“Topo” surveys record property features in three dimensions. The use of elevation allows for land contours to be determined - a crucial factor for many land uses, especially with regard to drainage. Natural and manmade features are also noted such as embankments, ditches, trees, and bodies of water. Data gathered from a detailed topo survey is an important resource when planning improvements to a given piece of land.  Marsh & Legge has had extensive experience with large topo surveys within Virginia’s state parks, and with smaller topo surveys conducted for various commercial and residential properties.
