Hi all MCSS and MCSB!
This page is filled with information, refreshers, or updates that help make your volunteer activities easy and fun. Be sure to bookmark it for important and up-to-date information to use when you are in the public, and for further reading at your leisure.
At MCSS, we focus on preventing waste, proper recycling, composting, and soil health for the city of Seattle. For services outside of Seattle, the RainWise program, gardening questions, and more, we direct people to the Garden Hotline at gardenhotline.org or (206) 633-0224.
