T he Willamette River and the city of Portland are inherently linked. The river is literally andfiguratively the center of the city. It has been instrumental in shaping our economy, culture, andquality of life. Now, on its one hundred and fiftieth birthday, Portland looks to its past, and its
reliance on the river, to guide its future.
Over the last 150 years, Portland’s harbor and central city have flourished in and along the
Willamette River. In 2001, Portland is home to a quarter of the region’s two million people. The Portland
Harbor is the seventh largest export gateway, the largest wheat exporter, and the sixth largest auto port in
the nation. Eleven distinctive bridges cross the Willamette in Portland and twelve riverfront parks line its
banks. In 1998, the national significance of the Willamette River was acknowledged through its designation
as one of 14 American Heritage Rivers.
Despite these achievements, the Willamette River is facing many challenges. Growth and
development have dramatically altered the river channel and its banks. Ironically, urbanization along the
river has slowly reduced public access to its shores. Only a few places remain where people can connect
with the river and, as a result, the community has become detached from Portland’s defining natural feature.
The Willamette has been filled, dredged, redirected, and channeled. Its wetlands have been drained
and filled. Combined sewer overflows, non-point source pollution, and pollutants from various industries
have compromised water quality. In 1998 and 1999, steelhead trout and chinook salmon in the lower
Willamette River and its tributaries were listed as threatened species under the federal Endangered
Species Act (ESA). Cutthroat trout in the lower Willamette River are a candidate species for an ESA listing.
In December 2000, the U.S. Environmental Protection Agency designated a six-mile stretch of Portland
Harbor as a Superfund site—an area of national priority for the cleanup of contaminants. One of Portland’s
greatest challenges in the decades to come will be the restoration of the Willamette River’s health for the
benefit of fish, wildlife, and people.
Today, a new movement is emerging. River Renaissance is the City of Portland’s comprehensive,
multi-objective initiative to respond to the challenges of this new century. The River Renaissance Vision
calls for a clean and healthy river, a prosperous working harbor, vibrant new waterfront districts and
neighborhoods, enhanced access to the river, new recreational opportunities, partnerships for implementation,
and community education. As part of River Renaissance, the Bureau of Planning is coordinating a citywide
effort to create an integrated plan for the land along the Willamette River, develop partnerships between the
public and private sectors to implement the plan, and expand awareness of and commitment to the river’s
future. Portland’s Willamette River Atlas is a tool that will help us as we plan together for a vibrant city
centered on a healthy Willamette River.

The Willamette River Watershed
lies between the Columbia River on the north,
the Calapooia Mountains on the south, the
Cascade Mountain Range on the east and the
Coast Mountain Range on the west. Over 11,500
square miles of land in the Willamette watershed
drain into the Willamette River, making it the tenth
largest river by volume in the continental United
States. The Willamette River mainstem begins
at the confluence of the Coast Fork Willamette
and Middle Fork Willamette Rivers near Eugene.
It flows north for 187 miles, drops 350 feet in
elevation and empties into the Columbia River in
North Portland. Several tributary rivers flow into
the Willamette mainstem, including the Tualatin
River and Clackamas River which are within
the Portland metropolitan area. The location of
the Willamette River in the lower Columbia
River basin defines its role as a seaport and a
spawning ground for seagoing fish, including
salmon and steelhead trout.
Approximately 70 percent of the land in the
fertile Willamette River watershed is forested.
Twenty-two percent of the land is devoted to
agriculture and eight percent is devoted to urban
development. Forested land dominates the
foothills and mountains of the Coast and
Cascade Ranges. Most of the agricultural land is
located in the Willamette Valley and is used to
cultivate annual crops. Approximately 70 percent
of the state’s population of 3,400,000 people
reside in the valley, primarily along the mainstem.

