King G -Past is Prologue. We nearly lost the Arcade through a precipitous action. I don't want to lose the river scape the same way. These were the approximate comments I gave at Monday night's Board Meeting, which was not televised live because of the change of venue. So I offer them here:
April 4, 2011
Good Evening Ladies and Gentlemen:
Tonight I want to inform those who are here and those at home about some aspects of the dam removal program of which you may be unaware.
I’ve scrutinized the revised 50% draft of the Hofmann Dam removal all 304 pages plus the drawings and ancillary documents, and made some calls and paid some visits because, when you look closely and ask questions and write e-mails and visit offices you learn something, and I would like to pass on what I’ve learned to the Board and to the residents who are going to be affected by this project. Not just during the three or more year construction period, but forever. Because that is what this will do - change Riverside FOREVER. What we are going to lose here we will never get back.
I’ve been working on a script, and watching some old movies, so I thought I’d call this report to the residents The Good, The Bad and the Ugly. Getting right to it...
THE GOOD is that the Army Corps now says if they go forward they will do the actual dam removal portion of this job from where I advocated back in September, from the south bank at the 39th Street Forest Preserve. That should keep hundreds of trucks and lots of heavy macinery off our streets. Lots, but not all. And of course, when I went to visit the FP District headquarters two weeks ago and talked with the man in charge of granting easements he told me he hadn’t seen or spoken with anyone from the Corps or IDNR about this project for more than six months - but perhaps they have the intention to do so.
One of their intentions is to remove whatever is left of the previous “legacy dam or dams as they call them that are up behind the present dam. This is important to remember - they still can’t define what is out there, so it means they haven’t been there to survey what is left. And I’ll tell you why that is important next.
THE BAD, as usual, is a little more complicated than the good. I call it The Case of the Missing Sediment. And that’s quite a feat to make that amount of this dreck disappear. You may remember that we were previously told that there were 21,000 cubic yards of contaminated sediment above the dam, and that the closest 3,000 cu. ids. or 15% of it would be excavated, dumped into denaturing containers, drained and hauled away., so that it wouldn’t wash out and lodge on the banks downstream.
Now 3,000yards is at least 300 heavy truckloads that previously were supposed to be loaded and dewatered above the dam n Fairbank Road, and sowhile I was happy to keep that work out of Riverside i Was curious as to how that would be done working from below, in the wet, so to speak. The contract calls for removing sediment before beginning the dam removal, but seing no reference to how that would be accomplished, I emailed one of the Corps engineers working on this project and got this surprising reply on 3/31, six weeks after the draft calling for the removal of 3,000 cubic yards of sediment was published online.
“Recent surveys showed virtually no sediment accumulation upstream of the dam, and that no sediment removal will be needed.”
Now wait a minute - one of the big reasons for removing this dam was because of all the contaminated stuff that had accumulated - so much that they were calling the river “dead” if I remember correctly. First, when I questioned these guys about why they were doing this crazy project it was because the fish wouldn’t like the contaminated PCB laden sediment, and now, suddenly, it’s not there. This latest draft containes pages of chemical analysis charts that says this poison is out there, and calls for removal of 3,000 cubic yards of it and the stabilization of the rest, and now suddenly it’s not there. And when were these proposed surveys done? The contract still calls for the chosen contractor to conduct a survey in ten foot squares for the first hunred feet above the dam to determine the amount, depth and location of the sediment there, and now, before that is done, they claim there is no sediment. Does anybody else whiff the faint aroma of performing seals here? Remember when I said going for the Little Dam first, and saying it was in Lyons was “bait and switch.” Well here we are again, with the same MO. And there’s more.
Back at the meeting in November I asked Mr. Juhl if he enjoyed his boat trip on the river to go out and see what remained of the old dam and he said they didn’t go out to survey the “legacy dam” because it was too dangerous to go near the present dam. In fact he admitted that none of the engineers had ever done any work closer than 200 feet of the dam. That was in November. No one has been out on the river since. So how is the sediment removal not necessary?
And even though I’ve been told that there is no sediment above the river I found this note on a drawing: “All newly exposed bank shall be planted and protected within one day of becoming exposed.” Now why do you suppose they specify that? Could it be that the contaminated sediment that is all over up there is as fine as talc, and when it dries it will blow everywhere? And what's going to happen up and down river where they aren’t doing any work andthis condition occurs?
Don’t forget - they still want three year easements for the parkland along Fairbank Road so they can create fenced areas for equipment and supplies and entry /exit to the river for what they call “Bank Access, Staging and Storage.” Inother words, dealing with the messy part of the job. So there will still be hundreds of truck and lots of mavinery and cars coming and going and tracking this goop all over town.
