There are a number of criteria that are required under the FAIR MAPS Act (ranked):
• Relatively equal size - people, not citizens
• Contiguous – districts should not hop/jump
• Maintain “communities of interest”
• Easily identifiable and understandable lines,
following city, natural, and man-made boundaries
• Keep districts compact – appearance/function
Ranked criteria that must be followed in city redistricting

From COI to Maps
With the FAIR MAPS Act requiring
cities to include the public input in the
redistricting process, we move
redistricting out into the public, with
maps driven by Community of Interest
testimony.
• Input from community drives process
with multiple ways for the public to
engage.
• Rules for process emphasize the
importance of traditional criteria and
minimizing divisions of neighborhoods.

Next Steps
Draft Plan Revisions
The Committee can make use of
these mapping options in a
number of ways
• Identify preferred plan(s) with an
understanding that none of these are
final plans. It is an iterative process.
• Suggest possible changes –
Redistricting Partners can provide
adjustments to the boundaries.
• Put out for public input – the public
will be very willing to tell us where we
got the lines wrong. Input is our ally in
developing final plans.
