care and maintenance.
PART I - FUNCTIONAL LAYOUT PLAN
A.
PRINCIPLES
Council will require the development of a Functional Layout Plan as a Condition 1
of planning permits associated with staged subdivision development and therefore
it will require endorsement by Council’s Town Planning Department.
A Functional Layout Plan is to be developed subsequent issue of the planning
permit as a process to assist in the planning of road and subsequent to drainage
infrastructure,
physical
layout,
topographic
and
traffic
management
considerations so as to assist in the subsequent completion of detailed
Engineering design.
It is Council’s intention that subdivision functional / layout issues will generally be
resolved during the development of the Functional Layout Plan but accepts that
once the plan is endorsed minor adjustment may be necessary should issues arise
during detailed engineering design.
Note:
B.
1.
In preparing a Functional Layout Plan, consideration must be given
to Brimbank’s subdivisional design guidelines and standards in
PART II – ENGINEERING DESIGN of this document.
2.
Council requires four (4) A1 copies of any documentation (including
the Functional Layout Plan and supporting documents) to be
submitted to the Planning Department.
3.
Before approval of the Functional Layout Plan a road safety audit
may be required.
4.
A road safety audit will be required for any bridgeworks and any
road safety barrier installation.
5.
To assist Council officers in the checking of the plans, the functional
layout plans must be provided, to scale, as hardcopy A1 plans.
Digital versions of the plans may be provided, however, the
hardcopy plans will be the basis of the checking.
6.
Amendments in resubmitted drawing, as a result of Council’s
comments or consultant’s own amendment shall be marked by
'Cloud’ for the case of identification and completion. The ‘Cloud’
shall be removed in the final submission to Council for approval.
7.
If incorrect information is supplied (e.g. existing features) Council
reserves the right to require changes to the functional layout and or
detailed engineering plans at anytime.
WHAT IS TO BE SHOWN ON THE FUNCTIONAL LAYOUT PLAN
The Functional Layout Plan must show:
1.
Topography, including contours of the land and adjacent land and
scaled 1:1000. Contour intervals to be sufficiently clear to show

The finished surface levels at the back of residential allotments are
to be designed in accordance with Rescode section 56.09 so as to
ensure that overflow is directed to the major drainage system i.e.
the road reserve. The back of the lots (from the road reserve) are
not to contain a valley shaped arrangement.
6.
a) The construction plan N.S. levels are to agree with the sealed
plan natural surface levels, if available.
b) Easements on construction plans are to agree with sealed plan of
subdivision.
7.

set-outs must relate to MGA (Map Grid of Australia). Layout must
provide adequate horizontal and vertical control.
8.
Offsets to drainage in easements to be shown to center of drain.
9.
Show alignments and offsets of all services (particularly sewers in
easements) on layout plan - note: engineering plans will not be
approved until service authorities and Council approve of alignment
and clearances. Service offsets and locations shall be in accordance
with typical cross-sections specified by the Street Works Coordination Committee Code of Practice or as agreed with the service
authorities and Council.
10.
Drainage layout

fencing is to be specified on the engineering drawings.
33.
Clear zones requirements are to be met for the protection of
vehicles. Obstacles, batters, culverts are to be located outside the
required clear zone. An appropriate clear zone for any runoff of
vehicles is to be accommodated abutting the road, in accordance to
VicRoads guidelines.
34.
SEC sub-stations, if provided, require a detailed plan showing
relevant above and underground drainage, surface levels and typical
cross sections.
35.
Council requires that barrier kerb and channel is used for all kerbs.
Semi-mountable kerbs are only to be used for such areas as
medians, central islands, roundabouts and other traffic management
devices. Mountable kerbs are to be used at traffic islands where
signage is not used.

area between vehicle swept paths. Appropriate offsets on the
approaches to the traffic island are to be provided in the design.
b. Minimum width of traffic island shall be 600 mm at the narrowest
end and the width is to vary uniformly to take up unused
pavement in the swept paths design.
c. Around a corner bend, a break within the traffic (splitter) island
treatment may be necessary to allow access to the corner
allotments for a car to be driven into the allotment vehicle
crossings and be reversed out and driven away.
d. Kerb types for traffic islands:
SM type profile is to be provided where:
 The tracking path of the largest designed vehicle (within
design parameters of the treatment) traversing the bend is
clear of the traffic island.
 The provision of traffic signs are within the traffic islands and
clear of vehicle overhangs.

M type profile kerb is to be used where:
 The traffic island width is less than 1.2m.
 No traffic signs are to be located in this M type island.
 Tracking paths may require some vehicles to mount the
traffic island.
39.
At residential developments, mounting strips and concrete annulus
shall be included at traffic management treatments to accommodate

burnt orange or red colour.
40.
At industrial developments, only the central annulus at roundabouts
is required and the outer mounting strip may not be required
depending on size of roundabout and tracking paths of largest
design vehicles which are to negotiate the roundabout.
41.
The design and approval of traffic management treatments (TMT’s)
affecting bus services routes (public and school) will also be subject
to the following:

Where TMT’s are located along an existing or proposed bus
service route, consult and obtain written approval from the
Department of Infrastructure, Victoria (DOI) and the operating
bus company.

Where TMT’s are located at future bus routes and on a school bus
route, only DOI is to be consulted for approval.

Where TMT’s are located on a school bus route, consult DOI for
its advice and feedback (and approval if necessary).
