Local View: Where will the water go?

I found the recent numerous articles published in the Lincoln Journal Star concerning flood plain issues very interesting.

However, I feel several issues mentioned in the articles should be elaborated upon.

I will begin with the editorial opinion regarding Dead Mans Run and ask this question: If Salt Creek is full, where will the drainage from Dead Mans Run go?

It is totally senseless to invest upward of $50 million in Dead Mans Run and still allow fill to be placed in the flood plains of Salt Creek and its tributaries with the blessings of the so-called flood plain experts of the city of Lincoln.

Also, the editorial opinion mentioned the Antelope Valley project and Antelope Creek. Again I will ask the question: If Salt Creek is full, where will the drainage from Antelope Creek go? In addition, there would be a very good possibility that a water dam could be created at the convergence of Antelope Creek and Salt Creek.

Keep in mind, 11 tributaries drain into Salt Creek.

Perhaps the main beneficiary of the Antelope Valley Project might be the University of Nebraska, which as a result of the project had 56 acres of property removed from the flood plains.

Also mentioned in the editorial was the Salt Valley dam/lake system. Be advised, the Salt Valley system has a projected life of 50 years.

The levee system was a joke to begin with because of the inferior material used to construct same.

A recent article in the Lincoln Journal Star included statements made by Nicole Fleck-Tooze of the city Public Works Department concerning the Oak Creek levee system in the airport area not meeting supposed new levee standards of 100-year protection, and the high cost of upgrading the levee in turn raises questions about the Salt Creek levee system.

What about the Salt Creek system and its 50-year protection? I might add that during numerous public hearings, Fleck-Tooze said the actual figure was 35 to 50 years. This levee system is supposed to be protecting to some extent 3,000-plus residential properties and 200-plus businesses.

One would think that if nothing else common sense would tell those responsible that priorities should be to either solve or lessen the Salt Creek potential for a major flood.

Two very good examples of mismanagement would be Holmes Lake, which lost eight feet of storm water storage because of silt, and the Beal Slough fiasco, which is in and out of the flood plain so many times it will make your head spin.

Let’s not forget the Cardwell Branch mess and the supposed loss of flood plain maps.

Last but not least, where are the emergency shelters located and the location of same advertised or posted?

I am grateful for the articles in the Journal Star. However, I feel there are far too many unanswered questions just as Robin Eschliman found in her questioning of city Public Works staff.

In 14 years, my flood plain insurance bill has increased from $142 per year to $335 per year. That is for basic structure and does not include content, which incidentally would range from $500 to $600 per year.

" Excellent questions. I have often wondered the same.

Why aren't we looking at expanding the levee system for Salt Creek and providing a wider channel for that volume? Widening the distance of the levees from the banks by even a few additional feet and re-strengthening them should be something that needs to be considered. While I don't have the foggiest as to the math on the volume a 3-4 foot shift (should probably be 10 - 15 feet to get a real value from it) backward would add, I am guessing it is in ten of thousands of cubic foot volume capacity that would serve to protect many areas of Lincoln, and alleviate back flow and water dam issues.

I questions our ability to control any part of nature, but preventative measures are due and should be considered before more expansion in to these lower lands continues. I hope that "our leaders" are using some foresight for similar protections for Stevens Creek on the east side as well. I hope that they are not allowing developement to be to close that we have the same issues there as Antelope, Dead Man's, Beal Slough, Middle, Caldwell, Oak, etc. "

" Thank you Danny for getting to the meat of the matter. Salt Creek is where the big flood is going to come from. Why have we spent nearly $300 million on Antelope Valley? Besides the obvious land grab motives of UNL and 2015 I haven't a clue. This city loves their studies. Did they do a study to determine where the flood danger was and what the best and most cost effective solution was? Or did they listen to UNL and 2015 and decide where the nicest crop of political hay could be cut? "

" Is Danny Walker a hydroligist? I am seriously asking because he goes on and on at City Council meetings about floods and flood plains. It sounds in his letter like he might know what he's talking about, but does he have formal education, training or work experience in the field of hydrology, geography, regional planning, construction management, civil engineering, architecture or meteorology? "

" It should be pointed out that the 50 million dollars for Deadmans Run will buy stormwater storage in the Deadmans Run watershed and be released after the storm has passed. Therefore the Deadmans Run improvements should help Salt Creek's capacity. "

" just wondering; Mr. Walker meets or exceeds all requirements needed to qualify as a floodplain expert. One would have to be a complete idiot to not realize the negative impact of filling the floodplain. EXAMPLE: when he was a young boy he filled the bath tub with dirt to play in. Later on, mom told him to take a bath so he turned on the bath water and the water had no place to go and ran all over the floor. He said his mom was really mad. He did miss one point, that being the hundreds of thousands of dollars spent on Dead Man Run to save UNL Ag Campus pecan trees. "

" Would the experts please explain to me why all the money was spent on Beal Slough to remove the residential properties from the floodplain? Then guess what, Beal Slough areas were placed back into the floodplain after new mapping. I am glad we have experts in this town. "

" If our stormwater system is in such sad shape why is the mayor using stormwater bond issue money as a come on for home buyers? Is that LEGAL? "

" Just take a trip on north bound 180 past Superior and look to the East and check out the mess created to control Linn Creek and other run off and then think back how beautiful the area once looked. JUST ABOUT AS SMART AS BUILDING HOUSES OVER LINN CREEK ON NORTH 1ST. STREET. "

" Have you noticed the floodgates and floodwall around the LES headquarters on North 27th? Guess who paid for that. Also, I think Jeff meant 180 North of Cornhusker NOT Superior. "

expert wrote on July 11, 2008 12:38 pm:
" Lesson #1: The term "100-year flood" is often incorrectly used and can be misleading. It does not mean that only one flood of that size will occur every 100 years. The term is a statement of probability that scientists and engineers use to describe how one flood compares to others that are likely to occur. Today, we use the phrase "1% annual chance flood" What it means is that there is a 1% chance of a flood of that size happening in any year. Over a 100-year period, it has a 63.5% chance of occurring. Even more surprising is that over a 30-year period (typical mortgage period) the 1% annual chance flood has a 26% of occurring means a home in the mapped flood hazard area is five times more likely to be damaged by flood than to have a major fire. End of lesson. "

" concerned by Deadmans Run: Think about it, IF Salt Creek floods Deadmans Run will ALSO flood as will the other eleven (11) tributaries. In essence FIX THE MAJOR PROBLEM FIRST. Huge lack of intelligence shown on the part of whoever thought up the idea of blowing 50 million plus on Dead Mans Run. "
