Before a street or sidewalk permit can be issued, a contractor must mark the location to indicate underground utility company lines such as gas, electric, water and cable. This is required by New York State law.
Once the street construction work is completed, the contractor is responsible for removing the pre construction markings.
Contractors or excavators can get assistance with locating underground utility company lines.
