MAIN 7v1'A A DETAILED INSTALLATION AND MAINTENANCE SCHEDULE DURING THE VAROUS PHASES OF CONSTRUCTION SHALL BE OUTLINED IN THE SWPPP BOOK. ROUGH GRADING: INSTALL CATCHBASIN INLET PROTECTION, INSTALL STRAW OR FILTER ROLLS AT BACK OF WALK 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. PAVING: INSTALL STRAW OR FILTER ROLLS AT NEW BACK OF WALK. MANTAIN PROTECTION AT CATCHBASIN, INSTALL ROCK BAGS IN GUTTER PAN. HYDROSEED OR STABILIZE WITH OTHER METHODS DISTURBED SOIL PRIOR TO WET SEASON, ALLOW FOR VEGETATION TO DEVELOP IF HYDROSEEDING. INSTALL CONSTRUCTION 4 ENTRANCE PROTECTION INSTALL CONCRETE WASHOUT AREA IN LOCATIONS APPROVED BY A CERTIFIED IN EROSION & SEDIMENT CONTROL O PROFESSIONAL INSTALL GRAVEL BAGS AND FILTER FABRICS OO TO PROTECT ALL INLETS (TYP ALL INLETS) OO CONTRACTOR TO STABILIZE DISTURBED SOIL PRIOR TO RAIN EVENT THROUGH SOIL BINDERS, ST RAW MULCH AND/OR EROSION CONTROL BLANKETS CALTRANS STD. SS -3, SS -6, SS -7 INSTALL FIBER VI MAINTAIN WHILE 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 ENGINEER. DURING THE RAINY SEASON, PUBLIC ROADWAY SHALL BE KEPT CLEAR OF EARTH MATERIA. 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 1ST 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. 4. ALL EROSION CONTROL BMPs Stall BE IN PLACE PRIOR TO ANY STORM EVENTS 5. CONTRACTOR TO USE A WATER TRUCK DURING GRADING TO MINIMIZE WIND EROSION AND REDUCE DUST 6. IN CASE DEWATERING IS NECESSARY, THE CONTRACTOR SHALL ENGAGE AN EROSION CONTROL CONTRACTOR TO PROPERLY DISPOSE OF THE WATER, DETENTION PONDS MAY BE REQUIRED FOR DEWATERING AND THEY WILL BE DESIGNED IF THE NEED ARISES. ALTERNATIVE EFFECTIVE METHODS SHALL BE IMPLEMENTED IF THE PROPOSED METHOD FAILS TO THE SATISFACTION OF THE INSPECTOR. ti L W 'S 3-15" 04KS TOP OF CONC. 20.58' FL OF CUL/ERT 13.51 60" STORM D,RA,N CONC.

ALL PLANTER AREAS TO RECEIVE STRAW AND TACKIFIER AFTER PAVING ACTIVITIES ARE COMPLETE 4. ALL DEBRIS AND SOLID WASTE TO BE STOCKPILED IN A 40 YARD DUMPSTER 5. ALL SPOIL PIES TO BE COVERED COMPLETELY WITH PLASTIC SHEETING AND SPOIL AREAS TO BE SURROUNDED WITH STRAW/FILTER ROLLS. 6. NO VEHICLES OR MACHINERY TO BE STORED, FUELED OR WASHED ON PROJECT SITE. ALL VEHICLE AND MACHINERY MAINTENANCE TO BE PERFORMED OFF—SITE, 7. ALL WATER PUMPED FROM TRENCHES OR SEDIMENT TRAP MUST PASS THROUGH A GRAVEL BAG FOR FILTRATION BEFORE IT IS DISCHARGED ON PROPERTY. 