Stormwater Quality

The Storm Drainage System does not include any treatment system. So, any litter, sediment or pollution on the ground has a potential of getting washed into the storm drain and into our rivers.

  • Keep It Clean Cause We're All Downstream-Learn how you can "Keep It Clean" and reduce water pollution
  • Construction Activity Permits- Stormwater discharges from construction sites and grading are covered under the Construction Activity Permits.  If a Construction Permit is required, it must be obtained prior to any on-site construction activity. 
  • Storm Drainage
  • Prohibited Discharges- The storm drainage system is designed to accept only storm water and snow melt. But, pollution has the ability to enter storm drains, too.
