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 PROVIDED WITH A
WEAKENED PLANE OR A 1 -INCH DEEP SAWCUT CONTINUOUSLY AROUND THE EXTERNAL PERIMETER
OF THE CATCH BASIN WALLS, INCLUDING ACROSS THE FULL WIDTH OF THE SIDEWALK, SURFACE OF
ALL EXPOSED 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 FORMES) BY CURVED FORMS, AND SHALL NOT BE
SHAPED BY PLASTERING.
3. FLOOD OF BASIN SHALL BE GIVEN A STEEL TROWEL FINISH AND SHALL HAVE A LONGITUDINAL AND
LATERAL SLOPE OF 1:12 MINIMUM AND 1:3 MAXIMUM, EXCEPT WHERE THE GUTTER GRADE EXCEEDS
8 PERCENT, IN WHICH CASE THE LONGITUDINAL SLOPE OF THE FLOOR SHALL BE THE SAME AS THE
GUTTER GRADE. SLOPE FLOOR FROM ALL. DIRECTIONS TO THE OUTLET.

THE CONNECTOR PIPE SHALL. BE LOCATED AT THE DOWNSTREAM END OF THE BASIN. WHERE THE
CONNECTOR 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 3 -INCH PIPE EMBEDMENT, ALL AROUND, WITHIN THE CATCH BASIN WALL, AND
3 -INCH RADIUS OF ROUNDING OF STRUCTURE CONCRETE, ALL. AROUND, ADJACENT TO PIPE ENDS. A
MONOLITHIC CATCH BASIN CONNECTION SHALL, BE USED TO JOIN THE CONNECTOR PIPE TO THE
CATCH BASIN WHENEVER ANGLE `A" IS LESS THAN 70 DEGREES OR GREATER THAN 110 DEGREES,
OR WHENEVER THE CONNECTOR PIPE IS LOCATED IN A CORDER. THE OPTIONAL. 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 WITH THE STEPS,
THEY SHALL BE LOCATED AT THE CENTERLINE OF THE DOWNSTREAM END WALL. STEPS SHALL BE
SPACED 12 INCHES APART. THE TOP STEP SHALL BE 7 INCHES BELOW THE TOP TO THE MANHOLE
AND PROJECT 2-l12 INCHES. ALL OTHER STEPS SHALL PROJECT 5 INCHES.
