Green roofs are increasing in popularity across the US, especially in cities, where
there’s not a lot of space for gardens. Sabri Ben Achour explores the trend in
Washington, DC, where the city government is promoting the practice for it’s
environmental benefits:

In Washington, you can see flowers and vegetables growing on top of homes,
businesses, even government buildings throughout the city. DC officials say
Washington has nearly 70,000 square feet of rooftop greenery. Only Chicago has
more.

One big fan of these so called green roofs is a popular small hotel, Tabard Inn, just a
few blocks from the White House.

“There’s about 10 varieties of sedum on this roof.”

Sarah Murphy is giving a tour. She’s a horticulturalist.

“This is a very pungent oregano here on the corner, it looks heavily used.”

The city of Washington pays building owners about one-fourth of the cost of
incorporating greenery on rooftops. One big reason? Rainwater runoff.

Sarah Loveland works for an environmental consulting non-profit called DC
Greenworks.

She says Washington has what’s called a combined sewer system. The sewer
system doesn’t just take in what’s flushed down the drain, but also all the rain
running off roofs and streets.

“If you imagine that our sewage treatment plant has a dam, and the sewage system
combines with the storm water system before the treatment plant.”

So, when there’s a heavy rain, that dam at the sewage treatment plant overflows.

“You have both raw sewage and runoff from the streets going directly into the river
untreated.”

Three billion gallons of it a year, at one point.

The EPA sued the District of Columbia.

The city had to spend $150 million to address the problem. Part of that money goes
to green roof grants.

The green roofs slow down rain water – give it some place to soak instead of just
running off straight down the gutter. The city says roofs in the city prevent a million
gallons of storm water runoff from entering the Potomac River.

The roofs also insulate buildings – especially during the summer. Some studies
show they reduce energy costs by 20-30%. And they reduce the heat island effect in
the city, since they don’t get blisteringly hot like traditional roofs.

Green Roofs even offer some habitat for creatures, like bees.

Sarah Loveland with Greenworks, the consultant agency, says rooftop gardens are
also increasingly popular for growing food.

“Veggies are really popular, herbs are really popular – this is a trend that’s taking off
in the restaurant industry. There’s a lot of buzz around it.”

Blueberries and herbs abound in the rooftop gardens of the Tabard Inn, where Paul
Pell is executive chef.

(sound of celery chopping)

“Yeah, we go up and get whatever we want, so it’s fresh. We just climb out the
window when we need it. Chocolate basil goes with ice cream, nasturtiums go with
soups and salads.”

Washington has an advantage over some larger cities in its promotion of rooftop
gardens because federal law prohibits skyscrapers in the nation’s capital, so most
buildings don’t cast shadows over their neighbors.

As a result, most rooftops are sunny – all they need is greenery to soak up the rays.

Sending a City’s Garbage Up in Flames

Back in the 1980s and 90s,
dozens of communities across
the US built incinerators to
get rid of their trash. Many
of them financed the massive
furnaces with bonds they’re just
now paying off. And now that
those debts are off their books,
some cities are re-thinking whether
burning trash makes environmental
and economic sense. Sarah Hulett reports:

About 300 garbage trucks dump their loads each day at the nation’s biggest
municipal incinerator.

“You see the conveyor house going across, that’s conveying the fuel to the
boilers.”

That’s Brad Laesser. He’s the chief engineer at the Michigan Waste Energy
facility in Detroit.

The “fuel” he’s talking about is shredded-up trash.

And he says that’s the beauty of facilities like this. They produce electricity.

“So right now we’re putting out about 50 megawatts. But we can go to
here.”

Laesser points to 70 on the output gauge. That’s enough electricity to power
about half the homes in Detroit. And the leftover steam is used to heat and
cool more than 200 buildings downtown.

Sounds great, right?

Well, Brad Van Guilder of the Ecology Center says not so much.

“Be wary of people coming and talking to you about large, expensive magic
machines that are going to dispose of your waste for you.”

Van Guilder says municipal waste incinerators are major contributors to
smog, and spew dangerous pollutants like dioxin, lead and mercury.

