Engineering & Design to Mitigate Riverine & Coastal Flooding
Identify and address flood hazard areas in existing communities and proposed developments
WithersRavenel specializes in comprehensive flood studies and is committed to effective floodplain management. Using detailed hydrology and hydraulic modeling, we design new or upgraded stream crossings for vehicles, pedestrians, and utilities in areas with a history of flooding or in preparation for future upstream development. The crossings can include customized culvert designs fitted to the unique characteristics of a stream, creek, or river. Floodplain management techniques play a key role in these projects to help protect communities from potential hazards.
Comply with FEMA documentation requirements
Projects located within floodways require an engineering analysis to determine if the project will have any impacts, particularly adverse ones. WithersRavenel’s stormwater engineers can prepare No-Impact Certifications and No-Rise Certifications as appropriate for your project. In addition, floodplain management regulations guide our approach to ensure all requirements are met throughout the design and permitting process.
Inform prospective buyers, sellers, and developers of potential flood risks
We work closely with clients, local communities, and FEMA to modify Flood Insurance Rate Maps (FIRM) to accurately represent existing conditions or new developments. Moreover, floodplain management provides essential information to stakeholders as development plans progress and community needs evolve.
