Scenic Restrictions
Section 530
Section 530.260 Scenic
Restrictions
a) Special restrictions on utility occupancy may be imposed where
visual quality is an important consideration; for example, scenic easements,
rest areas, public parks, overlooks, and recreation areas.
b) New underground or aerial installations may be permitted only
when they do not require extensive removal or alteration of trees or terrain
features visible to the highway user or impair the aesthetic quality of the
lands being traversed.
c) Aerial installations may be permitted only when:
1) other locations are not available or are unusually difficult
and costly, or are less desirable from the standpoint of aesthetic quality;
2) placement underground is not technically feasible or is
unreasonably costly; and
3) the proposed installation will be made at a location, and will
employ suitable design and materials, which give the greatest weight to the
aesthetic qualities of the area being traversed without adversely affecting
safety. Suitable designs include, but are not limited to, self-supporting armless,
single-pole construction with vertical configuration of conductors and cable.
