Have you received a FDNY violation, DOB or DOT violation as a result of your sidewalk curb box? Is your curb box a tripping hazard due to a sunken area or is it uneven with the surrounding grounds?
It is important to address the issue before you receive any additional fines or before someone injures themselves. You now should start seeking a contractor who is licensed, bonded and insured with the NYC DOT to perform this type of work. It is important to be mindful that the contractor must obtain all of the required NYC permits which will also be reviewed when the city reviews the possibility of satisfaction for your violation.
The process includes excavating the public sidewalk flag that has the curb box installed within. Typically a sidewalk flag is 4’x4′ in size and it is only this one flag that must be excavated and restored once your contractor has obtained all of the required permits. It is possible that the existing curb box may be adjusted and re-used however, it is more common that the entire curb box sleeve is removed and a new sleeve is installed over the curb valve. It is important the the new sleeve is set by a professional who has experience specific to setting curb box sleeves. The sleeve must be set to a specific height in preparation for the final concrete restoration.
It is very important that you have a NYC licensed master plumber inspect upon completion and confirm that the box is set safely and properly for future use of your curb valve.
