Turning heads will be required at the end of all no-exit roads in accordance with Austroads Rural Road Design. Page 3 5.0 GEOMETRIC DESIGN Geometric design, including gradients, super elevation and road widening shall be in accordance with the Austroads publication “Guide to Geometric Design for Rural Roads”. 6.0 WALKWAYS Rural residential subdivisions should make provision for pedestrian access along grass berms. Refer to the relevant district council’s Table 3.1 appended to this Part or the District Plan. 7.0 ROAD RESERVES AND FENCING Adequate width of road reserve is important and is normally 20 metres. Additional width is likely to be required where earthworks are extensive. A minimum clearance of 3 m is desirable between the road reserve boundary and tops of cuttings or toes of embankments.

On steep grades where channels are subject to scouring, protection work may be required. Swale drains may be allowed in suitable locations in some district – refer to relevant district council for information. 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 Page outlet, the construction of drilled and lined soak holes and/or roadside berm drainage beds 4 are an option. 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. 11.0 BRIDGES Where bridging is required, the design shall comply with NZ Transport Agency standards and requirements. Approval of waterway area shall be obtained from Environment Waikato and the bridge design shall be prepared and certified by a Chartered Professional Engineer. Design calculations shall be provided to Council. 12.0 INTERSECTIONS The location of intersections shall be chosen to ensure adequate spacing and sight distance is available for all vehicle movements.
