This document consists of final design and engineering drawings for the Assunpink Rehabilitation Design project (ASNPK), developed for the USDA Natural Resources Conservation Service (NRCS) by the Aterra-Schnabel Joint Venture. The plans outline structural, geotechnical, civil, and environmental engineering specifications to rehabilitate the Assunpink dam, spillway, and associated infrastructure in New Jersey. Key components of the design files include: - **Site Layouts and Profiles:** Detailed baseline alignments, coordinate point tables, and elevations for the proposed dam embankment, auxiliary spillway (ASW), and principal spillway (PSW). - **Geotechnical Profiles:** Subsurface geologic sections detailing existing soil conditions (such as fill, silty sand, and clay layers) across the dam embankment, proposed toe drain, and auxiliary spillway. - **Structural Details:** Construction plans and profiles for the proposed roller-compacted concrete (RCC) auxiliary spillway, starter walls, and a detailed steel reinforcement schedule. - **Maintenance and Repairs:** Repair specifications for the existing concrete impact basin, riser coatings, and details for chain-link fence installations and concrete anchoring. - **Soil Erosion and Sediment Control (SESC):** Multi-phase environmental plans detailing sediment barriers, filter bags, erosion control matting, and native vegetative plantings (such as Black Gum, Sweetgum, and Southern Arrowwood) to stabilize the site during and after construction. These comprehensive engineering drawings serve as the technical foundation for bidding, regulatory compliance, and physical execution of the rehabilitation project.
