MINIMUM STANDARDS (PHASE 11) FROM VESCH
PROTECT ALL STORM SEWER INLETS THAT ARE MADE OPERABLE DURING CONSTRUCTION SO THAT
SEDIMENT -LADEN WATER CANNOT ENTER THE CONVEYANCE SYSTEM WITHOUT FIRST BEING FILTERED OR
OTHERWISE TREATED TO REMOVE SEDIMENT.
BEFORE STORMWATER CONVEYANCE CHANNELS ARE MADE OPERATIONAL, PROVIDE ADEQUATE OUTLET
PROTECTION AND ANY REQUIRED TEMPORARY OR PERMANENT CHANNEL LINING IN BOTH THE CONVEYANCE
CHANNEL AND THE RECEIVING CHANNEL.
WHEN WORK IN A LIVE WATERCOURSE IS PERFORMED, TAKE PRECAUTIONS TO MINIMIZE ENCROACHMENT,
CONTROL SEDIMENT TRANSPORT AND STABILIZE THE WORK AREA TO THE GREATEST EXTENT POSSIBLE DURING
CONSTRUCTION. PROVIDE NONERODIBLE MATERIAL FOR THE CONSTRUCTION OF CAUSEWAYS AND
COFFERDAMS. EARTHEN FILL MAY BE USED FOR THESE STRUCTURES IF ARMORED BY NONIERODIBLE COVER
MATERIALS.
WHEN A LIVE WATERCOURSE MUST BE CROSSED BY CONSTRUCTION VEHICLES MORE THAN TWICE IN ANY
SIX -MONTH PERIOD, PROVIDE A TEMPORARY STREAM CROSSING CONSTRUCTED OF NONEIRODIBLE MATERIAL.
MEET ALL APPLICABLE FEDERAL, STATE AND LOCAL REGULATIONS PERTAINING TO WORKING IN OR CROSSING
LIVE WATERCOURSES.
STABILIZE THE BED AND BANKS OF A WATERCOURSE IMMEDIATELY FOLLOWING AFTER WORK IN THE
WATERCOURSE IS COMPLETED.
UNDERGROUND UTILITY LINES SHALL BE INSTALLED IN ACCORDANCE WITH THESE STANDARDS IN ADDITION TO
OTHER APPLICABLE CRITERIA:
A. OPEN NO MORE THAN 500 LINEAR FEET OF TRENCH AT ONE TIME.
B. PLACE EXCAVATED MATERIAL ON THE UPHILL SIDE OF TRENCHES.
C. FILTER EFFLUENT FROM DEWATERING OPERATIONS OR PASS THROUGH AN APPROVED SEDIMENT
TRAPPING DEVICE, OR BOTH, AND DISCHARGE IN A MANNER THAT DOES NOT ADVERSELY AFFECT FLOWING
STREAMS OR OFFSITE PROPERTY.
D. MATERIAL USED FOR BACKFILLING TRENCHES SHALL BE PROPERLY COMPACTED IN ORDER TO MINIMIZE
EROSION AND PROMOTE STABILIZATION.
E. ACCOMPLISH RESTABILIZATION IN ACCORDANCE WITH THESE REGULATIONS.
F. COMPLY WITH ALL APPLICABLE SAFETY REGULATIONS.
WHERE CONSTRUCTION VEHICLE ACCESS ROUTES INTERSECT PAVED PUBLIC ROADS, MAKE PROVISIONS TO
MINIMIZE THE TRANSPORT OF SEDIMENT BY VEHICULAR TRACKING ONTO THE PAVED SURFACE. WHERE
SEDIMENT IS TRANSPORTED ONTO A PUBLIC ROAD SURFACE, CLEAN THE ROAD THOROUGHLY AT THE END OF
EACH DAY. REMOVE SEDIMENT FROM THE ROADS BY SHOVELING OR SWEEPING AND TRANSPORT TO A
SEDIMENT CONTROL DISPOSAL AREA. STREET WASHING SHALL BE ALLOWED ONLY AFTER SEDIMENT IS
REMOVED IN THIS MANNER.
