Section view A-A is an inset around the StormTech Chamber Row with pavement, acceptable fill materials, aggregate backfill, concrete or stone headwall, rip rap scour protection and the concrete footing.

Section view B-B is an inset around the appropriate chamber cross section, aggregate backfill, ADS geosynthetic 601T non-woven geotextile, rip rap scour protection and the concrete footing.

Notes explain that chambers cannot be used as common conveyance culverts, open bottom culverts need scour protection, the design engineer must analyze the flows and velocities through the chamber system and design appropriately, headwall design is per local requirements.

Additionally, aggregate bottom concrete footing for low velocity stream crossing shows the plan, 2 sections with notes.

Charts listing acceptable fill material for the StormTech SC & MC Series Chambers with inset cross sections and notes are included.
