ALTA/ACSM surveys are the most comprehensive type of land survey and, as such, tend to be the most expensive. These surveys have standardized guidelines and reports and are used in many kinds of real estate transactions to ensure consistent and accurate information is available for properties.
A land survey includes the layout of a single property, including precise measurements and to-scale drawings of boundary lines, land improvements, and sometimes other features, like topography and drainage information. A plat map includes the layouts and boundary lines of several adjacent plots and basic structure measurements. Surveys are normally more valuable for homeowners and buyers, and plat maps are for governmental use.
Land surveys don’t technically expire. They do serve as a point of reference and a snapshot of your property, though, so as soon as you make changes to your property (and even if your neighbor makes certain changes to theirs), your existing land survey becomes inaccurate, and a new one must be done. Even if you don’t make any changes to your property, many states only guarantee the accuracy of a land survey for five to ten years.
This is fairly rare, but sometimes the local government or a group like a historical society will label a tree as a landmark, or historical item. These designations almost always come with a small, on-site plaque for identification, but you should also be able to look up protected trees in your area on a city website or similar list. If the tree in question is a landmark, call your local government and ask how to proceed before making any plans.
Land survey reports have a boatload of information relevant to several scenarios. Here are the types of information contained with a survey, though it depends on your chosen type of land survey. Exact boundaries and dimensions of a given property General topography, including both natural and artificial landmarks Location of utility fixtures, like water mains Confirmation of any easements or encroachments on a piece of property Assessment of land elevation to buy flood insurance Updated information to add to a pre-existing property map
