Utah Avenue S

Like Colorado Avenue S, this street was created in 1895 as part of the plat of Seattle’s tide lands. As I wrote in that post,

As Seattle expanded to the south, it became obvious that Commercial Street (1st Avenue S) would not be the westernmost street east of Elliott Bay. Fortunately, instead of using zero or negative numbers, they went with states: the first street west of 1st was named Utah, and the next, Colorado. (Some perpendicular streets were named Alaska, Vermont, Connecticut, Texas, Massachusetts, etc. There doesn’t appear to have been any particular order.)

Utah Avenue S begins at S Atlantic Street and goes 1⅐ miles south to S Hinds Street, the block between S Stacy Street and S Lander Street, in front of the Starbucks Center, being closed to motorized traffic. There is another short segment between Denver Avenue S and S Alaska Street, and a final one that stretches ⅓ of a mile from S Hudson Street to S Findlay Street.

The most famous structure on Utah Avenue S was built between 1912 and 1915 as the West Coast catalog distribution center for Sears, Roebuck and Company. It was once the largest building west of the Mississippi River. This photograph was taken in May 1918.

High Point Drive SW

This street was named after High Point, originally developed by the Seattle Housing Authority in 1942 as defense housing and redeveloped in 2004 (see SW Bataan Street and Lanham Place SW for more history). I appear not to have mentioned in either of those posts why the development was so named — as one might guess, the city’s highest point (520 feet) is there, at the corner of 35th Avenue SW and SW Myrtle Street.

High Point Drive SW begins at 30th Avenue SW and SW Juneau Street and goes nearly ⅔ of a mile south to Sylvan Way SW and SW Holly Street.

Arboretum Drive E

This street in the Washington Park Arboretum was, like E Foster Island Road, originally unnamed. It received its current name in June 1957. The Arboretum itself was established in 1934 on the western half of a tract that had been logged by the Puget Mill Company; the eastern half became the gated Broadmoor neighborhood and golf course (see Broadmoor Drive E).

The street, which begins at Lake Washington Boulevard E opposite the Washington Park Playfield, goes nearly a mile north to E Foster Island Road just west of the north entrance to Broadmoor. All but the very northernmost portion, which leads to the Graham Visitors Center, has been closed to motorized traffic for over a decade.

Duwamish Avenue S

This street was created in 1895 as part of the Seattle Tide Lands plat. As I wrote in S Spokane Street, “Streets in this plat that were not extensions of already existing ones, such as Commercial Street, were named after letters of the alphabet, American cities, American states, prominent local politicians, and places in Washington”; these last included Chelan, Duwamish, Kitsap, Klickitat, Queets, Quilcene, Quileute, Quinault, Spokane, Vashon, Wenatchee, and Whatcom, the ones in italics still existing today. It seems strange to me that the Duwamish name would have been applied to such a short street, it being the name of Seattle’s principal river (dxwdəw) and indigenous inhabitants, the Duwamish Tribe (dxʷdəwʔabš), but there you have it. At least it still exists.

In “Elliott Way” just a placeholder name, I quote an email I wrote to the Seattle City Council and the Waterfront Seattle Program in December 2020 which read, in part, “I urge you… to name [Elliott Way] something else. The Duwamish people, for example, have Duwamish Avenue S named for them (actually more likely for the river…), but it is an insignificant street 2/10 of a mile long hidden under the Spokane Street Viaduct and the Alaskan Freeway. Perhaps Duwamish Avenue would be a better choice, if the tribe approved?” I still think this would be a good idea (and it would give us another naming opportunity as well). They did respond favorably, said they had been thinking along the same lines, and as of January 2022 “continue to coordinate with the tribes and other partners on a proposed name.” I hope they come up with something soon, as what is still being referred to as Elliott Way is due to open by year’s end!

As I mentioned in my email, Duwamish Avenue S is 2/10 of a mile long, beginning at E Marginal Way S and ending at a Port of Seattle road just south of the West Seattle and Spokane Street Bridges.

Update as of February 2, 2023: I posted an article last month  “Dzidzilalich” to be honorary name for Elliott Way, Alaskan Way — noting that, in fact, the roadway will be known as Elliott Way… but will carry the honorary name “Dzidzilalich.” So it seems “Elliott Way,” after all, is unfortunately not just a placeholder name, and for now the Duwamish name remains confined to this obscure thousand-foot-long street.

