TESC NOTES
1. ESC MINIMUM REQUIREMENT -CONSTRUCTION ACCESS ROUT, CONSTRUCTION VEHICLE ACCESS SHALL
BE, WHENEVER PRACTICAL, LIMITED TO ONE ROUTE. ACCESS POINTS SHALL BE STABILIZED WITH
QUARRY SPALLS OR CRUSHED ROCK TO MINIMIZE THE TRACKING OF SEDIMENT ONTO PUBLIC ROADS.
IF SEDIMENT IS TRANSPORTED ONTO A ROAD SURFACE, THE ROADS SHALL BE CLEANED
THOROUGHLY AT THE END OF EACH DAY. SEDIMENT SHALL BE REMOVED FROM ROADS BY
SHOVELING OR SWEEPING AND BE TRANSPORTED TO A CONTROLLED SEDIMENT DISPOSAL AREA
WITHIN 24 HOURS. STREET WASHING SHALL BE ALLOWED ONLY AFTER SEDIMENT IS REMOVED /N
THIS MANNER.
2. ESC MINIMUM REQUIREMENT -STABILIZATION OF EXPOSED AREAS. ALL SOILS EXPOSED BY LAND
DISTURBING ACTIVITIES SHALL BE STABILIZED BY SUITABLE APPLICATION OF BMPS, INCLUDING, BUT
NOT LIMITED, SOD, HYDROSEED/NG, OR OTHER VEGETATION, PLASTIC COVERING, OR MULCHING. ALL
BMPS SHALL BE SELECTED, DESIGNED, AND MAINTAINED /N ACCORDANCE WITH THE MANUAL. THE
EXPOSED SOILS SHALL BE STABILIZED ACCORDING TO AN APPROVED TIMETABLE. (TYPICALLY, NO

SEDIMENT CONTROL BMPS SHALL BE REMOVED WITHIN 30 DAYS AFTER FINAL SITE STABILIZATION IS
ACHIEVED OR AFTER THE TEMPORARY BMPS ARE NO LONGER NEEDED. TRAPPED SEDIMENT SHALL
BE REMOVED OR STABILIZED ON SITE. DISTURBED SOIL AREAS RESULTING FROM REMOVAL SHALL BE
PERMANENTLY STABILIZED.
15. EROSION AND SEDIMENT CONTROL REQUIREMENT-DEWATER/NG CONSTRUCTION SITES. DEWATER/NG
SYSTEMS SHALL DISCHARGE INTO A SEDIMENT TRAP OR SEDIMENT POND.
16. EROSION AND SEDIMENT CONTROL REQUIREMENT -CONTROL OF POLLUTANTS OTHER THAN SEDIMENT
ON CONSTRUCTION SITES. ALL POLLUTANTS OTHER THAN SEDIMENT THAT OCCUR ON SITE DURING
CONSTRUCTION SHALL BE HANDLED AND DISPOSED OF /N A MANNER THAT DOES NOT CAUSE
CONTAMINATION OF STORM WATER.
17. EROSION AND SEDIMENT CONTROL REQUIREMENT -FINANCIAL L/ABILITY. PERFORMANCE BONDING, OR
OTHER APPROPRIATE FINANCIAL INSTRUMENTS, SHALL BE REQUIRED FOR ALL PROJECTS TO ENSURE
COMPLIANCE WITH THE APPROVED EROSION AND SEDIMENT CONTROL PLAN. [ORD. 3013 1, 1995].
