Not Too Mulch to Ask

It was a simple ask. Our Chicago First Ward Alderman, Daniel La Spata, included a notice in his e-newsletter about a Saturday morning outing, organizing at his ward office on Milwaukee Avenue, for volunteers to join Openlands Chicago tree keepers to help place mulch around street trees nearby on Armitage and Milwaukee Avenues, and just, well, clean up a bit.

I admit to being an easy sell on urban trees. There is a beautiful century-old American elm in our backyard. Nearly fifteen years ago, I led an American Planning Association project, funded by the U.S. Forest Service, that resulted in a report called Planning the Urban Forest. It’s not that I believe the right trees in the right places improve the livability of our neighborhoods; I know it because of extensive research over many years that I have digested from numerous sources that prove it. I have written about it in published articles.

So, once in a while, I try to put my muscle and time where my mouth is and just get out and do the real thing. All I had to do was register online so that Openlands knew how many people would participate. Besides, working to improve the survivability of real trees in a street-side environment is always an opportunity to learn something. Add my proclivity as a compulsive extrovert, loving the chance to meet and talk to new people, and I was sold. La Spata seemed pleasantly surprised when I showed up just before 9 a.m., but he shouldn’t have been. This is fun stuff for me.

But first, a word about Openlands, the organization with which he allied to provide this volunteer service opportunity. Openlands is now entering its seventh decade as a regional conservation organization, having been launched in 1963. They have consistently offered a regional vision for a landscape of land and water trails, urban forests, and public gardens, all with an eye to enhancing access for city residents. Together with the Morton Arboretum, based in Lisle, Illinois, they have provided a strong voice for the value of open space and trees in the metropolitan area that have kept people aware of the opportunities for a healthier and more biodiverse environment. While I have not been directly involved in Openlands, I have served for several years on an advisory board for Morton Arboretum’s Chicago Regional Trees Initiative, which has produced model ordinances and programs for communities throughout the region. I highly recommend visiting either or both websites and learning more about their programs in this time when climate change is threatening our urban quality of life.

But back to the scene of the volunteer work. More than a dozen volunteers, many of them certified Tree Keepers for Openlands, showed up. We initially were briefed on the day’s activities, including the areas where we would be working. We would not be planting trees—that is up to the city when it comes to street trees. Nor would we be pruning, which must be done by professional arborists. But we would be working with someone from the Chicago Streets and Sanitation Department, which provided a city truck to pick up any debris we picked up, or garbage, such as empty mulch bags, that the operation generated. Mostly, we used mulch to fill in boxes around street trees, not overloading the site but enough to protect the trees.

We also dug up and removed some burlap bags that contractors had left around some street trees, in order to allow them to grow and breathe better. That was not always easy because they become buried in the compacted soil, making them hard to extract and remove. Aside from personal fitness, I sometimes wondered what other benefits came from my twice-weekly strength and cardio workouts at a local gym. Now, I realized I was well trained to provide the powerful yank that some of these bags needed to pull them out of muddy soil for disposal. Fitness can serve practical purposes.

We were also fortunate that the weather was perfect for the occasion. The high temperature was in the low to mid 70s that day, so the only time I sweated a bit was when, on one occasion, I had to labor extra hard to remove one of those burlap bags. It was sunny but bearable. I had forgotten my sunglasses, but really did not need them.

Toward the end, as our crew had worked its way northwest on one side of Milwaukee Avenue and then back down the other toward the ward office, we were adding mulch in front of a relatively new nonprofit used bookstore, Open Books. If there is one diversion that can get my attention in addition to trees, it is browsing a bookstore, where some trees find a new but lasting use. I also needed to use the bathroom, so I asked the clerk at the checkout desk. On the way back, I mentioned that, on her birthday a few days earlier, my wife and I saw Oppenheimer at a movie theater before getting dinner nearby. Did the store have copies of American Prometheus, the Kai Bird book that inspired the movie? She looked, and they did, and I walked out with a used copy for a little over $13. Combining that with improving the neighborhood environment made for a successful morning, I felt.

But soon, as noon approached, we had a debriefing on what we had accomplished and any useful suggestions from volunteers. I suggested making wire cutters available because we had encountered chicken wire in some of the tree boxes, something much more problematic than burlap boxes, which eventually biodegrade. I don’t recall what else was mentioned, but our crew leader took notes.

Next to the aldermanic office was an outlet for Jersey Mike’s. I had joked that we should all walk in and tell them we had heard that they were planning to feed the volunteers. We laughed but obviously did no such thing. But the thought of a good sandwich burrowed into my brain, and with less than half a mile to walk home, I entered the store and ordered a turkey sandwich, Mike’s way, and took my prize home for lunch, accompanied by Cheetos and a chocolate chip cookie. The sandwich was the only likely source of nutrition, I suspect, but along with some lemonade from the refrigerator, it felt like an adequate reward for making a small difference in a big city.

Catch Up and Slow Down

I was lying half awake in bed at 4 a.m., unable to return completely to sleep after using the bathroom. My mind kept rolling over various competing obligations and necessities, and the thought hit me:

“You must catch up while slowing down.”

Frankly, that made about as much sense to me in the moment as it probably does to you upon reading it. One’s subconscious mind can shed strange light sometimes. The whole idea is as paradoxical as it is imperative. And yet, I mention it because I strongly suspect that many people can relate to it at some level.

We get caught in situations. Mine is partial explanation of why it has been weeks since I last posted on this blog, but that is a minor measure of the overall impact of a combined events and circumstances. As a professional urban planner, I can state flatly that life does not always follow our plans. It springs surprises and throws nasty curveballs.

