Vertical Information

This month we continue with a commercial real estate blog series that covers each item in an ALTA survey checklist, otherwise known as TABLE A. We will look at the benefits of each point in detail. An ALTA survey is typically utilized for commercial and industrial properties only. The requirements to perform an ALTA allow for several additional features to be added to the typical boundary survey.

  1. Vertical relief with the source of information (e.g., ground survey, aerial map), contour interval, datum, with originating benchmark, when appropriate.

Any time you hear the word “vertical” it implies a topographic survey. The purpose of the topographic survey is that it shows the highs and lows of a property which can be extremely helpful to understand how the lot will drain when it rains or will assist with the development of a lot in knowing how much fill dirt would be needed to make the lot level. It can also assist in the construction of sewer lines and other utility related lines. In most instances the vertical data provided will be tied to a local benchmark that can be utilized by an engineer for design services.
