Overview This project explores multiple layers of meaning embedded in an industrial area enfolded by campus and residential neighborhoods in Minneapolis, MN. The legacy of industrial processes is cleaned by phytoremediation processes and represented by repurposed grain silos. Natural history is recalled by the presence of reintroduced bison. This wild island, with remnant silo sentinels, would be engineered to be self-sustaining and provokes questions about cyclical history, the fear of wildness within the city, and the growth/ land use paradigm.

CONTEXT MAP OF SOUTHEAST MINNEAPOLIS, SAINT PAUL, AND ST. ANTHONY PARK
Executive Summary The Southeast Minneapolis Industrial area (SEMI) and rail yard sits between the two Twin Cities campuses of the University of Minnesota. Many systems and intense development forces are at play here. An in-depth research and analysis process revealed that this site includes a few large landowners and many smaller parcels, a drained wetland, and a lasting legacy of pollution from previous industrial processes. How can and should this area change over the next century? Can we learn from the history of this place and create a plan to reuse, re-wild, and re-identify instead of bowing to redevelopment pressures?
about a controlled repopulation of large keystone species. Here, this theory would be tested by inserting a wild area into an urban pollution-laden environment. This posits questions about wildness and safety within a controlled “human environment,” and also questions the purpose of a park, restoration, and conservation. SEMI can be a new type of park where wild bison are allowed to roam, and where people can view them from a safe distance. In keeping the remaining grain silos on the site (to be used for remediation and viewing structures), the presence of industrial production is juxtaposed against this manufactured wildness.
This is not a typical brownfield remediation and master plan project. “Normal” remediation efforts focus on capping or mechanical remediation for human occupation, or cleaning to industrial re-use thresholds. What if we changed this expectation and instead cleansed the land gradually for ecosystem and research needs? Alternative “natural” methods can be used such as planting aspen (Populus tremuloides and deltoides or hybrid species), sunflower (Helianthus annus) and boneset (Eupatorium perfoliatum) as hyperaccumulators. The areas with heaviest pollution can be cleaned using fungal remediation (mycoremediation) by piling dirt on remnant building slab foundations and adding spores from the oyster mushroom (Pleurotus eryngii). Somewhere below all the current bustle of train cars, factories, machinery, vacant buildings and expanses of rail ties lies the course of Bridal Veil creek, a small tributary to the mighty Mississippi. Bridal Veil is one of many subverted creeks within the city of Minneapolis and any one of them could make an interesting study. The wet legacy of this watercourse (which causes problems for the warehouses and loading docks) and the context of the many projects yet to be realized within this milelong stretch provides ripe territory for research and design. This proposal seeks to re-wild the Southeast Minneapolis Industrial area by remediating the polluted areas in situ, and returning the landscape to a wet prairie where bison roam. Rewilding is a theoretical idea in ecology

Adjacent to the University of Minnesota’s Twin Cities campuses and straddling the border between Minneapolis and Saint Paul, the Southeast Minneapolis Industrial area is situated in an important location. Rail lines converge here into a switching district. Rail has been dominant here for over a century; the first rail line from Saint Paul came up along the river and through the easiest grade to downtown Minneapolis: the rail followed low-lying wetlands that formerly occupied this area. The rail was initially named the Saint Paul and Pacific Railroad, then became the Great Northern Railway, J. J. Hill’s great enterprise line that stretched from the Twin Cities and Great Lakes through to Seattle, WA and Portland, OR. This route became the northernmost trans-continental line and was completed in 1893 (see http://en.wikipedia.org/ wiki/Great_Northern_Railway_%28U.S.%29 for more information). The railroad enabled the passage of many raw goods from the plains and forests to be harvested and processed at the mills and silos here in the Twin Cities. As the historic aerials show, SEMI once included more silo and factory complexes than remain today. On this land which was once a wetland surrounded by prairie and oak savannah, the rail and silos became king. The last few decades have seen significant removal of both silos and contraction of rail lines: the land below TCF Bank Stadium was filled with railroad lines. The land at the northwest edge of the site was also formerly a small switching yard for Chicago and Northwestern Railroad (now defunct).

