THESE NOTES SHALL APPEAR FOR ALL PROJECTIS- SITE IMPROVEMENTS, SURFACE WATER UTILITY, WASTEWATER UTILITY, WATER UTILITY, AND TRANSPORTATION PLANS. 2. BEFORE ANY CONSTRUCTION OR DEVELOPMENT ACTMIY OCCURS, A PRE - CONSTRUCTION MEETING MUST BE HELD WITH THE CITY OF RENTON, PUBLIC WORKS DESIGN ENGINEER. 3. THE BOUNDARIES OF THE CLEARING LIMITS AND AREAS OF VEGETATION PRESERVATION AS PRESCRIBED ON THE PLAN(S) SHALL BE CLEARLY FLAGGED BY SURBEY TAPE OR FENCING IN THE FIELD PRIOR TO CONSTRUCTION IN ACCORDANCE WITH APPENDIX D OF THE SURFACE WATER DESIGN MANUAL AND OBSERVED DURING CONSTRUCTION. DURING THE CONSTRUCTION PERIOD, NO DISTURBANCE BEYOND THE CLEARING LIMITS SHALL BE PERMITTED. THE CLEARING LIMITS SHALL BE MAINTAINED BY THE APPLICANT /ESC SUPERVISOR FOR THE DURATION OF CONSTRUCTION. 4. STABILIZED CONSTRUCTION ENTRANCES SHALL BE INSTALLED AT THE BEGINNING OF CONSTRUCTION AND MAINTAINED FOR THE DURATION OF THE PROJECT. AODMO94L MEASURES, SUCH AS CONSTUCTED WHEEL WASH SYSTEMS OR WASH PADS, MAY BE REQUIRED TO ENSURE THAT ALL PAVED AREAS ARE KEPT CLEAN AND TRACK OUT 70 ROAD RIGHT OF WAY DOES NOT OCCUR FOR THE DURATION OF THE PROJECT. 5. ALL REQUIRED SEDIMENTATION /EROSION CONTROL FACINTIES MUST BE CONSTRUCTED AND IN OPERTAION PRIOR TO LAND CLEARING AND /OR CONSTRUCTION 70 PREVENT TRANSPORTATION OF SEDIMENT TO SURFACE WATER, DRAINAGE SYSTEMS AND ADJACENT PROPERTIES. ALL EROSION AND SEDIMENT FACILITIES SHALL BE MAINTAINED IN A SATISFACTORY CONDITION UNTIL SUCH TIME THAT CLEARING AND /OR CONSTRUCTON IS COMPLETE AND POTENTIAL FOR ON -SITE EROSION HAS PASSED. THE IMPLEMENTARON, MAINTENANCE, REPLACEMENTS AND ADDITIONS TO EROSION /SEDIMENT CONTROL SYSTEMS SHALL BE THE RESPONSIBILITY OF THE PERMITEE. 6. THE EROSION AND SEDIMENTATION CONTROL SYSTEM DEPICTED ON THIS DRAWING ARE INTENDED TO BE MINIMUM REQUIREMENTS TO MEET ANTICIPATED SITE CONDITIONS AS CONSTRUCTION PROGRESSES AND UNEXPECTED OR SEASONAL CONDITIONS DICTATE, THE PERMITEE SHALL ANTICIPATE THAT MORE EROSION AND SEDIMENTATION CONTROL FACILTES WILL BE NECESSARY TO ENSURE COMPLETE SILTATION CONTROL ON THE PROPOSED SITE DURING THE COURSE OF CONSTRUCTION, IT SHALL BE THE OBLIGATION AND RESPONSIBILITY OF ME PERMITEE TO ADDRESS ANY NEW CONDITIONS THAT MAY BE CREATED BY THE ACTIVITIES AND TO PROVIDE ADDITIONAL FACILRIES, OVER AND ABOVE THE MINIMUM REQUIREMENTS, AS MAY BE NEEDED, TO PROTECT ADL4C04T PROPERTIES AND WATER QUAUIY OF THE RECEIVING DRAINAGE SYSTEM. 7. APPROVAL OF THIS PLAN IS FOR EROSION /SEDIMENTATION CONTROL ONLY R DOES NOT CONSTITUTE AN APPROVAL OF STORM DRANAGE DESIGN, SIZE NOR LOCATION OF PIPE, RESTRICTORS CHANNELS, OR RETENTION FACILITIES. B. ANY AREAS OF EXPOSED SOILS, INCLUDING ROADWAYS EMBANKMENTS THAT WILL NOT BE DISTRUBED FOR TWO DAYS DURING THE WET SEASON (OCTOBER 1ST THROUGH MARCH 30TH ) OR SEVEN DAYS DURING THE DRY SEASON (APRIL 1ST THROUGH ZONE R-6 SEPTEMBER 30TH) SHALL BE IMMEDIATELY STABILIZED WITH THE APPROVED ESC COVER METHODS (E.G., SEEDING, MULCHING, PLASTIC COVERING, LTC.). 