The topography of central Seattle was radically altered by a series of regrades in the city's first century of urban settlement, in what might have been the largest such alteration of urban terrain at the time. [1]
The heart of Seattle, largest city in the state of Washington, is on an isthmus between the city's chief harbor—the saltwater Elliott Bay (an inlet of Puget Sound)—and the fresh water of Lake Washington. Capitol Hill, First Hill, and Beacon Hill collectively constitute a ridge along this isthmus (see Seven hills of Seattle). In addition, at the time the city was founded, the steep Denny Hill stood in the area now known as Belltown or the Denny Regrade.
When European settlers first came to Seattle in the early 1850s, the tides of Elliott Bay lapped at the base of Beacon Hill. [2] The original location of the settlement that became Seattle—today's Pioneer Square—was a low-lying island. A series of regrades leveled paths for roads, demolished Denny Hill, and turned much of Jackson Hill (a remnant of which remains along Main Street in the International District) into a near-canyon between First and Beacon Hills. The roughly 50,000,000 short tons (45,400,000 t) of earth from these 60 regrades [1] provided landfill for the city's waterfront and the industrial/commercial neighborhood now known as SoDo, and built Harbor Island, at the time the largest man-made island in the world. [3]
Seattle's first 58 regrades "consisted largely of cutting the tops off high places and dumping the dirt into low places and onto the beach". [4] The most dramatic result of this was along that former beach, filling the land that constitutes today's Central Waterfront. Today's Western Avenue and Alaskan Way lie on this landfill. [4]
These informal regrades came to an end around 1900; later regrades typically required changes to areas that had already undergone some development. City engineer R.H. Thomson established his prestige in 1900. He successfully provided the city with ample fresh water by running a pipeline from the Cedar River. He then undertook to level the extreme hills that rose south and north of the bustling city center. A central concern of Thomson's work in Seattle was to connect disparate parts of the city together, allowing easier movement. [5] Thomson was quoted as saying that the city had developed the land "with but little regard as to whether the streets could ever be used or not, the main idea being, apparently, to sell the lots." [5]
The first, unsuccessful, attempt to pierce the Capitol Hill – First Hill – Beacon Hill ridge came at the end of this era of informal regrades. In 1895, former territorial governor Eugene Semple (1840–1908) proposed several ambitious plans to reengineer Seattle. One of these, which he undertook in 1901, was to dig a canal from Elliott Bay to Lake Washington by cutting through Beacon Hill [6] in roughly the area of Spokane Street, [2] sluicing earth into the tide flats. His effort was defeated by unstable soils, which caused several cave-ins, and by the legal and political maneuvering of Judge Thomas Burke and others aligned with the Great Northern Railway. The Lake Washington Ship Canal ultimately followed the route north of downtown favored by Burke, [7] utilizing existing lakes and bays. [6] Semple left behind a canyon that is now used by the Spokane Street interchange on Interstate 5. [2]
Thomson resumed the work of cutting through Beacon Hill to connect central Seattle to the Rainier Valley, the first of his major regrades, [6] but he made his cut farther north. The Jackson Regrade between 1907 and 1910 slashed 85 feet (25.9 m) from the hill, [4] requiring the demolition of the public South School and the original Holy Names Academy [2] but providing fill for the tide flats below Beacon Hill that stretched south from King Street, filling in today's SoDo. Jackson Street became a slow slope upward from Elliott Bay in the west to the Central District east of the Capitol Hill – First Hill – Beacon Hill ridge. [4]
Shortly afterward, just south of the Jackson Regrade, the Dearborn Street Regrade made an even deeper cut through the ridge. In one place, the level of the land was lowered by 108 feet (32.9 m); 1.6 million cubic yards (1,223,288 m3) of earth were moved. [8] As with Semple's abandoned canal, there were several landslides, and many homes were destroyed that were not originally planned to be removed. [2] [9]
The resulting gap at Dearborn Street was deep enough to require a bridge running roughly north-south. Originally known as the 12th Avenue South Bridge and now known as the Jose P. Rizal Bridge, it is now on the National Register of Historic Places.
