You might have noticed some
new choices for environmentally-friendly
cleaners on supermarket shelves. Most
people pass them over. They worry
natural cleaners won’t do the job as
well as the regular stuff. But, the
places that need to be the cleanest,
the most sterilized, are finding that
green cleaners are more effective.
Julie Grant reports that hospitals
have started replacing the old chemical
cleaners with natural products:

It used to stink whenever the cleaning guys at the Cleveland
Clinic needed to strip the floors. The patients, doctors and
nurses would complain about the chemical vapors. So, they
started clearing areas of the hospital on floor cleaning days.

(sound of cleaning machine)

Today Dennis Casey says they drive around on a new
scrubbing machine.

“That’s an automatic stripper, it’s called an orbital scrubber.
And it strips the floors without the use of chemicals – only
water.”

The new-fangled machine looks kind of like a riding mower.
They run over the hospital floors spraying cold water and the
machine scrubs. Casey says it works just as well as the old
chemicals – but it doesn’t smell and takes a lot less time.

That’s music to Christina Ayers’s ears. She’s environmental
coordinator at the Cleveland Clinic. Ayers says the most
important part of picking cleaners and tools – is to make sure
they’re going to work.

Of course, water alone isn’t enough for every job. Hospitals
need disinfectants. Ayers says the Environmental Protection
Agency helps with that.

“EPA actually certifies disinfectants, and all products that are
used as a disinfectant have to go through the same rigorous
testing to ensure their efficacy. But what we’re buying when
we’re buying the products is the efficacy of the product, not
all the additional chemicals and perfumes and other
elements that are not necessary for the product to function
well.”

Ayers says lots of people are used to that ‘hospital smell.’
But that’s often just a cocktail of cleaning chemicals – and
doesn’t create the healthiest environment for patients and
staff.

They still use bleach at the Clinic – it’s a great disinfectant –
but only in specific places – door handles and other high
traffic areas. Ayers says other places, like windows and
bathrooms, can get just as clean without other harsh
chemicals.

At first, it was tough for some folks on the cleaning staff to
accept the new, fragrance free products. Those strong
smells signaled a clean room. Ayers says some would use
the natural cleaners – but then spray chemical air fresheners
just to make sure the rooms smelled clean.

“That’s a bridge we have to cross. We have to help people
understand that clean smells of nothing. And that when
you’re smelling all of those smells that are associated with
clean, that chemical smell, the smell of bleach, those
perfumes, all those volatile organic compounds that come
out of the cleaning products – you don’t want to be inhaling
all of that product. You really want it to be working, you want
to purchase the efficacy of the product and not all of that
extra stuff that goes into our air.”

Ayers says people with asthma and other breathing
problems understand that right away. And, often, others just
need a little explanation.

“And once you explain that to people – that you’re using a
product that’s safer for the indoor air quality of our hospital –
It’s an easy step, people understand it. And they quickly
grow accustomed to the new smell of clean, which is a much
more mild and fresh and less chemical smell than what you
might be familiar with – even in your own home.”

In fact, I talked with one woman on the cleaning staff who
says, since the hospital switched to more natural products,
she’s seen how well they work and has started using green
cleaners at home.

Upgrading Tired Hospital Food

  • Two gourmet chefs managing the kitchen at St. Luke's Hospital in Duluth are adding organic vegetables to the menu. (Photo by Stephanie Hemphill)

Some hospitals are trying to heal the food that they serve. The GLRC’s
Stephanie Hemphill takes us to one hospital that making efforts to spice
up their menu:


(Sound of elevator)


St. Luke’s is the smaller of Duluth’s two hospitals. Their motto could be
“we try harder.” Several years ago, the hospital put two chefs in charge
of the housekeeping, laundry, and food.


In the kitchen, there’s the usual industrial stoves and dishwashers, and a
long assembly line where workers fill the trays for patients, based on
what they’ve ordered.


