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.

Restoration of Jackson Park / Project 120

On a rainy afternoon, surrounded by musicians, dancers, and dignitaries, artist Yoko Ono spoke at an “earth healing” ceremony, celebrating the dedication of the site of what will be her only permanent installation in the Americas, Sky Landing. The installation will be in Chicago’s Jackson Park, on the Wooded Island, which is currently undergoing extensive restoration work, including the reconstruction of natural areas and the creation of a new pavilion.

Sky Landing will be located on a site adjacent to the Osaka Garden in Frederick Law Olmsted’s bucolic park. The site is historically significant, as it is the location of the original Phoenix Pavilion, which was built in 1893 as a part of the World’s Fair Columbian Exposition to promote American understanding of Japanese culture and as a means to unite the East and West. The original pavilion burned to the ground in 1946.

Ono responds to this history. She explained her inspiration for the piece to Americans for the Arts’ Nora Halpern: “I want the sky to land here, to cool it, to make it well again.”

Though the actual form of Sky Landing, which is expected to open in 2016, hasn’t been revealed, the land has been formed in anticipation of the installation. Two crescent shaped mounds of earth curve into each other, creating between them a space for sky, framed by land.

The healing ceremony was organized by Robert W. Karr, Jr., president of Project 120 Chicago, which is leading the restoration effort in Jackson Park. Karr spoke of the Japanese concept of kanreki, or the idea that rebirth happens every 60 years. In 2013, exactly 120 years after the original dedication of the Phoenix Pavilion for the 1893 World’s Fair, 120 Japanese cherry trees were planted. In a continuation of this theme, Sky Landing asks that peace and understanding be reborn.

Toshiyuki Iwado, Consul General of Japan at Chicago, said the site and Ono’s new piece represent a legacy of unity between American and Japanese cultures. Here, people will be able to experience the “richness of nature and the harmony of culture and peace.”

Ono spoke of feeling Chicago’s “incredible, incredible intense opening of the heart.” She has long felt a deep connection to Chicago, saying in an interview with Halpern that “Chicago makes me nostalgic about way, way back when I was a little girl in the 1930’s. I don’t really know why.”

Derek R. B. Douglas, vice president for civic engagement, University of Chicago, spoke of the importance of parks and green space in providing community members both access to nature and opportunities for solitude. Describing Sky Landing as “one more way for local residents to connect to the park,” he reminded us of the importance of the park as a place for people to gather, engage with the natural world, and find respite.

At the ceremony, Chicago Mayor Rahm Emanuel also took the opportunity to unveil a public art initiative, Public Art Chicago: 50 for 50, which will create a public art installation in each of the city’s 50 wards, because “public art enriches the experience of public space.”

Meanwhile, no word yet from the Obamas and Chicago city government as to whether they will take a piece of Jackson Park or nearby Washington Park for the $500-million Obama presidential library. In May, word leaked from the Obama library foundation that one of these two Olmsted-designed historic parks will be the future site, to the dismay of historic preservation and park advocates.

Designed for the Future / Princeton Architectural Press

“What gives you hope that a sustainable future is possible?” In Designed for the Future: 80 Practical Ideas for a Sustainable World, Jared Green — the same Green who edits this blog, and, full disclosure, was my boss when I was a communications intern at ASLA — offers 80 thought-provoking and frequently inspiring answers to this question from landscape architects, urban planners, architects, journalists, artists, and environmental leaders in the U.S. and beyond. The book’s tone is highly conversational and reflects the voices of the book’s contributors. Each passage is the result of an interview with Green, who serves largely as curator for this reading experience.

To those in the field, the names are like a who’s who of respected leaders in these professions. But while professionals will certainly enjoy it, this book is aimed squarely at the public, as it’s as scrubbed-free of design jargon as possible and offered in bite-size pieces easy to pick up for a few minutes at a time or read entirely through on a weekend afternoon.

It’s largely successful in this aspect, capturing the essence of the ideas at the core of each real world example without losing the reader in technical terms and excess detail. However, in a few cases, the description is so sparse as to leave uncertain exactly what the project is about.

