4. ALL REQUIRED SEDIMENTATION/EROSION CONTROL FACILITIES MUST BE CONSTRUCTED AND
IN OPERATION PRIOR TO LAND CLEARING AND/OR CONSTRUCTION TO PREVENT
TRANSPORTATION OF SEDIMENT TO SURFACE WATER, DRAINAGE SYSTEMS AND ADJACENT
PROPERTIES. ALL EROSION AND SEDIMENT FACILITIES SHALL BE MAINTAINED IN A
SATISFACTORY CONDrrION UNTIL SUCH TIME THAT CLEARING ANO/OR CONSTRUCTION IS

OTHERVASE APPROVED BY THE CITY THROUGH AN ADJUSTMENT PROCESS.
9. COWER MEASURES WILL BE APPLIED IN CONFORMANCE WITH APPENDIX D OF THE
SURFACE WAITER DESIGN MANUAL.
10. ANY AREA NEEDING ESC MEASURES, NOT REQUIRING IMMEDIATE ATTENTION, SHALL BE
ADDRESSED WITHIN SEVEN (7) DAYS.
11. THE ESC FACILITIES ON INACTIVE SITES SHALL BE INSPECTED AND MAINTAINED A MINNAUM
OF ONCE A MONTH OR WITHIN 24 HOURS FOLLOWING A STORM EVENT.
12. AT NO TIME SHALL MORE THAN ONE (1) FOOT OF SEDIMENT BE ALLOWED TO
ACCUMULATE WITHIN A CATCH BASIN. ALL CATCH BASINS AND CONVEYANCE LINES SHALL
BE CLEANED PRIOR TO PAVMNG. THE CLEANING OPERATION SHALL NOT FLUSH
SEDIMENT -UDEN WATER INTO THE DOWNSTREAM SYSTEM.
13. DURING THE TIME PERIOD OF OCTOBER 1ST THROUGH MARCH 30TH ALL PROJECT
DI ED SOIL AREAS GREATER THAN 5000 SQUARE FEET, THAT ARE TO BE LEFT
UN -WORKED FOR MORE THAN 12 HOURS, SHALL BE COVERED BY MULCH, SODDING OR
PLASTIC COVERING.
14. ANY PERMANENT RETENTION/DETENTION FACILITY USED AS A TEMPORARY SETTLING BASIN
SMALL. BE MODIFIED WITH THE NECESSARY EROSION CONTROL MEASURES AND SHALL
PROVIDE ADEQUATE STORAGE CAPACITY. IF THE PERMINEMT FACILITY IS TO FUNCTION
ULT"AT'ELY AS AN INFILTRATION SYSTEM, THE TEMPORARY FACILITY MUST BE ROUGH
GRADED SO THAT THE BOTTOM AND SIDES ARE AT LEAST THREE FEET ABOVE THE FINAL
GRADE OF THE PERMANENT FACILITY.
15. PRK)R TO THE BEGINNING OF THE WET SEASON (OCT. 1), ALL DISTURBED AREAS SHALL
BE REVIIEWD TO IDENTIFY WHICH ONES CAN BE SEEDED IN PREPARATION FOR THE
**ITER RAINS. DISTURBED AREAS SHALL BE SEEDED WIT W ONE WEEK OF THE
BEG**#NG OF THE WET SEASON. A SKETCH MAP OF THOSE AREAS TO BE SEEDED AND
THOSE AREAS TO REMAMI UNCOVERED SHALL BE SUBMITTED TO THE CITY OF RENTON

PLANS FOR STRUCTURES SUCH AS BRAS, VAULTS, AND RETAKING WALLS REQUIRE A
SEPARATE REVIEW AND APPROVAL BY THE CITY PRIOR TO CONSTRUCTION.
2. ROCKERIES ARE CONSIDERED TO BE A METHOD OF BANK STABILIZATION AND EROSION
CONTROL. ROCKERIES SHALL NOT BE CONSTRUCTED TO SERVE AS RETANG WALLS. ALL
ROCKERIES IN CITY ROAD RIGHT-OF-WAY SHALL BE CONSTRUCTED IN ACCORDANCE WITH

2.1. HOG FUEL (WOOD BASED MULCH) MAY BE SUBSTITUTED FOR OR COMBINED WITH QUARRY SPALLS IN ARES THAT WILL BOT BE USED
FOR PERMANENT ROADS. HOG FUEL IS NOT RECOMMENDED FOR ENTRANCE STABILIZATION IN URBAN AREAS. THE INSPECTOR MAY
AT ANY TIME REQUIRE THE USE OF QUARRY SPALLS IF THE HOG FUEL IS NOT PREVENTING SEDIMENT FROM BEING TRACKED ONTO

3. MAINTENANCE STANDARDS
3.1. QUARRY SPALLS SHALL BE ADDED IF THE PAD IS NO LONGER IN ACCORDANCE WITH THE SPECIFICATIONS.
3.2. IF THE ENTRANCE IS NOT PREVENTING SEDIMENT BEING TRACKED ONTO PAVEMENT, THEN ALTERNATIVE MEASURES TO KEEP THE
STREETS FREE OF SEDIMENT SHALL BE USED. THIS MAY INCLUDE STREET SWEEPING, AN INCREASE IN THE DIMENSIONS OF THE
ENTRANCE, OR THE INSTALLATION OF THE WHEEL WASH. IF WASHING IS USED, IT SHALL BE DONE ON AN AREA COVERED WITH
CRUSHED ROCK, AND WASHED WATER SHALL DRAIN TO A SEDIMENT TRAP OR POND.
3.3. ANY SEDIMENT THAT IS TRACKED ONTO PAVEMENT SHALL BE REMOVED IMMEDIATELY BY SWEEPING. THE SEDIMENT COLLECTED BY
SWEEPING SHALL BE REMOVED OR STABILIZED ON SITE. THE PAVEMENT SHALL NOT BE CLEANED BY WASHING DOWN THE STREET,
EXCEPT WHEN SWEEPING IS INEFFECTIVE AND THERE IS A THREAT TO PUBLIC SAFETY. IF IT NECESSARY TO WASH THE STREETS, A
SMALL SUMP MUST BE CONDUCTED. THE SEDIMENT WOULD THEN BE WASHED INTO THE SUMP WHERE IT CAN BE CONTROLLED AND
DISCHARGED APPROPRIATELY.
3.4. ANY QUARRY SPALLS THAT ARE LOOSENED FROM THE PAD AND END UP ON THE ROADWAY SHALL BE REMOVED IMMEDIATELY.
3.5. IF VEHICLES ARE ENTERING OR EXITING THE SITES AT POINTS OTHER THAN THE CONSTRUCTION ENTRANCE(S), FENCING SHALL BE
INSTALLED TO CONTROL TRAFFIC.