The Willamette River flows through
Portland for 17 miles. Flow rates throughout
the city range from 5,000 cubic feet per second
during the summer to approximately 80,000
cubic feet per second during high flow periods
in the winter and spring. Peak flows after heavy
rains can swell from 200,000 to 400,000 cubic
feet per second.
Figure 2, on page 2, a survey map of the
Willamette River from the 1880s, shows the
natural riverbanks and the numerous lakes that
once surrounded the river. Comparison of the
survey map with the current map in Figure 2
reveals the extent to which the course of the
Willamette River and the shape of its riverbanks
have been altered over the past century. Most
notably, the river once flowed to the east of Swan
Island. Figure 2 also shows the decreasing
number of natural areas surrounding the river due
to encroaching urban development.
A brief glimpse into Portland’s history offers an
explanation for the changing landscape of the
Willamette River. It is believed that for thousands
of years, Native Americans lived in harmony with
the Willamette River, valuing its precious
resources. In the mid-1800s, the first Western
Europeans settled in Portland because the site
offered deep-water moorage for sailing ships
journeying up the Columbia River. Thereafter, mul-
tilayer wooden wharves and docks lined the river-
banks, allowing Portland to flourish economically.

In 1929, the central city wharves were replaced
with the seawall for flood protection. Agricultural
exports from the fertile Willamette Valley
farmlands and a boom in the shipbuilding indus-
try during World Wars I and II defined the
Willamette’s role as a working river. Manipula-
tion of the river and its banks continued as Guilds
Lake and Swan Island were filled with river
sediment to later become industrial districts. For
a short time Swan Island was used as the city’s
airport. Ramsey Lake was also filled and is now
the Rivergate Industrial District. Industry domi-
nated the land use along the Willamette’s river-
banks throughout the 1950s and 1960s. It has
since concentrated in the northern stretch of the
river, which is now known as “Portland Harbor”.
Portland formed a new relationship with the
Willamette River in the 1970s. A thriving and
growing urban core and a desire to reclaim the
riverbanks led to the replacement of Harbor
Freeway with Tom McCall Waterfront Park.
During the same period, Statewide Goal 15
was adopted to protect, conserve, enhance,
and maintain the natural, scenic, historical,
agricultural, economic, and recreational qualities
of lands along the Willamette River as the
Willamette River Greenway.
Today, within the Willamette’s urban setting in
Portland, the river is heavily used for a variety of
activities. The southern portion is largely used
for fishing and recreation. In the north, river-

Over the last century, urban development has dramatically altered the Willamette River and adjacent land.
The shades of blue on the enhanced 1888 survey map, on the left, illustrate the lakes and wetlands that once surrounded the river.
Today, many of these natural areas have been filled for industrial use as illustrated in the map on the right.
dependent shipping and industry are the
predominant activities. The intensely urban
stretch of the river in the center of Portland is
a focal point for the city.
As Portland’s defining natural feature and a hub
for numerous activities, the Willamette River
inspires us to become a city in nature where a
healthy economy and a healthy river can coexist.

