Storm Water Management

Everyday activities such as yard work and washing your car can have a detrimental impact on our water quality. Learn what you can do to help keep our water clean by using the following advice below:  

  • If you see any pollutants that have been dumped or washed down the gutters and going down the storm drains please notify the Planning and Public Works Department right away by completing the following online form. Storm Drain Pollution Complaint Form

  • Don't dump anything down storm drains. Chemicals and household products such as paint, oil, and pesticides harm fish, wildlife, and people.
  • Dispose of litter properly. Stormwater Management
  • Keep storm drains clear of debris, dirt, sand, silt, and wastes.
  • Prevent dripping and spilling automotive fluids. Used oil and filters, antifreeze, and other automotive fluids can be safely recycled at a local used oil collection center.
  • Wash cars and other vehicles at a car wash, rather than in a yard or on the street where the soap and oil will flow into a storm drain.
  • Reduce or eliminate use of chemical pesticides and fertilizers for landscaping and lawns.
  • Compost or recycle leaves and yard waste, do not dump into streams or behind fences.
  • Prevent livestock from entering watercourses by fencing and other means.
  • Clean up after pets and dispose of in trash can.
  • Take steps during construction activities to prevent dirt and sediment from running offsite and onto waterways.

This program was adopted by the Board of Supervisors on December 7, 2004.