Some of the projects feature new technologies applied in innovative ways. Lighting designer Leni Schwendinger, now with Arup, is inspired by Illuminate, a three-year research program in six European countries showing the way to the future of light-emitting diode (LED) lighting in public spaces. The study examined not only at energy savings and carbon reductions, but also the quality of light in terms of brightness, color temperature, and color rendition (whether the object illuminated looks true to life). It’s the artificial nature of these latter qualities that tend to sway many designers away from LEDs, despite their energy savings, but this study shows they are being improved, and LEDs may soon be able to use “intelligent controls to create malleable lighting” in our parks, plazas, and museums.

Jonsara Ruth, a professor at The New School / Parsons, discusses Mushroom Board from the firm Ecovative, a product that uses mycelium, the “roots” of mushrooms, to literally grow an organic Styrofoam replacement. Styrofoam is an incredibly polluting material, but Mushroom Board, a cutting-edge use of bioengineered materials that can be grown to almost any shape and size, is completely biodegradable. Imagine appliances coming packed in Mushroom Board or homes insulated with mushroom in the walls instead of spray-in foam.

Many projects feature materials and infrastructures from the past that have been given new life to serve contemporary needs. Landscape architect Thomas Woltz, FASLA, Nelson Byrd Woltz, describes how Braddock, Pennsylvania, is in the process of transforming much of its abandoned and toxic industrial lands, re-envisioning them as a place for urban farming and healthy community initiatives.

And Peter Harnik, Hon. ASLA, director, Center for City Park Excellence, Trust for Public Land, describes how Midtown Greenway in Minneapolis is a railway that has been converted into one of the most successful trails for cyclists and pedestrians. Built in a trench to not interfere with auto traffic, it’s a delight for its users who can go for long stretches without having to negotiate intersections and vehicle conflicts.

One overarching theme is the need to further connect social, environmental, aesthetic, and economic benefits that have been considered for too long in isolation. For decades, we’ve known, in theory, that achieving quadruple-bottom line benefits is essential for sustainability. These existing projects show how multiple benefits can be achieved in the real world, and the positive impact they can have on communities and the environment.

Green offers a lovely quote in his introduction from science fiction writer William Gibson: “The future is already here, but it’s just not evenly distributed.” Environmental advocacy and action can so easily just focus on the negative or emphasize only the compromise and sacrifice necessary for “saving the planet.” The examples in Designed for the Future show that not only is our future not all doom and gloom, but there’s plenty to be excited about here and now. The future is here. Now let’s start spreading today’s successes around as widely as possible.

Mexican landscape architect, architect, and urban designer Mario Schjetnan, FASLA, who recently spoke at Harvard University Graduate School of Design, is recognized for his built works that are fueled by a deep concern for the cities of his native Mexico. GSD landscape architecture department chair Charles Waldheim, Affiliate ASLA, introduced Schjetnan as one of today’s foremost landscape architects, and said the new appreciation of landscape architecture in Mexico can be greatly attributed to the efforts of Schjetnan and his firm, Grupo de Diseño Urbano.

The majority of Schjetnan’s work is in Mexico and Latin America, where he has grown awareness of the field by demonstrating the many ways it serves growing urban centers, while also reaching beyond the discipline to do the work cities need. He has an unusual profile: he is Mexico’s leading landscape architect but also internationally-recognized.

Schjetnan outlined a set of principles that “establish the condition to immerse ourselves in the profession.” Along with “nature of place, collaboration, sustainability, and culture/history/precedent,” he lists “inter-disciplinarity” and the “conceptual continuum.” For an example of inter-disciplinarity, he points to innovation in the sciences, which often comes out a mix of different disciplines. “Inter-disciplinarity creates these new hybrids we are working in.” He acknowledges that no project addresses just one principle in isolation.

Schjetnan used his work at Parque Ecológico Xochimilco in Xochimilco, Mexico to talk about the nature of place. For Schjetnan, any project on a historical or natural site requires finding the “deep meaning of place,” the “starting point” from which to begin a project. “It encompasses the aesthetic, ecological, and the poetic…” This approach has particular relevance in a country with so many archeological sites. (At one point that evening Schjetnan even relates a bit of a joke: Once asked how many archeological sites Mexico had, “one of the best anthropologists” answered quite beautifully with a simple “only one; it’s called Mexico.”)

Xochimilco, one of Mexico’s historic sites, required Schjetnan to really immerse himself. It led him to discover the deep tradition of Mexico’s “chinampas,” an agricultural system based on raised plots of fertile land within the lake beds of the Valley of Mexico (see image above). Drawing on this tradition, which Schjetnan calls “the best technological invention of pre-hispanic Americas,” the new park design at Xochimilco reimagines their original use within contemporary water infrastructure, using the forms of these “marvelous islands created by man” to filter and pump water back into the lake. Schjetnan is making traditions visible and viable.

