Director of Engineering and Public Works P.O. Box 478 Coppell, TX 75019 Dear Mr. Griffin: I am forwarding your request for information to Ms. Sue F. Reid, in the Dallas District office. Ms. Reid handles these requests for the district. Her staff should be contacting you soon about the cost of the copies and to make arrangements for you to pick them up. If the GTE and the City of Coppell can agree to a plan to share the utility accommodation area, without damaging the trees, TxDOT approval should not present a problem. GTE can get permission from this office to move their line at such time as they request to do so, providing they do not do irreparable damage to the root system of the trees. In some locations. it is has been necessary for these installations to be bored, to avoid killing trees. If they are willing to move their line, as Mr. Casteel states. there would be no need to meet. Another option might be for GTE and/or the City of Coppell to replace the trees at another a~eeable location on SH 121 Right of Way and maintain them for a period of time necessary to assure survival. If that is an option you feel you want to pursue, we would need to involve our landscape architect in the process (to determine species, replacement ratios, and a proper length of maintenance period). Several meetings might be needed. I am asking Mr. Nabors to contact you next week about a possible meeting. Since there is some question in my mind about statements attributed to him and Mr. Rawlings, I would like for them both to be present. Claud P. Elsom III, P.E. Area Engineer cc: Sue F.

Their contention was and stir is that such work would involve heavy machinery disturbing the "drip line" of the existing oak trees and flow line of the R.O.W. contour. Since nly last conversation with Hendricks, I have received his letter requesting this cable be relocated. I am formally advising you that GTE must not relocate, alter or even dig along that state right-of-way without the express written permission of TXDOT. We can appreciate the importance of the water line and the completion of this project. If the line is to be placed the apparent options are either change the mind of the Highway Dept. or adjust your water line, (depth / all~tmment). GTE must abide by the decisions and mandates of the State in relation to the roles and guidelines governing their highway right-of-ways.

As outlined in the July 30th memorandum, the City of Coppoll has a p~n.it from the Texas Department of Transportation for the construction of this water line within the Staro's right-of-way. The City's water line was permitted for a distance of 10-feet off the right-of-way line and the project aligrm~ent was set using the staro's right-of-way markers and right-of-way strip map (not the fence lines or tree line). It is very likely that the permit issued to GTE by Texas Department of Transportation provides for a specific location of your facility also. We suggest you review the permit and determine if your communication line was constructed in accordance with the permit issued by TxDOT. As of the date of this letter, Mr. Larry Davis with the City of Coppell reports no relocation efforts have been completed by GTE. Mr, Davis has explained that apparently you are experiencing some difficulUes with the Texas Department of Transportation relative to your relocation; however, we have received no written explanation, schedule or request for assistance GTE. The construction of this 12-inch water transmission main is critical to the proper operation of the City's water system and the health, safety and welfare of the public, It is vitally important that this water line be completed immediately so that the City can provxde adequate service and fire pro~eetion to developments in this area of the City.

B 3067 Da~ Re: City of Coppell S.H. 121 Water Line: From: Sandy Lake Road To: 675-feet south of Corporate Drive Dear Fir. Allen: At the request of the City of Coppell, we are submitting this preliminary set of consreaction plans for the S.H. 121 Water Line project, from Sandy Lake Road to 675 feet south of Corporate Drive. This submittal is being made in advance the formal Notice of Proposed Installation on Controlled Access Highway (TxDot Form I082), which the City will submit at a later date. The purpose of this preliminary submittal is to get the state' s determination concerning two alignment issues: It is our understanding the State' s Utility Accorrtmodation Policy provides for communication facilities to be installed in the first 3-feet of right-of-way, with water and sewer lines to be installed between first 3 to 10 feet of the right-of-way. Based on preliminary discussions with your office, we have set the water line alignment 1 O-feet inside the existing fight-of-way of S.H. 121. During our field surveys for this project, we noted a recently installed underground telecommunications line (fiber optic?) meandering up to and beyond 10-feet inside the existing fight-of-way. The location of the recently installed cable is shown on our construction plans in accordance with the new trench line we found. We believe this facility is owned by Co-serve Communications. Is there a Notice of Proposed Installation on file in your office for this facility and does it provide for a definite alignment? What recourse does the City have if this facility is in conflict with the Notice requirements you have on file? The City of Coppell has requested the State consider an alignment exception to the normal Utility Accommodation Policy for a portion of the proposed water line. Please refer to. The alignment exception is between water line station 19+80 and 22+39 as marked up on construction plan sheets 3 and 4 and is made in order to facilitate the construction of the water line across the drainage channel at the ouffall of the 66-inch pipe culvert. The revised alignment will also minimize the removal of trees and ease maintenance of the water line in the future. ~,..iZAllen, P.E. ~ -l:~partment of Transportation ,~ber 19, 1998 //Ipage No. 2 Please clarify the permitted alignment of the Co-Serve telecommunications cable and review this request for an alternate alignment for the City's proposed water line.

Hendricks, PE Shimek, Jacobs & Finklea, 8333 Douglas Ave, # 820 Dallas TX 75225-5816 L.L.P. Dear Mr. Hendricks: In regards to your October 19, 1998 letter concerning the two alignment issues, TXDOT offers the following. 1. TXDOT provides for aerial utilities to be placed in the first three feet of the right of way. Three to ten feet is for any underground utility. The Dallas District generally does not dictate the alignment for any utility. Only that the alignment must be a set distance uniform with the right of way line. 2. As far as exceptions to deviate from the ten foot alignment, TxDT only considers this option when the first ten feet is full of utilities and other considerations warrant such justification. If the existing fiber lines deviates as indicated in your letter, the owner of the fiber cable will either have to completely adjust the line or more the necessal-y areas in conflict to prevent the cable from being cut during the installation of the water line. At this point, TxDOT does not consider adequate justification exists to warrant an exception. As for the existing trees, if the city is unwilling to remove them, the water line can either be bored under the trees or placed on easement. If you have any questions please contact Murray Allen at (214) 320-6648. An Equal OpportuniP/ Ernl~lo),er SHIMEK, JACOBS & FINKLEA, L.L.P.

