MacArthur Avenue Traffic Calming Project

Project Description:

The County is evaluating installation of some type of traffic calming countermeasure to further reduce traffic speed on this roadway.  This half mile corridor connects residential, hospitals, and commercial districts.  The roadway is shared jurisdiction with City of San Jose and County.

Project Status:

The project is in preliminary design phase.

Community Meetings:

The first community meeting was held on October 16, 2019 where County provided some traffic calming countermeasures for MacArthur Avenue and received feedback from the community. 

The second community meeting was held on January 30, 2020. The County staff presented the recommended solution to address the speeding concern on MacArthur Ave. The initial three speed humps proposed by the County did not receive support from the residents. Only two of the three speed humps proposed had majority support. As a result, the third speed hump location was removed and instead, two speed display signs will be placed at that location, one in each direction of travel on MacArthur Ave. The final plan shown below reflects what was agreed to by the residents during the community meeting. The next step in this project is for the County to procure the materials and schedule installation of two speed humps and two speed display signs. After the project is completed and operational, the County staff agreed to do a post-project study to see if the 85th percentile speed has dropped. The results of the before/after speed study will be posted when available.