In the case of Parque Eco-Arqueológica Copalita in Huatulco, Mexico, the team, on its journey to discover the nature of place, created a new park along with an entirely new understanding of the relationship between archeology and environmental history. The archeological eco-park marries the two and no longer sees vegetation as being destructive. In practice, this new understanding has meant training the staff not to remove old growth trees from the precious pyramids.

While not removing trees may be the “right” thing to do in one scenario, in another circumstance it may be the wrong thing. Take the firm’s work in the forest of Chapultepec Park in Mexico City. Schjetnan tells a fascinating story or how thinning the forest for health — yes, that means removing trees in this case — had to be done first on a nearly invisible demonstration plot in order to gain public support. Otherwise, he might once more risk being accused of cutting down trees. Schjetnan has the wisdom to let the vegetation be the agent of design.

A more recent project is his firm’s first large-scale contaminated, post-industrial site: Jardín Natura Parque Bicentenario in Ciudad de México. With a slab foundation dominating the site, the garden’s topography is entirely shaped by the bio-regions’ soil profiles. The more soil a tree needs, the higher the ground. Schjetnan excitedly walked the auditorium through a detailed longitudinal section that cuts through each of the distinct bio-regions of the garden. His garden demonstrates not only where but also how trees grow. What a novel way to refresh the role of a botanical garden in a city where not only the buildings but also the ground are rising up to the sky.

William Wenk / Wenk Associates

William Wenk, FASLA, is the founder and president of Wenk Associates. This interview was conducted at the ASLA 2014 Annual Meeting in Denver. 

Denver has made great strides in its efforts to become one of the more sustainable cities in the US. What have been the major successes over the past 20 years? Where does the city still need to make progress?

The urban corridor, along the front range of the mountains between Colorado Springs and Fort Collins, is one of the fastest growing metropolitan corridors in the country. The most significant improvement has been the new regional light rail network that Denver Metro area voters approved approximately 10 years ago. This system has generated opportunities for transit-oriented developments (TODs), a” hub and spoke” system well on its way to being built out. It will be one of the most comprehensive in the country. The goal is to create more urban environments on sites often found in a suburban context.

In the heart of Denver, there has been tremendous interest in development at the rail stops. But increased density along the rail corridors can’t possibly handle the levels of growth and need for housing. In addition — with the exception of a few light rail stops — the expansion of transit in the heart of Denver is proving to be especially difficult. A number of established neighborhoods are being transformed by much denser infill development where there’s no transit other than our bus system, which isn’t very well-used. Increased density, especially in older central city neighborhoods, has been tremendously controversial. For example, the Cherry Creek District, which is an upscale shopping area two miles from downtown Denver, is achieving urban density, but isn’t served by transit. The same is true for the Lowry infill, New Urbanist development, where higher densities are being criticized because of increased traffic in surrounding streets. Controversy surrounding increased densities in the center of Denver will continue to be an issue for years.

To provide a better transit option the heart of the city, Denver is considering on-demand transit or circulators, which Boulder has found to be very successful. A system of circulator buses in Boulder called the Hop, Skip and Jump, has been a hit. We also have Zipcars and BCycle, our bike share system, that provide other options to owning a car, especially in areas close to the downtown. Because we’re such a car-oriented city, getting a typical family to shift from two cars to one car is a big deal, in spite of all of the innovations to date.

The state’s population is increasing at about 2 percent per year. As a result, we are once again seeing sprawl — low-density development at the urban fringes. Since 2008, sprawl had slowed down considerably, but it has been heating up again.

Among the city’s sustainability goals: by 2020, Denver seeks to increase transportation options so only 60 percent of commuting trips are made by single-occupant vehicles. How will the city achieve this? Is compact urban development the way forward here?

Colorado has 5 million people now but is projected to grow by 2 million people in the next 15 years. Accommodating that level of growth is going to be an enormous challenge. Colorado is a very popular destination to move to both for Millennials and Baby-Boomer seniors who are following their kids who now live here.

We have daunting issues related to growth along the front range, which is where most of the growth will occur. We can’t accommodate it all with denser infill development, although there are currently thousands of units of apartments under construction right now in the heart of Denver. We’ll also see more units coming in the TODs along the light rail system.