Work piles up, even if much of it, in my case at the moment, is pro bono or volunteer work. The thought that I am sharing occurred last weekend, and I wrote the first four paragraphs above that morning. I got sidetracked until now, but there’s no better time to finish a blog post than now–I guess.

Let’s go back almost two months. On April Fool’s Day, aka April 1, I flew with my wife (Jean) and a teenage grandson (Alex) to Philadelphia to attend the American Planning Association’s National Planning Conference. This was important to me on several levels, including my role as immediate past chair of the APA Hazard Mitigation and Disaster Recovery Planning Division, which keeps me on the Executive Committee until the end of this year. Even then, I will still be involved, primarily in charge of a documentary film project, but I will save that topic for my next blog post. You can see the work piling up already. Being there allowed me to network with numerous people about numerous issues and projects and attend our division reception, where we announced a fundraising campaign to support the film project. Over breakfast, it gave one colleague from APA’s International Division an opportunity to recruit me for its Ukraine Rebuilding Action Group. But it was also a chance, during spring break for the Chicago Public Schools, to tour parts of a historic city with Alex and Jean.

A much earlier request to speak at a conference in Georgia set me up to fly back to Chicago on April 4 to stay overnight and fly the very next day to Atlanta. The occasion was the Larry Larson Speaker Series of the ASFPM Foundation at Lake Lanier, attached to the annual conference of the Georgia Association of Floodplain Management. Our distinguished panel was addressing issues of disaster resilience from federal, state, nonprofit, and local planning perspectives.

Little did I know my own resilience was to be tested. Wicked weather sweeping through the Midwest and South that week created havoc. By the time I arrived at O’Hare International Airport, having neglected to check for cell phone text messages, I learned that my flight to Atlanta was canceled and no others were available that day. I needed to be at Lake Lanier by that evening, so I conferred with the event organizers. I had to cancel my flight and hotel room and ended up speaking the next morning by video connection, missing out on personal interactions but delivering my comments anyway. Perhaps my own most notable remark was that I no longer wanted to hear any local official say after a natural disaster that “no one could have foreseen” the event. If the event happened, I said, it was always within the realm of possibility. “What you’re telling me,” I said, “is that you may not have spent much time thinking about it beforehand.” Terri L. Turner, a long-time colleague and recently retired development services administrator for the city of Augusta, Georgia, told me later that there was a ripple of laughter in the audience after I said that. Floodplain managers too often know the truth of such assertions.

Within two weeks, I discovered that my personal resilience was to be challenged in more significant ways. By mid-April, I experienced a sudden problem on the bottom of my left foot that appeared to be some sort of lesion or blister. Not sure, the best move seemed to be a consultation with my primary care physician to see what he thought. That happened on April 19, but he was also uncertain and referred me to a podiatrist. However, the very next morning, I reported to Northwestern Memorial Hospital for a previously scheduled prostate biopsy, which produced its own complications over the weekend. I might have just waited those out restfully if I had not been scheduled as co-instructor for a week-long online, all-day FEMA class that week, which was largely an exhausting experience. In mid-week, I left right after class adjourned for a follow-up appointment with the urologist to learn the results of the biopsy, which were reassuring but will involve some further measures this summer.

I finally managed to see the podiatrist the following Monday. He determined a need to biopsy the growth, a decidedly painful and messy experience even with a local anesthetic. I went home with a bandaged foot that I needed to protect for several days until it healed. A week later, however, I learned that the growth was benign; surgery would still be beneficial though not urgent.

Somewhere, in between all this, my printer died. I bought a new one from Best Buy but asked that the Geek Squad do me the favor of installing it. After all, I bought it the day of the foot biopsy. Our aging electric mower also died, and I brought our 19-year-old college student grandson to Home Depot to help buy a new one. I let him assemble it and mow the yard. I’m fine with mowing now, but for a few days, it was decidedly not a good idea.

By now, the second week of May had arrived, and a number of commitments beyond the FEMA class were amassing a backlog of work for which I needed a rapid rise in stamina, which I have mostly managed to generate. Nonetheless, I wish I had more energy and more hours in the day. That does not even speak to family obligations as summer arrives and school ends, and I dream of a vacation while arranging to see doctors in August. I’ll figure it all out, but as I said, life throws curveballs. The value of being 73 is that one has presumably learned something about how to handle matters more efficiently and wisely. I am applying that wisdom to regain control over those pending tasks and establish priorities. I am learning how to catch up and slow down at the same time.

My next post, coming very soon, will share the biggest project currently on my plate. I hope you will find it as fascinating and exciting as I do. Resilience matters.

New Year’s Thought about Legacy

I am a tree lover, but not a tree hugger. I think there is a difference, although I do not wish to demean tree huggers in any way. I am simply coming from a different place, viewing matters through a different lens.

I can understand the emotional response that trees elicit from huggers. I appreciate the beauty that nature provides and feel moved upon seeing a forest or even the single American elm that towers over our backyard. I had already assumed that this tree, which we protected when we built our home in 1994 by adjusting the location of the garage and shortening its apron into the alley behind us, was at least a century oldwhen an arborist from Davey Tree, which prunes it periodically, confirmed my guess. At its ripe but healthy old age, it has watched many of us humans move in and out of the neighborhood and seen houses built and torn down. It has survived a dozen serious blizzards and major windstorms, such as the August 2020 derecho that brought 100-mph winds and two tornadoes to the city of Chicago. Having turned 73 just before Christmas, I can anticipate the possibility that the tree may yet outlive me. I hope it does; I would hate to have the responsibility of tearing it out if it dies.

