The Agricultural Commissioner/Sealer of Weights and Measures submits an annual report to the Director of the California Department of Food and Agriculture on the acreage, production yields and value of agricultural products. The County of San Luis Obispo Department of Agriculture/Weights and Measures' annual Crop Report publication contains this information as well as other useful data about local agricultural production.  

The County of San Luis Obispo Department of Agriculture/Weights and Measures maintains GIS data layers which are made available to the public, other County departments and agencies for the purposes of tracking and identifying agricultural production. Information is gleaned from various Departmental processes including field visits and local knowledge of the county.

In the event of natural disasters such as severe frost, drought or excessive heat conditions occurring over a widespread area of the county causing crop damage, the Annual Crop Report and GIS data are used to develop supporting statistics to validate the degree of crop loss.  If certain criteria are met for state and federal disaster declarations, the County of San Luis Obispo Department of Agriculture/Weights and Measures will submit disaster declaration requests to the California Emergency Management Agency.
