CONCLUSION <br />Compliance with Standards <br />The drainage system for May Day Idaho Mine Complex — Wildcat Road was designed to meet <br />the La Plata County's drainage criteria. The site does include a F.E.M.A. mapped floodplain. <br />The existing Flood Insurance Rate Map (F.I.R.M) is presented in Appendix A and shows that the <br />flood hazard area is restricted to approximately ±200 feet on either side of the centerline of the <br />La Plata River with minimal impact. <br />Drainage Concept <br />The drainage system for May Day Idaho Mine Complex — Wildcat Road was designed to allow <br />storm water to be safely conveyed through and away from the site without negatively impacting <br />downstream or upstream properties (regionally) beyond that imposed by the historic condition. <br />All drainage facilities proposed with this development are private facilities to be maintained by <br />Wildcat Mining Corporation. <br />Sediment and Erosion Control Concept <br />The construction BMP's proposed for this site follow the requirements of the La Plata County <br />and recommendations by UDFCD. Attention to proper installation and maintenance are <br />essential for the sediment and erosion control practices to function properly. <br />ri r wssnCIATFS <br />Page 5 <br />
