The Penn State undergraduate Matthew Moffitt won the 2013 ASLA Student Award of Excellence in General Design by showing that not all dredge is created equal. Moffitt’s project, Dredge City: Sediment Catalysis, uses dredged material from the Maumee River, a tributary of Lake Erie, to restore a brownfield site, reestablish migratory bird stopovers, and connect urban and ecological systems, all in the context of an elegantly detailed park. By processing the material dredged from a shipping channel on the Maumee, Moffitt looked at Toledo, Ohio, the most heavily dredged port in the Great Lakes, and asked how one of the lake’s greatest polluters—the Maumee dumps a considerable amount of phosphorous into Lake Erie, causing algae blooms among other problems—can become a source of lifeblood for the city. We talked with Moffitt, who now works at Michael Van Valkenburgh Associates, about how he conceived the project and how dredge is becoming a hot research topic.

How did you become interested in dredging as a source of remediation?
The project originally began as a studio project during my senior year at Penn State. The studio origins were in Toledo, Ohio, so that’s how it all began. My professor, Sean Burkholder, is very knowledgeable about dredge and is often working in the greater Ohio region. There are several postindustrial sites in Toledo along the Maumee River, and the river feeds into the Western Basin of Lake Erie. We were given one of several sites along the river, and the site I chose was Edison Park. The challenges of the site included [combined sewer] outfall, dumping postindustrial material, and adjacency to one of the newer bridges and the downtown skyline.

His studio prompt was very inspiring, and from there I started making the connections between dredged material and the sediment itself, and from there it blossomed. The general goal for the studio was to use dredge or sediment from the shipping channel for a park design. The assignment was pretty broad, so we had a lot of room to use our imaginations.

Maybe you’ve noticed things have been a bit more lively here at the  Landscape Architecture Magazine blog of late, and you’d be right. In addition to cranking up our posting to twice a week (!), we’ve been thinking a bit about what we might do to expand our audience and create more of a community of landscape-minded readers.  There are many changes afoot that will be rolled out in 2014, but we’d like your help with some low-hanging fruit, namely our blog roll.

Yes, the blog roll is a venerated tradition in the webs, but often it just becomes a mutual linkfest that highlights the same five well-known news aggregators over and over. We’d like to do something more substantial, and we’d like your help, friendly reader.

Our current blog roll (over on the right—->>) is pretty good, but some of our favorites aren’t posting so much anymore and our sense is that there are a lot more landscape-oriented blogs out there than there were a year ago when we first made the list. That’s where we’d like your help.

So tell us your favorite landscape blogs in the comments below.  We’re interested in original content, rather than aggregators, and we’re curious about anything that shapes landscape, from agriculture to climate to infrastructure to policy to design theory to design tech.  

Here are some we’ve been reading lately–

Rust Wire. Always a fave. News and urban grit from the rust belt.

BakkenBlog. North Dakota oil and gas.

Big Picture Ag. Perspectives on ag policy, food, science.

The Prairie Ecologist. Notes on prairie ecology, restoration, and management.

Small Streets Blog. Life at a plausible scale.

Gizmodo. New life under Geoff Manaugh of bldgblog, but you knew that.

Garden Rant. Various garden-related posts with a strong point of view.

99% Invisible. Blog to accompany the excellent design-oriented podcast.

What are you reading and liking? Suggest blogs in the comments or on Twitter @LandArchMag.

Five and a half years ago, I learned we might lose our home to oil drilling. Strangers could suddenly be in control of our land, scraping, drilling, fracturing bedrock, leaving the wastes—with no legal responsibility to us. What would happen to the local economy, to services everyone takes for granted, in the Wild West atmosphere of an oil or gas “play,” when boomtown populations double overnight? So began my forced education about petroleum engineering.

They make Toyotas in Guangzhou. And Hondas. And Nissans. It’s a major car manufacturing center. But it will soon be more difficult for people here to own cars themselves.

For a while, it seemed like rising oil prices and shrinking supplies might help us kick our greenhouse gas addiction. But if recent research holds true, we won’t be able to rely on the market to rein in global warming any time soon. In a paper published by Harvard’s Geopolitics of Energy Project, Leonardo Maugeri, a former oil executive and current research fellow, concludes: “Oil is not in short supply. From a purely physical point of view, there are huge volumes of conventional and unconventional oils still to be developed, with no ‘peak oil’ in sight. The real problems concerning future oil production are above the surface, not beneath it, and relate to political decisions and geopolitical instability.”

Maugeri does a comprehensive analysis of oil resources and predicts production could increase by nearly 20 percent in the coming decade and prices could collapse, thanks in part to the new opportunities for tapping tar sands and producing shale oil by hydraulic fracturing. “The Western Hemisphere could return to a pre-World War II status of theoretical oil self-sufficiency,” Maugeri writes, “and the United States could dramatically reduce its oil import needs.” (more…)

In the past day I came across two clever ways to make use of one of our most common trash items: the plastic beverage bottle. The EPA says Americans generated 31 million tons of plastic waste in 2010, only 8 percent of which was recovered for recycling (a sad statistic), so there’s no lack of fodder for inventive people who want to find ways to put plastic bottles back to work. Here you see (POP)culture, a canopy designed by students from the University of Nebraska-Lincoln College of Architecture and featured on The Blog Aquatic by David Connell. Connell lauded it as “a beautiful example of…making trash too valuable to toss.” Elsewhere, Shea Gunther on Mother Nature Network profiled five low-tech innovations that are making a difference in the lives of people in the developing world, including an incredibly simple and inventive plastic bottle light.

The luxury home builder Toll Brothers will pay a $741,000 civil penalty and make major changes to the way it manages stormwater on its construction sites, following allegations that it violated the Clean Water Act on more than 600 occasions. The settlement, announced Wednesday by federal officials, addresses 370 sites in 23 states.

Among the permit violations alleged by the U.S. Environmental Protection Agency (EPA) and the U.S. Department of Justice were the “failure to stabilize disturbed soil” and the failure to properly install and maintain “stormwater controls such as silt fences, swales, sediment basins, sediment traps, storm drain inlet protection, and construction entrances and exits.” (more…)
