Battle Born Ventures, LLC recently conducted a property corner survey of Lots #11 & #12 of the Donner Lake Tract at Donner Lake near Truckee, California. During the survey, Battle Born Ventures, LLC searched for and located several of the original property corners associated with the subject parcels that had been hidden by vegetation or covered by soil. For lost or destroyed corners, wooden hubs and mag nails were set representing the record positions of these corners. The owners of the property were able to determine whether or not the neighbors were encroaching onto their property with improvements, fencing, and junk. The project required researching record documents and maps, office calculations, and field surveying activities.