Aerial Photo
Map 1, on pages 11 and 12, is a composite digital aerial
photograph (1998) that features the Willamette River corridor.
The aerial photograph provides a view of urban development,
natural features, water bodies, and areas of remaining veg-
etative cover.
The geometric street patterns of downtown Portland and the
inner eastside neighborhoods are visible on Map 1. The aerial
photo shows the river’s edge lined by urban development and
transportation systems, with only a few fragments of natural
areas still intact. Most of the riverfront and bottomland in
North and Northwest Portland are developed as industrial
districts. Southwest of the river corridor, the less developed
areas reflect the rugged topography of the Tualatin Mountains
and public ownership of Forest Park. Additional undeveloped
areas along the southern portion of the river include parts of
Hardtack Island and Ross Island, Oaks Bottom Wildlife Ref-
uge, and Ira Powers Marine Park. The city limits, and various
road and place names, are provided to help orient the reader.
Natural Resources
Map 2, on pages 13 and 14, highlights natural resources
along the Willamette River corridor in the city of Portland. The
map depicts the 100-year flood plain, 1996 flood inundation
areas, bathymetry, streams, habitat sites, and steep slopes.
100-Year Flood Plain
The 100-year flood plain was derived from the Federal
Emergency Management Agency’s (FEMA) Flood Insurance
Rate Maps used for the National Flood Insurance Program.
Land located within areas designated as a 100-year flood
plain has a one-percent chance or greater of being flooded
within any given year.
1996 Flood Inundation
Map 2 shows the areas in Portland affected by a major flood in
February 1996. The areas inundated include portions of most
riverfront parks, areas east of SW Bond Avenue, and various
riverfront industrial, commercial, and residential sites. The 1996
flood inundation area maps were digitized by the U.S. Army
Corps of Engineers using aerial photos taken during the flood.
Bathymetry
River depth, or bathymetry, was derived from two sources.
Main channel bathymetry is from the City of Portland, Bureau
of Environmental Services’ database and was developed
using U.S. Army Corps of Engineers survey information.
Bathymetry for the Swan Island Lagoon, Holgate Slough,
Multnomah Channel, and the Columbia River was developed
from U.S. Department of Commerce, National Oceanographic
and Atmospheric Administration (NOAA) sounding and bridge
clearance maps.
Streams
Stream data is derived from Metro Regional Land Information
System (RLIS) Title 3 stream coverage (August 1999).
The streams on the west side of the Willamette River flow
through steep ravines on their way to the river. Most of these
streams also pass through pipes or culverts before entering
the Willamette River. On the east side, urban development
has buried most of the streams once known to exist. One
exception is Johnson Creek and its tributary Crystal Springs,
located in Southeast Portland.
Habitat Sites
The habitat sites shown on this map were derived from a
Willamette River habitat assessment conducted in 1999-2000.
A survey of each of these areas was conducted to observe
and record habitat quality. Detailed maps and descriptions of
the areas are in the Willamette River Greenway Inventory:
Natural Resources (2001).
Steep Slopes
Metro RLIS information, derived from U.S. Geological Survey
7.5 minute quadrangle maps (1993), was used to map topog-
raphy and determine the location of steep slopes. The steep
slopes depicted on this map are those that exceed 25 percent.
Many of the steep slopes occur in the Tualatin Hills, a small
mountain range rising above Portland’s west side and
running roughly parallel to the river. Along the east side of the
Willamette River, alluvial processes have formed several steep
bluffs. As a result, excellent river viewing areas exist from
Terwilliger Boulevard overlooking North Macadam, Sellwood
Boulevard overlooking Oaks Bottom Wildlife Refuge, Willamette
Boulevard overlooking Albina Yard and Mocks Bottom, and the
University of Portland overlooking the Swan Island Lagoon.

Overview
The maps in this Atlas feature geographic information
of the Willamette River corridor in Portland. They
present an overview of environmental, regulatory,
recreational, land use, and ownership information. Each
map is represented at a scale of 1:2000 feet. The maps
show taxlots (Multnomah County Assessment and
Taxation, last updated in July 2000); freeways (Bureau
of Planning, from City of Portland photogrametrics,
1989–1994); railroads, and generalized outlines of the
Willamette River, Columbia Slough, and Smith and
Bybee Lakes (Metro Regional Land Information System,
1994). The City of Portland, Bureau of Planning’s
Geographic Information System (GIS) generated the
existing information portrayed in these maps.
Layout
Descriptions for the eight maps occur on pages 3–10.
The maps are grouped at the end of the Atlas on
pages 11–26 so that they may be easily compared.

As illustrated in Figure 3, the riverbanks
are mostly non-natural. Rip rap, structures,
unclassified fill, and sea walls comprise
approximately 72 percent of existing banks
along the Willamette River within Portland’s city limits.
Twenty-six percent consist of natural and river beach banks.
Bio-technical and bio-engineered banks constitute only two percent of existing bank types,
but that percentage is expected to grow over time as riverfront redevelopment and restoration occurs.
Riverbank composition data was provided by GreenWorks, PC Landscape Architecture, Portland.
Some information was updated by the Bureau of Planning in 2001.

