(a) Following each federal decennial census, and using that census as a basis, the council shall, by ordinance or resolution, adopt boundaries for all of the council districts of the city so that the council districts shall be substantially equal in population as required by the United States Constitution.

(1) Population equality shall be based on the total population of residents of the city as determined by the census.

(2) Notwithstanding paragraph (1), an incarcerated person, as that term is used in Section 21003, shall not be counted towards a city’s population, except for an incarcerated person whose last known place of residence may be assigned to a census block in the city, if information about the last known place of residence for incarcerated persons is included in the computerized database for redistricting that is developed in accordance with subdivision (b) of Section 8253 of the Government Code, and that database is made publicly available.

(b) The council shall adopt council district boundaries that comply with the United States Constitution, the California Constitution, and the federal Voting Rights Act of 1965 (52 U.S.C. Sec. 10301 et seq.).

(c) The council shall adopt district boundaries using the following criteria as set forth in the following order of priority:

(1) To the extent practicable, council districts shall be geographically contiguous. Areas that meet only at the points of adjoining corners are not contiguous. Areas that are separated by water and not connected by a bridge, tunnel, or regular ferry service are not contiguous.

(2) To the extent practicable, the geographic integrity of any local neighborhood or local community of interest shall be respected in a manner that minimizes its division. A “community of interest” is a population that shares common social or economic interests that should be included within a single district for purposes of its effective and fair representation. Communities of interest do not include relationships with political parties, incumbents, or political candidates.

(3) Council district boundaries should be easily identifiable and understandable by residents. To the extent practicable, council districts shall be bounded by natural and artificial barriers, by streets, or by the boundaries of the city.

(4) To the extent practicable, and where it does not conflict with the preceding criteria in this subdivision, council districts shall be drawn to encourage geographical compactness in a manner that nearby areas of population are not bypassed in favor of more distant populations.

(d) The council shall not adopt council district boundaries for the purpose of favoring or discriminating against a political party.
