WHERE'THE BASIN IS TO BE CONSTRUCTED WITHIN 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 PROVIDED WITH A WEAKENED PLANE OR A 25 mm(Io) 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 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 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. 4.

UNLESS OTHERWISE SPECI- FIED. 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 80 mm(30) PIPE EMBEDMENT. ALL AROUND, WITHIN THE CATCH BASIN WALL. AND 75 mm(30) 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 CORNER. THE OPTIONAL USE OF A MONOLITHIC CATCH BASIN CONNECTION IN ANY CASE IS PERMITTED. MONOLITHIC CATCH BASIN CONNECTIONS MAY BE CONSTRUCTED TO AVOID CUT- TING 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 300 mm(120) APART. THE TOP STEP SHALL BE 175 nwn(71 BELOW THE TOP TO THE MANHOLE AND PROJECT 65 nwn(2-1/2'). ALL OTHER STEPS SHALL PROJECT 130 nwn(50). 7. DOWELS ARE REQUIRED AT EACH CORNER AND AT 2 m(79 ON CENTER (MAXIMUM) ALONG THE BACKWALL. 8.
