More than 1.3 million square feet of retail space had to be completely removed, and construction workers had to tread lightly atop a working car park.

More than 1.3 million square feet of retail space had to be completely removed, and construction workers had to tread lightly atop a working car park.

Still, plans for Columbus Commons, the nine-acre park on the former site of City Center, remain on schedule.

"We had some nice days in the winter, but we've had some rainy days in the spring," said Amy Taylor, chief operating officer for Capitol South Urban Redevelopment Corporation, the primary force behind the project.

The park will open in December. Seasonal plantings will hit the ground in spring 2011, with activities set to start soon after.

Inspired by places like Bryant Park in Manhattan, the space will feature flower displays, shaded picnic areas and open lawns to accommodate art and music.

"I think there is hopefully room for most ideas," Taylor said. "The grand lawn is going to be spectacular, so it will allow programming of all types."