And he says huge furnaces like Detroit’s make it nearly impossible to get
viable recycling efforts off the ground.

“Think about what’s in the trash that you throw out every day. One of the
most important components is paper and plastic.”

Both can be recycled. But Detroit has not had a curbside recycling program
for the past 20 years. That’s because the contract with the incinerator
required that all trash picked up at the curb be used to keep the furnaces
burning.

That changed this summer, though – when the contract expired. Now about
30,000 households are part of a curbside recycling pilot project. And there
are drop-off sites where people can take their recyclables.

(sound of recycling center)

Matthew Naimi heads an organization that runs several drop-off sites, and –
maybe surprisingly – he’s okay with the incinerator. Naimi says he sees
trash disposal and recycling as two separate industries.

“I realized that if we shut the incinerator down before we got a good
established recycling program running, we’d be burying our recyclables
instead of burning them.”

And officials with Covanta – which runs the Detroit incinerator – agree that
recycling and incineration can work together.

Paul Gilman is the chief sustainability officer for Covanta. He says landfills
are the problem – not recycling.

“Landfills and energy-from-waste facilities, that’s where the competition is.
It isn’t at the upper step of recycling.”

He says cheap landfill space makes the economics of incineration difficult.

But he’s hoping that could change with the passage of a climate change bill
in Washington. Gilman says in Europe and Asia, trash incinerators like
Detroit’s don’t get treated the same way as power plants fueled with coal or
natural gas.

“So in Asia, under the Kyoto protocols, a facility like this actually generates
what are called greenhouse gas credits. They’re reducing greenhouse gasses
by the act of processing solid waste and keeping it from going to a landfill.”

Where trash produces methane – a potent greenhouse gas.

But the people who want the incinerator shut down say they don’t believe
burning trash is the greener way to go. They want the city to landfill its
waste while it builds an aggressive recycling program.

So far, they’re not getting what they want from city leaders.

The board that oversees how Detroit handles its trash recently voted to go
with incineration for at least the next year.

San Francisco already leads the
nation in recycling. Now, that
city has the first mandatory
composting law in the country.
Emily Wilson reports that’s got
some people worried about “garbage
cops”:

Putting recyclables into the blue bin is second nature for people in San Francisco.

But this new law now means also putting coffee grounds and eggshells into a green bin.

There are some people who are concerned about Big Brother looking through their garbage. And then there’s the $100 fine.

Mark Westlund at the Department of the Environment says ‘no worries.’ Not much is going to change.

“Well, we get a lot of calls from people who are worried about garbage cops and that frankly is not going to happen. For years now we’ve been looking in peoples recycling to make sure they’re doing it correctly and if not, they get a tag and if they continue misusing it, they get a letter and a follow up call and then a visit.”

So there are warnings before the fine.

Cities across the country will be watching San Francisco’s mandatory composting law to see how it goes.

Turns out there’s more to childhood
obesity that junk food and bad genes.
A national group of doctors places
some of the blame on urban design.
Jennifer Guerra has more:

The American Academy of Pediatrics puts out so-called ‘policy statements’ all the time. Usually they’re for other doctors to read.

But this time, the doctors group is taking aim at lawmakers.

The group issued a statement in Pediatrics Magazine that basically says urban sprawl is one of the main causes of childhood obesity because often kids can’t walk to parks or schools.

June Tester is the lead author. She says the statement was a little controversial within the group.

“A lot of time, physicians are too busy or feel uncomfortable about being in the role of an advocate. But it’s a shame, because when physicians are actually motivated enough to speak to legislators, it can actually make a big difference.”

Tester says the response from the urban planning community has been really positive. Now she hopes lawmakers keep the research in mind when it comes time to vote for legislation that will affect a community’s design.