“The patient fills out the menu, I’ll have this entrée and that salad and this
beverage; then as the tray moves down the conveyor belt, they look at the
menu and put on the appropriate products.”


Mark Branovan was a gourmet chef at restaurants in California’s wine
country. In that part of the world, they take their fresh fruits and
vegetables very seriously.


“We did very little of our produce buying from the big distributors; we
had local guys that would grow lettuce for us, and herbs for us, and tomatoes…
anything we wanted. So that just kind of rolled over for us into, if
we can do it for a restaurant, why can’t we do it for a hospital?”


It’s harder to do in this part of the country, where you can grow lettuce
for about half the year and you’re lucky to get a tomato at all. But
Branovan and his colleague, LeeAnn Tomczyk, decided not to let that
stop them.


Tomczyk was a chef in a trendy restaurant in Wisconsin before she took
the job at the hospital. She says when she first came here, she was
appalled at some of the things on the menu.


“YOu know the patient was able to pick a jell-o salad and a piece of cake.
Well, to me jell-o is a dessert but to them it was their salad and that
was their vegetable, and that wasn’t right.”


Tomczyk and Branovan started to add more fruits and vegetables,
including organic items, to the menu, but they learned to pick their
battles.


“When I tried to change some of the casserole dishes, and some of the
traditional northern Minnesota fare, I was met with some serious
resistance from our customers and our patients who said, ‘Yeah, we have
tater tot hot dish on our menu because we like it.'”


One of the first items to change was the milk. Now the hospital serves
hormone-free milk to patients in the rooms and workers in the cafeteria.
Tomczyk says she’s convinced hormone-free milk and organic food are
healthier. She says an organization devoted to helping people heal, like a
hospital, needs to think about healing in broad terms, even globally. She
says buying local food avoids long-distance transportation, with its heavy
reliance on polluting fossil fuels.


“And the introduction of pesticides and herbicides, and that getting into
our water systems, it’s that whole cycle, and we’re using more and more
these days, and I think it’s just got out of hand.”


The hospital is also committed to reducing waste. It freezes unused
portions and gives them to soup kitchens and homeless shelters. It sends
its food waste to the city compost pile.


St. Luke’s is a member of a hospital buying group that negotiates prices
with big producers like Pillsbury. Each hospital is supposed to buy a
certain percentage of its food through the buying group. When Branovan
and Tomczyk asked the distributor for hormone-free milk, the distributor
didn’t carry it.


“We had to actually get a waiver that says they will allow us to buy off-
contract.”


Branovan got a similar waiver to buy organic fresh fruit, and greens for
the cafeteria salad bar. He hopes to add more organic and locally-grown
foods.


Branovan says St. Luke’s is the first hospital in the region to ask the
buying group to supply hormone-free milk and organic vegetables, but
hospitals and schools on the west coast and east coast are doing it on a larger
scale.


James Pond is editor of Food Service Director, a trade magazine.
He says the movement will grow.


“The pricing advantages will in some ways level out, where if it becomes
important enough to the clientele, the food service operators will respond
by providing products in this manner.”


Some hospitals organize a farmer’s market to serve their workers, as a
way to introduce them to organic and local foods. Then they add those
foods to the cafeteria and patient meals. At St. Luke’s, they feature
organic food at company parties.

Respiratory Rankings Wrong?

A recent ranking of the worst U.S. cities for respiratory infections is being called into question. The GLRC’s Erin Toner reports:

Transcript

A recent ranking of the worst U.S. cities for respiratory infections is
being called into question. The GLRC’s Erin Toner reports:


The list was compiled by BestPlaces.net, and funded by the
pharmaceutical company Sanofi-Aventis. It was based on the prevalence
of respiratory infections, prescriptions, and the rates of antibiotic
resistance. But one physician says the methodology might not give an accurate
picture.


Doctor Randolph Lipchik teaches at Medical College of Wisconsin. He
says the data is likely being skewed by the antibiotic resistance factor.


