Stormwater Ordinance Appendices
Stormwater Management Ordinance

As stormwater flows over driveways, lawns, and sidewalks, it picks up debris, chemicals, dirt, and other pollutants. Stormwater can flow into a storm sewer system or directly to a lake, stream, river, wetland, or coastal water. Anything that enters a storm sewer system is discharged untreated into the waterbodies we use for swimming, fishing, and providing drinking water. Polluted runoff is the nation’s greatest threat to clean water. By practicing healthy household habits, homeowners can keep common pollutants like pesticides, pet waste, grass clippings, and automotive fluids off the ground and out of stormwater. Adopt these healthy household habits and help protect lakes, streams, rivers, wetlands, and coastal waters. Remember to share the habits with your neighbors!

Businesses also need to be aware that things they do or products they use in their daily operations can enter the stormwater system and affect our water sources. Runoff from construction sites, spills at fueling areas and chemicals used to keep outdoor areas clean can be picked up by rainwater and whisked into the storm sewer system. Construction Fact Sheet

Every time it rains, thousands of pounds of pet waste wash down storm drains and into streams, rivers and lakes. If not disposed of properly, pet waste flows directly into nearby streams and creeks without being treated at water treatment facilities.

When pet waste is disposed of improperly, water quality isn’t the only thing that suffers, your health may be at risk, too. Adults working in their gardens, children playing outside and pets are the most at risk for infection from some of the bacteria and parasites found in pet waste.

Flush your dog’s waste down the toilet, toss it in the trash, bury it in your yard away from vegetable gardens in several different locations; at least 12 inches deep and cover with at least eight inches of soil to let it decompose slowly or better yet, get a doggy composter.
