A task force has been established to examine costs of dealing with the mine subsidence in the Newcastle CBD and Lake Macquarie suburbs of Charlestown and Glendale.
Concerns have been raised by developers about the lack of information on the extent of undermining across the region.
Potential costs of remediation are a major concern, and Jodi McKay, Minister for the Hunter says mining is a huge issue in the region.
“It does very much impact on a developer’s decision to go ahead on a site, and we’re seeing that in the CBD of Newcastle," she said.
"So this taskforce has a life until September."
It has been welcomed by property owners and those who have land in the city.
"It is very much an issue we need to be able to address."
The taskforce will also have a representative from the Hunter branch of the Property Council.
Kristen Keegan, Hunter Regional Director says the problem is fairly unique to the area.
"There are not too many cities or areas in the world where they’ve mined an area and then decided to built multi-storey developments on top of that, so there are pockets of problems," she said.
"What this taskforce I’m hoping will do, is provide the mapping and certainty that developers need so they can come in and say, this site is good, we can invest in that, maybe this other site, it needs further remediation work."
