8Q:\2018\2180100\10_CIV\CAD\_Fill and Grade\2180100-SH-TESC.dwg1.BEFORE ANY CONSTRUCTION OR DEVELOPMENT ACTIVITY OCCURS, A
PRE-CONSTRUCTION MEETING SHALL BE HELD AMONG THE CITY OF
RENTON, 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 THE PRE-CONSTRUCTION MEETING 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
FLAGGED BY SURVEY TAPE OR FENCING AND PROTECTED IN THE FIELD
IN ACCORDANCE WITH APPENDIX D OF THE CITY OF RENTON
SURFACE WATER DESIGN MANUAL (RSWDM) PRIOR TO 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.
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 DESIGNATED CONCRETE WASHOUT AREAS ONLY. DO NOT WASH
OUT CONCRETE TRUCKS ONTO THE GROUND, OR TO STORM DRAINS OR
OPEN DITCHES. ON-SITE DUMPING OF EXCESS CONCRETE SHALL ONLY
OCCUR IN DESIGNATED CONCRETE WASHOUT AREAS.
7.ALL REQUIRED ESC BMPS SHALL 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 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 POTENTIAL FOR ON-SITE EROSION DOES NOT
EXIST. THE IMPLEMENTATION, MAINTENANCE, REPLACEMENT,
ENHANCEMENT, AND REMOVAL OF ESC BMPS SHALL BE THE
RESPONSIBILITY OF THE APPLICANT.
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.
11.ANY DEWATERING SYSTEM NECESSARY FOR THE CONSTRUCTION OF
STORMWATER FACILITIES SHALL BE SUBMITTED TO THE CITY FOR
REVIEW AND APPROVAL.
12.ANY AREAS OF EXPOSED SOILS, INCLUDING ROADWAY
EMBANKMENTS, THAT WILL NOT BE DISTURBED FOR TWO DAYS DURING
THE WET SEASON (OCTOBER 1ST THROUGH APRIL 30TH) OR SEVEN
DAYS DURING THE DRY SEASON (MAY 1ST THROUGH SEPTEMBER 30TH)
SHALL BE IMMEDIATELY STABILIZED WITH THE APPROVED ESC
COVER METHODS (E.G., SEEDING, MULCHING, PLASTIC COVERING, ETC.)
IN CONFORMANCE WITH APPENDIX D OF THE RSWDM.
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 THE CITY.
16.BEFORE COMMENCEMENT OF ANY CONSTRUCTION ACTIVITY, CATCH
BASIN INSERTS PER THE CITY STANDARD PLANS SHALL BE PROVIDED
FOR ALL STORM DRAIN INLETS DOWNSLOPE AND WITHIN 500 FEET OF A
DISTURBED OR CONSTRUCTION AREA, UNLESS THE RUNOFF THAT
ENTERS THE INLET WILL BE CONVEYED TO A SEDIMENT POND OR TRAP.
ALL CATCH BASIN INSERTS SHALL BE PERIODICALLY INSPECTED AND
REPLACED AS NECESSARY TO ENSURE FULLY FUNCTIONING
CONDITION.
17.AT NO TIME SHALL SEDIMENT ACCUMULATION EXCEED 2/3 OF THE
CAPACITY OF THE CATCH BASIN SUMP. 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.
18.ANY PERMANENT STORMWATER FACILITY USED AS A TEMPORARY
SETTLING BASIN SHALL BE MODIFIED WITH THE NECESSARY ESC BMPS
AND SHALL PROVIDE ADEQUATE STORAGE CAPACITY. IF THE
PERMANENT FACILITY IS TO FUNCTION ULTIMATELY AS AN INFILTRATION
SYSTEM, THE TEMPORARY FACILITY SHALL BE ROUGH GRADED SO THAT
THE BOTTOM AND SIDES ARE AT LEAST THREE FEET ABOVE THE FINAL
GRADE OF THE PERMANENT FACILITY.
19.AREAS DESIGNATED ON THE PLAN(S) CONTAINING EXISTING
STORMWATER FACILITIES OR ON-SITE BMPS (AMENDED SOILS,
BIORETENTION, PERMEABLE PAVEMENT, ETC.) SHALL BE CLEARLY
FENCED AND PROTECTED USING ESC BMPS TO AVOID SEDIMENTATION
AND COMPACTION DURING CONSTRUCTION.
20.PRIOR TO THE BEGINNING OF THE WET SEASON (OCTOBER 1ST), ALL
DISTURBED AREAS SHALL BE INSPECTED TO IDENTIFY WHICH ONES
SHALL BE SODDED OR SEEDED IN PREPARATION FOR THE WINTER
RAINS. DISTURBED AREAS SHALL BE SODDED OR SEEDED WITHIN ONE
WEEK OF THE BEGINNING OF THE WET SEASON. AN EXHIBIT OF
THOSE AREAS TO BE SODDED OR SEEDED AND THOSE AREAS TO
REMAIN UNCOVERED SHALL BE SUBMITTED TO THE CITY FOR REVIEW.
21.PRIOR TO FINAL CONSTRUCTION ACCEPTANCE, THE PROJECT SITE
SHALL BE STABILIZED TO PREVENT SEDIMENT-LADEN WATER FROM
LEAVING THE PROJECT SITE, ALL ESC BMPS SHALL BE REMOVED, AND
STORMWATER CONVEYANCE SYSTEMS, FACILITIES, AND ON-SITE BMPS
SHALL BE RESTORED TO THEIR FULLY 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 SMALL
AREAS TO BE LANDSCAPED BEFORE OCTOBER 1ST.
22.ROCKERIES ARE CONSIDERED TO BE A METHOD OF BANK
STABILIZATION AND EROSION CONTROL. ROCKERIES SHALL NOT BE
CONSTRUCTED TO SERVE AS RETAINING WALLS. ALL ROCKERIES IN
CITY ROAD RIGHT-OF-WAY SHALL BE CONSTRUCTED IN ACCORDANCE
WITH CITY STANDARDS. ROCKERIES OUTSIDE OF ROAD RIGHT-OF-WAY
SHALL BE CONSTRUCTED IN ACCORDANCE WITH THE INTERNATIONAL
BUILDING CODE.