“Most respiratory tract infections, whether it’s sore throat, or an ear
infection or bronchitis, is viral, and antibiotics don’t treat that, and
antibiotics don’t prevent spread of those infections.”


Lipchik says it might be that hospitals in cities high on the list have a
high amount of resistant bacteria, making it look like they have more
trouble with infections than cities ranked better by Bestplaces.net.

Not Quite Ready for Bioterrorist Attack

  • Mock evidence of radiological material to make a dirty bomb gives trainees an idea of the kind of materials they might find in a terrorist operation. (Photo by Lester Graham)

Since 9/11, emergency responders have been practicing for new kinds of emergencies.

Recently, the Great Lakes Radio Consortium’s Lester Graham was allowed behind the scenes in a terrorism attack training exercise:

Transcript

Since 9/11, emergency responders have been practicing for new kinds of emergencies. In
addition to fires and hazardous materials spills, emergency personnel have been training
to deal with terrorist attacks. Recently, the Great Lakes Radio Consortium’s Lester
Graham was allowed behind the scenes in a terrorism attack training exercise:


(coughing)


These two men are the victims of some kind of biological toxin. They were investigating
an abandoned rental truck and now they’re writhing on the ground after a package
spewed some kind of liquid.


(chatter between mock victims) “You alright, man?” “What was that?” “I don’t know
what that was. It hurts.”


These guys are acting. They’re part of a huge training exercise put on by the
Environmental Protection Agency. Dozens of firefighters, emergency medical personnel,
EPA investigators, the FBI and people in t-shirts identifying themselves with acronyms
for agencies most of us have never heard of. They’re all working through a couple of
scenarios. So far today, they’ve discovered radioactive material to make dirty bombs and
some kind of lab set up to make a chemical like sarin nerve gas… and then there’s the
rental truck which is loaded with nasty chemicals.


Mark Durno is the U.S. EPA’s On-Scene Coordinator…


“We have some very distinct objectives with this exercise. One is to practice responding
to unusual situations that might involve weapons of mass destruction. In this particular
exercise, we’re practicing chemical agent and radiological agent response.”


There are lots of new things to learn. Coordination between agencies… and new
techniques. In this exercise, Detroit city departments are learning to work with federal
agencies. Melvin Green is with the Fire Department’s Emergency Medical Services. He
says this exercise is good. He’d rather see his medical technicians make mistakes here
than during a real emergency… where his worst fears might be realized.


“I would have to say that, you know, them become casualties, that’s probably my biggest
fear. This is why we want to educate them on—and this is why the exercise is so
important. We want to educate them on the possibilities. Keeping our people safe
reduces casualties.”


That’s because if the emergency medical personnel are hurt… fewer people will be
treated.


The idea of a terrorist attack with radiological or biological agents is the kind of
nightmarish scenario that no one really wants to think about… but it’s something
emergency responders HAVE to think about.


During this day-long exercise… these trainees are upbeat, they’re confident in their
response. They feel they’ve come a long way in the nearly three years since 9/11.


But other emergency service experts are not quite as upbeat. Just 40 miles from this
training exercise… at the University of Michigan Hospital’s Department of Emergency
Medicine, Administrator Peter Forster says there are weaknesses in preparedness for
terrorist attacks.


“We’ve made a lot of progress from where we were, but we’ve got a long ways to go.”


Forster says when victims start showing up at the hospital emergency rooms…. there will
be bottle-necks…


“Most emergency preparedness activities have been geared toward local events with
relatively small numbers of victims. When we start talking about hundreds of people or
thousands of people injured or hurt, or exposed to some toxic or contagious substance,
then I think the health system would have a significantly difficult time expanding to meet
that requirement, regardless of how much, uh, how well we’re trained or how prepared
we are. We don’t really have the capacity on the health care side to manage a significant
influx of patients.”


