8.2.18 Road hierarchy overlay code

8.2.18.1 Application

(1) This code applies to assessing development on of land adjoining or having frontage or access to roads identified in the Road hierarchy overlay, if:
(a) self-assessable or assessable development where this code is an applicable code identified in the assessment criteria column of a table of assessment for an overlay (section 5.10); or
(b) impact assessable development.
(2) The Road hierarchy overlay map identifies the following sub-categories:
(a) Motorway sub-category;
(b) Arterial road sub-category;
(c) Suburban road sub-category;
(d) District road sub-category;
(e) Neighbourhood road sub-category;
(f) Local road sub-category;
(g) Future motorway sub-category;
(h) Future arterial road sub-category;
(i) Future suburban road sub-category;
(j) Future district road sub-category;
(k) Primary freight route sub-category;
(l) Primary freight access sub-category.
(3) When using this code, reference should be made to section 1.5 and section 5.3.3.

Note—Where this code includes performance outcomes or acceptable outcomes that relate to road types, traffic impact reports and hierarchy design and construction, guidance is provided in the Infrastructure design planning scheme policy.

Editor's note—Standards for the provision of trunk infrastructure are specified in the Priority infrastructure plan.

8.2.18.2 Purpose

(1) The purpose of the Road hierarchy overlay code is to:
(a) Implement the policy direction in the Strategic framework, in particular:
(i) Theme 4: Brisbane’s highly effective transport and infrastructure networks and Element 4.1 – Brisbane’s transport infrastructure networks;
(ii) Theme 2: Brisbane’s outstanding lifestyle and Element 2.1 – Brisbane’s identity.
(b) Provide for the assessment of the suitability of development in the Road hierarchy overlay.
(2) The purpose of the code will be achieved through the following overall outcomes:
(a) Development contributes to the safe and efficient operation of the existing and planned road hierarchy and to the function of the road as part of Brisbane’s public domain.
(b) Development accessing roads is consistent with and does not compromise the road hierarchy in its use, function, flow, or capacity by buses, pedestrians and cyclists.
(c) Development that changes the function of a road by generating traffic does so such that the new function of the road in the hierarchy is compatible with the surrounding road hierarchy and where necessary is reconstructed to meet its new design parameters.
(d) Development that provides a new road internal and connecting to the road hierarchy complements or completes the existing road hierarchy.
(e) Development does not compromise the completion of the road hierarchy.
(f) Development ensures that land uses are located to support and implement a safe and efficient road hierarchy facilitating the efficient movement of people and goods.

8.2.18.3 Assessment criteria

The following table identifies the assessment criteria for self-assessable and assessable development.

Table 8.2.18.3—Criteria for self-assessable and assessable development
Performance outcomes
Acceptable outcomes
Section A—If for self-assessable or assessable development for a material change of use
PO1
Development ensures that:
(a) vehicle access is provided to each premises, which has no significant impact on the safety, efficiency, function, convenience of use or capacity of:
(i) the road hierarchy shown on the Road hierarchy overlay map;
(ii) public transport operations;
(iii) pedestrian and cyclist movement;
(b) site access driveways in the road area accommodate all turns only when such arrangements are safe and can be demonstrated to not inhibit transport system operation.
AO1.1
Development ensures that an access driveway is provided from:
(a) a minor road;
(b) a district road or suburban road if the development has high traffic-generating potential.
AO1.2
Development ensures that an access driveway is not provided to or from a primary freight route identified on the Road hierarchy overlay map.
AO1.3
Development ensures that a use other than a use with high traffic-generating potential gains all vehicular access, other than for service vehicles, via the lowest order road in the road hierarchy to which the site has frontage.
AO1.4
Development ensures that a turn to and from a major road is restricted to a left turn only.
AO1.5
Development ensures that vehicle access is provided to an abutting site that only has frontage to an arterial road, to facilitate access to the abutting site via an alternative street.
Section B—If for assessable development for a material change of use
PO2
Development does not compromise the safety, efficiency, function, convenience of use or capacity of the operation of the existing and future road hierarchy, and addresses all the impacts on the road hierarchy.
AO2.1
Development ensures that the traffic generated by the development is consistent with the adjoining road’s hierarchical classification, function and expected traffic flows.
AO2.2
Development mitigates an impact on the road hierarchy if the development:
(a) is for a major development; or
(b) involves an access driveway to a major road; or
(c) involves an access driveway within 100m of a signalised intersection.

