Certified Survey Map (CSM)
Considered a minor subdivision, used to either divide land into two or more parcels, combine two or more parcels into one, or to alter lot lines between adjacent landowners. This will also show any type of encroachments that affect the property. The maximum lots allowed on a Certified Survey Map is 4 lots. This map requires County and Town/City approval. The County generally has a in-house review. Town and Cities usually have a public meeting that is required to be attended by the landowner or representative of the survey. There are also review fees that apply, which vary in each municipality.
Plat of Survey
Also referred to as property, lot line, or boundary surveys, this is used mainly to mark existing property lines, and show any type of encroachments that affect the property. This should be done anytime that property is purchased to know exactly what you are buying, and if there are any encroachments onto the property, or vice versa, so they can be properly addressed. This can also be used to create a parcel of land if local subdivision ordinances allow. This does not need Town/City or County approval.
American Land Title Association (ALTA)
Survey that is typically requested by the Lender, to insure title to land without exception as to many matters which might be discoverable from survey and inspection, and which are not evidenced by the public records. The Surveyor will document and certify to everything that is asked for by the client in Table A in the 2011 Minimum Standard Detail Requirements for ALTA/ACSM Land Title Surveys.
Letter of Map Amendment (LOMA)
Used to remove structures and/or land from the 100 Year Flood Plain as mapped by the Federal Emergency Management Agency (FEMA).
Used to obtain, or document whether Flood Insurance is needed. Also used by some local Zoning Departments for new construction, to document elevations in relation to the 100 Year Flood Plain.
Used to designate limited common and common elements for structures, living spaces, and land.
This is used in areas where there are many discrepancies and conflicting information from older deed and survey records. This will properly mark the intended lot line position of all parcels. A town or city has the power to order this map.
Used to create 4 or more lots under 1.5 acres in a successive 5 year period. This is considered a major subdivision compared to the Certified Survey Map process. An official Wetlands determination, Soil Borings and a Drainage Plan are a few of the things that need to be done. This must be approved by the Town/City, County and the State.
This is typically done in the early stages of construction planning, with the surveyor taking horizontal and vertical measurements on the property to create contour lines of the ground, and also locating all pertinent natural and man made features. This data is then given to a engineer and/or contractor so they are able to design the planned construction.
This is used when contractors are in need of the horizontal and/or vertical layout of homes, roads, subdivisions, sewers, bridges, etc, in relation to lot lines, right of way lines, existing features, and existing benchmarks as designated on construction plans.
