EVERETT 7-ELEVEN SITE DEVELOPMENT <br />A PORTION OF THE NW 1/4 OF THE SW 1/4 AND THE SW 1/4 OF THE NW 1/4 OF SEC. 12, TWN. 28 N., RGE. 04 E. W.M. <br />CITY OF EVERETT, SNOHOMISH COUNTY, WASHINGTON. <br />T.E.S.C. NOTES <br />1. APPROVAL OF THIS EROSION/SEDIMENTATION CONTROL (ESC) <br />PLAN DOES NOT CONSTITUTE AN APPROVAL OFPERMANENT <br />ROAD OR DRAINAGE DESIGN (E.G. SIZE AND LOCATION OF ROADS, <br />PIPES, RESTRICTORS, CHANNELS, RETENTION FACILITIES, <br />UTILITIES). <br />2. THE IMPLEMENTATION OF THESE ESC PLANS AND THE <br />CONSTRUCTION, MAINTENANCE, REPLACEMENT, AND UPGRADING <br />OF THESE ESC FACILITIES IS THE RESPONSIBILITY OF THE <br />APPLICANT/CONTRACTOR UNTIL ALL CONSTRUCTION IS <br />COMPLETED AND APPROVED AND VEGETATION/LANDSCAPING IS <br />ESTABLISHED. <br />3. THE BOUNDARIES OF THE CLEARING LIMITS SHOWN ON THIS PLAN <br />SHALL BE CLEARLY FLAGGED IN THE FIELD PRIOR TO <br />CONSTRUCTION. DURING THE CONSTRUCTION PERIOD, NO <br />DISTURBANCE BEYOND THE FLAGGED CLEARING LIMITS SHALL BE <br />PERMITTED. THE FLAGGING SHALL BE MAINTAINED BY THE <br />APPLICANT/CONTRACTOR FOR THE DURATION OF <br />CONSTRUCTION. <br />4. THE ESC FACILITIES SHOWN ON THIS PLAN MUST BE <br />CONSTRUCTED IN CONJUNCTION WITH ALL CLEARING AND <br />GRADING ACTIVITIES, AND IN SUCH A MANNER AS TO ENSURE <br />THAT SEDIMENT AND SEDIMENT LADEN WATER DO NOT ENTER <br />THE DRAINAGE SYSTEM, ROADWAYS, OR VIOLATE APPLICABLE <br />WATER QUALITY STANDARDS. <br />5. THE ESC FACILITIES SHOWN ON THIS PLAN ARE THE MINIMUM <br />REQUIREMENTS FOR ANTICIPATED SITE CONDITIONS. DURING <br />THE CONSTRUCTION PERIOD, THESE ESC FACILITIES SHALL BE <br />UPGRADED AS NEEDED FOR UNEXPECTED STORM EVENTS AND <br />TO ENSURE THAT SEDIMENT AND SEDIMENT -LADEN WATER DO <br />NOT LEAVE THE SITE. <br />6. THE ESC FACILITIES SHALL BE INSPECTED ROUTINELY AND <br />MAINTAINED BY THE APPLICANT/CONTRACTOR TO ENSURE THEIR <br />CONTINUED FUNCTIONING, ESPECIALLY AFTER STORM EVENTS. <br />7. THE ESC FACILITIES ON INACTIVE SITES SHALL BE INSPECTED <br />AND MAINTAINED A MINIMUM OF ONCE A MONTH OR WITHIN THE <br />48 HOURS FOLLOWING A MAJOR STORM EVENT. <br />8. AT NO TIME SHALL MORE THAN ONE FOOT OF SEDIMENT BE <br />ALLOWED TO ACCUMULATE WITHIN A TRAPPED CATCH BASIN. ALL <br />CATCH BASINS AND CONVEYANCE LINES SHALL BE CLEANED <br />PRIOR TO PAVING. THE CLEANING OPERATION SHALL NOT FLUSH <br />SEDIMENT LADEN WATER INTO THE DOWNSTREAM SYSTEM. <br />9. STABILIZED CONSTRUCTION ENTRANCES SHALL BE INSTALLED AT <br />THE BEGINNING OF CONSTRUCTION AND MAINTAINED FOR THE <br />DURATION OF THE PROJECT. ADDITIONAL MEASURES MAY BE <br />REQUIRED TO ENSURE THAT ALL PAVED AREAS ARE KEPT CLEAN <br />FOR THE DURATION OF THE PROJECT. <br />10. THE CONTRACTOR SHALL PROVIDE PERIODIC STREET CLEANING <br />TO REMOVE DEBRIS AND SEDIMENT TRACKED OFF THE SITE. <br />11. APPROPRIATE MEASURES SHALL BE TAKEN TO STOP SEDIMENT <br />FROM ENTERING SURFACE WATER BODIES IF THE PROPOSED <br />BMPS FAIL. <br />12. BARE AND/OR DISTURBED SOILS SHALL REMAIN UNCOVERED <br />AND/OR UNSTABILIZED FOR NO MORE THAN 2 DAYS FROM <br />OCTOBER 1 THROUGH APRIL 30, AND FOR NO MORE THAN 7 DAYS <br />FROM MAY 1 THROUGH SEPTEMBER 30. <br />Oo <br />Iw what's below. <br />Call before you dig. <br />HYDROSEEDING NOTES <br />1. HYDROSEEDING SHALL BE APPLIED IN ACCORDANCE WITH THE'T.E.S.C. NOTES" ON THIS <br />SHEET. <br />2.

SEED BEDS PLANTED BETWEEN MAY 1 AND AUGUST 31 WILL REQUIRE IRRIGATION AND OTHER <br />MAINTENANCE AS NECESSARY TO FOSTER AND PROTECT THE ROOT STRUCTURE. <br />6. FOR SEED BEDS PLANTED BETWEEN OCTOBER 31 AND APRIL 30, ARMORING OF THE SEED BED <br />WILL BE NECESSARY. (E.G., GEOTEXTILES, JUTE MAT, CLEAR PLASTIC COVERING.) <br />7. BEFORE SEEDING, INSTALL NEEDED SURFACE RUNOFF CONTROL MEASURES SUCH AS <br />GRADIENT TERRACES, INTERCEPTOR DIKES, SWALES, LEVEL SPREADERS AND SEDIMENT <br />BASINS. <br />8. THE SEEDBED SHALL BE FIRM WITH A FAIRLY FINE SURFACE, FOLLOWING SURFACE <br />ROUGHENING. PERFORM ALL OPERATIONS ACROSS OR AT RIGHT ANGLES TO THE SLOPE. <br />9. FERTILIZERS ARE TO BE USED ACCORDING TO SUPPLIERS RECOMMENDATIONS. AMOUNTS <br />USED SHOULD BE MINIMIZED, ESPECIALLY ADJACENT TO WATER BODIES AND WETLANDS. <br />10.
