City Council Chief Planning Officer Liam Hodgetts has stopped the consultation after City Councillor Tony Randle brought to his attention a technical error in the equations of the benefit cost ratios (BCR) outlined in the draft plan.
The error discovered by Cr Randle has been verified by City Council officers and an independent review by a transport economist.
Mr Hodgetts says the calculation error adjusts the safety figures for under-reporting twice rather than once, resulting in an overstatement of the safety benefits being used in the BCR that was an input into your decision-making in April. This error has a significant effect on the BCR values presented to the P&E Committee in April.
“To find a mistake in the BCR that was externally and independently peer-reviewed is very disappointing and I apologise for the error - this should not have happened.”
Wellington is still required to meet the terms of the Land Transport Rule: Setting of Speed Limits 2022 rule.
Mayor Tory Whanau is also disappointed that the error occurred.
“Elected officials rely on the accuracy of information from council officers in making decisions, and the public when they submit their views as part of the consultation process. In this case, accuracy was lacking. We have reviewed the situation to ensure it doesn’t happen again.
“I do want to express my support of Council officers. They have a big workload dealing with complex issues. While they get it right most of the time, they are only human, and errors do sometimes happen.”
Staff intend to schedule a workshop and briefing for elected members in August to discuss a new approach, including the parameters of a new speed management plan, how it will proceed and how it will ensure the transparency and rigor of the process.
In the meantime, officers will be contacting submitters – to apologise and to explain the next steps in this process.
