Stormwater projects

Earthquake damage has led to an increase in the severity of flooding to existing flood-prone land and some new areas.

We’re working in partnership with the local community to restore the health of the Cashmere Stream.

The Estuary and Sumner Flood Protection Programme includes Southshore, Redcliffs and parts of Sumner.

Earthquake damage to land and infrastructure alongside the Heathcote River has led to increased severity of flooding.

Work on the Hoon Hay Stormwater Basin is now complete.
