Visual Character. Visual character is an
impartial description of the landscape in terms
of dominance, scale, diversity, and continuity.
Visual character-defining environments and
features include landforms, vegetation, land
uses, transportation facilities, overhead utilities,
open spaces, water bodies, designated
viewpoints, and views to the visual
environment.
Visual Encroachment. The imposition of an
object, or objects, on a view such that the view is
disrupted, obstructed, or otherwise modified
from its original state.
Visual Quality. Visual quality is an assessment
of the visual character and is categorized as low,
medium, or high, as follows:
•    Low Visual Quality. Areas that have low
     visual quality may have features that seem
     visually out of place, lack visual coherence,
     do not have compositional harmony, and
     contain eyesores.

•    Medium Visual Quality. These areas can be
     generally pleasant appearing, but may lack
     distinctiveness, memorability, drama, and
     compositional harmony, or may simply be
     very common and ordinary landscapes.

•    High Visual Quality. These areas may be
     memorable, distinctive, unique (in a positive
     way), intact natural or park-like areas or
     urban areas with strong and consistent
     architectural and urban design features.

Volume to Capacity (v/c) Ratio. The ratio of
demand flow rate to capacity for a highway or
arterial facility; a v/c ratio below 1.0 means that
traffic volumes are below the capacity of the
roadway, when identified as greater than 1.0,
the traffic volume has theoretically exceeded the
carrying capacity of the roadway.
Washington State Department of Ecology
303(d) List. The federal Clean Water Act (CWA),
adopted in 1972, requires states to restore their
waters to be “fishable and swimmable.” The
CWA established a process to identify and clean
up polluted waters. Every 2 years, all states are
required to prepare a list of water bodies that do
not meet water quality standards. This list is
called the 303(d) list because the process is
described in Section 303(d) of the CWA.
