The Denny Regrades

{Belltown}

William and Sarah Bell landed at Alki Point with the Denny party in 1851. The following year they settled in today's Belltown, well north of the larger Pioneer Square settlement. Growth was slowed by the steepness of Denny Hill, which sat between the Bells' property and Pioneer Square. Population pressure after the 1897 Gold Rush forced the city northward.

Denny Hill was regraded (flattened), primarily by using hydraulic jets to sluice the soil into the bay. In 1898 the first of three regrades lowered First Avenue between Pike Street and Denny Way by 17 feet. The area west of First Avenue was not regraded, and its steep slope kept it largely industrial. The second regrade, between 1908 and 1911, leveled the land between Second and Fifth avenues, from Pine to Cedar streets.

The city regraded only the streets. Building owners had to hire their own contractors, so many pinnacles of land stood for years. The final regrading phase took place between 1928 and 1930, from Fifth Avenue east to Westlake Avenue, between Virginia and Harrison streets. The Depression halted the expected development, and much of the area remains parking lots today.
