About this file

Written by GovTribe AI · Jan 22, 2025

This is a set of contract drawings showing the dredging locations, coordinates, and placement sites for the West Coast Hopper Maintenance Dredging 2025 project (Solicitation W9127N25B0005) by the US Army Corps of Engineers Portland District. The drawings detail maintenance dredging at multiple locations including Humboldt Bay (CA), Coos Bay (OR), Lower Columbia River (OR/WA), and Mouth of Columbia River, with specific dredging depths, placement sites, and survey coordinates provided for each location.

The drawings include detailed bathymetric survey data, dredging transition zones, placement site coordinates, and cross-sections showing required depths and maximum pay depths. Key features include placement sites like the Shallow Water Site, North Jetty Site, Deep Water Site DZ-14, and South Jetty Site with their corresponding grid cells and coordinates. The drawings are dated between July-December 2024 and include approval signatures from USACE Portland District leadership. Specific technical details include required dredging depths ranging from 37-55 feet MLLW with 2-5 feet of paid overdepth depending on location, and precise coordinates for all dredging areas and placement sites.
