2. Why is pet waste a problem?

Stream monitoring in Issaquah has detected elevated levels fecal coliform concentrations, exceeding state water quality standards on a regular basis during rainfall events. Fecal coliform comes from human waste, pet waste and wildlife.

Follow these pet waste tips:
• Carry a plastic bag with you on walks.

• Pet waste does not go in yard waste bin.
• Do not dispose of pet waste in native growth and vegetative areas.

3. What is a water quality violation?

By definition of the Issaquah Municipal Code, with very few exceptions, the only discharge allowed to a public or private storm system is rainwater. Water quality violations can range from minor incidents, such as car washing, to large spills from an overturned vehicle. Water quality violations can also come from multiple sources, including roadways, underground problems, failing septic systems or hazardous materials stored outside and uncovered from the rain.

4. What are prohibited discharges?
