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 County's 600 mile 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.
In light of the seriousness of the COVID-19 virus, the Lake County Surveyor’s Office will be closed to the public until further notice. Office staff will be available to assist by telephone, email, by mail, and if necessary, by appointment. The Surveyor’s Office is committed to serving residents of Lake County and keeping our staff and the public as safe as possible. Thank you for your cooperation.
