Your house and my house and every legally built structure in the United States is recorded in one of two national databases. These databases are available to anyone to see and refer to. The reason we have these databases is to establish the exact location, positional orientation (compass heading), and elevation of every structure. This is important for the development of future construction sites (like you are going to build) so that integrated and non-conflicting buildings can be constructed in relationship to the structures and topography in surrounding areas.
This has a lot to do with building usages, square footages, flood zones, fire districts, drainage, utility right of ways, and things like that.
So, trying to keep it simple, you are required to tell your building department what you intend to build, where it is going to sit, and how high it is in relationship to something around you. They, in turn see that your new structure gets included in the latest update of the databases.
Wouldn’t it be a bummer if you built a house, and they soon came along with a new highway (or worse, a planned reservoir) that wiped your new house right off the face of the earth? This could happen if the government doesn’t have all this good information about your proposed project.
What you need to do is employ the services of a construction firm who will pull database records, do necessary surveys, and submit all pertinent paperwork to the proper government agencies concerning your proposed project.
All this needs to be done to stay legal, and before you worry about laying out anything. And when you do all this, your plans will magically have benchmarks and trig locaters printed right on them for your use in getting your new structure in the right place.
