Elm Avenue Storm Drain Outfall Surge Control

I designed a control structure just past the storm drain outfall at the end of Elm Avenue near Swarthmore College’s North entrance. This structure will allow the large, fast-moving flow from the outfall to be discharged in a more controlled manner after rain events, preventing erosion and damage to the Crum Woods downstream of the outfall. To create my design, I consulted with experienced professionals and created a model of the contributing drainage area to determine the site needs and characteristics to decide an appropriate design. For the design itself, I used CAD and GIS software to model the size, shape, and location of the physical structures to be designed. I will pass on the design to the College so they can decide whether they actually want it constructed, but any further steps lie outside the scope of this project.
