N
T' 2. BEFORE ANY CONSTRUCTION OR DEVELOPMENT ACTIVITY OCCURS, A
0 PRE -CONSTRUCTION MEETING MUST BE HELD WITH THE CITY OF RENTON,
CD PUBLIC WORKS DESIGN ENGINEER.

r 3. THE BOUNDARIES OF THE CLEARING LIMITS AND AREAS OF VEGETATION PRESERVATION
AS PRESCRIBED ON THE PLAN(S) SHALL BE CLEARLY FLAGGED BY SURVEY TAPE OR FENCING
IN THE FIELD PRIOR TO CONSTRUCTION IN ACCORDANCE WITH APPENDIX "D" OF THE SURFACE
WATER DESIGN MANUAL AND OBSERVED DURING CONSTRUCTION. DURING THE CONSTRUCTION
PERIOD, NO DISTURBANCE BEYOND THE CLEARING LIMTS SHALL BE PERMITTED. THE CLEARING
LIMITS SHALL BE MAINTAINED BY THE APPLICANT/ESC SUPERVISOR FOR THE DURATION OF CONSTRUCTION.
4. STABILIZED CONSTRUCTION ENTRANCES SHALL BE INSTALLED AT THE BEGINING OF CONSTRUCTION
Q AND MAINTAINED FOR THE DURATION OF THE PROJECT. ADDITIONAL MEASURES, SUCH AS
J 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
F-- FOR THE DURATION OF THE PROJECT.
5. ALL REQUIRED SEDIMENTATION/EROSION CONTROL FACILITIES MUST BE CONSTRUCTED AND IN
0 OPERATION PRIOR TO LAND CLEARING AND/OR CONSTRUCTION TO PREVENT TRANSPORTATION OF
= SEDIMENT TO SURFACE WATER, DRAINAGE SYSTEMS AND ADJACENT PROPERTIES. ALL EROSION
W AND SEDIMENT FACILITIES SHALL BE MAINTAINED IN A SATISFACTORY CONDITION UNTIL SUCH TIME
THAT CLEARING AND/OR CONSTRUCTION IS COMPLETE AND
POTENTIAL FOR ON-SITE EROSION HAS
0 PASSED. THE IMPLEMENTATION, MAINTENANCE, REPLACEMENT AND ADDITIONS TO EROSION/
C� SEDIMENTATION CONTROL SYSTEMS SHALL BE THE RESPONSIBILITY OF THE PERMITTEE.
W 6. THE EROSION AND SEDIMENTATION CONTROL SYSTEMS DEPICTED ON THIS DRAWING ARE
m INTENDED TO BE MINIMUM REQUIREMENTS TO MEET ANTICIPATED SITE CONDITIONS. AS
2 CONSTRUCTION PROGRESSES AND UNEXPECTED OR SEASONAL CONITIONS DICTATE, THE PERMITEE
0 SHALL ANTICIPATE THAT MORE EROSION AND SEDIMENTATION CONTROL FACILITIES WILL BE
a: NECESSARY TO INSURE COMPLETE SILTATION CONTROL ON THE PROPSED SITE. DURING THE
COURSE OF CONSTRUCTION, IT SHALL BE THE OBLIGATION AND RESPONSIBILITY OF THE PERMITEE
W TO ADDRESS ANY NEW CONDITIONS THAT MAY BE CREATED BY THE ACTIVITIES AND TO PROVIDE
W ADDITIONAL FACILITIES, OVER AND ABOVE MINIMUM REQUIREMENTS, AS MAY BE NEEDED, TO
PROTECT ADJACENT PROPERTIES AND WATER QUALITY OF THE RECIEVING DRAINAGE SYSTEM.
Z 7. APPROVAL OF THIS PLAN IS FOR EROSION/SEDIMENTATION CONTROL ONLY. IT DOES NOT
-J CONSTITUTE AN APPROVAL OF STORM DRAINAGE DESIGN, SIZE NOR LOCATION OF PIPES, RESTRICTORS,
Y CHANNELS, OR RETENTION FACILITIES.
