CA Fish & Game Code Section 2074.4

If a petition is accepted by the commission for consideration, all reasonable attempts shall be made to notify affected and interested parties and to solicit data and comments on the petitioned action from as many persons as is practicable. In addition to commission efforts to provide notification through distribution of the commission agenda and minutes pursuant to Section 2078, the department shall immediately undertake efforts to notify affected and interested parties. Methods of notification may include, but are not limited to, correspondence, newspaper notices, and press releases, and notification shall include notice to owners of that land which may provide habitat essential to the continued existence of the species, unless the director determines that ownership is so widespread, fragmented, or complex as to make individual notice impractical.