Map 3, on page 15 and 16, shows the Willamette
riverbank composition, contaminated sites, and
the location of documented stormwater outfalls.
Riverbank Composition
The riverbank composition data were produced
for the City of Portland based on field surveys
conducted in 1999. The Bureau of Planning
updated the information in 2001. The riverbank
composition is classified into seven generalized
categories described in Table 1.
Outfalls
Outfalls are discharge pipes that release storm-
water, stream water, wastewater, or a combina-
tion of the three into larger water bodies such as
rivers and lakes. Map 3 shows the location of
documented outfalls along the Willamette River.
The outfall information was obtained from a City
of Portland, Bureau of Environmental Services’
May 2000 inventory and from a survey of unre-
corded outfalls conducted for the Bureau of
Planning in March and November, 1999.
Portland Harbor Investigation
and Clean-up Sites
The sites identified on Map 3 are undergoing
cleanup or investigation for environmental
contamination in the Portland Harbor. This
information was provided by the Oregon De-
partment of Environmental Quality. These sites
are located within a six-mile stretch of the river
between Sauvie Island and Swan Island.
Sediments found in this area of the Portland
Harbor contain detectable levels of contami-
nants, including PCBs, pesticides, herbicides,
metals, dioxins, arsenic, chromium, and
petroleum-related hydrocarbons.
Unclassified Fill
Areas along banks that have been filled over time with miscellaneous unconsolidated
materials consisting of debris of various types.
Structures
Banks covered by piers, wharves, supporting docks, buildings, and other structures.
Bio-technical and Bio-engineered Banks
Banks that rely on vegetation and other materials for bank stability. Bio-technically
engineered banks incorporate vegetation as a visible component of the bank, but inert
and man-made materials provide the physical structure that ensures bank stability.
Bio-engineered banks rely on vegetation and natural fabric materials for bank stability.
Sea Wall
Constructed, impervious vertical walls, generally composed of concrete, timber, or
sheet pile that extend below ordinary low water.
River Beach
Shallow shoreline, usually with a grade of 20 percent or flatter, that consists of sand, silt,
fine gravel, or other sedimentary deposits. In some locations, the beach may be visible
below other bank conditions only at low water. In other locations, the beach may extend
gradually up to the adjacent flood plain.
Rip Rap
Banks armored with rocks of various sizes; generally devoid of vegetation but
may be covered with trees and shrubs.
Natural
Relatively undisturbed banks composed of rock outcrops or native earth material.
Vegetative cover varies; both living and dead vegetation may be present.

located in the vicinity of the Willamette River
in Portland. The map features bikeways,
Willamette Greenway Trail segments, concep-
tual trails, parks, public boat docks, boat
launches, viewpoints, greenway view corridors,
and scenic view vantage points.
Willamette Greenway Trail
The Willamette Greenway Trail displayed on
this map represents the alignment proposed in
the City of Portland’s Willamette Greenway Plan
(1987) and the various stages of trail completion
to date. The trail information was obtained from
the Willamette Greenway Trail Inventory (1999)
conducted by the Bureau of Parks and Recre-
ation. The Bureau of Planning updated the
information in 2001. The greenway trail is
planned as a 41-mile pedestrian and bicycle
trail, extending along both sides of the river as a
combination of on-street and off-street paths.
Conceptual North Portland Trails
Map 4 also shows various conceptual trails in
North Portland which are discussed in the Draft
North Portland Willamette Greenway Trail Feasi-
bility Study (2000). The draft study, conducted
by the Bureau of Parks and Recreation, ana-
lyzes the feasibility of implementing these trails
in the future. The trails extend along a stretch of
mostly waterfront properties in the Central East-
side, Swan Island and North Portland Areas.