Forster says plans to set up emergency medical facilities in auditoriums, school gyms,
and maybe even hotel rooms need to be completed… arrangements made… and supplies
stockpiled.


(sound up of training exercise, generators, etc.)


Meanwhile, back in Detroit… investigators are putting on bulky chemical protection
suits—the ones that look like big space suits…blue, yellow, olive, with teal-colored
gloves and orange boots… you’d think of circus colors if the subject matter weren’t so
serious. After examining the mock lab, spending about an hour in the sweltering suits,
they come out for decontamination before their air tanks run out. The local agencies help
with decontamination… spraying and scrubbing the suits down.


(sound: beeping, scrubbing)


The training site has all the sights and sounds of a real emergency. Lots of emergency
vehicles… the noise of generators and the smell of diesel. But it’s fairly relaxed. There’s
none of the tension, none of the urgency of a real emergency.


The U.S. EPA’s On-Scene Coordinator, Mark Durno, says there are some things you
can’t bring to a drill…


“You can never simulate the adrenaline and the potential panic that’s associated with a
real event, especially when you hear the words ‘chemical’ and ‘radiological’ agent.
However, we can practice those little tools that we’re going to need to be absolutely
proficient at to ensure that when the panic hits, we’re ready to roll without any
hesitation.”


The days’ training has turned up a few glitches. Communication between agencies is
still a problem. Emergency radio frequencies need to be sorted out and coordinated. And
there are still some major gaps in preparedness that are not part of this training… such as
the emergency room capacity problem. But one of the bigger issues is money. Federal
money has been promised to local governments… but it’s been very slow in coming.

School Connects Kids to Healthy Eating

American kids are overweight. Nutritionists say one major reason
is that kids are eating too much junk food, and not enough fresh
produce. A government pilot program is trying to get kids
to eat more locally-grown fruits and vegetables in school by giving them out
for free. The Great Lakes Radio Consortium’s Rebecca Williams
visited a school where the experiment is underway:


It’s 9 am and the halls are quiet at Everett High School, in Lansing,
Michigan. Parent volunteers are setting out bowls of bright
pink grapefruit segments on stands in the hallway.
They’re working quickly, getting ready for 1500 hungry teenagers.


(bell rings, noisy chatter swells, sneakers squeaking)


Kids slow down when they pass the fruit stand. A few kids take a bowl…
but not that many.


“Ain’t nobody want no grapefruit?”


(kids chatting)


“They’re hesitant to try it because it’s new, they’ve never tasted grapefruit
before.”


(final bell ringing under)


Lynn Beard is energetic. When she’s not handing out
fruit, she’s teaching nutrition here at the school.
As much as she talks to kids about their choices, even she can’t predict
what they’ll eat.


The hall empties. Lynn Beard sees a few stragglers.


“Sir, have you ever had grapefruit, honey, before at home? Yes,
okay.”


She pulls Brandon Washington over to the fruit stand…


“He was going to try it, and he put it back down because someone said it
was sour.” B.W. :”I was going to try it.”
“Honest reaction?”
“Honest reaction? Tastes like it needs some sugar in it.”


Even though he’s not a grapefruit fan, Washington says he likes having
the fruit and veggies here.


“Now that they got them at school, I eat it more. And that’s good,
too, because nutrition values, good for your soul, you live longer, right?”


Washington says, before he could get free fruit and vegetables during the day,
he felt hungry between meals. Many of his classmates skipped breakfast.


Lynn Beard worries about her students’ eating habits.


“English, math, social studies, aren’t changing the obesity rate. Early
onset osteoporosis, we’re seeing a huge jump in. Type two diabetes in children.
What are we doing to educate our kids on how to change? Isn’t that an effective
place to use taxpayers’ dollars?”


That’s one of the questions behind the Fruit and Vegetable Pilot.
It’s a year-long experiment, funded by 6 million dollars from the 2002 Farm
Bill.


