Section 4: Drawing for Utility Installation Request FormsAnchor: #i1001037
Requirements for Drawing
One copy of the drawing should accompany each notice form. The drawing should show:
- the location of right of way lines
- frontage roads
- control of access lines
- main lanes
- proposed location of utility installation
- limits of encasement
- depth of cover (if applicable)
- all other pertinent data including a north arrow and the scale.
Control of access lines must be shown on the inside edge of frontage roads only when control of access is located between frontage roads and main lanes.
The proposed installation must be shown in a different color from the rest of the drawing, or otherwise clearly identified. Minimum size of drawing is 8½" x 11" and the drawing must be large enough to show all necessary details clearly.
In addition, it is recommended that utility installations in rural areas be described on a separate vicinity map which references the location of the installation to readily identifiable and permanent landmarks, such as the junction of state highways, river crossings, etc. It is recommended that one of the various internet sources be used to provide a vicinity map with GPS coordinates of the location.Anchor: #i1001102
A cross section drawing of all underground installations showing limits of encasement, if applicable, and depth of burial should be included if the proposed installation crosses the highway right of way. Any provision not included in the drawing must be included on the form or in a list of Special Provisions, which must be made a part of the request form. The drawing must also include:
- height of power and communications lines above highway pavements (when applicable)
- existing installations of the same utility
- whether the highway facility is proposed, under construction or completed and opened to traffic.
Requirements for Manholes
If manholes or above ground equipment housings are to be incorporated in the installation, they must be shown on the drawing, and a separate detailed drawing showing their dimensions must be included. Manholes and above ground equipment housings must conform to the requirements described in the Texas Administrative Code, Title 43, Chapter 21, Subchapter C and elsewhere in this chapter.
Future manholes that are to be located near existing manholes of the same utility line must be placed in line with the existing manholes. Offset manholes involve an excessive use of available right of way area and thus cause an undue burden on other utilities in securing an area for placement of their manholes or lines.Anchor: #i1001144
Bore Pits or Trenches in the Median
All installations which use bore pits or trenches located in the median or outer separation must include the following provisions, whether on the notice form or included in a Special Provisions page:
- Barricades, warning signs and other devices, as needed to comply with the Texas Manual on Uniform Traffic Control Devices, must be installed at any excavation or other work areas within 30 feet of lanes and ramps in order to adequately warn traffic and delineate obstruction and work areas.
- Trenches or bore pits must not be excavated where they may cause damage to roadways or to structures unless adequate and approved revetment is provided.
- No work will be undertaken within the controlled access area until adequate arrangements are made for its prompt completion.
