Not all heat island effects are
the same. But, Rebecca Williams
reports, NASA scientists have
found there’s one thing all cities
can do to cool things down:

The NASA scientists found the heat island effect is much less intense in hot, dry parts of the country.

A city like Las Vegas is actually cooler than the desert, because of all the lawns and trees inside the city. And a city like Chicago is hotter than the tree-lined suburbs surrounding it.

It’s all about trees. Shady trees cool things down.

Lahouari Bounoua is one of the researchers.

“One of the most simple and natural ways of mitigating the excess heat is to plant trees within the cities.”

He says the key is to make sure the trees you plant are well adapted to the region, so you don’t end up wasting water. He says that’ll be even more important as the climate continues to change.

‘Land Bank’ Reinvests in Inner City

One community is fighting its problems of abandoned lands and unpaid property taxes.
They’ve led to a decaying inner city and increased suburban sprawl. The new tool the
community is using is called a “land bank.” It uses a unique approach to try to fix up
properties that otherwise often would be left to deteriorate. The Great Lakes Radio
Consortium’s Chris McCarus reports:


(sound of work crews operating wood chipper)


Cleanup crews are sending downed branches through a wood chipper on a vacant lot.
They’re also removing tires, used diapers, car seats, sinks, old clothes and dead animal carcasses.
The workers are from the Genesee County Land Bank in Flint, Michigan. They’re trying to
make abandoned property useful again. Dan Kildee is the Genesee County Treasurer and the brains
behind the land bank. He thinks this new approach can recover unpaid property tax money and help
improve the Flint Metro area.


“The community gets to make a judgment on what we think we should do with this land. We get
to take a deep breath.”


Empty lots and rundown homes have been multiplying for a generation. That’s left the city of
Flint in a terrible economic state. But the land bank is beginning to change things.


Until just three years ago, Michigan was like most other states. No one had come up with
a solution. The state would auction off a city’s tax liens. Then conflict between the tax
lien buyer and the property owner could go on for up to seven years. In the meantime,
properties were left to neglect and often vandalized.


Under this new program, the treasurer’s office forecloses on a property and hands it over
to the land bank, which acts as the property manager. The land bank might then demolish
a house; it might throw out the owner and let a tenant buy it; or it might auction it off
to the highest bidder. A private investor can’t just buy a tax lien. He has to buy the
property along with it and take care of it.


The land bank is financed in two main ways: through fees on back taxes and through sales
of the few nicer homes or buildings the land bank acquires that bring in relatively big
profits. Treasurer Dan Kildee says it makes sense to take that revenue to fix up old
properties and sell them to people who deserve them.


“There is no system in the United States that pulls together these tools. Both the
ability to quickly assemble property into single ownership of the county, the tools
to manage it and the financing tools to develop that property.”


The land bank program hopes to change the perception of Flint. As thousands of abandoned
homes, stores and vacant lots become eyesores, people and their money go other places,
usually to build more sprawling suburbs. The perception that people are abandoning the
inner city then speeds up that abandonment. Many people who can afford to leave the city do.
And those who can’t afford to move are left behind.


According to data gathered by the research group Public Sector Consultants, Flint has the
state’s highest unemployment and crime rates and the lowest student test scores.


Art Potter is the land bank’s director. He thinks the downward spiral can be stopped.
When it is, those folks in the central city won’t have to suffer for still living there.


“Even though the City of Flint has lost 70,000 people in the last 30 years, the people who
are still here deserve to have a nice environment to live in. So our immediate goal is to
get control and to clean these properties now.”


Urban planning experts are watching the land bank approach. Michigan State
University’s Rex LaMore says Flint is typical of Midwestern cities whose manufacturing
base has shrunk. Private owners large and small have left unproductive property behind.
As the land bank steps in, LaMore says it’s likely to succeed and become an example that
other municipalities can follow.


“They can begin to maybe envision a city of the 21st century that will be different than
the cities of the 20th century or the 19th century that we see around the United States.
A city that reflects a more livable environment. So its an exciting opportunity. I think
we have the vision; the challenge is can we generate the resources? And the land bank model
does provide some opportunity to do that.”


But the land bank is meeting obstacles. For example, the new mayor of Flint who took over
in July canceled the city’s existing contracts. A conservative businessman, the mayor is
suspicious of the city’s past deals. They included one with the land bank to demolish 57
homes. This has slowed the land bank’s progress. Its officials are disappointed but they’re
still working with the mayor to get the money released.


(sound of kids chatting, then lawn mower starts up)


The weeds grow rampant in a neighborhood with broken up pavement and sometimes
no houses on an entire block. It’s open and in an odd way, peaceful. Like a
century-old farm. It’s as if the land has expelled the people who invaded with their bricks,
steel and concrete.


In the middle of all the vacant lots, Katherine Alymo sees possibilities.


“I’ve bought a number of properties in the auctions from the land bank and also got a side
lot acquisition from them for my house. My driveway wasn’t attached to my house when I
bought it. And it was this huge long process to try to get it from them. But they sold it
to me for a dollar. Finally.”


