To prevent unauthorised vehicles entering an area.
Provides a visual and physical barrier that compliments the natural environment.
Sustainable
Plant tree species of an adequate height and maturity to deter vehicles (ensure CPTED sightlines are maintained for safety and security).
Tree guards and tree stakes may be useful as a further deterrent. Consider adding delineators to stakes/tree guards to alert vehicles to the presence of a barrier.
The following alternative options to gates are discussed in further detail in the table below. Some alternative types are NOT preferred, except where specified for a particular application:
Removable bollards (Not preferred. Only install where a high level of finish is required. Approval is required).
Slip rail (NOT to be used unless there is limited space for a swing gate).
Chain gate (must NOT be installed).
See Table 14: Alternative to installing gates.

Alternative to vehicle gates/Application
Application
Key considerations
Removable bollards (NOT preferred)
(includes drop down bollards)
Only install where a high level of finish is required.
Approval is required
Prevents unauthorised vehicles entering an area, whilst providing access for approved vehicles (i.e. maintenance and emergency)
Provides a visual and physical barrier, whilst maintaining an unrestricted path of travel for pedestrians.
Not preferred for vehicle access at most locations. Consider the size, material and method of safe operation. Lifting may require an aid.
‘Removable bollards’ versus ‘hinged vehicle gates’:
Hinged vehicle gates provide a superior solution to workplace health and safety issues (heavy lifting, reduced twisting and turning).
In some instances, a hinged vehicle gate has the potential to interrupt the flow of pedestrian traffic and is therefore not appropriate for the particular site. Where the site requires an uninterrupted path for pedestrians, while providing access for approved vehicles and keeping unauthorised vehicles out, a removable bollard (or drop down bollard) may be appropriate.
Hinged vehicle gates offer a better solution where there are events in open space areas. Community members may require temporary vehicle access to the park (by using an events key)
In some instances, a hinged vehicle gate may not be practical due to the lack of opening arc space.
Some sites may require a higher level finish, where approved by asset custodian.
Where a removable bollard may be considered, please note the following:
Drop down bollards may provide a superior alternative (refer LIM Bollards for further guidance).
Consider the size, material and method of safe operation for a removable bollard.
Where removable bollards (or drop down bollards) are installed in place of a vehicle gate, consider adding delineators to alert vehicles to the presence of a barrier.
Where a removable bollard (or drop down bollard) is to be installed on a pathway, refer LIM Bollards for further guidance.
Slip rail (NOT preferred)
Only install this gate type where there is insufficient space for a ‘swing’ gate
Approval is required
Prevents unauthorised vehicles entering an area, whilst providing access for approved vehicles (i.e. maintenance and emergency)
‘Slip rail’ versus ‘hinged vehicle gates’:
Slip rail gates present workplace health and safety issues (heavy lifting, restrictive twisting and turning movements).
Hinged vehicle gates provide a better solution where there are ‘events’ in open space areas, community members may require temporary vehicle access to the park (by using an events key).
In some instances, a hinged vehicle gate may not be practical due to the lack of opening arc space.
Both a hinged vehicle gate and a slip rail gate, have the potential to interrupt the flow of pedestrian traffic and is therefore not appropriate for the particular site. Where the site requires an uninterrupted path for pedestrians, while providing access for approved vehicles and keeping unauthorised vehicles out, a removable bollard (or drop down bollard) may be appropriate.
Where it is identified that a slip rail gate may be considered, please note the following:
Ensure that the slip rail is able to slide completely through to allow for clear vehicle entry/exit. Ensure there are no barriers adjacent to the gate that would prohibit the rail to slide to its full extent (i.e. obstructions such as boulders, bollards and trees).
Consider installing the adjacent bollards with a top groove so the slide rail can be slid directly across to rest on them, to prevent the end dropping on the ground.
Consider the size, material and method of safe operation of the slip rail gate.
Chain gate (MUST NOT be installed)
Chain between posts/bollards MUST NOT be installed
Low visibility – a chain is not readily visible.
Safety risk – a galvanised or stainless steel chain is generally set at a height where it may pose a risk of falls or trip hazard for pedestrians, particularly people with low vision.
