EXISTING SURFACE TO RECEIVE FILL SHOULD BE SCARIFIED
PRIOR TO FILLING.  ANY FILLING OPERATION SHOULD NOT
OCCUR DURING WATER SATURATED SOIL CONDITIONS.
WATERCOURSE AND WETLAND IMPACT
AVOIDANCE AND MINIMIZATION
MEASURES:
1.
THE FOLLOWING MEASURES WILL BE TAKEN TO AVOID OR
MINIMIZE IMPACTS TO WATERCOURSES AND WATERBODIES
DURING PROJECT ACTIVITIES.  ALL WORK IN OR NEAR
WATERCOURSES AND WATERBODIES WILL BE IN
ACCORDANCE WITH PROJECT MAPPING AND THE 2002
CONNECTICUT GUIDELINES FOR SOIL EROSION AND
SEDIMENT CONTROL.
2.
INSTALL AND MAINTAIN TEMPORARY EROSION AND
SEDIMENTATION CONTROLS ALONG THE ROW WHERE
CONSTRUCTION ACTIVITIES DISTURB SOILS NEAR
WATERCOURSES. THESE CONTROLS WILL BE INSTALLED AND
MAINTAINED TO MINIMIZE THE POTENTIAL FOR
SEDIMENTATION INTO WATER RESOURCES.  SEDIMENT THAT
ACCUMULATES BEHIND THESE CONTROLS WILL PERIODICALLY
BE REMOVED AND PLACED IN UPLAND AREAS, IN A MANNER
THAT WILL PRECLUDE THE POTENTIAL FOR SUBSEQUENT
DEPOSITION INTO WATERCOURSES, INLAND WETLAND AREAS,
OR WILL OTHERWISE BE DISPOSED OF OFF-SITE.
3.
CONSTRUCTION EQUIPMENT SHALL BE PROHIBITED FROM
FORDING STREAMS.
4.
EXCEPT FOR EQUIPMENT THAT IS NOT READILY MOBILE OR
MUST REMAIN ON-SITE FOR PROLONGED PERIODS TO SAFELY
COMPLETE A CONSTRUCTION TASK, CONSTRUCTION VEHICLES
AND EQUIPMENT WILL NOT BE REFUELED WITHIN 100 FEET OF
A WATERCOURSE OR OPEN WATERS.  FOR REFUELING THAT
MUST BE PERFORMED LESS THAN 25 FEET FROM A
WATERCOURSE, APPROPRIATE SPILL PREVENTION MEASURES
AS DETAILED IN THE CONTRACTOR'S SPILL PREVENTION AND
CONTROL PLAN WILL BE APPLIED.
WETLAND RESTORATION PLAN:
1.
AS NECESSARY, WETLAND AREAS AFFECTED BY
CONSTRUCTION MAY BE STABILIZED TEMPORARILY WITH
ANNUAL RYEGRASS, OR AS DIRECTED BY THE LANDSCAPE
ARCHITECT.  FOR LONG-TERM STABILIZATION IN AREAS
WHERE THE TOPSOIL LAYER (CONTAINING WETLAND SEEDS)
WAS DISTURBED BY CONSTRUCTION, ANNUAL RYE GRASS, A
WETLAND SEED MIX, OR AN EQUIVALENT MIX WILL BE
APPLIED AT THE LABEL-RECOMMENDED SEEDING RATE.   IF
FINE GRADING IS NECESSARY, IT SHOULD BE PERFORMED
DURING THE GROWING SEASON AND IN A MANNER THAT
RETAINS THE EXISTING WETLAND TOPSOIL AND ROOT MASS
TO THE EXTENT PRACTICABLE.  ONCE COMPLETE, DISTURBED
AREAS AFFECTED BY GRADING SHALL BE SEEDED
IMMEDIATELY.
2.
TEMPORARY EROSION AND SEDIMENT CONTROLS WILL BE
LEFT IN PLACE AND MAINTAINED UNTIL FINAL STABILIZATION
IS ACHIEVED.  RESTORATION TYPICALLY WILL BE DEEMED
SUCCESSFUL BASED ON THE ESTABLISHMENT OF PERMANENT
VEGETATIVE COVER.  BASED ON THE RESULTS OF
POST-CONSTRUCTION INSPECTIONS OF AREAS OF
STABILIZATION, THE LANDSCAPE ARCHITECT WILL DETERMINE
THE APPROPRIATE TIMEFRAME FOR THE REMOVAL OF ALL
TEMPORARY EROSION CONTROLS.
