Urban Forest Case Studies: Challenges, Potential and Success in a Dozen Cities

Philadelphia featured in the USDA’s publication, Urban Forest Case Studies: Challenges, Potential and Success in a Dozen Cities

This publication represents extensive research, interviews and examinations into 12 cities that have begun — or are continuing — to make an investment in their urban forests in order to reap future gains.

The Eye of Sauron? Réservoir Manicouagan

I spy a circular-looking water body that looks almost like a ring, or maybe a flaming eyeball (maybe the Eye of Sauron?!) or perhaps an extremely large moat around the grandest of castles. Could it be a river or a lake? Is it Earthly? What is this un-natural looking ring of water?

While virtually roaming the New York North Country and Quebec via Google Maps; I spotted a peculiar, circular waterbody with a land mass in the middle...or was it spotting me? This "eye of Quebec" is called  Lac Manicouagan, which surrounds a body of land known as René-Levassuer Island. The island is home to 2 reserves-- Réserve de biodiversité de la Météorite and Réserve écologique Louis-Babel. Before the area was dammed in the 1960's, the water body was actually 2 water bodies-- Lac Mouchalagane to the west and Lac Manicouagan to the east.

So, what formed the two odd lakes side by side? As one of the "Seven Wonders of Canada," this now one waterbody is known as an annular lake or moat 1, which is a lake formed from a meteor impact and also called an astrobleme. When meteors have such a dramatic impact, they form complex craters with multiple rings, where the middle of the impact uplifts and creates a land mass similar to Manicouagan's. The 60-mile wide impact was so intense, the molten rock took thousands of years to cool (between 1,500 - 5,000 years) 3. The crater is thought to be 213-215 million years old and may have been a part of a multiple impact event, as it forms a theoretical line on the late Triassic continents of North America and Eurasia with other craters, such as Red Wing Crater in North Dakota and Rochechouart Crater in France 4. Interestingly, because of its unique geology, it is considered as a useful analog of other impact structures on other planets, such as Noachian Mars, for space exploration and study 8.

The uplifted region-- Mount Babel and its island, Rene-Levasseur Island-- is not only geologically interesting and the second largest lake island in the world, it has a wealth of biodiversity due to its quick transition from the boreal forest to tundra. The reservoir and island are located in the Boreal Shield ecozone and the Central Laurentians ecoregion 9. The rugged terrain hosts species from the boreal ecosystems, which are dominated by black spruce, fir, alder, jack pine, sphagnum and architectural sightings of krummholz; and tundra communities dominated by lichens and blueberries. 91% of the forest stands on the island are older than 100 years and the island houses almost 1,651 hectares of peatland 4,5. Protected peatlands are scarce, as only 3.5% of Quebec's peatlands are protected 5. Moose and caribou are common on the island.  Atlantic salmon, lake trout and northern pike can be found in the reservoir 1.

In the 1960's the lake was dammed for hydroelectric power and now supplies power all the way down to New England. The height of the dam is 214 m and some research suggests that the magnitude of the dams in this region have induced seismic activity 10. The lake gets the lowest during the heat of the summer, when New Englanders turn on thier AC's. Wikipedia reports that the chief engineer for the dam, Rene Levasseur, and Dan Johnson, the Premier responsible for the project, both died young from heart problems. Apparently, the native Innu believe that just as the men clogged the rivers, the Earth's veins and arteries, the creator responded by clogging theirs, a belief which could reflect the cultural conflicts of the region. However, this may simply be a rumor, since Wikipedia has no source for this statement. However, there are reports of several conflicts between the native communities and the energy companies. Nonetheless, it fits well into the story of Tolkien's evil eye, the Eye of Sauron....my precious!

A non-profit group, SOS Levasseur acts to protect the unique ecological and cultural resources of the island from destructive activities such as logging and mining, and performs research on the island. Another organization which encompasses all the reserves in the area is called Réserve de la biosphère Manicouagan-Uapishka, designated by UNESCO in 2007. We can't help but wonder what this place would be like if the dam were never built or the logging never occurred. Réservoir Manicouagan looks like a fascinating place to visit and we just might have to add it to the bucket list!

Humans Are Not The First Link (In the Food Chain)

Lisa Brown for NPR

In a recent NPR article Between Pigs and And Anchovies, Where Humans Rank on the Food Chain , Michaeleen Doucleff reports on how, the first time, ecologists have calculated exactly where humans rank on the food chain and how it's been changing over the past 50 years. Spoiler alert: it ain't us.

With a rise in wealth of developing nations, as a planetary-wide species, humankinds' meat to plant ratio is increasing. This increase, however, will not save us from hungry bears whose meat to plant ratio dwarfs ours...but with far less global degradation.

EcoTracks

Check out this information from Andy Giegerich, the Sustainable Business Oregon editor on Portland's new EcoTracks.  Pretty slick!

