Biological Surveys; Wetland delineation; Report preparation

DRC prepared a biological survey for the Valley Elderberry Longhorn Beetle, a wetlands delineation, and a report for the Central Federal Lands Highway Division, the Federal Highway Administration (FHWS) of the Department of Transportation. The work was performed on portions of California Forest Highway 105, Marysville Road, in Yuba County.

Our staff performed the species survey and its elderberry food plant at all survey locations. We delineated wetlands at the Oregon House location, following the Corps of Engineers’ 1987 delineation manual and routine one-site determination methods. Our team drew the wetland boundaries on project mapping the FHWA supplied and prepared and submitted a separate Data Form No. 1 for each plant community type within the survey area.

Reports outlined the precise location of all elderberry shrubs, their height and diameter, the presence of adult exit holes and the general condition of the plants; measured the diameter of the stems at ground level; and included a map indicating the major vegetation communities at each site where elderberry plants were found.

Environmental Impact Statement; Environmental Assessment; Biological Assessment

DRC conducted an Environmental Assessment (EA) and Biological Assessment (BA), as required by the National Environmental Policy Act, for the testing of the Advanced Amphibious Assault Vehicle (AAAV) prototypes. The EA and BA addressed the proposed testing of two prototypes at two Camp Pendleton off-shore water locations in addition to a 30-mile Pacific Ocean transit. Landing areas and emergency water exit points during water testing included base beaches. DRC staff systematically described the environmental resources present and possible effects of the proposed action.

Resources addressed land use, cultural, socioeconomic and environmental justice. Information on the following resources were provided and specifically addressed in the EA, specifically:

  • Air and noise: All air emissions data, noise impact studies for the project were included where applicable (matrix, text, impacts, conclusions, appendix, etc.). DRC staff identified all significant noise resources in the area generated or affected (directly or indirectly).
  • Biology: DRC staff addressed the action’s timing (seasonal perspective) for the planned test events and analyzed if and how it would impact any vegetation/wildlife, including the Marine Mammal Protection Act. DRC detailed potential for impacts to marine mammals, based on available audiometric data and assumptions the marine mammal scientific community accepts for those species without audiograms and addressed the potential for acoustic harassment, physical injury, entanglement, exposure to hazardous materials/wastes, ingestion, disturbance of migration, disturbance to feeding areas, disturbance to haul out areas (for pinniped species), and any other potential impacts that could occur to marine mammals. DRC calculated impact probability and recommended mitigation measures.

Design - Build; Appraisal Level Study Phase; Feasibility Studies/Traffic Control Plans; Feasibility Technical Memorandums; Design and Specifications; Permitting and Public Affairs

DRC provided design-build services for the Tracy Fish Facility Improvement Program (TFFIP) in Tracy, California, for the Federal Department of the Interior’s Bureau of Reclamation (BoR). The program develops and implements new fish collection, holding, transport, and release technology to improve fish protection at major water diversions in the South Delta region of the state’s Central Valley. TFFIP funds research activities that are performed by BoR fishery scientists and engineers.

The project involved constructing a Tracy Fish Test Facility (TFTF) on the North side of a canal intake in California’s Contra Costa and Alameda counties. DRC developed a total project baseline schedule that showed each phase and the tasks to accomplish each phase as part of the Tracy Fish Test Facility Final Environmental Assessment & Initial Study (EA/IS).

DRC collected and analyzed data to estimate impacts from the proposed project to air quality, traffic patterns, and traffic safety. Our team identified alternative mitigation/impact reduction measures and drafted an appraisal-level comprehensive traffic control plan. DRC received input from representatives of Contra Costa and Alameda counties on the draft traffic control plan and briefed BoR on the appraisal’s technical memorandum and the traffic control plan. DRC conducted a feasibility-level study that included on-the-ground data collection, searching files, databases and libraries, obtaining permits for road closures, and performing modifications associated with the project’s construction.

DRC’s designs and safety impacts ensured functional and attractive facilities that were practical, economical, and maintainable. DRC worked with Alameda and Contra Costa counties to obtain construction permits for BoR’s signature for encroachment permits, road closures, road improvements and implementation of traffic mitigation and control measures.
