identify accomplishments to date, and identify the workload still be accomplished.
Classify National Forest System property lines to assist in setting surveying and
resource management priorities and identifying the magnitude and potential
severity of property boundary line problems.
2. Use the following to accomplish the inventory and classification.
Property Lines: These are the property lines between United States
Government land administered by the Forest Service and adjoining claim property
lines, and so forth. It does not include administrative lines which have National

Property Corners: These are land survey corners such as section corners, 1/4section corners, homestead entry corners, mineral survey corners, United States
survey corners, acquisition survey corners, etc., the define the property lines
between land administered by the Forest Service and adjoining land owned or
administered by others. It also includes subdivision-of-section corner points of
Forest Service property lines, whether or not the actual corner monuments and
accessories have yet been established on these points. It does not include corners
which are needed to control Forest Service property include corners which are
needed to control Forest Service property lines, but which are not actually on Forest
Service property lines.
Property Controlling Corners: These are land survey corners that are needed
to control Forest Service property lines, abut which are not actually on the Forest
Service property line itself. It includes those corners needed to reestablish lost
property corners and to establish new property corners such as in subdivision-ofsection survey.
Inventory land corners according to the following two classes and four status
categories:
a. Land Corner Classes:
(1) Property Corners.
(2) Controlling Corners.
b. Status Categories:
(1) Official Corner Found.
(2) Corner or evidence found, believed acceptable.
(3) Corner searched for and not found.
(4) Corner needed, but not yet searched for.
Inventory the miles of property boundary line according to the following two
categories and five risk classes:
a. Property Boundary Line Categories:
(1) Miles of line marked and posted to standard.
(2) Miles of line not posted and marked to standard.
b. Risk Classes:
(1) High Risk (excluding Mineralized Areas Classified for Disposal)
meeting at least one of the following:
(a) Line adjacent to high value improvements (permanent structures with value in excess of $1,000,
excluding fences) known or suspected to be located on National Forest System land.

(b) Line adjacent to area of suspected trespass of National Forest resources, i.e., timber, mineral
materials, etc.
(c) Line adjacent to low value improvements (permanent and non-permanent structures, fixtures,
etc., including fences) known or suspected to be located on National Forest System land.
(d) Line adjacent to land with high development potential (oil, gas, minerals, timber, real estate).
(e) Line adjacent to private land within congressionally designated areas (wilderness, wild, and
scenic, etc.).
(2) Medium Risk (Excluding Mineralized Areas Classified for Disposal):
(a) Line adjacent to land with minimal development potential (oil, gas, minerals, timber, real estate).
This includes lands zoned as agricultural or open space, and lands in flood plains or containing
unstable soils.
(3) Low Risk (Excluding Mineralized Fractions Classified for Disposal
meeting at least one of the following:
(a) Line adjacent to State or local government owned land within congressionally designated areas
(wilderness, wild, scenic, etc.).
(b) Line adjacent to all remaining State or local government owned land.
(c) Line adjacent to lands administered by other Federal agencies.
(4) Administrative Boundaries:
(a) Land located totally within Forest Service ownership and is not property boundary.
(5) Mineralized Areas Classified for Disposal:
(a) Line adjacent to patented mineral surveys with known or suspected
trespass.
(b) Line adjacent to patented mineral surveys with no known or suspected trespass.
Unsurveyed mileage accuracy should be comparable to that obtained from a
Primary Base Series (7-1/2 minute quadrangle). The Land Line Location Atlas
should be checked against the Land Ownership Status Atlas to be sure all land
adjustment activities (acquisition and disposal) completed to date are shown
through the previous fiscal year.
Document the information to the extent that the information can be accurately
reconstructed.
3. Field-going personnel shall aid in the protection and maintenance of corner
documents and corner evidence encountered during field work. Do not perform
destructive investigations. Mark with flagging and report corner discoveries to the
Forest land surveyor, using Form 7100-52 (Corner Record) or a short written
description.
4. Cadastral Engineering Report, Form 7100-5 shall be completed each fiscal
year and maintained as a part of the Forest records.