The Denny Regrade began before the Jackson and Dearborn Regrades, but the last stage was not completed until decades later. Before regrading, the much-admired Denny School [10] and the upmarket Washington Hotel stood atop the hill, [11] along with numerous residential buildings. [12] The two-storey high Denny School was found on Battery Street, between Fifth and Sixth Avenues, and was considered "handsome in the extreme." [13]
City engineer R.H. Thomson considered Denny Hill to be the biggest impediment to traveling to other places in the city. [14] Although in retrospect it is referred to as the Denny Regrade (and the name has become the name of a neighborhood), there were, in fact, several separate regrades of the former Denny Hill, beginning with private-sector efforts. Around 1900, property owners along relatively low-lying First Avenue took it upon themselves to cut through from Pike Street to Cedar Street. A similar cut (but initiated by the City) lowered Second Avenue in 1904; around the same time, the south part of the hill was shaved off as Pike and Pine Streets were regraded between Second and Fifth Avenues. [8]
The more dramatic Denny Regrade No. 1 (1908–1911) sluiced away the entire half of the hill closest to the waterfront, about 27 city blocks extending from Pine Street to Cedar Street and from Second to Fifth Avenues. 20,000,000 US gallons (75,708 m3) of water a day were pumped from Lake Union, to be aimed at the hill as jets of water, then run through tunnels to Elliott Bay. [8]
Much of the motivation for the regrade had been to increase land values, but the area opened up—the heart of today's Belltown—was left as a strip cut off from much of the rest of the city by the remaining eastern half of the hill, whose western face offered no route of approach. Meanwhile, property-owners and investors hesitated to build on the remaining portion of the hill, because they considered it likely that their buildings would eventually be destroyed in the next phase of the regrading process, which was now well under way. [8]
The result was Denny Regrade No. 2, begun in February 1929 and lasting 22 months. This time, the technology was power shovels rather than sluicing, with earth carried to the waterfront by conveyor belts, then placed on specially designed scows and dumped in deep water. [8] The scows were intentionally designed to capsize in a controlled manner. They were symmetrical top-to-bottom and side to side; a seacock could be opened to fill one side with water. In three minutes it would capsize, dump its load, bob up, empty the tank, and right itself. [15]
One of the buildings demolished in Denny Regrade No. 2 was the Denny School on Battery Street between 5th and 6th Avenues. Opened in 1884, it had been described as "an architectural jewel... the finest schoolhouse on the West Coast". [10]
While the 38 blocks were being regraded, the country entered the Great Depression, radically reducing the demand for land. Most of the new lots sat vacant into the 1940s; [1] the area (especially east of Sixth Avenue) remained a gray zone into the early 21st century, when it finally began to gain an urban or suburban identity as the west edge of the new growth of South Lake Union.
Thomas Burke questioned the Denny Hill regrade, stating to a reporter at the closing party of the Washington Hotel that "from a commercial point of view, and certainly from an aesthetic one, it would have been much better to have saved Denny Hill by carrying Third Avenue under it, thus obtaining the desired result, while preserving in all aspects the natural beauty that means so much to any city." [16]
Conditions were at their worst in the former Jackson and Dearborn regrade districts... In their speed to finish, contractors had left huge portions of the now-exposed hillsides barren. Rainstorms... triggered damaging mudslides that swept away homes and knocked out the Twelfth Avenue Bridge... repeatedly for the next decade.
History of Seattle, Washington 1900–1940
Belltown is the most densely populated neighborhood in Seattle, Washington, United States, located on the city's downtown waterfront on land that was artificially flattened as part of a regrading project. Formerly a low-rent, semi-industrial arts district, in recent decades it has transformed into a neighborhood of trendy restaurants, boutiques, nightclubs, and residential towers as well as warehouses and art galleries. The area is named after William Nathaniel Bell, on whose land claim the neighborhood was built.
The street layout of Seattle is based on a series of disjointed rectangular street grids. Most of Seattle and King County use a single street grid, oriented on true north. Near the center of the city, various land claims were platted in the 19th century with differently oriented grids, which still survive today. Distinctly oriented grids also exist in some cities annexed by Seattle in the early 20th century, such as Ballard and Georgetown. A small number of streets and roads are exceptions to the grid pattern.
Downtown is the central business district of Seattle, Washington. It is fairly compact compared with other city centers on the U.S. West Coast due to its geographical situation, being hemmed in on the north and east by hills, on the west by Elliott Bay, and on the south by reclaimed land that was once tidal flats. It is bounded on the north by Denny Way, beyond which are Lower Queen Anne, Seattle Center, and South Lake Union; on the east by Interstate 5, beyond which is Capitol Hill to the northeast and Central District to the east; on the south by S Dearborn Street, beyond which is Sodo; and on the west by Elliott Bay, a part of Puget Sound.
Harbor Island is an artificial island in the mouth of the Duwamish River in Seattle, Washington, US, where it empties into Elliott Bay. Built by the Puget Sound Bridge and Dredging Company, it was completed in 1909 and was then the largest artificial island in the world, at 350 acres (1.4 km2). Since 1912, the island has been used for commercial and industrial activities including secondary lead smelting, shipbuilding and repair, bulk petroleum storage, metal fabrication and containerized cargo shipping. Warehouses, laboratories and other buildings are located on the island.
