Current through Register Vol. 50, No. 6, June 20, 2024
A. Prior to the final determination or
				  delineation of individual property ownership lines or boundaries, a preliminary
				  parcel map shall be constructed on 2 mil, dimensionally stable, single-matte
				  transparent film material or the equivalent for each final property ownership
				  map in the parish. The preliminary parcel map shall consist of an overlay of
				  the aerial photography and geographic base map of the project area.
B. No points or lines shall be constructed on
				  the photography or geographic base map, other than the initialization of
				  registration marks on the four corners of the image area. These registration
				  marks will also be placed on the preliminary parcel map as well as the final
				  edited parcel map. During the preliminary parcel map compilation phase, the
				  following detail shall be plotted:
1. using
				  the rights-of-way maps, acquisition surveys, or alignment plans, all public
				  road, street and highway rights-of-way will be made to register and coincide
				  with the physical and cultural features on corresponding photogrammetric or
				  base map enlargements of the aerial photography and associated geographic base
				  map to the fullest extent possible. Indications of the location of section,
				  township and range lines, or corners shown on the rights-of-way plans will be
				  considered in verifying the apparent location of lines and corners shown on the
				  aerial photography and/or geographic base map, or plotting same when not
				  shown;
2. using the original
				  township plats, surveyor's field notes, and USGS topographic maps as a guide,
				  satisfactory efforts shall be implemented to verify or confirm the location of
				  section, township and range lines and corners. The section, township and range
				  lines, and proportionate division lines of sections, shall be made to register
				  with any associated physical and cultural features on the corresponding
				  photogrammetric or base map enlargements as often as possible;
3. using available plans or surveys, all
				  railroad, pipeline or utility line rights-of-way, servitudes or easements will
				  be established and made to register with the physical and cultural features on
				  their respective photogrammetric or base map enlargement as often as
				  possible;
4. all recorded surveys
				  and subdivision plats shall be plotted to the proper property ownership mapping
				  scale. All plotted acreages, overall parcel dimensions, original lot and block
				  numbers, and subdivision names will be shown. The recorded surveys and
				  subdivision plats will be made to register and coincide with the physical and
				  cultural planimetric features on their corresponding screened enlargements as
				  often as possible;
5. a Parish
				  Index Map shall be developed during the preliminary parcel map construction
				  phase, delineating and assigning a permanent map number to the various 1" =
				  400', 1" = 200', 1" = 100', and 1" = 50' scale property ownership mapping areas
				  of the parish. The index map shall be developed utilizing the parish highway
				  base map layer to depict all road networks and other major planimetric detail.
				  A separate index of the areas enlarged to 1" = 200', 1" = 100' and 1" = 50'
				  scales shall be developed in the same manner as the master Parish Index Map.
				  Each enlarged area shall be labeled according to the name of the city, town,
				  village or area it represents. Permanent map numbers shall be depicted on all
				  index maps within the map area itself.