Note—This can be demonstrated in a transport impact assessment report prepared and certified by a Registered Professional Engineer Queensland in accordance with the Transport, access, parking and servicing planning scheme policy.

Section C—If for assessable development for a material change of use or reconfiguring of a lot
PO3
Development makes provision for future extension, expansion and widening of the existing and future road hierarchy where required.
AO3
No acceptable outcome is prescribed.
If on a site in or adjacent to a planned infrastructure corridor on an Infrastructure corridor plan
PO4
Development protects a planned infrastructure corridor on an Infrastructure corridor plan, being:
(a) planned trunk infrastructure beyond the planning horizon for which a level of strategic and concept design planning has been carried out by the Council;
(b) an item of development infrastructure of importance for future development in the planning scheme area;
(c) for the maintenance of proper standards in local development.
AO4
Development protects a planned infrastructure corridor identified on an Infrastructure corridor plan in accordance with the Infrastructure design planning scheme policy.
Section D—If reconfiguring a lot or involving an extension or change to the road hierarchy
PO5
Development ensures that a new road connection into the road hierarchy provides:
(a) safe, efficient and convenient external connectivity of the new movement system to the major road network;
(b) a minimum number of intersections to the major road network.
AO5
Development provides access to an appropriate road within the road hierarchy for the area and the extended road system meets the objectives of the wider road hierarchy and neighbourhood accessibility.
PO6
Development ensures that an extension of or change to the road hierarchy:
(a) provides internal connectivity of the movement system to the neighbourhood;
(b) provides pedestrian connectivity to facilitate ease of access by the shortest reasonable route to neighbourhood facilities, parks, schools, shops, bus routes, transport facilities or open space systems;
(c) provides cycle connectivity to facilitate ease of access by the shortest reasonable distance to the next higher order cycle route;
(d) includes the provision of bus routes in the road hierarchy that provide ease of access to bus customers;
(e) minimises vehicle volumes and speed in residential streets while providing connectivity to higher order roads in a reasonable travel time;
(f) provides a street layout that minimises travel time and traffic volumes on neighbourhood roads;
(g) provides low permeability of street layout to positively discourage through traffic while achieving high permeability for pedestrian and cycle networks;
(h) provides safe accessibility to lots by having more than one street providing access to the area;
(i) addresses all the impacts on the road hierarchy.
AO6.1
Development ensures that a new or upgraded road is designed and constructed in accordance with its classification in the road hierarchy and the standards in the Infrastructure design planning scheme policy.
AO6.2
Development mitigates any impact on the road network.

Note—This can be demonstrated in a transport impact assessment report prepared and certified by a Registered Professional Engineer Queensland in accordance with the Transport, access, parking and servicing planning scheme policy and the Infrastructure design planning scheme policy (Traffic impact assessment and definitions section).

PO7
Development ensures that premises and vehicle access is located and controlled so as to have no significant impact on the safety, efficiency, function, convenience of use or capacity of the major road network and its hierarchy.
AO7
Development ensures that residential lots are laid out to ensure a future use does not directly ingress from or egress to a major road.
PO8
Development ensures that an intersection is designed and constructed in accordance with its hierarchical classification as shown on the Road hierarchy overlay.
AO8
Development ensures that an intersection is designed to the standard of the highest order road at the point of intersection in accordance with the road design standard in the Infrastructure design planning scheme policy.
