Key proposed changes for coastal erosion hazard in the new District Plan

  • Proposing to replace the existing map of the Coastal Hazard 1 line in the current District Plan with the newly identified coastal erosion area and map it in the Proposed District Plan as a Coastal Erosion Overlay.
  • This proposed coastal erosion area extends approximately 120 metres inland from the current shoreline and includes productive land, coastal wetland areas, coastal drainage systems and important coastal culvert structures. The area is similar to the existing Coastal Hazard 1 line for much of the district’s coastline, but extends further inland in some areas. The seaward boundary is the district boundary. The different coastal processes at Rakaia Huts mean that the proposed Coastal Erosion Overlay doesn’t extend into private property in the township.
  • Subdivision, use and development within the Coastal Erosion Overlay would be subject to rules broadly equivalent to current requirements of the Canterbury Regional Coastal Environment Plan, which landowners already have to comply with. However, once the Proposed Plan becomes operative all resource consents in relation to coastal hazards will be processed by Selwyn District Council and not ECan.
  • For properties in the Rural Zone, any subdivision or building a new dwelling in an area at risk from coastal erosion would be a non-complying activity. This means that a resource consent would be required and would be difficult to get.
  • Work on an existing building would be permitted under certain circumstances, ie as long as the risk from coastal hazards wouldn’t increase with the work.
