PLEASE NOTE:  Sitewide work restarted under appropriate COVID-19 protocols for construction projects, as recommended by the Centers for Disease Control and Prevention and local health officials.

General Construction Information

Construction site access is via El Camino Real at Cambridge Avenue, Middle Avenue and Partridge Avenue.

Roadway flaggers will be on duty as needed to direct trucks and equipment entering and leaving the construction site.

There is noise and dust associated with construction operations. Noise is mitigated as much as possible; however, intermittent noise disruptions can occur. Construction requirements will be met per code. Dust control operations, via water spray, coincide with these operations.

Construction Hours

Construction hours are compliant with the City of Menlo Park’s Construction Policy.

Please note that there may be instances where Project construction activities take place during the evening and/or weekends when deemed necessary to reduce construction impacts on traffic along El Camino Real. This will be done with the required necessary approval from the City of Menlo Park.