"As completion of the Portland-Milwaukie Light Rail line hits the 70 percent mark, TriMet officials want future riders to take note of what they’re calling an “eco-track” at one of the project’s new stations.

The vegetated trackway, which aims to reduce stormwater runoff, is among the first such efforts in the U.S. It will adorn a station at Southwest Lincoln Street and Third Avenue near the Portland State University campus.

The installation “will provide a colorful carpet of low-growing plants along 200 feet of light rail line,” according to the transit agency. The technique is common in Europe and consists of one-inch thick mats that contain various species of sedum, which are a hardy low-maintenance vegetation.
Stacy and Witbeck Inc. installed the track last month.

The 7.3-mile project is set to open Sept. 12, 2015. It will essentially link downtown Portland with North Clackamas County via light rail."1

Tracy Baskerville, a spokeswoman for BOP, made it clear that safety concerns have been addressed:

"We did work with a review panel including a representative from the Department of Transportation to approve the designs for the Crosswalk Project. We think it is always nice for residents to engage public art; however all pedestrians need to be mindful of the traffic, crosswalk signals and traffic lights."1

Check out these other cool crosswalks!

Reference Guide for Structural Soil

Photo courtesy of:  bdglandscape.wordpress.com

Structural soil, on a technical level, is confusing. On the other hand, it is easy to make, and compared to other complicated construction practices, it is easy to install. So what, exactly, is it? 

There has been a perceived need to create growing room for trees in our urban environment along streets and in parking lots. The soil under sidewalks, adjacent to sidewalks, and in sidewalk cutouts is usually compacted to prevent the walk from settling. This prevents many tree roots from growing in soil under the walk. Growth can be severely restricted, creating unhealthy trees, especially in sidewalk cutouts, but if soil is not compacted, the walk will settle.2

A solution that creates root space without compromising soil strength for sidewalk support is "structural soil" or an "engineered soil" mix beneath the sidewalk as shown below (See: structural soil detail). This strategy appears to be especially beneficial for clayey and loamy soil where compaction beneath walks can become quite severe. One disadvantage of the engineered soil shown below is that settlement could be beyond acceptable standards in the U.S.2

The need for this soil has been assisted by federal and local stormwater regulations requiring reductions and sometimes elimination of run-off from spreading pollutants, destroying streams, and in our older cities, overburdening sewer systems.

There are options out there when shopping for your structural soil and now that an overabundance of muncipality urban design guidelines are requiring its use, the inventors of each are all vying for your support. We break each down below and hopefully help steer you in one direction or the other, depending on your project needs.

SilvaCell

• DESCRIPTION: Simply put, they are milkcrate-esque plastic boxes that are buried underground and filled with dirt.1 They were developed by a well spoken, well read, and very convincing landscape architect, Jim Urban.  We believe that he believes what he says, and so do a lot of other folks.  This passion, and the fact that these things just look like they make sense, accounts for their success.  Click here to buy some.

• PROS:  Like we said, these things seem to work, at least that what Jim Urban tells us.

• CONS:  Money.  They are expensive and quite honestly are the first thing to get the axe when we start the value engineering process.  Please, we are not whining about value engineering, just build it into your design on the front end like everyone else and roll with it from there.

• WHERE IT HAS BEEN USED: Lincoln Center, New York City; the Olympic Village in Vancouver; Martin Luther King, Jr. National Memorial, Washington, D.C.

CU-Structural Soil

• DESCRIPTION: CU-Structural Soil is a mix of dirt and rocks designed to bear the load of pavement and whatever rolls across it, while leaving enough open space underground for tree roots, air and water. It’s since been licensed and sold to builders and landscapers across the U.S. and Canada. A mixture of 20-percent soil and 80-percent rocks (by weight) gets packed around a layer of soil surrounding the tree’s roots. The stones are all the same size and the ratio ensures that each stone touches another. When concrete or other loads press down on the soil, the stones create a rigid skeleton that bears the load while the soil itself stays loose.1 It was invented by Cornell University professor Nina Bassuk, and now holds the license for the product.1 You can find producers here.

• PROS: Its cheap, and chances are any engineering or landscape architecture firm already has a passable specification laying around. Our advice: read your spec. If you haven't had a qualified soil scientist/structural engineer write you a fresh one in a while, it may be time. 

• CONS: It can be tough to compact if it isn't dry. We ran into this problem on a big project and it was a struggle. In this instance, our spec was tight, but any time problems pop up during construction, it almost doesn't matter whose fault it is, it can hurt the client. Make sure you remind and double-remind the contractor that this is a tricky part of this soil and they need to pay attention.

