Dense blocks, shared trouble

Many Newark homes are attached or closely spaced, with laterals running under sidewalks to the street. A collapsed lateral can mean opening the sidewalk and street, and a leak can undermine neighboring foundations. Getting a sewer camera inspection before digging keeps the opening small.
