This document analyzes runoff at the entrance to an apartment complex called The Ridge. It calculates the current runoff from a 100-year storm using the SCS Curve Number method and finds 7.58 inches of runoff. To reduce pooling that occurs at the entrance, it proposes adding a bioretention cell. With the cell, runoff is calculated to decrease to 5.45 inches. The bioretention cell is deemed the best option because it significantly reduces runoff in a cost-effective and logistically feasible manner.
