As the worst drought since the 1950s continues to take its toll in California, innovative solutions to alleviate the state’s water woes were recently chosen as winners of Archinect’s Dry Futures competition, which sought “imaginative, pragmatic, idealist, and perhaps dystopic” proposals. The jury chose three winners for each of the two categories: speculative projects that involve “future realities and technologies not yet imagined,” and pragmatic projects that can actually be implemented in the near term.

Speculative Winners

The first place winner of the speculative category was Grassroots Cactivism, which combines a cacti farm and wastewater treatment plant, by Ali Chen, a design assistant at Bjarke Ingels Group (BIG). Chen’s winning proposal would feature nopale cactus, “a drought tolerant plant that’s fit for both human and animal consumption, and remarkably, is able to effectively clean polluted water,” according to DesignBoom. The cacti would not only require far less water to grow than California’s almond and orchard farms, but the cactus’ inter pulp could be adapted as a low-tech solution for recycling waste water.

According to the project description, the farm also aims to promote the use of nopale cacti as food and a sustainable lifestyle choice “by hosting an eco-resort marketed towards the health-conscious modern traveler, with cooking workshops, highly-rated fine dining, a water museum, and various resort amenities. The goal is to market the use of cacti in contemporary cuisine, grow awareness, provide funding for research, and slowly increase demand for a crop that can eventually replace other water-intensive forms of vegetable and fodder.”

The second and third place winners were Urban Swales: Subterranean Reservoir Network for Los Angeles by the Geofutures team at Rensselaer School of Architecture and Analogue Sustainability: The Climate Refugees of San Francisco by architect Rosa Prichard, respectively. Urban Swales imagines a series of excavations throughout Los Angeles that would collect stormwater run-off in micro-reservoirs that could then be stored and re-distributed to local communities, while also creating “urban caverns” for human and animal occupation. Analogue Sustainability would be an inhabited flood defense on Treasure Island in San Francisco Bay that wraps around the island, housing those who have been displaced by flooding and sea level rise in the Bay.

Pragmatic Winners

The first place winner of the pragmatic category is Liquifying Aquifers, a project by San Francisco-based designer Lujac Desautel. The project envisions multiple drains placed throughout the San Fernando Valley that drain back to the San Fernando Groundwater Basin, which are continually being over withdrawn “without any large-scale plan to replenish” it.

Currently 165 gallons of water per second flow straight into the Pacific Ocean from the San Fernando Valley, rather than replenishing the aquifer sitting 40 feet below the surface. “Like a giant bathtub with a conglomerate of drains,” Liquifying Aquifers is a system of basins that could take root in urban areas, like easements and parking lots, providing community spaces that will also drain water back into the aquifer.

The second place winner in the pragmatic category is Liquid Bank, by architect Juan Saez. Liquid Bank is a website and app that would offer users rewards and incentives that encourage them to use water responsibly. In exchange for developing water-saving habits, users would earn “aquos” that support water-related infrastructure projects in developing countries.

The award for third place in the pragmatic category went to Recharge City, a project by Barry Lehrman, an assistant professor at California State Polytechnic University, Pomona. The project seeks to recycle the 502 million gallons of water that is dumped into the Pacific Ocean by Hyperion treatment plant and the Joint Water Pollution control plant in Los Angeles every day by identifying recharge sites throughout the city.

The GrowOnUs floating island prototype floating in the Gowanus Canal / Balmori Associates

The Gowanus Canal in Brooklyn, New York, is one of the most heavily polluted waterways in the United States. The 1.8 mile long, 100-foot wide canal, which is a SuperFund site, has historically been home to many industries that contaminated it with heavy metals, pesticides, and sewage from combined sewer overflows. While efforts are underway to clean up the industrial sites surrounding the canal, a new experimental project, GrowOnUs, by the New York-based landscape and urban design firm, Balmori Associates, uses a floating landscape to decontaminate the canal’s water. It was launched last week behind the Gowanus Whole Foods, adjacent to the Third Street Bridge, and will eventually move to a final location near the 7th Street Basin.

