vi. <br />Single Window Cuts by More Than One Utility Purveyor <br />Single window cuts made by more <br />associated with a private developmen <br />window cuts for restoration purposes. <br />Half -Width Overlays <br />a. Applicability <br />t <br />than one utility purveyor that are <br />project will be considered multiple <br />A full -width overlay shall be reduced to a half -width overlay without the need <br />for an EDDS deviation in each of the following circumstances, provided that <br />no pavement cut line is within 3 feet of the crown of the road: <br />• A longitudinal trench entirely on one side of the road crown; <br />• A single lateral trench, or multiple lateral trenches less than 200 feet <br />apart, made by the same utility entirely on one side of the road <br />crown; <br />• Multiple window cuts less than 200 feet apart made by the same <br />utility entirely on one side of the road crown; or <br />• A combination of longitudinal trenches, lateral trenches, and/or <br />window cuts made by the same utility entirely on one side of the <br />road crown. <br />b. Approximating the Crown of the Road <br />Since the crown of the road is not typically shown on project plans, the <br />pavement centerline will be used to approximate the road crown. If a road <br />is super -elevated, then the pavement centerline shall be used as a substitute <br />for the crown of the road. <br />c. Half -Width Overlay Limits <br />The half -width overlay limits extend laterally from the curb line or outside <br />edge of pavement to the crown of the road and longitudinally along the <br />roadway from 10 feet before the first pavement cut line to 10 feet beyond <br />the last pavement cut line. <br />d. Cuts Within 3 Feet of the Crown of the Road <br />If a trench comes within 3 feet of the crown of the road, a full -width overlay <br />is required from 10 feet before the first point at which the trench comes <br />within 3 feet of the crown of the road to 10 feet beyond the last point at <br />which the trench comes within 3 feet of the crown of the road as illustrated <br />in the examples in Figure 8 - 3. The remainder of the pavement may be <br />restored as a half -width overlay provided that no other pavement cut comes <br />within 3 feet of the crown of the road. <br />8-8 Engineering Design and Development Standards <br />September 17, 2021 <br />
