GENERAL ESC NOTES
1.THE TEMPORARY EROSION AND SEDIMENT CONTROL (TESC) PLAN OUTLINED
HEREIN IS CONCEPTUAL. THE CONTRACTOR IS REQUIRED TO SUBMIT A FINAL
TEMPORARY WATER POLLUTION AND EROSION CONTROL PLAN IN ACCORDANCE
WITH SPECIAL PROVISIONS SECTION 1-07.15.
2.THE IMPLEMENTATION OF THESE ESC PLANS AND THE CONSTRUCTION,
MAINTENANCE, REPLACEMENT, AND UPGRADING OF THESE ESC FACILITIES IS
THE RESPONSIBILITY OF THE APPLICANT/ESC SUPERVISOR UNTIL ALL
CONSTRUCTION IS APPROVED.
3.THE ESC FACILITIES SHOWN ON THIS PLAN MUST BE CONSTRUCTED PRIOR TO
OR IN CONJUNCTION WITH ALL CLEARING AND GRADING SO AS TO ENSURE
THAT THE TRANSPORT OF SEDIMENT TO SURFACE WATERS, DRAINAGE
SYSTEMS, AND ADJACENT PROPERTIES IS MINIMIZED.
4.THE ESC FACILITIES SHOWN ON THESE PLANS OR SPECIFIED HEREIN ARE THE
MINIMUM REQUIREMENTS FOR ANTICIPATED SITE CONDITIONS. DURING THE
CONSTRUCTION PERIOD, THESE ESC FACILITIES SHALL BE UPGRADED AS
NEEDED FOR UNEXPECTED STORM EVENTS AND MODIFIED TO ACCOUNT FOR
CHANGING SITE CONDITIONS (E.G., ADDITIONAL SUMP PUMPS, RELOCATION OF
DITCHES AND SILT FENCES, ETC.).
5.THE ESC FACILITIES SHALL BE INSPECTED DAILY BY THE APPLICANT/ESC
SUPERVISOR AND MAINTAINED TO ENSURE CONTINUED PROPER FUNCTIONING.
WRITTEN RECORDS SHALL BE KEPT OF WEEKLY REVIEWS OF THE ESC
FACILITIES DURING THE WET SEASON (OCT. 1 TO APRIL 30) AND OF MONTHLY
REVIEWS DURING THE DRY SEASON (MAY 1 TO SEPT. 30).
6.ANY AREAS OF EXPOSED SOILS, INCLUDING ROADWAY EMBANKMENTS, THAT
WILL NOT BE DISTURBED FOR TWO DAYS DURING THE WET SEASON OR SEVEN
DAYS DURING THE DRY SEASON SHALL BE IMMEDIATELY STABILIZED WITH THE
APPROVED ESC METHODS (E.G., SEEDING, MULCHING, PLASTIC COVERING,
ETC.).
7.ANY AREA NEEDING ESC MEASURES NOT REQUIRING IMMEDIATE ATTENTION
SHALL BE ADDRESSED WITHIN FIFTEEN (15) DAYS.
8.THE ESC FACILITIES ON INACTIVE SITES SHALL BE INSPECTED AND MAINTAINED
A MINIMUM OF ONCE A MONTH OR WITHIN FORTY-EIGHT (48) HOURS FOLLOWING
A STORM EVENT.
9.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.
10.WHERE STRAW MULCH FOR TEMPORARY EROSION CONTROL IS REQUIRED, IT
SHALL BE APPLIED AT A MINIMUM THICKNESS OF 2 TO 3 INCHES.
11.NO STOCKPILING/STAGING WILL BE CONDUCTED WITHIN THE RIGHT OF WAY OR
CITY OWNED SITE. CONTRACTOR IS RESPONSIBLE FOR OBTAINING ITS OWN
STOCKPILE/STAGING AREAS.
12.PUBLIC STREETS SHALL BE CLEANED ONCE PER DAY OR AS DIRECTED BY THE
CITY. FLUSHING OF STREETS WITH WATER WILL NOT BE ALLOWED.
13.IN ACCORDANCE WITH THE DEPARTMENT OF ECOLOGY REQUIREMENTS,
WASTEWATER FROM CEMENT CONCRETE MASONRY, OR ASPHALT CONCRETE
CUTTING, OR POURING OPERATIONS SHALL NOT BE DISCHARGED INTO STORM
DRAINAGE SYSTEMS OR SURFACE WATERS. IMPERVIOUS SURFACES
CONTAMINATED WITH SEDIMENT FROM GRIT AND CUTTING, PLANING OR
PULVERIZING OPERATIONS SHALL BE VACUUM-CLEANED TO PREVENT
CONTAMINANTS FROM ENTERING THE STORM DRAINAGE SYSTEM OR SURFACE
WATERS.
14.CATCH BASIN INSERTS SHALL BE PLACED AT ALL CATCH BASINS ALONG PIPE
ALIGNMENT. SEE CITY OF RENTON STANDARD PLAN 216.30.
15.INSTALL SILT FENCING AROUND ENTIRE STAGING/STOCKPILE AREAS PER COR
STANDARD PLAN 214.
16.TEMPORARY SEDIMENTATION TANK MAY BE REQUIRED IN CONTRACTOR
STAGING AREA IF THE SILT FENCING IS NOT ADEQUATE.
17.KEEP PUBLIC AND PRIVATE ROADWAYS/PARKING LOTS, SIDEWALKS, AND TRAILS
FREE OF DEBRIS AND SEDIMENT.

CONSTRUCTION TO DIVERT STORMWATER AROUND TRENCHING AND PIPE
INSTALLATION ACTIVITIES AND MAINTAIN DRAINAGE OF UPSTREAM
STORMWATER. CONTRACTOR IS RESPONSIBLE FOR DESIGN OF STORM DRAIN
BYPASS PLAN. UNLESS OTHERWISE NOTED, BYPASSES ARE TO BE DESIGNED TO
HANDLE THE VOLUME AND PEAK FLOWS OF THE 2-YEAR STORM EVENT AT A
MINIMUM. SUBMIT AS PART OF WATER CONTROL PLAN. STORM DRAIN BYPASS
PLAN SHALL ALSO ADDRESS THE DOWNSTREAM SYSTEM AND PREVENTION OF
STORMWATER ENTERING THE WORK AREA BY BACKING UP FROM
DOWNSTREAM.
19.ALL DEWATERING WATER AND RUNOFF WITHIN CONSTRUCTION AREAS SHALL
BE TREATED VIA SEDIMENTATION, FILTRATION THROUGH VEGETATION IN
APPROVED AREAS, OR PORTABLE FILTRATION SYSTEMS (UTILIZING TANKS AND
FILTERS), AS NEEDED, PRIOR TO DISCHARGE TO DOWNSTREAM SYSTEM IN
ORDER TO MEET ALL APPLICABLE LOCAL, STATE AND FEDERAL WATER QUALITY
REGULATIONS. CONTRACTOR MAY ALSO DISCHARGE TO THE SANITARY SEWER
SYSTEM AFTER OBTAINING APPLICABLE PERMITS AND MEETING PRETREATMENT
REQUIREMENTS.AS-BUILTAS-BUILT1 BS 07/12 JM
