KING COUNTY EROSION / SEDIMENTATION CONTROL NOTES:
1. THE IMPLEMENTATION OF THESE EROSION & SEDIMENTATION
CONTROL PLANS AND THE CONSTRUCTION, MAINTENANCE,
REPLACEMENT AND UPGRADING OF THESE EROSION &
SEDIMENTATION CONTROL FACILITIES IS THE RESPONSIBILITY OF
THE CONTRACTOR UNTIL ALL CONSTRUCTION IS APPROVED.
2. THE BOUNDARIES OF THE CLEARING LIMITS SHOWN ON THIS PLAN
SHALL BE CLEARLY FLAGGED IN THE FIELD PRIOR TO
CONSTRUCTION. DURING THE CONSTRUCTION PERIOD, NO

PERMITTED. THE FLAGGING SHALL BE MAINTAINED BY THE
CONTRACTOR UNTIL DIRECTED BY THE ENGINEER TO BE
REMOVED.
3. THE EROSION & SEDIMENTATION CONTROL FACILITIES SHOWN ON
THIS PLAN MUST BE CONSTRUCTED IN CONJUNCTION WITH ALL
CLEARING AND GRADING ACTIVITIES, AND IN SUCH A MANNER AS
TO INSURE THAT SEDIMENT LADEN WATER DOES NOT ENTER THE
DRAINAGE SYSTEM OR VIOLATE APPLICABLE WATER STANDARDS.
(KCC 9,04.020 AA, KCRS 7.09 D)
4. THE EROSION & SEDIMENTATION CONTROL FACILITIES SHOWN ON
THIS PLAN ARE THE MINIMUM REQUIREMENTS FOR ANTICIPATED
SITE CONDITIONS. DURING THE CONSTRUCTION PERIOD, THESE
EROSION & SEDIMENTATION CONTROL FACILITIES SHALL BE
UPGRADED (E.G. ADDITIONAL SUMPS, RELOCATION OF DITCHES
AND SILT FENCES, ETC.) AS NEEDED FOR UNEXPECTED STORM
EVENTS (KCC 9.04.090 132).
5. THE EROSION & SEDIMENTATION CONTROL FACILITIES SHALL BE

ETC.)(KCRS 7.09D).
7. ANY AREA NEEDING EROSION & SEDIMENTATION CONTROL
MEASURE, NOT REQUIRING IMMEDIATE ATTENTION. SHALL BE

LADEN WATER INTO THE DOWNSTREAM SYSTEM.
10. DURING THE TIME PERIOD OF NOVEMBER 1 THROUGH MARCH 31,
ALL PROJECT DISTURBED AREAS GREATER THAN 5,000 SQUARE
FEET THAT ARE TO BE LEFT UNWORKED FOR MORE THAN 12

11. ANY PERMANENT RETENTION/DETENTION 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 OR DISPERSION
SYSTEM, THE FACILITY SHALL NOT BE USED AS A TEMPORARY
SETTLING BASIN. NO UNDERGROUND DETENTION TANKS OR
VAULTS SHALL BE AS A TEMPORARY SETTLING BASIN.
12. WHERE SEEDING FOR TEMPORARY EROSION CONTROL IS
REQUIRED, FAST GERMINATING GROSSES SHALL BE APPLIED AT
AN APPROPRIATE RATE (E.G. ANNUAL OR PERENNIAL RYE APPLIED
