Back in the days when Columbus had a population of 50,000 and had a huge demand for housing, city officials decided to spring up some high rises. The question was, where? Citizens protested very extremely when the city almost demolished 8 blocks of mansions between 4th street and 6th street, and Chestnut Street and Union Street. The mayor then realized he had to buy land, possibly from farmers, to build the high rises. He didn't want to keep expanding to the north and east for a suburban mess. The biggest concern for expanding near Downtown was that Columbus lies in a flood plain. These small quiet creeks that run through the area are nothing to underestimate. Mill Race Park floods an estimated every other year.
The city ended up raising funds to dig into the Flatrock River, making it deeper. Not a very common strategy, but it worked, and the city piled the dirt from that river south of town in a secret spot. Columbus loves to hide its share of the natural ugly things that all cities come with. Columbus plans to fill the river back up with the dirt after the city builds a reservoir north of town along the Flatrock, and another one along the Driftwood, and possibly one along Haw Creek, so that floods won't be so much of a concern any more. (Haw Creek only caused one major flood in noted history.) Flatrock Reservoir will be completed in an estimated 6 years, and Driftwood is expected to start in 3 years.
When the Flatrock River was completed, the city began to build Flatrock Parkway, which they had to demolish a very wealthy neighborhood in the process. The residents of that neighborhood were actually excited to move out and see what was to come, and for their generosity, all of the residents were rewarded with mansions in the Tipton Lakes area. Columbus is moving forward.
