Parks and Urban Seniors

Source: EPA

The New York Times ran a story on how the city is attracting retirees and making the city more amenable to seniors. Among other items such as light timing at intersections to allow more walking time and places to get a drink of water, the article refers a few times to how parks are a key attraction for older citizens. From the article:

New York has become a safer city, and we have such richness of parks and culture that we’re becoming a senior retirement destination,” said Linda I. Gibbs, New York’s deputy mayor for health and human services. “They come not only with their minds and their bodies; they come with their pocketbooks.

This seems like a good time to again bring up the EPA’s recent report on planning communities for older Americans. The book specifically mentions the need for nearby public parks and quality gathering places. These are the senior and recreation centers, the walkways and trails, the outdoor performances and natural areas for people to get out and enjoy during the day and evening hours. And in the end, making a community friendly for seniors really is the same as making it friendly for all people.

The Range of Street Closure Efforts in Cities

Cities around the world are shutting down streets for pedestrian, cyclist and mass transit thoroughfares and plazas, wrote John Mattson in an article in Scientific American last month. Case in point is New York City’s move to shut down portions of Broadway around Times and Herald Squares. These car-free areas in the heart of Manhattan have become incredibly popular with pedestrians — locals and tourists alike. But the actions described in the article can come in many ways, so exactly how are cities successfully shutting down these car free spaces and creating pedestrian zones? Below we take a shot at describing some different forms.

1. Permanently closing street areas. Copenhagen is a poster child for this, and several cities have followed suit around the world, in places such as Arequipa, Peru and as mentioned, in Times Square in New York City. Copenhagen architect/planner Jan Gehl described the Copenhagen actions as a series of small steps over many years in gaining public support and success.

A word of caution here also. Many U.S. cities created so-called “pedestrian malls” on wide American streets starting in 1959 in Kalamazoo, Mich. and as many as 200 more in the following 20 years. Yet only a select few have been successful. The successful and surviving ones (the Kalamazoo mall was converted back to cars) seem to have been programmed and well-managed (mostly in college towns) in a more updated view of how public space functions. Two others, the 16th Street Mall in Denver and Nicollet Mall in Minneapolis are viewed as successes, but they are actually transit malls — and well managed and programmed.

2. Putting a road diet on streets and creating pedestrian space from freed up areas. Sometimes, a street may be best left open to traffic on some level instead of turned into an all pedestrian area. This could be because the street is too wide, it has insufficient density to have sole pedestrian access or it may be decided that the street is an important thoroughfare for car traffic.  Two examples come to mind. First, again in New York, aside Madison Square Park the city narrowed streets to provide a pedestrian plaza with chairs and tables with a stunning and direct view of the famous Flatiron Building. In Seattle, the parks department is building a linear park on a street known as the Bell Street Park while still maintaining limited car flow. This is basically a variation of the Dutch Woonerf or British “Home Zone.”

3. Closing park roads. Countless examples from across the country from Central Park in New York to Golden Gate Park in San Francisco and Kansas City’s Cliff Driver in between. This is a growing trend, and there remain many roads that are not serving their parks and cities well by being open to cars.

4. Temporary “ciclovia” closures. Around the world, city streets are being shut down to cars on one or more summer weekend days — in the U.S. this includes Portland’s Sunday Parkways, New York’s Sunday Streets and Baltimore’s B-more Streets for People. The concept originated in Bogota and then other Latin America cities such as Mexico City and Guadalajara before going global.

There are more ways this has been done, including one idea in the Scientific American article from Paul Steely White of New York’s Transportation Alternatives on “time-flexible streets,” which might be open to vehicle traffic during part of the day and pedestrian-only at other times. “You’re accommodating peak use—that could be peak deliveries in the morning and peak pedestrian use during lunchtime,” he says. “That’s something I think you’ll see more of, and something we’re pushing for.” Some streets already have this, but not on a regular basis — so we will watch for some examples.

There are more examples or one could use a different typology for closing streets, but in any case, these efforts can help land-starved cities provide great public space to residents by just using land already in public ownership.

City Park Fountains and the Need for Maintenance

The New York Times had a nice piece the other day on the city’s 50 plus fountains. If there is any quintessential park design feature, it may be the fountain. They were included in earlier plazas (think Rome), the larger parks of the 1800s such as Central Park and all of its cousins acro0ss the country, and they appear in variations today in features such as the “spraypad,” a hybrid of a fountain and a playground.

For city parks to be successful, they need great water features. Yet it takes money to maintain them, and neglecting such facilities can make a real negative impression on visitors and residents. (For instance, the water fountain in Washington, D.C.’s Columbus Circle, just in front of Union Station underwhelms despite its placement in front of one of the nation’s busiest transport hubs.) Instead of investing in large sports complexes and convention centers, smaller and more sustained investment in the public realm of a city can go a long way in creating an environment pleasurable to residents and visitors alike.

And as the Times article points out, things like fountains do not pay for themselves, quoting a parks department official who noted that that his crews retrieved little money — “The homeless people go in there at night and do the job for us.”

