Chapter 5 – Environmental Consequences5.4.7 Traffic and TransportationTable 5-42 summarizes the potential impacts to traffic and transportation resources underimplementation of Alternative C. Under implementation of this alternative, traffic volumes on publicroadways in the ROI would increase from additional Soldiers and their families relocating to FTC andfrom construction activities. Convoys would travel from FTC to PCMS for maneuver training;however, convoy frequency would not increase compared to current conditions. Some of the trafficwould affect regional roadways currently operating at or near capacity. Based on the expected trafficimpacts, mitigation measures are proposed, and would reduce traffic impacts to less than significant.Table 5-42Summary of Potential Traffic and Transportation Impacts fromAlternative CLocationActivity Group Fort Carson PCMSImpacts from Cantonment Construction ☼ N/AImpacts from Range Construction ☼ N/AImpacts from Live-Fire Training ☼ N/AImpacts from Maneuver Training /+ = Significant + = Beneficial Impact = Significant but mitigable to less than significant N/A = Not Applicable☼ = Less than Significant= No Impact5.4.7.1 Impacts from Cantonment ConstructionLess Than Significant ImpactsConstruction traffic. No cantonment construction would initially be required to accommodate thepermanent stationing of the 2/25 th SBCT at FTC. During future construction that could occur, trafficon roads on Fort Carson and surrounding the post would increase temporarily. Construction trafficwould consist of construction vehicles and equipment, including bulldozers, graders, backhoes,excavators, dump trucks, cement trucks, and hoe-ram excavators. Transport vehicles would move theconstruction equipment to and from work sites.Construction traffic would be routed through Gate 3, Fort Carson’s primary commercial traffic gate,and continue south on Chiles Avenue. This is similar to current construction traffic patterns.Construction traffic would pass by a school at Chiles Avenue and Burris Street. Crossing guards arecurrently employed, and speed zones are enforced to ensure safety of school children in the area.Chiles Avenue is presently the primary route for commercial and construction traffic, and theintroduction of minimal amounts of additional traffic for temporary construction purposes would notnegatively affect school children. If needed, construction traffic can be rerouted onto Specker Avenueto avoid sensitive resources.On-post roadways may need to be temporarily closed during construction activities. Use of trafficcontrol procedures, including flaggers and posted detours, would minimize impacts to traffic flow.Other BMPs to address potential traffic impacts include minimizing construction vehicle movementduring peak rush hours on the installation and placing construction staging areas in locations thatwould minimize construction vehicle traffic within administrative, housing, and school areas.
