PROJECT NOTES <br />(c) Vertical and horizontal separations between telecommunications facilities and other <br />facilities shall be maintained as required by the NESC Section 32 Underground Conduit Systems. <br />Conduit systems for telecommunications facilities shall be separated from conduit systems for <br />power supply systems by: <br />(1) 3 inches of concrete <br />(2) 4 inches of masonry <br />(3) 12 inches of well -tamped earth <br />Warning Tape <br />(a) A detectable orange colored cable warning tape shall be placed 12 to <br />18 inches above, the conduit in the trench. <br />Hand -holes <br />(a) All cavities required for cable pulling purpose shall be constructed as <br />load bearing Hand -holes. <br />(b) Hand -holes shall be placed at as specified on plans and approved by Viaero.. <br />In no case shall conduit bend radius exceed 180 degrees between structures. <br />Hand -holes shall be either a 48"x30"x24" precast composite concrete or a 24"x36"x24" <br />precast composite concrete. Refer to project detail sheet 64 for specifications. <br />Separations from Other Public Utilities and Drainage Facilities <br />(a) Parallel separations are required to satisfy standards for utility trenching <br />excavations and to provide for adequate maintenance operations. <br />(1) The minimum parallel separation between telecommunications conduit <br />and water pipe or drainage pipe and other pipe with a depth of cover of less than <br />6 feet shall be 5 feet. <br />(2) The minimum parallel separation between telecommunications conduit <br />and wastewater pipe or other pipe with a depth of cover of more than 6 feet shall <br />be 10 feet. <br />(b) Vertical separation at utility crossings shall be as follows: <br />(1) The minimum vertical separation between telecommunications conduit <br />and City public utilities shall be 6 inches. <br />All crossings of natural and Improved drainage ways, and irrigation ditches, <br />shall meet the following conditions: <br />(1) Telecommunications conduit shall be placed a minimum 48 inches below the invert <br />of the drainage way or ditch. This minimum depth of cover shall apply whether or not the <br />drainage way is an open system or contained within a culvert. <br />(2) The telecommunications conduit shall be placed in a SDR -11 <br />to accomidate placed conduits. When the drainage way or ditch is an open system, the sleeve <br />shall extend a minimum horizontal distance of 10 feet beyond each side of the drainage way, measured <br />from top of bank to top of bank. <br />(3) When the drainage way or ditch is in a culvert, and the culvert opening is greater <br />than 5 feet, the sleeve shall extend a minimum horizontal distance of 5 feet beyond each <br />side of the culvert, or shall extend a minimum horizontal distance equal to the vertical depth of <br />the culvert, measured from the culvert invert to the final ground surface above the culvert. <br />LEGEND <br />v STREET SIGN <br />FIRE HYDRANT <br />WATER ME1ER <br />.s UTILITY VALVE <br />® <br />VIM POLE <br />© UTILITY MANHOLE <br />0 ELECIRICAL HH - TRAFFIC HH <br />FD TELEPHONE PED - CROSS BOX <br />III PROPOSED NAERO MANHOLE <br />o PROPOSED NAERO HANDHOLE <br />TREE <br />Lti STORM INLET <br />LINETYPES <br />At- <br />COOUT-110111 CONTRACT <br />cewT-(IRE101 / PON) <br />COAT-ORECTONAl BORE <br />RIGHT -OF -VAT <br />EDGE a ASPHALT <br />CAS-01511NC <br />TEIHNOE-E1S1114 <br />5 5 <br />SEVER-rY15TNC <br />SNRIFT SLIP -05111G <br />SiFJ.11-01SVIG <br />WATER -WNW <br />LLC <br />MN VA LONG <br />amok. a -o. <br />woe, r.
