Army Corps of Engineers projects prevent $13.3 billion in flood damages during spring rains

Addicks and Barker Reservoirs, located near the intersection of I-10 and State Highway 6 in Houston, helped prevent $2.1 billion in flood damages during the recent spring rain event.

Water flows over the spillway at Lewisville Lake near Dallas after heavy rains in the area in May. About 35 trillion gallons of rain fell across Texas alone in May, with heavy rains also in Oklahoma and Arkansas, putting Army Corps of Engineers reservoirs and flood risk reduction structures to the test.

U.S. Army Corps of Engineers flood risk reduction projects in the south central and southwestern United States prevented an estimated $13.3 billion in damages to local communities and infrastructure during the May-June 2015 flood event, according to recent calculations by Corps officials with the Southwestern Division in Dallas. The most damages prevented were in the greater Dallas-Fort Worth area, where the figure stood at $6.7 billion. Closely following was the greater Houston area with $6.4 billion in flood damages prevented.

“The Army Corps of Engineers flood risk reduction infrastructure—constructed, operated, and maintained with our great partners at all levels—and the benefit that it provides to our nation came to the forefront during this year’s extreme rainfall event, and our structures performed as designed,” said Brig. Gen. David C. Hill, Southwestern Division commander. “The fact that more than $6 billion in damages were prevented in both the Dallas-Fort Worth and Houston areas—the nation’s fourth and fifth largest metropolitan areas—underscore the very robust and tangible benefit this infrastructure provides, along with the other key benefits that our lakes provide throughout the region: hydropower, water supply, and recreation.”

May 2015 was the wettest month on record for both Texas and Oklahoma, and set numerous records throughout the region. Continuing rains from Tropical Storm Bill in June resulted in Army Corps of Engineers flood risk reduction reservoirs and other systems put through a rigorous test to hold the floodwaters and protect local communities and downstream areas.

The breakout for the $6.7 billion in the Dallas-Fort Worth area includes the following: $1.2 billion in damages prevented by the flood damage protection at Grapevine Lake; $2.5 billion at Lake Ray Roberts; and $2.4 billion at Lewisville Lake.

The figures for the $6.4 billion in the greater Houston area include the following: $4.3 billion in damages prevented by the Houston Flood Channel improvements (Brays Bayou and Sims Bayou) and $2.1 billion by the Buffalo Bayou reservoirs (Addicks and Barker reservoirs).

Additionally, the Arkansas River Basin projects (which include parts of Kansas, Oklahoma, and Arkansas) prevented approximately $350 million in flood damages. The Red River Basin projects (which include parts of Oklahoma, Texas, Arkansas, and Louisiana) prevented approximately $150 million in flood damages.

During this flood event, the Southwestern Division had 51 flood control lakes in flood pool and 23 in surcharge pool. Eight new pools of record were set. The Division was in an emergency operation status for two months, which was also the length of time that the McClellan-Kerr Arkansas River Navigation System was not navigable by industry. Corps projects sustained approximately $209 million in damages, much of that at its recreation sites on the lakes. The Southwestern Division covers some 2.3 million acres of public land and water across five states.

Estimating flood damages prevented is a multi-stage process that involves looking at the water level with the flood reduction project (dam or levee) in place, and where the water level would have reached if the dam or levee had not been built. Economists and hydraulic engineers looking at the damages occurring with the dam or levee in place versus no dam or levee in place calculate the estimated economic damages prevented.

Rebecca “Becky” Moyer was recently selected as the Southwestern Division’s Chief of Planning and Policy Division, Programs Directorate for the Southwestern Division, U.S. Army Corps of Engineers. As chief, she is the manager and senior technical advisor for the large and diversified civil works water resources planning program within the region. Moyer is also the leader of the Division’s Planning Community of Practice, and Director of the national Planning Center of Expertise for Water Management and Reallocation Studies.
Prior to this assignment, she was the Southwestern Division’s Senior Economist from 2011 to 2015. Throughout her 28-year Corps career, Moyer has held key Planning positions at all levels within the organization to include assignments at Headquarters, U.S. Army Corps of Engineers, as part of the Great Lakes and Ohio River Division Regional Integration Team and the Office of Water Project Review. She was also an integral member of the Great Lakes and Ohio River Division, , as well as the Huntington, Jacksonville, and Mobile Districts.
“Becky Moyer brings a wealth of policy and planning expertise to this position at a time when these skills are even more critical to our organization than in the past,” said Brig. Gen. David C. Hill, SWD commander. “Her background and vision will serve us well as we face current and future challenges and work to deliver value to our Nation.”
Moyer was a Co-Technical Director of the Inland Navigation Planning Center of Expertise. Her technical areas of expertise are navigation planning and economics (both inland and deep-draft navigation). While in the Jacksonville District, she pioneered the use of navigation simulation modeling for evaluating the economics of harbor improvements and was a key contributor to the development of Harborsym, the Corps’ corporate tool for deep-draft navigation economic analysis.
She is a former proponent and lead instructor of the “Planning Principles and Procedures” course. She holds a Bachelor of Arts in economics and political science from Miami University and a Master of Arts in public administration from Marshall University.
