The Appropriateness of Nature in Cities

By Dom Nozzi

July 18, 2004

Introducing nature into cities nearly always degrades the human habitat.


I say this about nature in cities even though I am an advocate for urban open space.

After all, I have a degree in environmental science, so I understand the importance academically.

When I was a child, the most profound, critically important, priceless experience I had was to be able to play in the neighborhood woodlands. I did that ALL the time. The main inspiration for my becoming a city planner was that I wanted to be in a job in which I could work to see that future generations of kids had that same opportunity, as NOT having that experience would lead to an awful, sterile, barren childhood. Indeed, a study once looked at a HUGE number of variables to determine if there was a correlation between childhood experiences and wanting to conserve the environment as an adult. The study found that there was one variable that stood out head and shoulders above the others. Adult conservationists typically were able to engage in unstructured, unsupervised play in natural areas near their home when they were kids.

Because of the above, I remain a leading advocate for establishing an urban greenway trail systems in cities. Such a system is the only effective way I know of to allow kids (and

adults) to have easy walking/bicycling access to the natural world, on a regular basis, right outside their back door. Nothing is better able to create the army of conservationists our environment needs.

I would therefore hold my strong desire for urban open space up against anyone else with the expectation that my desire would be stronger. I am intensely supportive of URBAN open space.

Note that I say urban open space. This is a crucial qualifier. The urban habitat (in contrast to the suburban and rural) MUST be compact and walkable if it is to be a high quality urban habitat. That means that if we are to introduce nature into the urban world, we must be as careful as if we were planning to introduce human activity into a wildlife habitat.

In the former case, the introduced nature MUST be compact and walkable. In other words, small, vacant woodlots, plazas, squares, piazzas, utility corridors, creek corridors, etc. are perfectly compatible with walkability. One can easily walk from origin A to destination B without an enormous amount of physical exertion. By contrast, putting a golf course or even a 50-acre park in the middle of a city creates an UNwalkable condition, as the distance between A and B becomes too excessive to easily walk (Central Park in NYC can work because NYC has extremely high densities and a quality transit system that means you can easily walk or ride to all of your daily needs along the PERIMETER of the park without having to cross it on foot).

In other words, big open spaces in a lower density community would create unwalkable spaces that would degrade the urban habitat in such cities.

The key for most cities is to preserve and create URBAN open spaces while retaining walkability. Greenway trails that wind their way through neighborhoods and small parks are compatible.

Big, unwalkable parks are not.

Fighting the Correct Battle

by Dom Nozzi

[Updated Jan 2009]


I’ve been a lifelong environmental conservationist. I lead a very low-impact lifestyle: vegetarian, bicycle commuter, solar water heater, restoring a 10-acre cattle pasture to a native hardwood forest, purchase more used than new products, etc.


Much of this ethic comes from my father, who was a strong environmentalist. My upbringing, which included lots of play-time in wooded areas, inspired me to obtain a bachelor’s degree in environmental science and a master’s degree in environmental planning.


Over the years, I’ve been a member of Earth First!, Alliance for a Paving Moratorium, Friends of Alachua County, Alachua Greenway Alliance, and the local chapter of the Sierra Club.


Much of my professional work over the past 15 years has involved the preparation or strengthening of city environmental plans and environmental development regulations.


For example, I wrote the long-range environmental conservation plan and solid waste plan for Gainesville, Florida, prepared a strict, esteemed noise ordinance for that city, included xeriscape requirements and prohibitions of non-native invasives to the city landscape ordinance, prepared a computerized land ranking system for public acquisition of important natural areas, prepared ordinances that further protect the city wellfield,  upland ecological communities, and nature parks. I also worked for 18 months as the development rate control planner in Boulder, Colorado.


Because of all this, it should surprise no one that I appreciate and respect the important work that others do to ensure that our society achieves sustainable environmental conservation.


My professional work in recent years has become much broader. I am involved in a number of “big picture” projects that give me a larger view of the social and environmental problems we face. Much of this work has been to prepare the long-range transportation and land use plans for Gainesville, which has sharpened my understanding of the underlying factors threatening our ecosystems and quality of life.


Due to this work, I am growing increasingly concerned because many of the admired environmental allies I worked with in the past seem to be focused on the wrong battles.


An enormous number of necessary, hard-fought struggles were fought by environmentalists in the 1960s, 1970s, and 1980s. It is crucial, yet counterintuitive, perhaps, to realize that we succeeded in winning most of those battles! At the national, state, and local level of environmental protection.


smokestackHard as it may seem to believe, we now have quite strict, protective regulations in place for the direct, obvious, easy-to-recognize sources of environmental degradation. We are now much, much tougher with regulations that ensure that smokestacks, sewer pipes, toxic waste dumps, and environmentally hazardous products do not harm our environment. We’ve fought the battle against these direct, “point” sources of pollution, and surprising as it may sound, we have largely won.


