“Delta” means the Sacramento-San Joaquin Delta, as defined in Section 12220 of the Water Code, for all provisions of this division, other than Chapter 3 (commencing with Section 29735). For the purposes of Chapter 3 (commencing with Section 29735), “delta” means the area of the delta minus the area contained in Alameda County.
The legislature occasionally skips outline levels.
(3) A person may apply [...]
(4)(a) A person petitioning for relief [...]
In this example, (3), (4),
and (4)(a) are all outline levels, but
omitted by its authors. It's only implied. This presents an
interesting challenge when laying out the text. We've
decided to display a blank section with this note, in order
to aide readability.
