New and non-recyclable materials used in homes and landscapes are often not designed to be recycled. These materials can consume enormous amounts of resources to produce and distribute and create additional waste when they are demolished. Waste materials create waste landscapes: landfills, massive incinerator systems, and multi-square-mile floating plastic garbage islands in the world’s oceans.
ASLA has created a new guide to using low-impact materials at home, which contains research, projects, and resources on how to better source materials for residential landscapes. Developed for homeowners and landscape architects and designers alike, the guide is designed to help spread more sustainable and resilient practices.
Homeowners can also specify local materials to support local economies and cut down on the energy use from the transportation of materials.
But beyond reused, recycled, or local materials, there are other important ways to reduce the impact of materials on our health and environments.
Sustainable residential landscape design can increase the health of environment through the use of innovative low-impact materials that are permeable and reflective (high albedo).
Permeable materials allow water to infiltrate and recharge aquifers, instead of being sent to combined stormwater and sewer systems.
Reflective, “cool,” or white materials help reduce air temperatures, particularly in cities dealing with the challenges of the urban heat island effect, and energy costs by minimizing the use of air conditioning to cool buildings.
There are also more sustainable wood and concrete options out there that minimize consumption of newer materials or extend the life of existing materials.
SITES recommends building with certified, sustainably-harvested woods; recycled woods; and recycled plastic or composite lumber to preserve forests, which are critical to sequestering greenhouse gas (GHG) emissions.
To avoid sending useful materials to the landfill, conserve natural resources, and reduce a project’s carbon footprint, SITES also recommends landscape architects source sustainable concrete from manufacturers using supplementary cementing materials, like fly ash – a byproduct of coal-fired power plants. Landscape architects should reuse concrete from structures on the existing site, like crushed concrete as an aggregate base. Concrete that incorporates recycled materials, like crushed glass or wood chips, are a more sustainable and use less cement than traditional pavers.
Used in both landscapes and buildings, low-impact materials can reduce GHG emissions and create a healthier environment.
Local governments can partner with non-profit organizations and landscape architects and designers to increase public awareness about why it’s important to use low-impact materials.

The book, written with Douglas Brenner, begins with Hoerr’s first residential project, a garden in Lake Forest, Illinois, a suburb north of Chicago.
And then moves to bustling plazas and civic spaces, like the Michigan Avenue streetscape in Chicago, recipient of the 2016 ASLA Landmark Award, which is given to projects of longevity that have maintained their design integrity and contributed to the public realm.
In 1991, then-Chicago Mayor Richard Daley tapped Hoerr and Gordon Segal, founder of Crate & Barrel, to redesign the landscape of Michigan Avenue, a hotspot for tourism amid Chicago’s towering skyline. Hoerr’s goal was to “make the horticulture so bold that it looked ready to jump out of the planters and compete with any skyscraper.”
Schaudt also renovated Daley Plaza, a much-loved iconic square in Chicago. Designed by Jacques Brownson in 1965, Schaudt called the Modernist space “‘the Italian piazza of Chicago.'”
Schaudt sought to “replace the thin stone pavers with more durable lookalikes, double the tree court without changing the number or location of planters, and leave the plaza’s landmark character intact.”
A charming moment is documented in the book: “After Daley Plaza reopened, a Chicago architect confided, ‘This looks great, Peter, but I can’t figure out what you did.’ Schaudt took the comment as the highest compliment to his craft.”
It’s these bits of personal context that make Movement and Meaning compelling.
The book offers insight into design challenges and decisions, explaining the unique circumstances under which each project came to be.
Take the Greater Des Monies Botanical Garden. Brenner explains that since its heyday in 1979, the site around the garden fell into disrepair. Visitors struggled to find comfort in the landscape surrounded by an interstate and a double-lane parkway. After joining a design committee in 2004, Hoerr concluded the design should be based on water and sought to bring the river to the botanical dome.
In the Dwarf Conifer Garden, another Midwest plant-focused space, the studio increased accessibility and conducted a “plant-by-plant assessment of the two-decade-old garden.”
