A King County Superior Court judge ruled Monday that the city of Des Moines and a private developer may proceed with the demolition of the Masonic Home of Washington, a more than century-old landmark at the center of a fierce preservation battle. In a ruling issued by Judge Joe Campagna, the court dismissed with prejudice a Land Use Petition Act appeal brought by Citizens for the Protection of Des Moines Historic Resources against the city and Zenith Properties LLC, the developer.
