Heavy equipment and construction workers will roll in to peel up the asphalt, do some digging, pour a foundation and start putting up steel. In a couple of years, the 200-apartment first of three buildings in Phase 1 of the site’s redevelopment, to be known as “Square 10,” will appear. Clay Fowler, founding partner of Spinnaker Real Estate Partners and principal of LWLP New Haven LLC, to which the city transferred ownership of the property last month, said, “We couldn’t be more pleased or more excited to be here.” Spinnaker took over the project in August 2019 after the initial developer, Live Work Learn Play, a Montreal company that started the plan in 2013, withdrew after six years, faced with complications related to potentially moving utility lines and putting up a hotel that didn’t cost out. The total construction price for Phase 1A is expected to be $76 million, with the costs of the later phases still to be determined, city spokesman Len Speiller has said. Estimated completion dates are 2025 for Phase 1A and 2027 for phases 1B and 1C.
