This polygon shapefile depicts boundaries of parcels over which the County of Solano, California held authority in 2012. A Parcel is a piece of real property under a defined ownership, or it can be a lot in a subdivision. County governments administer and legislate through the creation of and maintenance of land records that are associated with a parcel of land. Thus the Parcel is often the vital administrative unit of local government. Parcel maps must meet the requirements of the General Plan and all applicable laws and ordinances. Parcel maps are alternately called tax maps, plat maps, plot maps and assessor maps. This dataset includes Active Parcel Numbers (APNs).
