The project location map is attached for reference. <br /> <br />Slope sloughing along the north slope of Swan Creek Diversion, south of the wastewater primary <br />cells 1 and 2, was first noticed by city public works spring of 2021. Vertical displacement at the top <br />of the slope is approximately two (2) feet with the west end of the sloughing starting near the dike <br />between lagoon cell 1 and cell 2 and continuing east a distance of approximately 180 lineal feet. The <br />proposed project is to repair the existing slope sloughing, thus reducing the risk of further sloughing <br />and critical failure of the slope. Critical slope failure could lead to the emptying of the primary lagoon <br />cells into Swan Creek, which would cause flash flooding downstream in addition to environmental <br />impacts. <br /> <br /> Figure 1.
