Las Vegas unveils ambitious flood control master plan update

In a recent government meeting, the Clark County Flood Control District presented the 2023 Las Vegas Valley Flood Control Master Plan Update, a critical initiative mandated by Nevada law to be revised every five years. The update aims to assess progress, incorporate new data, and recommend necessary changes to enhance flood management across the valley.

Emily Thornley from Atkins Realis led the presentation, highlighting the extensive research conducted, which included over 300 studies of past projects and input from local entities, including the City of North Las Vegas. The update identifies existing and potential flooding hotspots and utilizes Geographic Information Systems (GIS) to provide a comprehensive view of the flood control network.

The master plan encompasses approximately 4,200 regional facilities, with 3,400 already constructed. Key figures include 804 miles of conveyance facilities, of which 534 miles are completed, valued at over $6 billion. However, 207 miles remain to be built, with an estimated cost of $3.6 billion. Additionally, the plan includes 113 debris detention basins, with 87 constructed and 26 yet to be built, costing around $343 million.

Thornley detailed the progress made in the City of North Las Vegas, which has seen the construction of 14 miles of new conveyance facilities and four new detention basins over the past five years, valued at $122 million. Overall, the entire Las Vegas Valley has a total existing flood control infrastructure valued at approximately $6.7 billion, with a proposed cost for future projects nearing $4 billion.

The meeting concluded with an invitation for questions, emphasizing the importance of community engagement in flood management strategies. The updated master plan is expected to play a vital role in mitigating flooding risks and enhancing public safety in the Las Vegas Valley.
