This file contains civil site detail drawings for the Gas Alley Modernization Project at Fort Drum, New York. The drawings depict standard pavement construction details, erosion control measures, stormwater management infrastructure, traffic control devices, and site-specific installations. Concrete pavement specifications include 4,500 PSI strength with fibrilated fiber-mesh reinforcement, expansion joints at 50-foot intervals, and control joints at 5-foot spacing. Asphalt pavement details show standard and heavy-duty configurations with Superpave course specifications, subbase preparation requirements, and interface conditions. Erosion control details illustrate rolled erosion control product (RECP) installation on slopes and channels, silt fence specifications with 14-12 gauge reinforcing mesh, inlet protection systems, and check dam configurations for both temporary and permanent applications. Stormwater infrastructure includes storm pipe trenches, catch basin designs, infiltration trenches, and flared end section details with specific material gradations and geotextile fabric requirements.

Additional site details cover traffic control signage installation with breakaway supports, passive vehicle barriers including bollards rated for HS-20 loading, active vehicle barrier foundations, pavement markings including stop bars and crosswalks per MUTCD standards, and high-security fence specifications with corner post footings. All concrete work requires 4,000 PSI strength unless otherwise noted, and design standards reference Fort Drum specifications for construction materials, bond patterns, and installation procedures. The drawings indicate coordination requirements with existing utilities during construction and specify detectable warning systems, maintenance clearances, and expansion joint sealant requirements. Construction sequencing notes address temporary versus permanent structures, substrate preparation protocols, and field inspection procedures for critical elements such as infiltration basin installation and tracer wire system continuity testing.
