NOTES:
1. ALL EXISTING WATER AND SEWER MAINS AND SERVICES SHALL BE ABANDONED IN PLACE
WITH FLOWABLE FILL ONCE ALL PROPOSED MAINS AND SERVICES ARE IN OPERATION.
2. ALL SEWER MANHOLES TO HAVE WATERTIGHT MANHOLE RINGS AND COVERS. COVERS TO BE
SET TO FINAL GRADE AND MATCHING FINAL PAVEMENT ELEVATIONS ACROSS COVERS.
3. PROPOSED WATER VALVES ARE TO BE SET WITHIN 1' OF PROPOSED TEES.
4. UTILITY SEPARATION REQUIREMENTS:
• WHEN INSTALLING WATER AND/OR SEWER MAINS, THE HORIZONTAL SEPARATION BETWEEN
UTILITIES SHALL BE 10'. IF THIS SEPARATION CANNOT BE MAINTAINED DUE TO EXISTING
CONDITIONS, THE VARIATION ALLOWED IS THE WATER MAIN IN A SEPARATE TRENCH WITH
THE ELEVATION OF THE WATER MAIN AT LEAST 18" ABOVE THE TOP OF THE SEWER
AND MUST BE APPROVED BY THE PUBLIC UTILITIES DIRECTOR. ALL DISTANCES ARE
MEASURED FROM OUTSIDE DIAMETER TO OUTSIDE DIAMETER
• WHERE IT IS IMPOSSIBLE TO OBTAIN PROPER SEPARATION, OR ANYTIME A SANITARY
SEWER PASSES OVER A WATERMAN, DIP MATERIALS OR STEEL ENCASEMENT EXTENDED
10' ON EACH SIDE OF CROSSING MUST BE SPECIFIED AND INSTALLED TO WATERLINE
SPECIFICATIONS
• MAINTAIN 18" MIN. VERTICAL SEPARATION AT ALL WATERLIANN & RCP STORM DRAIN
CROSSINGS; MAINTAIN 24" MIN. VERTICAL SEPARATION AT ALL SANITARY SEWER & RCP
STORM DRAIN CROSSINGS. WHERE ADEQUATE SEPARATIONS CANNOT BE ACHIEVED,
SPECIFY DIP MATERIALS AND A CONCRETE CRADLE HAVING 6" MIN. CLEARANCE.
• ALL OTHER UNDERGROUND UTILITIES SHALL CROSS WATER AND SEWER FACILITIES WITH
18" MIN. VERTICAL SEPARATION REQUIRED
5- EXISTING UTILITIES AND STRUCTURES SHOWN, BOTH UNDERGROUND AND ABOVE GROUND,
ARE BASED ON A FIELD SURVEY AND THE BEST AVAILABLE RECORD DRAWINGS. THE
CONTRACTOR SHALL VERIFY FIELD CONDITIONS PRIOR TO BEGINNING RELATED
CONSTRUCTION. ANY DISCREPANCIES SHALL BE REPORTED TO THE OWNER'S
REPRESENTATIVE IMMEDIATELY.
6. ALL EXISTING STORM THAT IS IN CONFLICT WITH CONSTRUCTION OF PROPOSED SANITARY OR
WATER IS TO BE REMOVE AND REPLACE.
7. CONTRACTOR TO INSTALL AND ACTIVATE PROPOSED SEWER AND WATER SYSTEMS PRIOR TO
INSTALLATION OF PROPOSED DRAINAGE SYSTEM PIPE.
8. ABANDON EXISTING SEWER AND WATER SYSTEMS, INCLUDING SERVICES, ONCE PROPOSED
SYSTEMS ARE CERTIFIED AND ACTIVATED. GROUT FILL ANY PIPE NOT REMOVED AND CAPPED.
9. CATCH BASINS 1, 2, 16, AND 17 ARE 4'X6' BOXES. ALL OTHER CATCH BASINS ARE 4'X4'
BOXES.
10. INSTALL TEMPORARY SILT FENCING ALONG THE ROAD RIGHT-OF-WAYS AND AT ALL EXISTING
AND PROPOSED CATCH BASINS.
11. FILTER BAGS TO BE USED IN THE DEWATERING PROCESS.
12. DISTANCES SHOWN ARE HORIZONTAL SURFACE MEASUREMENTS.
13. NAD 83 SCALE FACTOR = 0.9999235
14. ALL DISTURBED PROPERTY CORNERS SHALL BE REPLACED AT THE END OF CONSTRUCTION
BY A LICENSED SURVEYOR AND AT THE CONTRACTORS EXPENSE.
