Each project has special needs and requirements.  In an effort to clarify the different types of land surveys, here is a list of the most common types of surveys and what they encompass.

Improvement Location Certificate

Usually required by lenders on residential loans, or by a Town or County Building Department during construction.  A map showing the boundaries of the property and the major improvements (buildings)thereon.  It is not to be used for the establishment of fences, buildings, or other future improvements.  Monuments are not set at lot corners.

Land Survey Plat/Boundary Survey

A survey reflecting the boundaries of a parcel of land showing: recorded and apparent rights-of-way, easements and encroachments; a description of all monuments which mark the boundaries of the property and of all controlling monuments used for the survey, as well as any conflicting boundary evidence; and general locations of major improvements located on the property.  Missing monuments will be re-established.  Per state statutes, a mylar copy of this survey must be deposited for record with the County Surveyor within six months and a recording fee is required.

Improvement Survey Plat

This is also a Land Survey Plat except that this survey reflects a more detailed location of all structures, visible utilities, fences, walls, walkways, driveways, roads, and other improvements situated on the property.

Topographic Survey

A survey showing the physical features of a parcel of land including improvements, trees, roads, driveways, elevations, contours, utilities and other significant features.  This type of survey is generally required for design purposes by architects and engineers.

ALTA/ACSM Land Title Surveys

A survey based on standards adopted by the American Land Title Association in conjunction with the American Congress of Surveying and Mapping.  The scope of this type of survey varies but it is generally required by lenders for larger commercial properties or tracts of land.  A standard ALTA checklist (Table A) of optional items to be included in the survey should be submitted to the surveyor along with a copy of the current title work.  Setting missing monuments is optional.