REMOVE ALL TEMPORARY EROSION AND SEDIMENT CONTROL MEASURES WITHIN 30 DAYS AFTER FINAL SITE
STABILIZATION BUT ONLY AFTER THE TEMPORARY MEASURES ARE NO LONGER NEEDED, AND ONLY AFTER
AUTHORIZED BY THE EROSION CONTROL INSPECTOR. PERMANENTLY STABILIZE TRAPPED SEDIMENT AND THE
DISTURBED SOIL AREAS RESULTING FROM THE DISPOSITION OF TEMPORARY MEASURES TO PREVENT FURTHER
EROSION AND SEDIMENTATION.
PROPERTIES AND WATERWAYS DOWNSTREAM FROM DEVELOPMENT SITES SHALL BE PROTECTED FROM
SEDIMENT DEPOSITION, EROSION AND DAMAGE DUE TO INCREASES IN VOLUME, VELOCITY( AND PEAK FLOW f'.-ATE
OF STORMWATER RUNOFF FOR THE STATED FREQUENCY STORM OF 24 -HOUR DURATION IIN ACCORDANCE WITH
THE FOLLOWING STANDARDS AND CRITERIA:
A. CONCENTRATED STORMWATER RUNOFF LEAVING A DEVELOPMENT SITE SHALL BE DISCHARGED DIRECTLY
INTO AN ADEQUATE NATURAL OR MAN -MADE RECEIVING CHANNEL, PIPE OR STORM SEWER SYSTEM. FOR
THOSE SITES WHERE RUNOFF IS DISCHARGED INTO A PIPE OR PIPE SYSTEM, DOWNSTREAM STABILITY
ANALYSES AT THE OUTFALL OF THE PIPE OR PIPE SYSTEM SHALL BE PERFORMED.
B. ADEQUACY OF ALL CHANNELS AND PIPES SHALL BE VERIFIED IN THE FOLLOWING MANNER:
(1) THE APPLICANT SHALL DEMONSTRATE THAT THE TOTAL DRAINAGE AREA TO 'THE POINT OF ANALYSIS
WITHIN THE CHANNEL IS ONE HUNDRED TIMES GREATER THAN THE CONTRIBUTING DRAINAGE AREA
OF THE PROJECT IN QUESTION.
(2) NATURAL CHANNELS SHALL BE ANALYZED BY THE USE OF A TEN -YEAR FREQUENCY STORM TO
VERIFY THAT STORMWATER WILL NOT OVERTOP CHANNEL BANKS AND TWO -YEAR VELOCITY TO
VERIFY NO EROSION OF CHANNEL BED OR BANKS.
(3) ALL PREVIOUSLY CONSTRUCTED MAN -MADE CHANNELS SHALL BE ANALYZED BY THE USE OF A
TEN -YEAR FREQUENCY STORM TO VERIFY THAT STORMWATER WILL NOT OVERTOP ITS BANKS AND
BY THE USE OF A TWO -YEAR STORM TO DEMONSTRATE THAT STORMWATER (WILL NOT CAUSE
EROSION OF CHANNEL BED OR BANKS.
(4) PIPES AND STORM SEWER SYSTEMS SHALL BE ANALYZED BY THE USE OF A TEN -YEAR FREQUENCY
STORM TO VERIFY THAT STORMWATER WILL BE CONTAINED WITHIN THE PIPE OR SYSTEM.
