Potential Runway Extensions Potential to Extend to 1,950 metres: There is potential to extend the primary runway to 1,950 metres Sealed length, while leaving the same length of unsealed end perimeter as at the southwest approach Map drawn using TUMONZ   Gully 1: The runway cannot be extended without crossing the gully at the northeatern approach. Volume of hardfill reqired: c. 46,060 m3 Extension of the runway to point that the perimeter encounters a terrace on its southeastern edge (see “Terrace Edge” above) would extend the sealed length capability by 305 metres to 1,612 metres (measurements made using TUMONZ and Google Maps). To Extend to 1,612 Metres Sealed Length: Extension of the runway to point that the perimeter encounters a terrace on its southeastern edge (see “Terrace Edge” above) would extend the sealed length capability by 305 metres to 1,612 metres (measurements made using TUMONZ and Google Maps). Stripping 305 x 145 x 0.75:   33,169 m3 Hardfill, including runway top-course, applied to “Gully 1” and to replace stripping: Gully fill:   48,060 m3 Stripping replacement:   33,169 m3   83,129 m3 To Extend to 1,950 Metres Sealed Length: To fully utilise the Hokitika Airport property and the terrace top as far as HauHau Creek a relatively modest amount of stripping and backfilling will be required. Stripping 626 x 145 x 0.75:   68,078 m3 Hardfill, including runway top-course, applied to “Gully 1” and to replace stripping: Gully 2 & Terrace Edge fill:   79,450 m3 Stripping replacement:   68,078 m3 147,528 m3 Gullies & terrace edges to be filled Significant earthworks required will be stripping (vegetation, soils & soft earth) probably less than 1 metre depth, and backfilling of gullies and terrace edges.
