Page 31 1 mitigate the effects of the higher runoff rates from 2 the proposed development. 3 The bioretention basin systems are located 4 as I had previously shown. Each of these will 5 contain underdrains within the bioretention system. 6 Those will be routed to a pipe network that will 7 then be routed to the south and then to the west and 8 tie in to two different locations along Mount 9 Pleasant Avenue. 10 The bioretentions were designed so that 11 the post-construction peak runoff rates for the 12 current and future 2-, 10-, and 100-year-storm 13 events are less than 50 percent, 75 percent, and 80 14 percent, respectively, of the preconstruction peak 15 runoff. 16 During storm events, the bioretentions 17 will capture stormwater runoff which will filter 18 through the basin's media layers and drain out 19 through the network and tie into the existing 20 Township's stormwater system in Mount Pleasant 21 Avenue. 22 On the north side, where there is no 23 bioretention, you can see that the site generally 24 slopes from Mount Pleasant down towards the pad and 25 across the pad.
