Construction Activities
Retaining Walls
Crews are constructing five retaining walls adjacent to the bikeway bridge over San Juan Creek Trail. Activities include materials delivery, drilling, and installing steel beams. The longest retaining wall being constructed is within the rail right of way next to City Hall and the Santa Margarita Water District facilities. This wall will be approximately 470' long and 6' tall.
UPDATE: Concrete Pours for Railroad Bridge Improvements
Crews are continuing to construct bridge abutments for the new railroad bridge. This requires a day of intermittent concrete pours, which has been rescheduled to Monday, Feb. 3. To accommodate this activity, a series of concrete trucks will be accessing the construction site from Trabuco Creek Trail. During times when concrete trucks are on the trail, pedestrians and bicyclists will be briefly stopped by flaggers until the trail is clear.

Community Impacts
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 alarms. The alarms are required by state regulation.
