These sections of road arecharacterized by poor drainage, insufficient and inappropriate road base and cap material, rutting andlarge erosion features, which impede access. These projects will improve access and control erosion byimproving drainage through grading, ditching, installing geotextile and fill material and confiningactivities to hardened surfaces.This project will improve the existing road and will re-establish hardened road surfaces and drainagefeatures, including crowns, out/in slopes, ditches, water bars and culverts.

Impacts from the use of the area are typical of military training exercises and include trailproliferation, vegetation damage, exposure of soil, road and trail degradation and impaired access. Theseimpacts, if left untreated, can decline and result in erosion and impaired drainage/hydrology. This projectwill mitigate training impacts by improving the health of existing vegetation through mowing, hydroaxingand fertilizing; the establishment of new vegetation in exposed area by hydro-seeding; the closingof unnecessary trails; the improvement of drainage through grading and the installation of water bars andculverts; and the reshaping and restoration of areas damaged by vehicles and equipment.This project will improve the existing road and will re-establish hardened road surfaces and drainagefeatures, including crowns, out/in slopes, ditches, water bars and culverts.

In addition, a 30 m by 30 m hardened pad willbe installed and a line of sight will be cleared from the OP to the Impact Area. This facility will be used toallow units to observe firing in the Stuart Creek Impact Area. This project will improve access andcontrol erosion by improving drainage through grading, establishing ditches, installing geotextile and fillmaterial and confining activities to hardened surfaces.3.8Bravo BatteryForwardOperations BaseCombined ArmsCollectiveTraining FacilityTrail UpgradeThe project is located in the Yukon Training Area adjacent to FP New Bravo and will improve an areaapproximately 4.5 acres to accommodate year-round vehicular traffic. In addition, an access road will beestablished to support entry and exit of this facility. An area approximately 2 acres will be thinned andtrails improved to allow access to a tent area. A latrine will be installed on site, along with several bermedareas for POL and maintenance activities. 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 within the cantonment area and will improve a network of existing trailsapproximately 1500 m in length to an all-season surface and width of 24 feet with adequate slope anddrainage. This project will improve access to the Fort Wainwright CACTF and control erosion byimproving drainage through grading, establishing ditches, installing geotextile and fill material andconfining activities to hardened surfaces._____________________________________________________________________________________________Environmental AssessmentUnited States Army Alaska, Integrated Training Area Management ProgramManagement Plan A-36.52.7