and open space GIS coverages, and the Draft
Willamette River Greenway Inventory: Recre-
ational Resources and Visual Character (2000)
conducted for the Bureau of Planning. Twelve
parks currently provide public access to the
Willamette River in Portland. From north to
south, these parks include Kelley Point Park,
Cathedral Park, McCarthy Park, Eastbank
Esplanade, Tom McCall Waterfront Park, South
Waterfront Park, Cottonwood Bay, Willamette
Park, Oaks Bottom, Butterfly Park, Sellwood
Riverfront Park, and Ira Powers Marine Park.
The map shows the eastside neighborhoods
dotted with numerous community-oriented parks
and a regional park in the Smith and Bybee
Lakes area. Beyond the river’s edge on the west
side, there are large regional parks including
Forest Park, Washington Park, and Tryon Creek
State Park.

Public Boat Launches
Boat launches identified in Map 4 indicate areas where facili-
ties exist for the public to launch boats or other watercraft into
the Willamette River in Portland. The Draft Willamette River
Greenway Inventory: Recreational Resource and Visual Char-
acter (2000) identifies six publicly-owned boat launch sites.
They are located at Cathedral Park, Swan Island Lagoon,
McCarthy Park, South Waterfront Park, Willamette Park, and
on the Columbia Slough. With the exception of South Water-
front Park, McCarthy Park, and the Columbia Slough, these
sites provide ramps for motorized boats. Only non-motorized
boats (such as canoes and kayaks) may be launched at South
Waterfront Park, McCarthy Park, and the Columbia Slough.
Other privately owned boat launches in Portland, which do not
appear on Map 4, provide additional places for the public to
launch boats and other watercraft.
Public Boat Docks
Boat docks on Map 4 indicate areas where City-owned facili-
ties exist for the public to dock boats or other watercraft along
the Willamette River. The Draft Willamette River Greenway
Inventory: Recreational Resources and Visual Character
(2000) identifies eight boat docks owned by the City of Port-
land. They are located at Cathedral Park, Waterfront Park
(one at SW Ankeny Street and one at SW Salmon Street), the
Eastbank Esplanade, SE Madison Street, Willamette Park,
Sellwood Riverfront Park and Butterfly Park. The dock at SW
Salmon Street, owned by the City of Portland’s Bureau of
Parks and Recreation, is leased to the Portland Spirit and
does not allow for public docking. Other privately owned docks
in Portland, which do not appear on Map 4, provide additional
places for the public to dock.
Developed and Undeveloped Viewpoints
Viewpoints are public places along the Willamette Greenway
Trail that provide resting or stopping points to view the river
and surrounding environment. The Willamette Greenway Plan
(1987) identifies sites that require the construction of public
viewpoints as part of new development or redevelopment. On
Map 4, viewpoints are classified as developed and undevel-
oped. Undeveloped viewpoints are those that are designated
in the Willamette Greenway Plan (1987) and have not yet
been built.
Greenway View Corridors
View corridors are public or private rights-of-way that provide
unobstructed views to the river from nearby neighborhoods or
business districts. The Willamette Greenway Plan (1987)
designates 23 rights-of-way as view corridors. Thirteen of the
designated greenway view corridors are on the west side of
the river in the central city except for one just south of the
Hawthorne Bridge. The remaining view corridors are located
south of the Ross Island Bridge, in the vicinity of Willamette
Park and Sellwood Riverfront Park.
Scenic View Vantage Points
Scenic view vantage points are places that have clear views of
the city, mountains, or bridges. The vantage points identified on
Map 4 are documented in the Scenic Resources Protection Plan
(1991). These are generally located in parks or along public
rights-of-way and may, or may not, be developed as viewpoints.

Hierarchy of Land Use Regulations
Regulations in the Portland Zoning Code are organized into a hierarchy. For example,
overlay zone regulations supercede base zone regulations on property that is subject to
overlay zone regulations. If a property is subject to both overlay zone and plan district
regulations, plan district regulations take precedence. NRMPs take precedence over
environmental overlay zone regulations.Base zones and plan districts are illustrated
on Map 5. Overlay zones and natural resource management plan (NRMP) areas are
shown on Map 6.

