Bugs are getting confused by the
reflections from manmade structures.
Rebecca Williams reports on a new study:

If you’ve ever noticed swarms of insects hovering over your car, there’s a
good chance they’re mistaking it for water.


Smooth, dark surfaces like cars and asphalt reflect polarized light. That’s
what bugs see – and that tricks insects such as dragonflies.


Bruce Robertson is an author of the study in the journal Frontiers in Ecology
and the Environment.


“Asphalt actually reflects polarized light more strongly than water and so it
looks more like water than water! And so these organisms are thinking
they’re finding a place to breed and hunt and lay eggs and mate when in fact
they’re finding a place that’s very dangerous.”


Robertson says these bugs swarm over buildings and roads in huge numbers,
and can die of exhaustion.


But he says it might be possible to stop tricking the bugs. Things like
adding white curtains to dark windows or adding a little bit of gravel to
asphalt to make the surfaces reflect less polarized light.

The Logic of Parking Rate Hikes

Nobody likes to pay more than
they need to for parking, but a lot
of cities are bumping up the price
lately. Chicago’s going with one
of the biggest hikes. In most
neighborhoods prices are doubling,
and they’ll jump again and again
for years to come. Shawn Allee wondered what might happen to
businesses when parking gets pricier:

I’m in a neighborhood miles from Chicago’s glitzy downtown, but there’re still
plenty of shops, restaurants and furniture stores to attract shoppers up here.

One problem the neighborhood has is parking.

Until recently, it only cost 25 cents per hour to park here. As you can guess, the very
cheap price for parking has meant very few parking spots available for people who
are driving through.

Now, the neighborhood’s going through a change. It’s bumping up to 75 cents per
hour, and in a few years it will cost 2 dollars per hour.

So, I’m here to see what businesses think will happen to their bottom line once this
price increase for parking comes through.

I’m gonna start at this grocery store.

It’s called Pars Grocery – the sign here says it serves up Mediterranean food, teas,
and gifts.

The owner’s Cyrus Haghighi.

Haghighi: “So of course nobody would come and it would be too expensive for them
to spend too much money for the parking, and I don’t know why they’re doing this
– it makes everybody worried.

Well, that’s one owner who thinks the parking price increase is going to scare
shoppers away.

But I went around the neighborhood to get some other opinions, and I’m now at
another store – the Andersonville Galleria.

I have a clerk here.

His name is Rafe Pipin

Rafe what do you think of the parking price increase?

Pipin: “With the parking meter rates being a quarter an hour now, what happens a
lot of times is that store employees or managers take up the parking on the street
and stay there all day, whereas this may might provoke them to look for parking
further away. So they wouldn’t have to feed higher meter rates all day and open up
space for people visiting the neighborhood to do some shopping.”

Okay. We have two opinions.

One, higher prices will scare people away.

And, another that higher prices might free up space for more paying customers.

Who’s got it right?

Well, I put this to a kind of parking guru.

His name’s Donald Shoup, and he teaches at UCLA.

I’ve told Dr. Shoup about how tight parking is in this neighborhood and where prices are
headed.

“The higher prices that drive away some people will attract other people who are
willing to pay for the curb parking if they can easily find a space. Well, who do you
think will spend more in a store or leave a bigger tip in a restaurant? Somebody
who will come only park free or someone who’s willing to pay the market price for
parking if they can easily find a vacant space?”

Dr. Shoup says cities often make parking too cheap.

He says this discourages public transit.

Plus, it wastes gas because meters fill up fast, and shoppers keep driving around to find
the few empty ones.

Shoup says politicians just don’t want to increase fees.

In Chicago’s case, the city privatized parking meters, so the city made one tough decision
that will last 75 years.

Shoup says there’s a better way – set aside some of the parking money and spend it in
neighborhoods that generate it. Donald Shoup says some people still won’t like parking price increases.

But he says there’s plenty of fuss at first, but then people eventually chuck over the
additional money and forget the increase ever happened.

