Topographic Surveys

Topographic Surveys

To locate topographic features of land—natural and/or man-made — such as building improvements, fences, elevations, trees, streams, and contours. A topographic survey displays three dimensional features onto a two dimensional grid. This type of survey may be required by a governmental agency or may be used by engineers and/or architects for the design of site improvements or developments.


Reasons for a Topographic Survey:

  • Building a home
  • Existing conditions for a future design and development

Featured Project

Steigerwald Lake National Wildlife Refuge

Statewide contracted with the ESA Vigil-Agrimis to supply supplemental ground mapping data along with aerial mapping data of over 1200 acres of the Steigerwald Lake National Wildlife refuge. The purpose of the survey was to support the environmental assessment to restore floodplain connectivity to the Columbia River. The project would help improve habitat and benefit steelhead and cutthroat trout, chinook, coho, and chum salmon, and Pacific and western brook lamprey.
