New York City is making a top secret map of everything under the street - Gothamist

New York City is developing a top-secret map of its underground infrastructure to avoid costly delays and improve safety. The project, funded by a federal grant, aims to create a comprehensive map of water lines, electrical conduits, and natural gas pipelines. The map, inspired by similar systems in Singapore, Tokyo, Flanders, and the UK, will be accessible only to authorized city officials on a need-to-know basis.