Portion of 1895 plat of Seattle Tide Lands showing Duwamish Avenue, as platted from Spokane Avenue (now Street) in the northwest to Seattle Boulevard in the southeast. The visible portion of Seattle Boulevard is now Diagonal Avenue S, Whatcom Avenue is now E Marginal Way S, and Grant Street is now Airport Way S.

Lincoln Park Way SW

This street was named for Lincoln Park, which occupies Williams Point in West Seattle. Originally called Williams Point Park in the Olmsted Brothers’ 1908 report to the city, the 135-acre park was intended to be named Fauntleroy Park. However, when it opened in 1922, it was decided to name it after President Abraham Lincoln (1809–1865) instead, according to Seattle parks historian Don Sherwood. This required that Lincoln Beach, just to the north, be renamed Lowman Beach, and that Lincoln Park Playfield on Capitol Hill (named for the adjacent Lincoln Reservoir) be renamed Broadway Playfield. (Today, the entire tract is known as Cal Anderson Park, which contains the reservoir and the once-again-renamed Bobby Morris Playfield. A Fauntleroy Park was finally established in the early 1970s.)

Lincoln Park Way SW begins at Beach Drive SW and 48th Avenue SW and goes ¼ of a mile southeast to 47th Avenue SW between SW Myrtle Street and SW Othello Street. The park begins 500 feet to the south, at the corner of 47th Avenue SW and SW Fontanelle Street.

Coniston Road NE

This street in Seattle’s Windermere neighborhood runs around 350 feet on either side of NE Windermere Road (so 700 feet total) just southeast of the neighborhood’s main entrance off Sand Point Way NE. It appears to have been named either after the Lake District village of Coniston, in the county of Cumbria, England, or Coniston Water, England’s fifth largest natural lake. Coniston is about 4⅔ miles west of Windermere, England’s largest natural lake, after which the neighborhood was named.

NE Penrith Road

This street in Seattle’s Windermere neighborhood runs just over ⅕ of a mile from Kenilworth Place NE in the west to NE Ambleside Road in the east. It appears to have been named after the Lake District town of Penrith, in the county of Cumbria, England. Penrith is about 18¾ miles northeast of Windermere, England’s largest natural lake, after which the neighborhood was named.

NE Keswick Drive

This street in Seattle’s Windermere neighborhood runs just over ⅓ of a mile from NE Windermere Road and Elleray Lane NE in the southwest to 64th Avenue NE in the northeast. It appears to have been named after the Lake District town of Keswick, in the county of Cumbria, England. Just north of Derwentwater, Keswick is about 13¾ miles northwest of Windermere, England’s largest natural lake, after which the neighborhood was named.

NE Ambleside Road

This street in Seattle’s Windermere neighborhood runs just under 900 feet from the private Windermere Park in the southwest to NE Windermere Road in the northeast. It appears to have been named after the town of Ambleside, in the county of Cumbria, England. As Wikipedia notes, Ambleside “marks the head (and sits on the east side of the northern headwater) of Windermere, England’s largest natural lake.”

Arapahoe Place W

This street was created in 1890 as part of the plat of the Bluff Park Addition to the City of Seattle, filed by Avery Parker of Arapahoe County, Colorado. Originally Arapahoe Avenue, it appears to have been named after that county, whose seat at the time was Denver. (The city was split off from the rest of the county in 1902.) Arapahoe County was itself named in 1861 for the Arapaho, a Native American people whose territory once included the area, but were subsequently forced onto reservations in Wyoming and Oklahoma.

Today, Arapahoe Place W begins at W Dravus Street and goes 450 feet north to just beyond W Prosper Street. It then resumes half a block north at W Bertona Street and goes ¼ mile north to W Emerson Street, along the south edge of Discovery Park.

Padilla Place S

This street was created in 1889 as part of the Commercial Street Steam Motor Addition to the City of Seattle. It appears to have been named for Padilla Bay, which lies between Guemes and Fidalgo Islands and the mainland and is about 60 miles northwest of Seattle, as S Orcas Street appears to honor Orcas Island and S Fidalgo Street, Fidalgo Island. Like Orcas Island, it was named after Juan Vicente de Güemes Padilla Horcasitas y Aguayo, 2nd Count of Revillagigedo, Viceroy of New Spain, who sent an expedition to explore the area in the early 1790s.

Padilla Place S begins at S Homer Street and goes two blocks southwest to S Fidalgo Street, crossing S Orcas Street on the way.

