Sierra County Geographical Information System
The Sierra County Geographical Information System is here! You can view a map of the County and get Census
information and zoom in on Assessor's parcels to see data for parcel number, situs, land use and zoning.
You can search and create reports showing parcel acreage and assessed values. SHAPE files and data are available from the Sierra County Information Systems Department. For information about purchasing the data, please contact the Assessor's
Office at (530)289-3283 or email assessor@sierracounty.ws .
