A Boundary Survey is a procedure by which a Professional Land Surveyor establishes the corners of a parcel of land. A Boundary Survey is the interpretation of evidence. Surveyors are fond of saying “Monuments over Measurements.” This simply means that there is only so much room on the surface of the earth. Think jigsaw puzzle, everyone’s property must fit! Therefore, the distances that are indicated in your deed are only a small part of the puzzle. It’s what fits on the surface of the earth that counts.
Minor Land Division (MLD) Surveys
The purpose of a Minor Land Division (MLD) is to allow for the division of land into two or three tracts or parcels when a plat is not necessary.
Boundary Survey (ALTA)
The American Land Title Association or ALTA, is a national trade association representing the interests of the abstract of title and title insurance industries.
An ALTA survey is a boundary survey prepared to a set of minimum standards that have been jointly prepared and adopted by the ALTA/ACSM. Additionally, an ALTA survey shows improvements, easements, rights-of-way, and other elements impacting the ownership of land. An ALTA Survey is often prepared for commercial properties, as it will provide the title company with the information required to insure the title to the land and improvements to the high degree that a commercial development may require. In addition to the minimum standards set forth, a table of optional elements is included in the ALTA/ACSM standards. A careful review of the elements from the optional "Table A" is helpful in delineating a clear scope of the land surveyor's services.
A current title commitment is required before an ALTA Survey can be completed. The surveyor will refer to the title commitment for the legal description of the property and for the legal description of any encumbrances (exceptions). Areas of ownership, improvements, and encumbrances will be shown graphically. If the survey discovers any encroachments, they should be shown graphically, and a note indicating the nature of the encroachment may also be added.
The certification language of the ALTA Survey should include the names of the affected parties, including as appropriate the buyer, seller, title company, and lender. The surveyor must work in close association with the title insurance company, as the surveyor and the title company are relying on each other's work to show the matters affecting the ownership of the land and improvements in a comprehensive manner.
An ALTA land survey has especially stringent requirements as developed by a joint effort of the American Land Title Association and the American Congress on Surveying and Mapping. The ALTA standards are a nationwide uniform set of standards. Sometimes referred to as the "Cadillac of surveys". The survey is specifically designed to satisfy the needs of lenders, corporations and title companies when dealing with valuable commercial properties.
Topographic/ Existing Conditions/ Design Surveys
Surveying helps determine accurately the terrestrial or three-dimensional space position of points and the distances and angles between them usingleveling instruments such as theodolites, dumpy levels and clinometers.
Work on one of the first topographic maps was begun in France by Giovanni Domenico Cassini, the great Italian astronomer, who started his life in Italy.
Even though remote sensing has greatly sped up the process of gathering information, and has allowed greater accuracy control over long distances, the direct survey still provides the basic control points and framework for all topographic work, whether manual or GIS-based.
In areas where there has been an extensive direct survey and mapping program (most of Europe and the Continental US, for example), the compiled data forms the basis of basic digital elevation datasets such as USGS DEM data. This data must often be "cleaned" to eliminate discrepancies between surveys, but it still forms a valuable set of information for large-scale analysis.
The original American topographic surveys (or the British "Ordnance" surveys) involved not only recording of relief, but identification of landmark features and vegetative land cover.
An existing conditions survey is used to aid the engineer or architect in the design of a site plan for a proposed development. It contains all of the elements of the Topographic Survey (i.e. grades, contours, existing drainage) and additional information necessary for proper site design. A checklist describing what additional information is to be shown on the survey will be included under the scope of services for the survey. Typically, this additional information includes all structures and improvements to the property such as buildings, driveways, parking areas, concrete/asphalt areas, curb and gutter, water, sanitary and storm systems, invert elevations and pipe sizes, culverts, topsoil depths, etc. As with the Topographic Survey, approximate property lines may be shown for reference only and should not be construed as a Property Survey. The surveyor encourages the client to consider the importance of a Property Survey and a current Title Commitment and to either supply or order both when requesting an existing conditions survey
Staking Large Commercial and Retail Lots, Highway projects, and Subdivisions
A subdivision plat is required whenever more than 4 new parcels are created within a 5 year period. This is a state requirement and local ordinances may be more restrictive. A subdivision plat can consist of 2 lots to several hundred lots. The process usually starts with a consultation with the client to review the project and the clients design expectations. The surveyor will then review the feasibility of the project looking at issues such as rezoning, annexation, highway access, sewer availability, wetlands, floodplain, state and local ordinances, construction costs, etc. The concept plan phase is next which usually includes a Property Survey of the boundary of the subdivision, a Title Commitment and Existing Conditions Survey. The concept can also include preliminary lot and street layouts, address storm water management issues, utility connections and easements. If the concept meets with the approval of the client and local authorities we then move into the preliminary plat phase. At this point, the preliminary plat is sent to the state and local authorities for approval. Grading plans, utility plans, storm water management plans and developer’s agreements are finalized. Permits are also applied for. Once the preliminary plat is approved, the final plat is prepared and submitted for approval. The final plat contains exact lot dimensions, acreages, street names, easements, restrictions and monuments set. It also contains approval certificates to be signed by all agencies involved. Once all approvals and signatures are obtained, the final plat can be recorded at the Register of Deeds Office making the land divisions official.
The National Flood Insurance Program (NFIP) Elevation Certificate (EC) is an administrative tool of the NFIP which is to be used to provide elevation information necessary to ensure compliance with to community floodplain management ordinances, to determine the proper insurance premium rate, or support a request for a Letter of Map Amendment (LOMA).
Legal Description and Exhibits
A legal description is used to define an area of land. Legal descriptions can be used for many purposes including rezoning, annexations, land transfers and easements.
Mining surveying includes directing the digging of mine shafts and galleries and the calculation of volume of rock. It uses specialized techniques due to the restraints to survey geometry such as vertical shafts and narrow passages.

The purpose of an Underground Utility Survey is to produce a three dimensional drawing or site mark up of all underground utilities in a particular area. This cost effective methodology uses a combination of non-intrusive techniques to provide a comprehensive drawing of the sub-surface without the need for digging. Underground Utility Surveys detect all drainage, foul sewer, water main, oil and gas lines, power cables, fiber optic cables, telecom cables and ducting.
A survey to determine if a structure or object is changing shape or moving. The three-dimensional positions of specific points on an object are determined, a period of time is allowed to pass, these positions are then re-measured and calculated, and a comparison between the two sets of positions is made.
As-built survey: a survey carried out during or immediately after a construction project for record, completion evaluation and payment purposes. An as-built survey is also known as a 'works as executed survey' and documents the location of the recently constructed elements that are subject to completion evaluation. As built surveys are often presented in red or redline and overlaid over existing design plans for direct comparison with design information.