107 schools in Michigan, Ohio, Indiana, Iowa and New Mexico were
chosen. It’s a mix of schools: large and small, rural and urban.
The hope is that kids will learn to like fruits and veggies… and be
cultivated into new consumers.


Agriculture promoters hope one of the spin-offs will be a new market for
local farmers. With few exceptions, the pilot program requires that
schools buy only American produce, and local produce if
they can. Fourteen of the pilot schools buy directly from farmers.


Everett High School gave kids some locally grown produce. But Lynn Beard
says the kids still don’t know much about the food that grows where they live.


“Kids don’t understand seasonal fruits, they were so upset we weren’t
getting watermelon in January. ”


And Beard says just getting local produce at all was difficult.
Schools such as Everett High School buy from national food service
companies. The companies often sell these Michigan schools
Washington apples.


Marion Kalb directs the National Farm to School Program. It’s
part of a non-profit group that works to connect farms
and schools. Kalb says food service companies don’t make a
special effort to buy from local farms.
But she thinks schools can influence their suppliers.


“If there’s instruction on the school side to say, you know we’d like
to know seasonally what’s available locally, then that gives incentive
to the distributor to try and make buying from regional or local farmers a
priority.”


And it makes sense to most people to sell apples nearby rather than shipping
them miles away.


(birds twittering in open air market, people talking about flowers)


In a farmer’s market full of flowers, Dwight Carpenter is one
of the few farmers selling produce this early in the year. That’s because
he grows vegetables in a greenhouse.


He sells at two farmer’s markets and a store on his land. He says it’s enough to survive,
but he’d like to expand to places such as local schools.


“It’s kind of a difficult way to make a living, and if better markets were
established, such as schools and hospitals, and that kind of thing,
grocery stores, and if that were turned around, that would help the farmer too,
to be able to hang onto whatever he’s got, rather than to have to sell it off to subdivisions
or whatever.”


(birds out)


(sound up: cafeteria, “Let me know how you like the spicy chicken sandwich.
It’s new.” cash register beeping)


Although the kids at Everett High School are getting used to eating more
produce from the free program, you won’t find many fruits and vegetables
for sale at the cafeteria. That’s because the cafeteria competes with nearby fast food
restaurants.


You also won’t find many nutritious snacks in the vending machines. The school needs
the revenue it gets from the candy bars and chips.


Kids are still lining up at the soda machine today. But some students
think the fruit and veggie program is slowly changing their eating
habits. Wynton Harris is a sophomore.


“Last year everyone was eating junk and this year they cut down a lot. I
can tell, because I’m seeing less people at the machines, and more
people taking fruit. And I said, wow.”


And Everett High School’s nutrition teacher, Lynn Beard, has a vision: vending
machines that offer fresh produce instead of potato chips.


“If there’s nothing free, I think we’d have a number of kids who, instead of buying
a dollar pop, would buy a dollar pear.”


The free fruit and vegetable program ends with the school year. But some 70 schools
in the U-S buy from their local farmers even without special federal funding.
Even so, Lynn Beard doubts her school could afford to keep this program going
without federal money.


“I think next year I’m not going to want to be around here without this
grant, cause there’s going to be so many complaints. Where’s our fruit? Why
can’t we get some fruit? I’m dreading next year. I’m just going to have to keep a smile on
my face and say, “Talk to your government.”


But government support for the program is uncertain.


Congress will debate the future of the fruit and vegetable program. And whether
government should be marketing fruits and vegetables in the schools… and further
subsiding the farmers who grow them.

Pitfalls of Spraying for West Nile Virus

The West Nile virus has claimed 28 lives and at least 550 people have been infected in the nation so far this summer. And evidence of the virus has already been found in 41 states. The carriers of the virus, mosquitoes, have been a concern and a nuisance for public health officials. Many citizens are demanding more visible action on the officials’ part to get rid of the bad bugs…like spraying chemicals to kill adult mosquitoes. The Great Lakes Radio Consortium’s Annie MacDowell reports:


You might not expect to find a breeding ground of controversy in the suburbs, but
then again, you wouldn’t expect to find an exotic disease breeding there, either.
With the West Nile virus threatening any place that has mosquitoes…which is almost
anywhere…people are fighting over whether to spray or not to spray.


