SHIMP Lic. o. 5183 G ��`�SlONAL ��� STORM WATER NARRATIVE 11510 The bioretention facility is designed to be off-line, with a vault limiting the stormwater routed into the system during large storm events. Stormwater that enters inlets 4 and 5A flows through the 505 1 -yr orifice to the bioretention until the water depth in the vault reaches 1.0', then it flows through storm pipe 3-4 towards the front of the site. 500 The 10 -year water surface elevation of the bioretention facility is 0.04' over the emergency spillway, providing sheet flow. 495 Between storm inlets 2 and 3 are three 48" pipes that function as stormwater detention. They connect to the inlets via 15" pipe. Stormwater enters this detention structure from inlet 2, as 490 shown in 5/C10, and flows out through manhole 1, as shown in 2/C10. During larger storm events, stormwater passes through the overflow pipes in inlet 2 and manhole 1, as shown in 2/C10 and 5/C10. 485 4" P.Y.C.