Commuter Parking on the Rails

  • The South Shore Commuter Rail Line runs between South Bend, Indiana and Chicago. The line's reaching its 100th birthday, and as it does, its ridership is near a 50-year high. It serves many sizable towns, such as Hammond and Gary, but commuters from smaller towns, suburbs and even rural areas drive to, and sometimes cram, the rail lines' stations. (Photo by Shawn Allee)

More and more people who live in
suburbs have been climbing onto commuter
trains over the past few years. They’ve
got every reason to: they’re fighting high
gas prices, traffic congestion, or even big
road construction projects. But oddly enough,
cars remain a problem even when people choose
commuter rail. Shawn Allee found
that out first hand when he checked out one

More and more people who live in
suburbs have been climbing onto commuter
trains over the past few years. They’ve
got every reason to: they’re fighting high
gas prices, traffic congestion, or even big
road construction projects. But oddly enough,
cars remain a problem even when people choose
commuter rail. Shawn Allee found
that out first hand when he checked out one
system:

I’ve just got into a parking lot in a commuter rail station in Northwest
Indiana. This rail line runs from towns like Gary and Hammond Indiana to
Chicago, where there are a lot of jobs.

Anyway, officials with the rail line tell me parking happens to be one of the
biggest complaints. I’m here to check it out, and I gotta tell you I’ve been
driving past hundreds of parked cars, and I haven’t been able to see an
open spot yet.

Okay, finally found one.

(sound of door slamming)

Shawn Allee: “Getting a parking spot in this station took a lot longer than I
expected. This commuter here, Celia Ramirez, says she has the same
problem. What’s it usually like?”

Celia Ramirez: “It’s a dread, because I don’t know where to park.
Sometimes I park where I’m not supposed to park, on the residential
streets.”

Allee: “And then you’re taking your chances.”

Ramirez: “Yes, of getting a ticket.”

Allee: “In fact there are signs all around us right now that pretty much
warn you not to do that.”

Ramirez: “And I break that rule.”

Well, you can guess spillover parking around the rail station in Hammond ticks off
the neighbors.

To make matters worse, a lot of the commuters, they don’t even in live in Hammond.
They’re from towns or suburbs even farther out.

In fact, the local government and The Northern Indiana Commuter Transportation
District don’t always agree on how to solve the problem.

John Parsons is the rail line’s marketing director.

John Parsons: “We have over 700 spaces in Hammond. Unfortunately, we
need more. But the residents in the area are reluctant to expand parking.”

Shawn Allee: “How difficult is it to convince towns to do that, especially if
they feel that they’re creating parking for people outside of their area?”

Parsons: “It’s a difficult problem. For one thing, we’re a tax-exempt
organization and what we’re doing is acquiring residential property that
currently pays taxes and that property’s no longer on the tax rolls.”

Now, this particular rail line had a growth spurt a few years ago. It’s lightened up,
but parking’s still an issue.

So, just imagine pressure other rail lines have, especially ones that saw double-digit
growth over the past year.

The situation’s familiar to transportation experts.

Joe Schwieterman teaches at DePaul University.

He says, when it comes to parking, suburban commuter rail is often behind the ball.

“The ridership is surging on our transit system, and parking spots, you
know, it’s a five a five-year process. If we start now, we have new spots you
know, in 2013. Clearly that’s not fast enough to tap into that new market.”

So, is there a way out of the parking – commuter rail conundrum?

Schwieterman says one idea is to add bus service that branches out from stations.

But not all towns can afford it, or they don’t have enough riders to justify buses.

So, Schwieterman says some commuter rail lines are stuck.

They advertise that they’re a cheap, convenient alternative to driving. And when gas
prices rise, people take that advice.

“It’s a bad idea to encourage floods of people to take public transit if you’re
not ready to accommodate them. You lose them for life, frankly, if it’s a bad
experience.”

Still, Schwieterman says you can look at the parking problem two ways.

Sure, you can shake your head because suburban stations’ parking lots fill up.

But, at least for now, those drivers aren’t clogging roads and spewing even more
pollution on their way to work.

The High Costs of Empty Parking Lots (Part Ii)

  • A new book says that much of the space covered by parking lots is only designed for use for the holiday rush, and is unused for the rest of the year. (Photo by Lars Sundström)

A growing number of city planners say we’re building more parking than we really need. They say the fact that nearly all parking is free, makes the situation worse. Their ideas are turning nearly fifty years of urban planning on its head. The Great Lakes Radio Consortium’s Shawn Allee has this second report in a two-part series:

Transcript

A growing number of city planners say we’re building more parking than we really need. They say the fact that nearly all parking is free, makes the situation worse. Their ideas are turning nearly fifty years of urban planning on its head. The Great Lakes Radio Consortium’s Shawn Allee has this report:


If you had to pay for a parking space, would you think twice before making a frivolous trip, say, to a convenience store for a candy bar?