GrowOnUs transforms metal culvert pipes, once used to bring polluted runoff and sewage waste to the canal, into 54 floating “test tube” planters that will clean the water through phytoremediation, a process that features cleansing plants; desalination; and rainwater collection. Each of the planters will be irrigated from one of three different types of water, according to Jessica Roberts, a designer at Balmori Associates. “Some of the planters collect rainwater in reservoirs made from recycled plastic bottles, some use canal water distilled from solar stills that allow condensation to collect,” she said. Buoyant construction material, such as bamboo, coconut fiber, and recycled plastic, allows the planters to float.

Designed by the firm’s experimental branch, BAL/LAB, the prototype draws on a year of experimentation with different plants and water types that not only have the potential to decontaminate the water in the canal, but can also adapt to rising sea levels and storm surge events.

The team will continue to monitor the prototype over the next few years through frequent site visits, according to Noemie LaFaurie-Debany, leader of the Floating Landscape BAL/LAB, and explore its full potential as a productive landscape. “We want to find out if these plants can also be productive as wildlife habitat.”

Lafaurie-Debany has many hopes for future floating landscapes. “Floating landscapes can do lots of things: They can protect the canal edge against erosion of surge, produce food and be productive, and absorb energy from the wave or the current. What interests us the most — what we really want to be able to do – is create an island that will have public space where people can go to play, to read a book or to use just like a regular green space, but in the canal.”

While the current prototype does not include public space, Roberts noted that people have been able to interact with the floating landscape. At the launch event, “fifth grade students from the Brooklyn New School participated in a series of demonstrations explaining how the island functions. It has also been fun for us to see a few people canoeing and kayaking by it. It could become such an active place,” she said.

This is not Balmori Associates’ first experiment with floating landscapes. In 2005, the firm collaborated with the Whitney Museum and the Smithson Estate to build a floating island on a 30 by 90-foot barge that was towed by a tugboat around the island of Manhattan. According to the firm’s website, “the barge was visible to millions of residents, commuters, and visitors along the Hudson and East Rivers.”

The firm has also been working on a project in Memphis that consists of a series of landscape islands on the Mississippi River. Each of the islands will provide different public attractions, including a “river overlook, a children’s play area, a performance space and wetland gardens.”

After monitoring the success of the current island on the Gowanus Canal, Lafaurie-Debany said the team is interested in finding other locations for creating new floating islands on a larger scale. “An island in the Hudson River could be more productive than one in the Gowanus. We will have to see.”

Charlotte, North Carolina street trees / Kenny Craft on Pinterest

The science is increasingly clear: trees are central to healthy, livable cities. New studies are only adding to this understanding. For example, recent research published in the prestigious journal Nature found that having 10 more trees on your block, on average, improves the perception of your own health in ways comparable to an increase in annual income of $10,000 or being 7 years younger. However, according to Cene Ketcham, a graduate student in urban forestry at Virginia Tech, the benefits of urban trees are rarely experienced equally across a city.

“We know trees have a lot of benefits. And if we know that having trees in our cities is important for our health, the converse must also be true — a lack of trees hurts your health,” Ketcham said at a conference organized by Casey Trees in Washington, D.C.

Ketcham noted that a lower tree canopy is often correlated with lower-income neighborhoods and communities of color – “areas that have historically been disproportionately impacted.” While non-profit and city-led tree planting programs are poised to bridge this gap, most are not designed with environmental justice goals in mind. The groups leading these urban tree-planting programs are increasingly aware of this problem, but what specific strategies are most effective for getting urban trees into the areas that need them the most?

Ketcham studied 11 different programs in six cities: Austin, Texas; Charlotte, North Carolina; Denver, Colorado; Minneapolis, Minnesota; Portland, Oregon; and Sacramento, California. Each of these programs have a different planting plan that accounts for inequalities. In Charlotte, for example, race and income are tightly tied together, so improving tree cover in underserved neighborhoods did not require a city-wide effort to make an impact in these communities. “But, of course, the closer you get to planting trees all over an entire city, the better off you’ll be,” Ketcham added.

