Construction Activities
Sheet Pile Installation
The installation of steel beams, also referred to as “sheet piles,” is underway. This work requires drilling 100-foot-long sheet piles along the slope embankment within San Juan Creek using vibratory and diesel hammers. The surrounding community may be impacted by noise and vibration from this activity. This work is ongoing through mid-June, between 6 a.m. and 5 p.m., Monday through Friday.
This work may be loud. Schedule is subject to change due to inclement weather or unforeseen operational issues.

Community Impacts
Flaggers will intermittingly stop pedestrians and bicyclists as equipment is being moved and construction on the new railroad bridge around the bike path continues. Once the area is cleared, trail users may proceed.
A full trail closure is expected in June. More details will be available in future communications.
Train Horns
Federal Railroad Administration (FRA) guidelines require all trains to sound their horns when workers are present, in emergency situations or when there are trespassers on or around railroad tracks. This federal mandate applies to construction zones. As a result, for the safety of construction workers, train crews and passengers, and the public, horns will be sounded when trains pass through the area.
Additional Impacts
The public and businesses adjacent to the work area may experience noise and vibration from demolition and drilling activities as well as light from construction operations. Noise may also be generated from construction equipment back-up alarm. The alarms are required by state regulation.
