Risk analysis of areas identified for potential future development

Located in Northland, the Kaipara region boasts impressive art, culture and heritage alongside stunning coastline views, all factors that have contributed to more demand for housing in the area. The Kaipara District Council identified multiple, large areas that they believe are next in line for potential development. ENGEO carried out a comprehensive geological risk analysis of the areas identified by the council for potential future development.

E
Engeo's Role

ENGEO produced a user-friendly, geological risk analysis of areas identified by the Kaipara District council for future development.

ENGEO’s methodology included undertaking high-level geomorphological mapping to evaluate Kaipara Districts surface and landforms. ENGEO incorporated detailed desktop studies of the mapped area’s geology, liquefaction potential, slope stability, acid sulphate risks, onsite wastewater disposal potential, consolidation settlement potential, historical uses and past development in its analysis of assessing geological risk. The risk calculations performed in GIS technology produced a gridded output of the overall risk for each of the potential development areas.

O
Opportunities

The project included opportunities for the ENGEO team to gain experience and an in-depth understanding of unique terrain in the Kaipara district. Working over multiple large areas our geologists gained excellent local knowledge in an area they had not worked in before, while also sharpening essential skills.

O
Outcome

ENGEO produced exceptional summary geographical data and mapping visuals. Using this information, high, medium and low-risk areas of geological hazard are now easily identified, thus creating a quick reference for future building consents within Kaipara. The reports ENGEO produced of the mapped areas are used as a reference for every new development in the Kaipara District.

ENGEO project team: Jake Cornall, Reuben Williams, Heather Lyons, Craig Wright, Richard Justice & Max McLean.
