EROSION AND SEDIMENT

CONTROL NOTES


Consultants

PROJECT NOTES:

1. THE CONTRACTOR ULTIMATELY SELECTED SHALL COMPLY WITH

THE DEEP PERMIT FOR THE DISCHARGE OF STORMWATER AND

DEWATERING WASTEWATERS ASSOCIATED WITH

CONSTRUCTION ACTIVITIES, AND BE RESPONSIBLE FOR

OVERSEEING THE INSTALLATION AND MAINTENANCE OF ALL

SEDIMENTATION AND EROSION CONTROL MEASURES.

CONTRACTOR WILL BE RESPONSIBLE FOR PREPARING AND

OBTAINING THIS PERMIT, AND FOR COMPLIANCE DURING

CONSTRUCTION.

2. THE CONTRACTOR ULTIMATELY SELECTED WILL BE REQUIRED

TO PROVIDE A SUBMITTAL WHICH PROVIDES DETAILS,

PROCEDURES, AND WORK METHODS TO PROPERLY EXECUTE

THE WORK, PROTECT THE ENVIRONMENT, AND MINIMIZE

DISRUPTION TO ADJACENT PROPERTIES AND PUBLIC

FACILITIES. THIS PLAN SHALL INCLUDE, BUT IS NOT LIMITED TO:

· PREPARATION OF VARIOUS PLANS AND OTHER WRITTEN

SUBMITTALS REQUIRED FOR PROPER CONTROLS

DURING CONSTRUCTION.

· IDENTIFICATION OF STAGING AND STOCKPILE AREAS.

· LOCATION AND PLACEMENT OF ANTI TRACKING PADS TO

CONTROL SEDIMENTS.

· SEQUENCING OF PLACEMENT AND REMOVAL OF

TURBIDITY CURTAINS THAT WILL BE INSTALLED IN

PHASES ALONG DUNE AND BEACH NOURISHMENT

SECTIONS IN A “ROLLING” FASHION.

· TRUCK ROUTES AND ACCESS POINTS FOR PORTIONS OF

THE PROJECT REQUIRING OVERLAND DELIVERY OR

REMOVAL OF MATERIAL.

· FOR MATERIAL DELIVERED OR REMOVED FORM SITE

USING WATERBORNE MEANS (BARGES, ETC.) A DETAILED

SUBMITTAL WILL BE REQUIRED.

3. SEDIMENTATION AND EROSION CONTROL MEASURES ARE

PROPOSED TO ADEQUATELY CONTROL THE ACCELERATED

EROSION AND SEDIMENTATION AND REDUCE THE DANGER

FROM STORMWATER RUNOFF AT THE SITE. THE RUNOFF SHALL

BE CONTROLLED BY THE INTERCEPTION, DIVERSION, AND SAFE

DISPOSAL OF PRECIPITATION. RUNOFF SHALL ALSO BE

CONTROLLED BY STAGING CONSTRUCTION ACTIVITY AND

PRESERVING NATURAL VEGETATION WHENEVER POSSIBLE.

4. EXISTING DUNE VEGETATION SHALL BE PROTECTED AND ONLY

THAT CLEARING AND GRUBBING THAT IS ABSOLUTELY

NECESSARY FOR THE PROPOSED DUNE CONSTRUCTION,

DRAINAGE INSTALLATION, AND BEACH NOURISHMENT SHALL BE

PERFORMED. ALL DISTURBED AREAS SHALL BE RESTORED TO

THEIR ORIGINAL CONDITION AND CONTOUR, UNLESS

OTHERWISE INDICATED ON THE PLANS. THE CONTRACTOR

SHALL TAKE SPECIAL CARE WITH HIS DUNE CONSTRUCTION,

BEACH NOURISHMENT, AND DREDGING METHODS AND SHALL

COMPLY WITH SPECIFICATIONS FOR EROSION AND SEDIMENT

CONTROLS.

5. ALL AREAS SHALL BE PROTECTED FROM SEDIMENTATION

DURING AND AFTER DREDGING, INCLUDING THE

CORRESPONDING STORAGE AND HANDLING AREAS FOR

DREDGED SEDIMENT. STOCKPILES MUST BE ADEQUATELY

PROTECTED WITH HAY BALES AND/OR FILTER FABRIC FENCE AS

INDICATED.

6. FREQUENTLY INSPECT EROSION CONTROLS. REPAIR/REPLACE

DEFICIENT EROSIONS CONTROLS PROMPTLY, AS NEEDED.

7. STONE STABILIZED VEHICLE ANTI-TRACKING PADS SHALL BE

LOCATED AT POINTS OF VEHICULAR INGRESS AND EGRESS

FROM THE CONSTRUCTION SITE TO REDUCE TRACKING OR

FLOWING OF SEDIMENT INTO PUBLIC RIGHTS-OF-WAY. FILTER

FABRIC SHALL BE PLACED ON SUBGRADE PRIOR TO

PLACEMENT OF STONE. STONE SHALL BE PLACED TO THE

DIMENSIONS SHOWN ON THE PLAN. PERIODIC TOP DRESSING

WITH ADDITIONAL STONE OR ADDITIONAL LENGTH, AS

CONDITIONS DEMAND, MAY BE REQUIRED TO ENSURE THAT THE

ENTRANCE FUNCTIONS AS INTENDED. PUBLIC ROADWAYS

SHALL BE CLEANED OF DIRT AND DEBRIS AS NECESSARY, OR

AS DIRECTED BY THE ENGINEER.

8. IN ALL AREAS, REMOVAL OF TREES, BUSHES AND OTHER

VEGETATION, AND DISTURBANCE OF THE SOIL, IS TO BE KEPT

TO AN ABSOLUTE MINIMUM WHILE ALLOWING PROPER

DEVELOPMENT OF THE SITE.

9. DURING DREDGING OPERATIONS REQUIRED FOR INSTALLATION

OF DRAINAGE, ROCK CORE BASE, AND OTHER COMPONENTS,

THE AREA AND DURATION OF SEDIMENT EXPOSURE SHALL BE

MINIMIZED, AND THE SEQUENCE OF DREDGING OPERATION

SHALL ACT TO MINIMIZE THE EXPOSURE.

10. ALL SEDIMENTATION AND EROSION CONTROL DEVICES SHALL

BE INSPECTED DURING CONSTRUCTION AND THE CONTRACTOR

SHALL MAINTAIN AND MAKE REPAIRS AND REMOVE SEDIMENT IF

IT HAS ACCUMULATED AND RENDERED THE SEDIMENT

CONTROL NON-FUNCTIONAL. THE CONTRACTOR SHALL IN

ADDITION MAINTAIN AND MAKE REPAIRS AND REMOVE

SEDIMENT AS REQUESTED BY THE ENGINEER. THE

CONTRACTOR SHALL CLEAN SEDIMENT AND DEBRIS FROM ALL

DRAINAGE STRUCTURES AND PIPES AT THE COMPLETION OF

THE DREDGING ACTIVITIES AND AS REQUESTED BY THE

ENGINEER TO KEEP THE DRAINAGE SYSTEM PROPERLY

FUNCTIONING.