West Seattle is a conglomeration of neighborhoods in Seattle, Washington, United States. It comprises two of the thirteen districts, Delridge and Southwest, and encompasses all of Seattle west of the Duwamish River. It was incorporated as an independent town in 1902 before being annexed by Seattle five years later. Among the area's attractions are its saltwater beach parks along Elliott Bay and Puget Sound, including Alki Beach Park and Lincoln Park. The area is also known for its views of the Olympic Mountains to the west and the Cascade Range to the east. One-third of Seattle's green space and urban forest is located in West Seattle, much of it in the West Duwamish Greenbelt.
The Denny Triangle is a neighborhood in Seattle, Washington, United States, that stretches north of Downtown Seattle to the grounds of Seattle Center. Its generally flat terrain was originally a steep hill, taken down as part of a mammoth construction project in the first decades of the 20th century known as the Denny Regrade, which is another name for the neighborhood on the regraded area. The name Denny Triangle, referring to the northeastern portion of this regrading project, is a term that has gained currency as this neighborhood has seen increasing development in the first decades of the 21st Century.
Queen Anne is a neighborhood and geographic feature in Seattle, Washington, United States, located northwest of downtown. Queen Anne covers an area of 7.3 square kilometers (2.8 sq mi), and has a population of about 28,000. It is bordered by Belltown to the south, Lake Union to the east, the Lake Washington Ship Canal to the north and Interbay to the west.
Interbay is a neighborhood in Seattle, Washington consisting of the valley between Queen Anne Hill on the east and Magnolia on the west, plus filled-in areas of Smith Cove and Salmon Bay. The neighborhood is bounded on the north by Salmon Bay, part of the Lake Washington Ship Canal, across which is Ballard; on the south by what remains of Smith Cove, an inlet of Elliott Bay; on the east by 15th Avenue W. and Elliott Avenue W.; and on the west by the BNSF Railway. The Ballard Bridge crosses the ship canal from Interbay to Ballard.
Denny Park is a park located in the South Lake Union neighborhood of Seattle, Washington. It occupies the block bounded by John Street and Denny Way on the north and south and Dexter and 9th Avenues N. on the west and east.
Beacon Hill is a hill and neighborhood in southeast Seattle, Washington. It is roughly bounded on the west by Interstate 5, on the north by Interstate 90, on the east by Rainier Avenue South, Cheasty Boulevard South, and Martin Luther King Junior Way South, and on the south by the Seattle city boundary. It is part of Seattle's South End.
Dr. Jose Rizal Park is a 9.6 acre park on the west slope of Beacon Hill in Seattle, Washington. The land, condemned by the city in 1917 for engineering purposes, was acquired by the Parks Department in 1971, and the park was dedicated eight years later. The park is named after José Rizal, the de facto national hero of the Philippines.
Transportation in Seattle is largely focused on the automobile like many other cities in western North America; however, the city is just old enough for its layout to reflect the age when railways and trolleys predominated. These older modes of transportation were made for a relatively well-defined downtown area and strong neighborhoods at the end of several former streetcar lines, now mostly bus lines.
Reginald Heber Thomson was a self-taught American civil engineer. He worked in Washington state, mainly in Seattle, where he became city engineer in 1892 and held the position for two decades. Alan J. Stein wrote that Thomson "probably did more than any other individual to change the face of Seattle" and was responsible for "virtually all of Seattle's infrastructure".
The Central Waterfront of Seattle, Washington, United States, is the most urbanized portion of the Elliott Bay shore. It runs from the Pioneer Square shore roughly northwest past Downtown Seattle and Belltown, ending at the Broad Street site of the Olympic Sculpture Park.
Pike Street is an east-west street in Seattle. It extends from Pike Place above Seattle's saltwater waterfront at Elliott Bay through Downtown Seattle, across Capitol Hill to the freshwater shore of Lake Washington at Lake Washington Boulevard. A segment less than a block long exists at Alaskan Way on Elliott Bay, connected to the rest of the street only by the pedestrian Pike Street Hill Climb; the bottom of the hillclimb under the Alaskan Way Viaduct was the original shoreline of the city before major modification and construction of the Seattle Seawall. It is included in the south-to-north mnemonic "Jesus Christ Made Seattle Under Protest" for the street layout of Seattle.
Denny Way is an east–west arterial street in downtown Seattle, Washington, United States. It forms the northern end of the Belltown street grid as well as the boundaries of Belltown, Lower Queen Anne, South Lake Union, Denny Triangle, and Cascade. The street continues east through Capitol Hill to Madrona as a minor neighborhood street, ending near Madrona Park on Lake Washington.
Westlake Avenue is a major street in Seattle, Washington, connecting Downtown Seattle to the neighborhoods of South Lake Union, Westlake and northeastern Queen Anne. The street runs north–south along the west side of Lake Union for 2.5 miles (4.0 km) from McGraw Square to the Fremont Bridge.
