(b) The Council shall, by act after public hearing, make any adjustment in the boundaries of election wards that is necessary as a result of population shifts and changes, not later than 90 days after the Council’s receipt of the census report, or not later than July 14th of the year in which the census report is received, whichever is later.

(c) The Council shall divide the District into 8 compact and contiguous election wards, each of which shall be approximately equal in population size.

(f) No redistricting plan or proposed amendment to a redistricting plan shall result in district populations with a deviation range more than 10% or a relative deviation greater than plus-or-minus 5%, unless the deviation results from the limitations of census geography or from the promotion of a rational public policy, including but not limited to respect for the political geography of the District, the natural geography of the District, neighborhood cohesiveness, or the development of compact and contiguous districts.

(g) No redistricting plan or proposed amendment to a redistricting plan shall be considered if the plan or amendment has the purpose and effect of diluting the voting strength of minority citizens.
