(A) The applicant shall submit with the application the following:
(1) Drawings or sketches showing in detail the location of the proposed facility or operation with respect to existing and planned street improvement, the traveled way, the right-of-way lines, and, where applicable, the access control lines and approved access points;
(2) The details of the attachment method if facilities are to be attached to a street structure; and
(3) Pressure pipelines data, if applicable as set forth below:
(a) Design pressure of pipe;
(b) Normal operating pressure; and
(c) Maximum operating pressure.
(B) The applicant’s completed facility shall be in substantial conformance with the information required by division (A) above, unless permission is obtained from the Public Works Director or his or her designee to modify during installation. When a modification is approved, the applicant shall furnish the Public Works Director or his or her designee four sets of “as constructed” drawings or sketches.
(C) All work in connection with the facility authorized by the permit shall be done in a neat and workmanlike manner to the satisfaction of the Public Works Director or his or her designee, and construction shall conform to the rules of the State Public Utility Commissioner, the State Board of Health, or other governmental agencies having regulatory authority over the facility. In the event the above agencies do not prescribe standards which provide the degree of protection substantially equal to the following industry codes, then the appropriate industry codes shall apply as found in the American Society of Mechanical Engineers (ASME) codes and standards.
(D) Corrugated metal pipe and concrete pipe used as a conduit or casing pipe or a gravity flow carrier pipe shall, as a minimum, conform to requirements of the current issue of State of Oregon, Standard Specifications for Highway Construction. Smooth iron or steel pipe used as a conduit or casing pipe shall be the standard type used for pressure pipe.
(E) No trench shall be excavated with a top width in excess of 18 inches more than the outside diameter of the pipe, conduit, or cable to be installed unless permission is obtained from the Public Works Director or his or her designee.
(F) The backfilling of all trenches and tunnels must be accomplished immediately after the facility authorized by the permit has been placed therein and must be well tamped and fully compacted so as to allow the least possible amount of subsequent settlement.
(G) All debris, refuse, and waste of all kinds which may have accumulated upon the street right-of-way by reason of the operations of the applicant shall be removed immediately upon completion of the said operations, and the street right-of-way restored to the condition it was prior to construction.
(H) Unless permission is obtained from the Public Works Director or his or her designee to open cut for pipe line or conduit which crosses under the surfaced portion of the street and shoulders, street or street connections, street approaches, or driveways, the permit holder shall tunnel, jack, or drive under the surface in accordance with the following provisions.
(1) Trenching shall be no nearer the toe of the fill slope in fill sections or the point where the outer edges of the surfacing meets the subgrade in other sections than specified in the special provisions.
(2) Tunneling shall be by an approved method which supports the surrounding materials so as to prevent caving or settlement. Areas around the installed pipe or conduit shall be backfilled with moist sand, granular material, or cement grout filling all voids and packed in place with mechanical tampers or other approved devices. Lagging, bulkheading, and timbering shall be removed as the backfilling progresses.
(3) Jacking, driving, or boring shall be by approved means which will hold disturbances of surrounding material to a minimum. Sluicing and jetting is not permitted. Voids or displacement outside the outside perimeter of the pipe, conduit, or cable where greater than 0.1 foot, shall be filled with sand or cement grout packed in place.
(I) When permission is granted to open cut the surfaced portion of the street, the following provisions shall be followed.
(1) Trench edges in paved areas shall be sawn or cut to neat lines by methods satisfactory to the Public Works Director or his or her designee to a depth sufficient to permit removal of pavement without damage to pavement to be left in place. Pavement within the cutting limits, together with all other excavated material, shall be removed and disposed of outside street right-of-way.
(2) No more than half of the traveled way shall be trenched at one time. The opened half shall be completely backfilled before opening the other half.
(3) Closure of intersecting streets, street approaches, or other access points will not be permitted. Upon trenching across such facilities, steel running plates, planks, or other satisfactory methods shall be used to provide for traffic to enter or leave the street or adjacent property.
(4) No more than 300 feet of trench longitudinally along the street shall be open at one time and no trench shall be left in open condition overnight.
(5) Immediately after a facility authorized by a permit has been placed in the trench, the trench shall be backfilled with compacted granular material, commonly designated as previous material, which cannot be ribboned out between the finger and thumb and which is free from humus, organic matter, vegetable matter, frozen material, clods, sticks, and debris, and contains no stones having a dimension greater than three inches. Said granular material shall be placed to an elevation which will allow placing the following foundation material and wearing surface.
(a) Where original surface was asphalt concrete or bituminous treatment or mix:
1. Wearing surface: asphalt concrete placed to a compacted thickness of four inches or the thickness of the removed pavement, whichever is greater; and
2. Foundation material either 1-0 inch or 3/4 - 0 inch aggregate placed to a compacted thickness of four inches or the thickness of the removed stone base, whichever is greater.
(b) Where original surface was crushed rock or gravel, wearing surface, and foundation material - either 1-0 inch or 3/4 - 0 inch aggregate placed to a total compacted thickness of four inches or the thickness of the removed stone base and wearing surface, whichever is greater.
(c) All materials in divisions (I)(5)(a) and (I)(5)(b) above and their placement shall conform to the requirements of the current Oregon State Highway Standard Specifications for Highway Construction.
(6) For a period of one year following the patching of the paved surface, the applicant shall be responsible for the condition of pavement patches, and, during that time, shall, upon request of the Public Works Director or his or her designee, repair to the Public Works Director’s or his or her designee’s satisfaction any patches which become settled, cracked, broken, or otherwise faulty.
(J) Unless permission is obtained from the Public Works Director or his or her designee, direct burial of cable placed by the ploughing method shall be limited to areas outside the surfaced portion of the street.
(K) Standard warning signs for buried power or communications cable and for pipelines carrying gas or flammable liquids shall be placed at each crossing under the street and at intervals along longitudinal installations as required by current PUC order, or as specified by the Public Works Director or his or her designee, such as:
(1) Signs shall be offset as near the right-of-way line as practical; and
(2) Signs for installations located within the streetbed may be placed behind existing guard rail.
(L) Pole line locations over the street shall have a minimum height of the lowest wire at 20 feet; locations parallel and not on the traveled portion, the minimum height of the lowest wire shall be 18 feet. Poles shall be located not less than 12 feet from the edge of pavement on paved-surfaced streets, or not less than eight feet from the shoulder on gravel-surfaced streets. Wherever possible, poles shall be located along the tangent section of streets and on the short curve radius side of curves. Poles to be located on the long radius side of curves will require additional approval by the Public Works Director or his or her designee and will be subject to special conditions.
(M) Pedestals installed as part of a buried cable installation are to be located one foot from the right-of-way line unless permission is obtained from the Public Works Director or his or her designee to locate elsewhere. In no case shall the pedestals be located within the street maintenance operating area, including mowing operations, or nearer the pavement edge than any official highway sign in the same general location.
(N) The buried cable or pipe depth shown on the permit form represents the distance from the top of the surface or ground line to the top of the cable or pipe.
(O) It is strictly forbidden to spray herbicides and cut or trim treas or shrubs growing on the street right-of-way unless written permission has been obtained from the city.
