Now, final confirmation won’t come until on Oct. 10 meeting.
The council approved map 1C this week, with an amendment to move Stone View Drive and the southeast intersection of Vista Heights Drive and Los Altos Parkway to Ward 4, represented by Councilman Mike Carrigan, from Ward 3, represented by Councilman Ron Smith, in order to retain Vistas homeowners association members within a single voting bloc.
That change has disrupted a target population threshold for all wards and prompted city planners to develop new redistricting proposals for consideration.
Redistricting the city’s voting wards comes on the heels of 2010 U.S. census data showing the population in Sparks grew to 91,057 from about 77,000 over the last decade.
Municipal code requires that no single ward have a population that exceeds any other by more than 5 percent.
But the census reports that population growth since 2003 — the last time the voting wards were redrawn — has upended this balance and triggered the necessary adjustments.
According to staff reports, when the total population is divided evenly among the five wards, Ward 1 is under-populated by about 10 percent; Ward 2 is under-populated by 3 percent; Ward 3 is under-populated by 16 percent; and Ward 4 and Ward 5 are overpopulated by 26 percent and 3 percent, respectively.
Adding the Vista Heights area has increased the population of Ward 4 by about 230, according to city planner Jim Rundle. This adjustment means that Ward 3 is now 6 percent smaller than Ward 4, thereby unseating the target population balance.
To fix this, a new map has been drawn to include the Ward 4 change, add the southeast corner of Sparks Boulevard and Baring Boulevard to Ward 3 from Ward 5, and move the area immediately south and west of East Greenbrae Drive north of Prater Way to Ward 5 from Ward 3.
This map, known as 1F, meets the target population range for all five wards, Rundle said.
The City Council members will have to choose between this map and an un-amended map 1C at their next meeting, scheduled for 2 p.m. on Oct. 10.
