City of Knoxville Survey Control System (SCS) 

The City of Knoxville maintains the Survey Control System (SCS), a 3D network of survey control points that surveyors and engineers use to reference projects horizontally and vertically within the city.  The Civil Engineering Division and KGIS partner to maintain an interactive website that allows users to access the City of Knoxville Survey Control System.  Plat requirements relative to the Knoxville-Knox County Planning Subdivision Regulations and the use of the City of Knoxville’s Survey Control System provided by the Engineering Department's Development Services Division can be found by clicking here.

To maintain the accuracy and reliability of the Survey Control System, we ask for your cooperation with the following:

~ Do not disturb or remove survey control points - These points are vital to maintaining the accuracy of the Survey Control Network.
~ Notify the Engineering Department or 311 if a survey control point is damaged or destroyed.  Timely notification helps us update records and preserve the integrity of the network.
~ Coordinate with the City prior to any work that may impact survey control points.  Early coordination helps avoid conflicts and ensures the continued reliability and availability of the network.
