Drainage System Maintenance

The County of San Diego has a complex storm drainage system composed of streets and gutters, catch basins, underground pipes, ditches, pump stations, and channels. This system is used to carry water away from homes and businesses into rivers and streams. It is important to consistently maintain this system so it can be used to full capacity. The County of San Diego regularly inspects the system and performs maintenance as needed. Please help us ensure the capacity of this system.

  • Keep streams and other conveyances that carry rainfall runoff through your property free of obstructions and debris such as trees, tall bushes, and trash. A plugged or obstructed drain cannot carry water and could cause flooding. Never dump or throw anything into the streets or storm-drainage system. To do so is a violation of the County of San Diego’s Storm Water Quality Management Ordinance No. 8394.

  • If you see trash or debris in the storm drainage system, contact the County Department of Public Works Field Operations staff at (619) 443-1260 weekdays or (858) 565-5262 evenings and weekends.

If you have questions or would like additional information,
