Tacoma City Council approved adding the North Union Avenue Greenway to the Tacoma Register of Historic Places on August 19, 2026.
Council Member John Hines praised the designation as a way to preserve neighborhood character during growth. The greenway's tree-lined medians and public space features were highlighted as unique assets that 'give neighborhoods identity.' Overwhelming community support was noted, with Hines thanking neighbors who proposed the effort.
The Historic Preservation Office and Landmarks Preservation Commission recommended the designation. No further council action is mentioned in the source, but the greenway is now officially protected under Tacoma's historic preservation policies.