GENERAL~. - 'All poles and'inline'guys shall be kept within one (1) foot ofthe right of way line. Guysset at right angles to the right of way line shall .not protrude into.the right of way more than three (3) feet. On curved sections a pole may be placed at three (3) feet with a guy placed~on..the right of way line. ._ ___-. For crossings, a minimumvertical clearance of eighteen (18) feet for aerial 'communication cables and twenty two'(22) feet for aerial electric conductors shall be provided above the pavement surface, · except as noted in item #3 below, Vertical clearances for longitudinal lines are governed by the National Electri= Safety Code. Conductors shall not be permitted to longitudinally overhang the pavement surface. All crossings must be made at or near right angles to highway. 'No poles will'be permitted in the center medians ofdivided highways. Poles Will only be permitted in the outer separations of controlled access facilities. Under no circumstances will aerial lines be permitted to cross. diagonally across .an intersection. 2. STEEL POLES -. Ste~l poles with bases greater than thirty six (36) inches shall not be placed in .the right of way except in extreme hardship situations and if sufficient space remains for other utilities and will only be considered as exceptions. 3. CROSSINGS AT BRIDGE STR~CT~RES- A minimemhorizontal distance of one hundred fifty (150) feet or a minimumvertical clearance of thirty (30) feet must be provided from the lowest conductor to the top of the bridge deck. 4, JOINT ~S~ OF FACILITIES - The placement of dual pole lines longitudinally within the right of way will not be allowed. In areas where a pole line ~urrently exists utility agencies will be required to enter into an ~greement for joint Use of a single pole line. TRENCH EXCAVATIONS AND PIT_ LOCATIONS 1. GENERAL - No dirt from a trench or pit excavation shall be placed on the roadway or shoulders. All equipment and stockpiled dirt shall meet the safety clear zone distances listed below or have adequate barricades and warning devices to protect the traveling public. Topsoil shall be kept separate from other excavation material, and be replaced in accordance with "SPECIFICATIONS FOR BACKFILL." All pits and trenches shall be kept free from standing water. If trenches and/or bore pits are left open for extended periods of time without a continuous progression of work, the utility will be required to backfill the trench and/or bore pits. Any other pit will not be left open for more than a forty-eight (48) hour period. In all excavations where sloughing is likely to occur, shoring will be utilized to prevent damage to the highway structure(s). The utility agency or contractor shall be responsible for maintaining trench excavation protection as required by provisions of Part 1926, Subpart P - Excavations, Trenching and Shoring of OSHA Standards. 2. TRENCHING - Longitudinal installations must be placed as near a uniform alignment to the right of way line as possible. Trenching machine or backhoe may be used. A backhoe will be required if a uniform alignment can't be maintained by use of a trenching machine. 3. SAFETY CLEAR ZONE DISTANCES - Minimum clear zone distances required for trench excavations and bore pit locations are as follows. For UNCURBED HiGhways. A. Thirty (30) ft from the edge of pavement (Traveled Lane) of high-speed (More than 40 mph), high volume (More than 750 vehicles per day) highways. B. Sixteen (16) ft* from the edge of pavement of high-speed, volume (Less than 750 vehicles per day) highways. C. Sixteen (16) ft* from ramps. D. Ten (10) ft* for low-speed (40 mph or less) highways. E. Ten (10) ft* for any paved intersecting side streets. low * Five (5) ft MINIMUM from the edge of any shoulder. For CURBED HiGhways. A. Thirty (30) ft from the back of curb for high-speed highways. B. Five (5) ft from the back of curb, plus any additional distance to clear sidewalks, for low speed highways. C. Five (5) ft from the back of curb for intersecting side street. BACKFILLING 1. GENERAL - As soon as practical, all portions of the excavation shall be backfilled. Trenches and pits shall be backfilled with the material obtained from the excavation or from other sources. BaCkfill material will be free from stones of such size as to interfere with compaction; free from large lumps which will not break down readily under compaction; and free from frozen lumps, wood or other extraneous material. The TxDOT Inspector may reject any material containing more than twenty (20) percent by weight of material retained on a three (3) inch sieve. The portion of top soil removed from the original excavation shall be replaced, as nearly as feasible, in its original position. 2. DEPTH OF LIFTS - That portion of backfill below the top of pipe shall be placed in uniform layers not to exceed eight (8) inches in depth (loose measurement). Backfill above the top of pipe shall be placed layers not to exceed ten (10) inches in depth (loose measurement). If the backfill is to support a portion of roadway or embankment, then the material will be placed in uniform layers not to exceed eight (8) inches in depth (loose measurement). 3. PROCEDURE FOR COMPACTION ~ Each layer of backfill material, if dry, shall be wetted uniformly to the moisture content required to obtain a density comparable with the adjacent undisturbed soil and shall be compacted to that density by means of mechanical tampers or rammers. The use of rolling equipment of the type generally used in compacting embankments will be permitted on portions which are accessible to such equipment. Water jetting or ponding will not be permitted. Special care shall be taken to ensure thorough compaction of material placed under the haunches of the pipe. · Cohesionless materials, such as sand, may be used for general backfilling purposes. Compaction of cohesionleSs materials shall be done with vibratory equipment. 4. RESTORATION OF RIGHT OF WAY - Prompt replacement of sod, removal of debris, and any other restoration necessary to restore the right of way to a condition equal to that which existed prior to the utility installation will be required. In areas of erosion, the use of stabilized backfill may be required. Should settlement or erosion occur within six(6) months of the utility installation, the utility agency will be required to reshape, reseed, and/or resod the area. '.' CONSTRUCTION OF HIGHWAY CROSSING~ ':BY BORING 1. GENERAL - WATER JETTING OR JACKING WILL NOT BE PERMITTED. All paved streets which are maintained by TxDOT must be bored & encased unless it is specifically stated on the permit that an exception for open' cutting and/or no encasement is granted. At no time shall the boring operation interfere with the traveling public. The safety of the traveling public and maintaining the integrity of the roadway is the primary concern. 2. BORE PIT LOCATIONS - No excavation. for bore pits will be allowed to be any closer to the edge of the pavement (travel lane) than as outlined in the "TRENCH EXCAVATIONS AND PIT LOCATION" specification. If the required clear zone distance is closer than outlined in the above mentioned specification, then appropriate traffic control devices such as barricades, signs, barrel mounted guard fence and/or concrete traffic barriers will be required as deemed necessary by the TxDOT inspector. No excavated material will be stored closer to the traveled way than the bore pit. All pits and trenches shall be backfilled immediately after the encasement and carrier pipes has been installed. Upon completion of the backfill, all excess material will be removed from the right of way. 3. METHOD OF INSTALLATION - Crossings are to be installed by the AUGER or "DRY" BORE method and shall beaccomplished by use of a laser sighted bore machine or a bore machine .requiring a pilot hole. The pilot hole will serve as the centerline of the larger diameter hole to be bored. The use of water or fluids in the boring operation will only be allowed for lubricating the cutting head. The boring operation shall be performed from the low or.downstream end. Lateral or vertical variation of the encasement pipe from the · proposed line and grade will be permitted only to the extent of one (1) inch in ten (10) feet, provided that such variation shall be regular and only in one direction. ' The encasement pipe shall be approximately the same diameter as the bore hole. Overcutting in excess of one inch shall be remedied by pressure grouting the entire length of the installation with a mixture consisting of two (2) sacks of cement per cubic yard of sand. 4. OPTIONAL WET BORES - The utility or contractor may request installation by the Slurry or "Wet" bore method. The approval to wet bore is granted by the Area Engineer or his designated representative on an individual permit basis. If the a~ea office allows wet bores in their designated area, approval will be based on bore size and soil conditions- Wet bores should be restricted to areas of rock or other suitable material which will prevent the sides of the bore hole from "caring in". A geotechnical report may be required prior to approval. In no instance will wet bores be allowed to exceed eighteen.(18) inches in d~ameter. The amount of water used for creating the slurry will be such that little or no runoff is encountered. If, in the opinion of the TxDOT inspector, at any time during the boring operation inadequate conditions are encountered for performing the wet bore, the process will be stopped and the bore will be completed by Auger bore. The slurry material removed from the bore may not be used in the backfilling of the bore pit. 2 WATER AND SANITARY SEWER INSTALLATIONS 1. GENERAL - Longitudinal water and sanitary sewer pipelines shall be placed on uniform alignment three (3) to ten (10) feet from the right of way line. The minimum depth of uover shall be twenty-four (24) inches for non-plastic lines and thirty (30) inches for plastic lines. If a nonmetallic line is installed, a durable metal wire or other device shall be concurrently installed for detection purposes. Each line may be installed with enough vertical flexibility to prevent excessive stresses, however, horizontal "snaking" of the line is prohibited. The utility agency shall place identification markers at the right of way line in sufficient number for longitudinal installations and at each highway crossing.