Davey Tree at work on our American elm tree

But a great deal of my admiration for trees is intellectual and analytical. As an urban planner, I have come to appreciate their role in the city. I led a project for the American Planning Association (APA), published in 2009, that examined in depth how planners could prioritize the role of trees in helping us all build prosperous, beautiful, and environmentally healthy communities. As with any serious research project, I learned much from piloting that effort. I gained some in-depth knowledge of the various ways in which trees filter air and water pollution, reduce stormwater runoff and hence flooding, enhance property values, and temper human aggression, among other benefits to human society. We are fools when we think we can live without trees. Their presence helps humanize us.

I will not regurgitate here all the data that are available to confirm these statements. You can start just by downloading Planning the Urban Forest. I am making a point about my own perspective, which is built heavily upon science while honoring my own environmental instincts, which run deep. Half a century ago, I led the first student environmental organization at Cleveland State University. Instincts and intellectual curiosity often work together.

What prompted this reflection was a recent article from the New York Times. It actually concerned the gradual changes that have transformed a Parisian cemetery, Pere-Lachaise, opened in 1804. It houses, if that is the right verb, the remains of numerous artists and authors including Marcel Proust, Frédéric Chopin, and Oscar Wilde, or if you prefer more modern and volatile types, Jim Morrison of The Doors. Once tended like a golf course, it underwent a transformation after a city directive in 2011 encouraged cemeteries to stop using herbicides. In just a decade, nature has reclaimed much of Pere-Lachaise. Trees have grown, the canopy shades the grounds, birds nest in the trees, and the corpses in coffins share the land with the squirrels and foxes. A funny thing happened on the way to this green restoration: The cemetery became significantly more popular with people. Visitors now total more than 3 million per year. Nature and people are learning to live together.

There is a religious element that appeals to me as a Lutheran. Martin Luther himself was a mixed bag in many ways. He did not always know when to pause and think before he wrote, but there are numerous pearls of wisdom that persist nonetheless, aside from his theological disputations.

About 12 years ago, I believe, I was invited to speak at the annual conference of the Mississippi Chapter of APA—not once but twice. The first presentation involved contentious issues of hard-core planning, focused on hazard mitigation. The location, Ocean Springs, sits on the Mississippi Gulf Coast, which had experienced the worst storm surges of Hurricane Katrina in 2005. It was the second presentation that I found more inspirational because it focused on the then recently released APA report on urban forestry. During the audience questions, there was some inquiry about motivation for advancing the subject matter. Instead of offering a scholarly response, I offered my religious affiliation as an excuse for quoting Luther. When asked once what he would do if he knew the world would end tomorrow, he is reputed to have replied simply that he would “plant a tree.” That sort of defiant commitment to hope, and the recognition that trees are a potent symbol of hope, I said, was what motivated me. It is what truly makes us human.

I want to make two things clear as this new year begins and I edge ever closer to an eventual and inevitable demise. First, I have left instructions for my cremation because, in the 21st century and devoid of any superstitions about how our remains are handled, I wish not to occupy any real estate after I die. I do not need to take up space in in a local cemetery. God will decide what to do with my spirit. Second, however, I do want my successors and friends to take time during or after a memorial service to plant a tree.

Please, just plant a tree and say a simple prayer. No more powerful message is needed. Trees will speak for themselves.

Truly Hard Wind

What in the U.S. Midwest would spur comparisons to a hurricane? What could spread damage over an equally wide area? It is a good bet that most people are unfamiliar with the word “derecho,” which comes from Spanish, meaning “straight,” but such a storm made itself felt just three weeks ago in Iowa, Illinois, and Indiana, as well as parts of Nebraska and Wisconsin. The Spanish word with an adopted meaning in English refers to such a storm’s powerful straight-line winds, as opposed to another adapted Spanish word, “tornado,” literally meaning “turned,” which, of course, refers to a cyclonic, or spinning, meteorological phenomenon.

The Event

On August 10, a derecho took shape in eastern Nebraska and the southeastern corner of South Dakota early in the morning. The city of Omaha suffered some of the initial damage, with an estimated 57,000 people losing power. But as it roared across the center of Iowa, the storm, as derechos often do, rapidly gained wind speed until estimated winds of 140 miles per hour struck Cedar Rapids and surrounding Linn County in eastern Iowa. Nearby Iowa City, home of the University of Iowa, also suffered extensive damage. Derechos can and typically do strike with little warning, unlike hurricanes, but even at speeds of 90 to 100 mph, in this case, it still takes hours to cross Iowa from west to east, and even longer to reach Illinois and Indiana.

Thus, my first warning of what was to come, sitting here in Chicago, was a telephone alert from the University of Iowa around noon that day. I get such alerts because I am on the faculty, although I now teach remotely as an adjunct. But our landline and my cell phone are on the system, so the alerts come automatically. Fortunately, that gave me most of the afternoon to prepare for what was coming, which arrived in our area around 3:45 p.m. Winds and rain pounded on our skylights for nearly 45 minutes, leaving numerous branches and twigs on the ground from our stately American elm, which towers above our house and garage and has probably withstood other storms for at least a century. It was already huge when we built our house in 1994, and we chose to make it sure it remained. Even this storm caused it only minor damage.

The same could not be said of many street trees in parts of Chicago. Trees often collapsed on top of parked cars, leaving many owners to bemoan what became of their vehicles—or, in some cases, the roofs of their homes.

Even the repose of the dead was not left undisturbed. Graceland Cemetery, one of the more famous in Chicago, faces months of repairs and replanting and is closed for six weeks. The storm uprooted about 40 trees and damaged numerous gravestones and monuments. It had become a popular place for peaceful strolls and contemplation during the months of coronavirus-induced shutdown. After the storm, it was a visual mess that will cost about $250,000 to repair.