Green Roofs Are Getting a Big Trial in Hoboken– Next City, 8/18/17
“The movement toward green building and sustainability-minded development is at an odd crossroads. On one hand, some progressive cities have made regulation strides toward more energy-efficient and less environmentally harmful building practices, while a viable industry has grown up around green construction and roofing materials.”
The Pre-Oscar Snub– The Huffington Post, 8/23/17
“Well, it’s not Oscar season but we already have one of the biggest snubs of the year. It’s pioneering Modernist landscape architect Dan Kiley in the recent motion picture Columbus.”
‘Project Birdland’ Transforms Francis Scott Key Elementary/Middle School– The Baltimore Sun, 8/27/17
“School doesn’t start for another week, but 6-year-old Kyle Schuller spent Sunday afternoon running around in front of Francis Scott Key Elementary/Middle School. The soon-to-be first-grader watered some freshly planted shrubs in a “habitat lab” that will soon welcome him and other students to school each day.”
Burial mounds from 1,500 years ago seem like an unlikely inspiration for CoFuFun, a contemporary plaza and playground, but Japanese designers with Nendo found a way to translate the spiral forms of an ancient Kofun into a place that encourages joyful exploration in Tenri, a small city in Nara prefecture.
The 6,000-square-meter (64,000-square-feet) plaza next to a train station includes a meeting space, events stage, playground, information kiosk, and cafe and shops. According to Nendo, which outlined their project in ArchDaily, the goal is to “encourage community revitalization” by creating a hub for both tourists visiting and locals commuting.
Tenri has a number of ancient Kofun, which are “beautiful and unmistakable, but blend into the spaces of everyday life in the city.”
Nendo placed Kofun-inspired forms throughout the plaza landscape, which is itself modeled after the Nara basin in which Tenri sits, a space surrounded by mountains. Here, the Kofun are bright-white, a color that symbolizes purity and truth, but is also associated with mourning.
Kofun are key-shaped mounds with levels, like the ancient zigurrats of Mesopotamia or the step pyramids of the Maya. Using the terraced Kofun as a model, Nendo used the forms to create stairs, benches, fences, roofs, and shelves.
The designers ingeniously incorporate activities into the Kofun forms: one convex center enables kids to run around in circles until they are dizzy while protected by a fence; one provides the foundation for a giant trampoline; and the interior of another hosts the cafe and shop.
The plaza creates a sense of flow for visitors who can move seamlessly from one use to another. This is because it’s “an ‘ambiguous’ space that’s a cafe, playground, and massive piece of furniture all at once.”
The plaza name — CoFuFun — incorporates “fufun,” which in Japanese means “happy, unconscious humming.” Co-” refers to cooperation and community. The name works in both Japanese and English. Hopefully, they can find a way to keep the white forms bright.
Plants are central to a functioning global ecosystem. Plants oxygenate the atmosphere and reduce atmospheric pollutants. Ecological restoration in both developed and developing countries is a primary strategy for mitigating the impacts of climate change. Native plant communities are not only key to the global ecosystem, but also crucial to environmental and human health at the residential and neighborhood scales.
Urbanization has fragmented what were ecologically-productive landscapes. According to the Audubon Society, the continental U.S. has lost 150 million acres of wildlife habitat and farmland to urban sprawl over the last century. Sustainable residential landscape architecture practices can help build a network of productive landscapes. Native plants can be used to regenerate sustainable plant communities and reconnect fragmented ecosystems in residential areas. Creating a network of productive ecosystems expands wildlife habitat areas and boosts human health and well-being by bringing nature’s benefits right to residential yards and outdoor spaces.
ASLA has created a new guide to applying ecological design at home, which contains research, projects, and resources on residential landscapes. Developed for homeowners and landscape architects and designers alike, the guide is designed to help spread more sustainable and resilient practices.
Homeowners can use native plants to reduce the use of excess water, energy, and chemical fertilizers and pesticides that damage natural ecosystems, as well as support pollinators.