When the city does not have a utility accommodation policy and/or customary practice, the provisions of this undesignated head concerning utility accommodation should be used as a guide. (c}The provisions of this undesignated head concerning utility accommodation will not be applied to utility facilities presently locate~ within the rights-of-way of con~Dleted highways for which agreements with the department were entered into prior to December 31, 1988. (d) Various tJq}es of utility lines not specifically covered herein shall be considered within the provisions of this undesignated head concerning utility accommodation in accordance with the nature of the line. It shall be a general practice to consider all lines carrying caustic, flammable, or explosive materials under the provisions for highpressure gas and liquid fuel lines. §21.34. Scope. These sections govern on matters concerning acconmnodation, location and methods for the installation, adjustment, relocation, and Plate 8 Sheet 8 of 47 State Department of Highways and Public Transportation Right of Way Division UTILITY MANUAL maintenance of utilities on highway rights-of-way, but do not alter current authority for their installation nor determination of financial responsibilities for placement or adjustment thereof. Where industry or governmental codes, orders, or laws require utilities to provide a higher degree of protection than provided herein, the higher degree of protection shall prevail. §21.35. Exceptions. Exceptions to any design, location or methods of installation provisions contained in these sections'may be authorized by the bridge engineer, chief engineer of highway design or chief engineer of maintenance and operations, whichever is applicable. Exceptions for form and/or property rights may be authorized by the right of way engineer and/or chief engineer of maintenance and operations. In addition, exceptions in unusual cases may require approval of the administration. Requests for exceptions will be considered only where it is shown that extreme hardship and/or unusual conditions provide justification and where alternate measures can be prescribed in keeping with the intent of these sections. All requests for such exceptions shall be fully documented with design data, cost comparisons, and other information that may be pertinent. §21.36. Authority of Utilities. (a} Under existing state laws, various utility firms and agencies have a right to install their lines along and/or across highway right-of-way. This ~i Plate 8 .... j Sheet 9 of 47 State Department of Highways and Public Transportation Right of Way Division UTILITY MANUAL includes those firms which are authorized by the laws of this state to transport and/or distribute natural gas, water, electric power, telephone (including cable television), and salt water and those which are authorized to construct and operate common carrier petroleum and petroleum product lines. (b) Private lines should normally be allowed to cross, but should not be permitted longitudinally on the highway right-of-way. This includes but is not limited to privately owned lines from gas or oil wells, lines owned by oil companies within .refinery and oil storage complexes, by firms which are engaged in businesses other than those described in subsection {a) of this section, and domestic lines owned by individuals. §21.37. Location. (a) Utility lines shall be located to avoid or minimize the need for 'adjust- ment for future highway improvements and to permit access to the utility lines for their maintenance with minimum interference to highway traffic. (b) On controlled access highways, the location shall permit maintenance of the utility by access from frontage roads where provided, nearby or adjacent roads and streets or trails along or near the highwa) r~ight-of-way line, to the extent practicable, without access from the through traffic roadways or ramps. (c) New utilities will not be permitted to be installed longitudinally within control of access lines of any freeway, except that in special cases such installations may be permitted under strictly controlled conditions. However, in each such case the utility owner must show that: Plate 8 Sheet lO of 47 State Department of Highways and Public Transportation Right of Way Division UTILITY MANUAL (1) the accommodation will not adversely affect the safety, design, .construction, operation, maintenance or stability of the freeway; (2) the accommodation will not be constructed and/or serviced by direct access from the through. traffic roadways or connecting ramps; (3) the accommodation will not interfere with or impair the present use or future expansion of the freeway; and, (4) any alternative location would be contrary to the public interest. (This determination would include an evaluation of the direct and indirect environmental and economic effects that would result from the' disapproval of the use of such right-of-way for the accommodation of such utility.) (d) Where a utility already exists within the proposed right-of-way of a freeway and it can be serviced, maintained, and operated without access from the through traffic roadways or ramps, it may remain as long as it does not adversely affect the safety, design, construction, operation, maintenance, or stability of the freeway; otherwise, it must be relocated. (el The longitudinal installation of a utility between the right-of-way line and the frontage road will not violate control of access in those control areas near ramp terminals. (f) When longitudinal installations are proposed within existing access control lines as special cases and meet the conditions under subsection (c) of this section, a utility strip shall be established by locating a utility access control line between the proposed utility facility and the through roadway and ramps. Existing fences shou1 d be retained and, except along sections of Plate 8 Sheet ll of 47 State Department of Highways and Public Transportation Right of Way Division UT1LiTY MANU~L freeways having frontage roads, planned fences should be located at the freeway right-of-way line. Denial of access regarding property adjoining the right-of-way line will not be altered. (g) Longitudinal installations shall be located on uniform alignment as near as practicable to the right-of-way line to provide space for future highway construction and for possible future utility installations. (h) On highways with frontage roads, longitudinal utility installations will be located between the frontage roads and the right-of-way line. Utility lines shall not be placed or remain in the center median, or beneath through traffic roadways, ramps, or connecting roadways (including shoulders). (i) Utility lines crossing the highway should be located at approximate right angles to the highway to the extent feasible and practicable. Reasonable latitude.may be exercised as regards the crossing angle of existing lines which are otherwise qualified to remain in place. (j) The horizontal and vertical location of utility lines should conform with the clear roadside practices of the department, consistent with the clear- ances applicable to all roadside obstacles. (k) In utility installations~ consideration shall be given to state and local requirements. It shall be the utility company's responsibility to determine if other utility lines exist or are planned at the proposed installation area. The utility company should insure that the proposed installation is compatible with existing or proposed utilities. Plate 8 Sheet 12 of 47 State Department of Highways and Public Transportation Right of Way Division UTILITY MANUAL §21.38. Design. (a) The design of any utility installation will be the responsibility of the utility company. An installation within the highway right-of-way must be reviewed and approved by the department with regard to the location and the manner of adjustment. This includes the measures to be taken to preserve the safety and free flow of traffic, structural integrity of the roadway or highway structure, ease of highway maintenance, appearance of the highway, and the integrity of the utility facility. Utility installations on, over or under the right-of-way of the state highway system shall conform with requirements contained herein and/or, as a minimum, the appropriate requirements outlined in the following, whichever is greater: (1) Safety Rules for the Installation and Maintenance of Electric Supply and Communication Lines - National Electric Safety Code. (2) Title 49, C.F.R., Part 192, Transportation of Natural and Other Gas by Pipeline: Minimum Federal Safety Standards and Amendments.

