RE: Review Rainier View estates
Only 1 gate valve will be required at Sta. # 4+86.87
The Sewer main is too deep where it is shown as lowered below the lateral storm pipe crossings.
Details shown on the drawings are obsolete. Details 7-20, 7-25, 7-2 and 7-21 have been changed and these changes need to be reflected on these drawings.
An “Air Release Assembly” will be required at Sta. # 0+90.00
The bend at Sta. # 4+86.87 should be accomplished using 2, 45-degree fittings rather than a 90 degree fitting.
All Service line valve boxes must be located 10’ from all water service valve boxes
