1. ALL EXPOSED EQGES SHALL BE ROUNDED TO A 15 rnm 2") RADIUS,
2- THE CURB FACE AT POINTS A AND 0 SHALL BE THE NORMAL CURB FACE OF THE ADJACENT CURB,
AT' POINTS 8 AND C, THE CURB FACE SHALL. BE THE NORMAL CURB FACE OF THE ADJACENT CURB
PLUS H (SEE APPLICABLE CATCH BASIN STANDARD PLAN.)
3. IN EXiSTMG STREETS WHERE NO PAVEMENT RECONSTRUCTION IS SPECIFIED ON THE PLANS,
THE ELEVATION OF' THE OUTER EDGE OF' THE LOCAL DEPRESSION SHALL MEET' THE FINISHED
STREET SURFACE,
4. IN NEW STREETS OR IN EXISTING STREETS WHERE PAVEMENT RECONSTRUCTION IS SPECIFIED ON THE
PLANS�
THE ELEVATIONS OF POINTS F AND G SHALL BE, SET Hl HIGHER THAN THE CUTTER FLOW LINE
ELEVATIONS AT POINTS A AND D, RESPECTIVELY.
THE ELEVATIONS OF POINTS P AND R SHALL BE SET H2 HIGHER THAN THE GUTTER FLOW LINE
ELEVATIONS AT POINTS 6 AND C, RESPECTIVEL,Y.
THE ELEVATION OF POINT S SHALL BE SET H2 HIGHER THAN THE ELEVATION AT THE NEAREST GUTTER
FLOW LINE.
WHERE THEK;. I$ NO GUTTER ADJACENT TO THE LOCAL. DEPRESSION, THE ELEVAlION OF POINT E
SHALL BE SET H3 HIGHER THAN THE ELEVATION AT THE NEAREST TOE OF CURB�
5. DIMENSIONS:
H, Hl, H2 AND H3 SHALL BE AS NOTED ON THE PLANS.
G = 600 mm (24")

I , WHERE THE BASIN IS TO BE CONSTRUCTED Mn-flN THE LIMITS OF EXISTING OR PROPOSED
SIDEWALK OR IS CONTIGUOUS TO SUCH SIDEWALK, THE TOP SLAB OF THE BASIN MAY BE
POURED EITHER MONOLITHIC WITH THE SIDEWALK OR SEPARATELY, USING THE SAME CLASS
OF CONCRETE AS IN THE BASIN, WHEN POURED MONOLITHICALLY, THE SIDEWALK SHALL BE
PRO\ADED WITH A WEAKENEQ PLANE: OR A 25 mm (I") DEEP SAWCUT CONTINUOUSI-Y AROUND
THE EXTERNAL PERIMETER OF THE CATCH BASIN WALLS, INCLUDING ACROSS THE FULL WIDTH
OF THE SIDEWALK. SURFACE OF ALL EXPOS�D CONCRETE SHALL CONFORM IN SLOPE, GRADE,
COLOR, FINISH, AND SCORING 'TO EXISTING OR PROPOSED CURB AND WALK ADJACENT TO THE
BASIN,
2. ALL CURVED CONCRETE SURFACES SHALl- BE FORMED BY CURVED FORMS, AND SHALL NOT BE
SHAPED BY PLASTERING.
3, FLOOR OF BASIN SHALL, BE GIVEN A STEEL TROWEL FINISH AND SHALL, HAVE A LONGITUDINAL
AND �ATERAL SLOPE OF 1:12 MINIMUM AND 1:3 MAXIMUM, EXCEPT WHERE THE GUTTER GRADE
EXCEEDS 8%, IN WHICH CASE THE LONGITUDINAL SLOPE OF THE FLOOR SHALL. BE
THE SAME AS THE GUTTER GRADE, SLOPE FLOOR FROM ALL DIRCCTIONS TO THE OUTLET,
4. DIMENSIONS:
B = 970 mm (3'-2")
V � THE DIFFERENCE IN ELEVATION BETWEEN THE TOP OF THE CURB AND THE INVERT OF
THE CATC14 BASIN AT THE OUTLET = 1.35 m (4.5').
v u = THE DIFFERENCE IN ELEVATION BETWEEN THE TOP OF THE CURB AND THE INVERT AT
THC UPSTREAM END OF THC BASIN, AND SHALL BE DETERMINED BY THE REQUiREME:NTS
OF NOTE 3, BUT SHALL NOT BE LESS THAN CURB FACE PLUS 300 mm (12"),
VI = THE DIFFERENCE IN ELEVATION BETWEEN THE TOP OF THE CURB AND THE INVERT OF
THE INLET, NOTED ON THE PLANS,
H = NOTED ON THE PLANS.
W = NOTED ON THE PLANS,
A = THE ANGLE, IN DEGREES, INTERCEPTED BY THE CENTERLINE OF THE CONNECTOR PIPE
AND THE CATCH BASIN WALL TO 'WHICH THE CONNECTOR PIPE IS ATTACHED,
5. PLACE CONNECTOR PIPES AS INDICATED ON THE PLANS. UNLESS OTHERWISE SPECIFIED.
THE CONNECTOR PIPE SHALL BE LOCATED AT THE DOWNSTREAM END OF THE SASfN,
WHERE THE QONNECTOR PIPE IS SHOWN AT A CORNER, THE CENTERLINE OF THE PIPE SHALL�
INTERSECT THE INSIDE CORNER OF THE BASIN, THE PIPE MAY BE CUT AND TRIMMED AT A
SKEW NECESSARY TO INSURE MINIMUM 80 mm -) PIPE EMBEDMENT, ALL AROUND, WITHIN
'THE CATCH BASIN WALL, AND 75 mm (3 RADIVS OF ROUNDING OF STRUCTURE CONCRETE,
ALL AROUND, ADJACENT TO PIPE ENDS. ") MONOLITHIC CATCH BASIN CONNECTION SHALL BE
USED TO JOIN THF, CONNECTOR PIPE TO THE CATCH BASIN WHENEVER ANOLE "A" IS LESS THAN
70' OR GREATER THAN 110", OR WHENEVER THE CONNECTOR PIPE IS LOCATED
IN A CORNER. THE OPTtONAL USE OF A MONOLITHIC CATCH BASIN CONNECTION IN ANY CASE
IS PERMITTED. MONOLITHIC CATCH BASIN CONNECTIONS MAY BE CONSTRUCTED TO AVOID
CUTTING STANDARD LENGTHS OF PIPE.
6� STEPS SHALL BE LOCATED AS SHOWN. IF THE CONNECTOR PIPE INTERFERES NTH THE STEPS,
THEY SHALL BE LOCATED AT THE CENTERLINE OF THE DOWNSTREAM END WALL. STEPS SHALL
BE SPACED 300 mm 12" APART, THE TOP STEP SHALL 8E 175 mm (7 BELOW THE TOP OF -n-iE
