To protect its Chesterfield Heights neighborhood, the City of Norfolk is working with VHB, its design partners, and industry owners to develop coastal defense strategies, including earthen berms, tide gates, raised roads, living shorelines, and floodwalls. To fit perimeter flood control features into existing industrial and residential infrastructure, the team had to consider the impact on adjacent waterbodies and tidal wetlands. The result will incorporate primary and secondary armor stone revetments and an extensive living shoreline that offsets necessary encroachments by creating more than four acres of tidal marsh. VHB worked with state and federal regulatory agencies to vet design decisions that will lay the groundwork for an efficient, predictable permit process.
