliene 1). Greater Bendigo City Council maintains a public GIS powered by POZI, which has the ability to visualise data g to planning overlays, public amenities and up-to-date ting efforts- one of the guiding agendas of the Greening endigo strategic plan.

In order to accommodate for Greater Bendigo’s projected population growth, there is a need to provide a supply of 18,000 dwelling units in the next two decades. This amount of dwelling units approximately equates to around 1800 hectares of land. The project objective is to utilize the many tools of ArcGIS Pro to input and analyse selected data which was chosen based on the visions laid out by Plan Greater Bendigo (2018), Greater Bendigo Residential Strategy (2018), Connecting Greater Bendigo Integrated Transport and Land Use Strategy (2015) and Greening Greater Bendigo (2020). The rationale behind the selection of the five criteria will be further elaborated upon in the next section. Lastly, in order to determine the most suitable sites for future urban development, a weighted overlay will be conducted as the final process.

uced maps are often featured heavily throughout Greater City Council’s strategic plans, to provide context for the nd visualise future development opportunities (refer to & 3). However, aside from the ‘Crown Infill and 10 Minute urhood Map’ within the Greater Bendigo Residential Strategy ere has been no GIS-based land suitability analysis ed for the Council. Figure 2.

Potential towns should be located close to existing transport corridors in order to promote Transit Oriented Development principles, outlined within the Connecting Greater Bendigo Integrated Transport and Land Use Strategy (2015).

One of the components of a liveable city revolves around the resident’s access to amenities- that includes education, services and employment (City of Greater Bendigo, 2018). The potential towns should be located within close proximity of established amenity clusters.

Natural disasters are traumatic events for communities, as seen throughout history and the recent years. As Bendigo is surrounded by swathes of forest and many waterways, it is imperative to avoid areas of risk, to facilitate for a safe community as well as the mitigation of potential damage costs.

Following the collection of all required data, base maps were produced for all criteria to provide the context of the current situation. A new toolbox.atbx was created by navigating to the catalog view and right-clicking on the connected folder. Within the new toolbox, a new model was created by right-clicking the toolbox.atbx. Before starting the Model Builder process, it is imperative to set the Environments to this specific format: Import Coordinate Systems: Bendigo.shp, Processing extent: Bendigo.shp, Mask: Bendigo.shp and Cell Size: elevation. If these settings are not applied, the processing would not be accurate. Euclidean Distance was chosen as the primary intermediate processing tool, as it calculates the distance from each cell to the closest source. Features were inputted individually into the Euclidean Distance tool, with default values and run. The output raster was then resymbolised to the desired colour scheme and divided into 10 equal intervals and rounded up to round values. This output raster was then input into the Reclassify tool, into 1-10 intervals, with 1 being the most desireable value and 10 being the least. This process was repeated for every single criterion except for the BMO and LSTIO, where were assigned values of 1 (restricted) and 10 (unrestricted). This is since the BMO and LSTIO already define restricted parameters for development. Detailed processes are outlined in each of the subsections below and in the final Model Builder diagram.

Transit Connectivity The Greater Bendigo Council is relatively well served by the regional train and bus networks, with the predominant activity being centered within the Urban Bendigo area. Although bus and train stops appear disproportionately centered within the epicenter of Bendigo, this is relative to the fact that 85% of the LGA’s population resides within Urban Bendigo (City of Greater Bendigo 2018). Furthermore, major highways provide valuable connections to other regional towns and the Calder Highway provides a direct link to Metropolitan Melbourne (Google Maps 2022).

Access to Amenities Example of Predominant process Proximity to amenities is an extremely relevant criteria to consider, not only in terms of accessibility, but also employment. According to the latest avaliable Census data on employment (ABS 2016; still awaiting release of 2021 employment statistics), healthcare (16.7%), retail (11.4%) and education (8.9%) were three of the top sectors (Profile ID 2022). Amenities were more heavily distributed within the center of Urban Bendigo and established towns such as Kangaroo Flat, Heathcote

Healthy Bendigo The City of Greater Bendigo is renowned for its reputation as a ‘city within a forest’, with the Greening Greater Bendigo strategic plan setting an ambitious agenda to increase tree canopy within urban Bendigo by 45% by 2070 (City of Greater Bendigo (City of Greater Bendigo 2020). Greening has been used as a strategy to combat the Urban Heat Island effect and climate change, in order to lower temperatures catalyzed by lack of vegetated green spaces in urban settings (Hiemstra et al 2017). Furthermore, fostering a healthy community is at the forefront of Plan Greater Bendigo (2018), citing that more than 50% of adults are overweight and equivalently do not meet daily exercise requirements. The chosen criteria, comprising of access to parks, sporting facilities and walking trails were chosen in order to facilitate for the accessibility to places of active recreation in fulfillment of a healthy community.

Mitigating Risk Example of Predominant process Within the global context, Australia is one of the most heavily impacted countries in terms of natural disaster occurrences (Ladds et al 2017). Flooding events such as the 2022 Queensland and New South Wales disaster delivered extensive damage to towns, houses and claimed the lives of 22 people (CSIRO, 2022). Whilst catastrophic bushfires such as the 2019-2020 event impacted every state in Australia, burning more than 10 million hectares of land in Southern Australia alone and caused mass fatalities amongst native wildlife (CSIRO, 2020). Therefore, it is of utmost importance that bushfire and flood prone areas are avoided in choosing a suitable site, to mitigate the risk of traumatic events

Compact Bendigo Example of Predominant process The fulfillment of the ’10 minute neighbourhood’ is heavily enshrined throughout the Greater Bendigo Housing Strategy (2018), wherein residents are able to access their needs within ‘a 10 minute walk or cycle’. Furthermore, the strategy outlines the need to contain future urban development within the Urban Growth Boundary, to avoid further sprawl. As observed within the amenities section, the majority of educational facilities, health care facilities and retail is concentrated