Sea Levels Threaten Coastal Towns (Part One)

It’s beach weather – and along the mid-Atlantic one of the most popular beaches is Ocean
City, Maryland. For years, engineers have been battling back the ocean to save the beach
and the town. And as Tamara Keith reports, that fight is only going to get tougher and
more expensive if predictions of sea level rise from climate change become a reality:

It’s beach weather – and along the mid-Atlantic one of the most popular beaches is Ocean
City, Maryland. For years, engineers have been battling back the ocean to save the beach
and the town. And as Tamara Keith reports, that fight is only going to get tougher and
more expensive if predictions of sea level rise from climate change become a reality:

When the sea level rises, Ocean City feels it. It’s on the front lines – a barrier island on
the edge of the Atlantic.

(sounds of water)

Terry McGean is the city engineer for a town he describes as a working class resort.

“Our industry is tourism, and the real reason people come here is the beach.”

But in the 1980s, that beach was reduced to a narrow strip. Not so today, all thanks to a
massive, and expensive, beach replenishment project. In 1991 countless tons of sand
were brought in, dunes were built. But that wasn’t the end of it.

To keep up with erosion, McGean says the beach here at Ocean City has already been re-
nourished 4 times.

“Approximately every 4 years we’re doing a re-nourishment project. To give you an idea
of the scale, that’s 100,000 truck loads of material that we’ll put on here. Though it
doesn’t actually come on a truck? No. It’s pumped in a dredge from out in the ocean.”

It is a constant fight, because the waves keep coming, keep pulling the sand back out to
sea. Scientists say this is partially just normal erosion. But some of it at least can be
blamed on global climate change and sea level rise. Over time, they say, the share of the
problem caused by climate change will grow.

“If you hadn’t done the beach replenishment do you have any sense of what this would
look like right now. There probably would have been no public beach left in many of
these areas.”

So far fending off the sea has cost $90-million, split amongst local, state and federal tax
dollars. But engineers estimate some $240-million in storm damage has been prevented.

“Holding back the sea is an economic proposition. If you’re willing to spend the money,
the sand exists to elevate any given barrier island.”

Jim Titus is the project manager for sea level rise at the Environmental Protection
Agency. And he’s been sounding the alarm about climate change for years. And he says
policy makers and the public will eventually have to decide which beaches, which
communities are worth saving.

“The challenge for communities like Ocean City is to persuade everyone else that they
are one of those cities that are too important to give up. And then to get their residents to
cooperate in doing what it takes to do to gradually elevate the entire community with a
rising sea.”

But if you think in geologic time, like University of Maryland professor Michael Kearney
does, there isn’t a whole lot of hope for barrier islands like Ocean City.

“It’s essentially a pile of sand. There’s really nothing permanent about it.”

Kearney studies coastal processes.

“The long term prospect of any barrier surviving the projected rates of sea level rise, even
at the moderate rates – the so-called moderate rates, that the IPCC predicted is pretty
slim.”

Ocean City engineer Terry McGean just isn’t buying it. He thinks Ocean City can survive
sea level rise.

“I think that we can design towards it and we can probably build towards it and with
responsible actions we can live with it.”

As long as there’s enough sand and money to keep it going.

Sea Levels Threaten Coastal Towns (Part Two)

Scientists are pretty certain climate change is going to cause the sea level to rise. It’s
happening already, actually. In communities around the Chesapeake Bay, people are
getting a sneak preview. Tamara Keith reports some people there are trying to work with
nature rather than resist it:

(sound of kids planting)

It’s been raining in Woodland Beach. The community is just off of the Chesapeake Bay
in Maryland. The ground here is so soft you sink into it. Mud is everywhere. And that’s
just fine with the volunteers planting native grasses on a sloping hillside.

Stephen Hult is trying to keep things in order.

“And when we plant them we want them all the way down. I’m telling everyone twice.”

Hult heads up shoreline restoration projects for the local property owners association.
And there’s a lot of shoreline to restore.

“The shoreline, in parts of the community since the 1930s, have eroded 20 feet. Year to
year, one barely notices, but if you look at aerial maps of what it used to be like
compared to what it is, it really is quite dramatic.”

There’s been tons of erosion here. The land all along the mid-Atlantic coast is also
slowly sinking. Combine that with global sea level rise and you get erosion in overdrive.

Hult says the community is trying to restore the beach with rock and dirt and sand and
grasses to hold it all together. This is what’s called a living shoreline.

