About this file
This engineering detail sheet (C505) from Southern A&E, LLC shows construction specifications for erosion control and drainage features at the Rossville Middle School New Field and Concessions project in Walker County, Georgia. The document includes detailed technical drawings and specifications for multiple erosion control measures including filter rings, stone check dams, storm drain outlet protection, temporary sediment traps, and HDPE anti-seep collars.
The drawings provide specific measurements, materials, and installation requirements for each erosion control feature. Key specifications include stone check dam requirements for drainage areas under two acres, sediment storage calculations for two temporary sediment traps totaling 330.5 cubic yards capacity, and detailed cross-sections showing proper installation of riprap, geotextile fabric, and other materials. The document is certified by Patrick Hallahan (Level II Certified Design Professional #0000066587) and was issued for construction on December 17, 2024 with Addendum 1 dated January 10, 2025.
