Portions on the eastern side of the site, including the <br />proposed southern entrance, drain to a bioswale <br />running along the north edge of the property near <br />the soccer field (Photo 6). The bioswale outlets via <br />a 12 inch concrete pipe to the storm sewer system <br />for the adjacent residential subdivision to the north <br />(see Photo 7.) From this connection, the storm <br />sewer drains northeast approximately 350 feet, <br />through a series of 12 HDPE pipes, to an existing <br />detention pond (the outlet to the pond shown in <br />Photo 8, Photo 9 shows a portion of the pond.) The <br />detention pond outlet flows west to a control <br />structure near 20t' Drive SE, then back to a <br />protected outlet point east of the detention pond <br />(photo 10 and 11). At this point the drainage from <br />the pond joins the drainage path described from the <br />Northwest Discharge Point. The total distance from <br />the bioswale outlet to this point is approximately <br />450 feet. <br />Photo 8.
