A legal stoush between the Whangarei District Council and an engineering company over the failed Marsden City development has been settled but the details are confidential.
In 2015, WDC filed a civil case in the High Court to try to recoup about $8 million from companies, including civil and structural engineers Cook Costello, it says were responsible for signing off the new development's faulty infrastructure.
Cook Costello designed and oversaw the construction of the development.
The story behind the once-hyped Marsden City development, which promised 2200 homes alongside new businesses and industry, soured in April 2014 when it was revealed that sections of the waste and stormwater systems vested to WDC had failed and would cost ratepayers millions to repair.
The unforeseen effects of acid sulphate soils were to blame, WDC said, and it now had a new process for assessing the risk from this type of soil.
