Construction Activities
Nighttime Utility Work
Crews are continuing nighttime utility work, which includes installation of conduit line for the new railroad bridge. This activity occurs weekdays from 9 p.m. to 5:30 a.m. and is expected to continue through the end of June. The adjacent communities may experience noise and lighting from the operation.
Track Work
Beginning as soon as Monday, June 16, crews are expected to begin installing railroad track foundations that will connect to the new railroad bridge south of San Juan Creek. Construction vehicles will access the site via Camino Capistrano and exit at Stonehill Drive using the access trail that runs along San Juan Creek.
Sheet Pile Installation
Crews completed installing sheet piles within the creek channel. An operation that began in early May, this work involved drilling 100-foot-long steel beams along the slope embankment. We appreciate the community’s patience throughout this process.
This work may be loud. Schedule is subject to change due to inclement weather or unforeseen operational issues.

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.
