Often, when improvements are made to a property , a topographic survey may be required. A Topographic Survey map consists of everything a Boundary Survey map contains but it also details the contours of the ground and is used to determine a various number of things such as the amount of soil to be displaced in a particular project (earthwork calculations), the effects rainfall has on a particular property and its adjoining lands, and is generally the base mapping for any building site, large or small.
