in writing by the Utility Permit and Inspections Supervisor. Structures and facilities shall not <br /> be located in the planting strip between the curb and sidewalk where they could conflict with <br /> existing or future street trees. Facilities such as transformers, junction boxes, water meters, <br /> and fire hydrants may be placed in the planting strip when necessary so long as their location <br /> allows for street tree planting requirements as detailed in R-7.280. Utilities are required to <br /> avoid conflicts with stormwater-related conveyance and treatment facilities. <br /> 4. No portion of a utility trench within a street may be located closer than one foot parallel to <br /> the face of the gutter. Utility trenches shall not be located closer than one foot parallel to the <br /> back of the curb. <br /> 5. Whenever pavement removal within public streets would cause the pavement to be cut <br /> within three feet of an existing edge, curb, score, joint, or crack, the existing pavement shall <br /> be removed to that edge, curb, score, joint, or crack. Undermined street sections shall be <br /> removed. <br /> 6. Minimum width of pavement cuts shall be three (3) feet in portland cement concrete streets, <br /> alleys, and driveways; and a "T" trench in asphalt concrete streets which shall be computed <br /> as follows: Surface Width of Trench (including sloughing) + One Foot (six inches each <br /> side). An acceptable alternative to using the "T" trench is through the performance of <br /> compaction testing by an independent testing lab. If this alternative is selected, frequency <br /> of the compaction testing shall be as is currently specified by the City on City contract <br /> projects. Alternate trenching and backfill methods resulting in pavement cuts which differ <br /> from these standards may be submitted for consideration on a case-by-case basis. <br /> Pavement cuts for vacuum type excavation shall be no greater than 24" ~t-ide for square cuts <br /> and no greater than 12" in diameter for round core cuts. Pavement restoration for core cuts <br /> shall be 24" square. Backfill for vacuum type excavation within or adjacent to paved <br /> surfaces shall be controlled density fill (CDF). Surface restoration for ~~acuum excavation <br /> shall conform to requirements of section 3.B.1 for concrete surfaces and 3.B.2 for asphalt <br /> surfaces. Monitoring wells within or adjacent to paved surfaces shall be backfilled with <br /> CDF. <br /> 7. Cutting of existing pavements shall be performed with a rotary saw. The alignment of the <br /> cutting shall be straight and the cutting depth shall be to a minimum of 60% of the existing <br /> pavements depth. <br /> Minor maintenance of existing facilities requiring small amounts of asphalt concrete <br /> pavement cutting (less than 15 linear feet around the perimeter of the excavation} may be <br /> performed using a clay spade. <br /> 8. Unless otherwise approved, pavement cuts shall be made parallel or perpendicular to the <br /> centerline of the public way. <br /> Utility & R/W Permit Policy <br /> <br /> Exhibit A - 24 r:\adminord\rule~ 00rowrlexa.wpd(04/13/00) <br /> <br />
