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-1709 - Map Sheet Requirements

Current through Register Vol. 50, No. 6, June 20, 2024
A. Map
				  Size. The outside edge dimensions of all hard-copy parcel overlay maps shall be
				  28 inches high by 36 inches long. The neat image area shall be 25 inches high
				  by 25 inches long. All parcel maps will be the same size and layout as the
				  Geographic Base Map Sheets, and shall always bear the same sheet numbers as
				  defined in Chapter 15.
B. Map
				  Scale. Final hard copy parcel maps shall be at a scale of 1" = 50', 1" = 100',
				  1" = 200', or 1" = 400' based upon respective area classifications as set forth
				  within Chapter 3.
C. Legend and
				  Margin Information. A legend of principal map symbols, north arrow, disclaimer
				  note, map index, bar scale, map number, and chart for record of revisions will
				  appear in the right hand margin of the map sheet. All marginal information will
				  be placed on the parcel map in such a fashion so that when this map is
				  overprinted or layered with its respective base map, all marginal information
				  from both maps will be clearly legible. The map number on the parcel map will
				  be, in all cases, the same as the map number for its respective, or matching,
				  base map.
D. Block Lines and
				  Numbers. On all scales of parcel maps, the neat image area will be subdivided
				  into "map blocks" for the purpose of building the Parcel Identification Number
				  (PIN). The map block will be a 1,000 foot square whose boundaries will conform
				  to the even 1000-foot divisions of the Louisiana State Plane Coordinate System
				  and will be delineated by fine block/grid lines running north-south and
				  east-west across the entire neat image area. A two-digit block number, derived
				  from the PIN system, will be printed in the center of each block using "hollow"
				  numbers. See accompanying §1731, Appendix A, for parcel map layout and
				  block number designations for each respective map scale.
E. Grid Ticks. On parcel maps at a scale of
				  1" = 50' and 1" = 100', the 25" by 25" neat image area will be further
				  sub-divided with block lines or "grid ticks" (1/2" crosses) placed where
				  theoretical north-south and east-west lines drawn every 5 inches on the image
				  area would run or intersect. Grid ticks will be shown on those points where
				  intersecting block lines do not appear. Grid ticks will appear as block lines
				  on the finished (positive) maps.
F.
				  Adjoining Parishes. Any parish contemplating the development of parcel maps
				  under these standards shall determine if any of its adjoining parishes have
				  already been mapped in conformance with these state standards. If so, the
				  responsible contracting authority for the parish shall obtain digital records
				  of all such existing parcel map sheets adjoining its boundaries for use as
				  source materials. The adjoining parish's map data and the map data at the
				  contracting parish's borders shall be matched to the maximum extent possible,
				  but in no case less than the edge matching accuracy requirements set forth
				  within Chapter 13.
