For this project, there are three major supply types considered for residential land: broadhectare; established urban area; and rural residential.
Broadhectare is defined as new development on greenfield sites (sites that have not been used for urban development previously or previously subdivided for normal density development), typically on the fringe of the established urban area.
Major Infill is defined as undeveloped land or sites identified for redevelopment within the existing urban area, zoned for residential development, and parent lot or existing lot greater than 5,000sqm and with an expected lot/dwelling yield greater than 10.
Minor Infill or vacant lots is defined as vacant land within the existing urban area or within broadhectare land release areas, zoned for residential development, and existing lot sized less than 5,000sqm.
Potential Residential (unzoned) is land identified by the relevant municipal authority for future residential development and current zoning not supportive of ‘normal density’ residential development. Land which has an ‘Urban Growth Zone’ applied, and a precinct structure plan has not yet been approved, falls into this category.
Rural Residential is defined through the zoning, in particular Low Density Rural Residential (LDRZ) and Rural Living (RLZ) zones.
Future Rural Residential is land identified by the relevant municipal authority for future rural residential development and current zoning not supportive such residential development. Future rural residential lands can be for the purpose of either Low Density Rural Residential (LDRZ) or Rural Living (RLZ) development.
Residential lot construction has been determined via the assessment of the residential cadastre and the application of this cadastre to the land supply types identified above.
A constructed lot is defined by the year of construction and the finalisation of certificate of title.
Construction activity has been assessed on an annual basis as at July of each year from 2006 to 2014, additional analysis has been included to identify lot construction to March 2015.
Staging for lot construction or development timing has been established for four broad time periods, namely:
A no timing category has been established for potential residential development sites that are within low demand areas (generally small outlying settlements). These sites typically in addition are allocated a zero potential lot yield. They are identified as potential and are measured by area.
Where land has been identified as ‘Potential Residential’ there are no associated timings, as timing cannot be confidently applied until such time the land is zoned to allow residential development to occur. Similarly, land which is within an Urban Growth Zone, where a precinct structure plan has not been approved, falls into a similar category. At such time a precinct structure plan has been prepared and approved, potential timings of residential development associated to these areas can be applied with a higher degree of confidence.
In this project every parcel of land is deemed to be unavailable or available as supply.
The online reporting tool presents a variety of geographical boundaries (in addition to custom areas) for which the land supply information can be extracted, these include:
The G21 Regional Growth Plan (the Growth Plan) is one of eight plans being developed across the state to manage growth. The Growth Plan has been developed in partnership with the five G21 Geelong Region Alliance councils (Colac Otway, Golden Plains, Surf Coast, Queenscliffe and Greater Geelong), State Government departments, Corangamite CMA and the Committee for Geelong.
The purpose of the Growth Plan is to manage growth and land use pressures to 2050. The Growth Plan provides a regional land use and settlement planning framework which will guide local level planning and infrastructure planning. It pulls together the strategic land use and growth planning already done across the region and sets out where future residential and employment growth will occur and the critical infrastructure required to support it.
The 2015 Update presents completely-revised data for three of the five G21 Geelong Region Alliance councils (Golden Plains, Surf Coast, and Greater Geelong).
The G21 Land Supply Monitor provides a visual representation of the information collected as part of the residential and industrial land supply assessment. There are separate reports detailing the residential and industrial land demand and supply situation for the municipal areas of Geelong, and Surf Coast and the southern component of the Golden Plains Shire that can be accessed through the G21 Regional Growth Plan website (www.g21regionalgrowthplan.com.au).
Details of the methodology used are available in "Residential & Industrial Land Supply - Background Paper" and in the introductions of the demand and supply reports for each council.

The G21 Land Supply Monitor is a web based mapping application and can be accessed from any computer connected to the internet using a web browser such as MicroSoft Internet Explorer, Mozilla FireFox or Google Chrome.
The G21 Land Supply Monitor application enables the user to work with the residential and industrial land supply data, overlayed onto Google Maps.
In order to do this, the G21 Land Supply Monitor application uses the Google Maps API service as its core. This means that basic navigation and interaction with the maps is the same as that experienced by users when using Google Maps elsewhere.
However, the G21 Land Supply Monitor application does much more: it allows the user to load the residential and industrial land supply data, interrogate that data, and generate reports on that data. The application allows the user to load the spatial datasets from G21 Councils which are displayed on top of the Google Maps as extra layers, and then interrogate and report on theselayers. The user can do this via the application's four key tools: the G21 Councils selector, the Layer Control, the Button Toolbar and the Generate Report function.
The G21 Geelong Region Plan contains five membership municipalities: the Borough of Queenscliffe, the City of Greater Geelong, Colac Otway Shire, Surf Coast Shire and the southern section of Golden Plains Shire. For the 2015 Update, data revisions were undertaken by three of the original 5 LGAs - namely, Golden Plains, Surf Coast, and Greater Geelong. The G21 council's selector tool allows users to select data for individual councils. The user can select just one of these councils, or select a combination of councils: if the user selects Golden Plains and Surf Coast, the application will display data for both of these councils.
The G21 Land Supply Monitor application separates spatial information into layers. This means that the user can show or hide information on the map by selecting which layers they would like displayed, and how they would like each of those layers displayed. It also means that the user can have multiple layers of information overlayed onto Google Maps, at the same time.