City planning researcher Donald Shoup bets you would stay home if you had to pay, or maybe you’d walk instead. That’s a point he makes in his recent book, The High Cost of Free Parking. In it, he tries to show that free parking entices us to waste gas. He says paved lots also compete for better uses of land, like parks or housing. Shoup says the problem’s very real – but to see it, you need to step out of your automobile.


“Any view of suburbia from the air will show you a lot of parking lots and a lot of these parking lots will have empty parking spaces.”


I decided to take a look at what’s Shoup’s talking about in Lincolnwood Illinois, a Chicago suburb. I cheated by skipping the air fare, though. Some new Internet sites can provide satellite photos of your area. I joined two of Lincolnwood’s city planners, Tim Clarke and John Lebeque, in their office to get a birds-eye view of their home turf.


Clarke: “The plus is closer.”


Allee: “Right, and go ahead and see if you can find… There it is. Lincolnwood.”


Clarke: “Wow.”


Lebeque: “Whoa.”


Allee: “So find a retail strip.”


Turns out, Donald Shoup was right. Within a minute, we find a popular grocery store, with a huge parking lot. Tim Clarke recognizes it.


“It’s probably one-third filled. I’m not sure when this aerial was taken. I’ve never seen the parking lot full.”


So why should a busy store’s parking lot be two-thirds empty most of the time? Shoup says it’s the cities’ fault. Cities make the rules. They say how many spaces each new business, house, and apartment building must provide.


By his estimation, city government does a poor job at guessing how much parking we really need. Shoup says governments force businesses to provide enough spaces to meet peak demand, such as the day after Thanksgiving, the busiest shopping day of the year.


“Everyone understands the advice, don’t build your church for Easter Sunday, but we build our parking for the week before Christmas.”


In other words, cities tell stores to build parking for the year’s busiest two weeks, even if most of the spaces are empty the rest of the time. He says, without city pressure, a lot of businesses would create smaller lots or they’d sell off parking space they don’t need.


Tim Clarke, the Lincolnwood planner, says suburbs do err on the side of too much parking, but they’re often planning for future growth. He gives an example of a small Lincolnwood dental practice that had 7 examination rooms, but only used three of them. The dentist wanted to build fewer parking spaces than the village required, because it was small and family-run.


“But one could imagine that that family at some time in life would sell that business and someone would come in and want to use all 6 or 7 examining rooms at one time.”


So city planners have to look at the long term use of a building.


Many of Lincolnwood’s largest retailers actually build more than they need to. Bob Johnson runs a Lowe’s Home Improvement store built in late 2003. He says stores like his don’t gamble with having too few spaces.


“I think customers are going to shop, again, where they feel most comfortable and what’s convenient for them. The key word there being convenience. If they’re inconvenienced, they might drive another couple blocks down the road.”


Shoup says that’s a calculation that businesses have to make. He says market forces can help decide how many spaces should be built, but government should not force retailers to have too many spaces. Nor should it force them to offer only free parking.


In fact, Professor Shoup says cities, especially suburban cities, could use land more efficiently if businesses controlled demand for parking like they control everything else: by setting the right price.


“I’m just saying that cities should not force anyone to provide more parking than drivers are willing to pay for.”


Killing our appetite for cheap, abundant parking could be difficult, but Shoup says pressure’s building for change. He says, as suburbs grow, space gets tight. And that raises prices for all land uses.


“I think most people now are focused on the high cost of housing. I think we’ve got our priorities wrong if housing is expensive and the parking is free.”


In his battle against too much parking, Shoup says the most effective weapon might be a little comparison shopping. Free parking might not seem so cheap once it’s compared to the cost of other needs.

