Also known as a “topo survey”, these surveys map the vertical and horizontal configuration and location of natural and artificial “man-made” items. Maps typically include contours and pertinent features on a piece of property.
Boundary & Easement Surveys
Boundary surveys are sometimes known as “mortgage surveys”, “lot surveys” or “closing surveys”. They are used to locate property corners and lines. Easement surveys can establish or locate existing or proposed easements for access or utilities.
Construction surveys can be used to document construction progress or verify volumes of excavation. Construction stakeouts are used to place points converted from design drawings on the ground, to ensure buildings and infrastructure are constructed in the right place and at the right elevation.
These can also be called “elevation flood surveys”. Insurers will require these to obtain flood or property insurance. They show the risk of flood for a specific property based on FEMA mapping.
ALTA / NSPS Land Title Surveys
ALTA surveys are similar to a Boundary survey, but provide more detail in regards to the property. They can include information such as easements, encroachments, or other potential issues. These are often requested for large developments or investments.
Subdivision & Recombination Surveys
Subdivisions and re-combinations divide land into multiple tracts and reconfigure existing lot lines. These could range from a simple inheritance division to a large single family neighborhood.
Geomorphological Surveys map stream, creek, and riverine systems in preparation for stream restorations. This survey can be completed on design reference reaches or channels to be restored and aid in riparian buffer location.
As-built surveys document recently completed conditions immediately after construction. These surveys can quantify any differences between design and construction. Municipalities sometimes require these surveys for verification that installation meets their standards.
USACE Jurisdictional Determination Mapping
These surveys required by the United States Army Corps of Engineers map agreed upon extents of jurisdictional features within a delineated area. Typically this maps include boundaries of wetlands, streams or creeks, and riparian buffers. JD Maps are usually only required for developments adversely impacting these environmental features.
