INSTALL ALL TEMPORARY EROSION CONTROL MEASURES (IN ACCORDANCE WITHMnDOT GENERAL CONDITIONS 2573) PRIOR TO THE START OF ANY CONSTRUCTIONOPERATION THAT MAY CAUSE ANY SEDIMENTATION OR SILTATION AT THE SITE.2. INSTALL STORM DRAIN INLET PROTECTION TO PREVENT CLOGGING OF THE STORMSEWER AND SEDIMENT LOADS TO DOWNSTREAM STORM WATER FACILITIES ORWATERBODIES.3. IF THE STORMWATER BMP IS BEING DESIGNED TO SERVE AS A TEMPORARYSEDIMENT BASIN, GRADE THE BMP TO WITHIN THREE (3) FEET OF FINAL GRADE TOPROTECT THE UNDERLYING MATERIAL FROM CLOGGING. ONCE CONSTRUCTION INTHE CONTRIBUTING DRAINAGE AREA HAS BEEN COMPLETED AND THE SITE ISSTABILIZED, EXCAVATE THE INFILTRATION BASIN TO FINAL GRADE AND COMPLETECONSTRUCTION OF THE BMP.4. GRADING OF THE INFILTRATION BASIN SHALL BE ACCOMPLISHED USINGLOW-IMPACT EARTH-MOVING EQUIPMENT TO PREVENT COMPACTION OF THEUNDERLYING SOILS. SMALL TRACKED DOZERS AND BOBCATS WITH RUNNERTRACKS ARE RECOMMENDED.5. EXCAVATE THE INFILTRATION BASIN TO THE SPECIFIED DEPTH (ELEVATION). IT ISRECOMMENDED THAT ALL SUB MATERIAL BELOW THE SPECIFIED ELEVATIONSHALL BE LEFT UNDISTURBED, UNLESS OTHERWISE DIRECTED BY THE ENGINEER.6. GRADE TO THE DEPTH (ELEVATION) SPECIFIED IN THE CONSTRUCTIONDOCUMENTS UNLESS OTHERWISE DIRECTED BY THE ENGINEER.7. IN THE EVENT THAT SEDIMENT IS INTRODUCED INTO THE BMP DURING ORIMMEDIATELY FOLLOWING EXCAVATION, THIS MATERIAL WILL NEED TO BEREMOVED FROM THE BASIN PRIOR TO INITIATING THE NEXT STEP IN THECONSTRUCTION PROCESS. SEDIMENT THAT HAS BEEN WASHED INTO THE BASINDURING THE EXCAVATION PROCESS CAN SEAL THE PERMEABLE MATERIAL,SIGNIFICANTLY REDUCING THE INFILTRATION CAPACITY OF THE SOILS.8. SEEDING AND INSTALLATION OF EROSION CONTROL BLANKET SHALL BECOMPLETED WITHIN 48 HOURS OF FINAL GRADING.9. INFILTRATION AREA SHALL BE STAKED OFF DURING CONSTRUCTION TO RESTRICTHEAVY EQUIPEMENT TRAFFIC FROM COMPACTING NATIVE SOILS.CONSTRUCTION SEQUENCING:1. PERFORM CONTINUOUS INSPECTIONS OF EROSIONCONTROL PRACTICES.2. INSTALL SILT FENCE ALONG THE PERIMETER OF THE SITETO PREVENT SEDIMENT FROM LEAVING THE SITE DURINGTHE CONSTRUCTION PROCESS.3. ALL DOWNGRADIENT PERIMETER SEDIMENT-CONTROLBMPS MUST BE IN PLACE BEFORE ANY UP GRADIENTLAND-DISTURBING ACTIVITY BEGINS.4. REMOVE TOPSOIL FROM THE SITE AND PLACE INTEMPORARY STOCKPILE LOCATION.
