Subdivision maps show the shape and dimensions of lots and where survey pins/ property markers were placed, designating property corners and establishing lot boundaries. Surveying pins are typically not exposed and are found several inches below the ground surface. To accurately determine property boundaries, where property markers don’t exist or can’t be easily located, a survey should be conducted by a licensed land surveyor. The surveyor will locate existing property corners or set new survey pins/property markers. The City does not locate property boundaries in the field.
