Portland Oregon

Portland (/prtlnd/ or PORT-lnd/) is the largest city in Oregon, the U.S. state. It’s also a port in the Pacific Northwest. Portland, Oregon’s largest county, is home to Multnomah County. It is situated at the intersection of the Columbia and Willamette rivers. Portland, with a population of 652,503 people, is the 26th most populous US city, sixth on the West Coast and second in the Pacific Northwest after Seattle. Portland’s metropolitan statistical area (MSA), has approximately 2.5 million residents, making it the 25th most populous US city. Nearly half of Oregon’s residents live in the Portland metropolitan area.

The Oregon colony was named after Portland, Maine and established shortly after the completion of the Oregon Trail in 1840s. The city’s location near water made it easy to move commodities. The lumber industry was an important part of the city’s early economy. At the beginning of the 20th century, the city was known as a hub for organized crime and racketeering. As the city’s economy experienced an industrial boom, its hard-edged reputation began fading. Portland’s progressive political views earned it a reputation for being a counter-culture hotspot. This was in the 1960s.

A mayor and four commissioners lead the city’s commission-based administration. Metro is America’s first publicly elected metropolitan planning body.

The climate of Portland is hot and dry in the summers, and cold and wet in winter. Portland is known for being the “City of Roses”, and this climate is ideal for rose cultivation. Pre-history

Portland, the territory that would eventually become it was, was inundated by the collapse of glacial dams at Lake Missoula in Montana during the ancient era. The Willamette Valley was inundated with water from 300 to 400 feet (91 – 122 m) during the last ice age.

Before the arrival of American immigrants, the country was occupied by two indigenous Chinook tribes – the Multnomah or the Clackamas.

In 1805, Meriwether Lewis (or William Clark) was the first to record the Chinook residents of the land. Before European contact, the Portland Basin was the most densely populated area on the Pacific Coast. It is located in the lower Columbia River and Willamette River valleys.

Portland’s Establishment

In the 1840s, the Oregon Trail brought many pioneer settlers to Willamette Valley. Many settled in nearby Oregon City.

A new town was then built ten miles away from the Willamette River mouth, about midway between Oregon City, Fort Vancouver and Fort Vancouver by the Hudson’s Bay Company. This hamlet was known once as “Stumptown” or “The Clearing” because of the number of trees that were cut down in order to make room for its expansion. William Overton, an 1843 colonialist, saw the potential of the new settlement but did not have the resources to register a land claim. Overton offered to split half the land of 640 acres (2.6 km2) with Asa Lovejoy, Boston, for 25 cents.

In 1845, Overton sold half of the claim to Francis W. Pettygrove, Portland, Maine. Lovejoy and Pettygrove wanted to rename The Clearing after their respective cities (Boston for Lovejoy, Portland for Pettygrove). The coin toss was used to settle the dispute. Pettygrove won two of the three times and Portland got its name. The Oregon Historical Society has on display the currency used in the judgment. It is now called the Portland Penny. Portland was home to approximately 800 people when it was founded on February 8, 1851. It had a steam sawmill and log cabin hotel. There was also a weekly newspaper, The Weekly Oregonian. A large fire broke out in downtown Portland in August 1873. It burned twenty blocks of West Willamette River west bank along Yamhill and Morrison Streets. The damage was $1.3 million, which is roughly equivalent to $29.4 millions today. The population had risen to 17,500 by 1879 and to 46,385. [26] In 1888, Portland was the first West Coast steel bridge to be opened. This was the precursor to the 1912 Steel Bridge that is still in existence today. Henry Pittock’s widow Georgiana Pittock founded the Portland Rose Society, 1889. As Portland prepared for the 1905 Lewis & Clark Centennial Exposition, the idea to make Portland a “Rose City” began.

Portland’s proximity the Pacific Ocean via the Columbia and Willamette rivers, along with its easy access to Tualatin Valley via the “Great Plank Road”, (currently US Route 26), gave it an advantage over other nearby ports. It flourished quickly.

Portland was the Pacific Northwest’s largest port for most of the nineteenth-century. This was until 1890s when Seattle’s deepwater harbour was connected to the rest by rail. It provided an interior route that was not subject to the dangers of the Columbia River. One reason was that the city has its own Japantown. The timber sector gained a significant economic presence due to the large population of big leaf maple, western hemlock and Douglas fir trees.

1898 Portland waterfront

The White Eagle Saloon (circa 1910), one of many Portland establishments with alleged links to illegal activities like prostitution and gambling.

Portland was a gritty, tough port town from its inception.

Some historians believe that the city’s origins were those of a “scion from New England”; a home at the end of the earth for the exiled progeny of the eastern entrenched Aristocracy. Portland was considered one of the most dangerous ports in the world by The Oregonian in 1889. There were many saloons and bordellos in the city, along with gambling dens and boardinghouses. These places were popular among miners who came through the port after the California Gold Rush. The city’s reputation as a dangerous and violent “sober frontier” metropolis had waned by the beginning of the twentieth century.