The programs Ketcham identified as the most successful at getting trees into underserved neighborhoods are NeighborWoods in Charlotte, Friends of Trees in Portland, and CityShade in Austin. Based on the success of these programs, Ketcham identified four strategies city government and non-profit tree planting organizations can implement to make sure trees are planted where they are most needed:

Target Planting Areas

Successful tree planting programs use outreach efforts and highly targeted planting. “Portland canvassers go door to door in low-income neighborhoods advertising the benefits of trees. A lot of effort goes toward getting trees in where people want them,” Ketcham said. Of course, city-wide tree cover is the goal, but in larger cities where trees are disproportionately benefiting some neighborhoods, targeted tree-planting efforts can go a long way.

Build Strong Municipal and Non-Profit Partnerships

“It’s not just somebody some throwing labor in, it’s a tightly integrated collaboration,” Ketcham said. Programs that have been successful bring together public and private organizations. “Maybe the city buys the trees, while the non-profit runs the program.” In any case, it’s important that both groups take ownership of the tree-planting program.

For example, Treefolk’s CityShade program in Austin works very closely with Austin’s urban forestry department. From October 2014 through March 2015, the program worked with the city to plant 350 large-container trees and mulch existing trees in seven parks and greenbelts in Austin. According to CityShade, the organization also planted native trees to beautify, and provide shade and wildlife habitat in some of Austin’s lowest-income neighborhoods.

Reduce Property Owner Responsibility

Particularly in low-income neighborhoods, it’s important to reduce the pressure on individual property owners to plant trees. Not only are people in these areas struggling to overcome challenges bigger than increasing the tree canopy, but residents in these areas are more likely to be renters. “If you’re in an area with a lot of renters you’re not going to want to work on improving your landlord’s property. And the landlord might not even want the trees if it will change the property value,” Ketcham said. Instead, successful programs rely on volunteers and contractors to plant the trees, rather than giving trees to neighborhood residents.

However, some successful programs do provide help and guidance to residents who want trees on their own properties. Friends of Trees in Portland makes it easy for someone to plant a tree at their home with this step-by-step video.

Priotize Public Spaces

While most programs focus on getting trees onto residential properties, successful programs work on “improving tree cover, not just in residential areas but also in public spaces.” Planting trees in public spaces can provide neighborhood-wide health and environmental benefits.

For example, CityShade in Austin partnered with Austin’s watershed protection division and urban forestry department to plant thousands of small, native, tree seedlings in public areas in order to conserve water and improve water quality in Austin’s waterways. Though mainly focused on residential plantings, Charlotte’s NeighborWoods program will also help provide trees for homeowner association’s common areas when appropriate, so that everyone in the neighborhood can benefit from increased access to nature.

Conservation for Cities: How to Plan & Build Natural Infrastructure by Robert McDonald / Island Press

Conservation for Cities: How to Plan & Build Natural Infrastructure by Robert McDonald / Island Press

In my first year studying for a landscape architecture degree, our textbook for a course on environmental resources was thick, heavy, and weighed down in page upon page of extraneous jargon that obscured the portions that were legitimately interesting and useful. It’s too bad Conservation for Cities: How to Plan & Build Natural Infrastructure, by Robert McDonald, wasn’t around. Even at a quarter the length, it provides exponentially more value – not only for professionals and students in landscape architecture, engineering, planning, and the like, but also city officials, community leaders, and anyone interested in the benefits of integrating natural infrastructure into our cities.

“The twenty-first century will be the fastest period of urban growth in human history,” says McDonald, who is also senior scientist for sustainable land use at the Nature Conservancy. Will this lead to a dystopian end of nature, as predicted by some conservationists? Or will we build cities that exist in co-harmony with nature? “If the city’s plans [to integrate natural infrastructure] are conducted, what is the cumulative effect? What will the city look like? What will it feel like to live in this greener, more resilient city?”

While these are some questions we can only fully answer in the future, McDonald gives us a practical manual for getting there. McDonald’s approach – using conservation for cities – is the product of a framework rooted in the concept of ecosystem services, the many benefits nature can provide us. This is in contrast to conservation in cities, which refers to protecting biodiversity in areas or urban growth; and conservation by cities, the act of making cities more efficient in resource-use and expenditure. Conservation for cities “aims to figure out how to use nature to make the lives of those in cities better. Rather than focusing on how to protect nature from cities, this book is about how to protect nature for cities.”

