2. Bikeways or bicycle lanes are required on all urban Collectors and Arterials, including Special Area Collectors. A Six-foot wide, striped
and stenciled bike lane or other appropriate bicycle treatments shall be constructed along these facilities except where special con-
straints exist, as determined by the County Engineer. In those areas, five-foot wide bike lanes, 14-foot wide outside travel lanes or other
appropriate facilities may be used and transitioned back to the appropriate bicycle facility when the constraint ends. The Bicycle Facility
Design Toolkit should be referenced during the design of urban Collectors and Arterials. Outside of the UGB, refer to the Bicycle System
Map and the Rural Roadway Enhancement Study Corridors Map to determine which facilities are intended to have bikeways. Rural
bikeways may be a minimum of six-foot wide paved shoulders.
3. Minimum right-of-way and maximum paved widths identified here are, as a rule, the maximum that can be built on roadway seg-
ments without an amendment to the TSP. However, plan amendments will not be required when it is determined by the County Engineer
during the project development or development review processes that these maximums should be exceeded. The reasons to exceed the
maximums may include accommodation or topography or other project-level refinements associated with safety and/or wider bicycle and/
or pedestrian facilities; transit facilities ; on-street parking; project impact mitigation measures; and intersection, interchange or other
project features identified as necessary for safe, efficient operation of the planned transportation system. All intersections along Arteri-
als and Collectors shall be planned to include right-of-way necessary for turn lanes within 1,000 feet of intersections based on a 20year
analysis of intersection needs. Actual right-of-way requirements may be less than the maximums specified in the table based on roadway
characteristics and surrounding land uses, as determined by the County Engineer. On two and three lane urban Collectors, right-of-way
may by reduced to 60 feet and maximum paved width may be reduced to 36 feet through the land development or project development
processes. Such a determination can be made when there is a finding that a turn lane is reasonably unlikely to be needed based on antici-
pated future development and traffic analysis, and after consideration of other related transportation facilities including storm water quality
facilities. Acquiring adequate right-of-way is important to avoid unnecessary and costly future improvement impacts. In all circumstances,
Arterial, Collector and Neighborhood Route right-of-way shall be no less than the roadway width (curb to curb or back of shoulder to back
of shoulder) plus 24 feet. In rural areas, the maximum right-of-way for Collectors shall be 60-feet. Article VII of the CDC identifies land use
standards, public notice and involvement provisions and appeal opportunities that are provided in the land use permitting process.
4. On those roadways designated on the Pedestrian System Map as ’Pedestrian Parkway’, ‘Streetscape Overlay’, or located within
identified ‘Pedestrian Districts’, sidewalks widths and other design features such as planter areas and crosswalks should be determined
based on the Washington County Pedestrian Enhancements Design Guidelines and/or applicable standards in the Community Plans
and/or the CDC, as determined by the County Engineer. On those roadways designated on the Bicycle System Map as ‘Enhanced Major
Street Bikeway’, buffered bike lanes and other bicycle treatments shall be determined based on the Bicycle Facility Design Toolkit and/
or other applicable standards in the Community Plans and/or CDC, as determined by the County Engineer.
5. ‘Special Area’ streets (Collector, Neighborhood, Commercial or Local classifications) are shown on the ‘Special Area Street Overlay’
maps. Special Area Local Streets may also be designated in the appropriate Community Plans and/or by the CDC. Additional Special
Area Neighborhood Routes and Special Area Local Streets may be designated using the development review process. Special Area
ADOPTED TEXT right-of-way, a nine-foot minimum utility/sidewalk easement shall be dedicated on each side of the right-of-way. For Special Area Local
Street designs will be determined via the development review process. While Special Area Commercial Streets do not include striped
bicycle lanes, they shall include wide travel lanes of 14 feet to accommodate bicycle use. For Special Area Collectors, in addition to the
streets, in addition to the right-of-way, a ten-foot minimum utility/sidewalk easement shall be dedicated on each side of the right-of-
way. For Special Area Alleys, additional right-of-way may be required as part of development review. The right-of-way determination may
include special consideration of other related transportation and water quality facilities, such as (but not limited to): low impact water
quality treatment, parking, intersection bump outs, mid-block crossings and/or trail extensions.
6. Consult the Pedestrian System Map for the Streetscape Overlay definition and location.
7. Consult the Bicycle System Map for the Enhanced Major Street Bikeway definition and location.

Interim Functional Classification Designations
Some roadways in Washington County have an interim Functional Classification designation. These are
roadways where the designation is expected to change once planned elements of the system have been com-
pleted. These roadways/locations are described below.

Joss Avenue
NW Joss Avenue is designated as an Interim Collector on the Functional Classification Map. It is anticipated
that NW Joss Avenue ultimately will be reclassified to its expected function as a Neighborhood Route after
the construction of Shackelford Road to NW 185th Avenue. See the Bethany Community Plan (Chapter 2:
North Bethany Subarea Plan) for additional details.

Saltzman Road
The segment of NW Saltzman Road between NW Laidlaw Road and NW Bayonne Lane is anticipated to be
realigned west of its current alignment, to the intersection of NW Laidlaw Road at NW 130th Avenue. The
realigned segment of Saltzman Road is designated on the Functional Classification Map as a Proposed
Collector. Interim improvements to the existing alignment may be implemented to enhance the operation of
the facility until the realignment has been completed. After the realignment of Saltzman Road is in place, it
is anticipated that the current alignment of Saltzman will be reclassified consistent with its new function as
either a Neighborhood Route or a Local Street. The appropriate classification will be determined based upon
observed traffic operations and needs after the realignment is complete.
