CE 364 Water Resources Engineering Storm Sewer Project - Spring 2000 Dr. Shu-Guang Li You have been hired by a developer to help with the design of a major 'diversified living' development complex. The complex will consist of wooded areas, parks, shopping areas, multiunit housing, and larger single family estates. The proposed development site, which totals 73.40 acres, sits just outside the flood plain of a water quality limited stream, next to a large natural wetlands area (Figure 1). Because of the water quality limited designation of the stream, the developer wants to design a storm water system that will minimize the impact on the stream. One approach is to use the natural wetlands adjacent to the development site as a discharge area for the collected storm water from the development. Another idea is to design a holding pond to attenuate the flow into the stream and allow for settling of large particulates. The developer would like to use the wetlands approach since it is low in initial cost and long-term maintenance. However, a citizens committee from a nearby existing development is trying to block discharging to the wetlands since they believe the additional discharge to the wetlands will cause the water table to rise, causing basement flooding in their neighborhood. The developer has asked for a preliminary design on the holding pond to help him determine approximate costs. The holding pond must be designed such that post-development peak runoff to the river is no greater than pre-development peak runoff. Thus, your job is to design the storm sewer system for the subdivisions. You are to route the runoff through a holding pond, and design the pond to keep post-development peak flows in check. Specifically you will need to: 1. Size each pipe for its peak flow using the Rational Method . Use the 20-yr-frequency return for this analysis. Time to inlet can be calculated using the
