Infiltration Trench design is Volume Based using CASQA’s Stormwater BMP Handbook Approach
• Designed to store and infiltrate C3.d volume with 12-inch perforated pipe located approximately 3 feet above trench bottom (2 feet cover required for loading)
• Trench gently slopes towards dry well
Trench section was designed to meet H20 loading requirements
• Used Interlocking Concrete Pavement Institute Software to verify structural integrity and infiltration through pavers
