Public campaign starts

by Ann van Engelen

Selwyn District Council has started informing landowners of the latest findings on flooding and coastal hazard risks, and how it’s proposing to manage them in the new District Plan.

“The council, with the help of Environment Canterbury, has carried out computer-based flood modelling to predict the extent and depth of flooding that could happen during a one-in-200 year and a one-in-500-year flood,” says SDC’s group manager Environmental and Regulatory Services, Tim Harris.

“As a result of having to assess the risk from flooding in a 200-year flood event, a much larger area of the district has now been identified as being susceptible to flooding. While the biggest change from the current District Plan is the size of the district that is affected in some way, we are proposing to manage flood risks with similar restrictions to what’s in the current District Plan.”

The main change council is proposing is new dwellings built on affected areas would be required to have a higher minimum floor height. For the majority of properties, the increase is likely to be only a few centimetres.

“The council is expecting to notify the Proposed District Plan for formal public consultation by the middle of this year, when people will have the opportunity to make a submission on any of the proposed provisions, including how the flood and coastal hazard areas are mapped.”

It’s expected that the new Proposed District Plan will be fully in place by mid-2022, subject to any Environment Court appeals. Until then, the current rules for building and resource consents continue to apply.
