Motion carried. Voting Yes: Chairperson Riley, Councilmembers Johns and Kuzma. Voting <br /> No: None. <br /> 5. COMMITTEE BUSINESS <br /> 5.01: Consider Drainage Options for 173rd Avenue and Gibbon Street Area <br /> Civil Engineer II Linton reviewed the staff report and each of the options, noting that after the <br /> case was published, he realized it could be possible to create a cross section through the property <br /> as explained in Option 4. He said the wetland cannot be drained in an effort to make the water <br /> level lower than the home. He explained that while this may provide some relief, water seeks its <br /> own relief. The water, in this case, rose above the ground. <br /> Chairperson Riley asked why it would not work to dig a hole. <br /> Civil Engineer II Linton noted the natural level of the wetlands is expressed through the <br /> wetlands. If a hole was dug, the water level would be the same elevation as is expressed in the <br /> wetlands; it would not drop down. He stated it could provide more storage area. He related the <br /> action of the water and a hole to a cup and a serving bowl. Four inches of water in a little cup <br /> would fill it up, while the water level would be much lower in the serving bowl. The water is <br /> more spread out and shallow. <br /> Councilmember Shryock arrived at 6:05 p.m. <br /> Councilmember Johns inquired if the water will always be an issue in this area. <br /> Civil Engineer II Linton responded in the affirmative. <br /> Councilmember Johns asked how much water could be drained with piping added. <br /> Civil Engineer II Linton answered he could not be sure. The existing elevations will remain and <br /> make water drainage difficult. <br /> Chairperson Riley inquired whether the water table has risen over the course of time. <br /> Civil Engineer II Linton responded it has changed. <br /> City Engineer Westby noted the water level was very high in 2014. It does fluctuate. He said <br /> this issue will likely be a recurring problem without the pipe. He said the pipe may solve it and <br /> will at least provide relief. <br /> Civil Engineer II Linton stated if there is a heavy rain, the water could back up before it runs off. <br /> Councilmember Kuzma asked what the anticipated cost would be. <br /> Public Works Committee/June 16, 2015 <br /> Page 2 of 8 <br />
