To plan for sewer and stormwater improvements, it is necessary for survey crews to collect various information about a proposed construction area. Survey crews take a variety of measurements to determine public right-of-way boundaries, private property lines, public sewer easement boundaries, the presence of utility vaults and other landmarks, and other necessary measurements.

You may see survey crews standing on sidewalks and streets in front of properties in the neighborhood to measure the elevations of the first floors of houses or buildings and see if they have basements. This is necessary to obtain measurements of private sewer depths and will help engineers design a sewer system that will maximize gravity service.
