Streets in and around Port Richmond officially prohibited to truck traffic. (Map by .chris & SEENO)

I recently gave a short presentation at a Port Richmond neighborhood group on some updates from the air quality monitoring we completed this summer. We do air monitoring in the hopes of improving air quality in the neighborhood, and as I’ve mentioned quite a bit, a lot of the air quality issues in the area we assume are related to the highway and truck traffic.

Above is a map of streets that trucks are not allowed to drive on and below is a guide for making those restrictions. Many of these restrictions are either unknown to drivers or unenforced by local authorities. Many of the routes haven’t been amended in decades and are usually scattered throughout the community, only established when residents petition to the City.

Trucks snake in and out of the neighborhood, blow past truck route signs, and clog even the large arterial streets with extreme amounts of traffic congestion. There hasn’t been much planning dedicated to addressing this issue, and we are unsure what affect the highway expansion will have on congestion.

Traffic has to move through and along the neighborhood, but Philadelphia hasn’t really thought about exactly where it should go. Truckers, too, are unsure, meandering through the neighborhood looking for the correct truck entry point, burning more fuel and releasing more particles than they need to in the process.

So, where do we want to put these trucks?





Air quality in Philly neighborhoods is mostly determined by proximity (how close are you to some of our city’s largest polluters). It is reasonable to believe that distance from where you are to the Sunoco refinery or I-95 has a significant impact on the quality of air you breathe. But, as I mentioned before, the current air quality monitoring network doesn’t give us a clear picture of this. This isn’t true for the whole of the city, as air pollution from places outside of Philadelphia can travel into the city by way of large-scale air currents. The heavy pollution from Beijing hanging in the Los Angeles basin is a good example of this type of air quality travel. At the neighborhood level, though, what you are close to means a lot for what you breathe.

Above is a land-use map of Philadelphia I made depicting the variety of different uses in the city. For those of us that spend quite a bit of time looking at maps and thinking about space in Philadelphia, it isn’t much of a surprise: a long stretch on industrial use on the western edge of the Delaware river that snakes down around the expanding southport; dense commercial and transportation use in our very own central business district, center city; a sea of yellow and orange residential and vacant land in our urban neighborhoods; and large tracts of contiguous industrial and transportation in the southwest marking the space of food terminals, the refinery, and our somewhat international airport. The pie chart of land use by square mile included here shows that just over half of land in the city is taken up by residences and transportation alone. Read More

Port Richmond is under construction. Walking through the streets in this old, working-class neighborhood in Philadelphia, it is hard to miss a ripped up sewer plates, diverted traffic, or the large plumes of dust coming off a nearby construction site. Much of Philadelphia’s infrastructure funnels through this neighborhood and, apparently, much of it needs to be replaced. Reconstruction, replacement, and decay are fantastic moments to rethink exactly what our infrastructure does to us. That is, not only what it does for us—as we commonly think about infrastructure—but what it does to us as well.

Clean Air Council (where I work) has been working with engineers, scientists, planners, and neighborhood residents in Port Richmond to collect air quality data in the area, attempting to remedy one giant urban problem: What are the air quality impacts—and, by association, health impacts—of port operations and heavy traffic along the I-95 corridor? We know from other research in other places that infrastructure affects health: ports and highways are major sources of hazardous pollutants, such as particulate matter and ozone, that pose significant health risks to those who live nearby. However, we can’t say the same thing about the actual air we actually breath in places like Port Richmond. We can look outside and speculate on what might be in the air, but if we aren’t standing directly next to one of Philadelphia’s 10 air monitoring stations, we have absolutely no idea.

The world health organization recently designated diesel exhaust as a known carcinogen, citing recent studies on the effects of high concentrations of exhaust on coal miners’ health. Diesel exhaust is one of those things in cities that produces high levels of particulate matter and NOX (a precursor to ozone). There has been some discussion over whether a study on miner’s is relevant to the topographically different cityscape (we’re not locked in a mine! We’re in a wide-open city where air can actually move!). This is a good point. We still don’t know, though, where it moves, how concentrated it actually is, and who is bearing most of the burden of diesel emissions in Philadelphia.

Back to infrastructure. This is all a result of a nearly unending list of infrastructural failures, changes, anomalies, decisions and so on: port worker housing developed in the places closest to ports; I-95 was built along the river and is still growing in this same direction; Philadelphia’s air monitoring network is not extensive enough to understand ALL air quality patterns in the area; the Panama canal is expanding, prompting an expected increase in goods to the east coast; diesel trucks in the port are old and many truck-drivers can’t afford to replace them; and, finally, our bodies are vulnerable to many of the emissions that result from these infrastructural processes (this is what infrastructure can do to us).

There is invisible dust in the air around us. It feels immaterial, fluid, and certainly difficult to see. It is often only apparent in our occasional smog clouds over the city, a plume of black smoke from a diesel truck, or a short wheeze from a young asthmatic Philadelphian.  The purpose of this blog—and the purpose of our air monitoring project in Port Richmond—is to increase our understanding of the health and air quality effects of Philadelphia’s critical infrastructures in an effort to do them in different, healthier ways. We’ll update regularly with stories, thoughts, news, histories, sounds, photos, research, and ideas about air quality, Port Richmond, health, and infrastructure.
