This year's Master of Professional Studies in Landscape Architecture project starts with floodplain plant communities in Binghamton. Binghamton is in the New York State at Broome County which nears the border of Pennsylvania. It surrounds with many rolling hills in the valley with the Susque- hanna and Chenango rivers. Binghamton has a population of 47,969, and its main economy is from the industries of shoes, cigars, and computer; it is also well known as six antique carousels in the world. There were three major floods happened in Binghamton in 2005, 2006, and 2011. It has caused more than $1 billion of damage, and flood was happened on the convex and confluence between the Chenango and Susquehanna River, and yet most the neighborhood was destroyed by the flood. However, flood also is an essential part of the nature and bring nutrients to the soil and keep balance the diversity in a floodplain. My focused area on this research with the questions that are: How to increase the value of plants along the river? How the floodplain plants community help Binghamton's climate change? What a buyout land (vacant land) can be used in the floodplain? According to the questions above, I have studied the plants and soil to base on the site visiting, lab tests and the design ideas with scientific research to improve the sites' condition when flooding happened. This project is funded by Assistant Professor Jamie Vanucchi in the College of Agriculture and Life Science in Landscape Architecture Department. This research not only includes the design ideas to make Binghamton a more livable city, but also with the scientific research to study the sites in a holistic view. With ample site visiting and interviews of Binghamton residents, and Broome County Planning Department, it indicates some difficult experience for the locals and other relevant depart- ments in Binghamton such as how they dealt with flooding issues.
