<strong>Project</strong> <strong>Hurunui</strong> <strong>Wind</strong> <strong>Construction</strong> Effects <strong>and</strong> Management Report<br />
Table 2 indicates the typical access road cross sections for the different terrain types with<br />
cut slopes expected in the region of 1H:2V to 1H:4V. Fill slopes, where applied, are<br />
expected to be in the region of 2H:1V as tabulated in Table 3. Typical cross sections are<br />
illustrated on Drawing Sheet 10. Drawing Sheets 8 <strong>and</strong> 9 illustrate the sections of access<br />
road where these typical cross sections apply. The longitudinal extent of cuttings (length<br />
along the access roads) can be approximated to the linear length of each section identified.<br />

Typical cut heights of 2.5m to 6m described in Table 2 will be similar in scale to some of<br />
those visible along the existing tracks. Photograph 6 in Appendix B illustrates such a cut on<br />
the existing track following the proposed alignment of the northern access road.<br />
Photographs F9 (taken at project Te Apiti) <strong>and</strong> F10 <strong>and</strong> F11 (taken at <strong>Project</strong> West <strong>Wind</strong>) in<br />
Appendix F illustrate road cuts with approximate heights between 7m to 8m.<br />
Table 4 summarises sections where extremities of cut height are expected (ie batter heights<br />
greater than or equal to approximately 6m.<br />