S Fidalgo Street

This street was created in 1889 as part of the Commercial Street Steam Motor Addition to the City of Seattle. It appears to have been named for Fidalgo Island in Skagit County, which is about 60 miles to the northwest, as S Orcas Street appears to honor Orcas Island and Padilla Place S, Padilla Bay. The island itself was named after Salvador Fidalgo y Lopegarcía, who explored the area for the Spanish in the early 1790s.

S Fidalgo Street begins at a shoreline street end on the Duwamish Waterway just west of Ohio Avenue S and goes 700 feet east to E Marginal Way S. It picks up again at 1st Avenue S and goes half a mile east, then southeast, to a dead end just east of Padilla Place S.

S Orcas Street

This street was created in 1889 as part of the Commercial Street Steam Motor Addition to the City of Seattle. It appears to have been named for Orcas Island, largest of the San Juan Islands, which is about 75 miles to the northwest, as S Fidalgo Street appears to honor Fidalgo Island and Padilla Place S, Padilla Bay. The island’s name, per Wikipedia, derives from that of “Juan Vicente de Güemes Padilla Horcasitas y Aguayo, 2nd Count of Revillagigedo, the Viceroy of New Spain who sent an exploration expedition under Francisco de Eliza to the Pacific Northwest in 1791.” Eliza named the surrounding area Horcasitas, but in 1847 the British, who maintained their claim on the San Juans until 1871, assigned a shortened version — Orcas — specifically to the island. (It is a coincidence that Orcas Island is an excellent location for watching orca whales; the two names are completely unrelated.)

S Orcas Street begins at E Marginal Way S and goes ¾ of a mile east, then southeast, to Corson Avenue S, where it becomes S Doris Street. It picks up again east of Interstate 5 at 15th Avenue S and goes three blocks east to 18th Avenue S. Its longest and final stretch begins just west of 20th Avenue S and goes 2¼ miles east to Lake Washington Boulevard S just west of Seward Park.

Seward Park Road

This road is named after Seward Park, which occupies all of Bailey Peninsula’s 300 acres, as envisioned by the Olmsted Brothers. The park itself was bought by the city in 1911 and named after William Henry Seward (1801–1872), who was governor of New York from 1839–1842, senator from New York from 1849–1861, and secretary of state under Abraham Lincoln and Andrew Johnson from 1861–1869. His negotiation of the purchase of Alaska from Russia in 1867 proved to be a major boon for Seattle, which nearly doubled its population between 1890 and 1900 due in no small part to the Klondike Gold Rush, and remains a gateway to Alaska to this day.

Seward Park Road begins at Lake Washington Boulevard S and S Juneau Street and winds for ⅓ of a mile into the park’s interior, where it becomes a ¾-mile-long loop. (It should not be confused with Shore Loop Road, which runs along the park’s perimeter on the Lake Washington shoreline and is not open to vehicle traffic. Like all park roads in Seattle, Seward Park Road carries no directional designation)

Article in June 11, 1911, Seattle Times on naming of Seward Park
Article in The Seattle Times on the naming of Seward Park, June 11, 1911. William Elder Bailey paid $26,000 to buy Bailey Peninsula in 1889 and the city began to consider it a potential park shortly thereafter. (It had previously been known as Graham Peninsula, after early settler David Graham, and Andrews Peninsula [though no one is sure who this Andrews might have been].) Bailey made it difficult for the city, finally offering to sell it for $430,000 in 1908, but the city ended up acquiring it for a more reasonable $322,000 in early 1911.

Cowen Place NE

This street was created as part of the 1906 plat of Cowen’s University Park, filed by the Sylvester-Cowen Investment Company, of which Charles Cowen (1869–1926) was president. Originally Ravenna Place, it received its current name in 1918, according to an article in the January 29 issue of The Seattle Times. (This article also reported that the names of the individual streets that made up Queen Anne Boulevard would be restored and that Oriental Avenue [counterpart of the still-existing Occidental Avenue S] would become Third Avenue S). Whether it honors Cowen or the park named after him, which he donated to the city in 1906, is unclear.

