COUNCIL ACTION FORM
BACKGROUND:
Recently, staff was made aware of a process related to changes in the distribution of Road
Use Tax when annexing new territory to a city. Iowa Code Section §312.3(4) requires a city to
certify to the State Treasurer the increased population of the city based upon the Census
Block population from the most recent Census. The County Auditor recently contacted the City
of Ames for this information to respond to the new redistricting requirements for Story County
Board of Supervisor elections. As a result, staff is presenting this to City Council for approval.
Since 2021, the City has complet ed eight annexations. Most of these annexations do not
include a substantial number of people based upon the 2020 Census Block information. The
table below indicates the annexation, related census blocks, and estimated population. For
annexations that do not include a whole census block, staff has apportioned out the population
based upon the number of households in the block and the number of households annexed by
the City.
For the 2021 through 2024 annexations staff estimates 18 people were added to the City. The
attached map identifies the location of the annexations and the Census blocks.
2021-2024

ALTERNATIVES:
1. Approve the estimated population for the approved annexations and direct staff to
provide the population estimates to the State Treasurer per Iowa Code 312.3.
2. Modify the estimated populations and approve the estimated populations for the
transmittal to the State Treasurer.
3. Direct staff to provide more information.
CITY MANAGER'S RECOMMENDED ACTION:
There is little guidance regarding how to evaluate the populations estimates as directed by the
State law. Staff proposes to proportionally divide the census populations based upon the
number of households annexed within a block. There is only one annexation between 2021
and 2024 where this was an issue, the Hyde/Hunziker Annexation where one home was
annexed within the block.
Staff will immediately provide the required population estimates to the State Treasurer
for all the completed annexations. Therefore, it is the recommendation of the City Manager
that the City Council approve Alternative #1, as described above.
