Business Pollution Prevention

The City of Kirkland inspects businesses and works with them to prevent pollutants from entering private and public storm drains, which eventually discharge to our streams, lakes and wetlands. Kirkland City Code (KMC 15.52.090-110) requires that businesses implement source control best management practices (BMP’s), as described in Department of Ecology's Volume IV of the 2005 Stormwater Management Manual for Western Washingtonexternal link icon

Best Management Practices
Source control best management practices are things you can do at your business to prevent rainwater from coming into contact with pollutants. Best management practices includes things like covering a pile of exposed soil to prevent erosion, fixing leaking garbage dumpster or compactors, and having a spill kit on hand to deal with leaks and spills. Please refer to the Business Pollution Prevention Guide (PDF) for further information.

Business Inspection Process
During a site visit the inspector will do the following:

  • Talk with the site manager or owner and gather information about what types of activities occur at the site.
  • Walk the site with the property representative and make observations about what best management practices may already be in place and which ones are still needed.
  • Provide onsite technical assistance regarding the best management practices that may need to be implemented.
  • Leave the property representative with information on the necessary corrective actions and/or follow up with a corrective action letter.