Approaches to conservation – in, by, and for cities / Island Press

City leaders make decisions based on qualitative and quantitative assessments and then implement strategies, which then must be tracked for success or failure. McDonald spends the core of the book going over mapping, valuation, assessment, implementation, and monitoring methods for ten key areas of ecosystem benefits, each with its own chapter: drinking water protection; stormwater; floodwater; coastal protection; shade; air purification; aesthetic value; recreation value and physical health; parks and mental health; and the value of biodiversity in cities.

When possible, McDonald refers to specific formulas, models, software, and other tools that have proven the most successful. For the more casual reader, these technical details are easy to skim. For the professional looking for practical approaches, these details will likely be useful. It’s also worth noting here that the graphics in this pre-publication proof are somewhat sparse, and tend towards the schematic. Additional footnotes, photographs, and illustrations may be included in the finished book.

Despite the proficient use of market valuation processes, economic indicators, and the like for assessing ecosystem services, McDonald also understands that the value of nature is simply beyond human measures. While professionals and advocates for natural infrastructure are also likely to appreciate the inherent value of nature, that value is difficult to use as an argument against grey infrastructure approaches. Value is calculated in fairly strict black and white economic terms these days.

McDonald uses the “dry and academic” term ecosystem services “because it is standard in the field now, and it makes clear the economic value of nature’s benefits. But [he hopes that] the reader haven’t lost sight of the fact that always behind ecosystem services are people’s lives.”

It’s McDonald’s hope that “rather than completely bending nature to our will, we could bend our will to match nature’s pathways, at least a little bit. The science of ecosystem services gives us some of the crucial tools to follow these other pathways, if we have the love to follow them.”

For those who feel the love, Conservation for Cities offers a compelling trail head to these pathways of the future. I kept thinking I might use that old environmental resources textbook as a resource one day. This year, I finally donated it to make room on the shelf for other books. Conservation for Cities, however, is likely to stay there for quite some time.

Plan rendering of the core area of the new Alexandria Waterfront Plan / OLIN

A new master plan for Old Town, the historic center of Alexandria, Virginia, just a few miles from Washington, D.C. which has been in the works for more than five years, is now well underway, as the city opens bidding on the plan’s flood mitigation improvements. The plan will transform one of the last “undeveloped” major urban waterfronts in the D.C. area. The $120 million project, designed by landscape architecture firm OLIN, will add 5.5 acres of public open space; develop a new signature plaza at the foot of King Street, the main thoroughfare through Old town; expand the marina; create walkable connections for the length of the waterfront; and incorporate flood mitigation measures. Three new mixed-use developments have also been proposed along the waterfront, including a plan to transform Robinson Terminal North. These plans come for approval by the local planning commission and city council in September.

Phase one of the project, which will not be completed until at least 2026, will focus on core utility, roadway, and other infrastructure construction required to support the subsequent street-level improvements, followed by attention to the flood mitigation elements, one of the more controversial elements of the project, according to The Alexandria Times. At a recent talk at the National Building Museum, “Alexandria’s New Front Door: Implementing the Waterfront Plan,” it became clear that the discussion on flood mitigation illuminates the key challenge in re-envisioning Alexandria’s waterfront: how to maintain the character of one of the U.S.’s most historic cities while protecting this architectural treasure-chest from the threat of increased flooding.

Old Town Alexandria was hit hard during Hurricane Isabel in 2003. According to The Washington Post, flooding from the Potomac River swamped the historic Torpedo Factory and many areas around King Street. Along Alexandria’s waterfront, streets were navigated by canoe and kayak, as water levels reached nearly 9 feet above sea level. More recent storms, such as Hurricane Irene in 2011, were also devastating. Long-term, Alexandria’s Potomac waterfront will experience sea level rises of more than 2.3 to 5.2 feet by 2100 — according to the Waterfront Small Area Plan — and certain areas of the city now flood at least once a month, so OLIN made flood mitigation a high priority in the master plan.

