Project Scope
DJ&A was tasked with development and analysis of three reconstruction alternatives, each with plans, specifications and estimates for the project. The PS&E incorporates maps, horizontal and vertical alignments indicating major structures, typical roadway sections, preliminary earthwork quantities, cost estimates, design narrative and water quality monitoring. The project also requires a NEPA (National Environmental Policy Act) Environmental Assessment (EA) document showing the impacts on fisheries, wetlands, cultural resources, threatened and endangered species, wild and scenic rivers and the high visual quality of the area. In addition, work includes a public record investigation, Preliminary Wetlands Assessment, Biological Resources Report, Biological Assessment with specific recommendations for avoidance, protection and mitigation. There will also be an assessment of existing structures with recommendations for structure modifications, a Hydraulic Reconnaissance Memorandum, a conceptual hydraulic design addressing water quality impacts and mitigation.
