A four-way fire department connection assembly features four six-inch by 2.5-inch hose connections with integral clappers and metal break-away caps facing the driveway, positioned at a minimum height of 36 inches above grade on a six-inch standpipe equipped with a check valve and two rows of highly reflective tape. An all-weather sign with contrasting text instructs that the FDC supplies onsite hydrants. A concrete curb ramps from a zero-inch flush height through a 24-inch transition to a six-inch vertical curb height with variable curb transitions determined by the plan.
