A. The areas of parcels shall be obtained from the assessment records, the recorded map references, or the deed of record when used in the preparation of new ownership maps. All parcel areas shall be verified by coordinate geometry (COGO) or electronic digitization, as applicable, and rounded to the nearest 1/100 of an acre with the symbol (d) shown beside the recorded deed acreage. Example: 12.26ac(d).

B. In the absence of recorded deed areas, or in the event the recorded deed areas are ambiguous, unclear or in error, the parcel shall be computed to the nearest 1/100 of an acre with the symbol (c) shown beside the computed acreage. Example: 12.26(c).

C. Areas determined from the latest recorded field survey of any property parcel shall be rounded to the nearest 1/100 of an acre with the symbol (s) shown beside the field surveyed acreage. Example: 12.26(s).

D. The numeric values of all recorded deed acreages, computed acreages and available recorded field survey acreages for each property parcel shall be included on the parcel index record for subsequent incorporation into the relational data base. The inclusion of recorded deed, computed, and/or field survey acreages on the final parcel map manuscript is optional and subject to the discretion of the parish.