(b) All utility installations will be of durable materials designed for long life expectancy and relatively free from routine servicing or maintenance. In addition to the requirements herein, any existing utility lines to remain in place must be of satisfactory design and condition in the opinion of the district engineer. (c) Special precautions should be taken during utility installations to avoid disturbing existing drainage courses. In addition, soil erosion should be held to a minimum and sediment from the construction site should be kept away from the roadway and drain inlets. (d) Underground utility installations should be backfilled with pervious material and outlets provided for entrapped water. Underdrains shall be provided where necessary. No jetting orpuddling beneath the roadway will be permitted. (el Clearances between underground utilities and storm sewers shall be a minimum of 12 inches if the installation can take place without disturbing the storm sewer installation. Otherwise, the minimum clearance will be 24 inches. (f) On new installations or adjustment of existing utility lines provision for known or planned expansion of the utility facilities n~y be made, all at the sole expense of the utility firm. Any such expansion should be planned so as to minimize hazards and interference with highway traffic at a future date. (g) Manholes shall be limited to those necessary for installation and Plate 8 Sheet 14 of 47 "~tate bepartn~nt of ways and Public Transportation Right of Way Division UTILITY MANUAL maintenance of underground lines. In no case shall they be placed or permitted to remain in the pavement or shoulders of high volume roadways except at those locations on noncontrolled access highways in urban areas where necessary for existing lines which may be permitted to remain in place under existing or proposed roadways. Manholes may remain in place or be installed under traffic lanes of low volume roadways in municipalities provided measures are taken to minimize such installations and to avoid their locations at intersections insofar as possible. Manholes vary as to size and shape depending on the type of utility they serve. Toconserve space their dimensions should be the minimum acceptable by good engineering and safety standards. In general, the only equipment to be installed in manholes located on highway right of way is that which is essential to the normal flow of the utility, such as circuit reclosers, cable splices, relays, valves and regulators. Other equipment such as substation equipment, large transformers, pumps, etc., should be located outside the limits of the highway right-of-Way. Straight line manholes are the only type normally permitted within the right-of-way. The width dimensions should be no larger than is necessary to hold equipment involved and for safety standards to be assured for maintenance personnel. Outside width should not exceed seven feet, with the length to be held to a reasonable minimum. The outside diameter of the manhole chimney at the ground level should not exceed 36 inches. Where proven necessary the outside diameter of the chimney may be up to 50 inches. The top of the roof of the manhole should be five feet below ground level. Where such depth factor is impracticable sufficient data should Plate 8 Sheet 15 of 47 State Department of Highways and Public TransportatiOn Right of Way Division UTILITY MANUAL be submitted to the department for handling as an exception. For width and depth requirements concerning sanitary sewer manholes refer to §21.46 of this title (relating to Sanitary Sewer Lines). All manhole covers shall be installed flush with the ground and/or paven~)nt surface, whichever is applicable. In order to minimize vandalism, manhole covers placed anywhere within state right-of-way must weigh at least 175 pounds. All underground utilities within the highway right-of-way, including manhole rings and covers, must be designed for HS-20 loading. §21.39. Aesthetics. (a) To preserve and protect trees, shrubbery, and other aesthetic features on the highway right-of-way the department may specify the extent and methods of tree removal, tree trimming, or their replacement,and replacement of other aesthetic features, including installation methods of the underground or over- head utility. The district engineer shall use due consideration in establishing the value of trees and other aesthetic features in the proximity of a proposed utility line and any special district requirements justified by the value of the trees and other aesthetic features. (b} The department shall specify prompt replacement of sod, removal of debris, and any other restoration necessary to place the highway in condition equal to that prior to the utility installation. Plate 8 Sheet 16 of 47 State Department of Highways and Public Transportation Right of Way Division UTILITY MANUAL §21.40. Safety. (a) Appropriate measures shall be required in the interests of safety, traffic convenience and access to adjacent property. Appropriate signs, markings and barricades shall be placed by the utility prior to the begi'nning of construction and shall be maintained to properly warn motorists. All traffic control devices shall conform to the TMUTCD. No traffic shall be blocked or stopped at any time without the presence of a vested flagperson to warn and control traffic. (b) Where the cost of installation is the responsibility of the utility firm, the department shall require reimbursement for its cost of measures that the department may take in the interests of traffic safety, or restoration and repairs to the highway, which are made necessary by the utility installation. (c) It is the responsibility of the district engineer to provide inspection as needed to insure that installations are accomplished in a safe manner as approved by the department. §21.41 Site Clean-Up. Roadways adjacent to utility construction sites shall be kept free from debris, roadway construction material, and mud. At the endof every construction day, construction equipment and materials shall be removed as far from the roadway edges as feasible. When utility installation is complete, the right-of-way shall be reshaped to its original condition or better and the area reseeded or resodded to reduce erosion. Should settlement or erosion occur within six months after utility installation, the utility shall reshape, reseed, Plate 8 Sheet 17 of 47 State Department of Highways and Public Transportation Right of Way Division UTILITY MANUAL or resod the area. §21.42. Pipelines - General. (a) Method of protection. {1) Encasemerit. In general, underground utility line crossings shall be encased in the interest of safety, protection of the utility, protection of the highway, and for access to the utility. Encasemerit shall be as specified for each type of line discussed herein. Casing shall consist of a pipe or other separate structure around and outside the carrier line and shall be designed to support the load of the highway and superimposed loads thereon, including that of construction machinery. The strength of the casing shall equal or exceed structural requirements for drainage culverts and it shall be composed of materials of satisfactory durability under conditions to which it may be subjected. (2) Optional for gas or liquid petroleum pipelines. Welded steel pipeline crossings may be installed without encasement provided such pipelines conform with 49 C.F.R., Part 192, Transportation of Natural and Other Gas By Pipeline or Part lg5, Transportation of Liquids By Pipeline as applicable. In accordance thereof such pipelines shall provide: (A) increased wall thickness and/or higher strength steel; (B) greater depth of cover, and (C) adequate markings as specified for each type of line discussed herein. Such pipelines shall also be designed to withstand internal design Plate 8 Sheet 18 of 47 and Public Transportation Right of Way Division UTILITY MANUAL pressures and the superimposed loads of the roadway and traffic, including that bf construction machinery. (b) Manholes. Manholes serving this type of utility should be straight on line installations with a minimum overall width necessary to operate and maintain the enclosed equipment. (c) Depth of underground lines. The depth of underground lines shall be as specified herein for each type of utility. Where placements 8t such depths are impractical or where unusual conditions exist, the department shall specify other protection as may be appropriate in lieu of the depth of bury required for the particular utility line. (d) Methods of installation. (1) Lines placed under any existing roadway shall be installed by boring or tunneling in accordance with appropri ate specifications. Jacking may be used only when approved by the district engineer. When installed by jacking or boring, encasement of the line may be required. (2) For rural (uncurbed) highway cross sections, all borings shall extend beneath all travel lanes plus: (A) 30 feet from all freeway main lanes and other high-speed (exceeding 40 mph) highways except as indicated in subparagraph (B) of this section; (B) 16 feet for high-speed highways with current average daily traffic volumes of 750 vehicles per day or less; (C) 16 feet for ramps; and Plate 8 Sheet 19 of 47 State Department of Highways and Public Transportation Right of Way Division UTILITY MANUAL (D) 10 feet for low-speed (40 mph or less) highways.

