SERVICES: PUBLIC WORKS: FLOOD CONTROL

Our approach to flood control design focuses on balancing the natural resources with the structural or man-made features.  The environmental regulations protecting our nation's natural resources are complex and dynamic.  Our engineers blend design talent and our experience with regulatory obligations to deliver high quality projects in a timely manner. 

VTN Consulting Public Works provides a wide range of flood control design services including storm drain design, open channel design, detention basin design, bridge and culvert hydraulics, stream bank stabilization, master plan studies, FEMA flood zone studies (re-mapping of flood zones through the CLOMR/LOMR process) and Emergency Action Plans (EAP) for detention basin structures.  These tools, along with many others, enable VTN Consulting Public Works to provide unsurpassed service to our clients.

Las Vegas Wash Gradient Control Structures
The project includes the analysis and design of the Duck Creek Confluence Weir and the Upper Narrows Weir gradient control structures on the Las Vegas Wash.  They are designed to convey a future base flow of 600 cfs and a 100-year storm event flow rate of 22,163 cfs.  The structures are comprised of large diameter rock rip-rap with steel sheet piling cut-off walls.  The weir structures are approximately 450 foot long broad-crest weirs.

The South Edge Headworks Debris/Detention Basin detains runoff from an approximately 23.78 square mile tributary area comprised of undeveloped alluvial fan and mountainous terrain. The Headworks features an earthen fill embankment, a concrete two-staged ogee-crested spillway, and an outlet tower (debris riser) low-level outlet structure. 		  
     
 
Las Vegas Main Branch Channel
The Las Vegas Wash - Main Branch Project involves the design of a regional storm drainage conveyance facility on the Las Vegas Wash, from Cheyenne Avenue to Lake Mead Boulevard. The proposed improvements consist of concrete-lined open channel, transition structures, access ramps, and associated appurtenances.
