This type of survey is critical to enable the design for adequate drainage of a site either before or after construction is completed. Elevations can be assumed relative to an arbitrary stable point (Bench Mark) or can be based upon a government identified sea level datum.

Our topographic surveys establish the change in grade or elevation of land and constructed features such as roadways, drainage channels and structures and are frequently utilized for design purposes. Specific costs relative to the construction of a foundation of a proposed structure or other improvements can be determined more precisely if a topographic survey is completed prior to design.