(4) All traffic control devices (signs, markings, barricades, etc.) used to warn motorists of the construction activity must conform to the TMUTCD. (5) Where circumstances necessitate the excavation of a bore pit closer to the edge of pavement than set forth above, a guard fence or other approved protective devices will be installed for protection of the traveling public in accordance with current departmental standards. Bore pits shall be located and constructed in such a manner as not to interfere with highway structural footings, safe roadside clearance or traffic operations. If necessary, shoring shall be utilized. (6) The use of explosives for any excavations on theright-of-way incident to utility line installation shall be permitted only when the department has adequate assurance that no damage or hazard will be caused thereby. Such assurance should normally include detailed plans and procedures approved by a person who is qualified and experienced in the use of demolitions. (7) Where longitudinal trenching on the right of way is permitted, back- fill shall be compacted to densities equal to that of the surrounding soil. Trenching across jointed concrete pavement should not be permitted, and in no Plate 8 Sheet 20 of 47 State Department of ways and Public Transportati'on Right of Way Division UTILITY MANUAL instance shall trenching across continuously reinforced concrete pavement be permitted. Exceptians may be made to permit trenching across low ~olume road- ways or urban noncontrolled access roadways where conditions justify. Where trenching across other type pavements is justified, the department shall specify detailed methods for removal and replacement of embankment, base, and surfacing. (el Unsuitable conditions. Conditions which are generally unsuitable or undesirable for pipeline crossings should be avoided. These include locations such as deep cuts; near footings or bridges and retaining walls; across inter- sections at-grade or ramp terminals; at cross drains where flow of water, drift, or stream bedload may be obstructed; within basins or an underpass drained by a pump if pipeline carries a liquid or liquified gas; and in wet or rocky terrain where minimum depth of cover would be difficult to attain. (f) Clearances. Vertical and horizontal clearances between a pipeline and structure or other highway or utility facilities should be sufficient to permit maintenance of the pipeline and the other facilities. (g) Drainage easements. Where it is necessary for pipelines to cross drainage easements, outside of the right-of-way, the same minimum depth of cover shall be maintained as required for crossing ditches inside of the right-of-way. In cases where soil conditions are such that erosion might occur or where it is not feasible to obtain specified depth, it shall be the responsibility of the utility owner to install retards, encasemerit, concrete slabs over the pipe, or take such other measures as needed for safety and to protect the highway and the pipeline. Where grades on the pipelines must be maintained, such as gravity Plate 8 Sheet 21 of 47 State Department of Highways and Public Transportation Right of way Division UTILIIY MANUAL flow sewer .lines, each case will be worked on an individual basis, keeping in mind that the main purpose of the channel is to carry drainage water and that this flow must not be obstructed. §21.43. High PressUre Gas and Liquid Petroleum Lines. (a) Depth of cover. (1) For encased high pressure gas or liquid petroleum lines the minimum total clear depth of cover for ca~ing pipe shall be 30 inches. For that portion of the carrier line outside of the casing pipe, including longitudinal portions, the minimum depth of cover within the highway right-of-way shall be 36 inches. Exceptions may be authorized to permit existing lines to remain in place with a reduction of six inches in the above specified depths of cover. All lines normally shall be a minimum of 18 inches or 1/2 the diameter of the pipe, whichever is greater, beneath the bottom of the pavement structure. Where materials and other conditions justify, such as on existing lines with encasement which are to remain in place, a minimum depth under the pavement structure of 12 inches or 1/2 the diameter of the pipe, whichever is greater, may be permitted. (2) For unencased high pressure gas or liquid petroleum lines the minimum depth of cover shall be 60 inches under the pavement surface or 18 inches under the pavement structure, whichever is greater. Under ditches the minimum depth of cover shall be 48 inches. Exceptions may be authorized to permit a reduction in the specified depths of cover where the pipeline is protected by a reinforced Plate 8 Sheet 22 of 47 State Department of Highways and Public Transportation Right of Way Division UTILITY MANUAL concrete slab. As used herein, depth of lines is the depth to top of carrier (if unencased) or casing (if required). (b) Crossings. (1) Pipeline installations across highways may be encased or unencased. Where encasement is to be employed such encasemerit shall be provided under center medians and from top of backslope to top of backslope for cut sections (or five feet beyond the toe of slope for fill sectigns, or face of curb) of all roadways including side streets, and five feet beyond any overpass or other structure where the line passes under it. Encasemerit may be omitted under center medians where their width is appreciably greater than normal rural standards (76 feet). (2) Where encaseRent is not employed the welded steel carrier pipe shall provide sufficient strlmm~th to withstand theinternal design pressure and the dead and live loads of the pavement structure and traffic. Additional protective measures should include the following: (A) heavier wall thickness and/or higher factor of safety in design; (B) adequate coating and wrapping; (C) cathodic protection; (D) other measures as required by Title 49, CFR, Part 192 or Part 195. (3) The minimum length of the additional protection as set forth above shall be the same as that required by encasemerit. (4) Existing lines under low volume farm-to-market roads and low volume highways may be permitted to remain in place without encaseme~t or extension of Plate 8 Sheet 23 of 47 State Department of Highways and Public Transportation Right of Way Division UTILITY MANUAL encasement if they are protected by a ~einforced concrete slab or equivalent protection or if they are located at a depth of five feet under the pavement surface and not less than four feet under the roadway ditch. If a reinforced concrete slab is to be used, it should meet the following standards: (A) width - three times the diameter of the pipe or five foot minimum, whichever is greater; (B) thickness - six inch minimum; (C) reinforcement - #4 bars @ 12-inch centers each way or equivalent wire mesh; (D) cover- the cushion between the bottom of slab and top of pipe shall be not less than six inches. (c) Vents~ One or ~re vents shall be provided for each casing or series of casings. For casings longer than 150 feet, vents should be provided at both ends. On shorter casings a vent should be located at the high end with a marker placed at the low end. Vents shall be placed at the right-of-way line immedi-ately above the pipeline, situated so as not to interfere with highway maintenance or concealed by vegetation. Ownership of the lines shall be shown on the vents. (d) Markers. The utility company shall place a readily identifiable and suitable marker at each right-of-way line where it is crossed by any high pressure gas or liquid petroleum line except where marked by a vent. Readily identifiable and suitable markers in sufficient number as determed by the DE shall be placed at the right-of-way line for lines installed longitudinally Plate 8 Sheet 24 of 47 State Department of Highways and Public Transportation Right of Way Division UTILITY MANUAL within the SDHPT right of way. (el Above-ground appurtenances. Above-ground appurtenances, except vents, for gas lines shall not be permitted within the highway right-of-way. (f) Exceptions to location requirements. In urban areas, existing longitu- dinal lines which are not under the pavement or shoulder of any roadway or in the center median of a controlled access highway, may be permitted to remain in place provided all other requirements are met. §21.44. Low Pressure Gas Lines. (a) Depth of cover. For low pressure gas lines the minimum depth of cover within the right-of-way and under highway ditches, but outside the pavement structure, including longitudinal portions, shall be 24 inches for either encased or unencased installations. Exceptions may be authorized to permit existing lines to remain in place with a reduction of six inches in the above specified depth. Low pressure gas lines shall be a minimum of 18 inches or 1/2 the diameter of the pipe, whichever is greater, beneath the bottom of the pavement structure. Where materials and other conditions justify, such as on existing lines to remain in place, a minimum depth under the pavement structure of 12 inches or 1/2 the diameter of the pipe, whichever is greater, may be permitted. As used herein, depth of lines is the depth to the top of carrier pipe or casing as applicable. (b) Encasemerit. Low pressure gas lines shall be encased as required for high pressure gas and liquid petroleum lines or they may be placed without Plate 8 Sheet 25 of 47 State Department of Highways and Public Transportation Right of Way DiVision UTILITY MANUAL encasement if they are of welded steelconstruction and are protected from corrosion by adequate and approved cathodic protective measures with specific agreement that the pavement will not be cut for repairs to the pipeline at any time in the future. (c) Vents. Reference should be made to §21.43 of this title (relating to High Pressure Gas and Liquid Petroleum