Flag The individual concrete square that makes up a sidewalk, typically five feet by five feet in NYC, separated from neighboring flags by expansion or control joints.
Flags are the unit DOT works in for nearly every purpose: a Notice of Sidewalk Violation cites specific numbered flags on its diagram, contractors price repairs per flag or per square foot, and a defective flag must be replaced in full rather than patched. Because DOT requires full-depth replacement of a cited flag rather than a surface patch, an owner can't satisfy a violation by resurfacing just the top layer of concrete. Knowing your flag count up front is one of the fastest ways to get an accurate repair quote.
Frequently Asked Questions About Flag
What is a sidewalk flag?
The individual concrete square that makes up a sidewalk, typically about five feet by five feet in NYC, separated from neighbors by joints.
Why are flags important to violations?
DOT cites specific numbered flags on the violation diagram, and contractors price repairs per flag or per square foot.
Can a cited flag be patched?
No. DOT requires full-depth replacement of a cited flag. Resurfacing only the top layer does not satisfy the violation.
Are all flags the same size?
Five by five feet is the common standard, but frontage layout, driveways, tree pits and corner geometry produce partial and irregular flags.
How does flag count affect price?
