According to the California Employment Development Department:
Federal legislation signed into law in February 17, 2009, allows for a weekly $25 stimulus payment. This $25 stimulus payment will be added to each week of UI benefits paid to eligible workers in California. The federal legislation states that these $25 stimulus payments are only payable for weeks of unemployment that start February 22, 2009, and after.
The EDD has been continuously working to update the necessary programming to issue the $25 stimulus payments. Once the programming is completed, EDD will automatically issue payments for all eligible weeks of unemployment that start February 22, 2009, and after.
Since the $25 stimulus payments are added to your regular UI benefits, the $25 stimulus payment will not reduce your available UI claim amount.
You do not need to contact EDD to apply for the $25 stimulus payments.