Lines). (d) Markers. The utility company shall place a readily identifiable and suitable marker at each right-of-way line whereit is crossed by a low pressure gas line except where marked by a vent. Readily identifiable and suitable markers in sufficient number as determined by the DE shall also be placed at the right-of-way line for lines installed longitudinally within the SDHPT right of way. (el Plastic lines. Plastic lines may be used provided the internal pressure will not exceed 60 pounds per squareinch, they are encased right-of- way line to right-of-way line on crossings and have at least 30 inches of cover. The maximum size of plastic lines for crossings shall not exceed 24 inches. The maximum size of plastic lines placed longitudinally shall not exceed six inches. Where plastic pipe is installed longitudinally a durable metal wire shall be concurrently installed or other means shall be provided for detection purposes. (f) Above-ground appurtenances. Above-ground appurtenances, except vents, for gas lines shall not be permitted within the highway right-of-way. (g) Exception to location requirements. In urban areas, existing longitu- dinal lines which can be maintained without violating access control and which Plate 8 Sheet 26 of 47 State Department of Highways and Public Transportation Right of Way Division UTILITY MANUAL are not under the pavement or shoulderof any proposed roadway or existing road- way which is scheduled for a major improvement may remain in place provided all other requirements are met and provided further that measures are taken to mini- mize any future need for cutting pavement to make service connections on any high traffic roadway. §21.45. Water Lines. (a) Depth of cover. The depth of cover for water lines shall be the same as stipulated for low pressure gas lines in §21.44 of this title (relating to.Low Pressure Gas Lines). (b) Encasement. Encasement shall be provided ~nder normal width center medians and from center of ditch to center of ditch for cut sections (or five feet behind toe of slope for fill sections or face of curb) of all roadways. Encasement may be omitted under center medians where their width is appreciably greater than normal rural standards (76 feet). Encasemerit under side road entrances may be omitted in consideration of traffic volume, condition of roadway, maintenance responsibility and local practice. Encasemerit under low-traffic roadways may be omitted on existing water lines having an inside diameter of 24 inches or more and on new lines having an inside diameter of 30 inches or ~rem provided all other requirements are met. (c) Plastic lines. Plastic lines may be used provided they have at least 30 inches of cover for both crossing and longitudinal segments. Crossings shall be encased in accordance with §21.42 of this title (relating to Pipelines - Plate 8 Sheet 27 of 47 State Department of Highways and Public Transportation Right of Way Division UTILIIY MANUAL General) and §21.43 of this title (relating to High Pressure Gas and Liquid Petroleum Lines). (d) Nonmetallic pipe detection. Where nonmetallic pipe is installed longitudinally a durable metal wire shall be concurrently installed or other means shall be provided for detectt6n purposes. (el Exceptions to location requirements. Same as stipulated for low pressure gas lines in §21.t4 of this title (relating to Low Pressure Gas Lines). (f) Manholes. The outside diameter of the manhole chimney at the ground level shall not exceed 36 inches. (g) Markers. The utility company shall place a readily identifiable and suitable marker at each right-of-way line where it is crossed by a water line. (h) Irrigation and drainage facilities. Irrigation and drainage facilities installed across any highway right-of-way shall be designed and constructed in accordance with departmental standards for highway culverts or bridges. (i) Ditches and canals. Longitudinal ditches and canals which would closely parallel the highway shall not be permitted nor will any appurtenances be permitted within the clear roadside area which would constitute a hazard to traffic. (j) Location of road. Extreme care shall be exercised in the location of levee roads or ditch rider roads where they intersect the highway so as to avoid establishing any hazards at points of critical sight distance. §21.46. Sanitary Sewer Lines. {a} Depth of cover. The depth of cover for sanitary sewer lines shall be Plate 8 Sheet 28 of 47 State Department of Highways and Public Transportation Right of Way Division UTILITY MANUAL the same as stipulated for low pressure gas lines in §21.44 of this title (relating to Low Pressure Gas Lines). (b) Encasement. Lines to be operated under pressure and those composed of materials not conforming to material or depth of cover requirements herein shall be encased as prescribed for water lines in §21.45 of this title (relating to Water Lines). (c) Materials. New and relocated sewer lines crossing through traffic roadways, ramps, and connecting roadways, ra~s and connecting roadways of controlled access highways, and any other high-traffic roadways shall be ductile iron, with satisfactory joints, or materials and designs which will provide equal or better protection of the integrity of the highway system and resistance to damage from sulfide gases and other corrosive elements to which they may be exposed. New and relocated longitudinal lines and those crossing low-traffic roadways may be of any material which has been proven to be of satisfactory strength and durability in local use, provided all other requirements are met. (d) Nonmetallic pipe, Where nonmetallic pipe is installed longitudinally a durable metal wire shall be concurrently installed or other means shall be pro- vided for detection purposes. (el Manholes. Manholes serving sewer lines up to 12 inches shall have a maximum ID of 4 feet. For any increase in line size greater than 12 inches the manhole ID may be increased a like amount. Manholes for large interceptor sewers should be specially designed, keeping the overall dimensions to a minimum. The outside diameter of the manhole chimney at the ground level shall Plate 8 Sheet 29 of 47 State Department of Highways and Public Transportation Right of Way Division UTILITY MANUAL not exceed three feet. For additionalrequirements refer to §21.38 of this title (relating to Design). (f) Exception for existing lines in urban areas. Except where relocation is necessary to clear existing sewer lines from structures or other highway appurtenances or for other specific reasons, the department may permit existing lines in urban areas to remain in place at any location (except longitudinally under the center median, through traffic lanes or ramps of controlled access highways) provided the line is of satisfactory quality and depth, manholes are adjusted in conformance with general requirements herein, and provisions are made to assure that future service lines requiring violation of access control or disturbing any roadway will be avoided. §21.47. Utility Structures. (a) Interstate highways. Where it would be more economical to carry one or several utility lines across a freeway in a tunnel or on a bridge rather than in separately trenched and encased crossings, consideration should be given to providing a separate structure, specifically for the utility crossing. Such a structure may serve a joint purpose as a utility and pedestrian facility and/or sign support structure. In providing a utility tunnel or bridge, the following should be met: (1) Mutually hazardous transmittants, such as fuels and electric energy, shall be isolated by compartmentalizing or by auxiliary encasement of incompatible carriers. Plate 8 Sheet 30 of 47 State Department of Highways and Public Transportation Right of Way Division UTILITY MANUAL (2) The utility tunnel or utility bridge structure shall conform in design, appearance, location, bury, earthwork, and markings to the culvert and bridge practices of the department. {3) Where a pipeline on or in a utility structure is encased, the casing shall be effectively opened or vented at each end to prevent possible buildup of pressure and to detect leakage of gases or fluids. (4} Where a casing is not provided for a pipeline on or in a utility structure, additional protective measures shall be taken, such as employing a higher factor of safety ih the design, construction, and testing of the pipeline than would normally be required for ca~ed construction. (5) Communication and electric power lines shall be suitably insulated, grounded and preferably carried in protective conduit or pipe from the point of exit from the ground to teentry. The cable should preferably be carried to a manhole located beyond the backwall of the structure. Carrier and casing pipe should be suitably insulated from electric power line attachments. (6) Shut-off valves, preferably automatic, shall be installed in lines at or near ends of utility structures unless segments ofthe lines can be isolated by other sectionalizing devices within a reasonable distance. (7) It is agreed by the utility conl~anies that any maintenance, servicing or repair of the utility lines will be their responsibility. {b) Noninterstate highways. If a utility line (or lines) is on its own easement and it would be more economical to the department to adjust the line (or lines) across a highway by use of a utility tunnel or bridge rather than to Plate 8 Sheet 31 of 47 State Department of Highways and Public Transportation Right of Way Division UTILITY.MANUAL provide separately trenched and cased crossing, consideration should be given to provision of such a structure. Where the utility line (or lines) is on a public right-of-way by sufferance and the adjustment of the utility is the sole responsibility of the private or public utility company, the department may permit the provision of