SBCT Final EIS - Govsupport.us

Graphics Code: D1Project Number: 58161Project Title: Land Easement/Road Construction between SBMR and DMRProject Location: SBMR route to DMRProject Size: 36 acres along 12.4 milesConstruction Timeframe: After March 2009Appendix D. SBCT Project DetailsBackground: Access to DMR from SBMR is via state and county public roads, with only a single twolanepublic road connecting the two locations. Military convoys using this road slow the flow oftraffic and create potentially dangerous situations when cars attempt to pass the military vehicles.Project Description: Acquire a perpetual easement of approximately 36 acres (15 hectares) andconstruct a 15-foot-wide (5 meter) gravel road with 3-foot-wide (1 meter) gravel shoulders on bothsides. The road would run 12.4 miles (20 kilometers) from SBMR to DMR and would provide militaryvehicle access to both installations. Work would include grading, paving, improving drainage, andinstalling culverts at stream crossings and guardrails at drop-offs. Storm drainage structures and lineswould be installed to prevent excessive amounts of stormwater runoff from water flowing over theroad and endangering traffic. Telecommunication lines would be provided alongside the new roadduring construction. Road grades steeper than 10 percent would be paved with asphalt or concrete andthe sides would be supported with shotcrete, guardrails, retaining walls, drainage structures (forexample, concrete and grass swales), and signs.Estimated Utility Requirements: NoneD-33
