Utility trenches and pier excavations are positioned near concrete foundations with strict excavation boundaries. No digging for pipe trenches parallel to the footing is permitted within the specified zone. Backfill and compaction must follow the geotechnical report recommendations. A one-foot-six-inch clearance is maintained from the footing edge.
