4 PORTLAND CITYWIDE DESIGN GUIDELINES
INTRODUCTION
Portland’s ecological setting, nestled between the Cascade and Coast mountain ranges and carved by the
Columbia and Willamette Rivers, offers abundant beauty and a climate that beckons people outside, along
its streets, parks, and trails. Development of the built environment over time has further influenced the
Portland landscape, shaping how the city looks and functions today. Architecture and site design impact
people’s interaction with the city, and design can create positive experiences as places continue to trans-
form. Future development, and the treatment of our built and natural landscape, has the potential – and
the responsibility – to create a better city for all Portlanders.
Portland has received national and international acclaim for supporting a high-quality built environment
through planning and urban design. This is due, in part, to its long-standing tradition of design review, which
has resulted in pedestrian-oriented and context-responsive development in Portland’s active and vibrant
urban spaces.
As the city has evolved, so have our aspirations. The goals and policies Portlanders set out in the 2035 Com-
prehensive Plan envision a prosperous, equitable, healthy and resilient city. They envision a city designed for
people and a city built in harmony with nature.
Design review will continue to play an important role in shaping the built environment that serves a broad
range of people, from the general public –– to future residents, workers, and visitors. It offers an opportunity
for designers to innovate and be creative, exploring new methods and designs that are responsive to climate
and context.
Design review offers direct and timely public engagement in the
development review process. Successful collaboration and dis-
cussions during the design review process results in projects that
provide opportunities for inclusion, foster social interaction, and
create places where people feel connected to each other and to
the place they inhabit. Such projects will inspire long-term stew-
ardship and community investment across the city.
The City’s design program upholds Portland’s key design-related
values, or “tenets.” The three tenets are the framework for the
Portland Citywide Design Guidelines:
Build on context
Contribute to the public realm
Promote quality and resilience
These tenets do not supersede adopted policies, guidelines, and
regulations, but rather provide a lens through which to apply
them. They are rooted in the 2035 Comprehensive Plan, and they
serve to help decision-makers and the public evaluate a propos-
al’s response, using a set of qualitative, value-based regulations.
Thoughtful application of the design guidelines through the design
review process moves us closer to achieving our collective vision
for Portland.
PORTLAND CITYWIDE DESIGN GUIDELINES 5
I. DESIGN OVERLAY ZONE IN PORTLAND
BACKGROUND
The Design Overlay Zone (d-overlay) was established in the late 1950s in
Portland’s downtown, with the purpose of “conserving and enhancing the
appearance of the city of Portland, especially in areas of existing or poten-
tial scenic value, of historical note, of architectural merit, or for interest to
tourists.”
After the 1972 Downtown Plan, it was reinforced with the creation of
the Downtown Design Guidelines. At the time, Portlanders recognized
and intentionally tried to resist a national trend of the abandonment of
downtowns, which resulted in a lack of street life and vitality in city cores
throughout the country. Building design in the 1950s and 1960s had gen-
erally responded to the dominance of the automobile rather than building
on and supporting a rich urban environment for pedestrians. The creation
of new design guidelines and the process of design review in Portland
brought attention to the design of buildings and their role in contributing
to the public realm and the character of downtown districts. Both the
review process and the tool were intended to encourage flexible, creative
building designs that reinvigorated downtown’s pedestrian experience
while promoting quality architecture.
In the 1990s, design overlay zone expanded to outside the Central City
– into the Albina neighborhood, and more guidelines were created to
respond to areas with specific characteristics that were not the same as
downtown. Guidelines were written to both enhance the character of
Portland’s neighborhoods and support a pedestrian environment. The
Albina Community Plan adoption prompted the City of Portland to create
a two-track system to offer developers a clear and objective alternative to
design review.
Over the years, updated base zones have improved design of buildings at
the street level with regulations for new development such as main entry,
ground floor window, and outdoor area requirements. At the same time,
the City has added areas to the d-overlay zone with incremental adoption
of neighborhood plans and planning for high-capacity transit.
In 2018, with the adoption of the 2035 Comprehensive Plan, the City ex-
panded the Design overlay zone to all town centers and inner ring neigh-
borhood centers. In doing this, the City recognized that areas expected
and planned for growth and increased development warrant an added
focus on design to support its long-range vision.
Design review has evolved over time, along with zoning regulations and
new design guidelines and processes, all of which have raised the bar on
design excellence and meaningful public engagement. It will continue to
encourage creativity and public participation, inspiring new development
to support Portlanders as the city changes.
6 PORTLAND CITYWIDE DESIGN GUIDELINES
TWO-TRACK SYSTEM
Design overlay (d-overlay) is typically added through a legislative planning project or quasi-judicially in
conjunction with more intense base zone changes. The Design overlay zone is shown on the Official Zoning
Maps with a letter ‘d’ map symbol.
For new development and large alterations outside of the Central City, Portland uses a two-track system
within the Design overlay zone. The two tracks are separate options for approving development proposal:
the Objective Track and the Discretionary Track, or design review.

