TYPES OF SURVEYS

(July 2024)

There is a wide variety of mapping and measuring activities performed by surveyors. Here is a brief description of several survey types:

ALTA/ACSM Survey

A comprehensive land survey performed at the written request of banks, and other residential/commercial lenders. The survey request must be accompanied by all deeds and easements that affect the property to be surveyed as well as those that affect immediate neighboring properties. The survey should contain the items that are required by American Land Title Association and America Congress on Surveying and Mapping standards, such as boundaries, indication of true north, drawings done to proper scale (with scaling identified), map oriented to north, created on paper no smaller than 8.5 by 11 inches, identifying information of person performing the survey, etc.

Bathymetric Survey

Refers to mapping and measuring underwater areas, specifically seabeds.

Boundary Survey

A survey of the boundary of property according to the information appearing in the applicable, recorded deed. Improvements along the boundary that affect land use or property title are located (building, drives, fences, other structures, utilities, etc.). Improvements in the interior of the boundary do not typically appear in the survey map.

Cadastral Survey

A resurvey of lands located in the United States’ Public Land Survey System that is made for the restoration of property lines.

Construction Survey

 A survey to determine and physically mark (stake out) the location of roads, structures, utilities, land grading, etc.

Control Survey

A survey that establishes accurate horizontal and vertical points to facilitate aerial photography, boundary determinations, construction staking (marking) and mapping.

Court Exhibit Survey

See judicial survey.

Easement Map

A survey or map that indicates the position of existing or proposed easements with existing boundaries, improvements, features (such as buildings driveways, roads, surface utilities, visible bodies of water) other record easements and unresolved conflicts with record deed descriptions and maps. Such surveys must include information on the category of Boundary Determination used in the survey.

Elevation or Floodplain Survey

A survey that establishes a building’s or a parcel of land’s elevation to determine whether a property is in a flood zone and to assist with construction plans.

Existing Building Location Survey

A type of survey which depicts or notes the position of all buildings on the property with respect to boundaries, record easement lines, pertinent municipal setback requirements and deed restrictions. No other improvements or features are required to appear in the survey.

Geodetic Survey

A survey, typically of a large or unusual land area as well as shorelines, which must include information on the earth’s curvature as well as astronomical observations.

Hydrographic Survey

Where data is collected on a body of water such as depth, bottom contours, current movement, water levels, and various navigational markings. It can be used for maritime purposes or for engineering or power plant projects.

Improvement Location Survey

Like a zoning location survey, it indicates the horizontal and vertical positions of improvements (both existing and proposed) with respect to municipal or statutory requirements. Only features that are of concern need to appear in such surveys.

Judicial Survey

A survey of legally filed descriptions and maps that a court orders to prepare an exhibit that is to be used in a courtroom.

Location Survey

A type of survey that is usually required during property loan transactions. It is a boundary survey that also includes location (marking) of all the property’s interior improvements. During surveying, missing corner markers are replaced and a map showing the boundaries and improvements is prepared.

Lot Survey

See site plan survey.

Lot Split Survey

Surveys performed when a site owner wishes to divide the parcel. The process creates new plats and legal descriptions for proper registration.

Mark the Property Survey

A stripped-down version of the Boundary Survey where a surveyor merely locates and places stakes at the four corners of a given property.

Mining Survey

A three-dimensional survey that locates and documents a given underground area, including all natural and artificial (man-made) features.

Mortgage Inspections

These are inspections, not surveys, which are usually part of a mortgage loan application process. They are NOT sufficient to rely upon for any construction or site improvement project.

Mortgage Location Survey

Refers to surveys used by lenders and title companies to clear a property of encroachments on neighboring properties or easements. Again, they help facilitate loan and title processing but ARE NOT legally sufficient to support property use decisions.

Plot Plan Survey

See site plan survey.

Site Planning Survey

A combination of boundary and topographic surveying to create a starting point to allow for site improvements. Also used for obtaining permits.

Subdivision or Re-subdivision Survey

A type of survey used, primarily, in construction and land recording. It includes a topographic survey of land that will be divided into smaller parcels.

Subsurface Survey

See mining survey.

Topographic Survey

A survey that identifies land features such as its contours, elevations, grades, embankments, depressions, courses of water, roads and utilities.

Torrens Survey

See judicial survey.

Wetlands Delineation and Locations Surveys

Wetlands are, essentially, any areas that are inundated with water for, minimally, two weeks during a growing season. There are a plethora of laws and regulations concerning wetlands, focusing on their protection. A host of factors, such as soil observation, erosion patterns, hydrology, vegetation, etc., helps to determine the existence of wetlands. Once boundaries of wetlands are determined, this information is made available so that any private or public construction being proposed (and permitted) near such areas can take the wetland’s existence into proper consideration.

Zoning Location Survey

This survey indicates the position improvements (both existing and proposed) with respect to applicable municipal setback requirements. Its purpose is to either assure or to attain compliance. The survey usually only shows the area of property affected by compliance concerns.
