8. Defining Communities
3/10/2016
 There are many ways to define communities
 Best way to define a neighborhood remains to hear from the people
who live there
 Some examples of communities of interest could include:
 School attendance areas; housing developments; neighborhoods around parks;
horse-friendly neighborhoods
 Some communities want to be unified to maximize their voice in single
trustee area election. Others (often school attendance areas) want to be
divided so they have multiple representatives on the board.

 Comply with the Federal Voting Rights Act,
 Avoid racial gerrymandering,
 Are contiguous, and
 Follow major roads and other visible features
 The maps differ on:

 Whether Council Members are paired (and, if so, how many)
 Compactness

14. For Discussion
March 23, 2016

 These are NDC’s initial draft plans. Through discussion and
revision, we hope they will evolve into Corona’s preferred map.
 What do you like and dislike about each map?
 Are there parts of different maps that might be combined into
an alternative map?
 Are there changes to a specific map that you would like to
consider? (Remember, changes must be population balanced.)
 For further review: there are PDF maps and demographic
profiles on mapcorona.com, plus an online interactive map.
