This detail outlines the geotechnical requirements for utility trenches located near foundation elements. It establishes a restriction zone prohibiting parallel pipe trench excavation within a specified boundary from the footing. Backfill and compaction must follow geotechnical report specifications. A slope ratio of two to one governs the excavation and soil profile below the footing bearing level.