Many industries are and were within the boundaries of this site. Perhaps the most notable was the Valentine-Clark Corporation, a creosoting plant just northeast of the site boundary. The creosote would wash or drip off the telephone poles as they were being treated, and flow straight into the nearby ponds and Bridal Veil Creek. According to the MPCA, the remaining pollutants in the surface water, groundwater, and soil around Valentine Clark is highly toxic.
“Site Contamination: Soil, sediments and surface water in Bridal Veil Open Space have all been found to be significantly affected by a variety of chemical contaminants including: polynuclear aromatic hydrocarbons (PAHs); pentachlorophenol (PCP); several metals [including lead, copper and thallium]; and polychlorinated dibenzo-pdioxins/polychlorinated dibenzofurans (PCDD/PCDF). The Valentine Clark Superfund Site is believed to be the source of most of these contaminants. The former Elm Street Ash Dump occupied part of the site and also may have contributed to the contamination.” Minnesota Pollution Control Agency. Valentine Clark State Superfund Site – Bridal Veil Open Space Recommended Contamination Response, g-27-12a (July 2007). Accessed online: http://www.pca.state.mn.us/index.php/view-document. html?gid=3207
Various other areas as indicated on the pollution map must also be evaluated and remediated. The former Elm Street Ash Dump is mostly capped by parking lots and building slabs, but testing should be performed to detect leaching. ADM had a dump near the U of M transitway (see the 2001 SEMI/Bridal Veil Falls AUAR and Master Plan, page 50, http://www.minneapolismn.gov/www/groups/public/@cped/documents/webcontent/convert_282754.pdf for more details), and though the area is capped, there was an epoxides spill here many years ago. Where Bolander/SKB Environmental is located now, the county had a recycling facility and there are rumors of contamination. Legally and morally, we tend to re-use polluted land so that the bad areas get worse and the clean areas stay clean. In practice this makes sense, but in the long run it would be much better if we stopped these discharges and accidents from ever occurring. City planners and zoning codes group these polluting industries into conglomerated areas, which arguably keeps residential areas safe from the pollution but having so many polluters together also makes the remediation process more complex. As we move into the next century, technology will undoubtedly improve and hopefully our planning, production, and pollution containment and reuse processes will as well.
For measured pollutant concentrations, see the Valentine-Clark Final Minnesota Decision Document g-27-12b, (October 12, 2007). Accessed online: http://www. pca.state.mn.us/index.php/view-document.html?gid=3208
Railroads are also heavy polluters, from the creosote in railroad ties leaching into the surrounding soil, to iron deposits ground from the wheels and rails, to the weed-killing sprays used to keep the right-of-way clear. All areas that are or were railroad-owned need to be evaluated and treated accordingly.

Bison and the Railroad When Landscape Architects talk about ecological restoration, they often look to pre-settlement vegetation or other indicators of predevelopment conditions. As students, we are taught to question the preconceived notions of what restoration means, how disturbance regimes and succession occur, and what time period is significant. In light of this, can a project that seeks to re-insert bison and engineer a prairie on former industrial and rail yard land be called a restoration? Bison are the historic keystone species of the plains, and they form part of the identity of the Midwest as an ecological region. A map earlier in this document showed the historic range of bison through North America. Although bison were exterminated from Minnesota around 1870 as the prairie was being plowed up to make way for cities and farms, they still hold a place in our collective memory. As the railroad was extended, it allowed more people to live on the “frontier” and provided more access to bison hunters. Ostensibly the railroad was built for tourism and industry, but the timing of massive bison killings in the 1880s coincides with the rise of railroads and manifest destiny. An 1889 survey by William F Hornaday found only 1091 bison remaining (see http://www.americanbisonsocietyonline.org/AboutUs/Timeline. aspx).
“The long term (beyond 20 years) may hold redevelopment potential for areas of the current BNSF Railyard. Fully utilized at present, BNSF suggests that future consolidation of their railyard facilities in the metropolitan area could make property available for redevelopment in an area called the Central Redevelopment Area in this report.” Alternative Urban Areawide Review (AUAR) for SEMI/Bridal Veil Area, Volume 1 Executive Summary (May 2001), page 10, accessed online: http://www.minneapolismn.gov/www/groups/public/@cped/documents/webcontent/convert_282754.pdf
With an adjacent large yard in Saint Paul and a much larger switching area in both Northeast Minneapolis (Columbia Park) and Columbia Heights, SEMI’s rails could be phased out and repurposed.
Where bison have become a symbol of our nation’s lost nature, the railroad has always been a symbol of human ingenuity and industry. Bridges and tunnels are hailed as massive engineering feats, and large switching yards are impressive reminders of the complex network and logistics that keep our economy running. These switching yards leave marks on the urban fabric of cities; the northern half of Minneapolis has many superblocks comprised of neat rows and curving lines of tracks. In a city grid with many nodes, it should be feasible to consolidate and increase efficiency. While railroad companies are notoriously protective of their property, the next 50 to 100 years will surely bring changes to the industry. Even over the last 20-50 years, SEMI has seen track consolidation (see 1991 and 2010 aerial images earlier in this report). In addition, the 2001 SEMI/Bridal Veil AUAR stated that BNSF does (perhaps) intend to phase out more of their tracks.

