Alexandria officials will break ground Saturday morning for a long-awaited city park at the foot of King Street, days after the demolition of the Old Dominion Boat Club, which blocked public access to the Potomac River for decades.

The groundbreaking signifies an interim step in the development of Fitzgerald Square, the centerpiece of Old Town’s long-planned waterfront revitalization. It could be another decade before flood mitigation measures are completed and the final park takes shape, city documents say.

The park and waterfront revitalization have suffered several delays, from lawsuits to slower-than-expected construction by developers. The city bought the boat club site for $5 million in 2014, after four decades of disputes and an agreement to swap land for a new clubhouse one block south. That facility is constructed and open.
