ALTA/ACSM Surveys

ALTA:  American Land Title Association

ACSM: American Congress on Surveying and Mapping

ALTA/ACSM Land Title Surveys are surveys conducted usually prior to the issuance of a title insurance policy, which are sometimes required by lenders when dealing with commercial properties of significant values.

ALTA/ACSM Surveys can sometimes be among the most extensive and comprehensive types of surveys there are.  There are uniform accuracy and detail standards put forth by the ALTA and ACSM, which are meant to insure a uniform, quality product in all cases.  These requirements must be strictly adhered to.  In addition to these requirements, ALTA/ACSM Surveys also often include additional detail requirements such as the locating and marking of boundary lines, the depiction of contour lines, locating easements and encroachments, locating buildings and other improvements, and the locating of underground and above ground utilities.