Innovations in Urban Green, Questions for Peter Harnik

We asked Peter Harnik to answer some questions about his new book, Urban Green: Innovative Parks for Resurgent Cities, that covers how cities can plan for parks as well as how to create them in “all built-out” settings.

Your book addresses many age-old questions about parks and cities. Let’s start with the big one — how much parkland should a city have?

“Should” is the wrong verb. “Should” implies that the outcome is decided by planners. The right verb is “want”: “How much parkland do we as residents and taxpayers want?” It’s a political issue, and it’s got to be approached politically by building a base of active park supporters. Every city has a different geography, a different history and a different culture — it’s not one size fits all. I think people sometimes use the word “should” in the hopes that someone else will do the work for them. No great park system was created solely by planners using official standards.

But still — don’t even advocates need to know how their city compares to others?

Oh, definitely! That’s why I give some comparative numbers in the book and many more on our web page (at www.tpl.org/cityparkfacts). If you take a trip to Boston or Minneapolis and like what you see, you can compare what your city has with them — everything from acreage to playgrounds to recreation centers to swimming pools. Which is why I always say it’s not just about gross acreage. One place may have lots of young people primarily interested in sports fields, another may be tilted toward older folks who want walking trails through bird-filled marshes. The environment also matters: some cities easily support lush forested parks, others are built on arid deserts where trees are essentially alien species. But the most important factor is population density. Crowded New York and San Francisco have so much concrete everywhere that every added pocket park is magical. Roomy Jacksonville and Oklahoma City, with thousands of large suburban-style yards are already halfway natural even not counting their parks. Density has a major impact on how people think about parks and how they use them.

The subtitle of the book is “innovative parks for resurgent cities.” What does it mean for parks to be innovative?

When cities are young, small and expanding, parks are added on the leading edge of the growth margin. They consist of natural lands that are donated or purchased — farms, forests, woodlands, wetlands, deserts. The process is known as conservation.

In older cities that are “all built out” there is nothing natural to conserve besides the already-existing parks. New parks there must be created through development rather than conservation. To make a park from a derelict parking lot, for instance, you wouldn’t conserve it — doing that would merely retain a derelict parking lot. You’d have to tear it up, regrade it, plant it, and fit it out with a playground or a sports field or a fountain or whatever the community wanted.

The goal in built-out cities is to use innovation — acquiring no-longer-needed parcels from other government agencies, sharing land with other users, utilizing previously wasted surfaces like rooftops and highway air rights, installing gardens in gap-toothed neighborhoods, pushing developers to donate land for parks, even just making better use of existing parkland. Every one of these approaches is happening in some city right now, and a few cities are doing almost all of them.

The book touches on the different kinds of parks, from social spaces to those nearly devoid of people but full of nature. How can cities deal with such a broad spectrum?

After Gertrude Stein said, “A rose is a rose is a rose,” you’ll notice she didn’t say “A park is a park is a park.” The large number of park types, ranging from insect-filled wetlands that have no human visitors to center-city brick plazas that have no grass and sometimes even no trees, can be confounding to any planning process and even to a general conversation. The vast number of activities that can and do take place in parks makes the discussion even more complex. I don’t use the confusing words “passive” and “active,” but I do like the new concept coming out of Portland, Ore., where planners talk of a spectrum that ranges from spaces of extreme sociability to spaces of extreme ecological purity. They created a three-way classification they call “people-to-people” places, “people-to-nature” places, and “nature-to-nature” places. The former two support different types of human recreation, the last is for pure conservation (or what some people are now calling “green infrastructure”). The Portland system is based on the relationship among experiences, settings, and activities, with experiences being paramount.

Are parks important in spread out cities and sprawling suburbs?

People with large yards don’t need parks as much for things like barbecue picnics, playing catch or kicking a ball, going to a playground, or sitting on benches, but they still need them for many other reasons: organized sports fields, greenway trails, large forest reserves. But there’s something else. As America seeks to reign in sprawl, we need nodes to build some density around. The most powerful nodes are probably transit stations, but I believe parks are just about as significant. If someone has a beautiful park a block or two away, he or she may be much more willing to live without a yard in a townhouse or an apartment in a walkable neighborhood with other nearby conveniences. It’s called park-oriented development and it could have a big impact on our cities and suburbs.

You suggest numerous ways cities can add parks — decking freeways, sharing schoolyards, using old landfills, greening rooftops, and much more. Is there a place to start? What do you say if a mayor asks you what’s the biggest bang for the buck?

Again, every city is different. Dallas has a below-grade freeway segment that is just crying out for a park deck to link uptown with downtown and serve as a seed for redevelopment. Boston happened to have a perfectly located 100-acre landfill that was all filled up and ready for conversion to sport fields. Space is so tight in Brooklyn that New York was forced to tackle the complexities of an agreement to use formerly locked schoolyards as after-school parks. The creative folks at Oakland Cemetery in Atlanta are committed to making that space as absolutely park-like and inviting as possible. The purpose of my book is to open people’s eyes to the many possibilities out there — all of them proven — but each will have to be analyzed on the local level as to feasibility.

If there is one piece of advice you could give to a city, what would it be?

