The purpose of this chapter is to establish standards that will
assure proper sight distances at intersections to reduce the hazard
from vehicular turning movements.
(Ord. 17-22 §2)
A.
Applicability. The provisions of this chapter apply to
all development, including the construction of new structures, the
remodeling of existing structures, and to a change of use that increases
the on-site parking or loading requirements or changes the access
requirements.
B.
When site development review is not required. Where the provisions of Chapter 18.780, Site Development Review, do not apply, the approval authority will approve, approve with conditions, or deny a plan submitted under the provisions of this chapter through a Type I procedure, as provided in Section 18.710.050, using the standards in this chapter.
(Ord. 17-22 §2; Ord. 18-23 §2)
A.
At corners. Except within the MU-CBD zone, a vision clearance
area must be maintained on the corners of all property adjacent to
the intersection of two streets, a street and a railroad, or a driveway
providing access to a public or private street.
B.
Obstructions prohibited. A clear vision area must be
maintained free of vehicles, hedges, plantings, fences, wall structures,
and temporary or permanent obstructions (except for an occasional
utility pole or tree), exceeding 3 feet in height, measured from the
top of the curb, or where no curb exists, from the street center line
grade. Trees exceeding 3 feet in height may be located in this area,
provided all branches below 8 feet are removed.
C.
Additional topographical constraints. Where the crest
of a hill or vertical curve conditions contribute to the obstruction
of clear vision areas at a street or driveway intersection, hedges,
plantings, fences, walls, wall structures, and temporary or permanent
obstructions must be further reduced in height or eliminated to comply
with the intent of the required clear vision area.
(Ord. 17-22 §2; Ord. 18-23 §2)
A.
Arterial streets. The vision clearance area is not less
than 35 feet on each side of the intersection.
B.
Non-arterial streets.
1.
Non-arterial streets 24 feet or more in width. At all intersections
of 2 non-arterial streets, a non-arterial street and a driveway, and
a non-arterial street or driveway and railroad where at least 1 of
the streets or driveways is 24 feet or more in width, the vision clearance
area is a triangle formed by the right-of-way or property lines along
such lots and a straight line joining the right-of-way or property
line at points that are 30 feet distance from the intersection of
the right-of-way line and measured along such lines. See Figure 18.930.1:

2.
Non-arterial streets less than 24 feet in width. At all intersections
of two non-arterial streets, a non-arterial street and a driveway,
and a non-arterial street or driveway and railroad where both streets
or driveways are less than 24 feet in width, the vision clearance
area is a triangle whose base extends 30 feet along the street right-of-way
line in both directions from the centerline of the accessway at the
front setback line of small form residential, and 30 feet back from
the property line on all other types of uses.
