Project Description
DiazYourman & Associates (DYA) provided preliminary geotechnical services for the proposed Anaheim Canyon Metrolink Station Project in Anaheim, California. Planned improvements include constructing approximately 3,400 feet of second mainline track to the west of the existing single track, constructing a new 680-foot-long station platform located west of the existing track, extending the southern portion of the existing 510-foot-long station platform by 170 feet to meet the current Metrolink standard, constructing a retaining wall along the proposed platform on the west side, constructing improvements to the existing at-grade crossings of La Palma Avenue and Tustin Avenue to accommodate the proposed track, and relocating the existing house and antenna tower. The purpose of DYA's services was to provide preliminary geotechnical input during the preliminary engineering phase of the proposed Project. The scope of our services consisted of reviewing data, conducting a field exploration, performing laboratory tests on selected soil samples, performing engineering analyses to develop preliminary conclusions and recommendations, and preparing a geotechnical report. The primary geotechnical considerations include the presence of existing fill and fine-grained clayey soils. In addition, DYA conducted a Phase I Hazardous Waste Environmental Site Assessment to provide a planning document in general compliance with California Environmental Quality Act (CEQA) and National Environmental Policy Act (NEPA) guidelines for evaluating environmental impacts due to hazardous waste during construction and to identify recognized environmental conditions (RECs), historical recognized environmental conditions (HRECs), and controlled recognized environmental conditions (CRECs).
