PEOPLE proposing to build in erosion-prone parts of beach-side Amity on North Stradbroke Island will have to erect a place that can either be easily relocated or face restrictions on the type of construction that will be approved.
The changes are in the draft city plan which was approved by Redland City councillors this week.
The change follows more accurate storm tide hazard mapping for the draft plan.
Mapping was in response to a raft of complaints from residents at upmarket places like Raby Bay and Aquatic Paradise many of whose homes were shown to be inundated under a year 2100 scenario.
This raised fears among residents about how this would impact on things like house insurance.
Redland Mayor Karen Williams said council responded to the feedback by engaging an independent expert to ensure the draft plan had the most accurate information.
Council received a total of 181 submissions during public consultation regarding flood, drainage-constrained land and storm tides.
“As a city of islands it is vital we have the latest information so we can ensure the city is resilient to coastal hazards such as erosion and storm tides,” she said.
“...The updated mapping shows fewer properties across the city with the potential to be impacted by flood or storm tides, particularly in our canal estates of Raby Bay and Aquatic Paradise.
“This result gives our residents greater confidence that their properties are safe.”
Cr Williams said the plan identified areas of potential storm tide inundation.
This meant planning could be tailored to ensure coastal areas were safe.
“A perfect example of this is in the coastal township of Amity, where we know coastal erosion is impacting on development in existing urban areas,’’ she said.
“The amended draft city plan responds by restricting certain development in these areas to structures that require a coastal location or temporary buildings that are able to be readily relocated.’’
Cr Williams said amended storm tide mapping was one of the most significant changes made from the original draft plan.
“We cannot control mother nature but we can plan for its impact, which is what this amended draft city plan does,’’ she said
“The new storm tide information and mapping is in line with the State Planning Policy, including considering the projected impacts of climate change.’’
Council has been asked for figures, showing the difference in flood impacted properties based on the latest mapping compared with the old mapping.
