Heather Farms pool in Walnut Creek (currently a 50 meter pool and too shallow to play water polo) is scheduled to be completely torn down and remodeled into a 25 meter pool. There is a petition currently being circulated for the City of Walnut Creek to keep the pool 50 meters and make it deep enough for water polo. You do NOT need to be a resident of WC to sign the petition.
Attached is a news link and a picture of an info card with website and QR code. Just hover your phone camera over the QR code and it will take you to the page to sign the petition.
