It’s going to cost North Charleston about twice what was expected to heat and enclose the Danny Jones Pool and improve the recreation complex near Park Cirle, city officials have learned.

Efforts to turn the 1950s-era pool into a year-round swimming complex started about a year ago, prompted by Boeing executive and former world-ranked swimmer Marco Cavazzoni, who led a private fundraising effort that came up with $250,000 for the project.

North Charleston agreed to pay $750,000 toward the cost, but City Council members have been told that now, the city will need to come up with $743,463 more.
