Parcels for the City of San Leandro (CSL). Alameda County (ALCO) maintains several attributes: parcel number (APN), site address, lot size, assessor map, all monetary values, and primary and secondary tax rate areas; CSL has no control over those attributes. CSL maintains the geometry and these attributes: zoning, general plan land use, and the common area, condo and stacked flags. CSL also applies FEMA zones and Cal Fire fire hazard zones to parcels. Condos are not drawn realistically; instead, each condo outline is the outline of the entire complex; what looks like a single parcel is actually all condos in a complex stacked one on top of the other.
