Chapter 12.08 SIDE SEWER INSTALLATION

Where it is necessary, in order to make a connection to a public sewer to excavate in any public road, street, avenue, alley or other public right-of-way, or utility easement, such excavation shall be restored promptly and expeditiously following inspection and approval of the new line. The requirements for the excavation and restoration shall be as set forth in KMC 12.08.015 through 12.08.025. (Ord. 930 § 2, 1980)

12.08.015 Excavation through bituminous or asphaltic concrete surfaces.

(a) No excavation through bituminous or asphaltic concrete surfaces shall be commenced until a permit therefor has been obtained from the city, which permit shall be subject to the requirements of KMC 12.08.035 through 12.08.070. Such permit shall specify and set forth the time of opening, limitations on disruption of normal traffic flow or other necessary public access, time of closing of excavation, and any other pertinent conditions, regulations and/or restrictions regarding performance of the work.

(b) Surfacing shall be cut completely through before removal. Surfacing shall be cut a minimum of one foot wider than the sub-base trench excavation. Edges of the existing surfacing shall be trimmed to a neat line. Where excavations are made for the full width of the surfaced roadway, existing surfacing shall be cut a sufficient width to permit the use of a 10-ton roller or equivalent for compaction of the new asphalt concrete surfacing.

(c) Backfilling shall be with select material. Native material may be used for backfill only when specifically authorized by the DPW.

(d) Backfill material shall be installed in six inch by the modified AASHTO method.

(e) The top six-inch lift of backfill material shall be crushed base course as approved by the DPW.

(f) All asphaltic concrete or bituminous surfaces shall be restored by the application of two courses of two inches each of Class B asphaltic concrete. Asphalt paint shall be applied to the joints of existing surfacing prior to application of new surface material. Where excavations are made the full width of the surfaced roadway, a minimum 10-ton roller or equivalent shall be used for compaction of the new asphalt surfacing.

(g) If final restoration of surfacing is delayed for weather or other reasons, a temporary repair shall be made by the installation of cold-mix asphalt. Any delay in the time specified for completion in the permit shall be approved in advance by the DPW. (Ord. 930 § 2, 1980)

12.08.020 Excavation through concrete paving and concrete base with asphalt surfacing.

(a) No excavation through rough concrete paving and concrete base with asphalt surfacing shall be commenced until a permit therefor has been obtained from the city, which permit shall be subject to the requirements of KMC 12.08.035 through 12.08.070. Such permit shall specify and set forth the time of opening, limitations on disruption of normal traffic flow or other necessary public access, time of closing of excavation, and any other pertinent conditions, regulations, and/or restrictions.

(b) Line drilling with rotary drills or saw cut shall be required along the trench or cut outline. Six-inch spacing center-to-center shall be required for drill holes in pavement nine inches or less in depth. Drill holes shall be perpendicular to the surface. Drill holes parallel to a longitudinal joint will not be required if the panel removed extends to the joint itself. The saw cut shall be to a minimum depth of three inches or one-half the depth of the pavement, whichever is greater.

(c) Backfilling shall be with select material. Native material shall be used for backfill only when specifically authorized by the DPW.

(d) Backfill material shall be installed in six-inch lifts and each lift shall be mechanically tamped and compacted to 95 percent of maximum density as measured by the modified AASHTO method.

(e) The top four-inch lift or backfill material shall be crushed base course as approved by the DPW.

(f) Concrete surfacing or concrete base shall be Class A cement concrete pavement.

(g) Asphaltic concrete surfacing shall be Class B asphaltic concrete.

(h) If final restoration of surfacing is delayed for weather or other reasons, a temporary repair shall be made by the installation of cold-mix asphalt. Any delay in the time specified for completion shall be approved in advance by the DPW. (Ord. 930 § 2, 1980)

12.08.025 Backfill through unsurfaced right-of-way areas.

Trench backfill through right-of-way areas other than surfaced areas shall be native material except where native material shall be deemed unsuitable by the DPW. Backfill through unsurfaced right-of-way areas shall be compacted to 90 percent of maximum theoretical density. (Ord. 930 § 2, 1980)

All work shall be conducted with due regard for the safety and convenience of the public. Open trenches shall be provided with barricades that can be seen at a reasonable distance, and shall be adequately lighted at night. Lighted signs for detours and construction in progress shall be provided. All conditions of the construction permit shall be strictly observed; however, following or failure to follow such conditions or requirements shall in no way impose any responsibility or liability on the city and shall not relieve the owner or the person doing the construction of his responsibility or liability.