Cowen was born in England, moved with his family to South Africa, and came to the United States in 1890, arriving in Seattle in 1900. Dotty DeCoster writes for HistoryLink.org:

Cowen was, by many accounts, a lively and active participant in developing the University District. According to architectural historian Shirley L. Courtois, he was British and had grown up in South Africa, where his family members were diamond miners and merchants. In 1890 he was sent to New York to purchase equipment for the mines. He never returned to South Africa. He apparently broke with his family, changed his name from Cohen to Cowen, and settled first in New York State, then in Florida, and finally in Seattle. Cowen reportedly retained a distinctively English style throughout his life.

The facts that his surname was originally Cohen and that his family was involved in diamond mining in South Africa led me to think he must have been Jewish, but I could find no definitive mention of his ethnicity online. However, in the March 19, 1926, issue of The Seattle Times, I found an article on the probate of his will, which mentioned that $2,000 of his $50,000 estate would go to the Hebrew Benevolent Society (today known as Jewish Family Service). That makes Cowen and Henry Fuhrman (1844–1907) (Fuhrman Avenue E) the only Jews I am aware of who have Seattle streets named after them. (Note added November 9, 2024: Now there’s a third: Sue Bird [born 1980] [Sue Bird Court N]).

Cowen Place NE begins at NE Ravenna Boulevard and University Way NE and goes just over 325 feet northeast to 15th Avenue NE, at the south end of the Cowen Park Bridge.

Fauntlee Crest SW

This street was created in 1955 as 43rd Avenue SW in the plat of Fauntlee Hills Division № 5. It received its current name in 1959. “Faunt” is an obvious reference to the greater Fauntleroy neighborhood, and Fauntlee Hills was developed on the western slope of the hill that rose up from Fauntleroy Cove, but I’m not sure where “lee” comes from. (I was thinking, perhaps, from “leeward,” but prevailing winds in Seattle are from the southwest, meaning this is the windward, not leeward, side of the hill. Perhaps Arthur C. Webb, the developer, simply thought it sounded euphonious.)

Like its neighbor Vashon View SW (which was originally named Fauntlee Place SW!), this appears to be the only crest in the city. (The USPS abbreviates these as CRST, while its Seattle street sign abbreviation is Cr.)

Fauntlee Crest SW begins at SW Concord Street and California Avenue SW and goes ¼ mile north to a dead end.

Rainier Avenue S

This street follows the route of the Rainier Avenue Electric Railway Company’s Seattle-to-Renton line, which began to be built in 1891. Both the rail line and street were named for Mount Rainier (təqʷubəʔ), itself named by Captain George Vancouver for his friend, Royal Navy Rear Admiral Peter Rainier (1741–1808). As the Seattle Post-Intelligencer noted on September 3, 1890, “the avenue points straight toward Mount Rainier, which mountain will be in plain view all the way.”

Rainier Avenue S begins at the intersection of S Jackson Street, Boren Avenue S, and 14th Avenue S, and goes nearly 8 miles southeast to the city limits. From there, it continues around 3¾ miles south to the intersection of Interstate 405 and State Route 167 in Renton.

NW Carkeek Park Road

This street was named for Carkeek Park, which encompasses 216 acres in the Broadview neighborhood, including Pipers Creek and nearly ½ a mile of Puget Sound waterfront (though the usable beach is much shorter, as the main line of the BNSF Railway cuts off public access to the rest). It was one of the “46 new street names to simplify street addresses” The Seattle Times reported on in its issue November 6, 1960, and was made up of “Sixth Avenue Northwest from West 110th to West 111th Streets, West 111th Street from Sixth to Seventh Avenues Northwest, Seventh Avenue NW from West 111th to West 114th Streets, and West 114th Street from Seventh Avenue NW to West 116th Street.” (Part of this route was once Puget Drive, part of the 1911 View-Lands Addition.)

The park itself opened in 1929 and was named for Morgan James Carkeek (1847–1931) and his wife, Emily Gaskill Carkeek (1852–1926). According to the Museum of History & Industry, “Morgan… was an accomplished stonemason and successful building contractor who built several of Seattle’s early stone buildings, such as the Dexter Horton Bank, and large office buildings, including the Burke and Haller buildings.” In 1918, he and Emily donated land to the city for the first Carkeek Park, located along Lake Washington where Magnuson Park is today, but soon thereafter plans were made to develop Naval Air Station Seattle on the land, and the park was taken over by the Navy in 1926. The Carkeeks donated $25,000 to the city to purchase land elsewhere, and with the addition of $100,000 in public funds the city was able to buy Piper’s Canyon.

