When we think about climate change, many of us think about it as a national, even international, problem. But a growing number of officials at the local level are beginning to see it as a local problem as well. Karen Kelly brings us the first
Of a two-part series on what cities are doing to
prepare for global warming:


Ron Sims has lived in Washington State his whole life, and he loves its unique environment: Puget Sound, the snow-capped mountains, and the salmon runs. But he’s worried about its future. He’s now the head of King County, Washington. It’s home to about 2 million residents, including the city of Seattle.


As county executive, he sees the scientific reports about his region.
They say the snow caps are melting, marine life is changing and the cedar trees are being replaced by other species. That’s what happening right now.


But what really convinced Sims he had to do something is when he called scientists at the nearby University of Washington’s School of Climate Impacts.


“And I asked them a simple question. I wanted to know what the climate in our area would be in 2050.”


The scientists’ report said King County could expect frequent torrential rains that would cause serious flooding, even swamping the buildings of some major employers. In terms of wildlife, the rains would wipe out the salmon’s spawning grounds. Yet, at other times of the year, they say they’ll be a drought as the snowcaps decline. Sims knew it was time to take action:


“Should we wait for our children to make this decision in 2045 or 2030? And since we now know that we have to make these decisions, based upon what the scientists are telling us, why aren’t we doing it now? Because generations in the future are going to have to make far more complex decisions and this shouldn’t be one of them they have to work from.


Sims isn’t the only city or county leader who’s taking climate change seriously.
The mayor of London, England starting charging people a fee for driving into his city during rush hour.


In New York, Mayor Michael Bloomberg made the same proposal to reduce emissions. He also wants to see a new rule that requires all New York City taxis to be hybrids within the next five years, and groups like the US Conference of Mayors are holding climate change summits to help local officials plan for the effects of global warming.


Jennifer Penney is with the Alliance for Resilient Cities, which recently brought local leaders to Toronto. She says a lot of officials are realizing that they’ll be on the front lines when serious weather events occur:


“Most of those things are in the jurisdiction of the local government. So protecting people from heat waves. Dealing with local floods. Dealing with wind storms or tornadoes that come through. Those are the kinds of things that local governments are on the ground, they have to deal with.”


And that’s why city and county officials across the nation are starting to make plans.


Back in Washington State, Ron Sims decided on two strategies to deal with this. One, reduce his county’s carbon emissions by 80 percent by 2050, mostly by getting cars off the road. That’s led the county to start buying up development rights on rural lands to prevent sprawl and the number of suburban commuters. They’ve also bought a fleet of hybrid buses.


And the second strategy? Start finding ways to adapt to the realities of climate change. King County has taken many steps. They range from a plan to strengthen their levies to prevent flooding, and the county is buying up forest land to act as a sponge for the runoff water. Sims says King County’s climate change plan has touched every department in the government:


“We decided to go backwards in time in all functions of this government… how we plan for growth, what do preserve, what will we face, what do we see the consequences of 2050 being, and are we prepared for that?”


A lot of people wonder if the public is ready for that, to sacrifice for it.
Ron Sims tells his colleagues in local government that the public is ready.
They saw the pictures of Hurricane Katrina. Many saw Al Gore’s documentary on climate change, and now they’re looking for elected officials, if not at the national level, then at the local level, to take the lead.

Faulty Flood Walls Spring Problems

Many people are drawn to live near rivers, lakes and other bodies of water. That means they have to take special care in case of floods, but flood walls and levees don’t always protect them. In one town, residents are asking why the wall separating their backyards from the neighboring river didn’t hold back the water.

Many people are drawn to live near rivers, lakes and other bodies of water. That means
they have to take special care in case of floods, but flood walls and levees don’t always
protect them. In one town, residents are asking why the wall separating their backyards
from the neighboring river didn’t hold back the water. The GLRC’s Julie Grant reports on
the safety of floodwalls and building in a floodplain:


Dale and Donna Smrdel bought a condominium along a river just a few months ago.
This summer they’ve been sitting in the backyard on a wall overlooking the river and
watching the sunset. But now, that concrete wall is broken and falling away from the
bank. It’s crumbled in some spots and held together only by twisted rebar.