“We have now, with this project it will be well over half a mile of living shorelines that
we’ve installed.”

It’s a relatively new concept, a more natural approach to the gnawing problem of
shoreline erosion. Living shorelines create buffer between the water and homes. They are
kinda like the tidal wetlands that used to be here – before property owners started building
sea walls, also called bulkheads.

Jana Davis is associate director of the Chesapeake Bay Trust. It’s one of the organizations
funding this shoreline restoration. And Davis also happens to live here.

“It’s a wonderful alternative that provides just as good shoreline protection while also
providing a lot of really important habitat benefits that a bulkhead or rock sea wall does
not provide.”

Good for wildlife, and she says, it’s adaptive in the face of sea level rise.

“If sea level were to rise another foot, for example. The marsh could kind of migrate
inland, whereas if you had a bulkhead obviously there’s no migration because it can’t
move.”

But most of the people with bulkheads are NOT buying it. They want to protect their
property from the sinking land and rising water, and a lot of them don’t think a bunch of
rocks and grass are going to cut it.

Kevin Smith is chief of restoration services for the Maryland Department of Natural
Resources.

“There’s many places you can go and look at miles of shoreline and not see any natural
shoreline at all. It’s all armored off.”

Smith met me at a nature center along the bay. A few years ago, a stretch of bulkhead
here was replaced with a living shoreline. The natural ebb and flow of these shorelines
has made some property owners skeptical. They want the shoreline to stay put.

“If these types of projects don’t protect that shoreline from erosion, then homeowners are
not going to want to do it.”

But Smith insists these projects do work, and long term they’re going to be more
sustainable and more flexible than bulkheads – which over time will lose the battle
against the constant pounding of the rising sea.

Cities Share Cars to Save Cash

Car sharing has long been considered a green
alternative to owning a car. Both in terms of
expense and the environment. Companies like
Zipcar have made this concept mainstream in
a lot of urban areas. Now some cities are
trying out car sharing with their municipal
fleets. Tamara Keith has more:

Karyn LeBlanc works in the Washington DC department of transportation, so maybe it’s not surprising that she was one of the first to try out the city’s FleetShare program.

“It’s this one over here, right here, says 6067 is the license plate on it.”

A white Honda Civic powered by natural gas is waiting for her in a parking lot behind a city office.

She went online to reserve the car and it’s expecting her. At least the very smart computer transponder thingie in the front windshield is expecting her. LeBlanc presses something that looks like a credit card up to the device.

“So, we place this right here and you hear that little click and the car opens.”

The tank is full, the keys are inside, and LaBlanc is off and running.

(sound of driving)

“I would say I use fleetshare 2 or 3 times a week for any meeting that I need to go to or that I need to get to. So I go where I need to go. I park it. I go to my meeting. I get back in the car and I go back to the office.”

For people who use Zipcar this process will sound very familiar. The company has simply brought its car-sharing technology to Washington DC’s municipal fleet.

So far DC has about 60 new cars outfitted with Zipcar gear. But here’s the remarkable thing, those 60 cars are replacing 360. How? The new cars are getting a lot more use than the old ones.

“We’re getting up to 71% utilization on all these cars.”

When we spoke to him, Dan Tangerlini was DC’s Deputy Mayor.

We’re standing in the middle of a municipal parking lot. On one side there are empty spaces where the fleetshare cars park – on the other side there are just a bunch of white city cars.

“You see all this white iron around here. All these DC government vehicles that are kind of sitting static because these are assigned to individuals and those individuals don’t have a reason to be in that vehicle right now.”

Tangherlini says this system will save the city about 6 million dollars over the next five years – which is welcome at a time when budgets are tight.

Which might explain why Scott Griffith’s phone keeps ringing. He’s Zipcar’s CEO and says the company is now in talks with 25 cities.

“They all have the same challenges, not enough tax money, too many cars. They do need to move people around during the day and we’re trying to make that happen in the most efficient way.”

But this isn’t just about money. Griffith says when people share cars they end up driving more efficiently. When they have to book in advance rather than a bunch of individual trips they stack all their stops in one trip.

