A site plan for a proposed warehouse located near Pittsburgh, Pennsylvania (Region 1) is shown in Figure 12-24. Inlet locations and incremental drainage areas have already been determined. The on-site storm sewer system connects through an easement to the existing system in Brickel Avenue. Using a design chart like that in Table 12-4, complete the hydraulic design for this storm sewer system. Key parameters are as follows:

Design storm: 15-year

Pipe material: reinforced concrete

Manning’s n: 0.012

Minimum pipe size: 12 inches
