Furthermore, the project has been designed to meet the Rice Creek Watershed District <br />infiltration .requirements of 0.34 inches of runoff and dead storage requirements of 2.5 inches of runoff. A <br />large portion of the runoff from the site is directed to a series of infiltration basins /ponds located along the <br />southerly and easterly boundaries of the site or through underground infiltration chambers. Runoff from <br />these systems eventually outlet to a wetland (Wetland 2 on Figure 7 of the EAW) that is connected to <br />another extensive wetland complex (Wetland 1) that is located in the George Watch Lake watershed. <br />
