TAIT Environmental Services, Inc. performed fuel system services for El Dorado County Department of Transportation (DOT) in Placerville, CA. These services included installation of fueling dispensers, a new fuel management system, tank monitoring system, AST Piping, ground level fill boxes, and a syphon line. TAIT programmed and started up all systems, in addition to training the client on new features.
This project included approximately 1/3-mile total length of street reconfiguration, improvements to an existing raised median, a new traffic signal, abandonment of existing 8-inch ACP and 12-inch DIP City water lines, installation of a 800 LF of 16-inch water line, and relocation of SCE and AT&T main distribution service lines. It required the installation of new public storm drains, sewer, and water services to accommodate a future redevelopment project along Harbor Boulevard from Palm Street to Lampson Avenue in the City of Garden Grove. Engineering services required extensive research, review, and a potholing program for the installation of the new utilities and storm drain improvements within the existing six-lane Harbor Boulevard roadway.
The project included the rehabilitation of eight arterial and collector segments of roadway throughout the City of Pomona. This rehabilitation required analysis of the existing pavement conditions, recommendation of alternate rehabilitation methods by use of recycled pavement options, upgrading of 4 roadway segments for adding new bike lanes and the analysis, and replacement of all curb ramps along the project limits.
As part of a Design Build project for Golden State Water Company, TAIT provided the survey and design services for the replacement of 1,600 lineal feet of 14-inch steel water main in Normandie Avenue between Imperial Highway and 110th Street. Design engineering services included preparation of improvement plans for approximately one third of a mile total length of water main replacement, with cross connections to local streets, and new domestic water and fire services along Normandie Avenue.
TAIT provided design services for the replacement of 10,620 lineal feet of 4 and 6-inch water main in the Adams Hill neighborhood. The neighborhood is serviced by two pressure zones, and the existing water mains were 33 to 89 years old, were deteriorated and could not meet current fire flow demands. The residential streets were narrow, steep, and windy, and TAIT worked with Glendale Water & Power to determine the alignment that was the best fit for each roadway.