Map 5, on pages 19 and 20, depicts the base zones and plan
districts of the Portland Zoning Code near the Willamette River.
Base Zones
Base zones regulate general land use patterns envisioned
for the city. The source of this information is the Bureau of
Planning’s GIS zoning data (July 2000) that is used for
Portland’s official zoning maps. All properties in the city are
mapped with base zone designations that fall into the general
categories of single and multi-dwelling residential, commercial,
industrial, employment, and open space. These base zone
groupings are comprised of more specific categories listed in
Table 3 below. Each base zone has a general land use specifi-
cation but also permits other uses. For example, commercial
zones allow residential uses. This map does not represent
existing land uses but rather, the desired land use pattern set
out in the goals and policies of Portland’s Comprehensive Plan
(1999). The land use pattern illustrated on the map is imple-
mented through the Portland Zoning Code, Chapter 33.100–
33.140. The code also sets development, density, and design
standards for new development and property alterations.
Plan Districts
Plan districts are established to address issues unique to a
specific area in the city when base zone and overlay zone
regulations are inadequate to achieve desired results. The
unique characteristics of the areas may be based on factors
such as environmental, economic, or historic attributes.
Each plan district has its own specific set of regulations that
supercede base zone and overlay zone provisions to achieve
district-specific objectives. Those directly adjacent to the river
are the Central City Plan District, the Swan Island Plan District,
and the Macadam Plan District. Plan district regulations are
implemented through the Portland Zoning Code, Chapter
33.500–33.585.

Map 6, on pages 21 and 22, illustrates the scenic, environ-
mental, design, and greenway overlay zones, seven urban
renewal districts and the natural resource management plan
areas surrounding the Willamette River.
Overlay Zones
Overlay zones carry out Portland’s Comprehensive Plan goals
and policies through regulations that address the unique
characteristics of specific areas throughout the city. Overlay
zones are applied in conjunction with base zones and alter
base zone regulations to meet specific goals. The information
displayed on the map is derived from the Bureau of Planning’s
GIS zoning data. Overlay zone regulations are implemented
through the Portland Zoning Code, Chapter 33.400–33.480.
Scenic Resource Overlay Zones
The scenic resource overlay zone is a zoning tool used to
implement the policies of Portland’s Scenic Resources Protec-
tion Plan (1991). This overlay zone identifies where specific
development standards for view corridors and scenic corridors
are applied in relation to new development or redevelopment.
Scenic resource overlay zones are implemented through the
Portland Zoning Code, Chapter 33.480.

