Closed, Illegal and Abandoned (CIA) Disposal Sites

Assessor's Parcel Number or Map

When conducting a phase I office investigation it is necessary to obtain a parcel number in order to obtain a title or deed for the property in question. The title or deed helps to establish the responsible party(ies) as well as the contact person(s) for that particular piece of property.

An assessors parcel number or map is typically obtained from a city or county assessor's office. The map provides information on the legally surveyed physical boundaries for a parcel or tract of land which contains a disposal site.

Please follow the links below to find either the county assessor's web page or contact information.
