Adjacent scenery
greatly enhances visual
quality.
5
Adjacent scenery
moderately enhances
overall visual quality.
3
Adjacent scenery has
little or no inuence on
overall visual quality.
0
Scarcity
One of a kind; or
unusually memorable,
or very rare within
region. Consistent
chance for exceptional
or wildower viewing,
etc. **
5+
Distinctive, though
somewhat similar to
others within the

setting, but fairly
common within the
region.

Cultural
Modications
Modications add
favorably to visual
variety while
promoting visual
harmony.
2
Modications add little
or no visual variety to
the area, and introduce
no discordant elements.
0
Modications add
variety but are very
discordant and promote
strong disharmony.

Purpose: To rate the visual quality of the sce-
nic resource on all BLM managed lands.
How to Identify Scenic Value: Refer to
8431-1 illustrations 3, 4, 5, and 6 for
guidelines on descriptive terminology for
form, line, color and texture and illustrations
7 and 8 for additional terms to describe
landscape features and spatial orientation.
How to Determine Minimum Suitability: All
BLM lands are rated for scenic values. Also
rate adjacent or intermingling non-BLM lands
within the planning unit.
When to Evaluate Scenic Quality: Rate for
scenery under the most critical conditions
(i.e., the highest user period or season of use,
sidelight, proper atmospheric conditions, etc.).
How to Delineate Rating Areas: Consider
the following factors when delineating rating
areas.
1. Like physiographic characteristics (i.e.,
landform, vegetation, etc.).
2. Similar visual patterns, texture, color,
variety, etc.
3. Areas which have a similar impact from
cultural modications (i.e., roads, histori-
cal and other structures, mining opera-
tions, or other surface disturbances).
Explanation of Criteria:
(See H8410-1, Illustration 1.)
NOTE ABOUT SCORING: Values for each
rating criteria are maximum and minimum
scores only. Scores may be assigned at 0.5
increments within the ranges given.
NOTE ABOUT TOTAL SCORE: When the
Key Factor Score Total equals 11.5 (between
B and C) or 18.5 (between A and B), then
reassess the factor ratings and either adjust the
rating 0.5 upward or downward placing the
unit into the most appropriate scenic quality
class.

CLASSIFICATION
A = 19 or more
B = 12-18
C = 11 or less
** A rating of greater than 5 can be given but must be supported by written justication.
