"70 Years of Flood Control in the Las Vegas Valley:
Historical Floods and the District's Response"
By: Andrew R. Trelease, P.E., CFM
General Manager and Chief Engineer
Clark County Regional Flood Control District
ABSTRACT:
Flooding is the most common and widespread weather-related natural disaster worldwide, affecting both urban and rural areas. In the US, approximately 75% of all presidentially declared natural disasters involve flooding, and all 50 states can experience flash floods. Devastating floods in the Las Vegas Valley between 1950 and 1980 caused millions of dollars in property damaged and potentially much more in lost revenue from the booming tourism industry. In the 1980’s, Clark County politicians and leaders convinced the public to vote for a dedicated funding mechanism to build a multi-billion-dollar flood control system that would take several decades to complete. The Clark County Regional Flood Control District began receiving tax dollars in 1987 with the mission of improving the protection of life and property for residents and visitors from the impacts of flooding. Today Clark County boasts one of the most robust and effective flood control networks in the world, having completed nearly 75% of the facilities on the District’s flood control master plan. Take a tour of the history of flooding in Las Vegas past, present, and future with the newly appointed District General Manager/Chief Engineer.

Andrew R. Trelease is the newly appointed General Manager/Chief Engineer for the Clark County Regional Flood Control District (District). He joined the District in November 2001 and worked as a Principal Engineer and as the Engineering Director prior to becoming the Assistant General Manager in 2017.