ENVIRONMENTAL BMP & PROTECTION:
1.
NO CONSTRUCTION SHALL PROCEED UNTIL PROPER
SEDIMENTATION AND EROSION CONTROL METHODS HAVE
BEEN INSTALLED AS THE SEQUENCE OF CONSTRUCTION
NECESSITATES.
2.
NO EQUIPMENT, MATERIALS OR MACHINERY SHALL BE
STORED, CLEANED OR REPAIRED WITHIN SEVENTY-FIVE (75)
FEET OF ANY WETLAND OR WATERCOURSE.
3.
NO OBJECTIONABLE MATERIALS RESULTING FROM ANY

OR WATERCOURSE.  THIS INCLUDES, BUT IS NOT LIMITED TO,
STUMPS, TREE ROOTS, MATTED ROOTS, WOOD CHIPS AND
OTHER DEBRIS.
4.
FORDING STREAMS WITH EQUIPMENT SHALL BE PROHIBITED
UNLESS SPECIFIED ELSEWHERE.  APPROVAL FROM THE TOWN
OF WATERFORD CONSERVATION COMMISSION WILL BE
REQUIRED FOR ANY HAUL ROAD OR TEMPORARY STRUCTURE
PLACED IN WETLANDS OR WATERCOURSES.
5.
NO SOIL FILL OR OTHER MATERIALS SHALL BE DEPOSITED IN
SURROUNDING WETLANDS OR WATERCOURSES EXCEPT AS
OTHERWISE APPROVED BY THE TOWN OF WATERFORD
CONSERVATION COMMISSION AND DEPICTED HEREON.
6.
WHERE DEWATERING IS NECESSARY, THE PUMP SHALL NOT
DISCHARGE DIRECTLY INTO ANY WETLAND OR WATERCOURSE.
PROPER METHODS AND DEVICES SHALL BE UTILIZED, SUCH
AS PUMPING THE WATER INTO A TEMPORARY SEDIMENTATION
POOL, PROVIDING SURGE PROTECTION AT THE INLET AND THE
OUTLET OF PUMPS, FLOATING THE INTAKE OF THE PUMP, OR
OTHER METHODS TO MINIMIZE AND RETAIN THE SUSPENDED
SOLIDS.  IF THE PUMPING OPERATION IS CAUSING TURBIDITY
PROBLEMS, SAID OPERATION SHALL CEASE UNTIL FEASIBLE
MEANS OF CONTROLLING TURBIDITY ARE DETERMINED AND
IMPLEMENTED.
7.
ALL TEMPORARY FILL, STORAGE OR STOCKPILE AREAS SHALL
BE PROPERLY STABILIZED TO PREVENT EROSION AND
SUITABLY CONTAINED TO PREVENT TURBID RUNOFF FROM
REENTERING A WETLAND OR WATERCOURSE.  ALL AREAS
AFFECTED BY TEMPORARY FILLS MUST BE RESTORED TO
THEIR ORIGINAL CONTOURS, AND RE- VEGETATED WITH
SUITABLE VEGETATION.  THE USE OF TEMPORARY FILL
AND/OR EXCAVATION SHALL BE MINIMIZED TO ONLY THAT
AREA REQUIRED TO PERFORM THE WORK.
8.
DUMPING OF OIL OR OTHER DELETERIOUS MATERIALS ON THE
GROUND IS FORBIDDEN.  THE CONTRACTOR SHALL PROVIDE
A MEANS OF CATCHING, RETAINING AND PROPERLY
DISPOSING OF DRAINED OIL, REMOVED OIL FILTERS, OR
OTHER DELETERIOUS MATERIAL FROM EQUIPMENT USED ON
SITE.  VEHICLE MAINTENANCE EXCEPT DAILY AND PERIODIC
PROCEDURES SHALL BE COMPLETED OFF SITE.  ALL OIL
SPILLS SHALL BE IMMEDIATELY REPORTED TO THE
DEPARTMENT OF ENVIRONMENTAL PROTECTION/HAZARDOUS
MATERIALS OFFICE.  FAILURE TO DO SO MAY RESULT IN THE
IMPOSITION OF FINES UNDER THE APPLICABLE CONNECTICUT
GENERAL STATUTES.
