Now don't get me wrong, I was really excited when I spotted the first storm drain I had ever seen with TWO count 'em TWO labels on it. It was right inside the main entrance we drove each day, and right next to Reedy Creek Improvement District's office.
It turns out the 2-3 drains right by the Reedy Creek office were the only ones we saw labeled at all. This was out of seemingly thousands.
This industry needs to get over its fear of labeling storm drains in guest areas. At worse someone who does not know any better would simply scratch their heads, at best people may really dig that drains which flow immediately to a waterbody inhabited with Gods great creatures has some labeling designed to prevent an employee or guest from dumping down it.
Storm drain labelling should be required by law, not only for near water high traffic areas but for every facilitiy in the USA which has a National Pollution Discharge Elimination System (NPDES) Permit (a permit for discharging wastewater into waters of the good ol' US of A).
