Shire Council is preparing the Bannockburn Growth Plan (the Growth Plan) to guide the sustainable development of Bannockburn to the year 2050. 1.2.1 Planning for Growth Bannockburn has a population of around 7,000 and is the largest town in The Growth Plan is a long-term land use plan for the current and future Golden Plains Shire. urban areas of Bannockburn. It is a broad high-level strategy that: The town has consistently been one of the fastest growing regional areas in • Sets out a vision for Bannockburn. Victoria, mainly due to its affordable housing, infrastructure and proximity • Guides sustainable growth and development over the next 30 years. to Geelong. • Identifies the steps needed to manage growth. The Growth Plan responds to the Minister for Planning’s support to review • Defines key projects and infrastructure required to support growth. existing planning mechanisms to accommodate additional population growth and new employment opportunities in Bannockburn. It will provide • Provides a decision making framework for public and private a strategic basis for infrastructure and service planning as well as the investment. sequencing and staging of land release. The Growth Plan addresses key challenges to guide housing, employment, infrastructure, services and other opportunities for residents and visitors This paper has been prepared to identify a possible future road network while ensuring Bannockburn becomes more accessible, sustainable and and arterial road options for investigation for Bannockburn. It provides an liveable. The Growth Plan aims to maintain and enhance the unique assessment of existing network conditions and investigates the need to attributes of Bannockburn and sets a vision for how the urban area will expand the arterial road network to accommodate projected growth. grow and change until the year 2050. Bannockburn Growth Plan - Traffic network assessment – August 2020 5 1.2.2 Planning Context Set within the listed hierarchy, in regional Victoria, Growth Area Framework Plans set the framework for urban growth based on the strategic Growth Area Framework Plans sit within the planning hierarchy that directions of Regional Growth Plans. The relevant Regional Growth Plan for comprises a framework of State, regional and local policies. Bannockburn is the G21 Regional Growth Plan. They identify future precincts where more detailed planning work will take place in the future in the form of precinct structure plans or development plans. In terms of their content, Growth Area Framework Plans show: The State and Local Planning • broad land use patterns Policy Framework (including Melbourne 2030) • committed and proposed transport networks and regional open space • significant aterwaysw and areas of potential environmental sensitivity Growth Area Framework Plans Precinct Structure Plans Planning Permit Applications (ie. subdivision) 6 Bannockburn Growth Plan - Traffic network assessment – August 2020 1.2.3 Components of the Plan 1.3 TRANSPORT NETWORKS AND OPTIONS The components of a Growth Area Framework Plan are described within FOR INVESTIGATION the Victoria Planning Provisions (VPPs).

The investigation area extends to the south and west of the existing urban area of Bannockburn. The southern boundary of the investigation area is the Gheringhap to Maroona freight railway line. The western boundary is the Bannockburn recreation reserve. Refer Figure 1.

Bannockburn-Shelford Road serves as the only district crossing of both Bruce’s Creek and the Geelong to Figure 3 Midland Highway upgrade options Ballarat freight railway line, highlighting the lack of network resilience within Bannockburn (see Figure 2). The bridge over Bruce’s Creek is at the western edge of the town and the railway level crossing is on the bend between High Street and Geelong Road at the north-western edge of the central commercial area. Bannockburn-Shelford Road is a Declared Arterial Class C road and approved B-double route. It has a single traffic lane in each direction along most of its route plus local access service roads through the central town area. Bannockburn-Shelford Road and Geelong Road have a posted speed limit of 60km/hr through the central township, beyond which they transition to 80km/hr. The Midland Highway bounds Bannockburn to the north, connecting Geelong through to Ballarat via Meredith. The intersection of Midland Highway and Geelong Road is controlled by a roundabout which marks the start of the Bannockburn townsip.
