Ditching and Culvert Replacement

• Shoulder width will be maintained and repair any damage from water erosion. • Shoulders will be lower and graded at a slightly steeper cross slope to provide positive drainage to the ditch. • When needed RIF RAF should be put in to prevent future washouts. • The depth of the ditch should be a minimum of 12” to 18” below the gravel base or follow the original ditch depth when constructed to maintain water flow to existing cross culverts and for water cutouts. • No gravel of sod berm or windrow will be left in between the road and the ditch slope. • Avoid any inconveniences to residents without prior notice given to them. • The contractor will use proper warning signs in and around the work area and only close one lane at a time during construction. • All unstable ditches and slopes will be properly protected against erosion according to best management practices and the contractor must be certified in that practice. Any exposed soil shall be stabilized with hay mulch at the end of the workday. • All culverts or obstructions the contractor will mark before work begins. • The contractor will call Dig Safe before any work begins and provide the Town Of Sullivan with the dig safe permit number. • A machine must have a hydraulic ditching bucket and not be any larger than a 23- ton excavator and no smaller than an 18-ton Excavator. The contractor shall avoid sharp turns on the hot top and avoid damage to the surface. Town of Sullivan Select Board reserves the right to reject and or all bids for any reason.
