Any excavation in a NYC street requires a DOT street opening permit. These permits regulate when, where, and how streets can be opened for underground utility work. The permit process involves submitting an application with detailed work plans, paying fees based on the street classification and excavation size, and complying with restoration requirements. DOT has specific rules about work hours, traffic management, and street restoration standards. Permit fees range from $1,500 to $5,000 or more. There are also moratorium streets where recent paving prohibits new excavation for a set period. Sewer & Water Pros handles all DOT permit applications for our clients.