Removing damaged trees in Chicago’s Rogers Park.

One lesser-known by-product of derechos is tornadoes, which can be spun off from the shelf cloud as it moves through an area. In Chicago, two tornadoes, one EF-1 in the Rogers Park neighborhood along Lake Michigan near the city line with Evanston, literally buzzsawed trees in an area of densely built multifamily housing and small

businesses. A few days later, I visited the area to shoot photos that appear here. At first, driving up Greenwood Avenue, I wondered where the damage was. But as I drove further north and approached W. Jarvis Ave., the answer became starkly obvious. I could not drive beyond that corner because the street was blocked; Jarvis was one way going east, but Jarvis east of Greenwood was also blocked. City trucks were removing damaged trees. After finding a way to park without impeding traffic, I encountered insurance agents on the ground shooting outside photos of nearby buildings, presumably for damaged masonry. Any damaged cars had already been removed.

That tornado, and another that reportedly skipped across the Eisenhower Expressway (I-290) on the West Side, dramatically demolished for some an old urban myth that tornadoes don’t strike urban areas. People believe this for various reasons, including how they think tall buildings disrupt wind circulation, but trust me: I’ve been involved in disaster recovery long enough to know that tornadoes do not discriminate against smaller towns. Rogers Park is very urban. Tornadoes go where they please. This specific tornado eventually skipped out over the lake, becoming a waterspout. But it left its mark.

The storm, by the way, ultimately spun off at least 17 documented tornadoes, mostly in northern Illinois, but a few in Wisconsin and Indiana. All were either EF-1 or EF-0 on the Enhanced Fujita scale. But by far, most of the damage resulted from the straight-line winds themselves, which were often in the range of 90 to 100 mph, with a top measured speed of 126 mph in Atkins, Iowa, making them basically of tornado or hurricane strength. And they sped, over the course of a single afternoon, across all or parts of several states.

By 4:30, the storm had continued its march into northwest Indiana, where it finally petered out. But what happened along the way?

Iowans can attest that it functioned across much of their state like a Category 2, maybe even Category 3, hurricane. Lyz Lenz, a columnist for the Cedar Rapids Gazette, noted in a guest column for the Washington Post four days later that the winds had damaged “more than 10 million acres, or 43 percent, of the state’s corn and soybean crop.” The reduction in harvest in Iowa is likely to be between one-fourth and one-half. The heading on her column referred to the storm as an “inland hurricane” that most people had not heard about. The damage was massive enough to be visible in satellite images.

The damage was not just to crops on the ground, but to hundreds of millions of bushels in storage bins on farms and in commercial storage facilities, according to the Iowa Department of Agriculture. Toppled grain bins were a common site.

Despite those staggering figures, that was only the beginning. Between Indiana and Iowa, four people died from either falling trees or electrocution, and, in one case, a mobile home tipped over by high winds. Losses of electric power affected approximately 585,000 Iowans, or roughly 20 percent, while 1.9 million lost power in neighboring Illinois. Tree damage in Linn County totaled in the hundreds of thousands, and most buildings suffered anywhere from mild to catastrophic damage. In small towns, like Grinnell, building damage and tree damage to cars was also extensive. Here, I wish to thank Rachel Bly, director of Conference Operations and Events for Grinnell College, for sending me dozens of photographs she shot after the event. Bly, I might note, has a certificate in emergency management from Park University in addition to her MPA from Drake University. The images she shared help convey some reality to the trauma that occurred. Hundreds of other small communities suffered similar impacts. Not surprisingly, Gov. Kim Reynolds issued a state disaster declaration by August 14 for 25 counties, and has sought a federal declaration from President Trump, citing an estimated $4 billion in damages. By August 19, Trump had signed a declaration for Public Assistance (PA) but not Individual Assistance (IA) for Iowa. PA provides aid for restoring public infrastructure, such as roads and bridges and community facilities, while IA provides direct aid to individuals for reasons such as loss of housing.

Derechos as a Natural Hazard

All this raises the question of what we know about derechos as a wind-related hazard. I will confess that I spent most of my life never having heard the word, let alone understanding what it meant. It is not the most common occurrence, but it certainly ranks among the most destructive. To my surprise, I learned from Wikipedia that the term was coined in 1888 by a German-American scientist, Gustavus Detlef Hinrichs, who had emigrated to St. Louis just before the Civil War. He wrote in the American Meteorological Journal about a storm that struck Iowa in 1877 and described its unique characteristics. Nonetheless, even in the Midwest today, many people are unfamiliar with the term—until they hear it on the news, as they did on August 10 amid storm warnings.

There are several types of derechos, but the National Weather Service describes a derecho as a “widespread, long-lived windstorm that is associated with a band of rapidly moving showers as thunderstorms.” More specifically, it defines the phenomenon as a swath of damage that “extends more than 240 miles (about 400 kilometers) and includes wind gusts of at least 58 mph (93 km/h) or greater along most of its length.” In plain English, this is a huge, regional storm, not some localized thunderstorm. It exhibits straight-line winds that can be at least double the minimum in the definition, and the August 10 event involved winds far above 58 mph in most locations. Like all such storms, it is a product of unstable atmospheric systems, in this case typically involving a bow-shaped front in a large squall line.

The storms are typically a mid-latitude phenomenon, making North America and the Midwestern U.S. particularly susceptible, but they occur elsewhere in the world as well, including southern latitudes (southeastern Brazil and Argentina), South Africa, China, and even eastern Europe, where a derecho struck parts of Estonia in August 2010, and near Berlin in Germany in 2002. The August 10 event was not the first one I have witnessed in Chicago—another struck in July 2011 and disabled electric power for nearly a million people—but it was certainly the largest in a long time.

