consideration of other classifications in this TSP and in reference to the Community Plans, Community Develop-
ment Code as well as adopted city plans and codes. Pedestrian Parkways in the Washington County TSP are
equivalent to on-street Pedestrian Parkways shown in the Metro Regional Transportation Plan. 14

Streetscape Overlay
A Streetscape Overlay is a segment of urban roadway in which enhanced pedestrian features, expanded pe-
destrian facility dimensions and place-making amenities are encouraged in order to facilitate a comfortable
and attractive walking environment, and to leverage community and economic development. Streetscape
Overlays include all Regional Boulevards and Community Boulevards shown on the Regional Design Clas-
sifications map in Metro’s 2014 Regional Transportation Plan (RTP) within Washington County. These
15
segments are typically located within Metro 2040 Growth Concept Regional Centers, Town Centers, Station
Communities and Main Streets. Several additional Streetscape Overlay segments are shown in the urban
unincorporated area based on Washington County community planning projects such as the Aloha-Reedville
Study and Livable Community Plan and the North Bethany Subarea Plan.

On roadways with Streetscape Overlays, appropriate features and dimensions will vary by context and shall
be determined through the project development and/or land development review process. These determina-
tions shall consider the other modal classifications within this plan – particularly freight and transit – and re-
fer to the Community Plans, Community Development Code and adopted city plans and codes. Features may
ADOPTED TEXT curb extensions, on-street parking, pedestrian-scale lighting, enhanced pedestrian crossings, traffic calming,
include (but are not limited to): sidewalks with widths greater than those shown in the Washington County
Road Design and Construction Standards, medians, narrower travel lanes and/or narrower pavement widths,

street trees, landscaping, street furniture and public art.

Regional Trail
Regional Trails are included in both the Pedestrian Element and the Bicycle Element. A Regional Trail is a
multi-use pathway that accommodates regional and local utilitarian pedestrian and bicycle trips. Regional
Trails include off-street Pedestrian Parkways and Bicycle Parkways as identified in Metro’s RTP, along with
several existing or proposed multi-use trails in the rural area and a limited number of short pedestrian/bicy-
cle connections that facilitate access to the regional transportation network. Regional Trails serve a trans-
portation function and are encouraged to be designed and constructed in ways that facilitate comfortable,
convenient travel, including the characteristics summarized below.
• Using surface and sub-grade materials and following grading and storm water management
practices that result in a durable, slip-resistant, watershed-friendly surface throughout the year.
• Avoiding flood-prone areas and/or managing storm water to allow year-around operation.
• Providing adequate width, as surrounding context and circumstances allow, accommodating dif-
ferent trail users including people walking, running, cycling, skating, walking dogs and pushing
strollers.
14 Unlike Metro’s RATP/RTP Pedestrian Parkways, Washington County TSP Pedestrian parkways do not include off-street trails. Trails
and roadways are classified separately in the TSP due to the distinct differences in design, operation, maintenance and jurisdiction
management between the two facility types. Off-street Pedestrian Parkways in Metro’s RATP/RTP are included as Regional Trails in
the TSP. On-street Regional Pedestrian Corridors – the second tier of pedestrian routes in Metro’s RATP-RTP – are not included in the
Washington County TSP because the county’s Road Design & Construction Standards are mostly consistent with Metro’s RATP design
guidance for these routes, including provisions for planter strips.
15 Other street design classifications in Metro’s 2014 RTP Regional Design Classifications map include Throughways, Regional Streets
and Community Streets. Washington County design standards for Principal Arterials, Arterials and Collectors are consistent with the
intent of these regional design classifications and are included in the Mobility section of the Washington County TSP Goals, Objectives
and Strategies (Ordinance 768).
