To prevent flooding - the city of Des Moines Iowa built a "Retention Basin". It's 4 acres wide and cost about $5 million to build. What were the consultants & engineers thinking when they constructed this basin? What might have been on their mind? No one knew - until we got a look at it from above. Pretty racy - especially for Iowa.
Now here's a look at the proposed new Des Moines lakefront. There is no pricetag yet, but it's expected to be high. Really high.