9.
EVERY PRECAUTION SHALL BE USED WHILE WORKING NEAR A
WATERWAY TO PREVENT AND MINIMIZE THE DEGRADATION
OF THE EXISTING WATER QUALITY.  ALL ACTIVITIES SHALL BE
IN CONFORMANCE TO AND CONSISTENT WITH ALL
APPLICABLE WATER QUALITY STANDARDS AND MANAGEMENT
PRACTICES AS SET FORTH BY LOCAL, STATE AND FEDERAL
AGENCIES.
10. DURING THE PERIOD OF CONSTRUCTION, THE CONTRACTOR
IS RESPONSIBLE FOR ALL EROSION AND SEDIMENT CONTROL
MEASURES.  SAID MEASURES SHALL BE INSPECTED WEEKLY
AND AFTER EACH RAINSTORM AND DURING A MAJOR STORM
EVENT.  ACCUMULATED DEPOSITS OF SEDIMENT AND SILT
SHALL BE PERIODICALLY REMOVED FROM THE UPSTREAM SIDE
OF THE EROSION AND SEDIMENT CONTROL BARRIERS, AND
UPON ESTABLISHMENT OF PERMANENT SEEDING AND
MULCHING.  SUCH MATERIALS REMOVED SHALL BE SPREAD
AND STABILIZED IN NON-WETLAND AREAS WHICH ARE NOT
SUBJECT TO EROSION, OR WHICH ARE NOT TO BE PAVED OR
BUILT UPON.
11. HAY BALES, SILT FENCING AND OTHER EROSION AND
SEDIMENT CONTROL MEASURES SHALL BE REPAIRED,
CLEANED AND/OR REPLACED AS NECESSARY THROUGHOUT
THE CONSTRUCTION PERIOD IN ORDER TO MAINTAIN
COMPLETE AND INTEGRAL EROSION AND SEDIMENT CONTROL
PROTECTION.  ONCE IN PLACE ALL EROSION AND SEDIMENT
CONTROL FACILITIES AND MEASURES ARE TO REMAIN IN
PLACE AND IN PROPER CONDITION AND BE CONTINUOUSLY
MAINTAINED UNTIL FINAL GRADING HAS BEEN COMPLETED,
ALL DISTURBED AREAS UPGRADIENT OF SAID FACILITIES
HAVE BEEN PERMANENTLY STABILIZED AND ALL NEWLY
GRASSED AREAS HAVE HAD AT LEAST TWO MOWINGS.
FOLLOWING SUCH PERMANENT STABILIZATION, THE
FACILITIES SHALL BE DISMANTLED, REMOVED, AND DISPOSED
OF IN AN APPROVED MANNER.  ADDITIONAL EROSION AND
SEDIMENT CONTROL MEASURES BEYOND THOSE SHOWN ON
THE PLANS OR PRESCRIBED HEREIN SHALL BE PUT IN PLACE,
WHENEVER NECESSARY, TO ADDRESS FIELD CONDITIONS
AND/OR AS ORDERED BY THE TOWN.
12. DISTURBANCE OF THE LAND SHALL BE LIMITED TO THE
MINIMUM EXTENT NECESSARY TO COMPLETE THE PROPOSED
DEVELOPMENT.  ALL EXISTING TREES AND SHRUBS SHALL BE
CONSERVED WHERE POSSIBLE, EXCEPT THOSE WHOSE
REMOVAL IS REQUIRED TO PERFORM THE PROPOSED WORK.
THE LIMITS OF DISTURBANCE SHALL BE ESTABLISHED IN THE
FIELD PRIOR TO STARTING ANY ACTUAL CONSTRUCTION
ACTIVITIES AND SHALL BE GENERALLY AS DEPICTED BY THE
GRADING/SITE DEVELOPMENT DRAWINGS.
