Notwithstanding Section 53160, the legislative body of a special district may prescribe a procedure whereby duplicates of special district records less than two years old may be destroyed if they are no longer required.

For purposes of this section, video recording media, including recordings of “routine video monitoring” pursuant to Section 53160, shall be considered duplicate records if the special district keeps another record, such as written minutes or an audio recording, of the event that is recorded in the video medium. However, a video recording medium shall not be destroyed or erased pursuant to this section for at least 90 days after occurrence of the event recorded thereon.
