What is Stormwater?

Stormwater starts as water from the sky. The water includes rain, snow, and hail. Once the water comes into contact with the ground it is call runoff. Once this water hits the ground it becomes contaminated with things like: dirt, fluids from automobiles, household chemicals, fertilizers, road salt, asphalt roofs, and any other debris that this water may come into contact with as it travels to the stormwater sewer.

Why is Stormwater a problem?

The problem is the contaminated stormwater runoff travels through the storm sewers directly into lakes, ponds, streams, and rivers without receiving any treatment. This affects everyone’s ability to use the water for swimming, drinking, and fishing. This contaminated stormwater runoff also affects the quality of aquatic life habitats.

Yes. St. John has Ordinance 1432 which covers Stormwater Management. Ordinance 1432 was adopted on November 16th, 2006.

I heard I can put in a rain garden and that will help with the rainwater runoff from my roof and other impervious structures. Is this true?
