In Davenport, if the Mississippi rises above major flood stage -- floodwater will start to surround Modern Woodmen Park.
Leclaire Park will be underwater, as well as sections of River Drive.
That's why public works crews have spent the entire day focusing on flood protection efforts.
Initially, the river was supposed to crest at 15 - 16 ft. Now, the predictions have been raised to almost 19 feet.
This changes flood fighting efforts significantly.
More infrastructure is impacting and public works crews have to work fast as the water continues to rise.
"The challenge is to think through the unknowns and get that right the first time," said Mike Clarke, Davenport Public Works Director.
"Set our levels of protection for the next 48 hours so we're ready on Friday when the crest begins to arrive."
While the crest is predicted at roughly 19 ft., crews are protecting infrastructure for up to 22 ft. of water.
Credit Island is now closed to the public and part of River Drive is expected to be shut down on Thursday.
