On October 26, 2023, Mayor Quinton Lucas of Kansas City addressed a significant concern in a letter directed to the Presiding Commissioner of Cass County, Missouri, Mr. Bob Huston. The letter outlined the apprehensions of the Kansas City government regarding the proposed construction of a landfill in South Kansas City. In an effort to prevent the landfill's development, Mayor Lucas proposed a solution: the secession of lands in South Kansas City to Cass County in exchange for the Village of Loch Lloyd. This would benefit both parties in that it could prevent the construction of the landfill.

The proposal elicited mixed reactions. Commissioner Huston expressed concern, stating that this proposition seemed to pit the residents of Cass County against each other. Mayor Lucas emphasized the City's keen interest in the Loch Lloyd area, referring to it as a significant investment opportunity.

One of the pivotal stakeholders, the Village of Loch Lloyd, responded independently to this proposition. The board of trustees of Loch Lloyd underscored the village's longstanding independence since its incorporation in 2003. In a letter disseminated to residents, the trustees affirmed that Loch Lloyd had no intention to align with Kansas City and highlighted that any annexation would necessitate their explicit consent.
