Didn’t get a chance to join in the National Day of Service today? Or – you did, but you’re still ready to do more? This weekend, you are invited to join in a major cleanup along Delridge — the North Delridge Neighborhood Council is teaming with the Chief Sealth High School Parents-Teachers-Students Association (PTSA). Just show up at Delridge Community Center (map) or the Chief Sealth parking lot (at Boren; map) between 9:45 and 10 am Saturday to get supplies (plus coffee and muffins); they’re hoping for enough help to clean up Delridge from Andover all the way to Sylvan Way (see map above). Part of the plan is to clear storm drains along the way, to prevent flooding next time it rains. Students can get community-service credit, too. Here’s the official flyer, with e-mail addresses if you have questions for an organizer.