70% of all derechos occur between the months of May-August (the warm season). The other 30% occur during the cool season. From National Weather Service website.

As a mitigation planning response, almost no hazard mitigation plan (produced for FEMA approval as a condition of eligibility for federal hazard mitigation grants) for any state or community east of the Rockies (with the possible exception of Florida) should fail to identify derechos as a potential hazard. Moreover, especially in the Midwest, it may be time for states and communities to reexamine their building codes for wind resistance as a means of limiting future damages from derechos. Finally, it may also be time for many communities to examine more closely their urban forestry programs for adequate attention to hazardous tree management. That does not mean refusing to plant trees or removing them unnecessarily as a mindless precaution. It does mean engaging professional urban foresters in an assessment of the urban tree canopy with an eye to ensuring forest health and removing those trees that are most likely to fail under severe wind pressure. Already, the call has arisen for such reforms in Chicago. It is time for planners, environmentalists, disaster professionals, open space advocates, and concerned citizens to seize the moment while they have the public’s attention.

Hurricane Harvey Interview on CBC

For those who have been reading the posts I have recently done since Hurricane Harvey made landfall, I thought it might be of interest to see this video clip of an interview I did with Canadian Broadcasting Corp. two days ago: https://youtu.be/UFslrKPd04s

Regional Green Infrastructure

The subtitle to this headline for many people might be: Who Cares? As a term of art, green infrastructure may be popular with landscape architects, civil engineers, and urban planners, among a few other allied professions, but it does not often mean much to the average person. Many people may struggle to define infrastructure even without the word green in front of it.

Infrastructure generally refers to those modern systems, such as roads, bridges, and utility grids that allow our cities and regions to function effectively. Recognizing that the value of infrastructure lies in the services it provides, green infrastructure has been distinguished from traditional gray infrastructure by focusing on the use of natural systems, such as wetlands and urban forests, to protect or enhance environmental quality by filtering air pollution, mitigating stormwater runoff, and reducing flooding. It stands to reason that such natural systems are most likely to provide such “ecosystem services” well when we respect and preserve their natural integrity. It also stands to reason that, to the degree that such systems face threats from urban sprawl and urbanization, their ability to perform those services for human populations is diminished. To say that development has often helped to kill the goose that laid the environmental golden egg is to state the obvious, no matter how many people want to avoid that truth. That does not mean that our cities cannot or should not grow and develop. It does mean that, using the best available natural science, we need to get much smarter about how it happens if we want to live in healthy communities.

Fiscalini Ranch Preserve in Cambria, California.

I mention this because, as part of the American Planning Association staff pursuing such issues, I spent three days in Washington, D.C., last week at a symposium we hosted with U.S. Forest Service sponsorship on “Regional Green Infrastructure at the Landscape Scale.” We were joined by about two dozen seasoned experts not only from the Forest Service and APA, but from the U.S. Environmental Protection Agency, several national nonprofits, and others to sort through the issues impeding better planning for green infrastructure. We explored major hazard-related issues such as wildfires, flooding, and coastal storms and how green infrastructure can or should function in relation to them.

This matters because there are huge costs associated with the way we choose to develop. There can also be huge benefits. Whether the ultimate ledger in any particular region is positive or negative is largely dependent on the approach we choose, and that is heavily dependent on how broadly or narrowly we view our responsibilities. Historically, in America, we have been rather myopic about the damage we have done to our environment, but our perspective has become more comprehensive over time, starting with the conservation movement in the late 1800s. But today, as always, there are undercurrents of more myopic attitudes and impatience with the more deliberate and thoughtful calculations a more long-term view requires. There is also the simple fact that understanding issues like climate change requires some degree of scientific literacy, something that is missing too often even in some presidential candidates.

But it helps to drill down to specific situations to get a firm sense of consequences. For instance, the Forest Service budget is literally (and figuratively) being burned away by the steadily and rapidly increasing costs of fighting wildfires. That is in large part because the average annual number of acres burned has essentially tripled since 1990, from under 2 million then to about 6 million now. As recently as 1995, 16 percent of the agency’s budget went to suppressing wildfires. Every dollar spent on wildfires is a dollar removed from more long-term programs like conservation and forest management. By 2015, this figure has risen to 52 percent, and is projected to consume two-thirds of the agency’s budget by 2025. Clearly, something has to give in this situation, and in the present political situation, it is unlikely to be an expansion of the Forest Service budget. At some point, a reckoning with the causes of this problem will have to occur.

What are those causes? Quite simply, one is a huge expansion in the number of homes built in what is known as the wildland-urban interface (WUI), defined as those areas where development is either mixed into, interfaces with, or surrounds forest areas that are vulnerable to wildfire. The problem with this is that every new home in the WUI complicates the firefighters’ task, putting growing numbers of these brave professionals at risk. Every year, a number of them lose their lives trying to protect people and property. In an area without such development, wildfires can do what they have done for millennia prior to human settlement—burn themselves out. Instead, a century of aggressive fire suppression has allowed western forests, in particular, to become denser and thus prone to more intense fires than used to occur. The homes themselves actually represent far greater densities of combustible material than the forest itself; thus fires burning homes are exacerbated by increased fuel loads. In addition, prescribed fire, a technique used to reduce underbrush in order to reduce fire intensity, becomes more difficult in proximity to extensive residential development. A prescribed fire that spun out of control was the cause of the infamous Los Alamos, New Mexico, wildfire in 2000. The entire situation becomes highly problematic without strong political leadership toward solutions.

