(COLORADO SPRINGS) — Olympic City citizens have one last chance to vote on Tuesday, June 17, in a special election that would decide how the city will develop in the next couple of decades.

The special election features a single ballot question regarding the Karman Line annexation, asking voters to approve or reject Ordinance 25-26. The ordinance concerns annexing the area known as “Karman Line,” which consists of 1,876.24 acres located northwest of Bradley Road and Curtis Road, west of Schriever Space Force Base.

The annexation vote has caused pushback from various community members, with a petition even being submitted for the annexation to be reconsidered after it was initially approved by the City Council in December. Individuals have previously expressed concerns about water, emergency services, and uncontrolled growth, among others.

The land is currently vacant and agricultural. If approved, developers hope to build 6,500 homes, and the project would take around 20 years to complete.

To vote, individuals need to turn in their ballot to an official drop box by 7 p.m. on Tuesday.
