I'm interested in better understanding the ongoing geological processes that shape St. Louis and the Mississippi Valley region. So far, I've been looking into the history of seismicity in the region, focusing on the fascinating but little known history of the New Madrid earthquakes of 1811 and 1812 -- the most devastating earthquakes to have hit the US east of the Rockies. I've also been exploring how St. Louis and surrounding areas are dealing with the possibility of another earthquake occurring in the future. According to one article I read, one of the biggest uncertainties is what would happen to the heavily engineered Mississippi River in the case of another major tremblor. The shaking could break the levees, flooding wide areas along the river and creating cascading effects. The flow of the river might also reverse completely, as occurred during the New Madrid earthquakes.
On these possibilities and the lack of scientific consensus surrounding intraplate seismicity in this zone, see this article in The Atlantic.
On current efforts to create earthquake hazard maps in St. Louis, see this overview on the US Geological Survey site.
For a deeper dive into the history of the New Madrid earthquakes, see this book by historian of science Conevery Bolton Valencius.
A brief essay about St. Louis' notorious eminent domain history--
--along with 2 recent St. Louis Post-Dispatch articles about "urban renewal" projects that are scheduled to reoccupy the Mill Flats area, which hosted the most notorious episode of displacement of African-American communities: the Chouteau Greenway project (will it serve or displace low-income St. Louisans?); and SLU's Mill Creek Flats high-rise project, which certainly will, and whose name seems to me an especially tone-deaf if gutsy move...

Prior to the 1970's, many US cities managed stormwater through piped conveyance systems. Flooding was once considered the most significant risk associated with rainfall. System builders built water infrastructure to accommodate volume. Most cities in the US have what is called a combined sewer system (CSS). This system pipes stormwater and municipal wastewater together. The water is then treated and then released into receiving bodies. St. Louis is one of the rare cities (Baltimore, where my research is based is another) that has a municipal separated stormwater system (MS4). In a separated system, a system of pipes keeps stormwater separate from other wastewaters.
In the 1970's ecological research, some of which came from the EPA's National Urban Research Program, began to demonstrate that nutrients in runoff were responsible for environmental pollution. In turn, municipal engineers transitioned to thinking about tools and techniques for decreasing this nutrient load. In St. Louis, the separated system operates under a federal consent decree with the EPA where the city must reduce the overall percentage of nutrients (nitrogen and phosphorus) carried through runoff. The most recent strategy for managing this problem is Green Stormwater Infrastructure (GSI). Although the problems associated with GSI are of local relevance, they are managed through state and federal governance strategies.
While GSI is difficult to define, many times installations feature landscaped elements that aim to mimic the pre-development hydrological processes of a given site. In urban areas, these projects often utilize vacant lands or reduce existing impervious surface cover. Many planners and community groups also suggest that GSI provides additional social benefits through an increase in community green space, reduction in urban heat island, and improved property values.
This image from Missouri Coalition for the environment brings together the many suggested benefits of implementing these technologies. The diagram also provokes some questions that may interest us in our project; Does GSI represent a paradigmatic shift in techniques of stormwater management? Does natural or environmental mimicry in engineering projects act as a corrective to the anthropocene, or are these technologies merely a response? How are the social, economic, and technical benefits of GSI calculated and have attendent burdens been considered as well?
