Topographic land surveys are used to identify the characteristics of a parcel of land and measure their relative position. This includes mapping surface contours as well as existing surface features and buried utilities.
A topographic survey can include property lines, easements, right-of-way, streets, walkways, manholes, retaining walls, buildings, trees, and other features useful for property development and management purposes, and results in a topographic map showing contour lines and benchmarks to relay elevation and surface area data.
Features are both vertically and horizontally referenced according to the needs of the project and each feature is displayed relative to a standard coordinate reference monument known as a ‘benchmark’. These details will allow the developer to plan and design their development as well as to better understand the site conditions that could delay and/or cause issues during construction.