To effectively address our substantial, remaining environmental battles, we must now turn our attention to the much more difficult and seemingly intractable environmental threats; namely, the widespread “non-point” sources of pollution, such as stormwater runoff from roads and parking lots, emissions from car tailpipes, and new residential and non-residential developments sprawling into our outlying (and more sensitive and important) areas.


Yet despite all the victories we have won regarding direct sources of pollution,  intelligent, conscientious environmentalists are engaged in a desperate, sometimes hysterical attack against their elected officials, claiming that local plans and regulations are offering a “blank check” to developers, who will be allowed to “have their way” in developing projects that will destroy our urban natural areas and neighborhoods.


How can such an attack be possible? Shouldn’t the defenders of natural areas and neighborhoods be cheering on the impressive gains made with our elected officials, our plans, and our development regulations?


In my opinion, what is happening is that successfully correcting the direct forms of environmental pollution (the smokestacks and sewer pipes), and instituting neighborhood-protecting tactics, did not deliver us a pristine, sustainable ecosystem, or quiet, stable neighborhoods. In fact, a tidal wave of evidence—global warming, species extinction, air pollution, water and groundwater pollution, loss of ecosystems, loss of quiet neighborhood character—is bombarding us with the message that we are, more than ever, losing the battle to save our environment and our neighborhoods.


The obvious answer for many? Attack environmentally-oriented and neighborhood-protective elected officials for being pawns of developers! Disparage environmentally-strict plans for being too weak! Scream for stronger development regulations to require even more protection against smokestacks, sewer pipes, and toxic waste! Demand that the City take away a person’s constitutional right to have reasonable use of their land.


Isn’t it perfectly clear that these are the solutions?


The frightening problem is this: it is hard to realize that we’ve already won those battles. After all, isn’t it true that there is ongoing degradation of our environment and our neighborhoods?


It is therefore too easy for well-meaning crusaders to unintentionally waste precious time, energy, and money battling the wrong problem.


It is difficult to see that the essential problems are now indirect, less obvious, and less focused on “evil corporate business polluters.” Instead, they are more widespread, systemic, and incremental. Now, the sources of degradation are not, individually, big and nasty pollution sources. Instead, they are indirect and embedded into our auto-based, suburban sprawl lifestyles. Added up, though, these indirect impacts lead to substantial destruction of outlying, regional ecosystems and residential neighborhoods.


Now, instead of smokestacks, the big threat is indirect and more invisible: Things like widening urban roads, which open up markets for remote, sprawling subdivisions. These remote subdivisions trample our large ecosystems, further lock us into the downward spiral of auto dependency, and promote the continued decline of older, in-town neighborhoods.sprawlovertakesfarm


We have met the enemy and he is us.


Our auto-dependent, suburban lifestyles demand that we angrily insist our politicians give us low densities, big, high-speed roads; large, free parking lots and cheap gas. It is impossible for us to realize that such demands are a recipe that, ironically, locks us into the very thing that we fight against: degraded ecosystems and degraded neighborhoods. The handy solution is to find (the usual) scapegoats to blame.


Perhaps this is what we should expect. After all, the indirect, widespread, lifestyle-based problems don’t seem like problems we can do much about. It seems so much more feasible (and a way to ease our own guilt) to blame a few diabolical developers or corporations.


The convenient solution for this search is an artifact of the past: Evil developers, corrupt politicians, unsympathetic professional staff, and polluting smokestacks. It can’t be that we are to blame! It must be the “bad” guys!


Is it any wonder that there is no longer any trust, credibility, or respect given by citizens to developers, staff, or elected officials, even when they are intelligent, sympathetic, and well-meaning?


To their credit, the national Sierra Club has recently started to focus on the overriding, “big picture” problem that is overwhelmingly responsible for threatening our ecosystems and neighborhoods: Auto-dependent urban sprawl.


We must find effective ways to control auto-dependent sprawl if we expect to save our natural areas and neighborhoods. We must find ways to see that future development delivers us walkable, compact, neighborhood- and human-scaled projects rich in civic pride and transportation choice. We must set about the task of building cities and towns that are designed to make people, instead of cars, happy—so that we will mostly be clamoring to live in the city, and can reduce the widespread desire to flee the unpleasant cities for the perception of suburban bliss.


This is the only way we can restore trust, confidence, and respect.


And an essential way to do that is to not misdirect our time and energy by blaming the usual suspects…