Releasing the Bison at Belwin Conservancy, Washington County, MN
From Belwin’s Website: One of the motivations behind bringing bison to the Belwin Conservancy is education. Although they have largely disappeared from this area, bison were once an integral part of this landscape. As might be expected, bison are extremely well-suited to this environment and with very little assistance, they thrive given only native prairie. http://www.belwin.org/bison/

No; they may go their way to their manifest destiny, which I trust is not mine.... I would rather be a captive knight, and let them all pass by, than be free only to go whither they are bound. ...

What could SEMI become? Instead of an expanse of railroad tracks, SEMI could become something different, something new, exciting, and experimental. Re-wilding projects have been consciously undertaken in large, rural land areas around the world. These include places like the Oostvaardersplassen in the Netherlands and Rainham Wildspace on the eastern edge of London, UK. The former Rocky Mountain Arsenal near Denver, CO, was accidentally rewilded by many kinds of animals as that huge tract of land sat unused for decades, before being cleaned by the US Government and Shell Oil and later was officially recognized as a wildlife preserve. These examples of re-wilding, whether intentional or unintended, show that this process can work. This project seeks to extend the idea of re-wilding and hybridize it with remediation and land reuse, to create an iconic reminder of our historic landscape in the Twin Cities.
27
28
Remediation Cleansing the pollution can be accomplished through various techniques, four of which are appropriate for this site. Perhaps more techniques will be developed in the near future. Processes particularly suited to removing the pollutants at SEMI include phytoremediation using Aspen (Populus tremuloides and/or deltoides), perennial crops (specifically sunflower Helianthus annus, and boneset Eupatorium perfoliatum), mycoremediation (fungi applied to soil), and water filtration. Remediation is a scientific process, but results are not predictable so a regular testing cycle should be developed. Researchers and the Minnesota Pollution Control Agency (MPCA) should evaluate and make a determination when the soil is clean enough. Larger areas needing low-intensity remediation can be planted with perennial crops or Aspen trees, while the areas with heaviest pollution can be diluted by mixing compost with the soil and/or piling the soil and adding mushroom spores through a process called mycoremediation. Groundwater pollution would also be addressed by Aspen plantings, but additional cleaning may be needed via pumping water through treatment ponds. Most remediation projects focus on bringing pollution levels to either human occupation or industrial use standards set by either the EPA or state pollution control agencies. This project, by the act of planning for bison, questions the typical drivers for remediation.
29
PERENNIAL PHYTOREMEDIATION
Boneset and sunflower are planted first because they are hyperaccumulators. Researchers will monitor growth and accumulation of pollutants. Plants will be removed in a regular cycle. After significant remediation has occurred, a mixed wet prairie can be seeded.

