What are Topographic Surveys?
Topographic surveys provide a three dimensional map with digital information about the land elevation and features. Topographic surveys are done for small residential lots as well as for multi-acre properties. Depending on the nature of the project, either a complete topo or a partial topo may be required. Topographic surveys may contain varying levels of detail including:
- Information such as elevations under a tree’s canopy, tree trunk location and size, pipe diameter, valve boxes, and drip line;
- Improvements including buildings, fences, roads, concrete, and utilities that are visible as well as underground utilities that have been located by the appropriate utility company.
- Differences in elevation on the surface are usually shown as contours which connect points of equal elevation.
- Spot elevations to supplement the contours at certain important points or intervals.
Why are they important?
CAD files generated by licensed land surveyors are used in the planning and implementation processes of various professionals:
- Civil engineers use topographical surveys to design and manage drainage for new construction involving single family homes as well as planned developments.
- Landscape architects often times encourage their clients to contract with a licensed land surveyor for a topographic survey so they have accesses to important information including the location of existing structures and trees, elevations at various points on the site, and utility lines.
