WEC provides a wide range of floodplain management and hydraulic modeling and design. The firm’s president, Rick Woidt, is one of only 72 Certified Floodplain Managers in New York State. Our projects have included modeling of streams, culverts, closed stormwater systems, watersheds, bridge replacement hydraulic studies, stream restoration and stabilization, flood levees and closure structures, and interior (pumping) storm drainage systems. Our projects often deal with investigations of Flood Insurance Studies (FIS) requiring preparation of Conditional Letter of Map Revisions (CLOMR) or Letter of Map Revisions (LOMR). As such, we routinely coordinate with FEMA and their technical review contractors, offering us a comprehensive understanding of the administrative process. In addition, we have helped many of our clients obtain state and federal funding for disaster or pre-disaster mitigation projects.

WEC Floodplain Projects By Type

Representative Projects


Lourdes Hospital Flood Protection, Binghamton, NY

Lourdes Hospital Flood Protection, Binghamton, NY

This project involved a study and final design for providing a flood protection system for Our Lady of Lourdes Hospital in Binghamton, NY. The hospital, located in the 100-year floodplain of the Susquehanna River, has experienced chronic flooding problems at high river stages. The project investigated permanent alternatives to eliminate future flooding of the facility. The project included hydrologic and hydraulic modeling of the Susquehanna River, assessment of floodplain impacts, final design of concrete T-wall, closure structures and interior flood removal systems. The completed project successfully protected the facility from record Susquehanna River flooding in September of 2011.


Union-Endicott HS Flood Protection, Endicott, NY

Union-Endicott HS Flood Protection, Endicott, NY

This project involved a study and final design for providing flood protection for the Union-Endicott High School in Endicott, NY. This project investigated permanent alternatives to eliminate future flooding of the facility. The project included hydraulic modeling of the Susquehanna River, assessment of floodplain impacts, final design of concrete T-walls, closure structures and design of interior flood removal systems. The completed project successfully protected the school from record flooding in September of 2011.


Town and Village of Delhi, NY

Town and Village of Delhi, NY

This project involved developing a Local Flood Hazard Mitigation Plan for the Town and Village of Delhi to investigate its chronic flooding problems and their potential mitigation strategies. The LFHMP involved duplication of the FEMA HEC-RAS model, collecting field data to ensure duplicate model accuracy and developing a corrected model. Proposed mitigation strategies were modeled to understand the reduction of flooding inundation extents. Other mitigation strategies such as flood proofing and relocation, were explored to reduce flood damage. The project included sediment transport analysis.


Sidney Center Flood Channel Design, Sidney, NY

Sidney Center Flood Channel Design, Sidney, NY

Sidney Center has experienced chronic flooding due to insufficient hydraulic capacity along an existing tributary stream. Undersized cross culverts at road crossings exasperated flooding conditions. This project entailed designing a relocated channel and floodplain bench to convey floodwaters away from residential homes and properties. Understanding sediment transport behavior was a critical element in designing a relocated flood channel that would minimize future operating and maintenance costs.
