Service Description: This dataset identifies areas susceptible to static coastal inundation under future extreme sea level conditions. The mapping supports climate adaptation and long-term planning by showing areas below projected water levels using a bathtub model adjusted for sea level rise and vertical land movement.

Description: This dataset presents the extent of static coastal inundation under possible future sea level rise scenarios for multiple Annual Exceedance Probability (AEP) events. The mapping identifies low-lying areas susceptible to flooding from elevated sea levels due to tides, storm surge, and projected sea level rise.
Copyright Text: Developed by Tonkin & Taylor Ltd for Nelson City Council and recorded as Nelson Coastal Inundation Mapping Update, Phase B (v1), December 2024. Derived from 2021 LiDAR data and NIWA (2018) storm tide levels, adjusted for sea level rise and vertical land movement. Mapping uses a bathtub approach and does not account for overland flow paths, engineered structures, or future shoreline changes.
