3. MAINTAIN ALL EXISTING UTILITY SERVICES DURING CONSTRUCTION.
4. VERIFY GRADES PRIOR TO CONSTRUCTION. FLAG CLEARING LIMITS.
5. NO WORK MAY OCCUR WITHIN OHWM OF CREEK UNTIL SPECIFICALLY AUTHORIZED BY ENGINEER AND CITY
INSPECTOR.
6. INSTALL FILTER FABRIC FENCING AND OTHER SEDIMENT CONTROL DEVICES PER DEMOLITION AND T.E.S.0 PLAN,
SHEET C3-101.
7. CLEAR AND GRUB AREA TO BE DISTURBED BY CONSTRUCTION.
8. REMOVE EX. GABION WALL AS NEEDED TO ACCESS CULVERTS. FILL REMAINING PORTIONS OF BASKETS AND
QUARRY SPALLS WITH FLOWABLE FILL. PROVIDE TEMPORARY STABILIZATION FOR ROADWAY AND EXISTING

Erosion Control Notes
1. THESE NOTES SHALL APPEAR FOR ALL PROJECTS - SITE IMPROVEMENTS, SURFACE WATER UTILITY, WASTEWATER
UTILITY, WATER UTILITY, AND TRANSPORTATION PLANS:
2. BEFORE ANY CONSTRUCTION OR DEVELOPMENT ACTIVITY OCCURS, A PRE -CONSTRUCTION MEETING MUST BE HELD
WITH THE CITY OF RENTON, PUBLIC WORKS DESIGN ENGINEER.
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 LIMITS 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 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.
5. ALL REQUIRED SEDIMENTATION/EROSION CONTROL FACILITIES MUST BE CONSTRUCTED AND IN OPERATION PRIOR TO
LAND CLEARING AND/OR CONSTRUCTION TO PREVENT TRANSPORTATION OF SEDIMENT TO SURFACE WATER,
DRAINAGE SYSTEMS AND ADJACENT PROPERTIES. ALL EROSION 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 PASSED. THE IMPLEMENTATION, MAINTENANCE, REPLACEMENT AND ADDITIONS TO
EROSION/SEDIMENTATION CONTROL SYSTEMS SHALL BE THE RESPONSIBILITY OF THE PERMITEE.
6. THE EROSION AND SEDIMENTATION CONTROL SYSTEMS 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 PERMITEE SHALL ANTICIPATE THAT MORE EROSION AND SEDIMENTATION
CONTROL FACILITIES 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 PERMITEE TO
ADDRESS ANY NEW CONDITIONS THAT MAY BE CREATED BY THE ACTIVITIES AND TO PROVIDE ADDITIONAL FACILITIES,
OVER AND ABOVE MINIMUM REQUIREMENTS, AS MAY BE NEEDED, TO PROTECT ADJACENT PROPERTIES AND WATER
QUALITY OF THE RECEIVING DRAINAGE SYSTEM.
7. APPROVAL OF THIS PLAN IS FOR EROSION/SEDIMENTATION CONTROL ONLY. IT DOES NOT CONSTITUTE AN APPROVAL
OF STORM DRAINAGE DESIGN, SIZE NOR LOCATION OF PIPES, RESTRICTORS, 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 THROUGH MARCH 30TH) OR SEVEN DAYS DURING DRAY SEASON (APRIL 1ST
THROUGH SEPTEMBER 30TH) SHALL BE IMMEDIATELY STABILIZED WITH APPROVED ESC COVER METHODS (E.G.,
SEEDING, MULCHING, PLASTIC COVERING, ETC.).
9. WET SEASON SEASONAL EROSION AND SEDIMENT CONTROL REQUIREMENTS APPLY TO ALL CONSTRUCTION SITES
CLEARING BETWEEN 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 ESC MEASURES, NOT REQUIRING IMMEDIATE ATTENTION, SHALL BE ADDRESSED WITHIN SEVEN (7)
DAYS.
12. THE ESC FACILITIES ON INACTIVE SITES SHALL BE INSPECTED AND MAINTAINED A MINIMUM OF ONCE A MONTH OR
WITHIN 12 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 CLEARED PRIOR PAVING. THE CLEANING OPERATION SHALL NOT
FLUSH SEDIMENT -LADEN WATER INTO THE DOWNSTREAM SYSTEM.
14. DURING THE TIME PERIOD OF OCTOBER 1ST THROUGH MARCH 30TH, ALL PROJECT DISTRIBUTED SOIL AREAS
GREATER, THAT ARE TO BE LEFT UN -WORKED FOR MORE THAN 12 HOURS, SHALL BE COVERED BY MULCH, SODDING
OR PLASTIC COVERING.
CONSTRUCTION RECORD DRAWING
This construction record drawing is a copy of a cad file prepared by
COUGHLIN PORTER LUNDEEN and has been edited to reflect field
verified invert and rim elevations of the storm, sanitary sewer and water
main systems. Field verified invert and rim elevations were obtained by
KLB IN AUGUST 2019
The on -site private storm drainage facilities and public/private water and
sewer systems were installed in accordance with the approved plans and
the documented field revisions and function as intended.
