1. All conflicts between water lines and storm drainage, sanitary sewers and other items covered by detailed plans and profile.
2. Profile scale of one inch equals fifty feet (1" = 50') horizontal, and one inch equals five feet (1" = 5') vertical.
3. Plan view scale one inch equals fifty feet (1" = 50').
4. North arrow and scale.
5. Lot lines, lot numbers, block numbers and location dimensions.
C. Detail Drawings:
1. Shall be required for all special structures.
2. City standard drawings shall be used for all standard waterworks improvements.
D. Design: The design of waterworks improvements shall be as follows:
1. All waterworks improvements shall conform to OSDH engineering bulletin 0289, "Standards For Public Water Supply Facilities", latest revision.
2. All waterworks improvements shall conform to the "City Of Enid Standard Construction Specifications", as amended.
3. All water lines shall be placed in public right of way, unless prior approval of the director of engineering services is acquired for placing water lines in easements.
4. When water lines and service lines cross existing or proposed streets or alleys, the trench shall be backfilled from right of way to right of way with select materials and compacted to ninety five percent (95%) standard proctor density, unless the crossing was accomplished by boring.
5. Bench marks shall be USGS datum and shown on the plans.
6. All land lines shall be shown, dimensioned, and location referenced thereto.
7. No water line shall be installed without dedication of right of way.
8. Drawings shall show all obstructions, existing and proposed, above and below grade, located vertically and horizontally.
9. Drawings shall show existing and proposed elevations at all fire hydrant locations.
10. Water lines shall be placed with a minimum of three feet (3') of cover and at three and one-half feet (31/2') outside back of curb.
11. Public water supply systems must be designed to connect the existing main system at two (2) locations to provide a looped system.
12. Connection to existing water mains shall be by use of a tapping sleeve and valve.
13. Service lines shall be placed across existing or proposed roadways to serve existing and future lots.
14. Fire hydrants shall be placed in compliance with the 2006 international fire code, appendix C, table C105.1 and appendix D. Fire hydrants shall be located at property lines and intersections whenever possible.
15. Whenever a line is dead ended, including cul-de-sacs, it shall have a fire hydrant and the line will be connected to the nearest cross main by a two inch (2") PVC pipe to ensure circulation of water.
16. All water line extensions shall be in accordance with the most current master water plan. Water lines shall be sized at a minimum of sixteen inches (16") for section line roads; ten inches (10") for collection streets and eight inches (8") for local streets. Water lines shall be placed in the street right of way opposite from the sanitary sewer lines, when both must be placed in the street right of way. Fire flows will be determined by a fire flow analysis done in accordance with the 2006 international fire code, appendix B, "fire flow requirements for buildings".
E. Cost Estimate: A cost estimate, based on the city standard specifications pay quantities, shall be submitted with construction plans for water improvements.
F. As Built Plans:
1. As built plans with the exact location of all lines, valves, service lines, and fire hydrants shall be submitted to the director of engineering services before final approval of construction and issuance of a building permit for lots serviced by the improvements.
2. Final cost estimates for construction shall also be submitted with the as builts. (Ord. 2008-30, 11-4-2008)