Report in The Seattle Times, May 28, 1927, on the Carkeeks’ contribution of funds to buy Piper’s Canyon. The Seattle Historical Society, which they had a hand in founding, never did build a museum in Carkeek Park, but ended up building the Museum of History & Industry in Montlake’s McCurdy Park instead. MOHAI opened in 1952 and moved to Lake Union Park in 2012 after having to make way for the expansion of Washington State Route 520.

NW Carkeek Park Road begins at NW 110th Street and Puget Drive NW and winds ½ a mile northwest to the entrance to Carkeek Park at NW 114th Street. Within the park, it goes a further ½ mile west, ending at a parking lot, picnic area, and playground. (This portion appears to have once been known as Piper’s Canyon Road or Pipers Road.) From here, there is a bridge over the BNSF Railway tracks to a beach along Puget Sound and the mouth of Pipers Creek.

Seola Beach Drive SW

According to Seattle parks historian Don Sherwood’s sheet on Seola Park, this street began as a logging railroad. It was then replaced by the Charles Arey county road (“recently surveyed,” according to an article in the August 26, 1893, Seattle Post-Intelligencer), which was renamed Qualheim Road in 1914 by Carl Olsen Qualheim. It received its current name in 1956 when that portion of Arbor Heights was annexed to Seattle. “Seola” itself was the product of a naming contest:

In 1893, a family named Kakeldy built the first home on the beach.… Before long, children in the vicinity school referred to residents of Kakeldy Beach as the “Cackilty Chickens.”… In 1910 the beach residents sponsored a renaming contest which was won by Mel Miller, friend of the school’s teacher of Spanish, Agnes Quigley; his suggestion: “Se-ola = to know the wave.”

Seola Beach Drive SW begins at SW 106th Street between 28th Avenue SW and 31st Avenue SW and goes ⅞ of a mile south, then southwest, to a dead end at the beach, just past SW Seola Lane.

For its entire length, Seola Beach Drive SW forms the southern city limits of Seattle, separating it from Burien and unincorporated King County (White Center). (Unlike the northern city limits, formed by 145th Street, Seattle’s southern city limits are jagged. If they went due east from Seola Beach, Seattle would encompass large portions of Burien, Tukwila, and Renton; whereas if they followed a parallel set at the city limits’ northernmost point, everything south of Kenyon Street [approximately the north end of the South Park Bridge] would be lost to Seattle.)

Frater Avenue SW

I first came across the Alki History Project while doing research for my article on SW Bronson Way. I’m not sure how I missed it before. The paper that mentioned Ira Bronson was “If at First You Don’t Succeed…,” a fascinating history of municipal governance and elections in West Seattle, and when I looked at their list of other papers I was thrilled to see among them “What’s in a Name?” — an investigation of Alki street names, both current and those changed long ago. Frater Avenue SW is the first of a number of posts in which I will be citing this paper, written by Phillip H. Hoffman, director of the project.

Frater Avenue SW originates in the 1955 plat of Anderson’s Soundview Terrace Addition № 2. Why Anderson, Caple, or Knowlton weren’t chosen instead for the honor (this being the only new street in the small subdivision, and those being the surnames of the three couples who filed the plat) isn’t clear. But, as Hoffman notes, SW Frater Street and SW Frater Place (both of which have since been vacated) were just to the west in the adjacent plat. In addition, an earlier Frater Avenue SW had existed, until it was vacated in 1942, just southeast of where today’s Frater Avenue begins at SW Spokane Street. The current Frater Avenue must have been named after one of these three streets.

But, of course, that leaves the question of who those three streets initially honored, and according to Hoffman,

Frater Avenue first appears in the plat Partition of Crawford Tract as ordered in King County Superior Court, Cause № 64110, June 17, 1915. [A.W.] Frater was the presiding judge.… The court commissioners assisting in the adjudication of a land title and ownership dispute before Judge Frater that resulted in the Crawford Tract plat probably named Frater Avenue in 1915, along with all the other streets appearing in the plat.

Archibald Wanless Frater (1856–1925), according to Cornelius Holgate in Seattle and Environs, was born in Ohio and came to Washington in 1888. Initially settling in Tacoma, he moved to Snohomish the next year and came to Seattle in 1898.

Today’s Frater Avenue SW begins at 57th Avenue SW just north of SW Hinds Street and goes ⅛ of a mile southeast to SW Spokane Street just west of 56th Avenue SW.
