Mayor Donna Holaday has scheduled an open discussion regarding the future of the central waterfront. In a letter she sent to the City Council, she said she wanted to provide city leaders — including Newburyport’s five new city councilors — information “regarding all aspects of the redevelopment options, so that further progress can be made toward the creation of a larger and more vibrant central waterfront park which is better connected to our historic downtown.” The discussion is scheduled for 7 p.m. Feb. 5 at City Hall auditorium. Development of the central waterfront has been an issue of debate in Newburyport for many years. However, the City Council has had little input in the discussion because the land is owned by the Newburyport Redevelopment Authority, not the city. Authority members are expected to attend the meeting.