Environmental Overlay Zones
The environmental overlay zones protect natural resources
and functional values identified by the City as providing public
benefits. Large areas subject to environmental overlays in-
clude Smith and Bybee Lakes and Forest Park. Natural areas
located along the Willamette River are protected through the
Greenway River Natural Overlay Zone and by reference to
the Lower Willamette River Wildlife Habitat Inventory. Environ-
mental overlay zones are implemented through the Portland
Zoning Code, Chapter 33.430. The environmental overlay
zones are as follows:
Environmental Protection Overlay Zone — Provides the highest
level of protection to the most important resources and func-
tional values identified by the City. Development in this zone is
only approved in rare and unusual circumstances.
Environmental Conservation Overlay Zone — Conserves impor-
tant resources and functional values in areas where they can
be protected while allowing environmentally sensitive urban
development.
Natural Resource Management Plan Areas
Map 6 illustrates both the Smith and Bybee Lakes and the
Forest Park Natural Resource Management Plan Areas.
The Forest Park Natural Resource Management Plan (1995)
protects Forest Park’s natural resources and enhances its
recreational and educational resources. The Smith and Bybee
Lakes Natural Resource Management Plan (1990) seeks to
implement the management framework, identify funding, and
institute the processes needed to restore and maintain the
Smith and Bybee Lakes in their original natural condition.
Natural resource management plan areas are implemented
through the environmental overlay zone, Chapter 33.430 in
the Portland Zoning Code.
River Recreational
Encourages river-dependent and river-
related recreational uses that provide a
variety of public access opportunities
to and along the river, and enhances the
river’s natural and scenic qualities.
River Industrial
Encourages and promotes the development
of river-dependent and river-related
industries that strengthen the economic
viability of Portland as a marine shipping
and industrial harbor, while preserving and
enhancing riparian habitat and providing
public access where practical.
River General
Allows for uses and development that are
consistent with the base zoning that allow for
public use and enjoyment of the waterfront,
and that enhance the river’s natural and
scenic qualities.
River Natural
Protects, conserves, and enhances land of
scenic quality or of significant importance as
wildlife habitat.
FIGURE 6:
Greenway Overlay Zones
Greenway Overlay Zones
The greenway overlay zones are intended to protect, con-
serve, enhance, and maintain the natural, scenic, historical,
economic, and recreational qualities of the lands along the
Willamette River. The greenway overlay zones include river
natural, river general, river recreational, and river industrial.
Descriptions and map notations are described in Figure 6.
Greenway overlay zones are implemented through the
Portland Zoning Code, Chapter 33.440.
Design Overlay Zones
The design overlay zone encourages greater urban and
architectural design sensitivity in parts of the city with important
scenic, architectural, or cultural value. This overlay zone
applies to design districts and sub-districts with established
design guidelines. The Central City and the Macadam Avenue
corridor are examples of areas, adjacent to the river, that
are subject to established design guidelines. Design overlay
zones are implemented through the Portland Zoning Code,
Chapter 33.420.
Urban Renewal Districts
Map 6 also shows the urban renewal districts around the
Willamette River. The purpose of urban renewal is to help
communities improve and redevelop areas that are deterio-
rated, unsafe, have a lack of infrastructure such as streets,
utilities and sidewalks, or have extensive vacant and under-
utilized property. The revitalization efforts are paid for by
urban renewal bonds, which are eventually paid off by the rise
in property tax revenue from the urban renewal area. The
urban renewal districts that are shown on Map 6 include:
Downtown Waterfront, South Park Blocks, Central Eastside,
Oregon Convention Center, River District, North Macadam,
and Interstate Corridor.

Percentage of Linear Riverfront
in Public and Private Ownership
Map 7, on pages 23 and 24, illustrates public and private land
ownership. This information was obtained from the Multnomah
County Tax Assessor’s records as of July 1999. The Bureau
of Planning updated this information in 2000. Ownership
categories include private landowners with more than 50 acres
either completely within or intersecting the greenway overlay
zone. The map also shows public land ownership throughout
the Willamette River corridor. Public landowners include the
City of Portland, Multnomah County, Metro, the State of Oregon,
the U.S.A., and the Port of Portland as listed in Table 4.
Private land owners are shown in Table 5.
Figure 7 shows the percentage of linear riverfront owned by
public and private interests. Approximately 56 percent of the
riverfront (20.8 miles) is in public ownership while the remain-
ing 44 percent (17.2 miles) is in private ownership.

