GENERAL TESC NOTES:

1. THE EROSION & SEDIMENT CONTROL (ESC) MEASURES SHOWN ON THISPLANS ARE THE MINIMUM REQUIREMENTS FOR ANTICIPATED SITECONDITIONS. DURING THE CONSTRUCTION PERIOD, THESE ESCMEASURES MUST BE UPGRADED AS NEEDED FOR UNEXPECTED STORMEVENTS AND MODIFIED TO ACCOUNT FOR CHANGING SITE CONDITIONS(E.G. ADDITIONAL COVER MEASURES, PUMPING AND CONTAINMENT,RELOCATION OF DITCHES AND SILT FENCES, PERIMETER PROTECTION ETC.)

2. THESE FACILITIES MUST BE SATISFACTORILY MAINTAINED UNTIL THECONSTRUCTION AND LANDSCAPING IS COMPLETED AND THE POTENTIALFOR ONSITE EROSION HAS PASSED. THE ESC PLANS ARE TO BECONSIDERED A DYNAMIC MINIMUM GUIDELINE AND AS SUCH WILL MOSTLIKELY HAVE TO BE CONTINUALLY EVALUATED AND/OR MODIFIEDDEPENDING ON SITE CONDITIONS.

3. THE IMPLEMENTATION OF THESE ESC PLANS AND THE CONSTRUCTION,MAINTENANCE, REPLACEMENT, AND UPGRADING OF THESE ESCFACILITIES IS THE RESPONSIBILITY OF THE DEVELOPER AND ESCSUPERVISOR UNTIL ALL CONSTRUCTION IS APPROVED.

4. STABILIZED CONSTRUCTION ENTRANCES MUST BE INSTALLED AT THEBEGINNING OF CONSTRUCTION AND MAINTAINED FOR THE DURATION OFTHE PROJECT. ADDITIONAL MEASURES, SUCH AS CONSTRUCTED WHEELWASH SYSTEMS OR WASH PADS, MAY BE REQUIRED TO ENSURE THAT ALLPAVED AREAS ARE KEPT CLEAN AND TRACK OUT TO ROAD RIGHT OF WAYDOES NOT OCCUR FOR THE DURATION OF THE PROJECT.

5. THE ESC FACILITIES SHOWN ON THIS PLAN MUST BE CONSTRUCTED PRIORTO OR IN CONJUNCTION WITH ALL CLEARING AND GRADING SO AS TOENSURE THAT THE TRANSPORT OF SEDIMENT TO SURFACE WATERS,DRAINAGE SYSTEMS, AND ADJACENT PROPERTIES IS MINIMIZED.

6. THE ESC FACILITIES MUST BE INSPECTED DAILY BY THE DEVELOPER/ESCSUPERVISOR AND MAINTAINED TO ENSURE CONTINUED PROPERFUNCTIONING. WRITTEN RECORDS MUST BE KEPT OF WEEKLY REVIEWSOF THE ESC FACILITIES.

7. SOILS MUST NOT REMAIN EXPOSED AND UNWORKED FOR MORE THAN 7DAYS FROM MAY 1 THROUGH SEPTEMBER 30 AND NOT MORE THAN 48HOURS FROM OCTOBER 1 AND APRIL 30. EXPOSED AND UNWORKEDSOILS MUST BE COVERED BY MULCH, SODDING, PLASTIC COVERING,JUTE-MATTING, OR AS OTHERWISE APPROVED OR REQUIRED BY THEPUBLIC WORKS CONSTRUCTION INSPECTOR.

8. THE ESC FACILITIES ON INACTIVE SITES MUST BE INSPECTED ANDMAINTAINED A MINIMUM OF ONCE A MONTH DURING THE DRY SEASON,BI-MONTHLY DURING THE WET SEASON, OR WITHIN 24 HOURSFOLLOWING A STORM EVENT.

9. AT NO TIME MAY MORE THAN 6-INCHES OF SEDIMENT BE ALLOWED TOACCUMULATE WITHIN A CATCH BASIN. ALL CATCH BASINS ANDCONVEYANCE LINES MUST BE CLEANED PRIOR TO PAVING AND FINALAPPROVAL. THE CLEANING OPERATION MAY NOT FLUSHSEDIMENT-LADEN WATER INTO THE DOWNSTREAM SYSTEM.

10.DUST GENERATED DURING CONSTRUCTION ACTIVITIES MUST BECONTROLLED BY WETTING DUST SOURCES SUCH AS AREAS OF EXPOSEDSOILS, WASHING TRUCK WHEELS BEFORE THEY LEAVE THE SITE, ANDINSTALLING AND MAINTAINING ROCK CONSTRUCTION ENTRANCES.CONTRACTOR MUST MECHANICALLY SWEEP STREETS DAILY WITHVACUUM SWEEPER UNLESS OTHERWISE APPROVED.