Based on a 2010 flood mitigation study commissioned by the Alexandria city government, OLIN proposed a comprehensive plan that balances mitigation, cost, and maintaining views. The waterfront plan will protect against nuisance flooding at 6 feet higher than sea level through drainage improvements, a combined sea wall and pedestrian walkway, and the use of green infrastructure techniques such as swales and rain gardens. Not only will this protect Old Town against the majority of flooding, this level of protection was found to be the most cost-effective and least visually intrusive for the majority of flooding events, according to a 107-slide presentation by OLIN.

However, the historic character of the city may still be at risk during major storms. “The level was set at 6 feet so it would not destroy the character of the viewshed or the city’s historic character, but this flood mitigation will be overtopped eventually,” said Tony Gammon, acting deputy director of the department of project implementation for Alexandria, at the National Building Museum. “It won’t be a surprise to us.”

Other elements of the waterfront project, which were decided based on extensive community input, strike a balance between preserving character and improving function quite well. According to the small area plan, “throughout the planning process, Alexandrians asked for more ‘things to do’ on the waterfront.” Once a working waterfront bustling with commercial activity, Old Town’s current attractions are now primarily located in-land. The new plan aims to bring a high level of activity back to the waterfront in a new form. A public boardwalk along the water’s edge will improve access to the river, while new public spaces, including a large public park called Fitzgerald Square, will bring people to parts of Old Town that were formerly industry-dominated. Old buildings will be memorialized, views to the river from King Street will be opened up, and three derelict sites will get new mixed-use development.

According to Robert M. Kerns, development division chief for Alexandria, who spoke on the National Building Museum panel, the crowning achievement of the project has been its ability “to balance new development with the city’s historic patterns.” Preserving historic character was not only a consideration for the flood mitigation strategies, but also for the city’s new promenades and public spaces. For example, the proposed Prince Street promenade, which will end at riverfront, will have a series of formal gardens that complement the scale of the surrounding structures. “Ensuring an historic scale was important to city identity, as was following the pattern of existing buildings,” Kerns said about the proposed promenade.

But do the character-conscious flood mitigation strategies go far enough to protect Old Town from the next super storm? While Alexandria is unique due to historic character, the careful approach to flood mitigation provides a contrast to cities like New York City and Boston, which have recently held design competitions that have yielded ambitious waterfront resiliency plans in the wake of Hurricane Sandy. The projects that have come out of Living with Water in Boston and Rebuild by Design in NYC will be designed to withstand catastrophic storm events, far more than a 6 foot nuisance flood. While New York and Boston are bigger cities, and arguably at greater risk from sea level rise than Old Town, the effort in Old Town raises questions about the depth of resilience being planned and designed.

After years of debate over the Old Town waterfront, there is now some consensus on how to upgrade this historic place with new parks, better access to the waterfront, and improved flood mitigation. However, the project, which will be in the works for the next decade, ultimately proves just how much “new” residents of one of the country’s oldest cities are willing to accept. Continued flooding may be the price.

Combined sewer overflow point, Anacostia, D.C. / Chesapeake Bay.net

While the Potomac and the Anacostia Rivers gave birth to the District of Columbia, they have suffered years of contamination from raw sewage, which spill into the rivers when the aging combined sewer and stormwater infrastructure overflows. To address this issue, in 2010 the District initiated the DC Clean Rivers Project (DCCR) and began constructing massive underground tunnels that will convey contaminated runoff into the Blue Plains wastewater treatment facility. While a deep-bore tunneling machine affectionately named Lady Bird digs its way 100 feet each day at great expense, D.C. is now finally able to move forward with a more cost-effective green infrastructure plan, like New York City and Philadelphia. A new agreement with the Environment Protection Agency (EPA) and Department of Justice (DOJ) finalized in May allows DC Water, the city’s water utility, to remove one of the proposed tunnels and instead invest in turning hundreds of acres of impervious surfaces into green, absorbent ones. However, it appears not everyone will benefit equally from the new green infrastructure plan.

Under the new consent decree with the EPA and DOJ, DC Water eliminated the previously-planned underground tunnel for Rock Creek and will instead build green infrastructure that covers 365 acres. Phases of this work will start soon and the whole plan will be complete by 2030.

The neighborhoods of Columbia Heights, Takoma, Petworth, and others surrounding the Rock Creek watershed will get rain gardens, bioswales, porous pavement, and green roofs designed to capture and clean runoff, replacing the originally-planned tunnel. Near Georgetown, there will still be a tunnel but gravity, rather than an energy-intensive pumping station, will passively transfer water to the wastewater treatment plant, explains CityLab. That stretch will also get some new green infrastructure.

However, as some local activists who attended a recent briefing at the National Building Museum made clear, there are deep concerns about whether the new green infrastructure approach will benefit the Anacostia River communities any time soon. Over the years, the Anacostia, which is considered one of the most polluted waterways in the nation, has borne the bulk of environmental abuse. This is why DC Water made creating a new tunnel to address the Anaocostia River’s problems the highest priority. However, the community won’t see the benefits until at least 2022 when the new tunnel finally opens. Then, it’s expected to remove about 98 percent of the river’s pollution, making it potentially clean enough to swim in.

Meanwhile, along the Anacostia’s 8 miles, combined sewer overflows continue to occur in 17 different places, reports CityLab. So, according to these activists, the new plan has raised some environmental justice issues: it’s about who reaps the many benefits of green infrastructure first, and who gains the most long-term.

This desire for green infrastructure isn’t simply about cleaner rivers. Green infrastructure creates additional green space for the neighborhoods, reduces the heat-island effect, and improves air quality while creating jobs and increasing property values. The discrepancy in property values and income levels between the neighborhoods that will receive these benefits sooner and those that will receive a mostly-grey infrastructure fix is clear.

Despite the fears that green infrastructure can lead to gentrification, many argue that access to green infrastructure empowers communities and further marginalizes those without it. Even with the slow progress of the Anacostia tunnel, green infrastructure projects should be started sooner along the Anacostia. There are so many opportunities.

For example, along Buzzard’s Point in Southwest D.C., there are opportunities to create a new waterfront promenade that can also capture runoff with natural systems. Vacant houses in the area could also be turned into stormwater cisterns or redeveloped as parks. But, as of now, the only real plans are to create a new D.C. United soccer stadium there, which will only increase impervious surfaces, unless green infrastructure is better integrated into the design. With new incentives, green streets and roofs could spread throughout these neighborhoods, too.

The new 11th Street Bridge Park will help restore the Anacostia River ecosystems, but this project is still many years away. The new South Capitol street corridor project will bring some green infrastructure to the Anacostia area as well, but perhaps not enough. DC Water, which has been pushing for its new green infrastructure approach for years, has limited resources to fulfill its mission, and the tunnel and green infrastructure plan are great expenses. It certainly wants to bring more green infrastructure to the District, but, hopefully, these green infrastructure opportunities can be widespread so everyone benefits equally.

The Tree Church by

The Tree Church designed by Barry Cox / Barry Cox

While some aspire for grand pools or tranquil gardens in their backyards, New Zealand resident, Barry Cox, had other ideas for a 3-acre space in his own yard. Yearning for an old stone church like those he had admired on his travels through Europe, Cox united his passions for religion and tree relocation to create a 100-seat chapel at his Ohaupo, New Zealand home made almost entirely from mature trees. According to the New Zealand Gardener, as a child, Cox wanted to be the Pope, but instead, settled for the position of head altar boy in his hometown church. His interest in Christianity, coupled with his encyclopedic knowledge of trees, came full circle in the creation of Tree Church.

Cox, who owns the mature tree rescue and relocation business, Treelocations, spent only four years “growing” the church. By re-homing semi-mature trees, he accelerated the maturity of the structure, giving it the appearance of a project 20 years in the making.

Cox carefully selected from a wide variety of trees for the chapel. He writes on his website that he used live cut-leaf alder trees for the roof canopy and copper sheen for the walls, as well as camellia black tie, Norway maple, and pyramidal white cedar. These species were specifically chosen for their flexibility and their ability to be trained around the iron frame of the chapel. Some of these trees have stone-colored trunks, while others have sparse foliage, ensuring that the church can always be illuminated by sunlight.

