DATE:10-28-25
DEPT:P&H
SUBJECT:CERTIFYING ANNEXATION AREA POPULATIONS TO STATE TREASURER
COUNCIL ACTION FORM
BACKGROUND:
Iowa Code Section §312.3(4) requires a city to certify to the State Treasurer the increased
population from an annexation. The requirement relates to the distribution of Road Use
Tax. The population is to be based upon the Census Block population from the most recent
Census.
Three annexations have been completed since City Council last certified annexation area
populations in July of this year. An item on the October 14, 2025, City Council agenda
assigned these areas to voting precincts.
Two areas (Borgmeyer annexation with properties along Hyde Avenue and JT Warehouse
annexation) include an addition population of 23 people based upon the 2020 Census Block
information. As the Borgmeyer annexation area is made up of portions of several census
blocks, staff has apportioned out the population based upon the number of households in the
block and the number of households annexed by the City within each particular block.
The ISU Research Park annexation did not contain any households and thus no population
was assigned.
An attached map shows the relationship between the annexation areas and Census
Blocks. Table 1 includes the populations of the three areas.

ALTERNATIVES:
1. Approve the estimated population (23) 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:
Staff proposes to proportionally divide the census populations based upon the number
of households annexed within a block. This is the method used previously to certify the
population of annexation areas. Therefore, it is the recommendation of the City Manager
that the City Council approve Alternative No. 1, as described above.