The three tenets are benchmarks that frame how the

Guidelines are written. While the standards provide
clear and objective measures, and the guidelines
provide criteria that offer flexibility and encourage
innovation, these parallel regulations both strive to
achieve the same outcomes rooted in these three
tenets.

II. ABOUT THE DESIGN GUIDELINES
PORTLAND'S CITYWIDE CONTEXT
Paramount to understanding the design guidelines is recognizing and
acknowledging the greater context of Portland, Oregon.
Situated at the confluence of the Willamette and Columbia Rivers,
Portland lies midway between the Cascade Range to the east and the
lower Coast Range to the west, each about 30 miles away. Its skyline is
dominated by two Cascades volcanoes: Mount St. Helens and Mount
Hood. The city’s location at the northern end of the fertile Willamette
Valley, its long growing season, moderate annual temperatures, and
rainy winters have resulted in a rich and diverse ecosystem that have
sustained people for thousands of years.
Though the city’s overall geography and its history are intertwined and
unique, Portland’s neighborhoods and streets each have distinct histo-
ries and geographies that are as rich and diverse as its natural setting.
It should be acknowledged that development has played a role in eras-
ing the uniqueness and culture of the city’s beloved places, upholding
or exacerbating racial disparities, and worsening barriers to opportu-
nities for communities of color and under-represented communities.
These guidelines should be used to ensure that places undergoing
change will be inclusive and foster a sense of place and belonging. The
design response should intentionally promote an anti-racist built envi-
ronment that honors and preserves the localized history and culture.
As the city grows, development should be designed to recognize that
one size does not fit all across Portland’s neighborhoods.
PORTLAND CITYWIDE DESIGN GUIDELINES 9
URBAN DESIGN FRAMEWORK
Portland’s 2035 Comprehensive Plan provides a blueprint to ensure that
new development responds to its context: the Urban Design Framework.
The Urban Design Framework (UDF) provides four distinct layers:
Pattern areas – Western, Inner, and Eastern Neighborhoods;
Rivers (Pattern Areas also includes the Central City, where these
guidelines do not apply.)
Centers – Town Centers and Neighborhood Centers (Centers also
include the Central City and Gateway Regional Center, where
these guidelines do not apply.)
Corridors – Civic Corridors and Neighborhood Corridors
Transit stations – Center Transit Stations, Transit Neighborhood
Stations, Employment Stations, and Destination Stations
Of the four layers, Pattern Areas apply to all sites. Pattern Areas reflect
general existing conditions that give guidance for how sites should
develop based on physical and natural characteristics, while building a
future that is compact, transit-oriented, and designed for people.
Natural resources make up much of Portland’s land area, providing safe,
healthy places for migratory fish and wildlife species to live in and move
through the city. Urban habitats encompass the city’s most valuable and
unique natural features – the rivers, streams, and sloughs, wetlands,
buttes, and large forested areas and parks. Other urban habitats are wo-
ven throughout the built environment, including street and yard trees,
ecoroofs, landscaping, parks, trails, and bridges – which provide oppor-
tunities for wildlife and maintain Portland’s distinctive natural character.
The UDF guides new growth to Centers, Corridors, and Transit Station
areas, where people can access jobs, housing options, services, and
transit connections. These areas reflect an aspirational future where
new development should respond to the opportunity presented by its
location within major areas of growth and natural setting.
To ensure that these areas function successfully and foster strong and
inclusive communities, new development should be designed to support
the desired character of growing centers, corridors, and transit stations,
while building on positive physical and natural characteristics that are
rooted in the city’s Pattern Areas.
PATTERN AREAS
Portland’s pattern areas are a formal acknowledgment that the city’s
natural and built landscapes aren’t all the same. They have distinct char-
acteristics that have been influenced by both the natural environment
and how or when these parts of the city were developed. Pattern areas
are described in detail in Guideline 01.

part of design review. They also intend to serve as parameters for discus-
sion and deliberation.
During the design review process, applicants are responsible for explain-
ing, in their application, how their proposed design meets each guide-
line.
The public is encouraged to weigh in on the proposed design, based on
the guidelines.
Decision-makers must tie their comments and responses, and ultimate-
ly their decision, to the guidelines. Discussion and deliberation should
be organized around and focused on whether the proposal meets the
guideline or does not meet the guideline.
Proposals that meet all the applicable guidelines will be approved. Pro-
posals that do not meet all of the applicable guidelines will be denied.
If the decision-maker approves the proposed design, they may add con-
ditions to their approval, which require revisions to the design to ensure
the proposal’s compliance with the guidelines.

