vi. Single Window Cuts by More Than One Utility Purveyor <br /> Single window cuts made by more than one utility purveyor that are <br /> associated with a private development project will be considered multiple <br /> window cuts for restoration purposes. <br /> viii. Half-Width Overlays <br /> a. Applicability <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 f=eet 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 />
