is normally on a much larger parcel, typically larger than one acre. This type involves locating the property corners as marked by an iron pipe, a rebar, or some other monument and preparing a survey drawing. Improvements on the parcel may or may not be located, depending on the proposed use of the survey. Boundary lines may or may not be marked, depending on the clients’ request. Easement lines, if any, will also be located.
Surveying measurements that are made prior to, or while a site is under construction, to control the horizontal position and vertical position (elevation).
A site plan is prepared, normally, in order to obtain approval to construct some type structure on a lot, like a house. This may involve field work, depending on the circumstances. The majority of site plans are completed in the office. After approval of the site plan, then some construction staking might take place.
A survey that locates natural and man-made features such as buildings, fences, improvements, easements, utilities, trees, streams.
This type is done in order to divide a parcel into smaller parcels. This might be as few as two lots or hundreds or lots.
A subdivision “plat” (drawing) is completed which is then approved by the county and/or city and then recorded in the local courthouse.
Performed to determine the elevation of a structure (house) and it’s relation to the floodplain.
This type can be similar to the Residential Lot or Boundary Survey above but it is done to a different standard, the ALTA Land Survey standard. ALTA is the American Land Title Association. An ALTA survey is very comprehensive (read costly) and is most often performed on commercial property or when a lender is out of state. This is a widely accepted national standard for surveying.

Percolation & Soils Testing
Conducting a percolation test and soil boring is not technically considered land surveying, but land surveyors are one of three professionals that are qualified to perform these tests. A “perc” test is done in order to determine if sewage effluent will soak (percolate) into the ground in an onsite septic system.
The soil boring helps the surveyor determine the depth to perform the perc test. The soil boring might indicate water or rock, a limitation to the placement of field lines. The perc rate will determine the length of field lines needed.