Car sharing isn’t new for cities like Chicago, San Francisco and Philadelphia. They’ve had programs in place for some time where city workers can use cars loaned out by private car sharing companies. They use the same one the public uses.

Eli Masser helped form the relationship in Philadelphia between the city and the non-profit Philly Car Share which he co-founded.

“One of the benefits of car sharing with municipalities or most businesses for that matter is residential demand is in the evenings and on weekends and most business demand and municipal demand is during the day.”

Which means those cars are busy well beyond the 40 hour work week. Critics say this model is far more efficient than what Zipcar is doing in DC. But Masser says there’s an even better model – a hybrid of DC and Philly.

Ideally cities would have a relatively small city-owned fleet of shared cars and even heavy machinery. But most city workers would car-share with the public.

This week, one state is voting on a bill that would make it illegal for restaurants to serve takeout food in styrofoam. Rebecca Williams has more:


A number of cities have banned Styrofoam food containers – including San Francisco, Seattle and Portland. And now California lawmakers are deciding whether to ban the containers.


The bill says styrofoam is a big litter problem. And animals can choke on pieces of it.


The World Health Organization’s cancer research agency says styrene is a possible human carcinogen. Styrene is the stuff styrofoam’s made out of.


Jerry Hill is the Assembly member who introduced the bill in California. He says the American Chemistry Council and other groups are making it hard for him to get the votes he needs.


“You would think the world was going to come to an end if we were to prohibit and ban Styrofoam. It’s an industry that whether you look at the chemical industry, the restaurant industry that’s opposing it, and they are very vocal and very powerful.”


The opponents say there’s no reason for the ban, and they say it would be bad for the economy.

Growing a City in a Greener Way

For many small town mayors, growth is all good. After all, more houses means more tax revenue, more retail, more jobs. One Alabama mayor agrees, but he also recognizes green space is an amenity worth keeping. And for that, the timing couldn’t be better. Gigi Douban reports:

Here at the grand opening of a subdivision in Trussville, Alabama, a few dozen families gather outside the sales office for the usual ribbon cutting with giant scissors.

(sound of applause and cheers)

Soon, everyone heads down to the Cahaba River. The river literally will be in the backyard of these houses once they’re built. On the river, they’re having a rubber duck race.

(announcement of duck race)

It’s gimmicky, but these days developers will do just about anything to attract potential buyers.

Another developer had approached Trussville about building homes along the Cahaba River, but then the housing market took a nose dive. The developer wanted out.

Trussville Mayor Gene Melton says the city would have been crazy not to buy the land.

“This property was probably going to sell for $35,000 or $40,000 an acre. We got to the point where we were able to acquire this for $4,500 an acre.”

The city could have turned it into an industrial park or zoned it for retail. But instead, they’ll turn it into a greenway. It’ll connect to nearby parks with the river as the centerpiece.

Now, the mayor of Trussville is not a staunch environmentalist, by any measure. He tools around the city in a gas guzzling SUV. He’s pro-development. But, he says, the same way a city needs development, it needs greenspace, too.

“Have you ever flown in to a big city like Atlanta or Los Angeles and for miles and miles all you see is rooftops? Well that’s how not to build a city.”

The Cahaba River watershed stretches through Alabama’s most populous county. Recently, heavy development along the Cahaba has polluted the water. It’s endangered habitats not just here, but downstream. Trussville is very near the headwaters, so what happens there affects the entire river.

Randall Haddock is thrilled about the new greenspace. He’ a field director with the Cahaba River Society, a conservation group. Haddock says the Cahaba River is among the most biologically diverse in the country.

“It turns out that Alabama has more fish species, more snails, more crayfish, more turtles, freshwater snails more than any other state in the US. So when it comes to things that live in rivers, we’re at the top of the list by a long way.”

(sound of people walking near river)

Haddock says all along the Cahaba, he’s seen plenty of examples of how not to build near the river.

He says this greenspace is an example of how easy it is to minimize impact. Keeping grass on the ground not only means a cleaner river, but it might help reduce flooding.