11.ANY EXCAVATED MATERIAL REMOVED FROM THE CONSTRUCTION SITEAND DEPOSITED ON PROPERTY WITHIN THE CITY LIMITS MUST BE DONE INCOMPLIANCE WITH A VALID CLEARING & GRADING PERMIT. LOCATIONSFOR THE MOBILIZATION AREA AND STOCKPILED MATERIAL MUST BEAPPROVED BY THE CLEARING AND GRADING INSPECTOR AT LEAST 24HOURS IN ADVANCE OF ANY STOCKPILING.

12.WHERE STRAW MULCH FOR TEMPORARY EROSION CONTROL ISREQUIRED, IT SHALL BE APPLIED AT A MINIMUM THICKNESS OF 2-INCHES.

13.PRIOR TO SEPTEMBER 15, ALL DISTURBED AREAS SHALL BE REVIEWED TOIDENTIFY WHICH ONES CAN BE SEEDED IN PREPARATION FOR THE WINTERRAINS. DISTURBED AREAS SHALL BE SEEDED PRIOR TO OCTOBER 1.

14.REMOVE ALL ESC MEASURES ONCE ALL WORK IS COMPLETED AND SITE ISPERMANENTLY STABILIZED.

THE ESC FACILITIES SHOWN ON THIS PLAN ARE THE MINIMUMREQUIREMENTS FOR ANTICIPATED SITE CONDITIONS. DURING THECONSTRUCTION PERIOD, THESE ESC FACILITIES SHALL BE UPGRADED ASNEEDED FOR UNEXPECTED STORM EVENTS AND TO ENSURE THATSEDIMENT AND SEDIMENT-LADEN WATER DO NOT LEAVE THE SITE. ANYSUCH FACILITIES INSTALLED MUST BE MAINTAINED IN PROPER OPERATINGCONDITION UNTIL ALL DISTURBED AREAS HAVE BEEN REVEGETATED OROTHERWISE DEVELOPED AND THE POTENTIAL FOR EROSION ELIMINATED.

THE CONTRACTOR SHALL UNCOVERALL INDICATED PIPES WHERE CROSSING INTERFERENCES, ORCONNECTIONS OCCUR PRIOR TO TRENCHING OR EXCAVATIONFOR ANY PIPE OR STRUCTURES, TO DETERMINE ACTUALLOCATIONS, SIZE AND MATERIAL. THE CONTRACTOR SHALLMAKE THE APPROPRIATE PROVISION FOR PROTECTION OFSAID FACILITIES. THE CONTRACTOR SHALL NOTIFY ONE-CALLAT 8-1-1 (WASHINGTON811.COM) AND ARRANGE FOR FIELDLOCATION OF EXISTING FACILITIES PRIOR TO CONSTRUCTION.

GENERAL UTILITY NOTES:

1. TAKE SPECIAL PRECAUTIONS WITH RESPECT TO POWER, GAS,WATER AND TELECOM/DATA UTILITIES.

2. PROVIDE 18-INCH MINIMUM VERTICAL SEPARATIONBETWEEN ALL UTILITIES UNLESS OTHERWISE NOTED.

3. ALL CROSSINGS WITH SEPARATION OF LESS THAN 12-INCHESSHALL BE CONSTRUCTED WITH A 6-INCH RIGID FOAM PAD,ETHAFOAM PAD, OR EQUIVALENT.

4. COORDINATE WITH WATER DISTRICT FOR WATER SERVICESHUTOFF PRIOR TO ANY DEMOLITION ACTIVITY.

5. ALL PROPOSED SIDE SEWERS TO THE BUILDING SHALL HAVEA MINIMUM SLOPE OF 2 PERCENT.

6. UNLESS OTHERWISE NOTED, ALL STORM DRAIN PIPE SHALLBE ADS N-12 OR ASTM 3034 PVC PIPE, OR APPROVED EQUAL.ALL ROOF DRAIN PIPES SHALL BE 4” OR LARGER.

7. ALL UTILITY TRENCHES SHALL BE BACKFILLED ANDCOMPACTED TO 95 PERCENT DENSITY.

THE CONTRACTOR SHALL COORDINATE SIDEWALK CLOSURES,STREET CLOSURES AND RIGHT-OF-WAY USE PERMITS WITH THECITY OF SEATTLE DEPARTMENT OF TRANSPORTATION (SDOT)

GENERAL DRAINAGE NOTES:
