Hi Deborah,
You may have this info. already, but I highly recommend connecting with Sharon Gamson Danks, who is an environmental planner and a Principal of Bay Tree Design, inc. in Berkeley, CA, and author of the recent book Asphalt to Ecosystems: Design Ideas for Schoolyard Transformation (New Village Press) – She is an expert on ecological schoolyard design at all levels, and her knowledge of the local school district systems may be particularly helpful to you since she is based in the Bay Area.
Good luck!
– Liz
