The permit area is within the water retention area of the Signal 1 Dam rehabilitation <br /> area. In short, the permit area will be underwater when the projects are complete. The <br /> Signal 1 Dam is considered a "High Hazard Dam"and therefore very complete soil and <br /> slope stability analysis have been completed in accordance with Department of Water <br /> Resources Dam Safety Division requirements. The soils in this area have been shown to <br /> be stable enough to support a "High Hazard Dam"directly on top of a 3:1 slope <br /> excavation. This slope stability analysis was run for steady seepage, end of construction, <br /> rapid-drawdown (soil drained, and soil undrained) and seismic scenarios. There was no <br /> setback from the 3:1 slope for the dam in these analysis'. Since both the KP Kaufman <br /> well and the ERN fence & road are located further away from the 3:1 slope than the dam <br /> was in the testing models, we request the DRMS accept the slope stability tests that <br /> were done by Earth Engineering Consultants as acceptable documentation of slope <br /> stability for this project. <br /> If you have any questions, please feel free to contact me and I will be happy to clarify. <br /> Sincerely, <br /> Don Summers <br /> Director, Todd Creek Village Metropolitan District <br /> 4 1 P T = <br />
