8.10.170 Bingham Junction and Jordan Bluffs—Clean utility corridors.
Except as provided in Section 8.10.070, the cover and materials management provisions of this chapter in Sections 8.10.060, 8.10.100, 8.10.130, and 8.10.150 do not apply to clean utility corridors installed, approved, and maintained in accordance with this section. Clean utility corridors shall include those utility corridors located within the boundaries of Bingham Junction or Jordan Bluffs and identified in Figure N that meet the requirements in this section. Figure N shall be a compilation of as-built drawings (as amended from time to time and adopted by reference) identifying the location of installed clean utility corridors mapped using GPS coordinates. Said information shall also be included as a layer on the city’s GIS-based utility maps. In order to qualify as a clean utility corridor, the corridor must meet the following requirements:
A. The utility corridor location and utilities (wet or dry) to be located in the corridor must be approved by the city and incorporated into Figure N;
B. The utility corridor is to be excavated to meet engineering requirements with excavated materials to meet materials management provisions of this chapter, including without limitation the requirement to place a geotextile demarcation material (or equivalent) to mark the bottom of the clean utility corridor excavation;
C. The vertical edges of the clean utility corridor will be marked by using brightly colored geotextile material (or equivalent);
D. All bedding and backfill materials put back into the trench must meet the definition of clean fill in Section 8.10.030(H), including a requirement to have a clean fill barrier of at least twenty-four inches in single-family use areas; and
E. Any subsequent maintenance and/or repairs to utilities within clean corridors will be conducted to meet these requirements, that is:
1. Materials removed from the clean utility corridor will be managed as clean fill;
2. Materials placed back into the clean utility corridor must qualify as clean fill;
3. Vertical and horizontal demarcation materials will be preserved and replaced with new material as necessary; and
4. Reasonable care will be taken to ensure that cross-contamination will not occur along vertical clean utility corridor wall boundaries. (Ord. 5/6/2008O-4)
