STORM WATER POLLUTION PREVENTION PLAN WITH THE EXCEPTION OF PROPERLY DESILTED WATER FROM SITE DEWATERING, THE CONTRACTOR SHALL NOT DISCHARGE ANY MATERIALS AND/OR LIQUIDS TO THE STORM DRAINAGE SYSTEM. ACTIVITIES OF PARTICULAR CONCERN ARE: A. CONTRACTOR SHALL DESIGNATE A CONCRETE TRUCK CLEAN—OUT AREA. CITY INSPECTOR APPROVED BEST MANAGEMENT PRACTICES SHALL AT ALL TIMES BE FULLY IMPLEMENTED AT AND AROUND THE CLEAN—OUT AREA. B. TACK COAT AND PRIME COAT ASPHALTS SHALL BE CAREFULLY SPRAYED AND ANY EXCESS MATERIAL SPILLED SHALL BE CLEANED UP IMMEDIATELY BY PROPER METHODS. C. ALL EQUIPMENT REFUELING IN THE PROJECT AREA SHALL BE CAREFULLY DONE TO AVOID SPILLAGE. ANY SPILLS SHALL BE CONTAINED AND CLEANED UP IMMEDIATELY IN ACCORDANCE WITH STATE AND LOCAL REQUIREMENTS. ALL FUELING VEHICLES SHALL BE EQUIPPED WITH SPILL CLEANUP MATERIALS AND EQUIPMENT. D. CONTRACTOR SHALL CONTROL AND PROPERLY DISPOSE OF ALL LIQUIDS DURING SAWCUTTING ACTIVITIES EROSION CONTROL NOTES: 1. ALL EROSION CONTROL MEASURES SHALL BE CONSTRUCTED PER THE STANDARD CONSTRUCTION SPECIFICATIONS DATED OCTOBER 1997 AND THE EROSION AND SEDIMENT CONTROL STANDARDS AND SPECIFICATIONS, LATEST REVISION. WHERE DISCREPANCIES EXIST THE STANDARD DRAWINGS OF THE EROSION AND SEDIMENT CONTROL STANDARDS AND SPECIFICATIONS SHALL SUPERSEDE THE STANDARD DRAWINGS OF THE STANDARD CONSTRUCTION SPECIFICATIONS. 2. ALL EROSION CONTROL MEASURES SHALL BE MAINTAINED DURING CONSTRUCTION BY THE CONTRACTOR PER THE EROSION AND SEDIMENT CONTROL STANDARDS AND SPECIFICATIONS, LATEST REVISION. 3. DUST CONTROL SHALL BE PRACTICED PER THE GRADING ORDINANCE AND STANDARD CONSTRUCTION SPECIFICATIONS, LATEST REVISION. 4. INLET FILTERS SHALL BE PLACED AROUND ALL DRAIN INLETS WHICH COULD RECEIVE DRAINAGE IN UNPAVED AND PAVED AREAS DURING THE WET SEASON (OCTOBER 1—APRIL 15). 5. STORM DRAIN INLET FILTERS PER ATTACHED DETAIL SHALL BE PLACED ON ALL DRAIN INLETS AFTER COMPLETION OF PAVING AND SHALL REMAIN IN PLACE ON A YEAR ROUND BASIS. FILTERS SHALL BE REMOVED BY THE CONTRACTOR UPON ACCEPTANCE OF SUBDIVISION IMPROVEMENTS. 6. STABILIZED CONSTRUCTION SITE ACCESS SHALL BE CONSTRUCTED PER ATTACHED DETAIL WHERE CONSTRUCTION TRAFFIC ENTERS OR LEAVES PAVED AREAS. THE STABILIZED ACCESS SHALL REMAIN IN PLACE ON A YEAR ROUND BASIS UNTIL COMPLETION OF CONSTRUCTION. 