GENERAL EROSION AND TURBIDITY CONTROL NOTES

1. FURNISH, INSTALL, AND MAINTAIN TURBIDITY AND EROSION CONTROL MEASURES AND

MAINTAIN TURBIDITY AND EROSION CONTROL MEASURES AROUND THE LIMITS OF

CONSTRUCTION IN ORDER TO PREVENT ANY EROSION OR SEDIMENTATION IN ADJACENT

WETLANDS AND OTHER SURFACE WATERS.

2. FURNISH, INSTALL, AND MAINTAIN TURBIDITY BARRIERS IN ALL PERMANENT BODIES OF WATER

REGARDLESS OF WATER DEPTH AROUND THE WORK AREA DURING ALL CONSTRUCTION

ACTIVITIES. THE CONTRACTOR HAS THE OPTION TO ENCLOSE THE ENTIRE WATERSIDE OF THE

SITE, WITHIN THE LIMITS OF DISTURBANCE, OR TO INSTALL AND MOVE THE TURBIDITY

BARRIERS IN STAGES.

3. PRIOR TO CONSTRUCTION, THE CONTRACTOR IS RESPONSIBLE FOR RECEIVING APPROVAL OF

TURBIDITY CONTROL PLAN FROM THE APPLICABLE REGULATORY AGENCIES. REFER TO THE

PROJECT PERMIT APPROVALS AND PERMIT CONDITIONS FOR AGENCIES REQUIRING SUCH

REVIEW AND APPROVAL. QUESTIONS CONCERNING APPROPRIATE TECHNIQUES SHOULD BE

ADDRESSED TO THOSE AGENCIES AND/OR DISCUSSED WITH THE CONTRACTING OFFICER.

4. THE APPROPRIATE TURBIDITY AND EROSION CONTROL METHODOLOGIES SELECTED BY THE

CONTRACTOR FOR THIS PROJECT SHOULD BE MADE FOLLOWING ASSESSMENT OF THE PLANS

AND PROJECT SITE SPECIFIC FACTORS AND AFTER CONSULTATIONS AS NEEDED WITH THE

CONTRACTING OFFICER AND APPROPRIATE AGENCIES. THE CONTRACTOR WILL BE

RESPONSIBLE FOR OBTAINING ANY AND ALL NECESSARY PERMITS FOR SUCH ACTIVITY;

SEVERAL FACTORS TO CONSIDER ARE LISTED BELOW:

A. AMBIENT GROUND WATER LEVELS

B. ACTUAL RAINFALL AMOUNTS AND TIME OF YEAR RELATIVE TO NORMAL RAINY SEASON

C. PROXIMITY TO WETLANDS, WATER BODIES, OR OFFSITE PROPERTIES

D. CLASS DESIGNATION OF RECEIVING WATER BODY (OUTSTANDING FLORIDA WATERS,

SHELLFISH HARVESTING AREAS, ETC.)

E. DENSITY, TYPE, AND PROXIMITY OF UPLAND VEGETATION TO BE RETAINED DURING

CONSTRUCTION (FOR USE AS POSSIBLE FILTRATION AREAS)

F. EXISTING TOPOGRAPHY AND DIRECTIONS OF SURFACE FLOW

G. TYPE OF EQUIPMENT USED

H. PROJECT TYPE

I. DURATION OF CONSTRUCTION ACTIVITIES

J. AMBIENT QUALITY OF SURFACE AND GROUNDWATER

K. TEMPORARY STOCKPILE LOCATIONS AND DIMENSIONS

5. AT THE ONSET OF CONSTRUCTION, THE CONTRACTOR, AS THE PARTY RESPONSIBLE FOR

IMPLEMENTATION OF THE EROSION AND SEDIMENT CONTROL PLAN, MUST ASSESS THE ABOVE

CONDITIONS AND FACTORS AND SELECT THE APPROPRIATE METHODS OF PROTECTION.

CONSTRUCTION SEQUENCING SHOULD BE PLANNED PRIOR TO INITIATION TO PROVIDE

ADEQUATE PROTECTION OF WATER QUALITY.

6. ADDITIONAL EROSION AND TURBIDITY CONTROL MEASURES OTHER THAN THOSE PRESENTED

MAY BE REQUIRED DUE TO CONSTRUCTION SEQUENCING AND UNFORESEEN WEATHER

CONDITIONS. THESE ADDITIONAL EROSION AND TURBIDITY CONTROL MEASURES, INCLUDING

EXTRAS FOR MATERIALS AND LABOR, MUST BE PROVIDED BY THE CONTRACTOR.

7. COORDINATE THE INSTALLATION OF TEMPORARY EROSION CONTROL BARRIERS WITH THE

CONSTRUCTION OF PERMANENT EROSION CONTROL FEATURES TO THE EXTENT NECESSARY

TO ASSURE EFFECTIVE AND CONTINUOUS CONTROL OF EROSION AND WATER QUALITY

THROUGHOUT THE LIFE OF THE CONSTRUCTION PHASE.

