Drainage Services                          

The LOCSD Utilities Department maintains four drainage pump stations throughout Los Osos.  They are located at the corners of Don Avenue and Mitchell Drive; 8th Street and El Moro Avenue; 16th Street and Paso Robles Avenue; and, 6th Street and El Moro Avenue.  In addition to the drainage pump stations, LOCSD crews maintain four drainage retention basins in Los Osos. The drainage retention basins are Bay Oaks and Tierra retention basins in the Bayridge Estates subdivision; Madera retention basin in Cabrillo Estates; and, Los Arboles retention basin in Vista de Oro.

Some areas in Los Osos have a history of flooding, especially during heavy rains.  The LOCSD is committed to addressing these flooding problems, working to provide information and solutions, and to promote assistance for residents impacted by storm water flows.

Sandbags are available for purchase at the LOCSD office 2122 9th Street Suite 110 during Lobby Hours only. The sandbags are sold in bundles of 10 for $5.50.  Limit of 2 bundles per resident. 

The LOCSD provides free sand on a self-service basis for sandbags at the LOCSD Utilities Water Yard at 8th Street and El Moro Avenue.  Remember to only fill sandbags half-way to 2/3.  Do not fill to top.

What is an Illicit Discharge?

Illicit discharges are generally any discharge into a storm drain system this is not composed entirely of stormwater. The exceptions include water from fire fighting activities and discharges from facilities already under an NPDES permit. Illicit discharges are a problem because, unlike wastewater which flows to a wastewater treatment plant, stormwater generally flows to waterways without any additional treatment. Illicit discharges often include pathogens, nutrients, surfactants, and various toxic pollutants.
If you see water running down the street and there are no firefighting or water operations activities going on in the immediate area, please report it to the LOCSD main office at 805-528-9370.
