NOTES
I. JUNCTION STRUCTURE NO. 2 SHALL BE USED WHEN THE OUTSIDE DIAMETER
OF THE LATERAL IS GREATER THAN 1/2 THE INSIDE DIAMETER D OF THE
MAIN LINE: OR WHEN THE INSIDE DIAMETER B OF THE LATERAL IS GREATER
THAN 24". B SHALL NOT EXCEED 3/4 D OR 39'.
2. IF THE MAIN LINE IS A REINFORCED MONOLITHIC ARCH STORM DRAIN,
D SHALL REFER TO THE CLEAR SPAN OF THE ARCH. REINFORCING STEEL
SHALL BE CUT AND BENT INTO THE JUNCTION STRUCTURE IN THE SAME
MANNER AS FOR A PIPE. A CONCRETE CRADLE IS NOT REQUIRED FOR A
REINFORCED MONOLITHIC ARCH.
3. STATIONS SHOWN ON THE PROJECT DRAWINGS APPLY AT THE INTERSECTION
OF CENTER LINES OF MAIN LINE AND LATERAL, EXCEPT THAT STATIONS FOR
CATCH BASIN CONNECTOR PIPES APPLY AT THE INSIDE WALL OF MAIN LINE.
4. VALUES. FOR A. B. C AND D SHALL BE SHOWN ON THE PROJECT DRAWINGS.
ELEVATION R AND ELEVATION S SHALL BE SHOWN ONLY WHEN REQUIRED PER
NOTE 5.
5. a. ELEVATIONS R AND S NEED NOT BE SHOWN ON THE PROJECT DRAWINGS
IF THE INLET PIPE IS TO ENTER THE MAIN LINE RADIALLY.
b. ELEVATION R SHALL BE SHOWN ON THE PROJECT DRAWINGS ONLY IF A
STUB I.S TO BE PROVIDED IN THE MAIN LINE FOR FUTURE CONNECTION
OF AN INLET PIPE.
c. ELEVATION S SHALL BE SHOWN ON THE PROJECT DRAWINGS IF AN INLET
PINE IS TO ENTER THE MAIN LINE OTHER THAN RADIALLY. INLET PIPE
SHALL BE LAID ON A STRAIGHT GRADE FROM ELEVATION S TO THE
CATCH BASIN OR GRADE BREAK IN LINE.
6.. THE INLET PIPE SHALL ENTER THE MAIN LINE RADIALLY UNLESS OTHERWISE
INDICATED. THE INLET PIPE MAY ENTER THE MAIN LINE OTHER THAN
RADIALLY IF ANGLE A IS GREATER THAN 450, B IS LESS THAN OR EQUAL TO
24" AND THE OUTSIDE DIAMETER OF THE INLET PIPE IS LESS THAN 1/2 D:
OTHERWISE. STANDARD PLAT! 3042 SHALL BE USED.
7. NO MORE THAN ONE OPENING SHALL BE MADE IN ANY ONE SECTION OF PIPE.
8. THE OPENING FOR THE BREAKOUT SHALL BE RECTANGULAR AND CUT NORMAL
TO THE PIPE SURFACE WITHOUT DAMAGING THE REINFORCING STEEL. THE
TRANSVERSE REINFORCEMENT OF THE MAIN LINE SHALL BE CUT AT THE
CENTER OF THE OPENING AND BENT INTO THE TOP AND BOTTOM SLABS OF
THE SPUR.
9. THE MAIN LINE SHALL BE REINFORCED WITH A CONCRETE CRADLE AND
ENCASEMENT (AS APPLICABLE). A CONCRETE ENCASEMENT IS REQUIRED IF A
JOINT IN THE MAIN LINE FALLS WITHIN THE LIMITS OF THE CRADLE. THE
CONCRETE ENCASEMENT SHALL EXTEND 12" ABOVE THE TOP OF THE MAIN
LINE AND TO THE LIMITS OF THE CRADLE.
IF CONNECTING TO AN EXISTING STORM DRAIN, PORTION OF CRADLE
OPPOSITE INLET MAY BE OMITTED.
