City proposes deannexation of 40 acres from River Commons to Riverside District

The Idaho Falls City Council convened on July 10, 2025, to discuss several key agenda items, primarily focusing on proposed boundary changes and the development of the Riverside District. The meeting began with an overview of the geographical context of the area under consideration, located north of Sunnyside and south of Henkaria, adjacent to the Snake River.

The council reviewed the current status of the River Commons District, which is set to undergo significant changes. A proposal was introduced for the deannexation of over 40 acres, currently marked in purple on the presentation slides, to be incorporated into the new Riverside District. This move is driven by the impending closure of the River Commons District and the need for ongoing remediation efforts in the area.

A historical analysis of the site revealed that it has transitioned from agricultural use to gravel extraction, which has contributed to the current conditions and eligibility for redevelopment programs. The council discussed the deteriorating structures present in the area, particularly along Milligan Road, where many buildings date back to 1920 and exhibit signs of obsolescence. The condition of Milligan Road itself, along with stockpiles of debris from past gravel extraction activities, further complicates development efforts.

The council identified several criteria that support the need for redevelopment in the area. These include the presence of deteriorating structures, inadequate street patterns, and a lack of connectivity to major arterial roads. Milligan Road, described as a dead-end street, poses significant challenges for access and development, with proposed future connections hindered by existing debris and contamination.

Additionally, the council noted issues related to faulty lot layouts and diversity of ownership, which complicate the development process. Many lots along Milligan Road are too small for effective development and lack proper street access. The concentration of ownership in certain areas, while not extensive, disrupts the continuity necessary for cohesive development.

In conclusion, the meeting highlighted the urgent need for boundary adjustments and redevelopment strategies in the Riverside District to address the area's deteriorating conditions and facilitate future growth. The council plans to continue discussions on these proposals in upcoming meetings, emphasizing the importance of strategic planning for the region's development.
