Assessor's Maps - Cadastral Drafting
The Assessor's responsibilities include locating, inventorying, and appraising all property within the county. To achieve this, the Assessor's Office needs a complete set of maps which shows each parcel of property within the county that is separately owned and used.
The function of the cadastral drafting section is to maintain the accuracy of the Assessor's Map books on a continuous basis. Parcel splits, parcel combinations, and lot line adjustments all have mapping implications. The assessment cycle involves parcel mapping activities brought about by subdividing or other lot splitting or lot combining actions. The cadastral drafting section is responsible for preparing all map changes related to such activity. As the number of parcels increases through division, map pages are drawn and redrawn, until entire new map books must be created.
The extent of properties within each county is such that the assessor's office cannot be efficiently systemized and procedures simplified without a basic system of maps. The basic system of maps must be a coordinated system prepared in accordance with certain standards for the entire county. The Assessor's Office could not perform its functions efficiently without a coordinated map system because the legal assessment of real property presumes a legal description of the real estate. Faced with the problems of determining good legal descriptions from poorly written deeds, of describing the remainder of parcel(s) when a portion is deeded out, and abbreviating long metes and bounds descriptions, the Assessor's Office relies on the Assessor's Maps for fulfillment of the office's responsibilities.
In addition to the mapping, duties, the cadastral drafting section is also the Assessor's Office representative to the County's Development Review Committee. The departments of Engineering, Planning, Environmental Health, Roads, Assessor, and Fire comprise this body whose purpose it is to evaluate large-scale proposed projects.

The Assessor's Office maintains its own Assessor parcel maps for all property located within Madera County. These maps are the basis for the assessment of real property, and are continuously being updated to reflect parcel additions, deletions and changes to existing parcel boundaries. These maps are available for review and purchase at the Assessor's Office public counter.
