Benchmarks: December 10, 1930: Seattle’s Denny Hill disappears

Few cities in the United States can rival Seattle for the scale of reengineering to its landscape. Not only did its citizens make more than 890 hectares of new land in its harbor, but they also replumbed the city’s largest lake, completely changing its drainage pattern and drying up its main outlet, and regraded tens of millions of cubic meters of its hills. The most famous of these projects was the elimination of Denny Hill, a 73-meter-high hill that stood at the north end of Seattle’s central business district.

Public improvements, private funding

Seattle city engineer Reginald H. Thomson may have been the driving force behind the Denny Hill regrades, but they could not have occurred without public support. In order for a regrade to proceed, at least 50 percent of the people who lived in the affected areas had to sign a petition. For example, the Second Avenue regrade needed the signatures of 67 property owners. A completed petition triggered the next phase, which was a city council ordinance that defined the boundaries of the regrade. A second ordinance then provided the funding mechanism, or what was known as a Local Improvement District (LID).
