This project will upgrade approximately 2.5 acres by clearingvegetation and hardening a 100 m by 100 m pad and a 100 m by 10 m access road. This project willimprove access and control erosion by improving drainage through grading, establishing ditches,installing geotextile and fill material and confining activities to hardened surfaces.This project is located within the cantonment area and will upgrade the existing parking area and trailnetwork, approximately 2 acres, to accommodate the Stryker Brigade. This area is currently onlyaccessible during frozen soils conditions. This project will harden the existing pad and trails and willimprove access and control erosion by improving drainage through grading, establishing ditches,installing geotextile and fill material and confining activities to hardened surfaces.This project is located in the YTA adjacent to Husky DZ and will upgrade an existing 24-acre clearing toaccommodate large scale brigade training exercises by hardening a 22-acre pad and a 30 m by 20 mlooping access road by installing an initial road/pad base. This project will be installed in three phases andwill expand upgrades made in previous Husky DZ projects. In addition, this project will improve accessand control erosion by improving drainage through grading, establishing ditches, installing geotextile andfill material and confining activities to hardened surfaces.This project is located in the YTA adjacent to Husky DZ and will upgrade an existing 24-acre clearing toaccommodate large scale brigade training exercises by hardening an intermediate cap on a 22-acre padand a 30 m by 20 m looping access road. This project will expand upgrades made in Husky DZ FOBPhase 1. In addition, this project will improve access and control erosion by improving drainage throughgrading, establishing ditches, installing geotextile and fill material and confining activities to hardenedsurfaces.This project is located in the YTA adjacent to Husky DZ and will upgrade an existing 24-acre clearing toaccommodate large scale brigade training exercises by hardening a final cap on a 22 acre pad and a 30mby 20m looping access road. This project will expand upgrades made in Husky DZ FOB Phase 1. Inaddition, this project will improve access and control erosion by improving drainage through grading,establishing ditches, installing geotextile and fill material and confining activities to hardened surfaces.This project is located on the Small Arms Complex and will upgrade the existing firing positions on theMPMG Range to accommodate Stryker access and provide for stable platform fire. This project willallow marksmanship training on all weapon system inherent to the Stryker vehicle at a home station.Upgrades will include pad hardening and the installation of concrete on the west and east sides of theMPMG Range access road. This project will improve access and control erosion by improving drainagethrough grading, establishing ditches, installing geotextile, fill material and concrete and confiningactivities to hardened surfaces.This series of projects will improve sections of existing road within the YTA and will re-establishhardened road surfaces and drainage features, including crowns, out/in slopes, ditches, water bars andculverts. These sections of road are characterized by poor drainage, insufficient and inappropriate roadbase and cap material, rutting and large erosion features, which impede access. These projects willimprove access and control erosion by improving drainage through grading, ditching, installing geotextileand fill material and confining activities to hardened surfaces.This project is located in the YTA and will cut a 40,000 m by 6 m survey line around the permanentimpact area. This project will create a mechanically treated, highly visible impact area perimeter that willimprove safety during training exercises and other operations adjacent to the impact area. It will alsoprovide a moderate firebreak.This project is located in the Tanana Flats and will cut a 30,000 m by 6 m survey line around thepermanent impact area. This project will create a mechanically treated, highly visible impact areaperimeter that will improve safety during training exercises and other operations adjacent to the impactarea. It will also provide a moderate firebreak.ApproximateAcresImpacted2.522424245Not YetDetermined510101059.344.5_____________________________________________________________________________________________Environmental AssessmentUnited States Army Alaska, Integrated Training Area Management ProgramManagement Plan A-6
