On January 6, 1899, the first phase of the massive Denny Regrade is completed. The regrade of Denny Hill is one of several projects designed to make more level the steep hills of Seattle.

The Denny Regrade was started in 1898 to level 1st Avenue from Pine Street to Denny Way (just north of downtown Seattle). Excess dirt was dumped into the tidelands of Elliott Bay near Railroad Avenue (later renamed Alaska Way) and Western Avenue.

The contract for the second phase of the Denny Hill regrade, located between 2nd Avenue and 5th Avenue, was issued on August 29, 1903.
