According to the website and the projection file of the shapefiles, the data is referenced in a local system, State Plane Coordinate System projection Lambert Conformal Conic, Datum NAD83, revision 1997. This is a local system, meaning that if one would need to work with this data in conjunction with other datasets that are referenced, one would firstly have to geo-reference it, a process that is not trivial whatsoever, when considering vectors.
