Sunrise Vistas Drainage Improvements
SWI was the lead civil engineer responsible for the drainage improvements of an existing drainage channel located adjacent to the north and east boundary of the Sunrise Vistas subdivision located in Fort Mohave. Due to the proximity of the existing drainage channels the adjacent homes experienced flooding. The original subdivision drainage design included drainage facilities that captured a portion of the flows. SWI utilized the existing facilities in the final design to include concrete weir structures maximizing the existing facilities effectiveness. The new channel design was sized to convey the 100 year storm to reduce the risk of flooding to these homes. SWI provided creative design solutions by utilizing the existing concrete facilities, constructing weirs and channel improvement to slow down channel velocities thereby reducing sediment transport and erosion.