Folks, as it stands, they are going to proceed with whatever they think up and we won’t have anything to say about it unless we use the one tool we have left to halt this thing - the granting of the easement for the Little Dam. If we don’t act to stop this now we are in line for anything these guys want to do, any old job, anyway they see fit, because they will draw their contract between the Corps and the contractor, and we get whatever they want to do. We shouldn’t be letting people from somewhere else come into historic Riverside and do this kind of shuffle - remember we went for that once before with the Arcade and came close to losing it. Both dams are wholly within the Rivrside Historic Architectural District and integral features of that district as registered, and saying the Little Dam is in Lyons is bogus - it doesn’t touch Lyons anywhere. If they want to work at the Little Dam let them get there from the Forest Preserve - if they can do it for Hofmann they can do it for Fairbank Dam.
Now for THE UGLY - the REALLY UGLY is the outcome, the part that future generations will have to live with, with only old photos to show them what we once had here, the reason why there is a Riverside.
First, now the “notching” of the Hofmann Dam, which was previously 150 feet or 60%, is now extending an additional 37.5 feet on each side at half height, in effect altering 90% of the dam’s total length. The drawings they published show that these wings will still be there to catch trees and such at high water, but at low water or even at their “normal flow” the river will not even fill the center gap nor the central span of the Barrypoint Bridge.
Their “normal flow” drawings now show large areas - they say it is about 5.5 acres - that will be exposed immediately above the dam when the water level drops - perhaps 8-9 feet. This will create “new land” which is to be seeded and planted with native wetland plants - mostly grasses - because remember, these “new land” areas will still flood over when the river rises above 6-7 ft. on the gage. Today for instance, with the river at around 4 ft., they will be partially inundated. And since it won’t be all level, it will trap inaccessible pools of water that will provide for mosquito breeding.
For those who haven’t seen the latest drawings, let me describe what the river will look like if this project goes forward. Where the broad water is currently lagoon like just above the dam it is about 400 ft wide. When the dam is removed it will be receding to less than 50 ft. wide in some places. Their own drawings show it will be less than the width of this room. And since it will be - by their estimates - 3-7 feet lower, in the areas where these grasses don’t wash out you will hardly see it from Fairbank Road.
Upstream of about 280 Fairbank and all around to 31st Street, where they are not doing any work, you will have just what I forecast back in September, 30-40 ft. or wider debris-laden exposed mud banks on each side of the river - and that’s at what they call “Normal Flow.” We often have long periods, as we did this year, that are lower flow levels than that. The residents up along Maplewood can say “Bye-bye” to the river as we all know it.
And this project will extend right into the CBD, right outside here in the center of town, because the Swan Pond regrading will require the movement , by their own estimate, of almost 15,000 cubic yards of material - stone and topsoil and sod and seed and fertilizer and all the rest - coming right down here next to the library. That’s another 1500 big heavy truckloads rolling in and out along with all the rest of the equipment, workers cars, etc. And after all this the Swan Pond will still flood.
The way this program lays out is that first - soon - they will come in and tear up the park around the Little Dam and bang that out. Then they’ll go away. Next year will be the Big Dam, and all that mess, and no doubt the sediment that suddenly isn’t there spreading all along the banks and river bed down stream. Then there will be the replanting and, when that washes out, the replanting, etc., ad infinitem. Further north along the river, no planting, nothing except more responsibility for the Village. But don’t call them to come and fix anything - they won’t have any more money.
This project needs to be totally reevaluated. It is clear that it is no longer going to offer benefits that outweigh the risk and the yars of mess. Once the work begins on the Little Dam we will be locked into this whole, sorry project and totally in the dark as to the outcome. These people have never removed a dam in Illinois and have no outcome data to support their claims. We are letting them experiment iwth historic Riverside. Only by saying STOP!, now, can we avoid what will be a sorry outcome for the Village after enduring years of mess and chaos.
The Little Dam is useful as it is. It stops the invasive Zebra Mussels from going further upstream. It was built at an angle to direct water toward the Swan Pond in time of flood and thus help keep the inundation for our neighbors in Riverside Lawn to a minimum. It’s impoundment water slows the velocity of the river as it careens down toward Library Hill at times of flood. It is a place that is peaceful and where the sound of the water cascading, the heron fishing, the ducks quacking offers respite and masks the noise of the traffic from Ogden Avenue. It is a precious resource for people and animals of all kinds, this tiny, precious island of tranquility, just nine miles from the Sears Tower. Why do you want to destroy it?
There are so many questions yet unanswered. The project has changed so much, and so much potential harm and liability lies within it, that the village has ample grounds to rescind the easement that was precipitously granted back in September. At that time the excuse was that the plan was 100% finished, which it clearly is not. No one yet, after the expenditure of about $1.5 million can answer the questions I raise with anything better that “Trust Us.” That’s not good enough. That’s too dangerous for Riverside. Ladies and Gentlemen, it still is not too late to prevent this fiasco from altering Riverside forever. But you must act.
King G - next time you see a Riverside Police Officer take a look at the shoulder patches they wear, and use for the Department logo.
