Baltimore’s waterfront neighborhoods likely will be phased out of a state program that grants tax breaks for new development, but a grandfather clause would allow already planned projects to receive full enterprise zone benefits.

Companies must certify their projects with the city by June 14 to exercise the grandfather clause, said Mark Pollak, a partner in the Real Estate Department at Ballard Spahr.

“I’m not sure all that many people were aware of the possibility of the enterprise zone expiring or the fact that they could be grandfathered,” Mr. Pollak said. “I think this is a wakeup call for those who assumed it would carry on. If (companies) know their property no longer is within a proposed enterprise zone, they might want to take a look at the map of eligible areas and ask questions.”
