Spatial coordination and separation requirements apply to underground utilities located in a corridor between buildings. A ten-inch fire main runs parallel alongside a sanitary sewer lateral, maintaining a minimum of one foot of vertical clearance. A storm drain main is positioned with six inches of minimum vertical clearance from adjacent utility lines. Slope requirements specify a two percent minimum fall across the varying width between buildings, with sidewalks sloping at two percent toward the property edges. Stub ends and fire connections are indicated for service extensions.
