4th Bore Mitigation Areas Surveyed in Consultant’s Rockridge Walking Tour

Monday, July 5, 2010

Representatives from the Rockridge neighborhood, including Claremont Middle and Chabot schools, the city of Oakland Transportation Services Department, RCPC, Rockridge District Association (RDA), East Bay Bicycle Coalition (EBBC), North Hills Phoenix Association (NHPA), Fourth Bore Coalition (FBC) and consultants participated in the Oakland mitigation walking tour early in June.

The tour was to determine mitigative measures that would help offset impending noise and traffic expected to result from construction of the new tunnel and subsequent increased vehicle traffic on Hwy. 24.

The lengthy tour started at the Claremont and College Avenue intersection, proceeded along College Avenue to Manila Avenue, then cut over to Broadway to finish at Brookside. Along the way, participants explained intersection issues and worked with the consultants on pedestrian and bike improvements. Pedestrian crossing issues along Broadway and Claremont Avenues were also mentioned.

Installation of soundwalls is another project on the list. A noise study by consultant Wilson Ihrig, commissioned by Caltrans as part of the Oakland settlement, ascertained sound levels along Hwy. 24 residences between Hwy. 13 and I-580. Many locations qualify for soundwalls based on noise levels equal to or greater than 65 dB, including residences along Keith, Locksley, and Miles avenues.*

RCPC has submitted background material on potential projects to the city of Oakland. During the summer, the City plans to develop project fact sheets for the public meetings.

The RCPC September Town Hall will be the Rockridge meeting venue for the public meetings. Watch for more information in the September Rockridge News. For additional information and breaking news, visit www.rockridge.org.
