Enforceable Infill & Capital Commitments
Mandatory Dedicated Turn Lanes: Commercial infill projects must construct dedicated north/south right-turn deceleration bays prior to final occupancy issuance.
Dublin Joint Signal Coordination: Hilliard and Dublin intergovernmental agreement requiring automated signal timing synchronization across the Hayden Run corridor.
School Zone Access Management: Curb cuts prohibited within 450 feet of school entrance drives during peak drop-off/pick-up hours without explicit police and staff waiver.
Multi-Use Trail Extension: Mandatory 10-foot asphalt path dedication along the eastern frontage linking into the Heritage Rail-Trail spur network.
Critical Infrastructure & Campus Choke Points
Davidson High School AM Stacking: Parent drop-off and bus queues regularly back up onto Avery Road through-travel lanes between 7:15 and 7:55 AM.
Hayden Run Roundabout Spillback: Heavy southbound Dublin commuter traffic fills the roundabout circulatory roadway, blocking westbound entering traffic from Hayden Run.
Pedestrian Safety Near Campus: Student foot traffic crossing Avery between school sports facilities and residential subdivisions faces high-speed vehicle friction.
Narrow Pavement North of Rings: Transition segments nearing the northern city limit narrow abruptly, reducing clear shoulder recovery space for bicyclists and buses.
