Storm Water Runoff

Provides Signage Adjacent to Storm Drain Inlet to Discourage Illegal Dumping of Pollutants. (City of Santa Barbara)

Storm water runoff is rainfall that washes over the surface of the land picking up pollutants as it travels. Storm water runoff may collect and transport soil particles, petroleum products, waste, litter and debris to adjacent waterways. These pollutants are generally found to degrade water quality.

While marina and yacht club waters are often contaminated with storm water pollutants from non-marina or yacht club and boating sources (upland sources), these pollutants may also be discharged by the marina or yacht club itself as a result of vehicular traffic equipment operation lawn care and landscaping, and shore-side boat maintenance activities. Toxic materials from paint chips and sanding debris, as well as oil and grease from boat maintenance yards and parking lots wash into marinas and yacht clubs from storm water.

Marina and Yacht Club Best Management Practices

  1. Develop a Storm Water Pollution Prevention Plan where applicable.
  2. Maintain materials and equipment such as booms and absorbent pads needed for a storm water spill response and ensure they are readily available.
  3. Marinas and yacht clubs should annually conduct a storm water pollution prevention training that focuses on employee responsibility for creating, managing and updating the Best Management Practices that prevent storm water pollution. This training should discuss good housekeeping, preventive maintenance, spill prevention and response and material management practices.
  4. Report spills that enter or have potential to enter the storm drain system or a water body to your local authorities including the Regional Water Board and the Department of Fish and Game (800-852-7550 OES).
  5. Provide signage adjacent to storm drain inlet and any permeable areas to discourage illegal dumping of pollutants.
  6. Prohibit vehicle and vessel maintenance in marina or yacht club parking lots.
  7. Prohibit vehicle or vessel washing in marina or yacht club parking lots.
  8. Provide signs adjacent to parking lots that prohibit littering, dumping and/or vehicle or vessel servicing/cleaning.
  9. Develop and implement regular sweeping/cleaning program.
  10. Reduce or eliminate landscaping and irrigation runoff into the storm drain or water body. This can be done by providing landscape swales, permeable pavement, buffer strips, rain gardens or other treatment alternatives, to filter pollutant runoff from impervious surfaces such as parking lots and roof tops. Protect existing permeable areas and incorporate permeable pavement where feasible for new and redevelopment projects.
  11. Avoid landscaping and/or practices of over watering or over fertilizing or having loose soils that may cause pollutant runoff to enter storm drains or water bodies.
  12. Boaters should be encouraged to use the least toxic products.
