Tree Protection in Norwalk, CA: What Residents Actually Need to Know

If you live in Norwalk or are thinking about moving there, tree protection are one of those things you probably won't think about until they affect you directly. Norwalk has 3 specific rules on the books covering different aspects of tree protection, and some of them might surprise you.
