EM A DETAILED INSTALLATION AND MAINTENANCE SCHEDULE DURING THE VAROUS PHASES OF CONSTRUCTION IS OUTLINED IN SECTION 3 OF THE SWPPP BOOK. ROUGH GRADING: INSTALL CATCHBASIN INLET PROTECTION, INSTALL STRAW OR FILTER ROLLS AT BACK OF CURB AND AT EDGE OF GRADING. THE EXISTING GROUND DOES NOT HAVE A DEFINED DIRECTION OF FLOW. A CONSTRUCTION ENTRANCE SHALL BE INSTALLED PRIOR TO COMMENCING GRADING OPERATIONS. PAYING: INSTALL STRAW OR FILTER ROLLS AT NEW BACK OF WALK MANTAIN PROTECTION AT CATCHBASIN, INSTALL ROCK BAGS IN GUTTER PAN.
