Diana DiZoglio and Bruce Tarr and Reps. Lenny Mirra and James Kelcourse wrote to Energy and Environmental Affairs Secretary Kathleen Theoharides last week, seeking a severe weather emergency declaration. “This must be addressed as soon as possible,” the letter said. “We can use the example of what is happening in the Reservation Terrace area of the City of Newburyport as a reference of why immediate action must be taken. Residents there are seeing major flooding of their homes and destruction of their property. If we do not act quickly, we are going to see history repeat itself in Salisbury.”
