Drainage & Flood Control

The engineers in LNV’s Drainage and Flood Control Division have extensive experience in the analysis and design of both urban and riverine stormwater drainage systems. This experience encompasses all aspects of hydrologic and hydraulic engineering and includes: master drainage plans, floodplain mapping and management, regional and sub-regional detention facilities, and urban storm sewer system analysis and design. The engineers at LNV employ an extensive array of tools and technologies, including state-of-the-art two-dimensional hydraulic computer modeling for the analysis of challenging flooding scenarios.
