       | I don't know if this was during the same time period or not, but
       | in some parts of the city (mostly residential or smaller
       | commercial areas) they didn't bother raising the buildings, they
       | just built the streets up higher and added flying walkways from
       | the new sidewalk height to the new front entrances on the second
       | story of the houses. Many of them had stairs that went down to
       | the old ground level and I think in most of them they had been
       | converted to separate apartments.
       | 
       | My dad's small commercial building in Pilsen looked normal, but
       | if you peeked into the holes in the sidewalk out front you could
       | see a vaulted space underneath where the old sidewalk used to be,
       | which was kind of unnerving when you realized the sidewalk was
       | crumbling. You could even access it from the basement of his
       | building (which I suppose used to be the ground level?), but he
       | never let me go down there as a kid.
       | 
       | I also know of one or two old homes from around this time period
       | in the neighborhood I grew up in (which wasn't part of Chicago at
       | this time) that were later moved off what became the main avenue
       | through the area to new locations about a block away. I think
       | that happened much later though.

       | reservoirs? Yep. Let's get 'er done."
       | 
       | A lot of places I've lived, things like that wouldn't fly. I was
       | equally amazed at Phoenix with their, what I can only call a
       | "strategic water reserve".
       | 
       | A lot of thought and money goes into stuff like that.
       | 
       | I get the strong sense that in most American cities if you would
       | have told the population that we all need to undertake a massive
       | public work, _(Oh, and pay for it by the way)_ , they would yank
       | you from office and tell you to go F yourself.

         | the original downtown of Seattle got moved up 1 floor: they
         | didn't raise the buildings, they raised the street, the old 2nd
         | floors became first floors.* You can still visit the
         | underground Seattle in some places.

         | 
         | * carefully worded to also work on European floor number
         | systems.

         | They massively re-landscaped most of downtown seattle, in one
         | phase by using hoses to blast hills down and extend the
         | waterfront. In another phase they built the streets up like 12'
         | or more. I think stuff like this happened in many places.
         | 
         | Really it still does. I'll trigger many bostonians by invoking
         | the dig. Seattle has bored some massive tunnels recently and
         | re-scaped its waterfront

           | I think there is a misunderstanding of the engineering
           | challenges in some of these projects.
           | 
           | The Big Dig was less than 10 miles, never deeper than roughly
           | 100 ft. TARP is over 100 miles always deeper than 100 ft. And
           | because of intended use, it all has to be dug through solid
           | limestone bedrock. The engineering challenges are non trivial
           | in both, but one is on a massive scale that the other is just
           | not.
           | 
           | Speaking to the Seattle example, the reason for building the
           | streets higher is that, in Seattle, people would have
           | revolted if they had decree'd "All shalt raise thine
           | buildings 12 to 24 feet as did the multitudes in Chicago."
           | That's what I mean. Seattle is the example that proves the
           | rule. No one had the political capital to force a Chicago
           | style raise on Seattle.
           | 
           | That said, between you and me, as an engineer, I would have
           | done things the Seattle way and left the buildings at ground
           | level. Raised the streets and then turn the formerly ground
           | level floors into basements. It's not the end of the world if
           | basements flood from time to time. And some drainage might
           | even help with that. Chicago, on the other hand, wanted the
           | "complete" solution. They were done with dealing with floods.
           | Even in basements, they were intent on eradicating flooding.
           | Which is a laudable goal, and Chicago has been much better
           | off because of it. But the risk and the cost is just a whole
           | lot higher than I would have felt comfortable with given the
           | tech available to me at the time.

       | The whole concept is bonkers! By this i mean that i can not

       | something so big and audacious nowadays. Also, my favorite note
       | in the wikipedia entry (besides the whole article being
       | awesome!), is this one: "Many of the city's old wooden buildings
       | were considered not worth raising, so instead the owners of these
       | wooden buildings had them either demolished or else placed on
       | rollers and moved to the outskirts of Chicago. Business
       | activities in such buildings continued, as they were being
       | moved." Just crazy!

       | Ah man - this is one of the cooler things i've ever heard of. I
       | first heard of it in PBS doco "Chicago: City of the Century".
       | That documentary - is one of the finest chronicles of modern
       | society i've ever seen. The insights into psychology, civil
       | engineering, and history are second to none. Most profound to me
       | were the "design" of suburbs with the trappings we dont think
       | very much of these days - libraries, pools, shopping centres and
       | so on - were created to push "ideal lives" which were basically
       | the dangled carrots of real estate empires. Brilliant stuff.
