[ ] *Note scale, if different than 1" = 4'.
[ ] Stationing (every 100') and elevation (every 5') of grid.
[ ] T.C. grade each side and/or surface over sewer when applicable.
[ ] Open circle at grade breaks (-0-).
[ ] Station and elevation at surface for grade breaks, intersections, change in conditions.
[ ] Identical points flagged as such.
[] *Where clearance (from sewer to object) is .5 feet to 1.5 feet, encase per STD. S-23. Where clearance is less than .5 feet, use Ductile iron pipe.
[] *Chimneys are required where depth of main line sewer is 15 feet or more.
[ ] Cradling or encasement is required where depth of main line sewer is 20 feet or more.
[ ] 0.75 feet between outlet elevation and the bottom (base) of MH structure.
[ ] Sewer grades should be in multiples of 0.40% if practical.
[ ] Use lettered section designations only when two or more sections appear on one page.
[ ] Lower manhole on each view to be shown dashed if shown solid on any other view.
[ ] *Backwater valves are required when pads serviced by a main sewer line are lower in elevation than the next upstream MH.
[ ] Avoid use of vertical curves. Minimum length of vertical curve shall be 40 feet. Elevation and station to be shown every 10 feet
