The City of Knoxville has established a 3D network of survey control points throughout the city. The Department of Engineering maintains the network and publishes information for public use. This information is available via an interactive KGIS website. The City's network is based on the Tennessee Coordinate System of 1983. Horizontal coordinates for all points in the network (effective and destroyed) have been adjusted to conform to the National Spatial Reference System of 2007. The resulting information was published December 1, 2009. The interactive survey points website is maintained by KGIS and the City Engineering Department together, and allows the internet user to locate the nearest survey control points, print survey control data, print maps, compute bearings and distances, etc. Your computer screen resolution should be at least 800 x 600 in order for survey points website to display correctly.

Your cooperation is requested in maintaining the survey control network. Please prevent any damage or destruction to the survey control monuments, particularly during construction or paving work. Contact the Civil Engineering Division at 865-215-6100 (Don Jenkins or Richard Skaggs) to report disturbed or missing survey control points, or with any possible data discrepancies.

The Minimum Subdivision Regulations (MSR) for Knoxville and Knox County requires that surveys must be tied and rotated to the City's survey control system. Contact the Stormwater Engineering Division at 865-215-2148 (Molly Hyatt or Ben Davidson) for questions about survey control requirements and survey plat issues. Many topics can be answered by downloading either the Plat Review Checklist or Policy 17 from the Land Development Manual or the Letter To Area Surveyors.

A general reminder:

KGIS Maps is an interactive mapping KGIS website for general use that displays property ownership, addresses, buildings, streets, land use zoning, wards, voting precincts, school zones, CLT map numbers, parcel IDs, recorded deed references, city limits, political boundaries, etc.