Advancement in the 20th century

1937, Burnside Street. Between 1900 and 1930, the city’s population tripled from approximately 100,000 to 301 815.

It was home to an “assemblage facility” during WWII from which 3676 Japanese-Americans were sent into internment camps in Midwest. From May to September 10, 1942 the Pacific International Livestock Exposition processed people from the city of Seattle, Washington, and northern Oregon. General John DeWitt called the city the West Coast’s “first Jap-free” city.

In the 1940s and 1950s Portland was a major centre for organized crime and underground criminal activity.

Life magazine published a 1957 article describing the history of corruption and criminality in the city, including its gambling ring.

The story of Jim Elkins, a criminal lord, was adapted into the film Portland Expose (1957). Despite the illicit activities and seedier undercurrents, Portland enjoyed an industrial and economic boom during WWII. Henry J. Kaiser, a shipbuilder, was granted contracts to build Liberty ships and aircraft carrier transports. He had chosen construction yards in Portland, Washington. Portland’s population grew by around 150,000 over this time, mostly due to the hiring of employees.

In the 1960s, the city saw the rise of the counterculture scene in San Francisco. This was when hippie subcultures began to flourish.

The Crystal Ballroom was a central point of the city’s psychedelic cultural scene. Food cooperatives, listener-funded radio and television stations were created.

There was also a substantial presence of social activists during this time, especially in the areas Native American rights, environmental issues, and LGBT rights. Portland was a progressive city by the 1970s. The city enjoyed an economic boom throughout the decade. However, the 1979 stalling in the housing market resulted in a sharp decline in the demand for the city’s state wood industry and a significant drop in its population.

From the 1990s to the present

Portland’s technology industry grew rapidly in the 1990s, mainly due to the establishment of companies like Intel which generated over $10 billion in investment in 1995 alone.

Portland experienced a tremendous amount of growth between 2000 and 2014. It saw a population increase by more than 90% from 2000 to 2014. Portland’s growing cultural presence has made it a desirable place for young people. It was second to Louisville, Kentucky, in terms of attracting and keeping the most college-educated Americans. Portland’s GDP per capita increased by 50% between 2001-2012, more than any other American city.

The city has been called “Rose City” and “The City of Roses” throughout its history – the latter being its informal moniker since 1888, and its official title since 2003.

Another common moniker is “PDX,” which is the airport code for Portland International Airport. Bridgetown, Stumptown and Rip City are all other nicknames. P-Town; Portlandia; and the older Little Beirut.

Protests by George Floyd July 2020

Daily protests against the police killing of George Floyd began on May 28, 2020 and continued until spring 2021. The police carried out operations that led to injuries and deaths, including vandalism and looting. Local businesses suffered losses of millions of dollars due to theft and damage, according to Oregon Public Broadcasting. There were some rallies that led to clashes between law enforcement officers and protestors, which resulted both in injuries to the officers and the protestors. Federal officers were sent to guard federal property in July. Oregon politicians condemned their presence and demanded they leave. Meanwhile, lawsuits were filed against federal and local law enforcement for alleged unlawful acts.

A demonstration was held on the May 25th, 2021, one year anniversary of Floyd’s death. The demonstration caused significant property damage and led to several arrests.

Portland Geography & Geology

See also Geology of the Pacific Northwest.

Portland is located above the Boring Lava Plain. This dormant volcanic area was named after the nearby bedroom city Boring.

The Boring Lava Field, which is located in southeast Portland, has at least 32 cinder conicals, including Mount Tabor. Mount St. Helens is a volcano that is active in Washington State, 50 miles (80 km) northeast of Portland. It can be clearly seen on clear days. [70] Portland’s rocks range from the Eocene to more modern times.

A number of active, shallow fault lines cross the Portland metropolitan area.

These include both the Portland Hills Fault, located on the west side of the city, and the East Bank Fault, which is on the east side.

Because of their proximity to areas of population, some faults were deemed “possibly greater of a danger” than the Cascadia Subduction Zone in a 2017 assessment. These faults have the potential to cause magnitude 7 earthquakes. Notable earthquakes to have struck the Portland region recently include the Nisqually earthquake of 6.8 magnitude in 2001, and the March 25, 1993 earthquake of 5.6 magnitude.

A 2014 analysis found that approximately 7,000 areas in Portland are at risk of landslides or soil liquefaction if there is a major earthquake. This includes most of the city’s westside (including Washington Park) as well as parts of Clackamas County.

Portland Topography

Portland lies 60 miles (97 km) east of Oregon’s Pacific Ocean. It is near the northern end Willamette Valley. This area is Oregon’s most populated. Downtown Portland can be found on both sides the Willamette River. This river runs north through the city centre and divides the city into its east and west areas. The Columbia River is less than 10 miles (16 km) from downtown. It feeds into the Willamette River. Portland, located on the Columbia River is approximately 100 miles (160 km) upriver to the Pacific Ocean.

