PROJECT NOTES (c) Vertical and horizontal separations between telecommunications facilities and other facilities shall be maintained as required by the NESC Section 32 Underground Conduit Systems. Conduit systems for telecommunications facilities shall be separated from conduit systems for power supply systems by: (1) 3 inches of concrete (2) 4 inches of masonry (3) 12 inches of well -tamped earth Warning Tape (a) A detectable orange colored cable warning tape shall be placed 12 to 18 inches above, the conduit in the trench. Hand -holes (a) All cavities required for cable pulling purpose shall be constructed as load bearing Hand -holes. (b) Hand -holes shall be placed at as specified on plans and approved by Viaero fiber Networks.. In no case shall conduit bend radius exceed 180 degrees between structures. Hand -holes shall be either a 48"x30"x24" precast composite concrete or a 24"x36"x24" precast composite concrete. Refer to project detail sheet 64 for specifications. Separations from Other Public Utilities and Drainage Facilities (a) Parallel separations are required to satisfy standards for utility trenching excavations and to provide for adequate maintenance operations. (1) The minimum parallel separation between telecommunications conduit and water pipe or drainage pipe and other pipe with a depth of cover of less than 6 feet shall be 5 feet. (2) The minimum parallel separation between telecommunications conduit and wastewater pipe or other pipe with a depth of cover of more than 6 feet shall be 10 feet. (b) Vertical separation at utility crossings shall be as follows: (1) The minimum vertical separation between telecommunications conduit and City public utilities shall be 6 inches. All crossings of natural and improved drainage ways, and irrigation ditches, shall meet the following conditions: (1) Telecommunications conduit shall be placed a minimum 48 inches below the invert of the drainage way or ditch. This minimum depth of cover shall apply whether or not the drainage way is an open system or contained within a culvert. (2) The telecommunications conduit shall be placed in a SDR -11 to accomidate placed conduits. When the drainage way or ditch is an open system, the sleeve shall extend a minimum horizontal distance of 10 feet beyond each side of the drainage way, measured from top of bank to top of bank. (3) When the drainage way or ditch is in a culvert, and the culvert opening is greater than 5 feet, the sleeve shall extend a minimum horizontal distance of 5 feet beyond each side of the culvert, or shall extend a minimum horizontal distance equal to the vertical depth of the culvert, measured from the culvert invert to the final ground surface above the culvert. <o■c31.ii[3®e®o X LEGEND S Itlr SIGN DRE HYDRANT WATER METER GAS METIER ELECTRIC METER UTUTY VALVE W ITTY POLE W ITTY MANHOLE EXISTING STCRM MAIMOLE CASING STREET uGNT EASING WITTY HANOHOLE EIECIBCAL/IITUTY CABINET ILERHONE PED - CROSS BOM PROPOSED NAERO MANHOLE 495900D NAERO HANDHCLT STORM INET STORM GRATE CULVERT TREE BORE RT EXISTING MELT EASING LANDSCAPE AREA E)0 11NG POLE 501 TOMER EASING RR CROSSING ARM LINETYPES -- CD01AT-IDT M 0006RAC1 ONF COW1-1RDKN COWT-CRECTYNLL 91,0 AAM -O -IAT EDGE GE A�rVLT EDGE OF GRAIL EDGE O WINK TAE INCE-ESSING 1000 FENCE-El]SOIG 01060 01-D3SI11G RRAAOIIFDOSING GAS-E0STRG 110906+010 E06 -901E16110 9001111ID pECIFV- ASTIR BIPED ran-ETS1NC MEMO( -EASING 01900190-0951006 SMART SEAR -ENING MIN 161ER-0ISRIG AADNGtSSING DATE CREATED: 1/16/2023 DATE REVISED 9/28/2023 DATE PLOTTED: 9/28/2023 DRAWN BY: D.
