The first step in finding your property lines is to determine the dimensions of your lot. You may be able to obtain this information from your deed or a plat map obtainable from the City Engineering Department or Brown County Recorder. If you are able to obtain a combination of this information, you can measure from the roadway curbs to find the property line. Use caution when using this method as this is assumed information that the roadway was constructed exactly centered within the platted City right-of-way.
The next step is to locate the survey pins, if they exist. Often these are located at the corners of your lot and at the beginning of a curve if the property line curves. Ask your neighbors if they have recently located the survey pins for their properties. This could save you the trouble of having to find them yourself. If no one knows where the pins are, you may wish to use a shovel to probe the area of the ground where they are assumed to be located. They can be a foot or more below grade. If that proves fruitless, you may need to use a metal detector or magnetic locator to help find them.
Many lots in New Ulm were surveyed many years ago and survey pins may have been removed. If this is the case, property lines may be located by measuring from the opposite pins on neighboring properties if you are allowed to locate them or other pins on the block where the locations are known. Once you locate a survey pin, do not disturb its location. Any person who willfully removes, destroys, or defaces a monument lawfully erected is guilty of a misdemeanor.
