Roosevelt Drive Upgrade Study, MT BSilver Bow 2016(9) ENVIRONMENTAL SCAN 1.0 INTRODUCTION The Federal Highway Administration (FHWA), in partnership with Butte-Silver Bow City-County and the United States Forest Service (USFS), is completing a preliminary engineering study for construction alternatives to rehabilitate Roosevelt Drive which accesses the Beaverhead-Deerlodge National Forest. The study, referred to as the Roosevelt Drive Upgrade Study, will identify feasible improvement options to enhance recreational access, operations, and safety in the study corridor as well as reduce maintenance concerns based on identified needs. Roosevelt Drive begins at Montana Highway 2/US Highway 10, approximately two and one-half miles south of Butte, Montana in Silver Bow County. The roadway provides access to the Beaverhead-Deerlodge National Forest, recreational lands, and also offers access to Bureau of Land Management (BLM) lands and private residences. This Environmental Scan provides a planning-level overview of resources and identifies potential constraints and opportunities for the Roosevelt Drive Upgrade Study. The scan is not a detailed environmental investigation but is based on readily available environmental information for the study area. If improvement options are forwarded from the feasibility study into project development, an analysis for compliance with the National Environmental Policy Act (NEPA) and other applicable federal and state regulations will be completed as part of the project development process. Information provided in this report is intended to help support a future NEPA compliance process. 1.1 STUDY AREA The study area is located in Silver Bow County, Montana, approximately 2.5 miles south of Butte. The planning study area encompasses a 4.3-mile section of Roosevelt Drive, starting at mile post (MP) 0.0 and ending at MP 4.3 at the Roosevelt Drive Trailhead. The study area for this Environmental Scan is 0.5-miles wide, encompassing a 0.25-mile buffer from the centerline of the roadway along the 4.3-mile study section. The study corridor is shown in Figure A.1. The study area encompasses all or part of the following legally described areas in Silver Bow County: Township 2 North, Range 7 West, Sections 32 and 34 Township 1 North, Range 7 West, Sections 3, 4,
