Topographic Surveys

A Topographic Survey is required for determination of the relief of the terrain and to locate natural and cultural features on it. Spot elevations are taken on the property on a specified grid interval and are used as the basis for the engineering design of a Drainage Plan for the proposed development. Elevations and locations of adjacent roadways, paving, and structures are also obtained during this type of survey. At least one benchmark is set on site for future construction usually referenced to the North American Vertical Datum of 1988, unless otherwise specified. If requested, we can also generate contours on the survey at a specified contour interval (typically 1-foot) that provide a graphical depiction of how an existing grade is draining.

We can also locate utilities (storm, sanitary, water, gas, power, etc.) at this juncture of the survey that will aid in the civil utility design of the proposed development. This phase of the survey involves performing the necessary utility research at the state, county and/or city to compare field data to record information.
