What is this service?
This service provides access to the precinct mapping information maintained by the Clerk-Recorder office for election purposes. Geographical information systems (GIS) technology has been used to maintain precinct boundaries and map printing. Use of data maintained by various county departments and agencies (Public Works, Assessor, Planning & Building, Cities, LAFCO, the Citizens Redistricting Commission, and the Census Bureau) and GIS technology when drawing precinct boundary lines results in more accurate and up-to-date maps.
The County of San Luis Obispo does not assume liability for any damages caused by any errors or omissions in the data of the precinct maps. The County of San Luis Obispo makes no warranty of any kind, express or implied, that these data are accurate and reliable, nor does the fact of distribution constitute such a warranty. Independent verification of all data contained on these maps should be obtained by any user thereof. Users assume responsibility to determine the appropriate use of these data.