“This is where the largest portion simply fell away because of the water. It was a torrent.
It was so strong it picked up a camper and flung it over this wall. Because the water was
so high above the wall, that it was like a toy. It just floated away like a toy.”


People on rafts rescued everyone from
second floor windows. Donna Smrdel says they thought this wall would protect them
from flooding:


“I don’t think there was a single person here that believed this was not going to keep us
safe. I think we all believed that even if the water did rise that it wouldn’t hurt the
retaining wall. None of us are engineers. We looked at it, it looked safe. We believed
we were safe. We had no idea, we just had no idea.”


This story is not uncommon. Last year, people in New Orleans expected a flood wall to
protect them from rising waters brought on by Hurricane Katrina. People along the
Mississippi River expected levees and flood walls to protect them from the Great Flood
of ’93. Many flood walls hold, but when they don’t, the people who thought they were
protected quickly find out they’re victims. In the case of the Smrdels, it turns out that
wall wasn’t even meant to protect them from high water.


Painesville City Manager Rita McMahon says the Smrdels live near the exit of the river,
where ice often jams in spring:


“Well, that wall was built by the private property owner as actually a flood protection
from ice dams. It wasn’t intended to protect the property from this type of a flood. This
was a volume flood that came from the south to the north. It was just a wall of water, so
to speak.”


The Smrdel’s condo community was built in the 100-year floodplain 30 years ago. Back
then, there weren’t regulations on building in a flood-prone area. Today, new buildings
have to be elevated.


That’s better protection then a wall, but flood walls and levee protection give people a
sense of security. Often they don’t think about that protection failing them, and the
consequences of what that failure will mean to their homes and families. Engineers say it
is possible to live safely by the water, but homeowners have to do their own investigating
to find out the safety of housing elevations and flood walls. We spoke with Carm
Marranka, a structural engineer with the US Army Corps of Engineers:


Julie: “When you look at Katrina, when you look at the Mississippi floods in ’93, and when we
look up here, do you think that sometimes flood walls, even those built by the Army Corps,
provide a false sense of security?”


Marranka: “I don’t know if it’s a false sense of security. I think
with the design and assumptions that I’m familiar with the factors of safety, those
structures are built at. And good maintenance, I think that’s a big issue. They have to be
maintained. They cannot be allowed to fall into disrepair.”


When the Army Corps builds a flood wall, Marranka says it’s usually up to the local
community to maintain it, but the local governments often don’t have enough money to
pay for that maintenance. Donna Smrdel doesn’t trust any of it anymore:


“I mean, even if they bulldozed it, what kind of retaining wall will they build next? If
this didn’t work, and we all believed it would work, what do you build next?”


All those other people flooded out of their homes will also have to decide whether they
trust flood prevention technology, and if living by the beautiful scenery is worth the
threat of floods.

Price of Natural Gas Falling

The price of natural gas spiked last fall after Hurricane Katrina knocked out production in the Gulf. But prices have come down substantially since then, and the amount of natural gas in storage is growing. The GLRC’s Erin Toner explains what that could mean for consumers:

The price of natural gas spiked last fall after Hurricane Katrina knocked out production
in the Gulf. But prices have come down substantially since then, and the amount of
natural gas in storage is growing. The GLRC’s Erin Toner explains what that could mean
for consumers.


During the summer, natural gas is put into storage for the coming winter.
Because last winter was relatively warm, the amount of gas in storage has grown
to its highest level since the government began collecting data in 1994.


Jim Kendell is director of the Natural Gas Division at the U.S. Energy Information Administration.
He says the buildup of gas in storage will likely mean lower energy bills this winter:


“Unless we have a really hot summer this summer, or unless we have some more hurricanes.”


Kendell says barring those extremes, consumer prices for natural gas in the winter
shouldn’t rise too much from where they are now, meaning prices could be down 20 percent
over last year.
