A Topographic Survey is a plan view depiction of the relief of a parcel of land. This depiction may be accomplished either by contour lines or spot elevations. A Topographic Survey may be tailored to suit the needs of the client. The Topographic Survey may show contours at one, two or five foot intervals. A smaller the contour interval will result in more field measurements and higher cost. The Topographic Survey may be referenced either to a known benchmark somewhere near the project site or to an assumed benchmark established on site for this project. The scale of the Topographic Survey will conform to the needs of the client.