Some of the most dramatic examples of growth are in aging industrial areas near downtown Denver. For example, we’re currently working on the Brighton Boulevard corridor, the spine of an old industrial area that is rapidly transforming into a hip mixed-use arts and tech-oriented district.

Developers in the area are insisting we incorporate bike lanes, broader sidewalks, and stormwater treatment in the right of way. Unlike many older coastal and Midwestern cities, Denver’s not being pressured by the federal government to improve stormwater quality to the degree that these older cities are. Instead, the development community has really been pushing the city to innovate to create green infrastructure systems that also enhance the public realm at a district scale. It’s a very interesting time here, as we re-imagine the infrastructure in those neighborhoods that will be populated primarily by Millennials who don’t want to own a car.

But multiple barriers remain. The city, in partnership with the development community, is trying to identify the appropriate finance and maintenance strategy to transform the area’s infrastructure. The city is trying to catch up with the most innovative of national trends, but they don’t don’t quite know how to do it. Denver isn’t alone in this: Most larger cities are facing the same issues. I only wish we could move more quickly, be more willing to experiment with new ideas, and implement those that prove to be most feasible on a wider basis.

Another of the city’s goals is to make all rivers and creeks swimmable by 2020. How will the city achieve this goal?

All water in Colorado is owned. It’s bought and sold as a commodity, unlike water in wetter climates. There’s an old saying: “in the West, water flows uphill toward money.” Most of the water for front range communities comes from across the Continental Divide through a network of tunnels, canals, rivers. Like most rivers in the West, the South Platte River, which flows through the heart of Denver, serves as an integral part of this network to convey water that has been historically used for agricultural use. During periods of high diversion for agricultural and urban uses, rivers can be literally drained dry.

Until recently, there was no water allocated that would maintain river flows for recreation and habitat. Many rivers in the West face this issue, which will continue to be of concern far into the future because of high demands on water. Coliform, a bacteria; metals; and nutrients are a problem in the South Platte River, as they are in many urban rivers. For multiple reasons, I think the goal of making the cities, rivers, and creeks swimmable by 2020 simply isn’t possible given how we’re approaching the problem today.

It is difficult to remove coliform through passive treatment methods. Meeting that goal may always be a problem because we don’t have a complete understanding of many of the sources yet. That said, there’s a great deal that could be done if there were the political will and funding to tackle it, especially at a watershed or district or neighborhood scale. Because Denver isn’t under a federal consent decree, an improvement in the quality of urban rivers and streams will only occur through public pressure and creative means of financing and maintenance.

What is really interesting is there is significant interest on the part of a growing number of developers to be more responsible stewards of our urban water resources. For example, we are currently working developers, such as Zeppelin Development, Perry/Rose, and Urban Ventures who care deeply about Denver and are saying “We’ve got to do this.” They’re putting political pressure on the city to move beyond traditional stormwater management to employ green infrastructure approaches in a way that is good for business and the environment. Millennials are looking for green infrastructure in their living and working environments.

Denver Housing Authority, another of our long term clients, which has been instrumental in transforming a number of derelict areas the core city, is taking the same approach. As Chris Parr, their director of development, says “We want to be nutty green,” because they believe, as long-term owners of these projects, green approaches to development make good business sense. For example, the redevelopment of an outdated public housing project spanning several blocks at a light rail station very close to the downtown used stormwater infiltration as a primary management strategy to reduce development costs. Significant challenges remain though: Long-standing development standards for stormwater management and street design are still on the books, which limit change.

According to a report published in 2014, Denver is in the top 10 for U.S. cities with the highest percentage of green commercial real estate. Is the city also moving to greener commercial landscapes? If so, can you provide some examples?

We are moving towards more water-conservative landscapes. I wish to make that distinction because Denver Water, the primary regional water supplier, has emphasized water conservation for the last 20 years, resulting in at least a 10 percent reduction in water use. There is an almost universal emphasis on the use of xeriscape principles for commercial landscape design. In 2050, Colorado will have a 163 billion gallon shortage of water available for urban uses, so we’re going to have to explore further means of conservation, as well as rethinking what the larger concept of landscape means in our semi-arid climate.

Because of our water laws, we cannot harvest rainwater. Much of our effluent cannot be reused for the same reasons. That said, there is great potential to transform the urban environment using more regionally appropriate, gray/green landscapes that are more integral with natural processes, which you emerging in Portland and Philadelphia as a result of stormwater mandates.