At the same time, denial of climate change or even reluctance to broach the subject does not help, either. It compounds the difficulty of conducting an informed dialogue at a time when increased heat and drought are likely to fuel even more wildfires of greater intensity. The recent major wildfire around Fort McMurray, Alberta, displacing thousands of people, may be a harbinger of things to come.

That is just one sample of the issues we need to confront through a larger lens on the value of large-scale green infrastructure and regional cooperation to achieve positive environmental results that also affect issues like water quality and downstream flooding. Because we could produce an entire book on this issue—and the suggestion has in fact been made that we do so—I will not even attempt here to lay out the entire thesis. Rather, it may be useful to point readers to some resources that I have found useful in recent weeks in the context of writing for another project on green infrastructure strategies. Most of these are relatively brief reports rather than full-length books, enough to give most readers access to the basics, as well as references to longer works for those so inclined.

On the subject of water and development in private forests, a Forests on the Edge report, Private Forests, Housing Growth, and Water Supply is a good starting point for discussion. Because planning to achieve effective conservation at a landscape scale requires collaboration among numerous partners, an older (2006) Forest Service report, Cooperating Across Boundaries: Partnerships to Conserve Open Space in Rural America, may also be useful. With regard to wildfires, a recent presentation at a White House event by Ray Rasker, executive director of Headwaters Economics, a firm that has specialized in this area, may also be useful for its laser focus on trends and solutions with regard to development in the wildland-urban interface and the need for effective, knowledgeable local planning in areas affected by the problem. But I would be remiss if I did not bring readers’ attention back to a 2005 APA product of which I was co-author with Stuart Meck: Planning for Wildfires. It could probably use some updating by now, but every one of our central points, I believe, remains valid.

Happy reading to all!

Greening Greater Racine

How often do any of us look around our communities closely enough to fully understand the extent of the greening activity that is taking place? My guess would be that the vast majority of us—and I include myself—have no idea of the sheer volume of hours and effort that is expended, particularly on a volunteer basis, to keep our cities green and healthy.

I had the opportunity this weekend to get a glimpse of all that effort in a city of about 80,000 just an hour and a half north of Chicago, in Racine, Wisconsin, a lakefront community about 20 miles south of Milwaukee. The gift to me was an invitation from David Rhoads to be the featured guest speaker for an event on Friday evening, March 18, which set the stage for an Eco-Fest the following day at Gateway Technical College. The evening event took place at the SC Johnson Golden Rondelle Theater, a building with a flying saucer appearance on the grounds of the SC Johnson Co. in downtown Racine. I should note that this company has for years sponsored environmental programs in and around Racine and provided backing through its Johnson Foundation for the famous Wingspread conference center, often used for important policy discussions related to environmental and resilience issues.

My theme was “Green and Healthy: The Future of Cities,” but I did not speak about Racine because, frankly, I did not know nearly enough about it, but also because my mission was to introduce the audience to the wider range of urban forestry and green energy activities around the nation. In the bargain, I discussed the role of hazard mitigation and disaster recovery planning in creating resilient communities that minimize the waste of destruction from natural hazards, concluding with the examples of Joplin, Missouri, which included major reforestation efforts in its recovery from a major 2011 tornado, and Greensburg, Kansas, which engineered a green recovery that has made the town 100 percent reliant on renewable energy. In short, my mission was to paint a holistic impression of what it takes to create green and healthy communities.

But David does know very well what has been happening in Racine, which was one reason he was introducing me that evening. We have known each other for nearly 25 years since he was a professor of New Testament at the Lutheran School of Theology in Chicago, and I was chairing the Environmental Concerns Working Group for the Metro Chicago Synod of the Evangelical Lutheran Church in America. David has always been intensely interested in the theology of creation and environmental stewardship. The Working Group mission became, and remains, financing and enabling energy efficiency and renewable energy retrofits for Lutheran churches in the synod, which covers four counties and roughly 200 congregations. David and his wife, Sandy, also a pastor, have made Racine their home and are actively engaged in environmental activism on the local scene, including faith-based environmental awareness efforts. I was thus more than pleased to honor David’s invitation.

Because the intent of my own presentation was to “set the table,” in David’s words, for discussing the greening of Racine, I was followed by a panel of four local professionals: Julie Kinzleman of the Racine City Health Department, who spoke on healthy beaches and water supply; Nan Calvert, on environmental education centers in the area; Matt Koepnick, on urban forestry; and the Rev. Bill Thompkins, an African-American church leader, on neighborhood beautification. Without detracting from the other three in any way, I must say I was particularly taken by Thompkins’s approach. After stating that his inner-city church had asked the question “you don’t necessarily want to ask,” namely, what would happen if your church were no longer present in the neighborhood, he and his parishioners and neighbors undertook to reclaim a city park that had become a gang battleground and began to distribute and plant thousands of plants and trees. What difference does that make? As Thompkins explained, people are more likely to treasure an attractive neighborhood than a neglected one, and to begin to take responsibility for their local environment. Greening the neighborhood, in effect, was a way of restoring the social health of the people in the neighborhood. That echoed a theme I had introduced earlier, citing our APA work in Planning the Urban Forest, that trees have actual mental health benefits that have been documented in social scientific studies. A city that is green is also a city that is healthy for its people.

But what also struck me was the diversity of the efforts underway, including not one but several environmental education centers in the area, and an ongoing expansion of tree-planting efforts in Racine. David asked me for a one-minute closing observation on the program, and that was the one point I chose to make. Look around. See how much is going on around you that you did not know was happening.

