Alpha & Omega Group provided engineering services to the US Forest Service for improvements to four shooting ranges in the Nantahala National Forest of North Carolina. These improvements to the Dirty John, Panther Top, Moss Knob, and Atoah shooting ranges increase safety, minimize environmental impacts, and meet Americans with Disabilities Act requirements by following the latest federal, state, and local codes.

Each of the shooting ranges features covered target shooting stations with concrete floors and earthen berms behind the targets. A&O’s design considerations included:

  • A topographical survey
  • Mapping a shooting safety zone using LiDar, showing sign placement and trajectory maps for high-powered rifles
  • Acoustic insulation on the underside of station roofs
  • Ballistic sand backstops for recovering and recycling lead, (increased berm size and height)
  • Concrete pads and ADA-compliant sidewalks for the toilet facilities
  • “Hard” runoff controls such as filter beds to collect water, screening out larger lead particles and raising the pH of the water before draining it
  • Containment traps with vegetative cover to filter out lead bullet fragments
  • Ground contours to slow water runoff.
