Axios Des Moines: Alleman will drop a 6-acre parcel from its annexation proposal to resolve concerns Polk County supervisors raised last week, Mayor Bob Kramme said. Supervisors said they would reconsider the small city’s plans to expand its territory after rejecting a request to support the proposal last week if the proposal is modified. If supervisors back the plan, it could strengthen Alleman’s case before Iowa’s City Development Board. Kramme said annexing nearly 1,970 acres of unincorporated land would protect the town of about 450 people from Ankeny’s rapid expansion.
