The domes on the river are a busy place. They were spared damage from the flooding San Juan River due to sound local engineering work and architectural design.
The design raised the ground level by 10 feet, and grant funding paid for the design, foundational, and infrastructure work. Maintenance work is also underway.
Visit the Riverwalk to observe the progress.
No luck involved, just sound local engineering and hard work.