I would say, “Lead with your parks.” The two blockbuster infill parks of the 21st Century — Millennium Park in Chicago and The High Line in New York — have each generated well over a billion dollars of redevelopment and renewal, not to mention tourist revenue and all-around “buzz.” It’s similar with innovative parks in St. Louis, Denver, Houston, Boston, Atlanta and other places. If park advocates and mayors create beautiful, exciting and fun spaces in the hearts of cities, developers, tourists and residents will quickly follow.

For those in New York, Peter will be presenting on the book at The Arsenal in Central Park on July 27th at 6 p.m. (cost is free).

Parks and Increased Immunity

Portland's Forest Park (Portland Development Commission)

Anahad O’Connor of the New York Times tests the claim that exposure to plants and parks can boost immunity. The finding: yes. According to the article:

For those who can take the heat and cope with the pollen, spending more time in nature might have some surprising health benefits. In a series of studies, scientists found that when people swap their concrete confines for a few hours in more natural surroundings — forests, parks and other places with plenty of trees — they experience increased immune function.

The studies cited can be found here, here and here. They don’t specify city parks, so that should be considered. But many cities, and many parks, are full of forests. (The most well-known urban parks, such as Central Park, Prospect Park (Brooklyn) have them, and places such as Forest Park in Portland and Rock Creek in DC are basically all forest.) The take-home here is that programs and facilities that allow people to get out into these places may help improve their health.

Streetcar Investments Including Recreational Destinations

The US Department of Transportation this week awarded nearly $300 in grants as part of the administration’s livability initiative to better coordinate transportation, housing and commercial development investments to serve the people living in those communities. The funds come from the Urban Circulator Grant Program and the Bus and Bus Livability Grant Program.

Streetcars were funded in Cincinnati, St. Louis, Charlotte and Fort Worth, and one noticeable piece of those cities’ plans is not only to connect downtown employment centers, but route streetcars through and by major recreational destinations such as parks. As FTA Administrator Peter Rogoff noted, “Streetcars are making a comeback because cities across America are recognizing that they can restore economic development downtown – giving citizens the choice to move between home, shopping and entertainment without ever looking for a parking space.”

Cincinnati, which received $25 million for its route, is planning a line that will hit the city’s riverfront park and stadia, the soon-to-be-renovated Washington Park in Over-the-Rhine, 20-acre Inwood Park north of downtown, and the Zoo and Botanical garden at the northern end. In St. Louis, which also received $25 million, a street car route will link up the city’s signature green space, Forest Park along with the University District.

Other already-built streetcars also have linked to key recreation destinations, such as Seattle’s Lake Union Trolley linking up with the park of the same name. Streetcars are being touted for their potential effect on economic development, and including these recreational destinations, along with employment and residential may be a key to their success. It is encouraging to see the federal government including a variety of factors in these investments — and living up to the goals of its livability initiative.

Accessibility to Destinations Biggest Driver of Driving

A new study shows that the best way to minimize driving may be through developing around destinations accessible to jobs, shopping and recreation — and coupling that location with walkable block sizes, a good street network and mixed uses. The report was a result of a “meta analysis” by Reid Ewing and Robert Cervero, that reviewed over 50 individual studies on the subject. Smart Planet interviewed Ewing about the study’s results. Ewing:

The best way to minimize driving appears to be to develop in existing centers near the core of the metropolitan area, in areas of high destination accessibility where there are a whole lot of jobs near by. That’s the most important single factor.

We found other factors like mixed-use and intersections and block size. They fall into a second group that is less important than destination accessibility, but are more important than density. Density turns out as less important than land-use mix where shops and schools and workplaces are near to people’s homes.

If you’re trying to minimize vehicle miles traveled and maximize walking and transit, you’re better off emphasizing mixed-use and destination accessibility than just bumping up density. A dense development in the suburbs, far from transit and employment centers and stores, is probably not going to buy you much in the way of walking and transit use. Almost any development in the central city is going to be more efficient from a transportation standpoint.

Ewing defines “destination accessibility” as within a short distance of “a lot of what are referred to as ‘trip attractions’ — shopping, employment, recreational facilities.”

In developing and infilling urban neighborhoods, the provision of nearby and accessible parks can be a key ingredient, along with shops, transit and the like in providing that reduced car reliance.

Retrofitting Suburbia: a Role for Parks

Ellen Dunham-Jones spoke in a TED presentation on retrofitting suburbia. If you’re interested in how metro areas can retrofit their suburbs into places that turn underused parking lots, mall sites and other moribund areas into walkable places with shops, housing, parks and accessible transit, this video is a worthwhile twenty minutes.

In particular, Dunham-Jones mentions some efforts to restore ecological features and provide new public parks as part of redevelopment. On a very related note, the Red Fields to Green Fields project might be a great way to take advantage of so many fallow suburban commercial properties by turning them into parks that entice walkable urban development around them. (Interestingly, this TED talk was in Atlanta, where much of the thinking and planning about Red Fields to Green Fields has occurred.)

For those interested in reading more about retrofitting, a Christian Science Monitor article last year offers a nice overview, and there’s also Dunham-Jones’ (and June Williamson’s) book called Retrofitting Suburbia.
