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.
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.
Pittman Wash - Headworks Debris/Detention Basin
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
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.
Duck Creek Channel
This project includes the design of approximately
1.2 miles of reinforced concrete rectangular open channel between
Las Vegas Boulevard and Silverado Boulevard. The project
also featured reinforced concrete box structures at the street
crossings, one confluence structure, channel transitions and
inlet structures.
Railroad East Detention Basin
The Railroad East Detention Basin project
included the design of a CCRFCD master planned detention basin
and outfall structure. The facilities designed with this
project includes an emergency spillway designed to convey the
PMF storm flow rate, a low-level outlet structure, the outfall
piping, multiple energy dissipaters, access roads and ramps,
fencing, and a flood warning/monitoring station.
