Section XXVII-1725 - Final Parcel Map Production

A. Plotting. All hard-copy parcel maps shall be mechanically ink drafted using automatic pen plotters. Final parcel map sheets shall be prepared on 4 mil, dimensionally stable, double-matte polyester film such as Mylar, Cronflex, or the equivalent.

B. Sheet Size. The sheet size of the final parcel maps shall be 36 inches wide by 28 inches high and shall have a neat image area 25 inches wide by 25 inches high as shown within §1731, Appendix A.

C. Terms and Abbreviations. A glossary of terms and abbreviations to be included on final parcel maps is included within accompanying §1733, Appendix B.

D. Digital Drafting Standards. To assure uniformity of feature elements, line weight, lettering, numbers, and symbology, the uniform digital drafting standards set forth within Chapter 19 shall apply to the production of all final parcel maps developed under these standards.

E. Digital Data. Digital parcel map data shall be provided on acceptable MS-DOS formatted computer transfer media in DXF file format. Each parcel mapping feature, as identified by a unique feature code, shall be on a separate component layer or assigned to the feature element levels indicated within Chapter 19 for viewing and plotting purposes. Map data shall be stored on an acceptable digital format at the mapping consultant's facility until the responsible contracting authority and/or other responsible participants or users select and install their respective land information systems. Final map data must be compatible with the land information system in use or to be selected by the responsible contracting authority and/or other responsible participants and users.

F. Parcel Numbers. Parcel identification numbers should be located at or near the parcel centroid wherever possible. All parcel numbers should be parallel to the bottom of the map. When drafting consecutive parcels, all numbers should be kept in line. Parcel identification numbers ascribed to individual parcels on final map plots may be annotated to contain only the four digit centroid number to conserve label space provided that accompanying map and block numbers are clearly delineated on each respective map sheet.

G. Original Lots. Original lot lines shall be represented by dotted lines. Original lot numbers should be centered near the rear of the lot. Should a property line prevent this, the lot number can be moved up or down. A guideline should be used to keep the lot numbers in line. The lot numbers should be drafted parallel to the lot line.

H. Churches, Schools, and Landmarks. All identifying public buildings and related landmarks should be shown by name, when known. No symbols should be used. Names of these buildings and landmarks should be plotted parallel to the bottom where possible.

I. Acreage. The acreage should be centered under the parcel identification number where required and should read parallel to the bottom of the map sheet. If a parcel has both a deed acreage and calculated acreage, the deed acreage should be shown on top with a small (d) following it. The calculated acreage should be centered under the deed acreage with a small (c) following it. Field surveyed acreage, if applicable, should be similarly centered with a small (s) following it.

J. Dimensions. On all parcels requiring dimensions, the dimensions should be located in the center of the length of the line. When both a deed dimension and a calculated dimension are necessary, the deed dimension should be shown first with a small (d) after it, followed by the calculated dimension with a small (c). On 1" = 400' and 1" = 200' scale maps, when the parcel has the same rear dimension as the front dimension, and each side dimension is the same, only the front dimension and one side dimension are necessary. On 1" = 100' and 1" = 50' scale maps, when consecutive lots of the same size are being dimensioned, all front dimensions should be shown along with the first and last side dimensions.

K. Block Numbers. Map block numbers should be located near the center of each block. Each block number should be drafted to read parallel with the bottom of the map.

L. Subdivision Boundary Ticks. Subdivision ticks are used to show the boundary of each subdivision on the map. Ticks should be placed at all major corners of each subdivision on the map and numbered. The number is then placed in the appropriate space in the subdivision index on the border of the map sheet.

M. Land Hooks. When a land hook can be shown perpendicular to the line it crosses, it should be so plotted. Each side should be approximately the same length. The angle of the hook should be approximately 30 degrees and should point counterclockwise. Dashed land hooks will be used across division lines to denote separate parcels, but same ownership. Solid land hooks are used to denote same ownership, same parcel across roads, bayous, creeks, and so on.

N. "See Notes." "See notes" are used to show that a portion of the map is being mapped at another scale. On 1" = 400' maps, reference to 1" = 50', 1" = 100', and 1" = 200' maps should be shown. The scale and the map number should also be shown.

O. Conflicts. When there is a conflict of ownership, the conflicting property lines should be dashed instead of solid, and the word "conflict" should be written within the property in question.

P. Subdivision Names. All subdivision names, along with the plat book and page number, should be shown along with a numerical listing in the subdivision index on the map border. The corresponding numbers should be placed inside the subdivision boundary ticks on that portion of the map that it applies to.