Weighted Overlay

39

Amenities 15% Healthy 15% Risk 20% Urban 20%

This was executed by inputting every single reclassified criteria raster into the weighted overlay table and assigning each a weight percentage based on perceived importance. Proximity to transit corridors was assigned the greatest weight (30%), in alignment with Compact City and Transit Oriented Development principles. Currie and Delbosc (2010) state that transport disadvantage can greatly inhibit quality of life, access to employment opportunities and engender time poverty. Furthermore, as seen throughout the output maps, amenity clusters are often within concentrated transit corridors which would promote the values of Compact and Connected Bendigo, principles stated within the Greater Bendigo Residential Strategy (2018). Mitigation of risk (20%) was the next greatest priority, as the avoidance of bushfire and flood-prone areas should be avoided in order to ensure future residents a Healthy Bendigo, free from the potential of traumatic natural disaster events. Proximity to urban areas (20%) was also weighted identically, due to the need to limit urban development within already established towns. This is an important criteria to consider, as many of the established amenities and transit corridors are within established towns. The last two criteria, Healthy Bendigo and Access to Amenities were equally assigned 15%, as the location of these criteria already fell within established transit corridors and established urban areas.

Transit 30%

According to Chen (2016), the Boolean overlay and weighted overlay are the two most commonly used forms of GIS suitability analysis (p.50). Unlike Boolean overlay, which only presents true or false criteria, similar to the Con tool used in the BMO and LSTIO reclassification, weighted overlay provides a more nuanced approach to determining suitability as the weight percentage can be assigned individually to each criteria (Chen 2016). Therefore, in order to find the most suitable Urban Growth Areas in Greater Bendigo, weighted overlay was used.

the Urban Growth Boundary, all areas outside of the boundary were excluded by using the Clip tool. Furthermore, as urban areas are already established, the Erase function was necessary to exclude already developed attempting to select suitable urban growth areas, it was observed that some polygons were merged in large areas. To rectify this, the Multipart to Single Part tool was used to separate large, combined polygons for a more accurate selection. This final output layer was used to determine the potential urban growth areas.

After dragging the Weighted Overlay table into the Model Builder, all criteria were input. For every single criteria excluding the BMO and LSTIO, the values were reversed so that 1=10, 2=9, 3=8 and so forth. This is because when running the Weighted Overlay function, values closer to ‘10’ are more desireable, as opposed to the previous function of Reclassify which denoted the value of ‘1’ to be the most desireable. For the BMO and LSTIO weighted overlay, values of ‘1’ were restricted as these were predetermined bushfire and flood-prone areas which should be avoided.

Finally, in order to determine the Urban Growth Areas it was required to convert the Shape_Area, which was measured in units of metres to hectares instead. A new field was created and the hectares was calculated by assigning the Shape_Area as ‘area’ and the units as ‘hectares’. This would allow for the selection of the 7 largest polygons in the Greater Bendigo Area which equated to 1800 hectares and the equivalent of 18000 dwelling units.

Once run, the output map was produced and ranked values starting from ‘0’ being the least suitable to ‘7’ which was the most suitable. As the project objective is to determine the most suitable areas for development, a new layer was created by selecting values of only 7 (Refer to Figure 39). In adherence to the Greater Bendigo Residential Strategy objectives of limiting urban development to

Concluding remarks nterpretation of Final Suitable Areas: The final suitable areas equate to just under 2000 hectares of land. This excess is to accommodate for potential, unpredictable population growth as well as the further construction of additional services and amenities, such as child care and shopping centres. This is justified by the premise of the ’10 Minute Neighbourhoods’ outlined in the

Greater Bendigo Residential Strategy, wherein residents can access their daily needs within a 10-minute walk or cycle from where they live. Although the chosen Urban Growth Areas are within proximity of established transport corridors and amenities, the need may arise to implement more services to enhance convenience in the future.

Limitations of the report: Infill development The primary objective of this report was to identify potential Urban Growth Areas distinguished from already established urban areas. It foregoes the potential of implementing infill development of a medium to high density within pre-existing urban regions. According to the latest census data from the Australian Bureau of Statistics (2021), 91.4% of residents live in separate low-density houses, with only 0.9% living in flats or apartments. The City of Greater Bendigo recognises a collective hesitation from residents to live in medium to high-density forms of housing, as there is a sense of incongruence associated with accommodation that is viewed as uncharacteristic of heritage and neighbourhood aesthetics, as stated in the Greater Bendigo Residential Strategy (2018. P. 18). However, medium to high-density infill housing is often associated with Transit Oriented Development (Knowles et al. 2020) and has been implemented in many emerging suburbs within Metropolitan Melbourne.

Euclidean Distance: The primary method of analysis utilised Euclidean Distance, which only accounts for proximity alone and foregoes potential barriers to accessibility. For further analysis, it may be helpful to use the Network Analysis to provide a more nuanced interpretation of smaller study areas. According to the official ESRI ArcGIS Pro website, Network Analysis can determine the fastest route from destinations, the service area in minute intervals and even the most profitable location for businesses (ESRI, n.d). Network Analysis may be an invaluable tool to fulfil the ambitions of creating 10 Minute Neighbourhoods for the Greater Bendigo Region, as 10-minute service areas could be identified and developed.

Conclusion With the powerful ArcGIS Pro application, this report has identified potential urban growth areas within the Greater Bendigo region. The selected urban growth areas have adhered to the principles laid out within preexisting strategic plans, including improving connectivity throughout the transit network and existing amenities, promoting a healthy community and restricting future development within the urban growth boundary.
