City of Santa Rosa
2021-22 Redistricting
March 29, 2022
California Fair Maps Act
The Fair Maps Act passed by the Legislature mandates a
set of criteria we must follow when drawing district plans. • Relatively equal size - people, not citizens
• Contiguous – districts should not hop/jump
• Maintain “communities of interest”
• Follow city and census designated place boundaries
• Keep districts compact – appearance/function
Open and Fair redistricting process
From COI to Maps
With more cities and counties using
community-based redistricting, 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.
• Releasing maps for feedback – today we
will see plans to spark more public
engagement.

Maps to Review
Plan to review:
• Plan A2
An overview, data table, individual
district pages and web map that
has been provided to the district
and is available on the city
redistricting website.
The total deviation of the plan is the sum of
the absolute values of the highest and lowest
districts. Here the plan deviation is 20.6%
Maps to Review
Draft Map A was created based on
minimal changes from the current
lines:
• Changed to decrease total deviation
Draft Map A2 ensures the
boundary between 7 and 5 follows
the current lines and uses a main
road as the divider.
Total Deviation of 7.2%
What’s Next
The City Council can make
one of two choices:
• Suggest possible changes –
adjustments can be made, but this will
require additional meetings to meet
Fair Maps Act posting requirements.
• Make a motion to adopt A2
