<br />GENERAL NOTES:
<br />1. EROSION AND SEDIMENT CONTROL MEASURES SHALL BE EFFECTIVE FOR THE DURATION OF THE CONSTRUCTION
<br />ACTIVITY.
<br />2. NO STORM RUNOFF WATER SHALL BE ALLOWED TO DRAIN DIRECTLY INTO THE EXISTING UNDERGROUND STORM
<br />SYSTEM BEFORE THE ON-SITE STORM DRAIN SYSTEM, LANDSCAPE, AND PAVING IS INSTALLED AND COMPLETED.
<br />3. AS SOON AS IS PRACTICAL AFTER THE NEW ON-SITE STORM DRAIN SYSTEM IS INSTALLED, THE CATCH BASINS
<br />SHALL BE INSTALLED AND GRAVEL BAGS AND SCREENS SHALL BE PLACED AROUND THE CATCH BASINS, AS
<br />SHOWN. THE CONTRACTOR SHALL HAVE AN OPTION TO INSTALL PREFABRICATED STEEL FRAMES WITH FILTER
<br />SCREEN OF FILTER FABRIC ATTACHED TO THE FRONT OF THE DRAIN INLET AND EXTEND 12 INCHES (12") ON EACH
<br />SIDE OF THE DRAIN INLET OPENING. FRAME SHALL BE APPROVED BY THE COUNTY ENGINEER AND SHALL FIT THE
<br />OPENING WITH LESS THAN ONE-QUARTER INCH (1/4") GAP AT ANY ONE POINT.
<br />4. THE NAME, ADDRESS AND 24-HOUR TELEPHONE NUMBER OF THE PERSON RESPONSIBLE FOR IMPLEMENTATION OF
<br />THE EROSION AND SEDIMENTATION CONTROL PLAN SHALL BE PROVIDED.
<br />5. A MINIMUM OF 50' OF DRAIN ROCK, 4" TO 6" DIAMETER, AT A MINIMUM DEPTH OF 12", SHALL BE INSTALLED AT EACH
<br />DRIVEWAY ENTRANCE TO THE SITE. THIS DOES NOT NEED TO BE DONE AT DRIVEWAYS, WHICH WILL BE CLOSED BY
<br />IMMOVABLE BARRICADES DURING CONSTRUCTION.
<br />6. ALL EROSION AND SEDIMENTATION CONTROL MEASURES SHALL BE MAINTAINED UNTIL DISTURBED AREAS ARE
<br />STABILIZED. CHANGES TO THE EROSION AND SEDIMENTATION CONTROL PLAN SHALL BE MADE TO MEET FIELD
<br />CONDITIONS, BUT ONLY WITH THE APPROVAL OF OR AT THE DIRECTION OF THE COUNTY ENGINEER.
<br />7. ALL SIDEWALK AND PAVED AREAS SHALL BE KEPT CLEAR OF EARTH MATERIAL AND DEBRIS. THE THE SITE SHALL BE
<br />MAINTAINED SO AS TO MINIMIZE SEDIMENT LADEN RUNOFF FROM ENTERING ANY STORM DRAINAGE SYSTEM.
<br />8. THE EROSION AND SEDIMENTATION CONTROL PLAN COVERS ONLY THE FIRST WINTER DURING WHICH
<br />CONSTRUCTION IS TO TAKE PLACE. PLAN AMENDMENTS SHALL BE PREPARED BY THE PROJECT QSD AS DEEMED
<br />NECESSARY.
<br />9. IT IS THE RESPONSIBILITY OF THE CONTRACTOR TO INSPECT AND REPAIR ALL EROSION CONTROL FACILITIES AT
<br />THE END OF EACH WORK DAY.
<br />10. IT IS THE RESPONSIBILITY OF THE CONTRACTOR TO CLEAN OUT SEDIMENT BASINS WHENEVER THE LEVEL OF
<br />SEDIMENT REACHES THE MANUFACTURERS SEDIMENT CLEAN OUT LEVEL.
<br />11. IT IS THE RESPONSIBILITIES OF THE CONTRACTOR TO PROTECT TEMPORARY BORROW AREAS AND/OR STOCKPILES
<br />WITH APPROPRIATE EROSION CONTROL MEASURES.
<br />12. THE CLEANING OF PAVED STREETS, DURING AND AT THE COMPLETION OF CONSTRUCTION, SHALL BE PERFORMED
<br />WITH MECHANICAL SWEEPERS. THE USE OF WATER TRUCKS TO "WASH DOWN" THE STREET IS PROHIBITED.
