Cross-sections of a storm detention vault feature a four-foot-thick concrete mat foundation per structural plans. The internal configuration includes a sump with an elevation of 28.00 feet, live storage capacity with a bottom elevation of 32.22 feet, and a maximum water surface elevation of 38.83 feet. Twenty-four-inch access manholes and ladders are detailed at the top slab, with flow control structures integrated within the vault space. A ten-inch outlet pipe routes to the sump pump at invert elevation 32.22, coordinating with plumbing plans for continuation.