Although most of Portland is fairly flat, the Tualatin Mountains, also known as the “West Hills”, penetrate Portland’s northwest- and southwest sections. Council Crest Park is at 1,073 feet (327m) and is often cited as Portland’s highest point. However, it is found on the NW Skyline Blvd just north of the Willamette Stone Heritage Site. Mt. Tabor, an extinct volcano cinder cone, rises to 636 ft east of the river. It is also the highest point (194m). Rocky Butte and Powell Butte both rise to 614 feet (187 m) respectively. To the west, the Tualatin Mountains are dominated by the Oregon Coast Range. The Cascade Range is active volcanic to the east. Mt. Hood and Mt. Clear days show St. Helens dominating the horizon, while Mt. Adams and Mt. Rainier can be seen in the distance.

According to the United States Census Bureau, the city covers 145.09 sq. miles (375.78km2) in total. Of this, 133.43 sq. miles (345.58km2) are land and 11.66 sq. miles (30.20km2) are water.

Multnomah County covers almost all of Portland. However, small sections of the city can be found in Clackamas or Washington Counties with 785 and 1,455 respectively.

Portland Climate

Portland’s warm-summer Mediterranean climate is known as Koppen Csb. This climate is slightly cooler than the hot-summer Mediterranean climate of Koppen Csa. It has mild winters and dry summers.

The climate of Portland is marked by cloudy, wet, and shifting weather conditions during the autumn, winter and spring. This is due to Portland’s direct route of the stormy west flow. It also enjoys pleasant and dry summers, when the North Pacific High reaches the northernmost peak in midsummer. Portland’s USDA Plant Hardiness Zone is 8b. Some parts of Downtown fall into zone 9a.

Winters can be mild, wet, and overcast. December is the coldest month with an average daily high of 46.9 degrees F (8.3 degrees Celsius). Nightly lows are usually a few degrees higher than freezing.

The midday low temperatures drop below freezing for only 2.1 days each year. The average temperature at the lowest point is 32 degrees F (0 degrees Celsius) due to the infrequent appearance of cold waves. On December 30, 1968, 14 degrees Celsius was the lowest daytime temperature. The night temperature was 3 degrees (19 degC), on February 2, 1950. A typical window for freezing temperatures lies between November 15th and March 19 which allows for a 240-day growth period.

Portland receives an average of 4.3 inches (10.9cm) of snow annually. The majority falls between December and March.

Portland is more likely to avoid snow than its suburbs due to its low elevation and urban heat islands effect. A dusting of snow can fall outside of the downtown area, particularly at higher elevations such as the West Hills or Mount Tabor. However, downtown does not receive any accumulation. In the city’s past, there have been several major snow and ice storms. The airport saw 44.5 inches (113 cm) in 1949-50 and downtown saw 60.9 inches (155 cm in 1892-93.

Portland’s climate is perfect for rose cultivation. Image courtesy of International Rose Test Garden. Portland’s summers are hot, dry, and sunny. However, the sun is brief from mid-June through early September.

June-July, August-September account for 4.19 inches (106mm) of total precipitation. This accounts for just 11% of the 36.91in (938 in) of annual precipitation. August is the hottest month with an average temperature of 82.3 degrees F (27.9 degrees Celsius). Portland’s cool summers are protected from the moderate Pacific Ocean’s impact by its interior location at 70 miles (110km) from the coast. The Oregon Coast Range protects the west and Portland is located 70 miles (110km) away. Portland experiences heat waves only on very rare occasions. For a few days, temperatures can reach 90 degrees (32°C). On average, temperatures exceed 80 degrees Fahrenheit (27 degrees Celsius) only 61 days per year. Only 15 days reach 90 degrees (32 degC), and only 1.3 days surpass 100 degF (33.8 degC). 31 days were the highest number of 90 degree days in one year, which was in 2018.

Portland, Oregon set a record temperature of 116 degrees (47 degrees Celsius) on June 28th 2021. It also recorded the lowest temperature for a day at 75 degrees (24 degC). during 2021’s Western North America heatwave. Temperatures reached 100° Fahrenheit (38° Celsius) from May to September. Average temperatures on the hottest nights of the year are 68 degrees Fahrenheit (20° Celsius).

High-pressure ridging can send temperatures over 80 degrees (27 degrees Celsius) and cold fronts bringing daytime temperatures down to the 40s (4-9 degC). Spring and fall weather can be unpredictable. There are longer periods of cloudy skies that last from mid-fall to mid-spring. A gentle drizzle can be seen for long periods of time. This contributes to an average annual rainfall of 155 days. Temperatures reached 90 degrees (32 degrees Celsius) in April and October, respectively.
