Agricultural and Landscape Businesses
Agricultural and landscape businesses have the potential to introduce various types of pollutants to storm water and urban runoff including maintenance of irrigation systems, pesticides, fertilizers (nutrients), landscape trimmings, soil/sediment, trash, oil, grease, and bacteria. These businesses are considered a high priority because of their ongoing outdoor operations.
The Oceanside Clean Water Program annually inspects all nursery and greenhouse operations. You can be prepared for this inspection by conducting your own internal inspection and address any concerns prior to inspector arrival. The University of California Cooperative Extension has a Self Assessment check list (154 KB) document that can be used as a guideline during your internal inspection.
The University of California Cooperative Extension also has a valuable website for agricultural businesses that focuses on Water Quality Research and Education: http://ucanr.org/sites/agwaterquality/. Here you will find online classes, slide presentations and publications to assist you in complying with runoff regulations.
The County of San Diego’s Project Clean Water website has specific BMP information for Landscape maintenance and nursery operations. Click here to go to that website.

The San Diego County Farm Bureau is a valuable resource for local growers. The San Diego Region Irrigated Lands Group is a group of growers working together to comply with clean water regulations. The program is administered by the San Diego County Farm Bureau. Regulations were recently adopted by the Regional Water Quality Control Board (See Conditional Waiver No. 4 above) requiring all agricultural and nursery operations in the San Diego region to sample and test wet and dry weather runoff for pollutants and report the findings.
The regulations allow for two options:
Conduct the testing and reporting as a group, or
Act individually to submit plans and testing results directly to the Regional Board
The San Diego County Farm Bureau is providing members with the collective testing and reporting options through the San Diego Region Irrigated Lands Group (SDRILG).
Report any water running in the street when it is not raining or someone dumping something in the storm drain or curb and gutter by calling the
Urban Runoff Hotline at 760-435-4500.
