Koller Heliport

The closure is directly linked to the heliport's status as a private-use facility tied to a specific individual. Following the death of its owner and operator, Gerald Koller, there was no longer a purpose for the heliport. This is a common reason for the closure of small, private airfields, which cease operations when the owner no longer flies, sells the associated property, or passes away. It was not closed for economic, military, or accident-related reasons.

The site is a large, private residential estate. Satellite imagery of the coordinates shows the property with a large home, several outbuildings, and a pond. The physical infrastructure of the heliport is still partially visible: a circular concrete helipad is clearly identifiable on the property, located adjacent to a large outbuilding that likely served as its hangar. The former helipad appears to be used as a simple concrete slab, possibly for vehicle parking or recreation, and the property functions solely as a private residence.

Koller Heliport was a private-use (PVT) heliport. Its significance was not public or commercial, but rather tied to its owner, Gerald 'Jerry' Koller, the prominent owner of the Koller-Franchino Ford dealership in Waukesha, WI. The heliport, located at his private residence, was used for personal and business-related transportation. Operations would have consisted of a single private helicopter operating under Visual Flight Rules (VFR). The ICAO identifier, US-10961, is a location identifier assigned by the FAA to private aviation facilities that do not meet the criteria for a standard 3- or 4-letter code, which is typical for facilities of this nature.

There are no known plans or prospects for reopening Koller Heliport. As a decommissioned private facility on private residential land, its reactivation is highly improbable. A new owner would need to have a specific need for a heliport, own a helicopter, and complete the extensive FAA and local regulatory process to have it re-certified. Given that the original purpose is obsolete, the likelihood of it ever returning to aviation service is virtually zero.
