Introduction
Replaces (ITS Section 1, Clause 1.1.2)
This volume has been prepared as a supplement to the Hamilton City Infrastructure Technical
Specifications (ITS) for use by the Waikato District Council.
This section sets out general variances to the Infrastructure Technical Specifications and/or additional
design standards or technical specifications that should be followed for the installation of services in
subdivision and contract works in the District Council area.
Where there is any discrepancy between this section and the council’s District Plan, then the District
Plan shall have precedence.
Any ambiguities between documents should be addressed in the first instance by referring to the
hierarchy below, and then by contacting the District Council directly if uncertainty remains.

Area Supplement (this document)
Hamilton Infrastructure Technical
Specifications
Where possible, reference to the original Hamilton ITS clause that has been amended or added to is
given in the appropriate location in bracketed italics. Where there is no reference this is either a new
requirement not alluded to in the Hamilton ITS, or the requirements are spread over several nonsequential sections or clauses which makes it difficult to reference.

“Intersections at Grade” - Austroads Guide to Traffic Engineering Practice – Part 5 (AP-G11.5/05)
9.4.3
Road Names
The Council, wherever possible, will seek to use road names as a way of recognising significant history of
an area. Some Community Boards and Committees have developed a list of “Approved Road Names”
for naming new roads in their community. Where these exist, the developer shall choose from that list
or submit a written request to use other names, including the reasons why they want that name or
names to be used.
Refer to Council’s Road Naming Policy on Council’s website for further details.
Council will arrange any necessary authority for the regulatory signage and marking. All costs associated
with the gazetting and implementation of the traffic services are to be paid by the consent holder.
9.4.4 Road Classification
HCC’s Criteria for the form of Transport Corridors (ITS Section 3, Appendix A) has been replaced for the
District Council by Appendix A of this document.
9.4.5 Geometric Standards
Typical cross section requirements relating to Waikato District Council are shown on the Road
Classification Table in Appendix A, or the District Plan.
Turning heads will be required at the end of all no-exit roads in accordance with Austroads Rural Road
Design.
9.4.6 Geometric Design
Geometric design, including gradients, super elevation and road widening shall generally be in
accordance with the Austroads publication “Guide to Geometric Design for Rural Roads” except for the
following points:
9.4.6.1
Crossfall
(ITS Section 3 Clause 3.2.2.3)
Normal crossfall in rural areas may be -3.0% or -4.0% at the designers discretion.
Page 4
Last Updated: 31 October 2014
Section 9 Waikato District Council Supplement
9.4.6.2 Super-elevation
(ITS Section 3 Clause 3.2.2.4)
Super-elevation shall not normally be required on curves in rural/residential subdivisions.
Where it is required, super elevation design shall generally be carried out using Austroads Guide to Rural
Road Design. See Road Classification Table in Appendix A for maximum super-elevation at intersections.
9.4.6.3
Longitudinal Gradients
(ITS Section 3 Clause 3.2.2.5)
Where Kerb and Channel is not required or proposed, there is no minimum longitudinal gradient on the
road.
9.4.6.4 Turning Heads
(ITS Section 3 Clause 3.2.11.2)
The maximum longitudinal, or cross sectional slope in turning heads is 6.0%, with the desirable matching
normal camber.
9.4.7
Walkways
(ITS Section 3, Clause 3.2.16)
Rural residential subdivisions should make provision for pedestrian access along grass berms. Refer to
the District Plan, or Appendix A of this document.
9.4.8 Road Reserves and Fencing
(ITS Section 3, Clause 3.2.1 to 3.2.8)
Adequate width of road reserve is important and is normally 20 metres. Increased width is likely to be
required where earthworks are extensive. A minimum clearance of 3 m is required between the road
reserve boundary and tops of cuttings or toes of embankments.
All road reserve boundaries shall be fenced before the 224 certificate will be authorised, unless written
permission to do otherwise has been received from the District Council.
9.4.9 Pavement Design
9.4.9.1
Subgrade Improvement Layer (Blue/Brown Rock)
Further to (ITS Section 3, Clause 3.3.2.3), the following requirements shall also apply for the application
of blue/brown rock:
In some places, the blue/brown rock material needs to be tapered to thicknesses less than the materials
maximum size. Therefore an AP40 material may be used in the finishing of this sub-base layer to ensure
that this can be achieved.
The construction shall comply with NZTA B/2, however the Contractor shall carry out the compaction
testing (may need to break up larger particles to perform the compaction curve and CBR test to replicate
field conditions). The Contractor shall confirm that the target density will consistently satisfy the
minimum CBR requirement

