About this file

Written by GovTribe AI · Jun 27, 2025

These are technical design drawings for a U.S. Army Corps of Engineers levee setback rehabilitation project in the Ouachita River Basin, Louisiana. The solicitation (W912EE25BA007) covers levee rehabilitation at two sites (Sites 1 and 12), involving approximately 14.68 kilometers of levee reconstruction. The project includes comprehensive civil engineering work such as excavation, embankment construction, inspection trenching, gravel and stone surfacing, turf establishment, and environmental protection measures. The project is a total small business set-aside with an estimated construction value between $1,000,000 and $5,000,000, focusing on upgrading levee infrastructure in Ouachita and Caldwell Parishes. The detailed drawings include site location maps, cross-sections, right-of-way plans, utility disposition tables, and stormwater pollution prevention plans, providing comprehensive technical specifications for the proposed levee setback rehabilitation.

1. While the borings are representative of subsurface conditions at their respective locations and for their respective vertical reaches, local variations characteristic of the subsurface materials of the region are anticipated and, if encountered, such variations will not be considered as differing materially within the purview of the Contract Clause DIFFERING SITE CONDITIONS.

3. Consistency of cohesive soils shown on the boring logs is based on driller's log and visual examination and is approximate, except within those vertical reaches of the borings where shear strengths from unconfined compression test are shown.

10FIGURES TO LEFT OF BORING UNDER COLUMN "W OR D "

4. The detailed explanation of the Unified Soil Classification System is presented in ASTM D 2487, (2017) Classification of Soils for Engineering Purposes.

2. Ground water elevations shown on the boring logs represent ground water surfaces encountered in such borings on the dates shown. Absence of water surface data on certain borings indicates that no ground water data are available from the boring but does not necessarily mean that ground water will not be encountered at the locations or within the vertical reaches of such borings.

4. BUILDINGS CALLED OUT IN THE PLAN VIEW ARE NEAR EXPECTED ROW

LIMITS.

5. PLP AS SHOWN IN THE PLANS MEAN POWERLINE POLES.

6. THE EXISTING LEVEE ON EACH SITE WILL BE DEGRADED. THE EXISTING

LEVEE DEGRADE SHOULD BE SLOPED TO DRAIN TOWARDS THE RIVER.

7. THE EXISTING FENCE LOCATED ON SITE 1 SHALL BE REMOVED AND

REPLACED 25 FEET FROM THE TOE OF THE NEW LEVEE.

8. ON SITE 1 WE HAVE A VARYING NET SLOPE DUE TO VARYING ELEVATIONS ON

EACH END OF THE PROJECT. THE NET ELEVATION OF EACH END IS SHOWN IN

THE PROFILE VIEW.

9. THE INSPECTION TRENCH ON EACH SITE WILL BE DUG 6 FEET BELOW THE

EXISTING GROUND USING THE LEVEE SETBACK CENTERLINE.

10. THE GOVERNMENT ESTIMATES THAT THE CONTRACTOR WILL BE ABLE TO

USE APPROXIMATELY 12,400 CY OF IN-PLACE EMBANKMENT ON SITE 1 FROM

MATERIAL EXCAVCATED FROM THE REQUIRED LEVEE DEGRADE AT THE

RESPECTIVE SITE.

11. A SILT FENCE IS TO BE PLACED AT THE RIGHT OF WAY LIMITS.

12. INTERIM GRADE ELEVATION MUST BE MAINTAINTED DURING THE

CONSTRUCTION OF LEVEE SETBACK.

13. THE GAS LINE RUNNING THROUGH THE ACCESS ROAD ON SITE 1 IS OWNED

BY ATMOS ENERGY. THE LOCAL POC IS JAMES BAUM (318-664-1704).
