Section 32 Analysis of Criteria (474kb)
For this analysis, the criteria adopted by Gisborne District Council for assessing coastal hazard areas (Appendix I) are used as the basis for evaluating the potential alternatives according to the general requirements of S.32 of the Act. For the evaluation, the relevant provisions of The New Zealand Coastal Policy Statement 1994 (NZCPS-94) are used as a guideline. Because of its relevance, a brief history is given of coastal hazard mapping in the Gisborne district.
