About this file

Written by GovTribe AI · May 28, 2026

This is a design specification document for the Stuttgart National Aquaculture Research Center Reservoir Embankment Rehabilitation project, issued by the U.S. Department of Agriculture Agricultural Research Service. The project is located in Stuttgart, Arkansas, and is associated with Design Contract No. 12405B21D0003 and Design Order No. 12405B23F0294.

The scope of work involves the rehabilitation and stabilization of the East Reservoir Levee at the Stuttgart National Aquaculture Research Center. Key design elements include: construction of a new levee section with a finished grade elevation of 200.2 feet; installation of 18-inch R200 rip rap slope protection with geotextile fabric over the water-facing side; 12-foot minimum top width with 1:3 slope ratios; placement of 3-inch ARDOT Class 7 crushed aggregate compacted to at least 95% maximum density per ASTM D698; and 8-inch fill or existing soil compacted to equivalent standards. The design also specifies removal and replacement of an existing 12-inch diameter reservoir outlet pipe through the levee, with detailed backfill and installation requirements. Additional work includes erosion control using silt fence, seeding and mulching of disturbed areas, and protection of existing facilities. The design drawings provide detailed typical sections, profiles, and specifications for all embankment rehabilitation components, with alignment information and specific elevation data for the 1.2-mile (approximately 12+34 station) East Reservoir Levee project.
