Pop-up events; local enhanced enforcement actions. Allows a locality by ordinance to establish pop-up event zones, as defined in the bill, for the purpose of taking enhanced enforcement actions within such zone if the pop-up event may significantly disrupt normal community operations. A local governing body's presiding officer, a locality's chief law-enforcement officer, and a locality's chief administrative officer must be in concurrence to activate such zone. The bill requires a locality to give notification of a pop-up event zone through an online webpage, providing as much advance notice as is practicable. The bill further grants the authority to take enhanced enforcement actions such as (i) declaring the pop-up event zone a gun free zone, (ii) establishing temporary speed limit reductions and enhanced traffic fines within the pop-up event zone, (iii) establishing and enforcing occupancy limits on both public and private property within the pop-up event zone, and (iv) declaring a curfew for unaccompanied minors. The bill allows a locality to recover all relevant costs and fees incurred from the designation and enforcement of the zone directly from event organizers.