8. THE TYPE OF EROSION CONTROL BARRIERS USED MUST BE GOVERNED BY THE NATURE OF

THE CONSTRUCTION OPERATION AND SOIL TYPE THAT WILL BE EXPOSED. SILTY AND CLAYEY

MATERIAL MAY REQUIRE SOLID SEDIMENT BARRIERS TO PREVENT TURBID WATER DISCHARGE,

WHILE SANDY MATERIAL MAY NEED ONLY SILT SCREENS OR HAY BALES TO PREVENT EROSION.

DIVERSION DITCHES OR SWALES MAY BE REQUIRED TO PREVENT TURBID STORMWATER

RUNOFF FROM BEING DISCHARGED TO WETLANDS OR SURFACE WATERS. IT MAY BE

NECESSARY TO EMPLOY A COMBINATION OF BARRIERS, DITCHES, AND OTHER

EROSION/TURBIDITY CONTROL MEASURES IF CONDITIONS WARRANT.

9. SHEET FLOW OF NEWLY FILLED OR SCRAPED AREAS MAY BE CONTROLLED OR CONTAINED BY

THE USE OF BRUSH BARRIERS, DIVERSION SWALES, INTERCEPTOR DITCHES OR LOW BERMS.

FLOW SHOULD BE DIRECTED TOWARD AREAS WHERE SEDIMENTS CAN SUFFICIENTLY SETTLE

OUT.

10. STABILIZE EXPOSED SOILS AS SOON AS POSSIBLE, ESPECIALLY SLOPES LEADING TO

WETLANDS. STABILIZATION METHODS INCLUDE SOLID SOD, SEEDING AND MULCHING OR

HYDROMULCHING TO PROVIDE A TEMPORARY OR PERMANENT GRASS COVER MULCH

BLANKETS, FILTER FABRICS, ETC., CAN BE EMPLOYED TO PROVIDE VEGETATIVE COVER.

11. IMPLEMENT STORM DRAIN INLET PROTECTION (HAY BALES OR GRAVEL) TO LIMIT

SEDIMENTATION WITHIN THE STORMWATER SYSTEM. PERFORM INSPECTIONS AND PERIODIC

CLEARING OF SEDIMENTS THAT WASH OUT INTO THE STREETS UNTIL ALL SOIL IS STABILIZED.

12. RESTRICT WATER DISCHARGE VELOCITIES FROM IMPOUNDED AREAS AND TEMPORARY

SEDIMENTATION BASINS TO AVOID SCOURING IN RECEIVING AREAS.

13. VEHICLE OR EQUIPMENT WASHDOWN AND FUELING AREAS WILL BE SUFFICIENTLY REMOVED

FROM WETLANDS OR OFFSITE AREAS.

14. FUGITIVE DUST CONTROLS (PRIMARILY BY USING WATER SPRAY TRUCKS) SHALL BE

EMPLOYED AS NEEDED TO CONTROL WINDBORN EMISSIONS.

15. ONGOING INSPECTIONS AND PERIODIC MAINTENANCE BY THE CONTRACTOR SHALL OCCUR

THROUGHOUT CONSTRUCTION AS NECESSARY TO ENSURE THE ABOVE METHODS ARE

WORKING SUITABLY. THIS MAY BE NEEDED DAILY, IF CONDITIONS SO WARRANT. THE

CONTRACTOR IS ENCOURAGED TO OBTAIN AND THOROUGHLY REVIEW THE FLORIDA

DEVELOPMENT MANUAL: A GUIDE TO SOUND LAND AND WATER MANAGEMENT, WHICH WAS

DEVELOPED BY THE STATE OF FLORIDA DEPARTMENT OF ENVIRONMENTAL PROTECTION IN

1988 AND PROVIDES DISCUSSIONS OF RECOMMENDED TECHNIQUES AND DESIGN AND

TECHNICAL STANDARDS.

16. THE CONTRACTOR WILL PERFORM DAILY INSPECTIONS OF ALL ON-SITE WETLANDS WITHIN THE

CONSTRUCTION AREA TO ENSURE THAT WATER LEVELS WITHIN THOSE WETLANDS ARE NOT

EXCESSIVELY IMPOUNDED PRIOR TO THE TIME WHEN THE PERMITTED CONTROL STRUCTURE

OR OUTFALL IS BUILT. WATER LEVELS SIGNIFICANTLY ABOVE NORMAL SHOULD BE

CORRECTED AT A FREQUENCY THAT PREVENTS A CHANGE IN THE VEGETATIVE CHARACTER

OR HEALTH OF ANY WETLANDS.

17. CONTRACTOR NEEDS TO FULLY COMPLY WITH THE U.S. ARMY CORPS OF ENGINEERS AND THE

FLORIDA DEPARTMENT OF ENVIRONMENTAL PROTECTION "SEA TURTLE AND SMALLTOOTH

SAWFISH CONSTRUCTION CONDITIONS".

18. ADHERE TO FFWCC STANDARDS FOR MANATEE CONDITIONS AND SMALLTOOTH SAWFISH FOR

IN-WATER WORK.