a utility structure without cost to the department provided the conditions outlined in subsection (a) of this section and all other pertinent requirements are met. If a structure is to serve as a joint utility-pedestrian crossing or a joint utility-sign support structure, the department will participate in the same to the extent necessary for accommodation of pedestrians and/or highway signs only. §21.48. Traffic Structures. (a) The attachment of utility lines to bridges and separation structures is discouraged, since the proliferation of such lines and their maintenance constitutes a hazard to traffic as well as complicating the widening or repair of such structures. Attaching utility lines to a highway structure can materially affect the structure, the safe operation of traffic, the efficiency of maintenance, and the overall appearance. Therefore, when it is feasible and reasonable to locate utility lines elsewhere, attachment to bridge structures will not be allowed. . (b) Where other arrangements for a utility line to span an obstruction are not feasible, the department may consider the attachment of such line to a bridge structure. Any exceptions which are permitted shall be handled in Plate 8 Sheet 32 of 47 State Department of Highways and Public Transportation Right of Way Division UTILITY MANUAL accordance with the conditions set forth in §21.47 of this title (relating to Utility Structures) and other pertinent requirements contained herein. Each such attachment will be considered on an individual basis and permission to attach will not be considered as establishing a precedent for granting ~f subsequent requests for attachment. The following guides are established for attachment of utilities to bridges. (1) When it is impractical to carry a self-supporting con~nunication line across a stream or other obstruction, department policy is to permit the attachment of the line to its bridges. On existing bridges the state generally requires that the line be enclosed in conduits.and so located on structures as not to interfere with stream flow, traffic, or routine maintenance operations. When a request is made prior to construction of a bridge, suitable conduits will be provided in the structure if the utility company bears the cost of all additional work and materials involved. (A) When a line is attached to a bridge, the state will enter into a special agreement or contract with the utility company. (B) In urban areas where it is the state's responsibility to provide for the adjustment of telephone lines or telephone conduits to accommodate the construction of a highway, and the adjustment provides for the placement of telephone conduits in a highway grade separation structure, the department.will allow a reasonable number o~ spare telephone conduits in the Structure provided the spares are placed at the time of construction and the telephone company bears the cost of these spare conduits. Plate 8 Sheet 33 of 47 State Department of Highways and Public Transportation Right of Way Division UTILITY MANUAL (C) Where the construction of.a highway makes it necessary to relocate telephone conduits and the proper adjustment, in the opinion of the department, provides for the placement of telephone conduits in the highway grade separation structure, the department will permit the telephone company to install replacement telephone conduits and a reasonable number of spares in the structure provided such conduits are placed at the time of construction and provided the company bears any extra structure cost occasioned by the presence of the telephone conduits. (2) No gas or~liquid fuel lines~shall be attached to a bridge or grade separation structure without the specific approval of the state engineer- director. {3) Power lines are not permitted on bridges under any condition with the exception of low-voltage distribution lines where the cost of independent facilities to carry these lines would be prohibitive. (4) When a municipality or utility company requests permission to attach a pipeline to a proposed bridge prior to construction, and the added load is sufficient to require an increase in the strength of the structure, or use of more costly materials or type of construction, the utility owner is required to pay for the increase in cost. (5) When a utility company requests permission to attach a pipeline to an existing bridge, sufficient information should be furnished to allow a stress analysis to determine the effect of the added load on the structure. Other details of the proposed attachment as they affect safety and maintenance should Plate 8 Sheet 34 of 47 State Department of Highways and Public Transportation Right of Way Division UTILITY MANUAL also be presented. If the bridge structure is not of adequate strength to carry the increased weight or forces with safety, permission will not be granted. (6) All requests for attachments to bridges or structures should originate with the utility company by its making application to the appropriate district engineer. (A} For attachments to structures within active projects, requests for attachment along with the district engineer's recommendation should be forwarded to the bridge engineer for review and concurrence. Adequate Justification, including details and an estimate for an independent utility crossing, should accompany the submission. If the attachment is allowed, the bridge engineer will prepare a suitable agreement and forward it to the district for handling with the utility company for execution. Modification of the structural details to accommodate the utility and the responsibility of cost thereof will be developed by the bridge engineer. Where applicable, the bridge engineer will coordinate the submission with the right of way engineer. In addition, use and occupany agreement forms shall be required as cited in §21.52 (relating to Forms - General) and §21.53 (relating to Use and Occupany Agreement Forms). (B) For attachments to structures not within active projects, requests for attachment along with the district engineer's recommendation should be forwarded to the chief engineer of maintenance and operations for review and concurrence. Adequate justification, including details and an estimate for an independent utility crossing, should accompany the submission. The proposal will then be forwarded to the bridge engineer for review and determination of Plate 8 Sheet 35 of 47 State Department of Highways and Public Transportation Right of Way Division UTILITY MANUAL the effect of the proposed attachment on the existing structure. If the attachment is allowed, the'bridge engineer will prepare a suitable agreement and forward it to the district for h&ndling with the utility company for execution. In addition, notice forms shall be required as cited in §21.52 (relating to Forms - General) and §21.54 (relating to Notice Forms). §21.49. Overhead Power and Communication Lines. (a} Type of construction. Longitudinal lines on the right-of-way shall be limited to single pole construction. Transverse lines should desirably be limited to single pole construction; however, where an existing or. proposed utility is supported by "H" frames, towers, etc., the same type structures may be utilized for the crossing provided all other requirements herein are met. (b} Vertical clearance. Except as stated herein, the minimum vertical clearance above the highway shall be not less than 22 feet for power lines, and 18 feet for communication and cable television lines. These clearances may be greater, as required by the National Electric Safety Code and governing laws. (c) Location. (1) In rural areas and at uncurbed sections in urban areas, poles supporting longitudinal lines shall be located from one to three feet from the right-of-way edge, except that at the option of the department this distance may be varied at short breaks in the right-of-way line. Guy wires placed within the right-of-way shall be held to a minimum and should normally be in line with'the pole line; however, other locations may be permitted, but in no case shall the Plate 8 Sheet 36 of 47 State' Department of Highways and Public Transportation Right of Way Division UTILITY MANUAL guy wires or poles be located closer than the minimum allowed for the specific design values for the highway class and volumes as shown in Appendix A of this section. At curbed sections, in urban areas, poles shall be located as far as practical behind the outer curbs and preferably adjacent to the right-of-way line. Steel poles with bases greater than 36 inches shall not be placed within the right of way except in extreme hardship situations and if sufficient space remains for other utilities. Exceptions may be considered where ample right of way exists and the poles are to be placed outside of the clear zone or in accordance with the minimum allowed for the specific design value for the highway class and volume, whichever is greater. (2) At crossings, no poles will be permitted in the center median of any highway. Poles will only be permitted in outer separations or more than three feet inside the right of way where the right of way is of such extreme width (over 300 feet) that the cost of spanning it is excessive and where poles can be located in accordance with the intent and provisions of paragraph (1) of this subsection. (3) As a general rule, overhead power, communication and cable television line crossings, at bridges or grade separation structures should be avoided, if possible. If rerouting the line completely around the structure and approaches is not economically feasible, a minimum horizontal distance of 150 feet or a minimum vertical clearance of 30 feet should be provided to insure adequate safety for construction and maintenance operations. (d) Horizontal Clearances. The following Appendix A indicates the design values for horizontal clearances.

