1 June 07, 2016 City of Fairfax Police Firing Range Expansion And Renovation Design City Council Work Session

2 Regulatory Requirements Existing Range Constructed 1985 prior to OSHA guidelines Range design requirements and guidelines: 29 CFR OSHA General Industry Lead Standard Laminar airflow at firing line between ft per minute 85 dba max noise in range Determinations: HEPA Filtered Ventilation System necessary to limit officer exposure to airborne lead Acoustical Treatments necessary to limit hearing loss due to range use 2

3 Police Training Requirements Live Fire Training requirements include: Marksmanship Low and No Light Training Scenarios Moving and turning targets for Static and Tactical Training scenarios Pre-programmed and Trainer controlled scenarios Larger firing line (8 lanes vs 6 lanes) provides more training area for live-fire drills and tactical team-movement exercises Determination: Range Design to Provide Capability for Expanded Live Fire Training Options 3

4 Police Training Requirements Simulator Training Integrates real world scenarios and images Shoot/Don't shoot scenarios incorporated to Enhance decision-making and de-escalation Skills for individual and teams 3-D scenarios and situational awareness training Determination: Include dedicated simulation classroom to provide for simulation training capabilities. 4

5 Condition of Existing Range Building Single wythe, unreinforced CMU wall construction not suitable for additional height or equipment loads Unknown bearing capacity of foundation Through wall cracking and shifting of existing CMU wall in multiple locations Wood truss roof structure not designed to support additional loads as required for range renovation Determination: Refurbishment will not be a good investment 5