And since then, she’s hired people to fix the floors, paint walls and mow the lawns.
She’s also finding buyers for her properties who want to invest in the city as she has.
Together, they say they needed some help and the land bank is making that possible.

Governments Grapple With Regional Transport

Many large cities throughout the Midwest have been struggling with issues such as urban sprawl. Getting workers from one area to the jobs in another has become a transportation challenge. Building multi-lane highways only seems to encourage more sprawl, so many cities have worked with surrounding suburbs to build mass transit systems for the entire metropolitan region.

Many large cities throughout the Midwest have been struggling with
issues such as urban sprawl. Getting workers from one area to the jobs
in another has become a transportation challenge. Building multi-lane
highways only seems to encourage more sprawl. So many cities have worked
with surrounding suburbs to build mass transit systems for the entire
metropolitan region. For one major city, political leaders are just now
getting around to making that happen. And as the Great Lakes Radio
Consortium’s Jerome Vaughn reports… even now it’s not
going to be easy:


Detroit is the 10th largest city in the country…and it’s had more than
its share of struggles over issues such as chronic unemployment, poverty,
and pollution.


Finding solutions to those intractable problems has long been a goal of
government leaders in the area. But over the past three decades…they’ve lacked
one tool… used by most other metropolitan areas
around the country…that can make a difference. A regional transportation
system.


But that’s about to change.


Michigan Governor Jennifer Granholm has joined Detroit Mayor Kwame
Kilpatrick…and the heads of the three largest counties in Metro
Detroit…to announce the formation of the Detroit Area Regional
Transportation Authority…otherwise known as DARTA.


The new regional transportation authority is backed by local governments,
business interests ..and mass transit proponents. The government leaders have
signed an agreement to work towards the regional transportation
system. Detroit Mayor Kwame Kilpatrick says the new deal will benefit the
city AND suburbs.


“This is a real people thing today. It’s also an economic thing…and it’s
rare when these two things come together. This will drive the economic
engine of the state. To move people to jobs…leads to economic
independence.”


The agreement is the first step towards ending decades of debate over how
best to get workers from their homes to their jobs. With many Detroiters
living below the poverty level…owning a car is impossible. But that can
mean taking several buses over a span of three hours just to get to work
each day.


That type of commute is what DARTA proponents, like such as Attorney Richard
Bernstein hope to end. As a blind man…he’s unable to drive to get
where he needs to go. He says Detroit’s lack of coordinated mass
transportation pushed him to become a transit activist a couple of years
ago.


“As a disabled person who can’t drive…I struggle for my independence and I
struggle for my freedom. And DARTA is the only hope that someone like me
has in order to lead a quality of life here in Southeast Michigan.”


Bernstein says he’d like to have that extra measure of independence. But he
says…right now…it’s impossible for him to get around town on his
own…given the current state of mass transit in Metro Detroit.


“For me right now …it isn’t that regional transit is difficult to
use…it’s that it’s non existent …that is the issue. Ultimately, if I want
to get from my house …or my apartment to my office. There is no bus I can
take. There is no bus I can take from my office to court.”


But Bernstein’s passion for regional transportation isn’t uniformly shared.
The original measure creating DARTA was vetoed by former Governor John
Engler last year as one of his final acts in office. The state legislature
tried to resurrect the bill in January…but it has subsequently
stalled…pushing the new governor, Jennifer Granholm and Detroit Mayor Kwame
Kilpatrick and others to find alternate ways routes to create a working agreement.


The opponents say the regional transportation system is not fair. State
Representative Leon Drolet opposes DARTA because he says his more rural
constituents shouldn’t be taxed for a bus system they’ll never use. He wants a
provision that would let communities “opt-out” of the DARTA if they choose. The
Republican legislator says he also concerned because there’s no plan to pay for
DARTA yet. And he says no one’s convinced him that such a system is really
needed in Metro Detroit…home of the Big Three automakers..


“Macomb, Oakland suburban Wayne communities…those are built around the
car. Everywhere there’s a parking lot. Boston, Washington DC, New
York…those communities…mass transit is very viable in the inner areas
because it costs 30 bucks a day or 50 bucks a day to park your car. And
that’s what drives people to mass transit…the inconvenience of driving
your car.”


But automakers say they want the regional mass transit system. The
Southeastern Michigan Council of Government’s Transportation
Expert…Carmine Palombo…says many of the region’s businesses are having a
hard time getting workers from their homes to their jobs. And that includes
the Big Three automakers…who have come out in favor of DARTA.


“The auto company themselves employ people who need to have good transit in
order to get to their jobs…and so they’re feeling the pinch…just like
every other employer is who wants to get…make sure they get to the jobs
they have to offer in a stable environment. So the car companies aren’t the
problem.”


(sound up – bus)


While the Detroit Area Regional Transportation Authority agreement has been
signed….the work is just beginning for transit activists in
Metro-Detroit. The current agreement only provides for planning a
regional transportation system. There’s currently no money for
implementation of ANY plan.


And DARTA opponents such as Leon Drolet are still on the job, too. He’s
charging that the chairman of his county…had no authority to sign
the DARTA agreement…and is asking the State’s Attorney
General to investigate.
