Infrastructure Development Code


The following shall also be considered as part of the design process:

  1. DS-5.9.1 Trenchless Technology.
  2. DS-5.9.2 Access Requirement.
  3. DS-5.9.3 Fencing.
  4. DS-5.9.4 Easements.
  5. DS-5.9.5 Rural and Rural-Residential Zones.

DS-5.9.1   Trenchless Technology

Trenchless technology may be preferred or required for alignments passing through or under:

  1.  Environmentally sensitive areas.
  2. Built-up or congested areas to minimise disruption and reinstatement.
  3. Railway and major road crossings.
  4. Significant vegetation.
  5. Vehicular crossings.

Refer to CS-5.8 Trenchless Technology for information on trenchless technology installation. 

DS-5.9.2   Access Requirement

Where any assets are being created as part of a stormwater management system that is to be maintained by Council, legal and practical access shall be provided for maintenance. For the purpose of this standard provision legal and practical access shall be a minimum of a 4.0m wide access path constructed to an all weather standard able to accommodate an 8.2 tonne design axle load.

DS-5.9.3   Fencing

Drawing Ref: T320, T321

The following shall apply:

  1. The fencing of open watercourses and ponds is not required unless the watercourse has vertical or near vertical sides. In this case the provisions of the Building Act apply. 
  2.  Fencing may be a condition of easements for constructed waterways or drainage structures. A permeable fence (i.e. that can be seen through, rather than a solid construction), is recommended. 
  3. Fences shall not significantly impede flood flows. 
  4. Fencing shall not be permitted across overland flowpaths unless approved by Council.

DS-5.9.4   Easements

Please refer to:

  1. DS-1.22 Easements
  2. DS-1.22.8 Easements: Stormwater and Wastewater

DS-5.9.5   Rural and Rural-Residential Zones

Rural-residential zone stormwater systems shall be designed in accordance with the IDC. Flexibility may be considered where the risk factors are less significant for rural zone stormwater system design. These designs shall be subject to Council approval.
