FILTRATION AREA LIMITS SHALL BE SURVEYED AND A VISUAL BARRIER, SUCH AS ORANGE SNOW FENCE, SHALL BEPLACED AROUND THE FULL PERIMETER TO KEEP ALL CONSTRUCTION TRAFFIC, EQUIPMENT AND MATERIAL STOCKPILESOUT OF THE PROPOSED FILTRATION AREA. THE VISUAL BARRIER MUST BE INSTALLED BEFORE NEW CONSTRUCTIONBEGINS AND SHALL BE MAINTAINED THROUGH THE DURATION OF THE PROJECT.2. DELIVER SAMPLE MATERIALS ONSITE FOR PRIOR APPROVAL. PRIOR TO BEGINNING THE INSTALLATION, SUFFICIENTMATERIAL QUANTITIES SHALL BE ONSITE TO COMPLETE THE INSTALLATION AND STABILIZE EXPOSED SOIL AREASWITHOUT DELAY.3. CARE MUST BE TAKEN TO AVOID CONTAMINATION OF ENGINEERED SOILS WITH SEDIMENT, IN-SITU OR TOPSOIL DURINGAND AFTER INSTALLATION. MATERIALS MUST BE SEGREGATED.4. INSTALLATION WITH DRY SOIL CONDITIONS IS CRITICAL TO PREVENT SMEARING AND COMPACTION. SCHEDULE WORKFOR PERIODS OF DRY WEATHER. DO NOT WORK IF SOIL CONDITIONS ARE WET. EXCAVATION, SOIL PLACEMENT ANDRAPID STABILIZATION OF PERIMETER SLOPES WITH TURF SOD MUST COMPLETED BEFORE THE NEXT PRECIPITATIONEVENT. TURF SOD PLACED IN FLOW PATHS SHALL BE SECURED WITH AT LEAST 6 STAKES PER SQUARE YARD. PLACESTAKES ALONG UPHILL SEAM EDGES TO PREVENT UNDERMINING FLOWS UNTIL SOD ROOTS ESTABLISH.5. DO NOT LEAVE STORMWATER AREAS AND / OR PERIMETER SLOPES EXPOSED OVERNIGHT. SECURE THE SITE FROM RISKOF PRECIPITATION DAMAGES AT THE END OF EVERY WORK DAY. IN THE EVENT OF RAIN, TAKE ACTION TO DIVERTSTORMWATER AWAY FROM THE WORK AREA AND TEMPORARILY COVER OF ALL EXPOSED SOILS WITH FILTER FABRICOR IMPERMEABLE SHEETING.6. FIELD OBSERVATION OF EXCAVATION AND SOIL PLACEMENT IS REQUIRED. NOTIFY GEOTECHNICAL ENGINEER PRIOR TODIGGING. USE BACKHOE WITH TOOTH BUCKET FOR CELL EXCAVATION TO AVOID COMPACTING OR SMEARING OF SOILS.(DO NOT USE SKID STEER FOR EXCAVATION WITHIN THE CELL) USE TOOTH BUCKET TO SCARIFY (RIP) UNDERLYINGSOILS 6" TO 9" DEEP TO REMOVE COMPACTION. GENTLY MIX THE FIRST LIFT OF ENGINEERED SOILS WITH THE LOOSENEDUNDERLYING SOILS TO AVOID STRATIFICATION AND PROMOTE PERMEABILITY. USE EXCAVATOR BUCKET TO PLACEMATERIALS. CONSTRUCTION EQUIPMENT SHALL NOT BE ALLOWED INTO THE STORMWATER AREAS. LEVELING ANDFINAL GRADING WITHIN THE CELL MUST BE COMPLETED BY HAND.7.

THE ENGINEERED SOILSHALL NOT CONTAIN ANY TOPSOIL OR FILTER AGGREGATE WITH FINES.8. INSTALL PLANTINGS BY HAND.9. INSTALLED SOD AND PLANTINGS REQUIRE A TOTAL OF 1" OF WATER PER WEEK AND ACTIVE WEED MANAGEMENT UNTILWELL ESTABLISHED. WATERING COSTS ARE CONSIDERED INCIDENTAL TO SOD AND PLANTING INSTALLATION.CONSTRUCT A TEMPORARY IRRIGATION SYSTEM, CONSISTING OF ABOVE GROUND HEADS, PIPING, VALVES, ETC., FORWATERING UNTIL VEGETATION IS ESTABLISHED. DO NOT USE A WATER TRUCK AS THE FORCE OF THE WATER WILLADVERSELY AFFECT THE STORMWATER AREA SOILS.10.