Inside the church, rows of wooden benches form a pathway to an altar that holds special significance for Cox. The altar come from his family’s church in Shannon, New Zealand and is made of marble from Lake Como, Italy, where his ancestors are from. The copper-sheen walls of the church’s interior have thick, stone-colored foliage that must be trimmed every six weeks to maintain their lush quality.

Across from the church, Cox designed a labyrinth walk based on the walls of the ancient city of Jericho, created in 460 BC. He also constructed a large canopy from military cargo parachute to be used for after-event gatherings. Preparing for these events at the church is demanding for Cox, who told New Zealand Gardener it generally takes “five hours to mow the lawns and at least three hours of final primping to get the gardens and Tree Church to the standard to be happy for an event.”

While Tree Church was originally “designed to show how an instant garden can be created” using a tree spade, since its opening to the public in January 2015, the church is now not only “a welcomed retreat from society” for Cox, but for others as well. After urging from his friends and relatives, he decided to open the church to the public twice a week and it’s now a popular spot for photo shoots, events, and, of course, weddings. While it’s currently closed for the winter, it will open again October 2015.

Before the industrial boom that transformed waterfront cities into dirty manufacturing hubs in the 19th and 20th centuries, urbanites would take a dip in the rivers, harbors, lakes, and oceans that are a part of many cities to cool off in hotter months, enjoying a break from the steamy weather. But as these water bodies that served as conduits for cities became increasingly polluted, only the bravest or perhaps poorest swimmers would dare go in. Today, as smart cities reclaim their riverfronts as places for recreation and invest heavily in improving water quality, they are getting closer to turning their aquatic resources back into the natural swimming pools they once were.

Some cities still aren’t there with water quality, so they use floating pools in barges, which keep the river and pool water separate. In South Bronx, New York City, Baretto Point Park, which was transformed from a toxic brownfield into a park, became home to the Floating Pool Lady, a floating barge-pool in the East River, in 2008.

And in Berlin, a wooden footbridge filled with hammocks leads swimmers out to the 30-meter-long barge-pool Arena Badeschiff. There is a small cafe and bar where Berliners can hang out after playing volleyball.

A more ambitious new wave of offshore pools aims to use river water for these offshore pools, but filtering out pollutants first. In NYC, + Pool seeks to create a 200-feet wide by 200-feet long pool in a plus-sign shape; its walls will filter out pollutants using a system of membranes set right into the East River. The plus-sign shape will enable greater flexibility: the pool can be separated into four different segments for separate audiences, combined into an Olympic-length swimming pool, or opened up into a big free-for-all space. Earlier last year, they began testing a pilot membrane in the river to evaluate its performance against different conditions over 6 months.

And Studio Octopi proposes the same thing in the Thames River in London, with their Thames Baths, which will also form a swimming pool out of river water, filtering pollutants with a bio membrane. But they imagine a more natural setting than + Pool. “Imagine swimming in the river, surrounded by reeds that frame tantalizing views of the city around you. The Baths are not just for swimmers, but provide refuge and habitat for fish, birds, and a wide range of flora.”

Both + Pool and Studio Octopi are relying on grants and kickstarter campaigns to make their filtration-enabled pools, which will be managed by non-profit organizations, possible. + Pool has raised more than $250,000 but needs about $15 million.

While these floating pools are certainly great amenities, the most sustainable long-term solution will be to simply clean up these polluted bodies of water so urbanites can safely swim in them once again. This is what Copenhagen achieved in 2008. The city then took advantage of its newly-cleaned-up harbor with Harbor Baths, a set of designed pools that make their waterfront even more accessible. Locals get to it via pedestrian and bicycle paths that wind along the waterfront. And there’s even a heated bath in the complex for winter bathing.

A floating wooden deck created by Danish architecture firm BIG and JDS features a fantastic diving board, so locals can jump right into the safe harbor sea water.

The pool is also free of charge to all Copenhageners. Now, this is the idea.
