The County of San Diego Department of Public Works (DPW), Watershed Protection Program reminds all facilities to review Best Management Practices (BMPs) in preparation for the rainy season (October 1 through April 30). BMPs prevent or reduce the discharge of pollutants to the storm drain system and waterways. Common rainy season BMPs include:

• Cleaning out storm drains and ditches
• Maintaining equipment and vehicles to prevent leaks
• Sweeping parking lots and outdoor work areas
• Covering and berming equipment and materials stored outdoors
• Updating the facility’s Storm Water Pollution Prevention Plan (SWPPP)

While implementation and maintenance of appropriate BMPs is important year-round, they become especially critical during the rainy season when storm activity increases the potential for polluted runoff to enter our storm drains and waterways.

DPW representatives may be visiting your facility to review BMPs and ensure compliance with applicable County ordinances and State stormwater regulations. Instances of non-compliance could result in the need to take stronger action, including the issuance of administrative warnings and/or citations; however, our goal is to work with you to ensure that your facility is in compliance with County ordinances and State water quality regulations without the need for stronger action. We will gladly meet with you at your facility if you have questions about these stormwater requirements.
