Following the April 2018 flood, an Independent Review made comprehensive recommendations to improve the flood risk management of the Ngongotahā Urban Area.
The Ngongotahā Flood Mitigation Project was established as a joint Rotorua Lakes Council and Toi Moana Bay of Plenty Regional Council programme of action to implement the recommendations.
In conjunction with the Ngongotahā Community Reference Group, the project team has identified potential options to mitigate the flood risk.
The flood mitigation plan is to implement a combination of wider catchment works (tree removal and detention bunds), stop banks, high flow bypasses and overflow channels. The work is planned over a 2 year period with the catchment works beginning early 2020. The civil works will follow consultation with impacted property owners and confirmation of the detailed design.
