Service Description: Whangārei District Council holds indicative information on land stability hazard for Whangārei. The Whangarei District Council may require site-specific investigations before granting future subdivision or building consent for the property, depending on the level of stability risk of the area the property is in.

Title: Land Instability Update 2022
Author:
Comments: This landslide susceptibility assessment is intended to be a high-level tool for identifying areas that are susceptible to land sliding across the District, based on mapped landslide and instability features and the relationship between geology and slope angles. The updated mapped susceptibility zones can be considered analogous with the Low, Moderate and High “land stability hazard zones” as outlined in the EES (Whangarei District Council, 2010, “Environmental Engineering Standards”), and the information, assessment and reporting requirements stated in the EES will continue to be suitable for the updated mapped land in the District. This susceptibility assessment does not remove the requirement for site specific assessment at the time of subdivision, change in land use, or building works that would require consent in a site suitability report. Updates to the District Plan may also require site specific assessments for other activities. Site specific assessments are required to be undertaken by a geotechnical professional to confirm the susceptibility class and the suitability of each site for development. The map should be read in conjunction with the T+T report dated October 2020, reference 1012149.3000: "Landslide Susceptibility Assessment for Whangarei District Council". Refer to the report for further detail and applicability limitations:https://www.wdc.govt.nz/files/assets/public/v/2/documents/council/reports/hazard-reports/land-stability/landslide-susceptibility-technical-report.pdf
Subject: This map contains data that is part of the report "Landslide Susceptibility
Assessment for Whangarei District Council" prepared by T+T for WDC in 2020. Refer to the report for further detail and applicability limitations.
