(a) General. Utility facility design shall be accomplished in a manner and to a standard acceptable to the department. The location and manner in which a utility facility installation, adjustment, or relocation work will be performed within the right of way must be reviewed and approved by the department. Measures shall be taken to preserve the safety and free flow of traffic, structural integrity of the highway or highway structure, ease of highway maintenance, appearance of the highway, and the integrity of the utility facility. Utility facility installations shall conform with:

(17) Broadband Accommodation Process, found in the TxDOT Right of Way Utilities Manual, Appendix B.
(b) Location.
(1) Districts may have special provisions for utility facility installations based on constraints, needs, and practices in their areas.
(2) Utility facilities shall be located to avoid or minimize the need for adjustment for future highway projects and improvements, to allow other utilities equal access in the right of way, and to permit access to utility facilities for their maintenance with minimum interference to highway traffic.
(3) Longitudinal installations, if allowed, shall be located on uniform alignments to the right of way line to provide space for future highway construction and possible future utility facility installations.
(4) New utility facilities crossing the highway shall be installed at approximately 90 degrees to the centerline of the highway.
(5) The horizontal and vertical location of overhead utility facilities must conform with §21.41 of this subchapter (relating to Overhead Electric and Communication Lines), consistent with the clearances applicable to all roadside obstacles. No aboveground fixed objects will be allowed in the horizontal clearance. Underground utility facilities must conform to §21.40 of this subchapter (relating to Underground Utilities).
(6) Every effort shall be made to ensure that the proposed installation is compatible with existing and approved future utility facilities.
(7) A utility facility on controlled access highways or freeways shall be located to permit maintenance of the facility by access from frontage roads, nearby or adjacent roads and streets, or trails along or near the right of way line without access from the mainlanes or ramps. A utility facility may not be located longitudinally in the center median or outer separation of controlled access highways or freeways.
(8) On highways with frontage roads, longitudinal utility facility installations may be located between the frontage road and the right of way line. Utility facilities may not be placed or allowed to remain in the center median, outer separation, or beneath any pavement, including shoulders.
(9) If a utility facility extends across a railroad's right of way, the utility, before it may install that portion of the of the utility facility within the railroad's and department's right-of-way, must provide to the department a copy of the agreement that was executed by the railroad and that authorizes the utility to install the utility facility within the railroad's right of way.
(10) The procedures and requirements of this paragraph apply if a longitudinal installation is proposed within existing access denial lines of a controlled access highway or freeway without frontage roads.
(c) Plans. The plans must protect the public investment in the highway, inclusive of all its components, and maintain traffic capacity and safety for each highway user.
(1) All utility facility installations must be of durable materials designed for long life expectancy and relatively free from the need for routine servicing or maintenance. In addition to the requirements of this subchapter, any existing utility facilities to remain in place must be of satisfactory design and condition in the opinion of the district.
(2) Utility facility installation may not disturb existing drainage courses. In addition, soil erosion shall be held to a minimum and sediment from the construction site shall be kept away from the highway and drain inlets.
(3) Utility facility installations shall be planned to minimize hazards to, and interference with, future highway projects or other utility installations.
(4) Plans must include the design, proposed location, vertical elevations, and horizontal alignments of the utility facility based on survey data provided by a person registered by Texas as a registered professional land surveyor or the department's survey data, the relationship to existing highway facilities and the right of way line, and location of existing utility facilities that may be affected by the proposed utility facility.
(5) A utility shall verify the department's right of way line on the ground and procure any additional surveys required by the department before installing the utility facility.
(6) As-built plans or certified as-installed construction plans must include the installed location, vertical elevations, and horizontal alignments of the utility facility based upon the department's survey data, the relationship to existing highway facilities and the right of way line, and access procedures for maintenance of the utility facility. All as-built plans must comply with ASCE guidelines and standards. As-installed construction plans certified by a utility or its representative shall be submitted to the department for each relocation or new installation. In the alternative, if approved by the director of the Maintenance Division or Right of Way Division, a district may require a utility to deliver either as-installed construction plans that are certified by an independent party or final as-built plans that are signed and sealed by an engineer or registered professional land surveyor. In determining whether to authorize a requirement for independently certified or signed and sealed plans, the director shall consider:
(7) If approved by the director of the Maintenance Division or the Right of Way Division, a district may require a utility to deliver plans that are signed and sealed by an engineer. In determining whether to authorize a requirement for signed and sealed plans, the director shall consider:
(d) Tunnels and bridges.
(1) Fuel tanks, including storage tanks for petroleum or compressed gases, may not be within 100 feet of a highway structure.
(2) In providing a utility tunnel or utility bridge, the requirements in subparagraphs (A) - (I) of this paragraph apply.