The Debate Over Mobile Home Parks

  • Because mobile homes can be transported they're not taxed the way permanent homes are. They're taxed like vehicles (when they're bought and sold). Mobile home owners pay a small tax for the small plot of land they sit on. (Photo by Chris McCarus)

People who live in mobile homes might be seeing their property taxes going up. Some government officials say it’s an attempt to tax for the services used and to discourage mobile home parks from sprawling across former farm fields. But others wonder if higher taxes aren’t a form of discrimination against this kind of affordable housing. The Great Lakes Radio Consortium’s Chris McCarus reports:

People who live in mobile homes might be seeing their property taxes going up. Some government officials say it’s an attempt to tax for the services used and to discourage mobile home parks from sprawling across former farm fields. But others wonder if higher taxes aren’t a form of discrimination against this kind of affordable housing. The Great Lakes Radio Consortium’s Chris McCarus reports:


(sound of expressway traffic)


The Capital Crossings mobile home park sits on rolling farmland near an Interstate highway. The residents of the 15 homes have moved here either to retire or to make the 30 minute daily commute to nearby Lansing, Michigan. And more mobile homes are being pulled in.


(sound of construction)


Workers are building porches and attaching the skirting between the ground and the house. It’s supposed to show permanence, like a foundation. But mobile homes are not permanent. And mobile homes are not taxed the same way as other houses. They’re taxed like vehicles. Taxed when they’re purchased. Taxed when they’re sold. Still there are no property taxes on the homes. Only on the tiny lots on which they sit.


Some government officials say the $3 a month that these park residents have been paying for property taxes don’t cover the costs of police and fire protection or other government services. They want a tax hike to give local governments more money. Dave Morris is a farmer and the local township supervisor.


“We all have to pay our fair share for services such as sheriff, ambulance, fire department as well as schools. Schools is a big issue of course. And they aren’t paying their share. That’s all.”


But advocates for affordable housing say hiking taxes on mobile home residents is more likely just an attempt to discourage that kind of housing. They say zoning mobile homes out of existence has been tried, but taxing them out is a new idea. Higher taxes will likely lead to mobile home parks closing.”


John McIlwain is with the Urban Land Institute. He says as mobile home parks become more expensive to operate, their owners will sell off to subdivision or big box store developers.


“The numbers are going to be so attractive that the people who own mobile home parks are going to be much more interested in selling the land to a housing developer than in continuing to run the mobile home park. So in time the parks are probably going to disappear on their own anyway and trying to raise the taxes on them specifically is simply going to make that day come earlier.”


In Michigan there is a proposal to raise the taxes on mobile home sites four times higher. State Senator Valde Garcia says the $3 a month that mobile home park owners pay for each home site is not nearly enough.


“What we are trying to do is really change the tax structure so it’s fair to everyone. The system hasn’t changed in 45 years. It’s time we do so but we need to do it in a gradual manner.”


Senator Garcia’s colleagues in the state house have voted to raise the tax to $12 a month. He’d like to raise it to at least $40 a month. The mobile home park industry has hired a public relations firm to produce a video criticizing the tax increase.


“Site built homes pay sales tax only the materials used in their homes and don’t pay tax on resale. Manufactured home owners pay sales tax on materials, labor, transportation profit of a home and they pay sales tax every time a home is resold. ”


The two sides don’t agree on the math. Tim Dewitt of the Michigan Manufactured Housing Association says $3 a month sounds low because it doesn’t show hidden costs. The biggest cost comes when park owners have to pay the higher commercial property tax instead of the lower homestead tax. Dewitt says the park owners then pass the tax to the home owners whose average family income is only about $28,000 a year.


“That’s our worst fear. It could put people who could least afford any type of tax increase into a tough position.”


15 million people live in mobile home parks around the country. And different local governments have tried to find ways to increase taxes on mobile home parks. But Michigan is one of the first states to propose hiking taxes this much. State Senator Garcia says he is not trying to hurt the mobile home industry or make life harder for mobile home park residents. He dismisses the idea that he’s being pressured by wealthier constituents who don’t like to see the mobile home parks being developed.


John McIlwain of the Urban Land Institute says a bias against mobile home parks is part of the mentality that leads to sprawl. When people from the city and the suburbs move a little further into rural areas they want the look and feel of suburbia.


“The mobile home parks are no longer things that they want to see. And so they find ways to discourage those mobile home parks. The ones that are there try to see if they can be purchased, turned into stick built housing or otherwise discourage them and encourage them to move on elsewhere.”


But often the people who move in also want the shopping centers, restaurants and conveniences they once had instead of the mobile home parks.
