Building a wall against the flood

If you've been following Science Buzz (of course you have!) you know that St. Paul is gearing up for a flood!

It's still unclear as to how high the water will rise, but given all the snow we got this winter, the Science Museum is preparing for the worst. The worst is unlikely, but even not-quite-the-worst would be pretty bad, so the museum is building some defenses against the water.

Our Science House is being surrounded by a wall of thick, solid concrete blocks, like a fort. And we're building a wall of Jersey barriers packed with dirt through the Big Back Yard to protect our first floor, should the water get that high. The museum's first floor, by the way, is not where you enter. The first floor is way below that, and it's where we build exhibits and keep all of the machinery that maintains the climate in the building, so it's important that it doesn't get too wet down there.

Here's a slide show of the pictures I took of the construction this afternoon. For descriptions of what's happening in each, click on the photo (or go right to the Flickr photoset).

Now this is smart thinking. When we take the steps to be proactive we can prevent so many things that really do not need to happen. It only makes sense that all of snow they have gotten is going to turn to water. It is best to be prepared.