EXISTING CONDITIONS PLAN
Phasing Over the course of 75 years, this area can be re-claimed and rewilded into a 350 acre bison preserve. Because the American Bison (Bison bison) like to wallow and dig into shallow soil, the top layers of the entire area must be cleaned enough to keep the bison healthy. While we do not know the exact extent of pollution, this project assumes that a majority of the area will need treatment or modification. Remediation on this scale cannot occur overnight, nor should it be achieved by importing soil from elsewhere and capping the underlying problem. Therefore, the phasing plan consciously does not introduce bison until approximately 30 years in the future, but these first bison are introduced in a more highly visible area. If remediation targets are achieved earlier, the bison can be introduced sooner.

MASTER PLAN
Design With fences composed of re-used site material and a landform berm, the boundaries of SEMI will not feel like typical livestock enclosures. To protect both the bison and people, the fence enclosing the bison area must be at least 6 feet tall around the entire perimeter. This can be accomplished by a combination of stacked, free-standing gabion baskets, and gabions incorporated into landform edges. New research facilities and greenhouses will be gradually added along the seams of the bison enclosure to enable observation and augment the prairie plant stock or food source for the bison. The silos will be re-used as a visitor’s center (Peavey), a viewing tower and bison shelter (Kurth) and a rockclimbing wall (Calumet).

Two public areas are included on the plan. One is developed early in the phasing process, allowing representative experiences of the remediation process and giving visitors a view to the bison (plan at left). A new bike path is built along a berm on the back edge of this first area. The berm acts as a wall for the bison on the interior side, and as a raised viewing area for the public. Trees planted in tight grids allow people to experience the feeling of a remediation grove. Small mounds mimic the mycoremediation dirt piles. And as time progresses, a visitor center with research functions can be created within the former Peavey Electric Elevator building. The second public area is possible at a later phase, more likely 30 to 45 years after this plan begins. Here toward the center of the bison enclosure, a fenced-in 7.5 acre area surrounding the Calumet grain elevator. The silos can be used as part of the wall separating people from the surrounding bison; in this area, the relationship of humans to bison is inverted since the area is surrounded on three sides by fences, providing a unique experience. A focal point of this area is the existing pond and rock climbing on the Calumet complex. In addition, the park is attached to a potential rails-to trails connection that continues up the former railroad tracks toward Van Cleve Park and I-35W.

Conclusion Although many plans have been proposed for this area, none look very far into the future. After comparing the proposed Biomedical Discovery District, private development plans, transit-oriented development spurred on by the Central Corridor Light Rail Transit, the Grand Rounds Missing Link, and the twelve-year old SEMI/Bridal Veil master plan, it is clear that none of these proposals are perfectly aligned with one another. This project allows for many of the same activities to occur but in new ways. Existing research can be transformed into hybrid work studying bison, prairie, and remediation. New facilities can be built while preserving or augmenting the remaining silos. Larger public open space can be created as a seam and transition between new development and the future bison enclosure. Furthermore, in a larger sense, this project questions traditional land planning and development assumptions, our society’s willful acceptance of pollution and mechanized remediation processes, and the loss of identity through ignorance of our natural and industrial past. SEMI would not be the same place if all of the silos are torn down. Similarly, this region lacks the presence of bison, our former keystone species and an icon of the frontier. Juxtaposing the two within SEMI re-inserts and re-values these two important aspects and re-interprets an identity for the Twin Cities.

Do not prune terminal leaders or branch tips. Prune co-dominant leaders.
Prune broken branches, rubbing or crossing branches, water spouts, and narrow crotch angles. Remove tags and labels.
Do not wrap trunk or stake tree unless specified by Arborist or Landscape Architect.
Cut away all bailing ropes, and remove top of wire basket. Check for suckers, or girdling roots (if container grown) and trim them. 3 to 4 inch muddle ring. Mulch 2 to 4 inches deep, kept 1 foot from root flare as shown. Hole must be 2 or 3x diameter of root ball, and of sufficient depth to cover root ball. Area around rootball is deeper so that the tree sits on a soil pedestal as shown. Widen and score hole wall prior to planting. Set tree with root flare exposed. After setting tree, partially backfill hole with amended soil, per specifications. Water tree to settle soil, then complete backfill.
