Six Hundred Million Saved by Flood Defenses
Description
They’re investing billions to build a massive flood defense system for the Ōtākaro Avon River, aiming to save $630 million by 2060 and prevent homes from flooding. This isn’t a short-term fix — the Multi-Hazards Study, launched in 2017, models how climate change, earthquakes, and rising seas will compound flood risks over the next 30 years. City leaders stress that while the upfront cost is steep, the cost of inaction is far worse. Upgrades over the next decade will handle the next 30 years, but beyond that, even higher defenses could avoid $2.2 billion in damage by 2100 — a long-term battle against rising waters.
