TransportationCommission | 2007-07-25 | 4 | Mr. Dickenson noted that they eliminated the conflict of the Pulte building, and that while some of the hurdles still existed, he did not consider them to be insurmountable. He noted that the 23-mph curve was a challenge, and believed that it should be posted 5 mph below that. 7B. Project Update: for I-880/High Street Seismic Retrofit Project and 42nd Avenue/High Street Access Improvements. Discussion. Staff Khan presented the staff report. He noted that staff's concerns were related to access along frontage roads, although some of those concerns had been addressed by providing some direct access from the I-880 Southbound off-ramp that will connect directly to 42nd Avenue, providing better access to Alameda. Stanley Gee, project manager, Caltrans, made a presentation describing the seismic retrofit, and displayed the ongoing project on the overhead screen. He noted that Caltrans had determined that in the event of a major earthquake, the structures would be vulnerable to significant damage. They determined that it would be better to completely replace the structures, as detailed in the proposal. The cost of the project would be approximately $75 million, and the new structure would be designed to meet current highway standards, including lane width, shoulder width and ramp design. The new freeway will be somewhat wider than the existing structure, which currently has little to no shoulders. He noted that the biggest challenge would be to clear the right of way needed for the project, which would impact Home Depot. He added that there would be a significant impact to the parking lot area because of the widened freeway, reconstruction of the ramp, as well as the reconstruction of E. 8th Street. Caltrans was in the process of working out that issue with Home Depot, and the cities of Oakland and Alameda. The solution included eliminating a portion of E. 8th Street that would significantly reduce the impact of the Home Depot parking lot. Their intention was to not replace that portion of E. 8th Street. Mr. Gee noted that there would be a minor impact to the Shell gas station, and that the front of the property of the East Bay MUD pumping plant will have to be taken for the reconstruction of Oakport Street. He described the acquisition of the property formerly held by the Japanese engine company, as well as the Western Tool property. He advised that the goal of the project was the seismic retrofit of the structure, not adding lanes. An important feature of the project was the reconstruction of the interchange at 42nd Avenue and I-880. He noted that they were scheduled to start construction in early 2009, and that the actual construction period should take about four years. He displayed the actual staging of the project on the overhead screen. Transportation Commission July 25, 2007 Page 4 of 10 | TransportationCommission/2007-07-25.pdf |
