Stormwater

  • Not only can the used motor oil can contaminate the ground water, runoff from the drain will eventually reach the river or nearby lakes and ponds and can adversely affect aquatic life.
    Stormwater
  • The soil that is carried away during a rain event ends up in the city's drainage systems and streets. Not only is this costly for the city to clean up, it can also cause our drainage system to fail. In addition, silt entering our rivers has a negative impact on aquatic life.
    Stormwater
  • The city, or EPA may fine the individual permit holder and require all work cease until the situation is addressed.
    Stormwater
  • Stormwater runoff occurs when precipitation from rain or snowmelt flows over the ground. Impervious surfaces like driveways, sidewalks, and streets prevent stormwater from naturally soaking into the ground.
    Stormwater
  • Stormwater can pick up debris, chemicals, dirt, and other pollutants and 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 water bodies we use for swimming, fishing, and providing drinking water.
