The minimum size for a garage sand trap shall be _______ feet.

The minimum size for a garage sand trap must be 2 feet by 4 feet to adequately accommodate the volume of sand, sediment, and other particulates that are typically collected from vehicles in a garage setting. This size allows for effective sedimentation and separation of materials, preventing them from entering the drainage system and causing blockages or contamination. A 2-foot by 4-foot dimension strikes a balance between functionality and spatial efficiency, ensuring that the trap can operate effectively without occupying an excessive amount of garage space. The minimum requirement is designed to comply with plumbing codes and best practices for stormwater management, ensuring that the system works efficiently in capturing and managing sand and other debris.
