APPROVAL OF THIS EROSION SEDIMENTA77ON CONTROL (TESC) PLAN DOES NOT CONSTITUTE AN APPROVAL OF PERMANENT ROAD OR DRAINAGE DESIGN (E. G. SIZE AND LOCATION OF ROADS, PIPES, RESTRICTORS CHANNELS, RETENTION FACILITIES, UTILITIES ETC.) 2. THE IMPLEMENTA71ON OF THESE TESC PLANS AND THE CONSTRUCTION, MAINTENANCE REPLACEMENT, AND UPGRADING OF THESE 7ESC FACILITIES IS THE RESPONSIBILITY OF THE APPLICANT/TESC SUPERVISOR UNTIL ALL CONSTRUCTION IS APPROVED. 3. THE BOUNDARIES OF THE CLEARING LIMITS SHOWN ON THIS PLAN SHALL BE CLEARLY FLAGGED BY A CON77N000S LENGTH OF SURVEY TAPE (OR FENCING, IF REQUIRED) PRIOR TO CONSTRUCTION. DURING THE CONSTRUCTION PERIOD, NO DISTURBANCE BEYOND THE CLEARING LIMITS SHALL BE PERMITTED. THE CLEARING LIMITS SHALL BE MAINTAINED BY THE APPLICANT /TESC SUPERVISOR FOR THE DURATION OF THE CONSTRUCTION. 4. THE 7ESC FACILITIES SHOWN ON THIS PLAN MUST BE CONSTRUCTED PRIOR TO OR IN CON✓UNC77ON WITH ALL CLEARING AND GRADING SO AS TO ENSURE THAT THE TRANSPORT OF SEDIMENT TO SURFACE WATERS, DRAINAGE SYSTEMS, AND ADJACENT PROPER7ES IS MINIMIZED. 5. THE TESC FACILITIES SHOWN ON THIS PLAN ARE THE MINIMUM REQUIREMENTS FOR ANTICIPATED SITE CONDITIONS. DURING THE CONSTRUCTION PERIOD, THESE TESC FACIL177ES SHALL BE UPGRADED AS NEEDED FOR UNEXPECTED STORM EVENTS AND MODIFIED TO ACCOUNT FOR CHANGING SI7E CONDIT70NS (E. G. ADDITIONAL SUMP PUMPS, RELOCAT70N OF DITCHES AND SILT FENCES, ETC.). 6. THE 7ESC FACILITIES SHALL BE INSPECTED DAILY BY THE APPLICANT 17ESC SUPERVISOR . AND MAINTAINED TO INSURE CONTINUED PROPER FUNCTIO NIN G WRITTEN RECORDS SHALL BE KEPT OF WEEKLY REVIEWS OF THE 7ESC FACIL177ES DURING THE WET SEASON (OCT 1 -APRIL 30) DRY SEASON MAY 1 - SEPTEMBER 30. 774 Y REVIEWS DURING THE D AND OF MON L ( ) 7. ANY AREA OF EXPOSED SOILS, INCLUDING ROADWAY EMBANKMENTS THAT WILL NOT BE DISTURBED FOR TWO (2) DAYS DURING THE WET SEASON OR SEVEN (7) DAYS DURING THE DRY SEASON SHALL BE IMMEDIATELY STABILIZED WITH THE APPROVED TESC METHODS (E.G., SEEDING, MULCHING, PLAS77C COVERING, ETC.). 8. ANY AREA NEEDING TESC MEASURES NOT REQUIRING IMMEDIATE ATTENTION, SHALL BE ADDRESSED WITHIN 15 DAYS. 9. THE TESC FACIL177ES ON INACTIVE SITES SHALL BE INSPECTED AND MAINTAINED A MINIMUM OF ONCE A MONTH OR WITHIN THE 48 HOURS FOLLOWING A STORM EVENT. 10. 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 PAVING. THE CLEANING OPERATION SHALL NOT FLUSH SEDIMENT LADEN WATER INTO THE DOWNSTREAM SYSTEM. 11. STABILIZED CONSTRUCT70N ENTRANCES AND ROADS SHALL BE INSTALLED AT THE BEGINNING OF CONSTRUCTION AND MAINTAINED FOR THE DURATION OF 774E PROJECT. ADDITIONAL MEASURES, SUCH AS WASH PADS, MAY BE REQUIRED TO INSURE 77-IAT ALL PAVED ARES ARE KEPT CLEAN FOR THE DURATION OF THE PROJECT. 12. ANY PERMANENT RE7ENT70N/DETENT70N FACILITY USED AS A TEMPORARY SETTLING BASIN SHALL BE MODIFIED WITH THE NECESSARY EROSION CONTROL MEASURES AND SHALL PROVIDE ADEQUATE STORAGE CAPACITY. IF THE PERMANENT FACILITY IS TO FUNCTION ULTIMATELY AS AN INFILTRATION SYSTEM, THE TEMPORARY FACILITY MUST BE GRADED SO THAT THE BOTTOM AND SIDES ARE AT LEAST ONE (1)FOOT ABOVE THE FINAL GRADE OF THE PERMANENT FACILITY. 13. WHERE STRAW MULCH FOR TEMPORARY EROSION CONTROL IS REQUIRED, IT SHALL BE APPLIED AT A MINIMUM THICKNESS OF 2 TO 3 INCHES. 14. PRIOR TO THE BEGINNING OF THE WET SEASON (OCT. 1), ALL DISTUEBED AREAS SHALL BE REVIEWED TO IDENTIFY WHICH ONE CAN BE SEEDED IN PREPARATION FOR THE WINTER RAINS. DISTURBED AREAS SHALL BE SEEDED WITHIN ONE 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 INSPECTOR. THE CITY. INSPECTOR CAN REQUIRE SEEDING OF ADDITIONAL AREAS IN ORDER TO PROTECT SURFACE WATERS, ADJACENT PROPERTIES, OR DRAINAGE FACILITIES. CONSTRUCTION SEQUENCE NOTES 1.