Spraying means releasing pesticides into the air to kill adult mosquitoes.
Pro-sprayers say the threat of West Nile virus necessitates this chemical
treatment. But some people who live in spraying districts are worried about the
possible dangers of the pesticides. Dr. Kim Stone is the Executive Director of the
Safer Pest Control Project in Chicago. As we walk around a nature preserve, she
tells me they’ve started spraying in her neighborhood and she’s worried about her
kids. Passing the pond and a grove of trees, she says the pesticides could kill fish
that eat mosquito larvae and birds that eat the adults. But she’s more concerned
about their possible threat to humans.


“I believe that the health impacts of the pesticides are a greater danger than the health impacts of West Nile virus. A local hospital had seen many people who thought that they had West Nile virus, came in with headache, nausea, and the hospital said that they did not have West Nile virus, but suspected that it might be related to the pesticides, because it was the morning after pesticides were sprayed in those neighborhoods.”


Stone recommends a different form of mosquito abatement…larvaecide.
Larvaecide is a preventative form a treatment that kills mosquito larvae before they
hatch. Pellets of larvaecide are dropped into lagoons, or a blower is used to spread
granules over the water. The chemicals are less toxic, she says, and they’re
species-specific. That means they won’t kill other animals. Dr. William Paul is with
the Chicago Department of Public Health. He says the city of Chicago hasn’t started
spraying because larvaecide is much more effective.


“We would really, in terms of mosquito control, want to focus on the long run,
breeding sites, and larval breeding sites, because that’s in the long run what’s going to be more effective. Using sprays for adults to kill the northern house mosquito… it’s challenging, you need tightly spaced applications of the product. And it’s not just a going up and down the streets kind of thing.


But spraying is a more visible treatment than larvaecide. Paul says people like to
see their government doing something to combat the mosquitoes. It makes them
feel better, he says. Other government officials can relate. Dr. Kiahn Liem has
been the head of the South Cook County Mosquito Abatement District in the Chicago area for 28 years. He’s has been working with mosquitoes since he was a little boy. He says watching many of his fathers’ patients die of malaria in his native country led him to his current profession of killing mosquitoes.


“I grew up in Indonesia, and malaria is a big killer of people there. Almost six to ten million people every year get killed by malaria. And there’s probably ten times more mosquitoes there than here.”


Liem uses larvaecide in his district. He hasn’t sprayed since 1977, after the
outbreak of St. Louis encephalitis, another virus carried by mosquitoes. He says
spraying was not effective then, and it still isn’t now, as most mosquitoes hide out in
people’s back yards, in the bushes or under leaves. He says the spray released from
trucks in the street just doesn’t reach them. But many of his citizens demand a
visible fight against the mosquitoes.


“They want to see you working. But if you work and you don’t do anything for them, you’re just fooling them. We have many of them that call us, and say, I want you here, I want you to show me that you’re doing something for my money. And we do that just to appease them.”


If people really want peace of mind, personal protection is what most experts
recommend. They say to wear long sleeves and pants between dusk and dawn
when mosquitoes are out in force. If you’re going outside, use mosquito repellent.
And routinely change standing water on your property, such as kiddie pools and bird
baths, to cut down on available mosquito breeding sites.