“When you make so many hard surfaces, the water runs off real fast and gets into the river real quick. And you’ve increased the volume of water and the only response that a river can make is to get bigger.”

The bank erodes, the water is polluted and soon, you start to see species diminish.

(sound of high school students)

David Dobbs is the city’s high school environmental science teacher. He takes his students out behind the school to check on the river. The result: a clean bill of health.

“All the little bugs, they end up being food for the fish, and the more they are of the good ones that are here, that means there’s more food for the fish, so therefore there’s more fish, it’s a very healthy part of the river.”

Trussville, like many small towns, still says without growth, there’d be no city. But now they know, that growth has to protect one of its top amenities – the river.

How Green Is the LEED Label?

  • LEED buildings get points for green things like bike racks and good energy use, but it doesn’t actually enforce energy efficiency (Photo by Lester Graham)

The biggest energy users in America are not cars and trucks – they’re buildings. Buildings use about 40% of the nation’s energy.

The biggest energy users in America are not cars and trucks – they’re buildings. Buildings use about 40% of the nation’s energy. In 2000, the US Green Building Council introduced a program that certifies “green” buildings. It’s called LEED. That stands for Leadership in Energy and Environmental Design. A new version of the LEED standards is being released today, April 27. But Samara Freemark reports some critics see serious flaws in the LEED program:

Before LEED came around in 2000, developers didn’t really spend a lot of time worrying about whether their buildings were green. They were designing and constructing buildings they could market. Green just wasn’t a priority.

“It was always the last thing on the agenda for the staff meeting, because nobody really understood what success looked like.”

Brendan Owens is a LEED spokesman. He says the people who came up with LEED wanted to change the culture of building in America. Make building ‘green’ marketable.

And they realized that to do that, they’d have to define what a green building looked like.

So they created a checklist. Install solar panels and you get points. Bike racks: more points. Get a green roof – somewhere you can grow plants — add some points.

Enough points and the developer gets a LEED certification. Certified buildings get a plaque. Developers get the PR boost that comes from building green. The public gets a more sustainable building. That’s the idea, anyway.

The program really caught on. More than 10,000 projects are currently going through the LEED process. And universities, municipalities, even the federal government are writing the standards into their own codes.

But critics say the system might be spreading too fast.

“The people who are writing the LEED Standards are in effect writing our country’s most important laws.”

That’s Henry Gifford. He’s a building engineer in NYC. He’s also one of LEED’s most outspoken critics.

Gifford says it’s possible to earn LEED certification – and cash in on the PR benefits of being green – without actually fixing a building’s biggest environmental problem.

“The 3 most important things to make a building environmentally friendly, are energy use, energy use, energy use. All the other things in the LEED checklist, which I think are wisely chosen and very important, they pale in comparison to the energy use.”

The LEED checklist does give points for good energy use- a lot of them, actually. But it doesn’t enforce energy efficiency.

Instead, developers win points by predicting their buildings will perform well. Developers do have to submit energy use data once their building is up and running. But if the building turns out not to save any energy? Brendan Owens says…

“What we do, is we notify the building that they’re not performing up to their potential.”

But no one’s coming around to unscrew that accreditation plaque. The building gets to keeps its certification.

On average LEED buildings seem to do better than others on energy use. But there are plenty of LEED-certified buildings that do use more energy than comparable non-certified ones.

Gifford says that’s unacceptable. No energy hogs, no matter how many bike racks or green roofs they have – should be allowed to call themselves green.

“It’s a scandal to have any underperforming building win or retain a rating for being green. I’m sorry. Every building labeled as green should have very good energy performance. Until we get there, we’re making believe.”

LEED doesn’t claim that certified buildings are perfect. Instead, Brendan Owens says the standard is meant to provide a holistic measure of greenness.

“I’ve heard LEED certified buildings described as sustainable. And there are a few, but the lions share of those projects haven’t achieved it. But that doesn’t necessarily mean that the rating system is flawed. It just means that people are misunderstanding what it’s about.”

In other words, people are reading more into certification than they should. Critics like Henry Gifford worry that will lead to complacency when it comes to truly greening buildings.
