About this file
These are technical drawings (sheets C-501 and C-502) from the US Army Corps of Engineers Vicksburg District for a levee enlargement and berms project in Tensas Parish, Louisiana. The detailed drawings provide specific construction specifications for storm water pollution prevention, including silt fence installation details, hay wattle placement, construction entrance/exit details, settlement plate placement, and levee benching techniques. The drawings specify critical environmental protection controls such as erosion prevention measures, including maximum spacing requirements for silt fences, wattle placement intervals, anchoring techniques, and guidelines for managing sediment runoff during construction. The documents are part of a solicitation (W912EE-25-R-A007) specifically targeted at pre-qualified MATOC contractors for Mississippi River Levee construction, with recommended implementation in March 2025.

1. INSPECT AND REPAIR FENCE AFTER EACH STORM EVENT AND REMOVE SEDIMENT WHEN
NECESSARY.
2. REMOVED SEDIMENT SHALL BE DEPOSITED TO AN AREA THAT WILL NOT CONTRIBUTE
SEDIMENT OFF-SITE AND CAN BE PERMANENTLY STABILIZED.
3. SILT SCREEN FENCE SHALL BE PLACED ALONG SLOPE CONTOURS TO MAXIMIZE PONDING
EFFICIENCY.
4. CONTRACTOR SHALL BEGIN EXCAVATION OPERATIONS AT A MINIMUM 10 FOOT OFFSET
INSIDE THE BORROW AREA RIGHT OF WAY AS SHOWN.
5. THE STATIONING SHOWN ON THE SITE PLAN REFERS TO THE NEW LEVEE CENTERLINE
STATIONING.
6. OVERBANK PUMPING IS PROHIBITED. ENCLOSED CONDUITS SHALL BE USED TO PUMP ALL
EXCESS WATER FROM THE BORROW AREA AS DEEMED NECESSARY TO APPROVED
DISCHARGE LOCATIONS. INLET LINES SHALL ONLY PUMP WATER FROM THE SURFACE OF
THE BORROW AREA, AND POINTS OF DISCHARGE SHALL EXTEND AT A MINIMUM OF
20-FEET PERPENDICULAR FROM THE WATER'S EDGE OF THE RECEIVING BODY BELOW THE
SURFACE (5' MINIMUM OR BOTTOM) AS TO INHIBIT EROSION. ADDITIONAL EROSION
MEASURES SHALL BE UTILIZED AT ANY POINT IN WHICH IMMEDIATE ACTION IS NEEDED TO
MAINTAIN EXISTING SOIL STABILITY.
7. THE ENVIRONMENTAL PROTECTION CONTROLS SHOWN IN THE CONTRACT DRAWINGS
MAY NOT FULLY ADDRESS ALL CONCERNS AND PERMIT REQUIREMENTS, BUT ARE
PROVIDED TO ESTABLISH A MINIMUM LEVEL OF PROTECTION REQUIRED AT ALL TIMES. THE
CONTRACTOR SHALL CONSIDER HIS WORK OPERATIONS, METHODS, AND CURRENT SITE
CONDITIONS TO DEVELOP A COMPLETE PLAN, INCLUDING ADDITIONAL PROTECTION
MEASURES AS REQUIRED, TO ASSURE ADEQUATE PERFORMANCE AND COMPLIANCE WITH
ALL CONTRACT DOCUMENTS, REGULATIONS, AND PERMITS. REFERENCE SECTION 01 57
20.00 09 ENVIRONMENTAL PROTECTION AND SECTION 01 57 23.00 09 STORM WATER
POLLUTION PREVENTION PLAN FOR ADDITIONAL REQUIREMENTS.
8. THE CONTRACTOR SHALL EMPLOY THE USE OF ADDITIONAL EROSION CONTROL BMP
MEASURES TO MITIGATE THE DISTURBANCE OF LOCATIONS WHERE CLEARING AND
GRUBBING IS TO OCCUR ON THE LANDSIDE TOE OF THE LEVEE.
9. IN THE EVENT THAT ADJACENT RECEIVING WATER BODIES ARE UNAVAILABLE FOR
UNWATERING, UNWATERING SHALL BE ADMINISTERED ACCORDING TO ALTERNATIVE BMP
PRACTICES APPROVED BY THE CONTRACTING OFFICER AND LDEQ. APPROVED DISCHARGE
LOCATIONS ARE NOT DEFINED ON THE PLANS AND SHALL BE COORDINATED WITH THE
LANDOWNER AND THE CONTRACTING OFFICER.
10. MINIMUM RECOMMENDED PLACEMENT INTERVAL BETWEEN WATTLE DITCH CHECK IS 100'
UNLESS SHOWN OTHERWISE ON THE PLANS OR EROSION CONTROL PLAN APPROVED BY
THE CONTRACTING OFFICER.
11. ANCHORING WOOD STAKES SHALL BE SIZED, SPACED, DRIVEN, AND BE OF A MATERIAL
THAT EFFECTIVELY SECURES THE CHECK. STAKE SPACING SHALL BE A MAXIMUM OF THREE
FEET. ALL NON-DEGRADABLE MATERIALS SHALL BE REMOVED WHEN NO LONGER NEEDED.
12. TRENCHING OF WATTLES MAY BE NECESSARY IF PIPING BECOMES EVIDENT.
13. WATTLES SHOULD NOT BE USED IN HARD BOTTOM CHANNELS.
