(Ord. 1454 §22, 2002).

11.32.230 Back-filling.

Back-filling in any street opened or excavated pursuant to an excavation permit issued hereunder shall be compacted to a degree equivalent to that of the undisturbed ground in which the trench was dug. Compacting shall be done in such manner as required by applicable city standards or, in the absence thereof, such manner as may be required by the soil in question and sound engineering practices generally recognized in the construction industry. When water is taken from a hydrant, the permittee shall assign one person to operate the hydrant and shall make certain that said person has been instructed in the operation of the hydrant. The public works department shall likewise be notified at both the beginning and end of the job so that the condition of the fire hydrants can be checked on both occasions. Any damage done to the hydrant during the excavation shall be the responsibility of the permittee. Water shall be paid for by the permittee on the terms agreed upon with the public works department.

In the absence of other applicable standards, the following shall apply:

(a) Back-filling by water settling. When back-filling is to be done by water settling and before any compacting of the trenches is attempted, the permittee shall cause the loose material to be wetted by forcing a head of water of not less than thirty feet in height, down into the soft material so that the end of the pipe is not more than three feet above the bottom of the excavation. The permittee shall allow the water to run until the material is saturated as indicated by the water rising and running out on the surface of the ground around the pipe. After each hole has been saturated, the jet pipe shall be moved along the trench line a distance of approximately four or five feet, but in no case more than eight feet, and the process repeated for the entire length of the back-fill trench. All work shall be done in such a manner as to obtain a relative compaction throughout the entire depth of the back-fill of not less than existing adjacent to the excavation.

(b) Dry back-filling. Back-filling up to the first eighteen inches above the top of the utility pipes or similar installations shall be done with thin layers. Each layer is to be tamped by manual or mechanical means. Layers that are hand tamped shall not exceed four inches in thickness. Layers that are power tamped shall not exceed five inches in thickness. The same requirements shall apply to the remainder of the back-filling if tamping is the method used for back-filling. Back-filling of all pipes of over twenty-four inches in diameter shall be carried up to the spring line of the pipe in three-inch layers, with each layer moistened and thoroughly tamped with suitable mechanical equipment. The back-fill around all pipes twenty-four inches or less in diameter shall be flooded or tamped as specified above to a depth of eighteen inches above the top of the pipe before any additional backfilling is placed thereon.

(c) Back-fill material. Whenever any excavation for the laying of pipe is made through rock, the pipe shall be laid six inches above the rook bottom of the trench and the space under, around, and six inches above the pipe shall be back-filled with clean river sand, non-corrosive soil or one-quarter inch minus gravel. Broken pavement, large stones, and debris shall not be used in the back-fill.

(d) Back-filling at the surface. Back-filling shall be completed by placing the back-fill material well up over the top of the trench. For dry back-filling, the material shall be compacted with a roller of an approved type or with the rear of a truck carrying at least five tons until the surface is unyielding. Care shall be taken that material being compacted has proper moisture content for maximum compactibility. The surface shall then be graded as required.

Any deviation from the methods set forth above shall have prior written approval of the director of public works. (Ord. 1454 §23, 2002).

11.32.240 Restoration of surface.

The permittee shall restore the surface of all streets, broken into or damaged as a result of the excavation work, to its original condition in accordance with the specifications of the director of public works. The permittee may be required to place a temporary surface over openings made in paved traffic lanes. Except when the pavement is to be replaced before the opening of the cut to traffic, the fill above the bottom of the paving slab shall be made with suitable material well tamped into place and this fill shall be topped with a minimum of at least one inch of bituminous mixture which is suitable to maintain the opening in good condition until permanent restoration can be made. The crown of the temporary restoration shall not exceed one inch above the adjoining pavement. The permittee shall exercise special care in making such temporary restorations and must maintain such restorations in safe traveling condition until such time as permanent restorations are made. The asphalt which is used shall be in accordance with the specifications of the director of public works.

If in the judgment of the director of public works it is not expedient to replace the pavement over any cut or excavation made in the street upon completion of the work allowed under such permit by reason of the looseness of the earth or weather conditions, the director of public works may direct the permittee to lay a temporary pavement of wood or other suitable material designated by him over such cut or excavation to remain until such time as the repair of the original pavement may be properly made.

Permanent restoration of the street shall be made by the permittee in strict accordance with the specifications prescribed by the director of public works to restore the street to its original and proper condition, or as near as may be.

Acceptance or approval of any excavation work by the director of public works shall not prevent the city from asserting a claim against the permittee and its surety under the surety bond required hereunder for incomplete or defective work if discovered within twenty-four months from the completion of the excavation work. The director of public works' presence during the performance of any excavation work shall not relieve the permittee of its responsibilities hereunder. (Ord. 1454 §24, 2002).

11.32.250 City's right to restore surface.

If the permittee shall have failed to restore the surface of the street to its original and proper condition upon the expiration of the time fixed by such permit or fails to prosecute the work in accordance with the requirements of this chapter or shall otherwise have failed to complete the excavation work covered by such permit, the director of public works, if he deems it advisable, shall have the right to do all work and things necessary to restore the street and to complete the excavation work. The permittee shall be liable for the actual cost thereof and twenty-five percent of such cost in addition for general overhead and administrative expenses. The city shall have a cause of action for all fees, expenses and amounts paid out and due it for such work and the city shall also enforce its rights under the permittee's surety bond provided pursuant to this chapter.

It shall be the duty of the permittee to guarantee and maintain the site of the excavation work in the same condition it was prior to the excavation for two years after restoring it to its original condition. (Ord. 1454 §25, 2002).

11.32.260 Trenches in pipe laying.

Except by special permission from the director of public works, no trench shall be excavated more than two hundred and fifty feet in advance of pipe laying nor left unfilled more than five hundred feet where pipe has been laid. The length of the trench that may be opened at any one time shall not be greater than the length of pipe and the necessary accessories which are available at the site ready to be put in place. Trenches shall be braced and sheathed according to generally accepted safety standards for construction work. No bracing, lagging, sheathing or other materials utilized in such bracing or sheathing shall be left in any trench at the time of its filling. (Ord. 1454 §26, 2002).

11.32.270 Prompt completion of work.
