New Haven is abuzz over an announcement slated to come tomorrow morning that city officials said will “dramatically change New Haven and the region.”

In a Monday morning press release, City Hall spokeswoman Jessica Mayorga called the announcement, which will be made at 9:30 a.m. at the Cooperative Arts and Humanities High School on College Street, “the most significant announcement ever made in New Haven.” Mayorga wrote in the release:

At this event, a groundbreaking announcement will be made that will answer the questions: ‘What makes a city great? What does it take to help move an entire city forward into a new generation? This will be an announcement of national interest that will change New Haven and the region forever.

To prepare for the announcement, the city has even created a Tumblr blog called “Our New Haven” with the message “we make greatness happen: each one of us.” The Tumblr also features a clock counting down to the 9:30 a.m. announcement.