8. DURING ROUGH GRADING CONTRACTOR TO INSTALL EARTH DIKE AND STRAW/FILTER ROLLS AT PERIMETER OF THE PROPERTY TO MAINTAIN RUN—OFF ON SITE 9. IN CASE COLLOIDAL SUSPENSION NEEDS TO BE REMOVED PRIOR TO DISCHARGE, THE CONTRACTOR WILL DESIGN AND CONSTRUCT TEMPORARY HOLDING BASINS. THE DESIGN OF THE BASIN WILL BE ADDRESSED IF THE NEED ARISES, 10. ALL LANDSCAPED AREAS ARE GRADED TO DRAIN IN THE DIRECTION OF THE DRAIN INLET. REFER TO LANDSCAPING AND GRADING PLAN FOR DRAINAGE PATTERNS. EROSION CONTROL NOTES: WDID NUMBER 5S39C340352 RESPONSIBLE INDIVIDUAL MARSHALL MIDGLEY I. ALL EROSION AND SEDIMENT CONTROL MEASURES SHALL BE CONSTRUCTED AND 6. SENSITIVE AREAS AND AREAS WHERE EXISTING VEGETATION IS BEING PRESERVED MAINTAINED IN ACCORDANCE WITH THESE PLANS AND SPECIFICATIONS AND THE SHALL BE PROTECTED WITH CONSTRUCTION FENCING. SEDIMENT CONTROL BMPs CALTRANS STORM WATER QUALITY HANBOOKS, CURRENT EDITION (MARCH 2003). SHALL BE INSTALLED WHERE ACTIVE CONSTRUCTION AREAS DRAIN INTO SENSITIVE 2. EROSION CONTROL BEST MANAGEMENT PRACTICES (BMPs) SHALL BE INSTALLED AND MAINTAINED DURING THE WET SEASON (OCTOBER 15 THROUGH APRIL 30). SEDIMENT CONTROL BMPs SHALL BE INSTALLED AND MAINTAINED ALL YEAR. 3. ALL DRAINAGE INLETS IMMEDIATELY DOWNSTREAM OF THE WORK AREAS AND WITHIN THE WORK AREAS SHALL BE PROTECTED WITH SEDIMENT CONTROL AND INLET FILTER BAGS, YEAR ROUND. INLET FILTER BAGS SHALL BE REMOVED FROM THE DRAINAGE INLETS UPON ACCEPTANCE OF THE PUBLIC IMPROVEMENTS. 4. ALL STABILIZED CONSTRUCTION ACCESS LOCATIONS SHALL BE CONSTRUCTED PER ATTACHED DETAIL WHERE CONSTRUCTION TRAFFIC ENTERS OR LEAVES PAVED AREAS. THE STABILIZED ACCESS SHALL BE MAINTAINED ON A YEAR—ROUND BASIS UNTIL COMPLETION OF CONSTRUCTION 5. ALL AREAS DISTURBED DURING CONSTRUCTION, BY GRADING, TRENCHING, OR OTHER ACTIVITIES, SHALL BE PROTECTED FROM EROSION DURING THE WET SEASON (OCTOBER 15 THROUGH APRIL 30). HYDROSEED, IF UTILIZED, MUST BE PLACED BY SEPTEMBER 15. HYDROSEED PLACED DURING THE WET SEASON SHALL USE A SECONDARY EROSION PROTECTION METHOD SUCH AS EROSION CONTROL BLANKETS OR STRAW MULCH OR PRESERVED VEGETATION AREAS 7. SEDIMENT CONTROL BMPs SHALL BE PLACED ALONG THE PROJECT PERIMETER WHERE DRAINAGE LEAVES THE PROJECT. SEDIMENT CONTROL BMPs SHALL BE MAINTAINED YEAR ROUND UNTIL THE CONSTRUCTION IS COMPLETE OR THE DRAINAGE PATTERN HAS BEEN CHANGED AND NO LONGER LEAVES THE SITE. 8. THE FOLLOWING AREAS ARE TO RECEIVE HYDROSEEDING OR OTHER EROSION CONTROL: LOT FRONT YARD BEHIND SIDEWALK — THE FIRST 18 FEET OR TOP OF SLOPE (WHICHEVER IS GREATER) SIDEYARDS BEHIND THE SIDEWALK — THE FIRST 7.5 FEET OR TOP OF SLOPE (WHICHEVER IS GREATER) SLOPES — ALL SLOPES GREATER THAN 10:1 9. EROSION AND SEDIMENT CONTROL MEASURES FOR THIS PROJECT SHALL BE IN SUBSTANTIAL COMPLIANCE AT ALL TIMES WITH THE STORM WATER POLLUTION PREVENTION PLAN (SWPPP) PREPARED FOR THE PROJECT IN ACCORDANCE WITH THE STATE OF CALIFORNIA GENERAL CONSTRUCTION PERMIT. THIS PERMIT REQUIRES THAT THE SWPPP BE KEPT UP TO DATE TO REFLECT THE CHANGING SITE CONDITIONS AND THE SWPPP IS TO BE AVAILABLE ON SITE AT ALL TIMES FOR REVIEW BY STATE AND LOCAL INSPECTORS.
