Their goals included keeping populations among the seven wards as close to each other as possible, keeping the boundaries as compact as possible, and not un-seating any current member of the city council.
The seven options range from keeping the current boundaries as is, or making a variety of possible changes to reflect population changes since 2010. Staff also hoped to follow a recommendation from the Illinois Municipal League to insure population differences among the wards would be ten per cent or less.
Only one of the options satisfies all the criteria.
Starting with a population of nearly 43,000 (42,981), an ideal ward in Moline would have 6,100 (6,140) residents.
