The Denny Regrade is a significant urban project in Seattle, Washington, completed in the early 20th century. It involved the removal of a steep hill, known as Denny Hill, to create a more level area for development. This regrading process began in 1895 and was completed in 1930, transforming the landscape and allowing for the expansion of the city. The project was driven by the need for more usable land as Seattle grew rapidly during the Klondike Gold Rush. The regrade not only improved accessibility but also facilitated the construction of new buildings and infrastructure, shaping the modern city we see today.
