"It requires contractors to work with the City's Office of Employment Development [to] match employment with qualified city residents. And there's always room for improvement."
Joann Logan, a spokeswoman for the Baltimore Development Corp., said the organization has not yet reviewed Young's proposal, and couldn't comment on it.
