DAYTONA BEACH — If you've been in COVID-19 hibernation and haven't come out much over the past year, you're going to find part of the downtown riverfront almost unrecognizable. The northern end of the park that runs along the western bank of the Halifax River has been undergoing a $25 million transformation over the past 10 months, and the recreational space is starting to offer glimpses of the esplanade it will become. Dozens of replanted mature trees are settling into their new home, sprawling retention ponds are being carved out, and berms are turning the once-flat expanse into artful waves of rolling land.