There are some experimental green roofs here, but they tend to need irrigation because of our solar gain, which is counter to water conservation goals. Because of anticipated shortages, there is talk of “toilet to tap,” but given the vast majority of our domestic supply goes to landscape irrigation, we’ve only begun to explore the possibilities of a sustainable regional landscape aesthetic and ethic.

Our work at Taxi is a good example of a sustainable commercial landscape. We’ve worked within Colorado water law to infiltrate stormwater. We’ve used nonliving materials extensively. The plant palette consists of a broad range of native and non-native xeric plants.

Denver is in the top 10 on the Trust for Public Land’s ParkScore, which ranks cities on the quality of their park systems. What parks best exemplify the city’s commitment to providing high-quality green public spaces?

Denver has one of the more notable City Beautiful-era systems of parks and parkways. It’s on the National Register. Cheesman Park, Washington Park, City Park, and Speer Boulevard are just remarkable historic resources. The system’s been expanded significantly as part of the development of Stapleton and Lowry’s park and open space networks.

In Stapleton and Lowry, the historic Olmstedian park aesthetic has evolved to be much more regionally appropriate, in terms of incorporating large areas of more native and naturalized landscapes driven by managing stormwater on site.

Also, the city is investing heavily in an expansion of parks and natural areas along the Platte River Greenway, which was established over 40 years ago as one of the first greenway systems in the country.

We are currently involved in the $4 million first phase redevelopment of Confluence Park along the river, which is part of a $40 million long-term makeover. Confluence has become overwhelmed with out-of-town visitors and daily users who now live in the Central Platte Valley. We’re looking at public private partnerships to create landscape architecture that better manage conflicts between bikes and pedestrians. There is a level of urban use that demands new types of management and maintenance, something you find in major urban centers but Denver is only beginning to see.

There are some wonderful new parkways, especially in Stapleton, designed around the natural qualities of the West. These naturalized qualities make you feel like you’re in the West rather than in Cleveland or in Washington, D.C. Those parkways have been controversial, but people are getting used to them and see their inherent beauty.

Denver Parks is looking to the future in terms of how we begin to serve our rapidly expanding population, the thousands of new residents who are going to be living downtown. Existing parks in the downtown tend to be oriented to major civic events and festivals. The master plan is proposing an expansion with a range of traditional and nontraditional park types. They seek to incentivize public-private partnerships, which will lead to more private parks in ways that you see in the core of Manhattan — streets as parks, pop-up parks, for example.

Bicycling Magazine ranks Denver 12th in the country for its bicycle infrastructure, behind leaders like New York City, Portland, and even Boulder, which ranks sixth. What are the plans for improving bike infrastructure in the city?

Bike use has gone up dramatically, especially for commuting, over the last 10 years. The U.S. Census Bureau ranked us in the top 10 given some 2.3 percent of residents commute by bike. BCycles, our bike sharing system, has been really successful and expanded beyond the downtown.

There are aggressive proposals for enhancing the cycling network downtown. Our downtown business association is currently crowdsourcing funding to physically separate bike lanes because public funding isn’t currently available. Denver Public Works department has a bicycle coordinator. There’s a major initiative to create a comprehensive system of new bike lanes and sharrows. These all are a testament to the city’s commitment to enhancing our on and off street system for our outdoor-oriented population.

But in spite of all of the improvements, we have some major gaps and barriers in the system and entrenched street standards that aren’t bike friendly. These issues are going to be difficult and expensive to solve.

Why is Denver so keen on adaptive reuse? Many of your projects, such as the Taxi Redevelopment and Northside Park, reimagine old infrastructure to create parks and commercial spaces the city can use today.

In the late 1960s and early 1970s, we lost a tremendous number of fabulous buildings to urban renewal, like most other cities. There was huge resistance, which resulted in the preservation of Larimer Square, the establishment of a number of historic districts, and new landmark status for many remaining buildings. These efforts also spawned Historic Denver and other preservation organizations and programs that have resulted in the preservation of a number of historic districts and buildings: our warehouse district, known as Lower Downtown (LODO), is a prime example. It has been hugely successful as a real estate venture. Although we’ve lost a great number of really valuable resources, today, there is widespread adaptive reuse of warehouses and old industrial buildings.

