The Fremont Neighborhood Council is hoping to gain neighborhood support to protect an 80-year-old fire station annex that may be torn down.

The annex to Fire Station 9 was built in 1921 and has been used to prepare and store oxygen tanks since the 1980s, according to a landmark nomination for the site prepared by Susan Boyle of BOLA Architecture and Planning.

The council has posted flyers around the Fremont neighborhood asking residents to write to the Landmarks Preservation Board and attend the July 1 board meeting to support the annex building, located at 3829 Linden Ave. N.

The city is looking to demolish the structure as part of a 2003 levy that created funding to replace, upgrade and renovate 32 neighborhood fire stations.

Both the annex and Fire Station 9, built in the 1950s, would be torn down and replaced.

The annex is a 2,300-square-foot concrete structure. It is stucco clad, and the raised piers at the outer corners of the parapet reflect design trends from the 1920s, according to the landmark nomination.

The Landmarks Preservation Board will review the Fire Station 9 Annex at 3:30 p.m., July 1 in Room 4060 of the Seattle Municipal Tower.
