Chapter 5 – Environmental ConsequencesUSAG-HI activities and functions, general USAG-HI news that might be of interest to the public, andUSAG-HI services available to the public.To minimize traffic impacts on the surrounding community during construction, a construction trafficmanagement program would be implemented. The program would identify truck routes to limit trucktraffic to major streets.Intersection and Roadway Segment Operations. Traffic volumes adjacent to the new ranges at SBMRand PTA would increase slightly during and could result in modified traffic patterns. These trafficchanges would generally be due to redistribution of existing traffic within the SBMR or PTAproperties. No significant changes in traffic patterns or flows outside the SBMR or PTA propertiesare expected. Therefore, the traffic impacts on public roadways outside the Army installationsproperty would be less than significant, and no mitigation is necessary.No ImpactsParking. No parking impacts are identified at the range construction sites.5.2.7.3 Impacts from Live-Fire TrainingLess Than Significant ImpactsImpacts to local traffic. Under implementation of Alternative A, SBCT training would result in anincreased number of Soldiers training at all ranges. Traffic would increase slightly because a largernumber of Soldiers would use the existing and newly constructed live-fire ranges at SBMR and PTA;however, traffic impacts associated with intersection operations and roadway segments, and parkingare expected to be less than significant. No mitigation is necessary.5.2.7.4 Impacts from Maneuver TrainingLess Than Significant ImpactsImpacts to local traffic. Under this alternative, maneuver training would occur at SBMR, DMR,KTA, and PTA. Brigade- and battalion-level training would primarily occur at PTA, and thefrequency of maneuver training at PTA is not expected to increase above existing levels. TheKeamuku Parcel would be used for maneuver training as well, and would remain a nonlive-fire area.Platoon- and company-level training would primarily occur at the other areas, and would increase infrequency.Vehicle convoys would move personnel and equipment between the Army installations for maneuvertraining. Approximately 1,005 vehicles would be used for convoys, an increase of 346 vehiclescompared to current conditions. Stryker armored vehicles would be used for training. Soldiers wouldbe transported to ranges for training by convoys of Stryker armored vehicles and trucks.A convoy is normally defined as six or more military vehicles moving simultaneously from one pointto another under a single commander, ten or more vehicles per hour going to the same destinationover the same route, or any one vehicle requiring a special haul permit. Per command guidance,USAG-HI convoys normally maintain a gap of 15 to 30 minutes between serials (a group of militaryvehicles moving together), 330 feet between vehicles on highways, and 7.5 to 15 feet while in towntraffic. Per state regulation, military convoys are not authorized movement on state highways duringFebruary 2008 5-35 2/25th SBCT Final EIS
