- (a) Appurtenances shall be limited to those necessary for installation and maintenance of underground lines.
- (b) All above-ground appurtenances, including pedestals, manholes, vents, drains, rigid markers, valve pits, and regulator pits, shall be located outside the clear zone and as close to the right-of-way line as possible.
(c)
- (1) Service meters, master meters, cabinets, meter pits, pressure reducers, lift stations, pad mounted transformers, sprinkler pits, etc., shall not be located within the highway right-of-way.
- (2) Meters shall be located on the same side of the highway as the customer being served.
- (d) Utility accesses and valve covers for access to buried utilities shall be located outside the shoulder of the highway.
- (e) Manholes, valve boxes, valve pits, etc., shall be installed so that their uppermost surfaces are flush with the adjacent undisturbed surface and shall have sufficient structural capacity to withstand vehicular traffic.
(f)
- (1) Manholes shall not be placed or allowed to remain in the pavement or shoulders of high-volume roadways.
- (2) Exceptions may be allowed at those locations on noncontrolled access highways in urban areas where necessary for access to existing lines allowed to remain in place under existing or proposed roadways.
- (3) Manholes may be placed or allowed to remain in the pavement or shoulders of low-volume roadways in urban areas provided measures are taken to minimize such installations.
- (4) Placement of manhole installations should be avoided in the pavement at highway intersections.
- (5) Manholes shall not be located in a wheel path.
(g)
- (1) Manholes/handholes vary as to size and shape depending on the type of utility they serve.
- (2) To conserve space, their dimensions should be the minimum acceptable by good engineering and safety standards.
- (3) In general, the only equipment to be installed in manholes/handholes located on highway right-of-way is that which is essential to the normal operation of the utility, such as cable splices, relays, etc.
- (4) Other equipment, pumps, etc., should be located outside the limits of the highway right-of-way.
- (5) All manhole/handhole covers shall be flush with the ground or pavement surface, whichever is applicable.
(6)
- (A) All manholes/handholes shall be designed with sufficient structural capacity for vehicular loading.
- (B) Where soil conditions require, outside forms shall be used.
