End of Case Study Task Assignment
Remember our following focal question:
The Anacostia Watershed Society sued D.C. Water Sewer Authority (DCWASA) in 1999 for violation of the Clean Water Act for having combined sewage and runoff flow into the Anacostia River. In a settlement in 2004, DCWASA agreed to build three underground water storage tunnels over the next 20 years. Several approaches and mechanisms have been suggested to alleviate the problem. Which approach(es) is the best for DC?
1. Based on what you’ve learned, start to refine and improve your map. You may use individual post-it notes to help you to re-write, modify or refine the items as you go. You may want to move the post-it notes around several times to see which spatial arrangements best represent the ideas and relationships you think are important.
As before, draw lines between ideas that are related, and write a brief (2-3 words) description next to each line that defines the nature of the connection. Do not forget to identify or define what different types of lines, shapes, or colors represent in your diagram.
2. At the end of the exercise, you will turn in your own systems map with a one or two paragraph narrative with your assigned code (not your name!). The written description should explain the reasoning behind the changes you made to your system map from your original one including any additions or subtractions you made that relate to the focal question.