• WHERE IT HAS BEEN USED: Johns Hopkins Hospital, Sheikh Zayed Cardiovascular and Critical Care Tower and The Charlotte R. Bloomberg Children's Center, World Trade Center, New York City; San Francisco Zoo Hippo Exhibit, San Francisco, CA; Ritz Carlton, Washington, D.C.1

Sand-Based Structural Soil

• DESCRIPTION: The name is pretty much self explanatory. Instead of mixed-in aggregate, this is a sand based solution. A top layer of crushed rock allows air, water and minerals to get through to surface roots. The rest is filled in with sand that presses together under pressure, but leaves microspaces and remains loose enough for roots, water and air to move through. Compost gets mixed in to help hold on to water and nutrients. Landscape architect Robert Pine helped develop it, but it remains an open-source strategy and is not for sale as a product.1

• PROS: It is most likely better for trees because it doesn't compact as well. Having said that, we don't know for sure that is true. The folks who will want to sell you the two products above will tell you that it won't compact. We currently have a big project under construction that is using one of these sand-based structural soils, we will keep you posted on what we find. 

• CONS: You never know what you are going to get. Again, this is not a product, it is as open-sourced as you get, and there is not one specification that is going to guide you

• WHERE IT HAS BEEN USED: Alcohol, Tobacco and Firearms Building, Washington, D.C.; Federal Reserve Bank, Boston, Mass.; coming soon to the Brooklyn Bridge and Brooklyn Botanical Garden, New York City.1

Radical Cartography

Photo courtesy of architizer.com/blog/radical-cartography

With Design with Nature, Ian McHarg pioneered the concept of ecological planning. Mcharg did not invent cartography, a practice that can be traced back to the ancient Greeks (what can't?), nor did he necessarily invent applied cartography: that is often attributed to fellow Scotsman, Patrick Geddes. In 1915, his suggestion that plans be made for Place, Work, Folk spawned the method of planning-by-layers (Meller 1990, 46). 1

Suitability Analysis from Design With Nature

McHarg was successful in clearly documenting and describing the layered analysis process, and  has been considered one of the premiere minds in landscape ecology, planning, and architecture. Perhaps a less well known, but no less inspiring counterpart can be found in William Bunge, Jr. who looked at and mapped cultural behavior in and around Detroit. Bunge's work was similar to that of William “Holly” White, a master urbanist, organizational analyst, journalist and people-watcher in his own right, but at the same time, much, much different.

The distinction lies in the fact Bunge’s maps are as argumentative as he is.  They demand social equality for a community that was ignored and abandoned and record it as a snapshot of truth in time. He mapped unconventional measurements:  quantities of store bought toys and rat bites, to mark the disturbing inequity he saw before his eyes. In one map, he compares the number of bars to the number of playfields in each Detroit neighborhood. Another, titled "Where Commuters Run Over Black Children," is an indictment of poverty, white flight, and President Gerald Ford himself. Below are excepts from Fitzgerald and An Atlas of Love and Hate; these maps portray Bunge's time in Detroit, and his ability (and sometimes inability) to organize the landscapes around him. 2

He shown a light on the way things were in a way that the powers that be at the time were not comfortable with. He wasn’t talking about how to better gentrify a park in NYC or how to build out the Jersey Shore. He was dangerous because he focused on the minute patterns of human movement and behavior, revealing the machinery that orchestrates our activities. His maps are based on statistics, truth, and "damn good graphic design." 2

For his efforts, again and again he lost tenure and was briefly blacklisted by the United States government as a communist sympathizer. Bunge published An Atlas of Love and Hate: Detroit Geographies in 1969, then followed it in 1971 with Fitzgerald: Geography of a Revolution (Geographies of Justice and Social Transformation). Due to his combination cartographer/community activist role, his maps are both a romantic time capsule and an invaluable source of access to a period of fundamental change in the "Great American City." Mathematically exact yet gentle, Bunge lived in the communities he mapped, and his maps remain haunting and inspirational artifacts through which we can watch the Detroit of our grandparents become the Detroit of our parents.2

Yes, Handbags, But What Else?

Photo courtesy of Tesler Mendelovitch

Recently we discovered this post on one of our favorite sites, Materia. Innovation for Design at different scales comes from inspiration at multiple scales. The handbags from Tesler Mendelovitch got the gears turning in our heads...how can this be used in architecture? in the landscape?

The principle for the Tesler Mendelvotich work is visible in a range of work based on what the designers call ‘diamond wood’ geometric surface finishing. The wood-textile fusion, similar to materials such as Foldtex, has led to plinths, pedestals and small tables. Recently, this work branched out into wearable pieces. The advantage of the wood-textile combination here is that it answers to users’ requirements. As an example, clutch purses made from the material provide the necessary resilience and hear-wearing attributes, while also being flexible and soft to the touch.1

The studio has settled on a few designs, incorporation various types of wood that suit the design type well. Although the process is not visible, the resulting forms are the result of many generations of design refinement and testing. Tesler Mendelovitch experiments with wood, cutting, folding and bending.1

With any material, but especially with wood, it takes time to understand the material. The particular lesson here is that working on the scale of the material itself – small panels of lightweight wood – allows the designer to learn from the wood.1  The applications of lessons learned from these microscale creations have yet to be discovered...maybe you can send us your ideas!