The entire program set the stage for a much better attended event the following morning at Gateway Technical College, a school on the lakefront that provides training in environmental technologies. Eco-Fest Racine featured more than 50 displays by groups large and small, activist and educational, including children’s activities, which attracted the immediate interest of my wife, a retired elementary school teacher. Display topics ranged from garbage disposal to recycling to energy audits to urban gardening and forestry to environmental education and advocacy. It included secular groups and Racine Green Congregations, where a woman named Margie informed me ruefully that Wisconsin, under Gov. Scott Walker, an ideological conservative, has been losing its best scientists from agencies like the Department of Natural Resources because of anti-scientific bias from the administration. In the space of just a few hours, neither my wife nor I could absorb all that was offered in this cornucopia of information, but I came to realize one thing: Such events serve a critical purpose in exposing all of us to the breadth of activity that is present in our communities. I do not think Racine is unique, though it is blessed. I think other communities might contemplate the model of this program, the first of its kind in Racine, according to David, as a way of connecting people.  We need to be more aware of the ways in which we support each other so that those at work improving their communities can feel less alone. Networking, after all, is an important form of empowerment.

Restoring the Chicago Area Landscape

Chicago is not terribly old, as world-class cities go. It was incorporated only in 1837. The area was essentially devoid of European settlers until the 19th century. In the preceding centuries, the resident Indians, including the Potawatomi, had created a landscape dominated by oak ecosystems as a result of actively managing the landscape through the use of prairie fires. On the open lands of the Upper Midwest, there were few meaningful fire breaks, and the fires drifted east over vast grasslands. This North American fire regime changed the land by preventing the establishment of woody species, allowing oaks to dominate because of their thick, fire-resistant barks. The oaks in turn allowed more sunlight through their canopy and provided a thriving ecosystem for numerous species, including more than 800 species of birds and moths that eat their leaves.

The settlers who arrived in the 19th century, however, whether wittingly or otherwise, made quick work of the landscape they inherited from the natives they largely pushed out. They suppressed the wildfires in favor of plowing the prairie soils and savannas to create farm fields. Natural wildfires are few in northern Illinois; the wildfires that preceded European settlement were almost entirely a native artifact, which served the purpose of clearing hunting grounds but also served natural purposes of preparing the land for the sprouting of prairie plants. As the oaks receded, other trees moved into the void where fields did not prevent them, and in time maples and basswood took over, followed later by the invasive buckthorn, an introduced species. Today only 17 percent as much oak coverage survives as was present in the 1830s, and the landscape is highly fragmented. By the 1930s, only one oak-dominated parcel of more than 1,000 acres remained; today none remain. The numbers of various smaller chunks of oak land have also shrunk, just as steadily.

Chicago Wilderness, an alliance of organizations dedicated to open space, and the Morton Arboretum believe the metropolitan area needs to reverse the trend soon. Last August, I wrote about the Chicago Region Trees Initiative (CRTI) being led by the Morton Arboretum. On April 7, I attended a pair of meetings at the arboretum’s Thornhill Education Center that aimed at advancing the initiative. CRTI, which benefited for a period of time starting in the 1990s from federal support for some of its environmental projects, is now seeking new sources of funds as federal grants have waned, and is sharpening its focus into six areas of interest in order to clarify its mission for potential funders. Restoring oak ecosystems is one of those six focus areas. Another is landowners; most of the land that could be used to restore the fragmented oak ecosystems is private, and its owners must not only be willing to cooperate with the larger effort, but understand the reasons for it and its potential ecological, economic, and social benefits.

Economic and social? Yes. That is part of the appeal, one we laid out several years ago at the American Planning Association with the publication of Planning the Urban Forest: Ecology, Economy and Community Development, which began with an exposition of the documented benefits of the urban forest across dimensions of human health, pollution reduction, stormwater management, energy conservation, economic development, and other factors. Michael Leff, a research urban forester at the Davey Institute, has been developing a guidance document that stresses how good urban forestry needs to take a three-part approach that is as aware of the social and economic aspects as it is of the environment. Humans are essential to the success of any ecological plan, particularly in an urban setting. Public areas of nature or forest preserves contribute only a partial solution to a much larger problem, and solving that problem contributes significantly to human quality of life. It takes considerable scientific and social awareness to make the urban forest work in a highly developed setting where ecosystem fragmentation has become the norm.

Hence the social mission of CRTI: the need to share the story of the oak ecosystem with a wide variety of audiences throughout the area in an engaging manner that motivates them to take part in the initiative and participate in coordinated stewardship efforts. In addition, CRTI is reaching out to municipal public officials and staff, including planners, to provide training around the issues of municipal tree management and a model tree ordinance that CRTI is still developing for use by communities to advance the goals of urban forestry, including the oak ecosystem restoration efforts. There is also a role for the nurseries that grow trees and a need to keep them aware and involved so that they can be supportive of the overall effort, as well as for landscaping professionals, arborists, and others. I will return to this subject as the initiative progresses and evolves.

Meanwhile, I learned at the meetings of one valuable resource of which I was previously unaware: Bringing Nature Home, by Douglas W. Tallamy, published by Timber Press. So I looked it up, and it draws rave reviews for explaining the value of native plants and ecosystems, just as people at the meeting had said. It’s probably worth a download.

Trees for Metropolitan Chicago

Would you imagine that the trees in the metropolitan Chicago region provide compensatory value of $51.2 billion? This is the calculation produced through i-Tree, a free software program provided by the U.S. Forest Service to estimate tree canopy and the ecological services it produces for our communities. This is not a seat-of-the-pants calculation. There is a great deal of science behind it, as I have learned over the last two decades in interactions with the Forest Service and the larger professional community devoted to advancing the subject of urban forestry. There is a substantial technical literature these days about the benefits of the urban forest in terms of air pollution filtration, reduction of stormwater runoff, reducing soil erosion, reducing urban violence by providing a calmer, more pleasant environment, and enhancing real estate values. In short, trees have serious economic value. At the American Planning Association, we cited much of this research five years ago when we released Planning the Urban Forest: Ecology, Economy, and Community Development, a Planning Advisory Service Report we produced using a matching grant from the Forest Service.