<br />13. THE FOLLOWING PLANS ARE ACCURATE FOR EROSION CONTROL PURPOSES ONLY.
<br />14. THE INFORMATION ON THIS PLAN IS INTENDED TO BE USED AS A GUIDELINE FOR THE CONTRACTOR AND
<br />SUBCONTRACTORS TO COMPLY WITH THE REQUIREMENTS OF THE STATE WATER RESOURCES CONTROL BOARD.
<br />FIELD CONDITIONS MAY NECESSITATE MODIFICATIONS TO THIS PLAN.
<br />15. NO ON-SITE FUELING SHALL TAKE PLACE.
<br />16. ADDITIONAL STABILIZED CONSTRUCTION ENTRANCES MAY BE REQUIRED, OR LOCATIONS MAY BE CHANGED, AS
<br />DETERMINED BY PROJECT CONSTRUCTION STAFF.
<br />17. ANY CHANGES TO THE PROJECT SWPPP SHALL BE APPROVED BY THE PROJECT QSD PRIOR TO BEING
<br />IMPLEMENTED.
<br />18. IMPLEMENTATION OF THE RECOMMENDED EROSION CONTROL MEASURES AS SHOWN ON THESE PLANS DOES NOT
<br />ENSURE COMPLIANCE WITH FEDERAL, STATE, AND LOCAL LAWS, REGULATIONS AND ORDINANCES. THE BURDEN OF
<br />COMPLIANCE RESTS SOLELY WITH THE OWNER AND DEVELOPER OF THE PROJECT.
<br />CONCRETE WASTE MANAGEMENT NOTES
<br />CONCRETE SLURRY WASTES
<br />1. PCC AND AC WASTE SHALL NOT BE ALLOWED TO ENTER STORM DRAINS OR WATERCOURSES.
<br />2. PCC AND AC WASTE SHALL BE COLLECTED AND DISPOSED OF IN A TEMPORARY CONCRETE WASHOUT FACILITY.
<br />3. A SIGN SHALL BE INSTALLED ADJACENT TO EACH TEMPORARY CONCRETE WASHOUT FACILITY TO INFORM
<br />CONCRETE EQUIPMENT OPERATORS TO UTILIZE THE PROPER FACILITIES.
<br />4. DO NOT ALLOW SLURRY RESIDUE FROM WET CORING OR SAW -CUTTING AC OR PCC TO ENTER STORM DRAINS OR
<br />RECEIVING WATERS.
<br />5. VACUUM SLURRY RESIDUE AND DISPOSE IN A TEMPORARY PIT AND ALLOW SLURRY TO DRY. DISPOSE OF DRY
<br />SLURRY RESIDUE IN ACCORDANCE WITH BMP WM-5.
<br />6. COLLECT RESIDUE FROM GROOVING AND GRINDING OPERATIONS IN ACCORDANCE WITH STANDARD
<br />SPECIFICATIONS SECTION 42-1.02 AND 42-2.02, "CONSTRUCTION."
<br />ON-SITE TEMPORARY CONCRETE WASHOUT FACILITY, TRANSIT TRUCK WASHOUT PROCEDURES
<br />1. TEMPORARY CONCRETE WASHOUT FACILITIES SHALL BE LOCATED A MINIMUM OF 50 FT FROM STORM DRAIN
<br />INLETS, OPEN DRAINAGE FACILITIES, AND WATERCOURSES, UNLESS DETERMINED UNFEASIBLE BY THE
<br />ENGINEER. EACH FACILITY SHALL BE LOCATED AWAY FROM CONSTRUCTION TRAFFIC OR ACCESS AREAS TO
<br />PREVENT DISTURBANCE OR TRACKING.
<br />2. A SIGN SHALL BE INSTALLED ADJACENT TO EACH WASHOUT FACILITY TO INFORM CONCRETE EQUIPMENT
<br />OPERATORS TO UTILIZE THE PROPER FACILITIES.
<br />3. TEMPORARY CONCRETE WASHOUT FACILITIES SHALL BE CONSTRUCTED ABOVE GRADE. TEMPORARY CONCRETE
<br />WASHOUT FACILITIES SHALL BE CONSTRUCTED AND MAINTAINED IN SUFFICIENT QUANTITY AND SIZE TO CONTAIN
<br />ALL LIQUID AND CONCRETE WASTE GENERATED BY WASHOUT OPERATIONS.
