There is a 8-10 inch by 4 inch hole in the pavement surrounding the catch basin on the corner of Boylston Terrace and Brooks street. It seems like the pavement fell into the basin and the pavement around the hole is not secure. It's a potential hazard for walkers, pets and especially if a car parked on it.