7931000153 9. WET SEASON SEASONAL EROSION AND SEDIMENT CONTROL REQUIREMENTS APPLY TO ALL CONSTRUCTION SITES CLEARING. BETWEEN. OCTOBER 1 AND MARCH 30 INCLUSN& UNLESS OTHERWISE APPROVED BY THE CITY THROUGH AN ADJUSTMENT PROCESS. 10. COVER MEASURES WILL BE APPLIED IN CONFORMANCE WITH APPENDIX D OF THE SURFACE WATER DESIGN MANUAL 11. ANY AREA NEEDING ESC MEASURES, NOT REQUIRING IMMEDIATE ATTENTION, SHALL BE ADDRESSED WITHIN SEVEN (7) DAYS. 12 THE ESC FACILITIES ON INACTIVE SITES SHALL BE INSPECTED AND MAINTAINED A MINIMUM OF ONCE A MONTH OR WITHIN 24 HOURS FOLLOWING A STORM EVENT. 13. AT NO TIME SHALL MORE THAN ONE (1) F00T OF SEDIMENT BE ALLOWED TO ACCUMULATE WITHIN A CATCH BASIN. ALL CATCH BA51NS AND CONVEYANCE LINES SHALL BE CLEANED PRIOR TO PAVING. THE CLEANING OPERATION SHALL NOT FLUSH SEDIMENT-LADEN WATER INTO THE DOWNSTREAM SYSTEM. 14. DURING THE TIME PERIOD OF OCTOBER 15T THROUGH MARCH 30TH, ALL PROJECTS DISTRIBUTED SOIL AREAS GREATER, THAT ARE TO BE LEFT UN -WORKED FOR MORE THAN 12 HOURS, SHALL BE COVERED BY MULCH, SODDING OR PLASTIC COVERING. 15. ANY PERMANENT RETEN170NIDETEN17ON FACILITY USED AS A TEMPORAY SET77JNG BASIN SHALL BE MODIFIED WITH THE NECESSARY EROSION CONTROL MEASURES AND SHALL PROVIDE ADEQUATE STORAGE CAPACITY IF THE PERMANENT FACILITY IS TO FUNCTION ULTIM4TELY AS AN INFILTRATION ARE AT LEAST THREE FEET ABOVE THE FINAL GRADE OF THE PERMANENT FACILTY. 16. PRIOR TO THE BEGINNING OF THE WET SEASON (OCT. 1), ALL DISIRUBED AREAS SHALL BE REVIEWED TO IDENTIFY WHICH ONES CAN BE SEEDED IN PREPARATION FOR THE WINTER RAINS DISTURBED AREAS SHALL BE SEEDED WITHIN ON WEEK OF THE BEGINNING OF THE WET SEASON. A SKETCH MAP OF THOSE AREAS TO BE SEEDED AND THOSE AREAS TO REMAIN UNCOVERED SHALL BE SUBMITTED TO THE CITY OF RENTON FOR REVIEW. 17. THE SOIL MOISTURE HOLDING CAPACITY OF ALL NEW PERVIOUS SURFACE THAT A PROJECT COMPLETION WILL NOT BE COVERED BY IMPERVIOUS SURFACE OR INCORPORATED INTO A DRAINAGE FACILITY MUST BE PROTECTED. THE DUFF LAYER AND NATIVE TOPSOIL SHALL BE RETAINED IN AN UNDISTURBED STATE TO THE MAXIMUM EXTENT FEASIBLE. 18. ANY DUFF LAYER OR TOPSOIL REMOVED DURING GRADING SHALL BE STOCK PAID ONSI7E IN A DESIGNATED, CONTROLLED AREA NOT ADJACENT TO PUBLIC RESOURCES AND CRITICAL AREAS. THE MATERIAL SHALL BE REAPPLIED TO OTHER POR17ONS OF THE SITE WHERE FEASIBLE 19. THE SOIL IN ANY AREA THAT HAS BEEN COMPACTED OR THAT HAS HAD SOME OR ALL 20. DUST CONTROL MEASURES SHALL BE APPLIED TO PROJECT SITE STRUCTURAL NOTES 1. THESE PLANS ARE APPROVED FOR STANDARD ROAD AND DRAINAGE IMPROVEMENTS ONLY. PLANS FOR STRUCTURES SUCH AS BRIDGES, VAULTS, AND RETAINING WALLS REQUIRE A SEPARATE REVIEW AND APPROVAL BY THE CITY PRIOR TO CONSTRUCTION. 2. ROCKERIES ARE CONSIDERED TO BE A METHOD OF HANK STABILIZATION AND EROSION CONTROL ROCKERIES SFWl NOT BE CONSTRUCTED TO SERVE AS RETAINING WALLS. ALL ROCKERIES IN CITY ROAD RIGHT-OF -WAY SHALL BE CONSTRUCTED IN ACCORDANCE WITH CITY STANDARDS.
