Additionally, the council received a midyear budget update for fiscal year 2025-26, approving adjustments including a $512,000 increase in expenditures across all funds and addressing structural deficits. The meeting also featured public comments on community amenities and safety, and discussions on traffic impacts related to the Town Center development, with expert testimony indicating minimal additional congestion due to the nature of the proposed mixed-use development.
