Example of the Population Equality Requirement

Courts have allowed some deviation from exact population equality for school districts: the spread between the most- and least-populous districts should not exceed 10% of the “ideal district population” which is 1/5 of the SRUSD’s total population.

“Big picture” ideas about Trustee Areas (TAs)

    • Harden Ranch area has almost enough total population for two trustee areas
    • Santa Rita high density area’s population is a little larger than two trustee areas
    • Bolsa Knolls and surrounding area have almost enough population for one trustee area

Are there other areas, especially in the more rural parts of SRUSD, that we should identify as communities that belong together?

Harden Ranch area (numbers are Census block 2020 population totals)

7

Harden Ranch’s 2020 population of 9,638 is too little for two trustee areas,

      • It is does not make sense to add Census blocks from the northwest to Harden Ranch area because the block populations are too large
      • All parts of a trustee area must be contiguous

    • Rural part of Plan 1’s TA 5 moves to TA 4
    • TA 5 is geographically large
    • Slightly higher deviation
    • More imbalanced than Plan 1 for TAs 4 and 5, but within legal limits
