Louisiana Administrative Code › Title 43 - NATURAL RESOURCES › Part XXVII - State Lands › Subpart 1 - Land Information Mapping and Map Records System › Chapter 17 - Parcel Mapping › Section XXVII-1725 - Final Parcel Map Production

Current through Register Vol. 50, No. 6, June 20, 2024
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.
