"I am a resident of Discovery Bay. As a whole, this little town is pretty safe. Very pet friendly. Great elementary schools and churches. Most within walking distance. Caution is required when crossing in the crosswalks at Discovery Bay Blvd. and Riverlake Rd's. as there has been a few minor hit and runs. Discovery Bay is a friendly community and a great place to raise your children."
