IF THE FABRIC ON A SILT FENCE OR FILTER BARRIER DECOMPOSES OR BECOMESINEFFECTIVE PRIOR TO THE END OF THE EXPECTED USABLE LIFE AND THE BARRIER ISSTILL NECESSARY, THE FABRIC SHALL BE REPLACED PROMPTLY.

SEDIMENT DEPOSITS REMAINING IN PLACE AFTER THE SILT FENCE OR FILTER BARRIERIS REMOVED SHALL BE DRESSED TO CONFORM WITH THE EXISTING GRADE ANDSEEDED.

TEMPORARY DIVERSION DIKE:THIS MEASURE SHALL BE INSPECTED AFTER EACH SIGNIFICANT STORM AND REPAIRSSHOULD BE MADE TO THE DIKE, FLOW CHANNEL AND OUTLET AS NECESSARY.

APPROXIMATELY ONCE EVERY WEEK, WHETHER A STORM HAS OCCURRED OR NOT,DIKES SHOULD BE INSPECTED AND REPAIRED IF NEEDED. LOOK FOR BREACHESCAUSED BY VEHICLES CROSSING THE DIKE. DAMAGES CAUSED BY CONSTRUCTIONTRAFFIC OR OTHER ACTIVITY SHALL BE REPAIRED BEFORE THE END OF EACHWORKING DAY.

CONTRACTOR SHALL MAINTAIN THE CLEANLINESS OF ALL EXISTING STREETS ANDREMOVE ALL SEDIMENTS CARRIED INTO THEM BY EROSION OF GRADED AREAS DAILYOR AS REQUIRED. FOR TYPICAL EROSION CONTROL DETAILS, SEE ATTACHED DETAILSHEET.

GENERAL NOTES:

1. BEST MANAGEMENT PRACTICES(BMPs) FOR THIS PROJECT SHALL BE IN SUBSTANTIALCOMPLIANCE AT ALL TIMES WITH THE STORM WATER POLLUTION PREVENTION PLAN(SWPPP) PREPARED FOR THE PROJECT IN ACCORDANCE WITH THE STATE WATERRESOURCES CONTROL BOARD (SWRCB) ORDER NO. 2009-0009-DWQ NATIONALPOLLUTANT DISCHARGE ELIMINATION SYSTEM (NPDES) GENERAL PERMIT NO.CAS000002.

THE EROSION CONTROL MEASURES ARE TO BE OPERABLE YEAR ROUND. BYSEPTEMBER 15, GRADING, INSTALLATION OF STORM DRAINAGE AND EROSIONCONTROL FACILITIES WILL NEED TO BE COMPLETED WITH EROSION CONTROLPLANTING ESTABLISHED BY THAT TIME. NO GRADING SHALL OCCUR BETWEENSEPTEMBER 15TH AND MAY 1ST UNLESS AUTHORIZED BY CITY OF MORGAN HILL.

STANDARD DROP INLET, UNDERGROUND DRAINAGE PIPE AND APPURTENANCESSHALL BE CONSTRUCTED PRIOR TO WINTERIZATION AND WILL REMAIN ASPERMANENT TRACT IMPROVEMENTS.

CHANGES TO THIS EROSION AND SEDIMENT CONTROL PLAN SHALL BE MADE TOMEET FIELD CONDITIONS ONLY WITH THE APPROVAL OF OR AT THE DIRECTION OFTHE CITY OF MORGAN HILL.

DURING THE RAINY SEASON, ALL PAVED AREAS SHALL BE KEPT CLEAR OF EARTHMATERIAL AND DEBRIS. THE SITE SHALL BE MAINTAINED SO AS TO MINIMIZESEDIMENT LADEN RUNOFF TO ANY STORM DRAINAGE SYSTEM.

THIS PLAN COVERS ONLY THE FIRST WINTER FOLLOWING GRADING. PLANS ARE TOBE RESUBMITTED FOR CITY APPROVAL PRIOR TO SEPTEMBER 1 OF EACHSUBSEQUENT YEAR UNTIL THE TRACT IMPROVEMENTS ARE ACCEPTED BY THECOUNTY.

SEED AND MULCH ARE TO BE PLACED ON ALL DISTURBED SLOPES STEEPER THAN 2%AND HIGHER THAN 3 FEET, ON ALL CUT AND FILL SLOPES WITHIN OR ADJACENT TOALL PUBLIC RIGHTS OF WAY AND AS DIRECTED BY THE CITY. SEED PLACED BETWEENMAY AND SEPTEMBER SHALL BE IRRIGATED AS NECESSARY TO ESTABLISH GROWTHBY OCTOBER 1.
