This thesis, Outbreak File: Sibley County, researches and examines the ecological footprint in order to describe an efficient way to design and protect communities from the threat of a zombie apocalypse. Discovering how to reduce the size of a footprint in a community is the realistic goal to reach a high level of sustainability. Zombie-proof design is essentially a new way to enforce the ability to sustain in architectural design. Through research in this thesis, the possible outcomes of an a potential zombie apocalypse, we can take the basic requirements a community needs in order to survive the threat for several years. Located in the middle of nowehere, central Minnesota about 70 miles southwest of Minneapolis, the community shelter proposed in this thesis accomplishes the needs of a community and guarantees safety to those who hold up in the structure through the duration of the outbreak without help of any outside sources. This community shelter, approximately 300,000 square feet, can house a small community based on the population of the local region.
