26. The wire size for conductors carrying current to photo -electric control (PEC) shall -be <br />TYPE OF multi -conductor No. 14 AWG <br />27. Wiring for AWG #8 and larger shall be XHHW, copper, stranded, single conductor. <br />Wiring for AWG #10, and wiring where any part of the run is direct buried, shall be <br />Type OF cable. <br />28. Multi -phase conductors, and multi -circuited in one conduit conductors, shall be <br />factory supplied color -coded wire. Wire color shall be consistent from service <br />connection to last light on circuit. Switching of color code in mid -circuit will not be <br />allowed. <br />29. Underground splicing shall be kept to a minimum. <br />30.

Street light poles shall not be permitted in sidewalk areas unless right-of-way <br />constraints prevent other options and an exception is approved by City staff. If poles <br />are to be installed in a sidewalk area, they must provide a minimum clearance of 4 <br />feet from either the face of the curb to the front edge of the pole, or from the rear <br />edge of the sidewalk to the rear edge of the pole. <br />(See Appendix G for Circuit Wiring Diagram Standard Detail) <br />O. Medians <br />Installation of medians is subject to City approval. Medians shall be designed in <br />accordance with the following design standards: <br />1. Median refuge islands shall be at least 6 feet wide between travel lanes and at <br />least 20 feet long. On priority bicycle routes the median refuge island shall be at <br />least 10 feet wide to accommodate bicycles with trailers and cargo bikes. <br />2. Median refuge islands shall provide an at -grade passage compliant with ADA <br />regulations through the island rather than using ramps and landings. <br />3. Vegetated median refuge islands shall not compromise the visibility of pedestrians <br />and bicyclists crossing in crosswalks. <br />4. Vegetated medians shall be a minimum of 8 feet wide. <br />Public Improvement Design Standards Manual, 2016 Page 2-28 <br />