This interactive Layer Control allows user to do a number of things with the layers:
- User-defined layer - when the user creates user-defined custom shapes, they are stored as objects in the Custom Layer. These shapes can be used to generate reports. (Refer to section 'Custom shapes'.)
- Display layer - users can switch layers on/off, by checking/unchecking the display layer box. A checked box means that the layer is displayed.
- Reorder layers - the user can drag layers up and down in the layer control, to change the order in which layers are displayed in the map window. This is also known as the "stacking" of layers.
- Legend - the user can turn on/off the legend, by checking the Legend box. The legend is dynamic - and only shows the information for the displayed layers.
- Set Queryable - the user can set a layer to be active, so that they can use the toolbar's Info Tool and Copy Boundary tools. Only one layer at a time can be selected for this purpose.
- Set Transparency - for each layer, the user can adjust the transparency of that layer. Making a layer more transparent makes the displayed layers below it more visible.
The Button Toolbar helps the user to interact with the map. To activate any of the functions in this toolbar, first click on the relevant button.eg. to activate the Zoom In function, first click on the Zoom In button.
Draw a rectangle around the area by dragging the Zoom-in tool diagonally across it. The area enclosed by the black rectangle is the area that will be zoomed in upon. Google Maps then enlarges the selected area to fill the Map window. You can repeat this procedure as desired.
Click the Zoom-out cursor on the centre of the area you want to zoom out from. This will increase the visible area of the map by a single zoom level. The map is redrawn placing the point at the centre of the Map window in the zoomed-out view. You can repeat this procedure as desired.
For every data layer in the map, there is also a table of information. The user can access that information by using the Info Tool.
First, the user needs to decide which layer they are interested in - then in the Layer Control select "Set Queryable" for that layer. This sets the layer to active, so that it can be queried. Only one layer at a time can be set to active.
Then, select the toolbar's Info Tool - and click on objects in the active layer. When an object is selected with the Info Tool, a window will display information from the table about that object.
In addition to using pre-defined areas - users can create user-defined areas, edit those areas, and then generate reports on those areas.
The user can create their own area, by using the Draw Circle, Draw Polygon, or the Copy Boundary tool.
For example, a circle might be used to represent a simple catchment... or a polygon might be used to represent a complex region.
Draw Circle, Draw Polygon
The user can draw their own shape using the Draw Circle tool or the Draw Polygon tool.
Once a shape is drawn, it creates an object - that object is stored in the Custom Layer (and can be edited in that layer).
Alternatively, the user can copy an existing shape, from a selectable layer in the Layer Control.
To copy a shape - first, the user needs to determine which layer the desired object sits in and make that layer active (go to Layer Control, Set Queryable). Then, on the toolbar the user selects the Copy Boundary tool, and then clicks on the desired object. This immediately copies the shape, and pastes it into the Custom Layer (without the user needing to do anything else). The user can then edit this new object in the Custom Layer.
When a shape is drawn or copied, it creates an object - that object is stored in the Custom Layer.This object can be renamed or reshaped. Circles can also be moved. All shapes can be deleted entirely.
To name (or rename) an object in the Custom Layer - the user simply right clicks on the object.Naming objects in the Custom Layer is helpful for creating reports.
Reshape, move, delete
To reshape, move or delete an object:
1. In the Custom Layer, the user selects the object (Left click on object)
2. On the toolbar, the user selects the Reshape Boundary tool
3. The user can then edit the object. This varies slightly, depending on if the shape is a circle or a polygon.
For each circle object in the Custom Layer - the user can change the radius of that circle, or move the entire circle. When a circle is selected, and the Reshape Boundary tool is active - 5 nodes are visible on the circle.
Change the radius of the circle- the user drags one of the 4 outer quadrant nodes
Move the entire circle - the user drags the centre node
Delete entire shape(s)- the user presses the delete key
For each polygon object in the Custom Layer - the user can move, add or delete nodes that define line segments. When a polygon is selected, and the Reshape Boundary tool is active - the nodes are visible on the polygon.
Delete a node- the user right clicks on node
Move a node- the user drags the node
Delete entire shape(s)- the user presses the delete key
The G21 Land Supply Monitor application has an inbuilt versatile reporting functionality, which allows the user to define an area of interest and then produce a range of different reports on that area. Reports can also be saved.
To generate a statistical report, you need to specify 3 key pieces of information: "What?", "How?" and "Where?"
The user selects the type of report they would like generated.
There are 4 reports that are available for all G21 Council areas, namely Residential Supply, Rural Residential, Vacant Urban Lots and Industrial Supply).
The user selects how they would like the results to be summarised (within the report)
The user selects the area of interest. ie. the area for which they wish to generate a report.
Using the drop down list, the user can use select:
- one of the application's standard geographies, There are 6 standard options from which to chose: Local Government Area (LGA), Statistical Area Level II (SA2), id Projection Boundaries, Structure Plan Boundaries, Industrial Precinct and Urban Centre. The user can select 1 geography per report.
- their own user-defined geography. There is only one option: Custom Layer. (Refer to section 'Custom shapes'.)
Once the user has selected an item in the drop down list, another list will appear in the box below.
The user can then select one or more of these items, and add them to the Reported Area list and the user can then generate a report.
