We would like to applaud and spread the word about Alameda County's increased offerings for geospatial data. For anyone who looked before, you remember the single layer of parcel outlines. The new offerings include layers from supervisor districts to sanitation districts. This is a small step towards open data and we look forward to seeing the county continue along this course.

The layers are static and can be downloaded as zipped shapefiles.
