Conclusion: Long term solutions will involve hiring of a focused engineering team to design large scale improvements such as constructing new sections of concrete channels. The City should consider pursuing this, however it should be considered city-wide and not just for Tributary #4 and #6. In the meantime, keeping existing channels free of debris and overgrowth, updating & enforcing our subdivision ordinances for drainage retention, using the latest technology to digitally survey our city, and creating new overflow basins in strategic, city -owned lots will be the best immediate projects in my opinion as we move forward. City forces should be able to perform much of these smaller tasks and will do a great job to keep the costs down. Strong, two-way communication with the development community will also be key to successful future growth. As former Council Member Clifford stated at a City Council meeting on 4/24/17, "it sounded like with a 500 year event that no matter how much money they spent, they would not be able to stop the flood. " He also said the improvements the City had already done seemed to be making a difference. He is correct, and my goal is to work as hard as we can with the resources we have to make things better where we can. We cannot guarantee that flooding will never occur, particularly in the floodplain, but concentrated efforts where we can make small changes with significant impacts will be the best way to move forward in the near term to try to alleviate the issue in a financially feasible manner. 26
