What does the Topographical Bureau do?
Reviews ULURP Mappings
The Topographical Bureau reviews all City Planning Commission ULURP (Uniformed Land Use Review Procedure) mappings. Whenever an alteration to the city map is made, our office reviews the map change to make sure that the map conforms to the standards set by our office.
Provides Surveyors with Benchmarks and Monuments
The Topographical Bureau provides surveyors with Benchmarks and Monuments in order to help them accurately survey a person’s property. This information provides both horizontal and vertical control, which allows the surveyor to find the city’s property line in relation to the private owner’s property line.
