Spatial relationship and required clearances between a parallel pipe trench and a concrete footing. The pipe runs inside a backfilled trench sized per civil drawings, positioned parallel to the concrete foundation wall and footing. A minimum horizontal clearance of two feet is maintained between the footing edge and the adjacent trench. The bottom of the utility trench must remain above a line projected upward at a two-to-one slope from the bottom corner of the concrete footing.
