Prevent Pollution in Our Creeks and Bay

Stormwater laws prohibit any residential or industrial waste (including soapy water, dirt, paint, pool water, and landscaping run-off) from entering storm drains because they lead directly to creeks and the bay. Violators could be cited $25,000 per day. Only rain down the storm drain!
