CURVATURE OF THE LIP AND SIDEWALLS AT GUTTER OPENING SHALL BE FORMED BY CURVED FORMS AND SHALL NOT BE MADE BY PLASTERING. WALL THICKNESS (T) T = 6 INCHES IF H IS 8 FEET OR LESS T = 8 INCHES IF H EXCEEDS 8 FEET. FLOOR OF BASIN SHALL BE TROWELED AN RETROWELED TO PRODUCE A HARD, POLISHED SURFACE OF MAXIMUM DENSITY AND SMOOTHNESS. SLOPE OF FLOOR PARALLEL WITH CURB SHALL BE 1 TO 12 UNLESS OTHERWISE SPECIFIED. MANHOLE SHALL BE PLACED AS SHOWN ON IMPROVEMENT PLANS. OUTLET PIPE SHALL BE TRIMMED TO THE FINAL SHAPE AND LENGTH BEFORE CONCRETE IS POURED. REINFORCING STEEL SHALL BE #4 ROUND DEFORMED BARS, OR WIRE MESH AS INDICATED.
