CONTRACTOR TO INSTALL TEMPORARY CREEK BYPASS SYSTEM. BYPASS
SYSTEM SHOWN ON THIS DRAWING IS SCHEMATIC AND CONTRACTOR SHALL
SUBMIT BYPASS PLAN IN ACCORDANCE WITH THE SPECIFICATIONS FOR
APPROVAL BY THE CITY. LOCATE PIPE AND COFFER DAMS TO ALLOW
FOR CONSTRUCTION OF OTHER IMPROVEMENTS INCLUDING HEADWALL,
BOULDER CASCADE AND CULVERT BAFFLES. UPON COMPLETION OF
PROJECT, ALL MATERIAL USED FOR THE TEMPORARY BYPASS SHALL BE
REMOVED FROM THE SITE AND THE SITE RESTORED TO PRE -PROJECT
CONDITIONS,
O2 24" DIAMETER CREEK BYPASS PIPE SHALL HAVE SMOOTH INTERIOR WALL
AND SHALL BE MITERED AT INLET. PIPE SHALL BE SUPPORTED WITHIN
EXISTING 78" CULVERT USING CONTRACTOR -DESIGNED SYSTEM. BYPASS
PIPE SHALL EXTEND FAR ENOUGH DOWNSTREAM TO ELIMINATE NEED FOR
A DOWNSTREAM COFFER DAM AND SHALL EXTEND FAR ENOUGH THAT
OUTLET ELEVATION IS A MINIMUM OF 2 VERTICAL FEET BELOW WORK
AREA. ELEVATION OF INLET SHALL BE 153 FT.
O3 PROVIDE SAND OR GRAVEL -FILLED COFFER DAM SYSTEM TO ELEVATION
156 FT ON UPSTREAM SIDE OF CULVERT. COFFER DAM SYSTEM TO BE
CONTRACTOR -DESIGNED TO WITHSTAND ANTICIPATED HYDROSTATIC FORCES
AND WITHSTAND OVERTOPPING.
® CONNECT 12" TEMPORARY STORM DRAIN TO EXISTING 12" CMP AND
DIRECT FLOW TO UPSTREAM SIDE OF COFFER DAM.
O INSTALL CATCH BASIN INSERTS (4) AT FIRST CB WEST AND EAST OF
CULVERT. SEE DETAIL 1 ON DWG C2.
CD EXCAVATE SUMP AT LOW POINT WHERE FLOWS EXIST EXISTING CULVERT.
LINE SUMP WITH PLASTIC. DIRECT ANY CONTAMINATED CONSTRUCTION
WATER/SEEPAGE (E.G., AFTER SAND BLASTING OPERATIONS OR CONCRETE
WORK) DISCHARGING FROM CULVERT TO SUMP AND PUMP TO HOLDING
TANK FOR HAUL TO DISPOSAL SITE. UPON REMOVAL OF EXISTING
DAMAGED CULVERT SECTION, RELOCATE SUMP TO CAPTURE CULVERT
SEEPAGE.
1. THE IMPLEMENTATION OF THESE ESC PLANS AND THE CONSTRUCTION, MAINTENANCE,
REPLACEMENT, AND UPGRADING OF THESE ESC FACILITIES IS THE RESPONSIBILITY OF THE
CONTRACTOR UNTIL ALL CONSTRUCTION IS APPROVED.
2. THE BOUNDARIES OF THE CONSTRUCTION LIMITS SHOWN ON THIS PLAN SHALL BE CLEARLY
FLAGGED BY THE CONTRACTOR USING YELLOW CONSTRUCTION TAPE WITH 2"X4" WOODEN STAKES
SPACED AT 20' MAXIMUM PRIOR TO CONSTRUCTION. ELECTRONIC FILES WILL BE PROVIDED TO THE
CONTRACTOR FOR LOCATION OF THE LIMITS. DURING THE CONSTRUCTION PERIOD, NO
DISTURBANCE BEYOND THE CONSTRUCTION LIMITS SHALL BE PERMITTED. THE CONSTRUCTION
LIMITS SHALL BE MAINTAINED BY THE CONTRACTOR FOR THE DURATION OF CONSTRUCTION. LARGE
WOODY DEBRIS MAY BE PLACED OUTSIDE THE CONSTRUCTION LIMITS.
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 THIS PLAN ARE THE MINIMUM REQUIREMENTS FOR ANTICIPATED
SITE CONDITIONS. DURING THE CONSTRUCTION PERIOD, THESE ESC FACILITIES SHALL BE
UPGRADED AS NEEDED FOR CONSTRUCTION SEQUENCING AND UNEXPECTED STORM EVENTS AND
SHALL BE 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 CONTRACTOR AND MAINTAINED TO
ENSURE CONTINUED PROPER FUNCTIONING. WRITTEN RECORDS SHALL BE KEPT OF WEEKLY
REVIEWS OF THE ESC FACILITIES. DAMAGED OR IMPROPERLY FUNCTIONING BMPS SHALL BE
REPLACED AT NO ADDITIONAL COST TO THE CITY.
6. ANY AREAS OF EXPOSED SOILS THAT WILL NOT BE DISTURBED FOR TWO DAYS SHALL BE
IMMEDIATELY STABILIZED WITH THE APPROVED ESC METHODS (E.G., SEEDING, MULCHING, PLASTIC
COVERING, ETC.).
7. AT NO TIME SHALL MORE THAN ONE (1) FOOT OF SEDIMENT BE ALLOWED TO ACCUMULATE WITHIN
A CATCH BASIN. THE CLEANING OPERATION SHALL NOT FLUSH SEDIMENT -LADEN WATER INTO THE
DOWNSTREAM SYSTEM.
8. WHERE STRAW MULCH FOR TEMPORARY EROSION CONTROL IS REQUIRED, IT SHALL BE APPLIED AT
A MINIMUM THICKNESS OF 2 TO 3 INCHES.
07 INSTALL TEMPORARY SILT FENCE ACROSS CREEK BOTTOM AND AT TOP OF
CHANNEL BANKS ALONG CREEK. SEE DETAIL 2 ON DWG C2. AS 9. USE REINFORCED PLASTIC FABRIC TO COVER STOCKPILED ITEMS WHEN NOT IN USE. THE
