Email address: A rough mockup of the proposed sign in the BMA packet. MANCHESTER, N.H. – A new digital arts display sign is coming to Cat Alley, and without an amendment to the proposed agreement that would put it there. In a 9-4 vote, the Manchester Board of Mayor and Aldermen (BMA) approved an “air rights” lease allowing the sign, which will be placed above the iconic Manchester alleyway at its exit point to the Elm Street sidewalk at 844 Elm St. Opposition to the sign was led by Anthony Sapienza (Ward 5), who voiced frustration with a lack of recourse held by the city if sign applicant and 844 Elm Street LLC Representative Liz Hitchcock decided to transfer her lease to another less trustworthy tenant during the lease’s 20-year term.
