HEREBY REFERRED TO AS THE CITY, THE APPLICANT, AND THE APPLICANT'S
CONTRACTOR .
2. THE APPLICANT IS RESPONSIBLE FOR OBTAINING THE WASHINGTON STATE
DEPARTMENT OF ECOLOGY (ECOLOGY) CONSTRUCTION STORMWATER GENERAL
PERMIT, IF IT IS REQUIRED FOR THE PROJECT. THE APPLICANT SHALL PROVIDE THE
CITY COPIES OF ALL MONITORING REPORTS PROVIDED TO ECOLOGY ASSOCIATED
WITH THE CONSTRUCTION STORMWATER GENERAL PERMIT.
3. THE ESC PLAN SET SHALL INCLUDE AN ESC CONSTRUCTION SEQUENCE DETAILING
THE ORDERED STEPS THAT SHALL BE FOLLOWED FROM CONSTRUCTION
COMMENCEMENT TO POST -PROJECT CLEANUP IN ORDER TO FULFILL PROJECT ESC
REQUIREMENTS.
4. THE BOUNDARIES OF THE CLEARING LIMITS, SENSITIVE AREAS AND THEIR
BUFFERS, AND AREAS OF VEGETATION PRESERVATION AND TREE RETENTION AS
PRESCRIBED ON THE PLAN(S) SHALL BE CLEARLY DELINEATED BY FENCING AND
PROTECTED IN THE FIELD IN ACCORDANCE WITH APPENDIX D OF THE CITY OF
RENTON SURFACE WATER DESIGN MANUAL (RENTON SWDM) PRIOR TO THE START

MAINTAINED BY THE APPLICANT/ESC SUPERVISOR FOR THE DURATION OF
CONSTRUCTION.
5. STABILIZED CONSTRUCTION ENTRANCES SHALL BE INSTALLED AT THE BEGINNING
OF CONSTRUCTION AND MAINTAINED FOR THE DURATION OF THE PROJECT.
ADDITIONAL MEASURES, SUCH AS CONSTRUCTED WHEEL WASH SYSTEMS OR WASH
PADS, MAY BE REQUIRED TO ENSURE THAT ALL PAVED AREAS ARE KEPT CLEAN
AND TRACK -OUT TO ROAD RIGHT OF WAY DOES NOT OCCUR FOR THE DURATION
OF THE PROJECT. IF SEDIMENT IS TRACKED OFFSITE, PUBLIC ROADS SHALL BE
CLEANED THOROUGHLY AT THE END OF EACH DAY, OR MORE FREQUENTLY DURING
WET WEATHER, AS NECESSARY TO PREVENT SEDIMENT FROM ENTERING WATERS OF
THE STATE.
6. WASHOUT FROM CONCRETE TRUCKS SHALL BE PERFORMED OFF -SITE OR IN

ALL ESC BMPS SHALL BE MAINTAINED IN A SATISFACTORY CONDITION UNTIL SUCH
TIME THAT CLEARING AND/OR CONSTRUCTION IS COMPLETE AND POTENTIAL FOR
ON -SITE EROSION HAS PASSED. ALL ESC BMPS SHALL BE REMOVED AFTER
CONSTRUCTION IS COMPLETED AND THE SITE HAS BEEN STABILIZED TO ENSURE

8. ANY HAZARDOUS MATERIALS OR LIQUID PRODUCTS THAT HAVE THE POTENTIAL TO
POLLUTE RUNOFF SHALL BE DISPOSED OF PROPERLY
9. THE ESC BMPS 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 APPLICANT
SHALL ANTICIPATE THAT MORE ESC BMPS 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 THE
APPLICANT TO ADDRESS ANY NEW CONDITIONS THAT MAY BE CREATED BY THE
ACTIVITIES AND TO PROVIDE ADDITIONAL ESC BMPS, OVER AND ABOVE MINIMUM
REQUIREMENTS, AS MAY BE NEEDED, TO PROTECT ADJACENT PROPERTIES AND
WATER QUALITY OF THE RECEIVING DRAINAGE SYSTEM.
10. APPROVAL OF THIS PLAN IS FOR ESC ONLY. IT DOES NOT CONSTITUTE AN
APPROVAL OF STORM DRAINAGE DESIGN, SIZE NOR LOCATION OF PIPES,
RESTRICTORS, CHANNELS, OR STORMWATER FACILITIES.

ETC.) IN CONFORMANCE WITH APPENDIX D OF THE RENTON SWDM.
13. WET SEASON ESC REQUIREMENTS APPLY TO ALL CONSTRUCTION SITES BETWEEN
OCTOBER 1ST AND APRIL 30TH, UNLESS OTHERWISE APPROVED BY THE CITY.
14. ANY AREA NEEDING ADDITIONAL ESC MEASURES, NOT REQUIRING IMMEDIATE
ATTENTION, SHALL BE ADDRESSED WITHIN SEVEN (7) DAYS.
15. THE ESC BMPS ON INACTIVE SITES SHALL BE INSPECTED AND MAINTAINED AT A
MINIMUM OF ONCE A MONTH OR WITHIN 24 HOURS FOLLOWING A STORM EVENT.
INSPECTION AND MAINTENANCE SHALL OCCUR MORE FREQUENTLY AS REQUIRED BY

FUNCTIONING CONDITION. ALL DISTURBED AREAS OF THE PROJECT SITE SHALL BE
VEGETATED OR OTHERWISE PERMANENTLY STABILIZED. AT A MINIMUM, DISTURBED
AREAS SHALL BE SODDED OR SEEDED AND MULCHED TO ENSURE THAT SUFFICIENT
COVER WILL DEVELOP SHORTLY AFTER FINAL APPROVAL MULCH WITHOUT SEEDING
IS ADEQUATE FOR AREAS TO BE LANDSCAPED BEFORE OCTOBER 1ST.

APPROVAL OF THE PAVEMENT. COMPLIANCE MAY BE CHECKED USING A SIMPLE BUCKET
TEST IN WHICH 5 GALLONS OF WATER IS POURED ONTO THE PAVEMENT SURFACE ALL
AT ONCE. IF ONLY A MINOR AMOUNT OF WATER PONDS OR RUNS OFF THE SURFACE,
THEN THE PAVEMENT IS CONSIDERED TO MEET THE MINIMUM RATE OF ABSORPTION. AT
LEAST ONE TEST SHALL BE CONDUCTED PER 1,000 SQUARE FEET OF PERMEABLE
PAVEMENT. IF THIS TEST IS NOT CONCLUSIVE, THEN ANOTHER TEST PER ASTM C1701
SHALL BE CONDUCTED. FOR LARGE AREAS (E.G., PARKING AREAS), TESTING
OBSERVATION MAY BE ACCOMPLISHED WHILE WALKING BEHIND A SLOWLY MOVING WATER
TRUCK DISCHARGING WATER AT A RATE SIMILAR TO THE BUCKET TEST. PERMEABLE
PAVERS SHALL
