The Joint Regional Planning Panel has approved a $25 million expansion at Jamberoo Action Park, despite passionate objections from residents and Kiama Municipal Council.The panel last night gave the controversial theme park upgrade the green light after imposing numerous additional development conditions, including stipulation on the colour of the new rides.The five-member panel's unanimous decision failed to impress either the developer or concerned Jamberoo residents.Jamberoo Action Park managing director Jim Eddy said he was disappointed the panel had not agreed to several changes to the proposed conditions.The park will now seek legal advice about its best course of action."We will now consider it, we'll seek legal advice and see what our options are and then pursue those options that best fit our future objectives," Mr Eddy said.He added that many residents' concerns about traffic at the park were "nonsense"."The only problem we've ever had with traffic is we haven't had sufficient car parking to accommodate the cars that come to the park," he said.The expansion, to be known as Kangaroo Island, includes seven new water-based rides, a 1700-lot car park and alterations to the park entry.But Kiama's deputy mayor Ben van der Wijngaart said the council would never have approved the proposal."We didn't believe that the impact of the traffic management issues had been addressed adequately and whilst there were some amendments which we were pleased with ... I do not believe that the traffic issue has been addressed," he said.Kiama Municipal Council held a last-minute meeting on Tuesday and decided to oppose the development.Jamberoo resident John Malouf, who lives opposite the theme park, was dismayed at the decision."There was no mention of the potential danger of emergency traffic being able to negotiate the narrow road in case of an emergency," he said.Mr Malouf and others argued increased visitors to the valley would make the narrow Jamberoo Rd even more dangerous.Residents also argued the theme park was already big enough and the expansion would stand out in the valley."No-one wishes to close it down but its days of incremental creep must come to an end," said Ron Murrell.Regional panel chairman Allen Grimwood said the application had been approved because it would bring "significant benefits to the region ... through increased visitation.""The conditions have been amended and altered to ensure that the concerns of the residents are also considered," he said.Mr Eddy said the expansion would create an extra 100 jobs.The park will need to get a construction certificate before development begins.
