I'm kind of amazed at how much material they're moving. I'm not sure the mother nature couldn't eventually come to the same conclusion that the excavators are moving towards (with a few engineering exceptions) but they sure will do it a lot faster. Months instead of decades, I guess.

That must be a misstatement, there's no way they'd be anywhere close to doing all of that restoration and construction by the end of 2012. They hadn't even gotten to removing crap like the tires and shopping carts, until FLOW organized an event (pulling ~40 tires and ~15 carts, against contractor's instructions to stay out of the water).
If I were in charge I'd give the river a year to choose a channel, and in the meantime work on side issues like those sewer outfalls draining hot summer stormwater directly to the river - delay it in cooling ponds.
Keep in mind that with the dam, there was a pool beginning north of Lane, so there was almost no drop; that was all at the dam. Remove the dam, and the river has that much new height to drop; it becomes a younger stream as they say in geology. It will scour through all those sediments that were dropped in the slack water since the dam was built in the 1920s. That's happening now and it looks like some braided streambed in Alaska. I hope hope hope they don't manage that drop by putting in the ugly rip-rap riffles like at Wilson Bridge/270.

They should let it stay as a braided stream. Its better design than anything they can 'build'.

Nor does the 6 million or so price tag. It makes me wonder if the people planning and doing the work even know what they're doing.

I've been walking the "new" river bank a couple times a week, I almost made it from 5th ave all the way to Lane, the only impediments are around Drake Union. The amount of sediment being moved by the river is impressive. Down-cutting from the storm sewers opposite the stadium is about 4 feet at this point.
According to the propaganda billboards liberally scattered along the banks, the project is to be completed by fall of 2013.
It is pretty shocking to see the hillsides on the south west of the 5th ave bridge are being totally denuded of trees. The east side at least allows some sight lines.
Someone is making a lot of cash out of this project. All the soils being trucked in is expensive.

Yesterday I saw the first three snowy egrets of the year in there. Also saw a couple of blue herons, but I've seen them intermittently over the winter.
The fence and/or river have also kept the geese from being so aggressively territorial on the path.
It's really interesting to me to watch the changes in the river.Posted 1 month ago # -

Olentangy River Restoration A Year From Completion
May 20, 2013
by Sam Hendren
89.7 NPR News Reporter
Restoration of the Olentangy River on the Ohio State University campus continues. The work began last year when the 5th Avenue Dam was torn down. That left the Olentangy with a ragged appearance. The Olentangy’s bruises will take time to heal. The Olentangy is now so shallow that giant pieces of earth-moving equipment easily move up and down the middle of the river.

report that there is spray paint on the pillars holding up 315 where the new construction is by 5th ave?
I'm pretty sure they've seen it.

I know there was plenty there before- is it new, or just more easily seen now that they've removed so much vegetation?This is new. It's where you couldn't walk to before, but now you can because of the extended bank. I saw the same tag on the construction trailer parked there also.
