Atkins selected to prepare update
Atkins has been selected by the Clark County Regional Flood Control District to prepare the 2018 Las Vegas Valley Master Plan Update (MPU) and help safeguard communities and future developments against flooding.
The district is required by state statute to update the Las Vegas Valley Master Plan at least every five years. Atkins delivered consecutive Las Vegas Valley MPUs in 1997, 2002 and 2008, a series of selections only interrupted in 2013 when the district completed the updates internally.
“Our county is growing at a pace of roughly 3,000 new residents each month, many of whom may be unaware of the flood potential here,” said District General Manager Steven Parrish. “Every flood control improvement we implement contributes to reducing risk and protecting our residents. The MPU has evolved into a great tool that guides our local agencies and private consultants when developing both public and private property.”
Atkins will review the current master plan, examine flood control engineering data developed since the 2008 MPU, inventory existing facilities, and reevaluate previous flood control alternatives. The team will carry out the reviews in pursuit of its ultimate goal of assisting the district with developing mitigation solutions for problem flood areas, or “hot spots,” throughout the region.
“The Las Vegas Valley Master Plan is the largest and most complex in the district,” said Atkins Project Manager Harshal Desai, who also led the MPU project team in 2008. “We will leverage our extensive local master planning experience and use our expertise in every aspect of flood control to deliver a comprehensive and effective MPU.”
As part of the MPU, Atkins will develop and deliver the following products:
- The Las Vegas Valley hydrologic model will include more than 1,500 sq miles and define accurate 100-year peak flows and volumes of water for the entire valley.
- A foundational GIS database will represent valley watersheds, regional ﬂood control facilities and associated data. This database will serve as the foundation for all master-planning efforts, which include hydrologic modeling, facility sizing and cost estimating.
- An automated cost estimation tool will predict the future cost of flood control facilities for more accurate forecasting and planning. Costs for all facilities in the region will be summarized to help the district track the value of ﬂood control infrastructure.
By initiating MPU strategies and implementing solutions that include detention basins, channels, storm drains and other flood control measures, the district has removed more than 34,000 acres from Federal Emergency Management Agency flood zones. In addition to safer communities, residents benefit from annual savings in the millions of dollars on flood premiums.
