    Mobility Oriented Design: The Case for Miami’s Metrorail
    (Harvard University Graduate School of Design, 2018) Mostafavi, Mohsen; Waldheim, Charles; Keenan, Jesse
    Mobility Oriented Design (MOD): The Case of Miami Metrorail investigates the multiple facets of public transit in Miami-Dade County and its effects on the urban fabric. Broadly, this design research project seeks to understand how public transit operates within the county and why it has historically underperformed. MOD focuses on Miami Metrorail as a case study and identifies and analyzes the specific parameters that have guided transportation and development within the city’s emergent transit corridor along U.S. Highway 1. Through collaboration with a team of subject matter experts, including 2 × 4, Stamen, and CityFi, this research project synthesizes multiple perspectivesand analytical frameworks to present the historical and contemporary factors that contribute to Miami Metrorail’s low ridership and poor accessibility. It pays particular attention to the influence of public opinion, the day-to-day experienceof riders, and the relationship between the transit system and its surroundingurban context. A close analysis of these factors and an investigation of correlated prospects and issue areas informs several design scenarios that are intended to visualize and project future options and investment alternatives. Ultimately, this project proposes a menu of recommendations at a variety of scales that are meant to inform decision-making around reinvigorating Metrorail’s existing infrastructure, facilitating ridership, promoting higher-density living, and improving the rail’s integration into the urban fabric.

    Climate Gentrification: From Theory to Empiricism in Miami-Dade County, Florida
    (Institute of Physics, 2018-04-23) Keenan, Jesse; Hill, Tommy; Gumber, Anurag
    This article provides a conceptual model for the pathways by which climate change could operate to impact geographies and property markets whose inferior or superior qualities for supporting the built environment are subject to a descriptive theory known as ‘Climate Gentrification.’ The article utilizes Miami-Dade County, Florida (MDC) as a case study to explore the market mechanisms that speak to the operations and processes inherent in the theory. This article tests the hypothesis that the rate of price appreciation of single-family properties in MDC is positively related to and correlated with incremental measures of higher elevation (the ‘Elevation Hypothesis’). As a reflection of an increase in observed nuisance flooding and relative SLR, the second hypothesis is that the rates of price appreciation in lowest the elevation cohorts have not kept up with the rates of appreciation of higher elevation cohorts since approximately 2000 (the ‘Nuisance Hypothesis’). The findings support a validation of both hypotheses and suggest the potential existence of consumer preferences that are based, in part, on perceptions of flood risk and/or observations of flooding. These preferences and perceptions are anticipated to be amplified by climate change in a manner that reinforces the proposition that climate change impacts will affect the marketability and valuation of property with varying degrees of environmental exposure and resilience functionality. Uncovering these empirical relationships is a critical first step for understanding the occurrence and parameters of Climate Gentrification.
