The County Surveyor's Office maintains official county maps and perpetually maintains original government survey section corners, the basis for all property boundaries. In cooperation with the County Drainage Board, this office manages the County's 600 miles of legal drain (stormwater drainage) system, and also reviews subdivision proposals in unincorporated areas of the county for proper compliance with County ordinances. The County Surveyor coordinates the development of Lake County's computerized mapping, the Geographic Information System (GIS), along with other record and mapping responsibilities.
