Project NameDonnelly <strong>Training</strong> <strong>Area</strong>Buffalo DropZone AccessPhase 1Buffalo DropZone AccessPhase 2Project DescriptionThis project will improve a 1500 m section of an existing road leading into the Buffalo Drop Zone off of33 Mile Loop Road. The road intersects the Richardson Highway <strong>and</strong> is the main entry point for troopactivities within 6 major training areas. This section of road is characterized by relatively flat slopes thatare poorly drained with two significant erosion features <strong>and</strong> has received significant impacts from Strykertraffic. This project will improve access <strong>and</strong> control erosion by improving drainage through grading, reestablishingditches <strong>and</strong> the installation of geotextile <strong>and</strong> fill material.This project will improve a 5000 m section of an existing road leading into the Buffalo Drop Zone off of33 Mile Loop Road. This road is the main route for troop activities within 6 major training areas. Thissection of road is characterized by long open flat portions with soft areas that are insufficiently drained<strong>and</strong> has received significant impacts from Stryker traffic. This project will extend the length ofimprovements from BDZ Access PH 1 <strong>and</strong> will improve access <strong>and</strong> control erosion by improvingdrainage through grading, re-establishing ditches <strong>and</strong> the installation of geotextile <strong>and</strong> fill material.ApproximateAcresImpacted3.712.4Buffalo DropZone AccessPhase 3Meadows RoadUpgrade <strong>and</strong>Repair Phase 1Meadows RoadUpgrade <strong>and</strong>Repair Phase 2Windy RidgeRoad Upgrade<strong>and</strong> Repair Phase1Windy RidgeRoad Upgrade<strong>and</strong> Repair Phase2Buffalo DropZone Vegetation<strong>Management</strong> –BurnBuffalo DropZone Vegetation<strong>Management</strong> –MowThis project will improve a 6500 m section of an existing road leading away from the Buffalo Drop Zoneoff of 33 Mile Loop Road.

Maintaining safe drop zonecondition requires the removal of woody vegetation in favor of native grasses. Burning will be combinedwith rotational mowing to remove live stem <strong>and</strong> woody debris from within the drop zone boundaries. Thisproject will provide for the propagation of native grasses by improving soil conditions through theintroduction of burn residue <strong>and</strong> will maintain effective plant based erosion control by leaving rootmasses intact.This project will provide for effect vegetation management within the Buffalo Drop Zone through a 12-year rotational mowing cycle, with mowing taking place on years 4 <strong>and</strong> 10.
