Last week intrepid Chronicle contributor Steve Fisher of Middle Village came across a city crew doing test borings for future sewer pipe installations along Penelope Avenue and 74th Street, above. As the retired architect, accomplished photographer and essayist often does, he put on his reporter’s hat to find out what the men were doing.
What they were doing was drilling deep, and deeper, seeking to find out how far down they’d have to go to reach soil stable enough to handle the project.
Chris Chaillou, the crew leader, told Fisher his workers had gone down 27 feet so far, and might have to reach 50 or 60 feet to get the stability required for sewer lines. Chaillou said he expects the crews to drill 60 or 70 holes as part of the study before pipes can go in. He could not offer a timetable for when the actual installation might begin.
Manhattan is mostly granite. Queens is not.