8. ANY AREAS OF EXPOSED SOILS, INCLUDING ROADWAY EMBANKMENTS, THAT WILL NOT BE
DISTURBED FOR TWO DAYS DURING THE WET SEASON (OCTOBER 1ST - MARCH 30TH) OR
SEVEN DAYS DURING THE DRY SEASON (APRIL 1ST - SEPTEMBER 30TH) SHALL BE
IMMEDIATELY STABILIZED WITH THE APPROVED ERC COVER METHODS (e.g. SEEDING,
MULCHING, PLASTIC COVERING, ETC.).
9. WET SEASON SEASONAL EROSION AND SEDIMENT CONTROL REQUIREMENTS APPLY TO ALL
CONSTRUCTION SITES CLEARING BEWTEEN OCTOBER 1 AND MARCH 30 INCLUSIVE, UNLESS
OTHERWISE APPROVED BY THE CITY THROUGH AN ADJUSTMENT PROCESS.
10. COVER MEASURES WILL BE APPLIED IN CONFORMANCE WITH APPENDIX "D" OF THE SURFACE
WATER DESIGN MANUAL.
11. ANY AREA NEEDING ERC MEASURES, NOT REQUIRING IMMEDIATE ATTENTION, SHALL BE
ADDRESSED WITHIN SEVEN (7) DAYS.
12. THE ERC FACILITIES ON INACTIVE SITES SHALL BE INSPECTED AND MAINTAINED A MINIMUM OF
ONCE A MONTH OR WITHIN 24 HOURS FOLLOWING A STORM EVENT.
13. 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.
14. DURING THE TIME PERIOD OF OCTOBER 1ST - MARCH 30TH, ALL PROJECT DISTURBED SOIL AREAS,
THAT ARE TO BE LEFT UN -WORKED FOR MORE THAN 12 HOURS, SHALL BE COVERED
BY MULCH, SODDING, OR PLASTIC COVERING.
15. 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
SYSTEM, THE TEMPORARY FACILITY MUST BE ROUGH GRADED SO THAT THE BOTTOM AND SIDES
ARE AT LEAST THREE FEET ABOVE THE FINAL GRADE OF THE PERMANENT FACILITY.
16. PRIOR TO THE BEGINNING OF THE WET SEASON (OCT. 1), ALL DISTURBED AREAS SHALL BE
REVIEWED TO IDENTIFY WHICH ONES 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 OF RENTON FOR REVIEW.
REFER TO THE TREE RETENTION PLAN SHEET FOR THE
PROTECTION MEASURES
EROSION CONTROL NOTES:
(A) THE SOIL MOISTURE HOLDING CAPACITY OF ALL NEW PREVIOUS SURFACE THAT AT
PROJECT COMPLETION WILL NOT BE COVERED BY IMPERVIOUS SURFACE OR INCORPORATED
INTO A DRAINAGE FACILITY MUST BE PROTECTED. THE DUFF LAYER AND NATIVE TOPSOIL
SHALL BE RETAINED IN AN UNDISTURBED STATE TO THE MAXIMUM STENT FEASIBLE.
(B) ANY DUFF LAYER OR TOPSOIL REMOVED DURING GRADING SHALL BE STOCKPILED ONSITE
IN A DESIGNATED, CONTROLLED AREA NOT ADJACENT TO PUBLIC RESOURCES AND CRITICAL
AREAS. THE MATERIAL SHALL BE REAPPLIED TO OTHER PORTIONS OF THE SITE WHERE
FEASIBLE.
(C) THE SOIL IN ANY AREA THAT HAS BEEN COMPACTED OR THAT HAS SOME OR ALL
OF THE DUFF LAYER OR UNDERLYING TOPSOIL REMOVED SHALL BE AMENDED TO MITIGATE
FOR LOSS OF MOISTURE -CAPACITY. THE AMENDMENT SHALL TAKE PLACE BETWEEN MAY 1
AND OCTOBER 1. REPLACED TOPSOIL SHALL BE A MINIMUM 8 INCHES THICK. REPLACED
TOPSOIL SHALL HAVE AN ORGANIC MATTER CONTENT BETWEEN 8 AND 13 PERCENT DRY
WEIGHT AND A pH SUITABLE FOR THE PROPOSED LANDSCAPE PLANTS.
