Design a storm sewer system for Whitebirch Court and Warren Place, located in northern New Jersey, which are shown in Figure 12-25. The storm sewer connects to the existing sewer in McDonald Drive at the manhole shown at the intersection. Your design should include drainage area delineation and hydraulic design using a chart like the one in Table 12-4

System layout is shown in the figure. Assume all roads are curbed and crowned. Also, assume that no runoff enters Warren Place from the road to its south. Wooded areas are delineated with a symbol for wood lines. Suggested design parameters and pipe slopes are shown below:

Design storm: 25-year

Pipe material: reinforced concrete

Manning’s n: 0.012

Minimum pipe size: 12 inches

Runoff coefficients: paved, 0.90; grass, 0.35; wooded, 0.25