<br />4. TEMPORARY WASHOUT FACILITIES SHALL HAVE A TEMPORARY PIT OR BERMED AREAS OF SUFFICIENT VOLUME
<br />TO COMPLETELY CONTAIN ALL LIQUID AND WASTE CONCRETE MATERIALS GENERATED DURING WASHOUT
<br />PROCEDURES.
<br />5. PERFORM WASHOUT OF CONCRETE TRUCKS IN DESIGNATED AREAS ONLY.
<br />6. ONCE CONCRETE WASTES ARE WASHED INTO THE DESIGNATED AREA AND ALLOWED TO HARDEN, THE
<br />CONCRETE SHALL BE BROKEN UP, REMOVED, AND DISPOSED. DISPOSE OF HARDENED CONCRETE ON A REGULAR
<br />BASIS.
<br />TEMPORARY CONCRETE WASHOUT FACILITY (TYPE ABOVE GRADE)
<br />1. TEMPORARY CONCRETE WASHOUT FACILITY (TYPE ABOVE GRADE) SHALL BE CONSTRUCTED AS SHOWN ON THE
<br />PLANS, WITH A RECOMMENDED MINIMUM LENGTH AND MINIMUM WIDTH OF 10 FEET, BUT WITH SUFFICIENT
<br />QUANTITY AND VOLUME TO CONTAIN ALL LIQUID AND CONCRETE WASTE GENERATED BY WASHOUT OPERATIONS.
<br />THE LENGTH AND WIDTH OF A FACILITY MAY BE INCREASED, AT THE CONTRACTOR'S EXPENSE, UPON APPROVAL
<br />OF THE ENGINEER.
<br />2. PLASTIC LINING MATERIAL SHALL BE A MINIMUM OF 60 ML POLYETHYLENE SHEETING AND SHALL BE FREE OF
<br />HOLES, TEARS OR OTHER DEFECTS THAT COMPROMISE THE IMPERMEABILITY OF THE MATERIAL.
<br />REMOVAL OF TEMPORARY CONCRETE WASHOUT FACILITIES
<br />1. WHEN TEMPORARY CONCRETE WASHOUT FACILITIES ARE NO LONGER REQUIRED FOR THE WORK, AS
<br />DETERMINED BY THE ENGINEER, THE HARDENED CONCRETE SHALL BE REMOVED AND DISPOSED OF. MATERIALS
<br />USED TO CONSTRUCT TEMPORARY CONCRETE WASHOUT FACILITIES SHALL BECOME THE PROPERTY OF THE
<br />CONTRACTOR, SHALL BE REMOVED FROM THE SITE OF THE WORK, AND SHALL BE DISPOSED OF.
<br />2. HOLES, DEPRESSIONS OR OTHER GROUND DISTURBANCE CAUSED BY THE REMOVAL OF THE TEMPORARY
<br />CONCRETE WASHOUT FACILITIES SHALL BE BACKFILLED AND REPAIRED IN CONFORMANCE WITH THE PROJECT
<br />SPECIFICATIONS.
<br />3. THE CONTRACTOR'S WASTE POLLUTION CONTROL MANAGER (WPCM) SHALL MONITOR ON SITE CONCRETE
<br />WASTE STORAGE AND DISPOSAL PROCEDURES AT LEAST WEEKLY
<br />4. THE WPCM SHALL MONITOR CONCRETE WORKING TASKS, SUCH AS SAW CUTTING, CORING, GRINDING AND
<br />GROOVING AT LEAST WEEKLY TO ENSURE PROPER METHODS ARE EMPLOYED.
<br />5. TEMPORARY CONCRETE WASHOUT FACILITIES SHALL BE MAINTAINED TO PROVIDE ADEQUATE HOLDING
<br />CAPACITY WITH A MINIMUM FREEBOARD OF 4" FOR ABOVE GRADE FACILITIES AND 12" FOR BELOW GRADE
<br />FACILITIES. MAINTAINING TEMPORARY CONCRETE WASHOUT FACILITIES SHALL INCLUDE REMOVING AND
<br />DISPOSING OF HARDENED CONCRETE AND RETURNING THE FACILITIES TO A FUNCTIONAL CONDITION.
<br />HARDENED CONCRETE MATERIALS SHALL BE REMOVED AND DISPOSED OF IN CONFORMANCE WITH THE
<br />PROVISIONS IN SECTION 15-3.02, "REMOVAL METHODS", OF THE STANDARD SPECIFICATIONS.
<br />6. EXISTING FACILITIES MUST BE CLEANED, OR NEW FACILITIES MUST BE CONSTRUCTED AND READY FOR USE ONCE