Residential landscapes can also be used to grow food at home and in communities. When growing food, gardeners should apply principles of ecological design and permacultural practices to ensure food production and garden systems are integrated with the natural environment and avoid contaminating local watersheds with runoff. Homeowners and communities can create composting systems for efficient waste removal and to increase organic matter in the soil.
And plants can also be used inside the home to improve air quality and human productivity.
Homeowners should be mindful of the quality of the soil on their property. Healthy soils are essential to plant and tree health and enable the infiltration of stormwater into the ground. Years of development and construction can lead to layers of compacted soil that restrict movement of water and air, and limit root growth. Homeowners can achieve credit from The Sustainable Sites Initiative™ (SITES®) by using techniques like subsoiling and adding soil amendments to help rebuild ecological function in soils.
Landscape architects partner with communities, non-profit organizations, and local governments to increase public awareness about using sustainable residential design practices that yield productive plant systems and reduce the negative ecological impacts of typical residential development.
Amid the global outcry over President Trump’s remarks that sought to legitimize white supremacists at a press conference earlier this week, we almost missed the fact that Trump rolled-back Obama administration rules to improve the resilience of federally-financed buildings and infrastructure in flood-prone areas and to update important flood risk management standards. In 2015, President Obama required new infrastructure to be built two feet above the 100 year flood plain and three feet for critical infrastructure like hospitals and evacuation centers, and also updated standards that guide flood insurance rates. Beyond undoing these regulatory actions, President Trump announced a new effort to streamline environmental review processes for new infrastructure projects.
The Federal Emergency Management Agency (FEMA) estimates flooding has caused some $260 billion in damages from 1980 to 2013. And in the past decade, flood insurance claims now total $1.6 billion annually, putting further pressure on the already deeply-indebted flood insurance system. As climate change increases both inland flooding and coastal sea level rise, scientists expect flooding to only worsen.
To address increased risks, the Obama administration required federally-financed projects to factor in climate change projections. Now, with a stroke of a pen, the Trump administration has not only put communities at greater risk, but likely reduced the lifespan of infrastructure in flood-prone areas, and their financial efficiency and effectiveness as well.
Former FEMA official Rafael Lemaitre, told Reuters the Obama-era rules were “‘the most significant action taken in a generation’ to safeguard U.S. infrastructure. ‘Eliminating this requirement is self-defeating; we can either build smarter now, or put taxpayers on the hook to pay exponentially more when it floods. And it will.'”
And in New Jersey, which was hard hit by Hurricane Sandy, there was disbelief. John Miller, New Jersey Association of Flood Plain Management, told NJ Spotlight the Obama-era rule was a “solid idea.” He added: “We are going to have worsening conditions. We have to build to future conditions.’’
According to Reuters, both the American Petroleum Institute and the National Association of Home Builders praised the move to roll-back the flood risk management standards to the earlier version established by President Carter in 1977, arguing that the Obama-era rules on managing flood risk increased housing costs.
The Obama administration stated that the new standards would only raise housing costs by 0.25 to 1.25 percent, but Republican Congressman Ralph Abraham, from Louisiana, who sponsored legislation that would have blocked Obama’s flood standard, told The New York Timesthe new rules “would have increased the cost of a new home in Louisiana by 25 percent to 30 percent, because most of the state would be put in a federal flood plain.” The overall effect, however, may be to increase risk, as communities continue to live and build in flood plains not be characterized as risky, and then fail to qualify for federal assistance when disaster invariably strikes.
In a new fact sheet on infrastructure that lays of the Trump administration’s vision for investing $200 billion in the 2018 budget, Trump administration officials took aim at what they describe as onerous environmental review processes for infrastructure projects. “The environmental review and permitting process in the United States is fragmented, inefficient, and unpredictable. Existing statutes have important and laudable objectives, but the lack of cohesiveness in their execution make the delivery of infrastructure projects more costly, unpredictable, and time-consuming, all while adding little environmental protection.”
