West Seattle’s next roadside-raingarden project, officially dubbed the Delridge Natural Drainage System, is in the “early design” process. Next chance for neighbors to get updates and ask questions has just been announced – a “project-design walk-and-talk” event on Tuesday, August 12th, starting at the corner of 17th and Elmgrove (map) at 6 pm. The updates, according to this postcard that’s on its way to nearby mailboxes, will include a chance to “review proposed design concepts and plantings.” Like the county-initiated “green stormwater infrastructure” raingardens under construction in Westwood and Sunrise Heights, the goal is to reduce the stormwater going into the combined-sewer system, which in turn should reduce overflows at the end of the line. Construction is scheduled for next year.
