Silverdale

History

Early attempts to incorporate Silverdale as a city resulted in failed ballot measures in 1941 and 1985. An incorporation referendum in November 1999 was initially defeated by a five-vote margin out of 4,000 votes cast. The election was marred by irregularities, including the inclusion of the ballot question for voters outside the proposed city boundaries and exclusion for voters inside the proposed boundaries. A re-vote was held on February 1, 2000, and rejected by a wider margin.
