Historical Photographs of Seattle Regrades at the Beginning of the 20th Century

Starting in 1897 and continuing through 1930, Seattle undertook a series of regrades to flatten the city’s terrain. Many of these regrades focused on the Denny Hill. City officials, including City Engineer R.H. Thompson, reasoned that Denny Hill’s steep slope prevented Seattle’s northern expansion from the business core downtown.

In 1898, the Engineering Department took the first steps to address this problem, regrading First Avenue between Pike and Denny Way. The first phase of the Denny Regrade began in 1903 and addressed the area on the western side of 5th Avenue. The first phase lasted 8 years and was completed in 1911. During this period, additional work was done to regrade Jackson Hill (in 1907) and Dearborn (1909-1912).

Between 1929 and 1930, the city completed the remainder of the regrade work on Denny Hill on the eastern side of 5th Avenue. In his autobiography, That Man Thompson, R.H. Thompson stated that over 16 million cubic yards of earth were moved as a result of the combined regrades.

The Denny Hotel (later called the Washington Hotel) stands on the south summit of Denny Hill before being torn down, 1905.

  1. So self-destruction has always been a thing in Seattle, it seems. What a vile mindset it is to wantonly destroy such beauty in the name of mere convenience.