Map 8, on pages 25 and 26, focuses on the
waterfront land use pattern. Industry is the
predominant use, particularly in the working
harbor downstream of the Broadway Bridge.
To illustrate the marine industrial context of
the harbor, the map shows types of industrial
uses, names of cargo dock operators, and the
associated network of railroads and truck
routes. In-water structures (such as docks),
properties with river-dependent uses (those that
require access to the river for transportation or
recreation), and existing and proposed light rail
and streetcar lines are also shown. The land
use inventory area generally extends from the
river to the nearest continuous street or railroad.
Land Uses
Map 8 depicts primary land uses, in contrast to
accessory uses. Primary uses are the activities
of chief importance on a parcel, such as manu-
facturing or residential; while accessory uses
are incidental to the primary use, such as a
parking lot or dormitory on a university campus.
The Bureau of Planning developed the land use
information using Port of Portland publications
(1997 Portland Harbor Land Use Inventory;
South Rivergate: Here’s Who’s Here, 1992),
Multnomah County Assessment and Taxation
data (October 1999), aerial photographs (1998),
and site observation. The land use categories
shown on the map are described in Table 6.
River-Dependent Uses
Properties with a use that must be located on,
in, or adjacent to the river, because the use
requires river access for waterborne transporta-
tion or recreation, are shown on the map as
river-dependent uses. Examples include marine
cargo terminals, ship repair yards, barge
services, dredge facilities, U.S. Coast Guard
facilities, and recreational boat marinas.
Mining
Minerals extraction for off-site use. Gravel extraction at
Ross Island Lagoon and Hardtack Island is the only mining
use in the inventoried area.
Residential
Household and group living facilities. Tenancy is arranged on
a month-to-month or longer basis. Houseboats are also a
residential use.
Commercial
Retail trade and services for the general public, offices,
and lodging.
Mixed use
Combination of residential and commercial or industrial uses
on a parcel.
Institutions
Community services (typically by public or non-profit
providers), schools, colleges, medical centers, and religious
institutions. Riverfront examples include Oregon Museum of
Science and Industry and the University of Portland.
Utilities, parks, and open spaces are shown in separate
categories and not as institutions.
Vacant
Entire parcels with no usable buildings or improvements.
Most examples are undeveloped land. Other examples
include improved properties that are constrained by
inconsistent zoning, site contamination, or inadequate
infrastructure. Vacant does not include parcels that are
actively used for outdoor storage of machinery, equipment,
products, or by-products. It does not include parcels with
usable buildings that are temporarily unoccupied.
Utilities
Infrastructure services, such as those related to water
supply, sewer, electrical, communication, natural gas, and
solid waste.
Industrial Services
Repair or service related to machinery, equipment, products,
or by-products. Waterfront examples include ship repair,
barge services, and dredge facilities.
Railroads
Main freight railroad lines, rail yards, and associated
waterfront properties owned by railroad operators.
Warehousing
Storage, distribution, and wholesale trade of goods,
except for marine cargo facilities and rail yards which
are categorized separately. These facilities typically rely
on trucks for freight distribution.
Marine Cargo
Loading or unloading of ships and associated storage and
distribution of cargo. Examples include the Port of Portland
terminals, private grain elevators, and petroleum storage
facilities.
Manufacturing
Manufacturing, processing, fabrication, or assembly of
goods. Examples in the inventoried area include
scrapmetal processing, cement production, fiber optic cable
manufacturing, semiconductor manufacturing, and
specialty chemicals manufacturing.

Freight Network
Supporting Portland’s economic role as an
industrial and freight distribution center, the
working harbor area is a hub for marine, rail, and
truck transportation. Map 8 shows the harbor
area, main freight railroad lines, rail yards, and
regional truck routes. The harbor’s 40-foot
deep shipping channel for oceangoing vessels
is maintained along the Willamette River to
the Broadway Bridge, encompassing about two
thirds of the Willamette’s length through
Portland, and along the Columbia River to the
Port of Portland Terminal 6. Barge transportation
extends further up-river on the Willamette and
Columbia Rivers.
Map 8 shows the main and branch rail lines
designated on the Regional Freight System
map in the 1999 Regional Transportation Plan.
Two transcontinental railroads operate along
both sides of the harbor. The Union Pacific main
line follows the river’s east side between the
Hawthorne Bridge and Swan Island, with spur
lines extending to other parts of the harbor.
The Burlington Northern-Santa Fe main line
through Portland extends along the river’s west
side into the Northwest Industrial District, cross-
ing at the Railroad Bridge. Map 8 also shows the
associated rail yards used for railcar switching,
loading, and assembling trains.
The trucking network depicted on Map 8 shows
regional truck routes, major truck streets, minor
truck streets, and truck district streets (Transpor-
tation Element of the Portland Comprehensive
Plan). Interstates 5 and 84 intersect in Portland
near the river, and connect with highways and
truck streets that serve the industrial districts
along Portland Harbor.
