Information for contractors
Experienced contractor
The work shall be carried out by a competent contractor, experienced in the type of work being undertaken. The contractor shall meet all their obligations under the current version of the Health and Safety in Employment Act. All underground services shall be located before any excavation commences. Any work on the road will require an approved Temporary Traffic Management Plan.
Formation
The access requires a minimum sub-base depth of 150mm. The surface shall be compacted metal with a minimum depth of 50mm and maximum particle size of 20mm. No area of the completed surface shall have any depression that will allow water to pond.
Gates
Gates shall be recessed back from road with sufficient distance to allow any vehicle using the access to stop clear of the traffic lanes while the gate is being opened or closed.

Mailboxes
All mailboxes installed on the road reserve are to be lightweight and frangible to ensure that vehicle occupants are not seriously harmed should a vehicle crash into them. Access to mailboxes should be constructed and maintained so they can be used in all weather conditions and to ensure their use will not damage or flood adjacent roads.
Roadside obstructions
No objects eg farm machinery or large rocks are to be placed on the roadside that could be a hazard to road users.
Standard of residential vehicle crossings without kerb and channel
All vehicle crossings/accesses onto a sealed road in the Rural Zone shall be formed and maintained to an all-weather standard and shall not result in the migration of material such as mud, stone chips or gravel on to the road. Where an access is used regularly, ie one that is used by vehicles on a regular basis including for the purposes of access to dwellings and buildings, the access shall be sealed for 1.5m from the edge of the existing seal.
Where material such as mud, stone chips or gravel is found to migrate onto the road, the first 5.5m of the access (as measured from the carriageway) or the full berm width of the adjoining road, whichever is the greater, shall be formed and sealed or paved.
Standard of rural unsealed road vehicle crossings without kerb and channel
All vehicle crossings/accesses onto an unsealed road in the Rural Zone shall be formed and maintained to an all-weather standard and shall not result in the migration of material such as mud, stone chips or gravel on the road. All weather standard means compacted level metal surfacing with a maximum particle size surface material of 20mm.
Standard of rural heavy traffic vehicle crossings
In Rural Zones heavy traffic accesses, including those for milk tankers and stock trucks, and any necessary extension of the carriageway width (on either side) shall be designed, constructed and maintained to carry the volume and weight of traffic likely to use the access. The surface of accesses onto a sealed road shall be sealed.
The access and carriageway extensions shall also be of sufficient area and width to provide for the swept path (turning area) of these heavy vehicles. (Refer to District Plan for heavy vehicle swept paths.)
Dimensions
The area to be surfaced shall cover the anticipated or existing vehicle swept path. See relevant diagram (below).
Drainage
All accesses shall be designed to ensure efficient drainage, and all storm water runoff shall be directed away from the road. Culverts with end treatment or concrete dish channel shall be provided where necessary and shall be designed and installed to the approval of the Roading Manager. The minimum culvert diameter is 200mm.