PORTLAND CITYWIDE DESIGN GUIDELINES 1 901 BUILD ON THE CHARACTER, LOCAL IDENTITY, AND
ASPIRATION OF THE PLACE.
Heart of Foster, SE Foster and SE 73rd
BACKGROUND
Development should complement the place it inhabits. Place refers to an area’s qualitative physical
characteristics, such as the natural and built environment, and to an area’s social characteristics, such as
the histories, cultures, and needs of the communities it serves.
By responding to place, development in Portland can represent and support the diversity of its
neighborhoods and the people who will continue to be a part of its evolution.
Portland’s pattern areas provide a basis for understanding the context of the city’s past, present and
future and the characteristics and aspirations of distinct and unique places. Building on the local identity
of a pattern area is also an opportunity to engage the community in discussion about the contributions
a development makes to the neighborhood, and a precaution against increasing uniformity and loss
of authenticity across the city. Over time, the changing face of new development should augment the
character and nature of a place rather than deplete it.
20 PORTLAND CITYWIDE DESIGN GUIDELINES01
At the citywide scale, the Urban Design Framework described in the Introduction gives a blueprint for
future development in areas across the city. Development should contribute to the future aspiration out-
lined in the Urban Design Framework, as well as the context of the area’s historic and cultural past and the
character of its present. Pattern areas should be a starting place for applicants in defining the character, local
identity and aspiration.
The pattern areas are
described on the following
pages. The UDF also gives
a framework for anticipated
growth within centers, cor-
Columb
ridors, and transit station ia River

in the Introduction. These illa

The following descriptions
identify key positive char-
acteristics that are related
to future development and
design priorities in these
areas.
The Western Neighborhoods are distinguished by the terrain of
Portland’s west hills and a network of trails, tree-covered forests,
and streams.
In Western Neighborhoods, new development should minimize
impacts on the area’s streams and slopes with sensitivity to the
site’s topography. It should preserve and enhance the area’s
surface water, wetlands, habitat areas, and tree canopy. New
development should provide connections to pedestrian trails and
pathways.
Building forms can take advantage of opportunities provided by
irregular spaces carved from curvilinear streets, changes in topog-
raphy, and site vistas by providing places that stitch together hab-
itat and places for viewing and gathering. While moving toward a
more compact, less auto-oriented urban form, architecture can
take cues from prevailing post-war language found in Western
centers and along corridors and consider features such as low-
slung pitched roofs, landscaped or set-back frontages, and court-
yard entries and vista points that are shaped to fit the topography.

of e isting older buildings and pa erns while adding density.
Large sites in nner eighborhoods should break up building massing, al-
low multiple connections and entries, and support a strong, active street
wall. ew development should reinforce Portland s commitment to active
transportation and transit ridership through bicycle amenities and stop-
ping and waiting areas.

SURROUNDINGS.
Sellwood/Moreland, SE Milwaukie and SE Claybourne
BACKGROUND
New development must respond to its surroundings, both abutting sites and sites located directly across
the street. Designers should consider how to harmoniously relate to sites with lasting qualities and
characteristics, such as neighboring designated historic landmarks, historic resources, natural resources,
open spaces, and trails. In addition, new development should balance its response to lower-density
zoning, recognizing that the city will grow and evolve over time.
New Development should forge positive relationships with neighboring sites through conscientious
massing, transitions, and connections. On large projects, building scale should respond to adjacent
conditions. Smaller contextual responses include site edge treatments such as buffering and landscaping,
and architectural features such as placement of openings and ornamental details.

INTEGRATE AND ENHANCE ON-SITE FEATURES AND
OPPORTUNITIES TO CONTRIBUTE TO A LOCATION’S
UNIQUENESS.
Hillsdale, SW Capitol Highway and SW 26th
BACKGROUND
Building on context includes seeking and drawing inspiration from the existing conditions of the
development site itself. A project’s architecture and programming should respond to natural features,
physical features, and historical features of the site, where applicable.
Natural features include topography, views, sightlines, solar and wind orientation, trees and vegetation.
These features add value and should be woven into the site and building design.
Physical features refer to site dimensions, boundary limitations, and any structures or buildings that will
remain with redevelopment. Complementary additions to existing older buildings enhance the evolving
urban fabric and connect different periods of Portland’s history, while moving towards a desired future.
Development should build upon and reflect site and building history, passing along the narrative of the site.
Specific responses to natural features include important, and incorporating these features not
