Utility Trenches. It is highly recommended that where applicable, utility trenching be done prior to driveway excavation, using the future driveway for temporary spoils storage. If done early in the grading process, this will minimize disturbing more vegetation than necessary. Grading and Dust − Use of construction equipment should be limited to areas intended for specific site improvements to minimize damage to existing vegetation. Minimize dust with periodic sprinkling when necessary. State Codes must be observed prohibiting parking, driving or placing hardscapes over septic ▇▇▇▇▇ fields. Culverts − If called for, install the roadside culvert at the commencement of excavation. The edge of the pipe should be rounded or flared to improve flow. Place rocks around the inlet to prevent scouring. Culverts must discharge to a stable drainage way. Install a rock apron below the outlet (using 4”-6” rock) and a slope of no more than 1:2. Suggestion − A prefabricated galvanized flare at both the inlet and outlet is recommended to avoid collapse of the culvert and minimize erosion. The addition of a large boulder above each end has been found to minimize shortcutting by delivery vehicles. Permanent Control Measures: Driveway and Parking Area Stabilization – As soon as driveways and parking areas are graded, they are to be covered with a 4” compacted layer of Type 2 base. Infiltration Systems − Runoff from all impervious surfaces, including roof tops, driveways, and areas where the soil has been packed down, must be infiltrated in some manner. A typical system is a rock filled (infiltration) trench or basin (dry well).
Utility Trenches. Excavate trenches to indicated slopes, lines, depths, and invert elevations. Maintain 12 inches (300 mm) of working clearance on each side of pipe or conduit.
