I. WHEN DEPTH M FROM STREET GRADE TO THE TOP OF THE BOX IS LESS
THAN 2'-10 1/2" FOR PAVED STREETS OR 3'-60 FOR UNPAVED STREETS,
CONSTRUCT SHAF- PER SECTION C -C AND DETAIL "No. DEPTH M MAY BE
REDUCED TO AN ABSOLUTE LIMIT OF 6" WHEN LARGER VALUES OF M
WOULD REDUCE H IN SECTION 'C -C TO 3'-6* OR LESS.
2.. H (IN SECTION A -A AND B -B) SHALL NOT BE LESS THAN 4'-0', BUT MAY
BE INCREASED PROVIDED THAT THE VALUE OF M SHALL NOT BE LESS
THAN THE MINIMUM SPECIFIED AND THAT THE REDUCER SHALL BE USED.
FOR H (IN SECTI O14 C -C) SEE NOTE I.
3. L SHALL BE 4'-0" UNLESS OTHERWISE SHOWN. L MAY BE INCREASED OR
LOCATION OF MANHOLE SHIFTED TO MEET PIPE ENDS. BUT ANY CHANGE
IN LOCATION OF THE SPUR MUST BE APPROVED BY THE ENGINEER.
4. T SHALL BE 8" FOI VALUES OF H UP TO AND INCLUDING 8'-0" AND 10" FOR
VALUES OF H OVEP 8' -on.
5. STATIONS OF MANHOLES SHOWN ON PROJECT DRAWINGS APPLY AT
CENTER LINE OF SHAFT. ELEVATIONS ARE SHOWN AT CENTER LINE OF
SHAFT AND REFER TO THE PROLONGED INVERT GRADE LINES. SEE NOTE 3.
6. REINFORCEMENT SHALL CONFORM TO ASTM A 615, GRADE 40. AND SHALL
TERMINATE 11/2" CLEAR OF CONCRETE SURFACES UNLESS OTHERWISE
SHOWN.
7. FLOOR OF MANHOLE: SHALL BE STEEL TROWELED TO SPRING LINE.
8. BODY OF MANHOLE SHALL BE POURED IN ONE CONTINUOUS OPERATION
EXCEPT THAT A CONSTRUCTION JOINT WITH A LONGITUDINAL KEYWAY
MAY BE PLACED AT SPRING LINE.
9. THICKNESS OF THE DECK SHALL VARY WHEN NECESSARY TO PROVIDE
A LEVEL SEAT BUT SHALL NOT BE LESS THAN 8-
10. STEPS SHALL CONFORM TO STANDARD PLAN 635 OR 636. UNLESS OTHERWISE
SHOWN, STEPS SHALL BE UNIFORMLY SPACED 14" TO 15" OC. THE LOWEST
