This road will be used as the access route for YTA Demolition Range Phase 2 and 3, which willharden a 15.5-acre clearing. This project will improve access and control erosion by improving drainagethrough grading, establishing ditches, installing geotextile and fill material and confining activities tohardened surfaces.This project is located in the YTA and will improve an existing clearing into a 15.5-acre hardened pad.This facility will be used as a Light Demolition Range and will include a series of berms to separate thedifferent demolition stations. This project will extend upgrades made in YTA Demolition Range Phase 1and will improve access and control erosion by improving drainage through grading, ditching, removingoverburden to gravel or bedrock, installing fill material and confining activities to hardened surfaces.This project is located in the YTA and will improve a15.5-acre hardened pad installed in Phase 2. Phase 3will complete the Light Demolition Range through the installation of native seed and demo range trainingfeatures, including a hardened road section, chain link and plywood. This project will extend upgradesmade in YTA Demolition Range Phase 1 and 2 and will improve range use and control erosion byconfining specific demolition activities to appropriate areas and the seeding of berms and exposed soilareas.This project is located in the YTA and will improving a 1000 m existing trail to a 24-ft width, all-seasonsurface. In addition, a 2.5-acre pad will be hardened. This facility will be used to allow units to fire theirdirect fire system, Javelins and TOWs into the Stuart Creek Impact Area. This project will improveaccess and control erosion by improving drainage through grading, ditching, removing overburden togravel or bedrock, installing fill material and confining activities to hardened surfaces.The project is located in the cantonment area within the Local Training Areas 113 and 114 and willimprove 11 km of existing roads and trails and install concrete and earthen obstacle proficiency stations.The project will be installed in five 2.2 km phases and will provide basic and proficiency trainingopportunities through the negotiation of several different types of obstacles, such as side slopes, inclines,declines and self recovery areas. This project will improve access and control erosion by improvingdrainage through grading, re-establishing ditches, installing geotextile and fill material and confiningactivities to hardened surfaces.This project is located in the YTA and will install pre-fabricated ROMTEC SST Single Restroom latrinesat previously constructed Firing Points in the YTA, including FP Charlie, FP Bravo 1, FP Bravo 2 and FPBravo 3. Installing permanent latrines will eliminate the need for units from contracting portable latrineswhen conducting firing activities.This project will improve a 1200 m by 10 m section along the east side of Husky Drop Zone to apermanent year round access route and extend upgrades made in Husky DZ Road Access Phase 1. Thisproject will also provide a base for additional access improvements and the addition of an upgradedBattalion Staging Area adjacent to the drop zone. This project will improve access and control erosion byimproving drainage through grading, establishing ditches, installing geotextile and fill material andconfining activities to hardened surfaces.This project is located in the cantonment area and will install ROMTEC SST Single Restroom prefabricatedlatrine at the newly constructed Birch Hill Biathlon Range. The facility currently has no latrineassociated with it and is in an area open to public recreational use. This project will provide forappropriate and sanitary human waste disposal.This project will install approximately 37 acres of hazardous fuel reduction fire breaks on the west andeast borders of the Small Arms Complex (SAC). The 5000m by 30m (total of both sections) fire breakwill be mechanically cleared of all vegetation to the ground surface.This project is located in the cantonment area and will upgrade 7 acres of existing pads and roads with anadditional 6” of cap fill material, approximately 17,000 cy. This project will expand upgrades made inWarrior FOB Phase 2 and improve year round access to the site. In addition, it will facilitate erosioncontrol by confining activities to hardened surfaces.This project is located in the Small Arms Complex adjacent to Range Road and will upgradeapproximately 9 acres between the M203 Range and the MRFR by mechanically removing vegetationfrom a 100 m by 350 m section, hardening an access trail from the Range Road to the Range Area will behardened and installing a 100 m x 20 m x 5 m berm along the edge of the MRFR range. This project willimprove access and control erosion by improving drainage through grading, installing geotextile and fillmaterial and confining activities to hardened surfaces. In addition, range operation safety will beimproved through a containment berm.ApproximateAcresImpacted18.818.818.84.325.9130.43779.1_____________________________________________________________________________________________Environmental AssessmentUnited States Army Alaska, Integrated Training Area Management ProgramManagement Plan A-4