10. REINFORCING STEEL SHALL CONFORM TO ASTM A 615, GRADE 40, AND BE
PLACED 1 1/2" CLEAR FROM CONCRETE SURFACES, UNLESS OTHERWISE
SHOWN F BARS SHALL BE CARRIED TO A POINT NOT LESS THAN J
DISTANCE FROM CENTER LINE WITH J=7D/12 + 6".
11. FLOOR OF THE SPUR SHALL BE STEEL -TROWELED TO THE SPRING LINE OF
THE SPUR.

GENERAL NOTE
I. DIMENSIONS SHOWN ON THIS PLAN FOR METRIC AND ENGLISH UNITS ARE
NOT EXACT EQUAL VALUES. IF METRIC VALUES ARE USED, ALL VALUES
USED FOR CONSTRUCTION SHALL BE METRIC VALUES, EXCEPT REINFORCING
BARS SIZES IN ENGLISH UNITS MAY BE SUBSTITUTED FOR METRIC BAR
SIZES. IF ENGLISH UNITS ARE USED, ALL VALUES USED FOR CONSTRUCTION
SHALL BE ENGLISH UNITS.
NOTES
CASE I AND CASE 3
I. OUTSIDE DIAMETER OF THE CONNECTOR PIPE SHALL NOT BE GREATER
THAN 1/2 THE INSIDE DIAMETER OF THE RCP MAIN LINE.
2. INSIDE DIAMETER D OF THE CONNECTOR PIPE SHALL NOT BE GREATER
THAN 600 mm (24").
3. THE MINIMUM OPENING INTO THE EXISTING STORM DRAIN SHALL BE THE
OUTSIDE DIAMETER OF THE CONNECTING PIPE PLUS 30 mm (I").
THE CONCRETE BACKFILL SUPPORTING THE CONNECTING PIPE MAY BE
OMITTED IF THE PIPE IS LAID ON UNDISTURBED EARTH TO STORM DRAIN
WALL.
4. ALL CSP AND FITTINGS SHALL BE GALVANIZED. BAND CONNECTORS MAY
BE 2 GAGES LIGHTER THAN THE PIPE. BUT WITH A MINIMUM GAGE OF 16.
THEY SHALL BE CONNECTED AT THE ENDS BY ANGLES HAVING MINIMUM
DIMENSIONS OF 50 mm x 50 mm x 5 mm (2"x2"x3/16") AND 140 mm -(5 1/20)
BOLTS.
5. WHEN JOINING A RCP CONNECTOR PIPE TO A CSP CONNECTOR PIPE. THE
INSIDE DIAMETER D OF THE CSP SHALL BE AT LEAST EQUAL TO BUT
NOT MORE THAN 75 mm (3") GREATER THAN THAT OF THE RCP.
6. CONNECTOR PIPES SHALL BE NOT MORE THAN 1.5 m (5') ABOVE THE INVERT.
7. CONNECTOR PIPES SHALL ENTER MAIN LINE RCP RADIALLY.
8. WHEN CONNECTING TO A RCB, STANDARD PLAN 333 SHALL BE USED IF
THE TOP OF THE CONNECTOR PIPE IS LESS THAN 300 mm (121 BELOW
THE SOFFIT OF THE RCB OR THE FLOW LINE OF THE PIPE IS LESS
THAN 330 mm (130) ABOVE THE FLOOR OF THE RCB AT THE INSIDE FACE.
CASE 2
9. SADDLE. CONNECTIONS SHALL BE USED WHEN CONNECTING TO PIPES 525mm
(21") OR LESS IN DIAMETER WITHOUT THE USE OF JUNCTION STRUCTURES
OR PRECAST Y BRANCHES.
10. TRIM OR CUT SADDLE TO FIT SNUGLY OVER THE OUTSIDE OF THE MAIN
PIPE. SO ITS AXIS WILL BE ON THE LINE AND GRADE OF THE CONNECTING
PIPE.
11. THE OPENING INTO THE PIPE SHALL BE CUT AND TRIMMED TO FIT THE
SADDLE SO THAT NO PART WILL PROJECT WITHIN THE BORE OF THE
SADDLE PIPE,
12. THE CONNECTOR PIPE SHALL BE SUPPORTED AS SHOWN IN CASE I AND
CASE 3.
