This road is amajor access route for the eastern portion of the YTA and is characterized by a steep grade exceeding an18% slope, significant concentrated rill erosion and unsafe winter driving condition, including trackedvehicles. This project will re-establish a hardened road base with a maximum slope of 12% by installingre-routes, geotextile material and fill material and will improve access and erosion control throughgrading, ditching and the confinement of activity to hardened surfaces. In addition, this project willsignificantly improve safety during winter driving conditions.This project is located in the YTA adjacent to Johnson Road will improve a 4.5-acre section associatedwith FP Charlie by hardening a 30 m by 30 m pad and a 300 m access road and thinning a 2-acre tentarea. A latrine will be constructed on site along with several bermed areas for POL and maintenanceactivities. 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 in the YTA adjacent to the Stuart Creek Impact Area and will upgrade a 4 kmsection of existing road by spot hardening, clearing lines of sight and installing 2 target objective areas.This area is characterized by steep slopes, rill erosion, poor drainage and rutting. 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 in the YTA adjacent to the Stuart Creek Impact Area and will upgrade a 4 kmsection of existing road by spot hardening, clearing lines of sight and installing 3 target objective areas.This area is characterized by steep slopes, rill erosion, poor drainage and rutting. This project expandsupgrades made in Convoy Live Fire Range Phase 1 and 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 YTA within an area formally known as Lower Winter Camp. This projectwill include initial road/pad base hardening of a 500 m by 10 m access trail and a 150 m by 150 m pad.The DMPTR/IPBC FOB will expand upgrades made on previous Lower Winter Camp projects and willsupport bivouac activities associated with the DMPTR and IPBC Ranges. This project will improveaccess and control erosion by improving drainage through grading, establishing ditches, installinggeotextile and fill material and confining activities to hardened surfaces.This project is located in the YTA within an area formally known as Lower Winter Camp. This projectwill expand upgrades from DMPTR/IPBC Fob Phase 1 by installing an intermediate cap on a 500 m by10 m access trail and a 150 m by 150 m pad. 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 YTA within an area formally known as Lower Winter Camp. This projectwill complete upgrades from DMPTR/IPBC Fob Phase 1 and 2 by installing a final cap on a 500 m by 10m access trail and a 150m by 150m pad. 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 YTA TA 7 and will improve an existing firing point that is no longer inuseable condition. This project will upgrade approximately 2.5 acres by clearing vegetation and hardeninga 100 m by 100 m pad and a 100 m by 10 m access road. This project will improve access and controlerosion by improving drainage through grading, establishing ditches, installing geotextile and fill materialand confining activities to hardened surfaces.This project is located in the YTA Stuart Creek Impact Area and will improve an existing firing point thatis no longer in useable condition.
