Storm Water Program

Storm Water Program

 Storm Drain Did you know that dumping into the gutter or storm drain is illegal and can result in fines or penalties?

Motor oil, paint products, chemicals, litter and other pollutants can contaminate local waterways and threaten wildlife when they are illegally dumped into storm drains.

The Environmental Services Section responds to reports of illegal dumping into storm drains by individuals and businesses. The section also monitors and enforces federal, state and local water quality laws and regulations by regularly inspecting local industrial facilities to ensure that they comply with water quality regulations.
