Threshold: The travel route rating threshold tracks long-term, cumulative
changes to views seen from major roadways in urban, transitional,
and natural landscapes in the region and to the views seen
from Lake Tahoe looking toward the shore.
Indicator(s):To secure threshold attainment, all travel routes with
a 1982 score of 15.5 (roadway) or 7.5 (shoreline) or greater
must maintain their scores, and all travel routes with a 1982
score of 15 (roadway) or 7 (shoreline) or less must improve
their scores until the threshold score is reached.
SR-2, Scenic Quality Rating
Threshold: The scenic quality rating threshold protects
specific views of scenic features of Tahoe's natural landscape
that can be seen from major roadways and from the lake.
Indicator(s): To secure threshold attainment,
all 1982 scenic quality scores must be
maintained.
SR-3, Public Recreation Areas and Bike
Trails

from public recreation areas and certain bicycle trails.
Indicator(s): To secure threshold attainment, all 1993 scenic quality
scores must be maintained.

is a policy statement that applies to the built
environment. Design standards and guidelines
found in the Code of Ordinances,
the Scenic Quality Improvement Program, and in
the adopted Community Plans
provide specific implementation direction.

guidelines must be widely implemented to improve travel route
ratings and produce built environments compatible with the
