Driveway Approvals Factsheet
Applications can be submitted via the online application form.
Do I need to seek approval from TAMS if I want to replace my
existing driveway?
If you are replacing the driveway with plain or asphaltic concrete without modifying the
original shape, size, location or surface type of the driveway then you do not need approval
for the design of the driveway. Approval is required if and when you change the location,
size or layout of the driveway
If you are only replacing an existing driveway then you are required to book for a site
inspection through the online application form to lodge for the final formwork/sub-base
assessment of the driveway across the verge prior to pouring the concrete/asphalt and
applying the surface finish.
Where do I find the application form?
The application form is located on the TAMS website.
How long will it take to process my application?
TAMS has a maximum assessment time of 15 working days.
What part of my driveway is owned by the Territory?
The driveway from the road to the property boundary is on Territory land and is owned by
the Territory.
Will the Territory construct a driveway on behalf of the property
owner?
Design and construction of all new or modified driveways, including relocated driveways, is
the responsibility of the lessee. All costs associated with the design and construction work
will be the responsibility of the lessee.
Do I require inspection of my driveway?
Yes you do. You are required to contact TAMS Asset Acceptance and organise an
inspection prior to pouring the concrete or placing the top surface layer (asphalt/pavers) for
the driveway. TAMS require a minimum of 48 hours notice for booking an inspection. To
make a booking please phone 6205-8084 or 6207-7386.
What are the standards or requirements for building a driveway?
TAMS Design Standard DS-05 outlines any requirements for design and construction of
driveways including size, grade, clearances and materials.
Can I construct a second driveway?
There is one driveway and kerb crossing for each block. Provided all other provisions below
are met, a second driveway and kerb crossing over the verge may be permitted.


Forward entry to roads carrying greater than 3,000 vehicles per day, or
Large blocks where the visual impact to the streetscape is not adversely affected,
provided the site access is of appropriate proportions and character with respect to:
o Relationship to verge footpath: splay, grade etc
o Total proportion of the width of the access relative to the building width: 5
metres at kerb and 3.5 metres at property boundary etc
o Design features: steepness/grade.
o Protection of existing landscape features: trees and their clearances.
You may construct a second driveway, subject to TAMS conditions for a second driveway
which are located in the Territory Plan and TAMS Design Standard for 5 Driveways DS-05.
What materials are acceptable for driveway construction?
Plain coloured or stamped concrete, bitumen or pavers are acceptable driveway materials.
Exposed aggregate will be allowed under special circumstances on request. Polished
concrete and tiled finishes are not permitted.
What is a vehicle crossing?
The vehicle crossing is the section of kerb that has been removed and replaced in concrete
to allow easy vehicle access from the road. Refer to Figure 1.
Figure 1 Vehicle crossing in kerb, between the road surface and the first expansion joint.
What is the maximum gradient for a driveway?
Maximum upward gradient for a driveway on the verge is 17%. Maximum down grade is
12%. Variations to the design of the driveway in different situations are covered in Design
Standard DS-5. These maximum grades are required for the safe operation of the driveway.
Refer to Figure 2.
Figure 2 Driveway grade.

property boundary and kerb?

Note 1: Single dwelling driveways that do not meet the standard driveway widths may be
supported subject to justification such as matching existing streetscape or in locations where
the front boundary is less than 12 metres in width.
Note 2: The maximum width at the property boundary and kerb line will only be supported
where the driveway is serving a double or larger garage, or multiple dwelling; in all other
cases the maximum is to be as per the standard driveway type R.
I have a double garage; can I widen my vehicular crossing to suit?
Standard driveway width at the kerb can only be increased to a maximum 5.5 metres to
accommodate construction of a double garage providing all clearance requirements are met.
What strength concrete is used for a standard residential
driveway?
Concrete strength is 32 mpa for a standard residential driveway.
When is a standard or industrial strength driveway required?
Standard driveways are for residential dwellings up to three units. Residential dwellings of
four or more units and commercial or industrial dwellings require an industrial strength
driveway.
How do I get approval for an industrial driveway?
Industrial driveway approval is by way of a Design Acceptance submission.
In normal circumstances an industrial driveway should have a Development Application
lodged with ACTPLA. TAMS requests a Design Acceptance obtained from the Senior
Manager, Asset Acceptance for any off site works including driveways in accordance with
the approved Notice of Decision of the Development Application.
I have a footpath running through my driveway. Can I remove the
footpath to construct a new driveway?
We encourage you not to remove the footpath when building a new driveway. However you
are allowed to remove the footpath and reconstruct it as long as the new footpath section is
constructed to TAMS standards DS-05.
Refer to Figures 3 and 4.
Figure 3 This driveway shows incorrect footpath priority. Footpath must have priority over the
driveway.
Figure 4 Driveway with correct footpath priority.
I have an approved Development Application (DA) for either single
or dual occupancy. Do I need to lodge an application to TAMS for
the design approval of my driveway?
Your design would have been approved as part of your DA application. However you still
need to lodge an application for a formwork inspection through the online application form.
There is a tree close to my proposed driveway. Can I still construct
the driveway in that position?
The driveway must be located at least three metres from the outside of the trunk of any
existing new or small tree, and outside of the drip line of mature street trees. However the
ACT Government may approve variations to this requirement upon application.

Definitions
Below is a list of definitions used in this document and by ACT driveway inspectors
and builders.
Driveway
The paved area between the road kerb and the property boundary
where a vehicle can access a property.
Road reserve
The section of land that includes the carriageway and nature strips on
both sides of the carriageway, usually measured from property
boundary to property boundary.
Vehicle crossing
The section of the kerb that has been removed and replaced in
concrete to allow easy vehicle access.
32 MPA
Concrete strength, in mega-pascals, after 28 days in accordance with
Australian Standard AS1379.
Cross fall
The slope at right angles to the alignment given to the surface of any
part of the carriageway – usually expressed as percentage
Grade (gradient)
The rate of longitudinal rise or fall of a driveway – usually expressed
as a percentage.
Formwork
Wooden (sometimes steel) boards used as a mould to contain fresh
concrete in the correct position. The formwork is removed once the
concrete has cured (hardened).
Road base
A graded rock material used to create a base for roads and
driveways.
Nature strip
The area of the road reserve between the kerb and the property
boundary.
