- Summary
- Key findings • Assuming that existing seawalls are not replaced in the future, or no alternative protection measures are implemented, the Paekākāriki shoreline is projected to be susceptible to coastal erosion over the next 30–100 years. • In general, existing seawalls currently provide good protection from coastal erosion, but the beach in front of them could lower 0.8 to 1.4m over the next 30 years as a result of relative sea level rise (RSLR), which could cause them to fail. • Paekākāriki is the second most vulnerable area in the district based on the number of private land parcels potentially affected by coastal erosion. • Paekākāriki is less susceptible to coastal flooding due to the higher land elevation of this section of coast. Flooding is localized to the Wainui Stream and Waikakariki Stream mouth areas.