C. IF EXISTING NATURAL RECEIVING CHANNELS OR PREVIOUSLY CONSTRUCTED MAN - IMADE CHANNELS OR
PIPES ARE NOT ADEQUATE, THE APPLICANT SHALL:
(1) IMPROVE THE CHANNELS TO A CONDITION WHERE A TEN-YEAR FREQUENCY:STORM WILL NOT
OVERTOP THE BANKS AND A TWO -YEAR FREQUENCY STORM WILL NOT CAUSE EROSION TO THE
CHANNEL BED OR BANKS; OR
(2) IMPROVE THE PIPE OR PIPE SYSTEM TO A CONDITION WHERE THE TEN -YEAR; FREQUENCY STORM IS
CONTAINED WITHIN THE APPURTENANCES, OR
(3) DEVELOP A SITE DESIGN THAT WILL NOT CAUSE THE PRE - DEVELOPMENT PEAK RUNOFF RATE FROM
A TWO -YEAR STORM TO INCREASE WHEN RUNOFF OUTFALLS INTO A NATURAL CHANNEL OR WILL
NOT CAUSE THE PRE - DEVELOPMENT PEAK RUNOFF RATE FROM A TEN -YEAR STORM TO INCREASE
WHEN RUNOFF OUTFALLS INTO A MAN -MADE CHANNEL.
(4) PROVIDE A COMBINATION OF CHANNEL IMPROVEMENT, STORMWATER DETENTION /RETENTION OR
OTHER MEASURES WHICH IS SATISFACTORY TO THE PLAN APPROVING AUTHIORITY TO PREVENT
DOWNSTREAM EROSION.
D. THE APPLICANT SHALL PROVIDE EVIDENCE OF PERMISSION TO MAKE THE IMPROVEWENTS.
E. ALL HYDROLOGIC ANALYSES SHALL BE BASED ON THE EXISTING WATERSHED CHARACTERISTICS AND THE
ULTIMATE DEVELOPMENT CONDITION OF THE SUBJECT PROJECT.
F. IF THE APPLICANT CHOOSES AN OPTION THAT INCLUDES STORMWATER DETENTION/ RETENTION, HE SHALL
OBTAIN APPROVAL FROM THE LOCALITY OF A PLAN FOR MAINTENANCE OF THE DETENTION FACILITIES. THE
PLAN SHALL SET FORTH THE MAINTENANCE REQUIREMENTS OF THE FACILITY AND THE PERSON
RESPONSIBLE FOR PERFORMING THE MAINTENANCE.
G. OUTFALL FROM A DETENTION FACILITY SHALL BE DISCHARGED TO A RECEIVING CHANNEL AND ENERGY
DISSIPATERS SHALL BE PLACED AT THE OUTFALL OF ALL DETENTION FACILITIES AS NECESSARY TO
PROVIDE A STABILIZED TRANSITION FROM THE FACILITY TO THE RECEIVING CHANNEL.
H. ALL ON-SITE CHANNELS MUST BE VERIFIED TO BE ADEQUATE.
1. INCREASED VOLUMES OF SHEET FLOWS THAT MAY CAUSE EROSION OR SEDIMENTATION ON ADJACENT
PROPERTY SHALL BE DIVERTED TO A STABLE OUTLET, ADEQUATE CHANNEL OR DETENTION FACILITY.
J. IN APPLYING THESE STORMWATER RUNOFF CRITERIA, INDIVIDUAL LOTS OR PARCELS IN A RESIDENTIAL,
COMMERCIAL OR INDUSTRIAL DEVELOPMENT SHALL NOT BE CONSIDERED TO BE SEPARATE DEVELOPMENT
PROJECTS. INSTEAD, THE DEVELOPMENT, AS A WHOLE, SHALL BE CONSIDERED TO DE A SINGLE
DEVELOPMENT PROJECT, HYDRAULIC PARAMETERS THAT REFLECT THE ULTIMATE DEVELOPMENT
CONDITION SHALL BE USED IN ALL ENGINEERING CALCULATIONS.
K. ALL MEASURES USED TO PROTECT THE PROPERTIES AND WATERWAYS SHALL BE EIMPLOYED IN A MANNER
WHICH MINIMIZES IMPACTS ON THE PHYSICAL, CHEMICAL AND BIOLOGICAL INTEGRITY OF RIVERS, STREAMS
AND OTHER WATERS OF THE STATE.
