This 2004 King County decision concerns a permit application by Glacier Northwest (Northwest Aggregates) to mine and export sand and gravel from Maury Island and replace an aging barge-loading dock on Puget Sound. The project proposed replacing 228 old creosote timber piles with 62–82 steel piles, extending the dock further into the water to protect nearby eelgrass beds, and enclosing the conveyor in a steel pipe to reduce spillage and noise.

Notes
King County Department of Development and Environmental Services issued a report and decision on two shoreline permit applications (L02SH012 and L02SH013) submitted by Northwest Aggregates (Glacier Northwest) for a proposed barge-loading facility replacement on Maury Island. The project involves mining and exporting approximately 7.5 million tons of sand and gravel annually using barges, with replacement and extension of an existing dock in Puget Sound. The decision addresses mitigation measures to protect nearby eelgrass beds from shading, propeller wash, gravel spillage, and noise.
