Flood Risk Reduction History
1949Fort Worth flood kills 11, flood control reservoir
construction advances (Lewisville, Grapevine, Benbrook) 1958Corps completes major Dallas Floodway upgrade
1989-1991Worst floods since 1908. 1998Dallas voters authorize record bond package $246
million for Trinity flood control, transportation and recreation.
1908Dallas flood kills 5, leaves 4,000 homeless, citywithout power for days, massive property damage

Flood Risk ReductionDallas Floodway Project
2007 Water Resources Development Act (WRDA) Section 5141was authorized to raise the levees up to 2 feet, provide recreation(Balanced Vision Plan) and improve pump stations
2009Corps tells City it has rated Dallas Floodway unacceptable;
FEMA withdraws accreditation of levees; city begins maintenanceand construction work to re-certify levees
2010Feasibility Study and Environmental Impact Statementprocess launched to explore what actions are needed to restorecapacity of Dallas Floodway to meet a major storm event.
2011 Corps introduces Risk Assessment process, a cost-effectivemethod for assessing aging dams, to the Dallas Floodway Project. First of this type of study for levees in the Country
Determines Dallas Floodway Project Levees are more resilient and providearound 1,500-year protection

Flood Risk ReductionThe Risk Assessment Process
14
Method for quantifying the risk (likelihood) of various ways a leveecan fail, and the consequences of each failure type
Identifies most cost-effective ways to reduce risk
Overtopping with breach
Successful result: Determined levees moreresilient than previously thought
Narrowed the list of 13potential failure modes to two:
Overtopping with breach ofEast or West Levee
Overtopping of the EastLevee floodwall

Flood Risk ReductionRecommended Flood Risk Management Plan
15
Raise low spots in the levees up to 3 feet to increase flood conveyanceto 277,000 cubic feet per second. This is enough to convey floodwaters ofa major storm that has a 1/2,500 chance of happening any given year
Cost of these two changes: $6.2 million
Old abandonedAT&SF TrestlesProposed for Removal
The Trestles are on 14-foot-centers and collect debris during flooding andstack up floodwaters into the floodway. The embankment acts as a weirand impedes flow down the floodway system