At his shocking press conference, Trump said a complex highway project can take up to 17 years (but didn’t cite an actual example of this). He called the current approach a “disgrace.” His goal is to reduce environmental reviews for a project to two years and centralize management through a “one Federal review” in which one government agency takes the lead on a project.
Trump said: “It’s going to be quick. It’s going to be a very streamlined process. And by the way, if [a project] doesn’t meet environmental safeguards, we’re not going to approve it — very simple.”
According to BloombergPolitics, the new order “allows the Office of Management and Budget to establish goals for environmental reviews and permitting of infrastructure projects and then track their progress — with automatic elevation to senior agency officials when deadlines are missed or extended. The order calls for tracking the time and costs of conducting environmental reviews and making permitting decisions, and it allows the budget office to consider penalties for agencies that fail to meet established milestones.”
Environmental groups were uniformly opposed to the effort to streamline federal environmental reviews, arguing that a two-year time frame may result in more wasteful and risky projects with damaging environmental impacts.
Republicans argue that excessive regulations are holding up infrastructure projects, while Democrats may agree that some regulations could be streamlined, but, really, the primary issue is there isn’t enough public investment. ABC News reports that a Treasury Department report released earlier this year found “a lack of public funding is by far the most common factor hindering completion” of infrastructure projects.
In other federal environmental and climate news: Scientists from 13 federal agencies released a draft of the National Climate Assessment, which Congress mandates be updated every four years. The New York Times writes: “The study examines every corner of the United States and finds that all of it was touched by climate change. The average annual temperature in the United States will continue to rise, the authors write, making recent record-setting years ‘relatively common’ in the near future.” Perhaps the best that can be hoped for with this administration is the draft review process will be allowed to continue on auto-pilot without political interference.
At the department of interior, The Nation writes, a purge of climate experts is underway, while the word “climate” is being scrubbed from program titles.
And at the Environmental Protection Agency (EPA): the agency is now implementing national ambient air quality standards, rules created by the Obama administration in 2015, after 15 states and a number of leading organizations sued. Still, there are other worrying developments: Administrator Scott Pruitt’s agenda to reduce regulations and cut staff is largely happening in secret. But that may change: the California attorney general just sued the EPA in attempt to force them to explain how Pruitt will handle conflicts of interest with the fossil fuel industry.

Any residential landscape can be designed to both conserve water in times of water scarcity and reduce flooding during storms. Homeowners can use green infrastructure approaches, like bioswales and bioretention ponds; rain gardens; rain water harvesting; water recycling; and drip irrigation to more sustainably manage water.
The Federal Emergency Management Agency (FEMA) estimates flooding has caused some $260 billion in damages from 1980 to 2013. And in the past decade, flood insurance claims now total $1.6 billion annually, putting further pressure on the already deeply-indebted flood insurance system. Sustainable landscape architecture practices — including green infrastructure — can significantly reduce the impacts of flooding on residences.
Homeowners also waste water by irrigating their lawns with water that should be reserved for human consumption. According to the Environmental Protection Agency (EPA), nearly 9 billion gallons of water is used for residential outdoor water use, mainly for landscape irrigation, some 30 percent of total residential water use.
Sustainable residential landscape architecture—if part of an integrated site design, a comprehensive approach to sustainable building and site design—can dramatically reduce water usage while creating a healthy residential environment.
Homeowners can promote the infiltration, storing, and recycling of water, and limit the use of valuable potable water for landscapes. Bioswales / bioretention ponds, rainwater gardens, and local sustainable water recycling and drip irrigation systems can all be used to efficiently manage water. Homeowners can recycle and reuse greywater (and even blackwater) for landscape maintenance, car washing, and toilet flushing.
It’s important to note that degraded and compacted soil will reduce water and air infiltration into the ground. Homeowners can maximize the benefits of natural stormwater systems by improving the quality of soil on their property though remediation techniques.
Homes that include natural green infrastructure not only better manage stormwater runoff, but also reduce the massive energy costs associated with running complex water management systems. Water and waste utilities are heavy users of energy and major producers of greenhouse gas emissions.