The value of that document for urban planners has made it popular, and we have participated for several years at a national level in the Sustainable Urban Forests Coalition. But the important work on the urban forest occurs at the local and regional level. Think globally, but plant your trees locally.

It was a great honor, therefore, to be invited as one of about 100 participants to the kickoff meeting July 30 of the Chicago Regional Trees Initiative at the Morton Arboretum in Lisle, Illinois. The arboretum itself is the result of an environmental vision long ago by Joy Morton, the founder of the Morton Salt Company, who had a love affair with conservation—and put out serious money to launch the arboretum to prove it almost a century ago. I learned a good deal about this interesting man when reading a biography of him, A Man of Salt and Trees: The Life of Joy Morton, as a biography judge for the Society of Midland Authors’ annual book awards. The book was one of our 2010 finalists in that category.

Morton Arboretum is now leading this initiative with the help of numerous organizational partners and donors, nearly all of whom were present for the meeting, which lasted from 9 a.m. until 1 p.m., including a working lunch.

I will not go into the Regional Trees Initiative in great depth right now, but I intend to follow it more deeply in the future on this blog. Not everything is ready yet; an intended website is not yet up, the logo is still in development, and working groups are being formed. Lydia Scott, the director of the Regional Trees Initiative, appears to have a hard-working staff behind her along with solid institutional support. One of our group activities that morning was to sit at our respective tables and hatch ideas about what was most needed to make the initiative a success. Those ideas were added to a folding wall image of trees as branches, and then leaves were added with individuals’ names after we were asked what we and our organizations were willing to do to help. The people attending represented a variety of local governments in the area, regional organizations like the Chicago Metropolitan Agency for Planning and the Metropolitan Mayors Caucus, and educational and civic organizations.

What we learned over the course of the morning was the quality and distribution of information concerning the regional urban forest, which is decidedly uneven, leaving room for improvement through such an initiative. The city of Chicago, it turned out, had by far the best information concerning its urban forest, whereas in many other communities a more thorough tree census is still needed. But there are substantial resources to draw upon, such as “Urban Trees and Forests of the Chicago Region,” a Forest Service research report freely available online. The larger issues often relate to the uneven commitments, and distribution of resources, among the 248 municipalities in the region. A few have excellent plans for local forestry management, but many have none. There is room for both the U.S. Forest Service and the Illinois Department of Natural Resources to improve outreach with technical assistance, but there is also a burning need for an effective outreach campaign to educate both public officials and citizens on both the importance of the issue and the best means of moving forward. For purposes like that, the Communication Work Group is one of several the initiative has established to mobilize the resources of its many partners in the effort. That is why we were all there.

While I was busy in the meeting, my wife and two grandchildren were busy enjoying the arboretum. which includes some nice children's facilities and a cafeteria.

I plan to return to this subject in the future as the initiative progresses, particularly as RTI rolls out its website and other communication tools. Regular followers of this blog know that I attach considerable importance to this subject as a key element in the quality of urban life. If you live in another metropolitan area, what’s underway there to pursue similar goals?

Trees in the Disaster Recovery Equation

For the last two or three years, if not longer, I have been engaged in an ongoing discussion with people from the U.S. Forest Service and the International Society of Arboriculture (ISA) about the role of trees in post-disaster recovery. Phillip Rodbell, an urban and community forestry program manager with the Forest Service’s Northeast office in Philadelphia, has been particularly diligent in pursuing the question of how we can better protect trees in urban areas from storms and other major disasters as well as how to reduce the loss of trees in the process of removing debris after disasters. Too often, in the absence of qualified arborists or other forestry professionals, the existing incentives for debris removal cause more, rather than fewer, trees to be cut down and hauled away than is truly necessary. The question is how to change that.

The fact that some trees, sometimes many trees, do in fact get blown down in storms, crushing cars and occasionally people, snapping utility lines, and blocking roads, fosters the false perception in some minds that trees are inevitably hazards in themselves. In fact, inadequate maintenance of the urban forest, including inadequate attention to those trees that really do pose hazards, creates problems that can be prevented with better municipal tree pruning cycles and pre-planning for more appropriate vegetative debris removal after big storms. However, local resources, including professional expertise, can be overwhelmed in a more catastrophic disaster such as a severe tornado or hurricane. The sheer number of trees blown down by Hurricane Katrina, for instance, was staggering, well into the millions.

Phil and I ultimately decided that, if the Forest Service could provide a modicum of money to help sponsor what we decided to call a scoping session, and if ISA and the American Planning Association (APA) could contribute more modestly to support the project, we could perhaps bring together a team of subject matter experts, representatives of relevant local, state, and federal agencies, and people from interested nonprofit associations, and we could foster a meaningful discussion of how to address this problem. In the process, we might help save federal, state, and local governments millions of dollars annually in avoidable debris removal costs.

This spring, we succeeded in bringing that package together and initiating a contract between the Forest Service and APA. The result was a two-day discussion held June 16-17 in APA’s Washington, D.C., offices, involving more than two dozen people, mostly in-person, but with a handful joining by conference call from remote locations in New York and Mississippi. A summary of that discussion, and the issues it addressed, is now available on the APA website, along with a bibliography of resources on the topic, and a series of briefing papers prepared by the invited experts. I invite my readers to check it out. To learn more, click here.
