Reporting frequency: Quarterly
Core service: Community Preparedness and Response to Hazards
We provide the community with the most up-to-date information on contaminated land and natural hazards in our region so they can make informed choices about where they work, live and play.
As well as informing the community, this information plays an important role in the development of policy, land use planning and emergency management planning.
How are we tracking on our service measures?
Service measure 23: Percentage of natural hazards advice requests responded to within 10 working days
Target: 90% or more
How we are doing: 97% - 405 of the 418 requests have been responded to within 10 working days up to the end of quarter two.
On track
More information
We provide the public and territorial authorities with hazards advice on coastal, geological and flooding hazards in a timely way.
Land Information Requests include details of wells, resource consents, natural hazards and contaminated land impacting a specific parcel of land.
Flood Hazard Assessments are site-specific flooding assessments which are used as part of property transactions, subdivisions, valuations, insurance, resource consent applications and plan changes.
A fee is charged for producing these reports.
