The lighthouse is a small but sturdy brick and stucco structure with an attached fog signal building. It remains an active navigational aid, sending out alternating red and white flashes to warn ships of potential hazards. Today, it’s a popular landmark within Discovery Park, offering visitors a glimpse into Seattle’s maritime history

From Keim:

The lighthouse, located at the water’s edge, has suffered damage from wind, rain, salt air, and saltwater. Thick paint layers trapped moisture, causing the interior paint to peel off the brick and weakening the mortar. The Portland stucco began to come apart, forming cracks that let water corrode the steel inside. Rising damp from the high-water table was also a concern. Since the federal government transferred ownership to the City of Seattle Parks and Recreation in 2004, the lighthouse has been neglected. It has now been fully restored according to the Secretary of the Interior’s Standards for the Treatment of Historic Properties. Workers stripped and cleaned the exterior, removed damaged stucco, and repaired cracks. They stabilized the brick and applied KEIM Universalputz Standard Render to level the walls, using two layers and embedding KEIM Glass Fiber Mesh in the first layer. They left space around window frames for a backer rod and KEIM Caulk. Finally, they applied KEIM Silan 100 and two coats of Soldalit ME for the white areas, and two coats of Soldalit for the green areas.