Cooling the City With Green Rooftops

On the nightly TV news in large cities, the meteorologist sometimes talks about the heat island effect. That’s where all the blacktop roofs and asphalt parking lots soak up the heat and increase the temperature on a hot summer day. One major U.S. city is trying to do something to reduce that effect. To set an example, the mayor decided to start with City Hall. The Great Lakes Radio Consortium’s Lester Graham reports:

On the nightly TV news in large cities, the meteorologist sometimes
talks about the heat island effect. That’s where all the blacktop roofs
and asphalt parking lots soak up the heat and increase the temperature
on a hot summer day. One major U.S. city is trying to do something to
reduce that effect. To set an example, the mayor decided to start with
City Hall. The Great Lakes Radio Consortium’s Lester Graham reports:


Standing on the roof, eleven stories up, isn’t really far enough to escape
the noise of the city below. But this rooftop is an escape. It’s a garden, a
big one. There are even trees. Not in pots, but actually planted on… or…
in the roof.


Marcia Jiminez is the Commissioner of the City of Chicago’s Department of Environment. She says Chicago wants building owners to
do what they can to cool the city down… and planting gardens on the
roof is one way to do it. So that’s what the city did on top of City Hall.


“Well, the garden on the rooftop is addressing what we call an urban heat
island problem. By putting the garden with light colored pavers and the
green plants on top of the roof, we’re actually helping to use less energy
inside the building and it actually helps to keep the building cooler.”


Cooling down the building is just the beginning of this garden. Despite
being eleven stories up in the middle of downtown, the roof is alive with
bugs and butterflies.


“Actually birds and all of the insects, many of them, have found their
way up here. We’ve actually put up birdhouses to study what kind of
birds are coming to the rooftop garden. This is a place of
respite as well as a place to feed.”


The whole rooftop has become something of a lab. Scientists research
what animals have made a home here… and they’re monitoring how the
plants are spreading.


Kimberly Worthington worked on the City Hall project to see it go from
the drawing board to rooftop. She says they chose plants for color, form
and for survivability.


“The design that we went with was low maintenance, was what we were
looking for in our plant selection. And the landscape architects that were part of the design team focused on plants that would require less water. And they also wanted to keep as many native plants as possible. So, there are a lot of prairie plants up here.”


The Chicago City Hall rooftop project also reduces rain water runoff. 75-percent of a one-inch rain will be soaked up right here in the garden. That’s good because too much rain overflows sewers into Lake Michigan. If enough buildings in the city had rooftop gardens, stormwater runoff problems would be curtailed a bit.


While the city is touting the environmental benefits of its rooftop garden, in another part of the city a planned rooftop garden is all about people.


Brenda Koverman is with the Schwab Rehabilitation Hospital in Chicago. We’re up on the roof where she’s showing me landscape renderings of how the surrounding area will look once the planting begins. Stone paths, fountains, flower gardens and shrubs.
It’ll look beautiful. And it’ll probably cool things down up here. But Koverman
says this is for the patients who are learning to be mobile after disabling injuries. The hospital hopes that patients in rehabilitation will find the rooftop garden more pleasant and helpful than institutional tile floors and plastic obstacles as they learn to
manuever…


“You know, so, are patients more able to maneuver their wheelchairs in the community? Are patients able to use their hands better so they can cook better at home? Are patients able to stay out of the nursing home and go to their home? So, if we can get any kind of
those outcomes, then it’s a huge success.”


It might be more interested in the patients, but the hospital will still be helping Chicago reduce its heat island effect.


There aren’t very many of these projects in the city, so it’s hard to say whether the rooftop gardens could cool things down all that much. But Environment Commissioner Marcia Jiminez says all you have to do is go up on the roof on a hot day. City Hall sits right next to the County Building. In fact they look like the same building. But not from the roof. Only one side is garden.


“In last summer in 2001 on the hottest day, while it was about a hundred degrees on the city hall side, it was 165 on the opposite end of the building where’s there’s a blacktop roof.”


Even if you’re not interested in planting a garden on your roof, the city still requires some effort to cool things down. City ordinance calls for light colored material when a roof is replaced. And parking lots have to plant some trees before they can get a permit to resurface. Rooftop gardens aren’t mandated… but city officials say they’re learning first
hand that it’s a much better use of space in the city.
