- Survey Control
The County Surveyor obtains survey control for use by the GIS Department in mapping parcels, as well as for other public purposes. These data are available for download from our Open Data site or as an Excel file. Data may also be viewed on the Survey Control App.
Geographic Information System – Survey Control Data Sheet Submission
According to the County Land Use Code, Section 4-504, surveyors submitting plats are required to submit Survey Control Data Sheets as follows.
4.504 A. The land surveyor who prepares the final plat shall provide accurate Latitude and Longitude values for at least two data points on the external boundary of the final plat. These data points shall be submitted to the County Surveyor by e-mail by completing a Geographic Information System – Survey Control Data Sheet, which is available on the County Surveyor website. If the land surveyor who prepares the final plat does not have GPS surveying equipment and is not able to determine accurate Latitude and Longitude values, or the project area is unsuitable for use of GPS equipment, a waiver of this requirement can be obtained from the County Surveyor.
4-504 B. An electronic drawing file of the final plat, in a format and version acceptable to the County GIS Department, shall be submitted by e-mail to the County GIS Department. If the land surveyor who prepares the final plat does not have drafting software capable of producing an acceptable electronic drawing file, a waiver of this requirement can be obtained from the Planning Director or County Surveyor.
