Indiana statutory law requires the County Surveyor to locate and perpetuate the original section corners in the county, and to recheck at least five percent of the corners that have known ties each year. Marion County currently has ties to more than 2350 corners which are the basis for property boundaries in the county.
The Office, by statutory law, also maintains a Legal Survey Record Book, and a Section Corner Record Book, and maintains and publishes a county road and section map, which also shows points of interest within Marion County.
Since 1991 the Marion County Surveyor has established State Plane Coordinates on section corners and aerial photographic control points with Global Positioning Systems. GPS yields valuable information to surveyors, engineers, city planners, utility companies and private enterprises. State Plane Coordinates help produce more accurate and efficient land surveys for the residents and businesses of Marion County.
The County Surveyor's Office also provides vertical control information to various City-County Offices, private contractors, utilities, and the general public.
All City-County Offices freely use our expertise to interpret, advise, and write legal descriptions. We perform surveying services for the City, County, and Township Offices when requested. This includes right of way surveys, drainage surveys, building locations, locations of improvements with regard to zoning violations, property surveys of City, County, and Township owned property. Our surveys are used to prepare plans for ditches, drains and streams. We also prepare forensic maps for the Marion County Prosecutor when requested. The Eagle Creek Dam is monitored annually by the Marion County Surveyor's Office for horizontal and vertical movement.
