(a) General - All Installations. - (i) Each License Form E-54 and/or License Agreement shall have a drawing(s) attached which shows the current man-made and natural terrain features and how the proposed facility is to be constructed in order to miss obstacles within the highway R/W.
- (ii) Exhibits that show straight line construction with a standard offset distance are only acceptable if a field review by the WHD District confirms that construction along straight lines is practical. (See related Section on location within the R/W).
- (iii) If unanticipated or unusual circumstances are encountered during utility construction which force a deviation in excess of two feet from the approved horizontal alignment, the respective District Maintenance Engineer will be contacted prior to making the deviation, for approval of the deviation and an amended exhibit will be filed by the utility.
- (iv) As a minimum the exhibit will show the following:
- (A) The existing roadway, right-of-way line, right-of-way fence, and cross fences if they are not on the R/W line. Existing approaches, intersecting roads or streets, drainage ditches, irrigation ditches, pipes and culverts that have to be crossed. Existing major utility facilities. The proposed utility alignment with offset distances from either the roadway center line or right-of-way line.
- (B) Land description and accurate ties to the nearest highway milepost. If milepost markers are not available the tie shall be to a highway station.
- (C) Location of existing facilities on the highway R/W that are owned and/or operated by the applicant.
- (D) Proposed locations of all appurtenances like air relief valves, manholes, pedestals, junction boxes, line markers, vent pipes, guys and anchors, etc.
- (E) Size and or capacity of the proposed facility (i.e. kv, cablepairs, pipe diameter), pipe type and wall thickness for carrier and casing, product to be carried, as applicable.
(b) Aerial Crossings. - (i) In addition to the above, the exhibit will show the low sag design clearance above the high point of the roadway.
- (ii) Any existing or proposed underbuilt facilities, including those by others.
- (iii) Cross-sectional view of highway R/W showing the location of poles or support structures relative to roadway centerline or R/W lines. (Also see additional text).
(c) Buried Crossings. - (i) Cross-sectional view of highway R/W at the crossing, showing the depth of the facility relative to natural ground, roadway drainage ditch and roadway template.
- (ii) Location of bore and receiving pits.
- (iii) If casing pipe or conduit is used, show where the casing will end.
- (iv) If heavy wall thickness pipe is used instead of casing pipe, show where the heavy wall thickness pipe transitions back to normal thickness pipe. (Also see additional text).
