CONSTRUCTION OF THE BIORETENTION AREA MAY ONLY BEGIN AFTER THE ENTIRE CONTRIBUTING DRAINAGE AREA HAS BEEN STABILIZED WITH VEGETATION. LL STEP 2. CONTRACTOR SHALL SCHEDULE A PRECONSTRUCTION MEETING WITH THE ENGINEER, AT WHICH TIME, THE BOUNDARIES OF THE CONTRIBUTING DRAINAGE AREA AND THE ACTUAL INLET ELEVATIONS WILL BE VERIFIED TO ENSURE THEY CONFORM TO THE DESIGN. STEP 3. TEMPORARY E&S CONTROLS SHALL BE PROVIDED AS REQUIRED DURING CONSTRUCTION OF THE BIORETENTION AREA TO DIVERT STORMWATER AWAY FROM THE BIORETENTION AREA UNTIL IT IS COMPLETED. SPECIAL PROTECTION MEASURES SUCH AS EROSION CONTROL FABRICS MAY BE NEEDED TO PROTECT VULNERABLE SIDE SLOPES FROM EROSION DURING THE CONSTRUCTION PROCESS. STEP 4. ANY PRE-TREATMENT CELLS SHALL BE EXCAVATED AND SEALED TO TRAP SEDIMENTS. STEP 5. EXCAVATORS OR BACKHOES SHALL WORK FROM THE SIDES TO EXCAVATE THE BIORETENTION AREA TO ITS APPROPRIATE DESIGN DEPTH AND DIMENSIONS. EXCAVATING EQUIPMENT SHALL HAVE SCOOPS WITH ADEQUATE REACH SO THEY DO NOT SIT INSIDE THE FOOTPRINT OF THE BIORETENTION AREA. STEP 6. RIP THE BOTTOM SOILS OF THE BIORETENTION TO A DEPTH OF 6 TO 12 INCHES TO PROMOTE GREATER INFILTRATION. STEP 7. PLACE GEOTEXTILE FABRIC ON THE SIDES OF THE BIORETENTION AREA WITH A 6-INCH OVERLAP ON THE SIDES. PLACE THE APPROPRIATE DEPTH OF #57 STONE ON THE BOTTOM, PROVIDE THE PERFORATED UNDERDRAIN PIPE, PROVIDE #57 STONE AND GEOTEXTILE OVER PIPE, AND PROVIDE CHOKER STONE LAYER. STEP 8. OBTAIN THE SOIL MEDIA FROM A QUALIFIED VENDOR, AND STORE IT ON AN ADJACENT IMPERVIOUS AREA OR PLASTIC SHEETING. AFTER VERIFYING THAT THE MEDIA MEETS THE SPECIFICATIONS, APPLY THE MEDIA IN 12-INCH LIFTS UNTIL THE DESIRED TOP ELEVATION OF THE BIORETENTION AREA IS ACHIEVED. WAIT 3-5 DAYS TO CHECK FOR SETTLEMENT, AND ADD ADDITIONAL MEDIA, AS NEEDED, TO ACHIEVE THE DESIGN ELEVATION. STEP 9. PREPARE PLANTING HOLES FOR ANY TREES AND SHRUBS, INSTALL THE VEGETATION, AND WATER ACCORDINGLY. INSTALL ANY TEMPORARY IRRIGATION. STEP 10. PROVIDE MULCH LAYER.