7. SENSITIVE AREAS AND AREAS UNDISTURBED BY GRADING SHALL BE PROTECTED BY FILTER ROLL BARRIER AS SHOWN ON THE ROUGH GRADING PLAN AND CONSTRUCTED PER ATTACHED DETAILS. FILTER ROLL BARRIER, OR APPROVED EQUAL, SHALL REMAIN IN PLACE ON A YEAR ROUND BASIS. 8. FILTER ROLL, STRAW WATTLE BARRIER OR OTHER EROSION CONTROL MEASURES BE CONSTRUCTED PER ATTACHED DETAILS, TO PROVIDE PROTECTION AT THE PERIMETER OF THE PROJECT WHERE SHEET FLOW TYPE RUNOFF MAY DISCHARGE TO ADJACENT PROPERTIES. STRAW ROLL, OR APPROVED EQUAL, SHALL REMAIN IN PLACE ON A YEAR ROUND BASIS, 9. THE FIRST 18' BEHIND THE SIDEWALK ON LOT FRONT YARDS, THE FIRST 7.5' BEHIND THE SIDEWALK ON STREET SIDEYARDS AND ALL SLOPES STEEPER THAN 10:1 SHALL BE HYDROSEEDED WITH AN APPROVED SEED MIXTURE AFTER COMPLETION OF CURB, GUTTER AND SIDEWALK AND JUST PRIOR TO THE RAINY SEASON TO ALLOW MAXIMUM GROWTH OF HYDROSEEDED AREA. GENERAL: 1. A CONSTRUCTION ENTRANCE SHALL BE INSTALLED PRIOR TO COMMENCEMENT OF GRADING. LOCATION OF THE ENTRANCE MAY BE ADJUSTED BY THE CONTRACTOR TO FACILITATE GRADING OPERATIONS. ALL CONSTRUCTION TRAFFIC ENTERING THE PAVED ROAD MUST CROSS THE CONSTRUCTION ENTRANCE. 2. CHANGES TO THIS EROSION AND SEDIMENT CONTROL PLAN TO MEET FIELD CONDITIONS SHALL BE MADE ONLY WITH THE APPROVAL OF, OR AT THE DIRECTION OF THE CITY ENGINEER. DURING THE RAINY SEASON, PUBLIC ROADWAY SHALL BE KEPT CLEAR OF EARTH MATERIAL AND DEBRIS. THE SITE SHALL BE MAINTAINED SO THAT A MINIMUM OF SEDIMENT LADEN RUNOFF ENTERS THE STORM DRAINAGE SYSTEM AND PUBLIC ROADWAY. THIS PLAN COVERS ONLY THE FIRST WINTER FOLLOWING GRADING. PLANS SHALL BE RESUBMITTED FOR APPROVAL PRIOR TO SEPTEMBER IST OF EACH SUBSEQUENT YEAR UNTIL THE PROPOSED IMPROVEMENTS ARE COMPLETED. 3. CONTROL MEASURES SHALL BE INSPECTED AND REPAIRED AT THE END OF EACH WORKING DAY AND, IN ADDITION, AFTER EACH STORM. 0 10, INSTALL STRAW ROLL AND AT BACK OF WALK O Z INSTALL GRAVEL BAGS AND FILTER FABRICS OO Q TO PROTECT ALL INLETS OO OO J CL (TYP ALL INLETS) F— INSTALL CONSTRUCTION ENTRANCE PROTECTION O C z CONTRACTOR TO STABILIZE THROUGH HYDROSEEDING W MLd DISTURBED SOIL PRIOR TO RAINY SEASON INSTALL CONCRETE WASHOUT AREA IN EL LOCATIONS APPROVED BY A CERTIFIED PROFESSIONAL O IN EROSION & SEDIMENT CONTROL J INSTALL EQUIPMENT REFUEL AND SERVICE AREA IN _ LOCATIONS APPROVED BY A CERTIFIED PROFESSIONAL - IN EROSION & SEDIMENT CONTROL M GENERAL: 1.