Plate 8 Sheet 38 of 47 State Department of Highways and Public Transportation Right of Way Division UTILITY MANUAL §21.50. Underground Power Lines. (a) Longitudinal. All underground power lines placed within SDHPT right- of-way may be directly buried at depths according to the voltages of power lines as follows: VOLTAGE MINIMUM DEPTH OF BURY 22,000 or less 30 inches 22,001 to 40,000 36 inches 40,001 and greater 42 inches These depths are'currently required by the Nat!onal Electric Safety Code. Amendments to the code may require greater depths in the future. (b} Crossings. Power lines shall be encased (placed in conduit).and buried a minimum of 36 inches under roadway ditches, and 60 inches below the pavement surface. (c) Encasement. Encasement shall be provided under center medians and from top of backslope to top of backslope for cut sections (or five feet beyond the toe of slope for fill sections, or face of curb) of all roadways including side streets and beneath and five feet beyond any overpass or other structure where the line passes under it. Encasement may be omitted under center medians where their width is appreciably greater than normal rural standards (76 feet), Existing lines under low volume farm-to-market roads and low volume highways may be permitted to remain in place without encasement or extension of encasement if they are protected by a reinforced concrete slab or equivalent protection or if they are located at a depth of six feet under the pavement surface and not les~ than four feet under the roadway ditch. If a reinforced concrete slab is to be Plate 8 Sheet 39 of 47 State Department of Highways and Public Transportation Right of Way Division UTILITY MANUAL used, it should meet the following standards: (1) width - five foot minimum; (2) thickness - six inch'minimum; (3) reinforcement - #4 bars at 12 inch centers each way or equivalent wire mesh; (4) cover - the cushion between the bottom of slab and top of cable shall be not less than six inches. (d) Markers. Readily identifiable and suitable markers in sufficient number as determined by the DE shall be placedat the right-of-way line for lines installed longitudinally within the SDHPT right of way. Wherean underground power line crosses, a marker shall be placed at each right-of-way line. (el Location. Longitudinal underground power lines may be placed by plow- ing or open trench method and shall be located as set forth in §21.37 of this title (relating to Location). (f) Above-ground appurtenances. Above-ground utility appurtenances installed as a part of an underground power line shall be located at or near the right-of-way line, well outside the highway maintenance operation area. (g) Manholes. Requirements for manholes shall be the same as cited in §21.38 of this title (relating to Design). §21.51. Underground Communication Lines. (a) Longitudinal. The minimum depth of cover for cable television and Plate 8 Sheet 40 of 47 State Department of Highways and Public Transportation Right of Way Division UTILITY MANUAL copper cable communications lines shall be 24 inches. The minimum depth of cover for a fiber optic facility shall be 42 inches; provided, however, that said minimum depth of cover may be not less than 36 inches if the owner/operator of a fiber optic facility waives damages and fully indemnifies the department in a form acceptable to the department. (b) Crossings. Lines should be located at approximate right angles to the highway to the extent feasible and practicable. Reasonable latitude may be exercised as regards the crossing angle of existing lines which are otherwise qualified to remain in place. (1) The minimum depth of cover for cable television and copper cable communication lines shall be 24 inches under ditches or 18 inches beneath the bottom of the pavement structure, whichever is greater. (2) The top of a fiber optic facility shall be placed a minimum of 42 inches below the ditch grade or 60 inches below tha top of the pavement structure, whichever is greater; provided, however, that said minimum depth of cover below the ditch grade may be not less than 36 inches or 60 inches below the top of the pavement structure whichever is greater if the owner/operator waives damages and fully indemnifies the department in a form acceptable to the department. (3) Lines crossing highways do not require encasement except where in the judgment of the district engineer such encasement is necessary for the protec- tion of the highway facility. Consideration should be given.to encasement or other suitable protection for any communication facilities: Plate 8 Sheet 41 of 47 State Department of Highways and Public Transportation Right of Way Division UTILITY MANUAL (A) with less than minimum bury~ (B) near footings of bridges or other highway structures; or (C) near other locations where there may be hazards. (4) When the installation of the line is to be accomplished by boring a hole the same or about the same diameter as the line and pulling it through, then encasement is not necessary. Where such conditions cannot be met, encase- ment should be provided. The annular void between the drilled hole and the line or casing should be filled with a satisfactory material to prevent settlement of any part of the highway facility over the line or casing. (5) Encasement may be of metallic or nonmetallic material, Such encase- merit material shall be designed to support the load of the highway and superim- posed loads thereon, including that of construction machinery. The strength of the encasement material shall equal or exceed structural requirements for drain- age culverts and it shall be composed of materials of satisfactory durability under conditions to which it may be subjected. The length of any encasement shall be provided under center medians and from top of backslope to top of backslope for cut sections (or five feet beyond the toe of slope for fill sections, or face of curb) of all roadways including side streets. Encasement may be omitted under center medians where their width is appreciably greater than normal rural standards (76 feet). Where encasemerit is not installed, specific agreement should be reached with the utility company that the pavement will not be cut for repairs any time in the future. (c) Markers. The utility company shall place a readily identifiable and Plate 8 Sheet 42 of ~7 State Department of Highways and Public Transportation Right of Way Division UTILITY MANUAL suitable marker at each right-of-way line where it is crossed by an underground communication line. Readily identifiable and suitable markers in sufficient number as determined by the DE shall be placed at the right-of-way line for lines installed longitudinally within the SDHPT right-of-way. Where fiber optic lines are installed without a metal sheath or a metal casing, a durable metal wire shall be concurrently installed or other means shall be provided for detection purposes. (d) Placement. Lines may be placed by plowing or open trench method and shall be located on uniform alignment as near as practical to the right-of-way line to provide space for possible future highway construction and for pp~si.ble future utility installations.
