Plan Change 42 – Mangaroa and Pinehaven Flood Hazard Extents


A hearing for Plan Change 42 will be held  27 – 28 September 2017, with 29 September 2017 being a reserve day.

Further submissions closed on 8 June 2017 at 5pm. Further submissions are available in the table below.

The Resource Management Act 1991 and the Wellington Regional Policy Statement requires that councils addresses the risks associated with natural hazards. Plan Change 42 addresses the risk from flooding within the Mangaroa River and Pinehaven Stream catchments for the 1:100 year flood event.

The current District Plan objectives, policies and rules do not recognise the identified Flood Hazard Extent and associated risk to development for either the Mangaroa River or the Pinehaven Stream. Consequently, further development undertaken in accordance with the existing District Plan provisions within either of these Flood Hazard Extents could unacceptably increase the risk to people and property from flooding.

The plan change identifies a range of risks associated with flood events in both the Pinehaven Stream and Mangaroa River catchments. The proposed provisions seek to avoid development in the high hazard areas and avoid and mitigate the risk from flooding in the lower hazard areas.
