Evan Davenport, Intern

RISD MLA I Class of 2019

RISD ASLA Student President

Evan Davenport joined SDG in summer of 2018.    After graduating from the University of New Hampshire in 2009 with a B.S. in Civil Engineering and a minor in Architectural Studies, Evan’s work focused on stormwater management and site civil design.      Eager to be more involved in the design process, he began working for an architectural firm in 2015, which ultimately led him to seek a Masters of Landscape Architecture at the Rhode Island School of Design as a means of merging the two fields.  He is now entering his thesis year of the MLA I program at RISD where he plans to continue his research into public access and availability to resources within small-scale coastal cities.
