The clean-up of West End’s contaminated Orleigh Park could see as much as 13,500 square metres of soil removed along with several trees, Brisbane City Council says.

Last year, tar was found to be present in the majority of the park and some surrounding streets, as the park previously housed a coal tar processing facility, which closed in the 1980s.

Council projected the total cost of the remediation works as just more than $15 million between 2018 and 2020, according to its 2018 budget.