2. Basecourse aggregates for unbound pavement shall be NZTA M/4 only
9.4.9.3
Unsealed Pavements
Unsealed pavements shall be compacted with a minimum compacted thickness of 300mm of well
graded granular material with a minimum soaked CBR of 20. The maximum particle size shall be no
greater than 100mm. This pavement material shall have sufficient fines to ensure that it does not
unravel under the action of traffic. A material typically used on Waikato District Council unsealed roads
is a high grade brown rock but will vary depending on locality. A 50mm minimum compacted thickness
wearing course shall then be constructed using WHAP20. Normal camber of unsealed pavements shall
be 5 to 6%.
9.4.10 Drainage and Culverts (Road Drainage)
(ITS Section 3, Clause 3.2.14)
Channels shall generally be provided for the efficient drainage of surface water (refer to the relevant
table in the appendices or relevant District Plan) and shall be graded to outlets at regular intervals not
exceeding 150m. On steep grades where channels are subject to scouring, protection work may be
required.
Swale drains may be allowed in suitable locations at the District Council’s discretion.
Culverts, where required, shall be designed in accordance with approved engineering standards.
Notwithstanding the outcome of any design calculations, no culvert traversing a road or vehicle
entrance shall be smaller than 300mm in diameter.
In non-urban subdivisions where stormwater from the road formation and adjoining properties cannot
be discharged via either open channels or a piped system to an approved outlet, the construction of
drilled and lined soak holes and/or roadside berm drainage beds are options. Any application for this
type of disposal system must be accompanied by results of soil percolation tests, specifications and
design calculations for Council’s approval. The design and testing of these drainage systems shall be
carried out by an approved geotechnical engineer.

9.9.1
Location of Above Ground Services
Utility location drawings shall be submitted to the General Manager Roading and Projects for approval
prior to any works commencing. Where the adjacent carriageway design speed is 80kmh or greater, all
new services to be placed above ground shall be outside the Clear Zone defined in the WDC Table 3.1,
unless specifically authorised in writing by the Roading Group Manager. This shall include service poles
(unless frangible or where AADT >1000 slip-base type installations shall be specified) and stays, as well as
service cabinets and pedestals.
9.9.2 Waterway Crossings
Any services crossing drains or waterways within the road reserve shall do so without utilising Council
road bridges or culvert crossings unless specifically authorised by the Roading Group Manager. Any such
approval will be given at Councils pleasure and the services shall be relocated, at the service owners cost,
at Councils request at any time.
9.9.3
Location of Underground Services (As-built Drawings)
An electronic record shall be provided suitable for direct input to the Council GIS system, (ie: Mapinfo
Tables in NZTM) showing the location of all buried services within the road reserve. Depth and detailed
(commercially-sensitive or otherwise) specifics of the services are not required (unless the stipulated
minimum cover has not been achieved). This information is necessary for the management of the road
reserve asset, including forward planning of future roading and services development.
9.9.4 Broadband
The developer shall make arrangements with a broadband network provider to provide for the supply
and installation of broadband services. This shall involve the design and installation of appropriate
ducting, in readiness for the installation of broadband cabling.
Where a broadband network provider is not able to provide a suitable layout then the developer shall
use a nominated Broadband designer to provide a suitable detailed design at his expense.
Installation of broadband services must comply with the National Code of Practice for Utilities Access to
Road and Rail Corridors, and National Environmental Standards for Telecommunications Facilities:
1. The reticulation shall be provided underground to a minimum final cover depth of 600mm
below finished surface level. A suitable copper location wire shall be installed with the duct.
2. The reticulation shall be installed in the road berm, parallel to property boundaries, where
possible. All properties shall be serviced.
3. The reticulation shall not compromise or obstruct other infrastructure in the road corridor
and should also take into account the potential impact on other utility infrastructure. The
reticulation shall not be located within 400mm of any Council service. If this cannot be
achieved, Council may require the developer to undertake post construction CCTV inspection
of Councils services, at the cost of the developer to ensure that no damage has occurred to
these Council services during installation and construction. The developer shall consider
future access points to avoid conflict with other infrastructure.
4. The ducting shall have a minimum internal dimension of 100mm diameter.
5. The ducting shall be uPVC plain wall pipe with a minimum SN 4 rating.

6. The ducting shall provide for the installation of fibre optic cabling and shall adhere to
minimum bending radii requirements for the cable on all changes of direction
7. The ducting shall be purple in colour.
8. The layout of the ducting should be such as to minimise disruption and disturbance when
cabling is installed.
9. The design of the ducting shall reduce and minimise the requirement for ongoing
maintenance and ensure the maximised lifespan of the infrastructure.
10. Should an above ground cabinet or chamber be required, this shall comply with the relevant
provisions of the District Plan. At least 20 working days notice shall be given to Council of the
developers or Telecommunication operators intention to install a cabinet or chamber on
Council owned or controlled land.

reversing. The design dimension should be sufficient to enable a 90 percentile truck to enter and leave the no exit road in a forward
direction after a three-point turn.
(e) Construction of a road or access servicing 5 or more allotments, or 2 or more activities, must have sufficient road reserve width to:
• accommodate any retaining structure or slope necessary to support the road or adjacent property, and
• achieve a complying horizontal alignment and
• accommodate any turning area required by these standards and
• service the potential number of residential units, calculated by zone rules for residential density and possible controlled activity
subdivision, and
• service the traffic generation from non-residential activities likely to use the access, and
• include passing bays on a single lane access, where necessary, having regard to topography of land, sight distances and usage, and
• include an area at the end of a cul-de-sac or no-exit road to allow a 90 percentile two axle truck (HGV) as defined in Figure 3 to
undertake a three-point turn.
