- Where traffic counts are low, replace with low-water
- Install cables to restrain a bridge from being knocked off piers or abutments during floods or
- Install girder and deck uplift tie-downs to prevent their displacement from the substructure.
- Install Longitudinal Peaked Stone Toe Protection with nature planting, upstream of a failed abutment, to provide a stable floodplain bench for the protection of the abutment and the adjoining bridge approach. Consider other relevant Bio- engineering applications such as engineered logjams, log vanes or log bendway weir.
Marine Pier Ramps: If attached to decking, install open decking or floating decking with uplift resistant tie-downs and fasteners.
Roadways and Railways: Where shoulders are susceptible to overflow from adjacent water courses, stabilize shoulders and embankments with geotextile fabric and revetments.
Roadways: Use geotextile drainage blankets between the pavement section and subbase to strengthen subgrade.
Mechanical, Electrical, Plumbing (MEP) Components
- Provide seismic bracing for electrical lines, conduit, piping, duct-work, water heaters, and other MEP equipment. Components can be wall mounted, floor mounted, or suspended.
- Roof-Mounted Equipment: Secure to roof top via a continuous load path, using tie- downs, straps, or other anchoring systems that will resist expected wind forces.
- Elevate or dry floodproof components or systems vulnerable to flood damage, including equipment controls, electrical panels; heating, ventilation, and air conditioning/machinery rooms; emergency generators; and fuel tanks. When wiring cannot be elevated, replace with equipment suitable for submerged applications.
- Install switches, circuit isolation and/or quick connect capability to facilitate rapid connection of backup power for any damaged or susceptible mechanical and electrical components.
- Install camlocks, transfer switches, and electrical panels to facilitate the connection of portable emergency generators.
