WRCC, Inc. Agenda Item 23c September 9, 2008 Page 4 of 6 Alternative 2: Conduct a new hydrologic study. This al ternative involves performing a new hydrologic study using current precipitation valu es and hydrologic methods to see if the dam and spillway would safely pass the presen t design storm without any construction. As- built plans would be required by the SEO, since the existing dam varies from the original plans from 1976. Alternative 3: Re-grade dam crest to a uniform height and conduct new hydrologic study. This alternative would be required by SEO if Alternative 2 demonstrated that the current spillway is not adequate. – Selected Alternative - Alternative 1 Fill low areas and re-grade dam crest to a uniform height: This alternative was selected so that the Comp any could preserve the storage in the Reservoir without having to complete a full hydrologic study. Spillway extension options: Alternative 1: Purchase the entire adjacent property from the current landowners and allow flows to continue across land. Alternative 2: Route channel directly through the center of the adjacent property. This alternative would require an easement over 30 acres. Alternative 3: Construct a channel close to the to e of the dam and direct flow along Company property with only 5.5 acre of easement needed over adjacent land. Selected Alternative - Alternative 3 - Construct channel close to toe of dam: This alternative was selected because it minimized the land disturbance a nd provided the shortest flow path back to the natural water course. Additionally, it kept the ma jority of the project on property already owned by WRCC, Inc. The cost of this alternative was about 70% less than the other alternatives.