Taxi was a derelict taxi dispatch center surrounded by rail yards, along the Platte River. Our client, Micky Zeppelin, saw this gritty infrastructure as a place creative individuals wanted to live and work. He’s always been a student of cities around the world. He wanted us to be responsible about water use as part of a much broader agenda of creating a creative community. He wanted a rich environment that was both urban and natural, and one where natural processes could function in the heart of the city.

Northside Park was a decommissioned sewage plant, an incredibly stout infrastructure too expensive to tear down, Our solution to retain the plant was primarily practical. We needed to reduce demolition/construction costs and create space for two soccer fields. Personally, I’ve always been fascinated with layers of history in the land — both visible and invisible — and the richness of expression that is possible by revealing those layers.

Adaptive resuse is messy, but it’s a wonderfully rich way of way of thinking about the world. The world is not a clean and tidy place. The landscapes a lot of us want to live in aren’t necessarily clean and tidy, but they’re vital. They’re alive. This line of thinking can lead us toward the next generation of urban landscapes in the semi-arid West.

William B. Callaway, Noted Bay Area Landscape Architect, Dies – The San Francisco Chronicle, 12/5/14
“His Bay Area work was equally varied, be it Refuge Valley Community Park in Hercules with its gazebo and lake that are a popular backdrop for wedding and quinceañera photographs, or the ascending stacks of triangular granite in the plaza outside the 101 California St. office tower in San Francisco.”

Restoration of Mellon Square Inspires Book About the Modernist LandmarkThe Pittsburgh Post-Gazette, 12/6/14
“As president and founder of The Cultural Landscape Foundation in Washington, D.C., Mr. Birnbaum championed the project because he knew of other significant landscapes that had already disappeared from cities and parks. Six months later, in June 2007, Meg Cheever, president and chief executive officer of the Pittsburgh Parks Conservancy, took Susan Rademacher on a tour of the city’s historic parks — Frick, Schenley, Riverview and Highland — plus the Hill District.”

Presidio Park Project Lands Architect Behind High Line in N.Y. The San Francisco Chronicle, 12/9/14
“The selection of James Corner and his firm Field Operations comes after an unusual competition where five teams were asked to submit conceptual visions for the 13 acres that will blanket two automobile tunnels now under construction. The competition was overseen by the Presidio Trust, which manages nearly all of the 1,491-acre park at the foot of the Golden Gate Bridge.”

Why We Need Horticulturists The Washington Post, 12/10/14
“Horticulture is not a field that attracts enough young people — this is a constant lament of garden directors I meet. For all its imagined bliss, the life of a professional gardener can be hard, stressful, and anything but lucrative. It is a world of insect bites, near-heatstroke, and the steady degeneration of the spinal column.”

FIU Students Seek Flooding Solutions if Sea Level Rises Throughout Miami-Dade CountyThe Miami Herald, 11/20/14
FIU professors Marta Canavés and Marilys Nepomechie worked with students for three years to research sea level rise projections at three, four, and six feet, and created models and proposals to keep existing city infrastructure and neighborhoods habitable. The models, designs and collected data are on display at the new Coral Gables Museum exhibit through March 1.”

S.F.’s Newest Public Space Provides Invitation to Sit, LingerThe San Francisco Chronicle, 11/25/14
“The new plaza is a patch of asphalt at Mission Street, closed to cars but with plenty of room for bicycles to coast through, below a gateway-like frame of salvaged wood adorned with hanging rat tail cactus. Its counterpart at Market Street behind the Palace Hotel spent decades as a deliberate green oasis with formal planters, until it declined to the point where now it is hidden behind construction barriers.”

Parks, Playgrounds Get New Attention in Planned CommunitiesThe Houston Chronicle, 11/26/14

A Guide to Denver’s Best Landscaped Spaces, Deep and FreeThe Denver Post, 11/28/14
“None of it got there by accident, as the new ‘What’s Out There Denver’ online guide reminds us in inviting detail. Our natural places were planned by generations of forward-thinking civic leaders and landscape architects who understood how preserved green spaces balance all of the asphalt and concrete of city life.”

New York’s High Line: Why the Floating Promenade Is So PopularThe Washington Post, 11/30/14
“It has become an archetype for cities everywhere craving their own High Line mojo. In Washington, it is the inspiration for a proposed elevated park where the old 11th Street Bridge crossed the Anacostia River and, separately, for a component in the long-range redevelopment of Union Station.”
