What steps should be taken to prevent future flooding?

Living on the flat and having 4 to 5 feet of water in my basement during the August 24th flooding, I am very concerned on "What can be done?" or "What will be done?"

Most of us had water that came in through our floor drains. There has been a tractor pumping water from the sewer lines in my area to the main sewer line because the small pipe cannot keep up. This has been going on around the clock for four weeks. The city has to take a serious look at their infrastructure in regards to the sewers and what can and should be done. The tractor pumping water into the main line is only a band-aid.
 
Also, there was talk that when the flood gates were purchased, extra money could have been spent to allow turbines to reduce the water in the Dry Run Creek.  It was not in Decorah's budget, so the city opted out. Fast forward to three floods later, the city has to borrow or rent tractors to pump out the water. This saved us from two more floods after August 24th, but failed for the first flood since they were not there soon enough.
 
My question is, "How will all those condos affect flooding, since they're being built on the edge of Dry Run Creek?"  It looks like this will only add to the problem of flooding on the Flat. For now, it's homeowners that take it into their own hands. We have submersible sump pumps installed, new gutters installed, and caps put onto our water lines so it can not come in through our drains--all costing homeowners a great deal of money.
 
I praise the Water Department for working around the clock the past month.  Their efforts helped avoid more water damage.  But it is time the City looks into the problem and takes action. Does all the water have to flow into Dry Run Creek? Why not divert some of it elsewhere?  The City of Decorah should spend the money to have the appropriate people come in and look over the entire town and advise solutions to our flooding problems. And then they need to act on it. Our beautiful town will not continue to attract business and new people to move here if we are known as the "flood town" that does nothing.
