Cal. Pub. Res. Code § 21092.2

The notices required pursuant to Sections 21080.4, 21083.9, 21092, 21108, and 21152 shall be mailed to every person who has filed a written request for notices with either the clerk of the governing body or, if there is no governing body, the director of the agency. If the agency offers to provide the notices by e-mail, upon filing a written request for notices, a person may request that the notices be provided to him or her by e-mail. The request may also be filed with any other person designated by the governing body or director to receive these requests. The agency may require requests for notices to be annually renewed. The public agency may charge a fee, except to other public agencies, that is reasonably related to the costs of providing this service. This section may not be construed in any manner that results in the invalidation of an action because of the failure of a person to receive a requested notice, provided that there has been substantial compliance with the requirements of this section.
